                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and consolidated financial statements and notes thereto appearing
elsewhere in this Prospectus. All references herein, unless the context
otherwise requires, to the "Company" or "Centocor Diagnostics" refers to
Centocor Diagnostics, Inc. and its subsidiaries. References to the Company or
Centocor Diagnostics include the historical operating results and activities
of, and assets and liabilities assigned to, the business and operations that
comprise the oncology and cardiovascular diagnostic operations that were
previously operated as part of the Diagnostics Division of Centocor, Inc.
("Centocor"). Unless otherwise indicated, the information in this Prospectus
assumes no exercise of the Underwriters' over-allotment option.
 
                                  THE COMPANY
 
  Centocor Diagnostics develops, manufactures and sells diagnostic human health
care products based primarily upon monoclonal antibody technologies. The
Company's products and product candidates focus on disease categories with
large market potential, primarily in oncology and cardiovascular diseases. The
Company is a leading provider of in vitro (outside the body) diagnostic ("IVD")
tests, components and reagents to monitor the efficacy of cancer therapies,
primarily in patients with breast, ovarian or pancreatic cancer. Prior to the
formation of the Company, the business and operations currently conducted by
the Company were operated as a division of Centocor, a biopharmaceutical
company with a primary focus in monoclonal antibody technology. Upon completion
of this offering, Centocor will own       shares of the Company's capital
stock, and will hold approximately  % of the voting power of the Company's
outstanding capital stock.
 
  The Company is currently developing a point-of-care ("POC") cardiovascular
diagnostic test, the P-selectin Profile, designed to allow emergency room
physicians to rapidly and accurately rule in for further treatment patients
suffering Acute Coronary Syndrome ("ACS") and rule out for non-cardiac
treatment or early discharge patients not suffering ACS. The test is further
designed to determine whether patients suffering ACS are suffering a myocardial
infarction ("heart attack"), for whom immediate treatment is critical to
survival, or unstable angina ("UA"), for whom immediate or longer term
treatment is warranted. Within two hours of the onset of a heart attack, more
than 50% of the clinical benefit possible from reperfusion (restoring blood
flow to the heart) is lost because permanent damage to the heart muscle tissue
has occurred. Current tests for a heart attack include electrocardiograms
("ECGs"), which initially fail to diagnose one-half of heart attack cases, and
cardiac enzymes, which begin to detect a heart attack only after irreversible
damage to the heart muscle has occurred. The Company believes that the P-
selectin Profile offers a unique opportunity to improve the quality of care for
ACS patients by complementing existing ECG and cardiac enzyme technologies and
to reduce the costs of unnecessary testing and admissions for patients not
suffering ACS.
 
  Cardiovascular disease is the leading cause of death in the U.S. Heart
attacks alone accounted for approximately 21% of all deaths in the U.S. in
1994. In the U.S., approximately 6.0 million patients enter hospital emergency
departments each year complaining of chest pain. Of these, approximately
500,000 are immediately diagnosed as having a heart attack based on an ECG and
undergo emergency cardiac intervention. An additional 500,000 are ultimately
diagnosed as having had a heart attack based on tests that identify the
presence of cardiac enzymes and additional ECGs and undergo cardiac
intervention, although not before irreversible damage has occurred to the heart
muscle. Approximately 1.5 million are ultimately diagnosed with UA and usually
undergo long-term cardiac treatment and monitoring. The remaining 3.5 million
are diagnosed as not having had a cardiac event and are treated for non-cardiac
conditions or are discharged. Unfortunately, approximately 35,000 of these 3.5
million patients are sent home with an undiagnosed heart attack, and 6,000 of
these patients die within 48 hours. These misdiagnoses account for
approximately 20% of all malpractice settlements paid by emergency
 
                                       1

department doctors. In addition, approximately 2.1 million of these 3.5 million
patients are diagnosed as not having had a cardiac event only after extensive
testing and hospital stays. National statistics indicate that approximately
$4.0 billion of unnecessary medical costs are spent each year on these 2.1
million non-cardiac cases. Current IVD cardiovascular diagnostic tools,
including coagulation tests and cardiac enzyme markers, represented an
approximately $1.0 billion worldwide market in 1996.
 
  After studying the predictive value of individual assays for P-selectin on
the platelet membrane and in blood plasma in more than 2,200 samples, the
Company developed its P-selectin Profile, which measures the status of the
protein P-selectin both on the platelet membrane and in blood plasma, as a
method of assessing platelet activation, an early indicator of ACS. In human
clinical proof-of-principle studies, preliminary data indicates that the P-
selectin Profile has a high predictive value for identifying patients with ACS.
The Company has entered into a collaborative arrangement with Biometric
Imaging, Inc. ("Biometric") to modify an existing FDA-cleared instrument
platform consisting of a computer-controlled, laser-based, static cytometry
imaging system, for use as a POC instrument system designed to deliver the full
utility of the P-selectin Profile.
 
  The Company will seek regulatory clearance for the P-selectin Profile. The
Company will initially file for 510(k) clearance for the combination of the
membrane-bound and plasma-based P-selectin tests as a single diagnostic test.
The Company will also seek clearance for these assays performed on a modified
version of an existing Biometric instrument and for the POC instrument system
platform that it is developing with Biometric. The Company has already
initiated a prospective trial, MAPS (Management of Acute Coronary Syndromes
with P-selectin Profile), which consists of a three-site pilot study to be
followed by a ten-site trial with an aggregate of approximately 1,300 patients.
The Company anticipates enrolling patients in the MAPS trial in early 1998.
 
  Cancer is the second leading cause of death in the U.S. The Company currently
manufactures and sells IVD tests, components and reagents, primarily for the
monitoring of the efficacy of cancer therapies. The Company's primary
technology for these tests is monoclonal antibodies. The Company's monoclonal
antibodies are unique, highly specific proteins that detect the presence, in a
blood sample drawn from a patient, of specific antigens that are produced by
cancer cells. The Company's revenues from the sales of these products were
approximately $40.2 million and $37.6 million, respectively, for the years
ended December 31, 1995 and 1996. During 1996, 64% of the Company's IVD tests
were sold in Europe, while 25% and 11% were sold in Japan and the U.S.,
respectively. The Company sells these products in three formats: (i) completed
kits for performing manual tests; (ii) components for use in automated
instruments that perform the tests; and (iii) supplies of bulk reagents for
inclusion in kits manufactured by third parties.
 
  As a subsidiary of Centocor, the Company realizes significant strategic and
operating benefits from a shared base of technology in monoclonal antibodies
generally, and specifically in the cardiovascular and oncology areas, research
and development skills and procedures, clinical trial management techniques and
data, the ability to have its product candidates included in Centocor's
clinical trials and common marketing activities within the same disease area
that are targeted to the same decision makers and institutions. Centocor's
leading product is ReoPro, a therapeutic drug that is effective in preventing
blood clotting by inhibiting the aggregation of platelets. The Company believes
that the P-selectin Profile can be utilized as an indicator of situations where
ReoPro (and other platelet aggregation inhibitors to the extent they become
available) is effective as a therapeutic treatment. The Company also believes
that the opportunity for the P-selectin Profile to be included with ReoPro in a
cardiovascular disease management program offers significant clinical and
marketing benefits. The Company believes it is uniquely positioned to benefit
from the management systems and infrastructure in place at Centocor.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing the Class A Common Stock offered hereby. All
statements other than statements of historical facts included in this
Prospectus, including, without limitation, statements regarding the Company's
business strategy, product development plans and objectives, future operations
and future industry conditions, are forward-looking statements. Although the
Company believes that the expectations reflected in such forward-looking
statements are reasonable, it can give no assurance that such expectations
will be met. Important factors that could cause actual results to differ
materially from the Company's expectations are disclosed below and elsewhere
in this Prospectus.
 
INITIAL DEPENDENCE OF THE COMPANY ON MATURE PRODUCTS
 
  The Company's present business consists primarily of IVD tests, components
and reagents that were developed and commercialized in the 1980's. Three of
these products (CA 15-3 (breast cancer), CA 19-9 (pancreatic cancer), CA 125
II (ovarian cancer)) accounted for more than 85% of the Company's revenues in
1996. While these products have significant product market positions and enjoy
relatively high levels of profitability, the Company believes that any
expansion of product sales from these products will be modest. In recent
years, the Company has experienced a change in its IVD test product mix from
completed kits to components for automated systems and bulk reagent sales.
This product shift, which is expected to continue for the next few years, has
resulted in average unit price declines. See "Business--Oncology Diagnostics."
If this product shift continues, and is not offset by increases in volume
growth, revenues and net income for the Company's oncology products may be
reduced. In addition, there can be no assurance that competition will not
erode the Company's market position for oncology products in the future,
potentially reducing revenue and net income.
 
DEPENDENCE ON NEW PRODUCT DEVELOPMENT FOR ENHANCED GROWTH AND PROFITABILITY
 
  The Company is dependent on the successful development and commercialization
of new products, particularly the P-selectin Profile, in order for the Company
to realize future revenue growth and profitability. There can be no assurance
that any new products will be successfully developed and commercialized on a
timely basis, if at all. Even if successfully developed and commercialized,
there is no assurance that market penetration will be obtained at a level
necessary for the Company to maintain profitability. The successful
commercialization of the P-selectin Profile is dependent upon the modification
of existing diagnostic technologies by the Company and existing
instrumentation technologies by Biometric, which may not be successfully
completed. Because chest pain management is highly protocol driven, the
successful commercialization of the P-selectin Profile will also be highly
dependent upon its inclusion in the U.S. national "Best Practices" chest pain
management protocol promulgated by the American Heart Association ("AHA") and
the American College of Cardiology ("ACC"). This will require the Company to
demonstrate that the P-selectin Profile and the POC instrument system are
cost-effective, accurate and rapid diagnostic tests for chest pain patients.
There can be no assurance that the P-selectin Profile will be included in the
U.S. national "Best Practices" chest pain management protocol. In addition,
there can be no assurance that any regulatory approvals or clearances
necessary for the marketing of the P-selectin Profile will be obtained, or if
obtained, will be on the time schedule that the Company is currently
anticipating. Failure to receive regulatory approval or clearance, or
substantial delay in regulatory approval or clearance, will significantly
impact the Company's expected revenues from the P-selectin Profile and its
ability to maintain profitability. The Company's cost of conducting clinical
trials in connection with the development of the P-selectin Profile could
increase from the present estimated amounts if Centocor's Gusto IV Trial is
terminated early and the Company decides to continue its portion of the trial
or to begin a new trial completely at its own cost.
 
DEPENDENCE ON THIRD PARTIES
 
  In connection with the development and commercialization of the P-selectin
Profile, the Company has entered into an agreement with Biometric pursuant to
which Biometric is developing a POC instrument system based on Biometric's
existing instrument platform. The successful development of the POC instrument
system is
 
                                       5
<PAGE>
 
essential to the successful commercialization of the P-selectin Profile. There
can be no assurance that Biometric will successfully develop the POC
instrument system or that, in the event Biometric is unsuccessful, the Company
will be able to develop, either independently or with third parties, an
alternative POC instrument system.
 
  The Company focuses its internal technical resources on the development of
new products, while outsourcing much of its basic research activities with
third parties, particularly from academic and medical research sources.
Historically, this has provided the Company with access to a variety of new
technology options, while allowing the Company to focus its limited resources
on those opportunities that the Company believes will have the highest
likelihood for success. The Company must compete with numerous other third
parties who seek access to these same research sources, many of whom have
significantly more resources to fund sponsored research and advisory
relationships with those institutions and individuals whose research is of
most interest to the Company. While the Company believes it has good
relationships with the individuals and centers of research who conduct
research on behalf of the Company, there can be no assurance that these
sources will continue to be available to it, or that competition will not make
the cost of access to these sources prohibitively expensive. Also, the Company
cannot be assured that new centers of important research capability with which
it has no relationships will not emerge that will result in the Company not
having access to innovative research that may be available to its competitors.
In either case, the result could have a materially adverse impact upon the
Company.
 
CUSTOMER CONCENTRATION
 
  Substantially all of the Company's current revenues are generated by the
sale of the Company's IVD tests, components and reagents to a limited number
of distributors and automated instrument partners. Therefore, the level of the
Company's revenues is dependent, in part, upon the level of effort and success
of its distributors and automated instrument partners marketing and selling
the Company's IVD products to end users. The Company's distributors and
automated instrument partners may also compete with the Company. Although the
Company believes its distributors and automated instrument partners have an
economic incentive to succeed in performing their marketing and selling
activities, the amount and timing of resources that they devote to these
activities is not within the control of the Company. There can be no assurance
that such parties will perform as expected or that any revenue will be derived
from such arrangements. If any of the Company's distributors or automated
instrument partners fails to perform as expected, and the Company is unable to
distribute the products directly to end users, it is likely that revenues
would decline. Even if the Company is able to replace a distributor or adapt
its IVD tests for use on another automated instrument partner's instrument,
there is no assurance that such arrangement would be on terms and conditions
as advantageous to the Company as the prior arrangements. During 1996,
approximately 70% of the Company's sales were received from four distributors
or automated instrument partners as follows: 25% to TFB, Inc., 19% to
Boehringer Mannheim GmbH, 14% to Abbott Laboratories and 12% to Cis bio
International. During the first nine months of 1997, approximately 66% of the
Company's sales were received from four distributors or automated instrument
partners as follows: 25% to TFB, Inc., 18% to Boehringer Mannheim GmbH, 16% to
Abbott Laboratories and 7% to CIS bio International.
 
GOVERNMENT REGULATION; NO ASSURANCE OF OBTAINING REGULATORY APPROVALS
 
  The testing, manufacture and sale of the Company's products are subject to
regulation by numerous governmental authorities, principally the U.S. Food and
Drug Administration (the "FDA") and corresponding state and foreign regulatory
agencies. Pursuant to the Federal Food, Drug, and Cosmetic Act, and the
regulations promulgated thereunder, the FDA regulates the preclinical and
clinical testing, manufacture, labeling, distribution and promotion of medical
devices. The Company will not be able to commence marketing or commercial
sales in the U.S. of any new product under development until it receives
clearance or approval from the FDA, which can be a lengthy, expensive and
uncertain process. Noncompliance with applicable requirements can result in,
among other things, fines, injunctions, civil penalties, recall or seizure of
products, total or partial suspension of production, failure of the government
to grant premarket clearance or premarket approval for devices, withdrawal of
marketing clearances or approvals, and criminal prosecution. The FDA also has
the authority to request recall, repair, replacement or refund of the cost of
any device manufactured or distributed by the Company.
 
                                       6
<PAGE>
 
  Any device manufactured or distributed by the Company pursuant to FDA
clearance or approvals are subject to pervasive and continuing regulation by
the FDA and certain state agencies. Before a new device can be introduced in
the market, the manufacturer must generally obtain FDA clearance of a 510(k)
notification or FDA approval of a pre-market approval ("PMA") application. The
PMA approval process is more expensive, uncertain and lengthy than the 510(k)
clearance process. The Company is uncertain of the regulatory path to market
that the FDA will ultimately apply to the Company's products currently in
development, including the P-selectin Profile and the related POC instrument
system. There can be no assurance that with respect to any of the Company's
products in development, the FDA will not determine that the Company must
adhere to the more costly, lengthy and uncertain PMA approval process.
Modifications to a device that is the subject of an approved PMA application,
its labeling or manufacturing process may require approval by the FDA of a PMA
supplement or a new PMA application. For any devices that are cleared through
the 510(k) process, modifications or enhancements that could significantly
affect safety or effectiveness, or constitute a major change in the intended
use of the device, will require new 510(k) submissions.
 
  There can be no assurance that the Company will be able to obtain necessary
regulatory approvals or clearances for its products on a timely basis, if at
all, and delays in receipt of or failure to receive such approvals or
clearances, the loss of previously received approvals or clearances,
limitations on intended use imposed as a condition of such approvals or
clearances, or failure to comply with existing or future regulatory
requirements would have a material adverse effect on the Company.
 
  Before the manufacturer of a device can submit the device for FDA clearance
or approval, it generally must conduct a clinical investigation of the device.
Although clinical investigations of most devices are subject to the
investigational device exemption ("IDE") requirements, clinical investigations
of IVD tests, such as all of the Company's oncology products and certain
products under development, including the P-selection Profile, are exempt from
the IDE requirements, including the need to obtain the FDA's prior approval,
provided the testing is noninvasive, does not require an invasive sampling
procedure that presents a significant risk, does not intentionally introduce
energy into the subject, and is not used as a diagnostic procedure without
confirmation by another medically established test or procedure. In addition,
the IVD tests must be labeled for research use only ("RUO") or investigational
use only ("IUO"), and distribution controls must be established to assure the
IVD tests distributed for research or clinical investigation are used only for
those purposes.
 
  Manufacturers of medical devices for marketing in the U.S. are required to
adhere to applicable regulations setting forth detailed current Quality System
Regulation ("QSR") requirements, which include testing, control and
documentation requirements. Manufacturers must also comply with Medical Device
Reporting ("MDR") requirements that a manufacturer report to the FDA any
incident in which its product may have caused or contributed to a death or
serious injury, or in which its product malfunctioned and would be likely to
cause or contribute to a death or serious injury upon recurrence. Labeling and
promotional activities are subject to scrutiny by the FDA and, in certain
circumstances, by the Federal Trade Commission. Current FDA enforcement policy
prohibits the marketing of approved medical devices for unapproved uses.
 
  The Company is subject to routine inspection by the FDA and certain state
agencies for compliance with QSR requirements and other applicable
regulations. There can be no assurance that the Company will not incur
significant costs to comply with laws and regulations in the future or that
such laws and regulations will not have a material adverse effect upon the
Company.
 
  The use of the Company's products is also affected by the Clinical
Laboratory Improvement Amendments of 1988 ("CLIA") and related federal and
state regulations that provide for regulation of laboratory testing. The scope
of these regulations includes quality control, proficiency testing, personnel
standards and federal inspections. CLIA categorizes tests as "waived,"
"moderately complex" or "highly complex," on the basis of specific criteria.
There can be no assurance that any future amendment of CLIA or the
promulgation of additional regulations impacting laboratory testing would not
have a material adverse effect on the Company.

UNCERTAINTY OF ADDITIONAL FUNDING REQUIREMENTS; OPERATING LOSSES
 
  While the Company believes that its available cash, anticipated cash from
operations and funds from its existing credit agreements with Centocor,
together with the proceeds from this offering, will be sufficient to satisfy
its funding needs for the foreseeable future, there can be no assurance the
Company will not require additional capital. The Company anticipates that it
will incur operating losses in 1998 and 1999 as a result of increased spending
on research and development and the expected initiation of commercialization
expenditures related to the Company's P-selectin Profile. The Company's future
liquidity and capital requirements are dependent on several factors. These
include the financial performance of its existing IVD tests, components and
reagents, the cost and timing of the development, clinical trial, regulatory
approval and commercialization of its new products, in particular the P-
selectin Profile, and the terms and conditions of possible joint ventures and
technology licensing and development arrangements required for its new
products. If, for any reason, the Company's working capital and capital
expenditure requirements are greater than expected, additional financing may
be required by the Company. If the Company has insufficient funds to meet its
capital needs, it will be necessary to obtain funding from third parties,
which may not be available when needed or on terms acceptable to the Company.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations."
 
UNCERTAINTIES REGARDING HEALTH CARE REIMBURSEMENT AND REFORM
 
  The Company's ability to commercialize products successfully may depend in
part on the extent to which reimbursement for the costs of such products will
be available from governmental health administration authorities, private
health insurers and other organizations. Significant uncertainty exists as to
the reimbursement status of newly approved health care products, and there can
be no assurance that adequate third party coverage will be available for the
Company to maintain price levels sufficient for realization of an appropriate
return on its investment in developing new products. Government and other
third party payors are increasingly attempting to contain health care costs by
limiting both coverage and the level of reimbursement for new products, and by
refusing, in some cases, to provide any coverage for uses of approved products
for indications for which the FDA has not granted marketing approval or
clearance. Recent initiatives to reduce governmental deficits in the U.S. and
elsewhere and to reform health care delivery are increasing these cost
containment efforts. As managed care organizations continue to expand as a
means of containing health care costs, the Company believes there may be
attempts by such organizations to restrict the use of, or delay authorization
to use, new products, such as those being developed by the Company, pending
completion of cost/benefit analyses of such products by those managed care
organizations. If adequate coverage and reimbursement levels are not provided
by government and other third party payors for uses of the Company's products,
the market acceptance of these products would be adversely affected.
 
RAPID TECHNOLOGICAL CHANGE
 
  A fundamental aspect of the market in which the Company competes is the
ability to develop and introduce new technology. The history of the IVD test
business has been one of rapid technological change. The Company believes that
this dynamic will continue to be a critical factor in future success, subject
to the new additional factors of disease management: health economics and
clinical outcome performance. The range of new technology applications is
becoming increasingly broad, encompassing new disease markers (immunoassay,
cellular and DNA-based), instrumentation, algorithms and information systems.
The Company cannot assure that new competitors, whether from academic
programs, other health care competitors, or from unrelated markets, will not
be successful in developing new technologies that will make the Company's
products obsolete or non-competitive in the future.
 
COMPETITION
 
  The oncology IVD test market in which the Company competes is highly
competitive. The Company's competitors include a broad array of health care
companies that develop and manufacture diagnostic tests and instrumentation
for research, clinical and hospital-based laboratories. Many of these
competitors are multinational, multi-billion dollar companies, all of whom
have substantially greater financial, marketing,
 
                                       8
<PAGE>
 
distribution, manufacturing and technical resources than the Company. There
can be no assurance that the activities of others will not render the
Company's products obsolete or uncompetitive. The cardiovascular IVD market,
likewise, is dominated by the same large diagnostic companies. While these
companies do not currently have a significant presence in the emergency
department segment of the market, they have the resources necessary to rapidly
develop and commercialize a product competitive with the P-selectin Profile
and enter this segment. See "Business--Competition."
 
RELATIONSHIP WITH CENTOCOR
 
  Upon completion of this offering, Centocor will own 100% of the Company's
outstanding Class B Common Stock, which will represent approximately   % of
the outstanding Common Stock of the Company (approximately   % if the
Underwriters' over-allotment option is exercised in full) and approximately
  % of the combined voting power of the Company's outstanding Common Stock
(approximately   % if the Underwriters' over-allotment option is exercised in
full). As a result, Centocor will be able to effectively control all matters
requiring approval by the shareholders of the Company, including the election
of the Board of Directors and preventing a change in control of the Company.
The Class B Common Stock is convertible into Class A Common Stock, subject to
certain limitations set forth in the Company's Amended and Restated Articles
of Incorporation. See "Description of Capital Stock." Centocor has no
agreement with the Company not to sell or distribute its shares of the
Company's Common Stock and, except for the restrictions in the Underwriting
Agreement set forth below, there can be no assurance that Centocor will
maintain its ownership of the Company's Class B Common Stock. Pursuant to the
Underwriting Agreement, Centocor has agreed, subject to certain exceptions,
not to sell or otherwise dispose of, directly or indirectly, any shares of
Common Stock owned by it for a period of 180 days after the date of this
Prospectus without the prior written consent of Morgan Stanley & Co.
Incorporated. See "Underwriters."
 
  Centocor must beneficially own at least 80% of the total combined voting
power of all classes of the Company's stock entitled to vote and at least 80%
of the total number of shares of each class of nonvoting stock in order to be
able to effect a tax-free spin-off of the Company under the Internal Revenue
Code of 1986, as amended (the "Code"). Because Centocor may seek to maintain
its beneficial ownership percentage of the Company for tax planning purposes
or otherwise and may not desire to acquire additional shares of Common Stock
in connection with a future issuance of shares by the Company, the Company may
be constrained in its ability to raise equity capital in the future or to
issue Common Stock or other equity securities in connection with acquisitions.
See "Relationship with Centocor, Inc."
 
  By virtue of its controlling ownership and the terms of a tax sharing
agreement (the "Tax Sharing Agreement") to be entered into between the Company
and Centocor, Centocor will effectively control virtually all of the Company's
tax decisions for as long as the Company is a member of Centocor's
consolidated group for federal income tax purposes. In such event, Centocor
will have sole authority to respond to and conduct all tax proceedings
(including tax audits) relating to the Company, to file federal, certain state
and local returns on behalf of the Company and to calculate the amount of the
Company's liability to Centocor under the Tax Sharing Agreement. Centocor may
choose to contest, compromise or settle any adjustment or deficiency proposed
by the relevant taxing authority in a manner that may be beneficial to
Centocor and detrimental to the Company.
 
  The Code generally requires beneficial ownership by Centocor of at least 80%
of the total voting power and value of the outstanding stock of the Company in
order to include the Company as a member of the Centocor consolidated group
for federal income tax purposes. Each member of a consolidated group for
federal income tax purposes is jointly and severally liable for the federal
income tax liability of each other member of the consolidated group.
Accordingly, during the period in which the Company is included in Centocor's
consolidated group, the Company could be liable if such liability or tax is
incurred, and not discharged, by any other member of Centocor's consolidated
group. The Company is, and after the offering may continue to be, included in
Centocor's consolidated group for federal income tax purposes. See
"Relationship with Centocor, Inc.--Tax Sharing Agreement."

  Prior to the completion of the offering, Centocor and the Company will enter
into certain intercompany agreements, including an agreement pursuant to which
Centocor will provide various corporate services to the Company that may be
material to the conduct of the Company's business (the "Services Agreement").
With respect to matters covered by the Services Agreement, the relationship
between Centocor and the Company is intended to continue in a manner generally
consistent with past practices. Because the Company is currently a wholly
owned subsidiary of Centocor, none of the intercompany agreements will result
from arm's-length negotiations. These agreements may include terms and
conditions that may be more or less favorable to the Company than terms
contained in similar agreements negotiated with third parties.
 
  Various conflicts of interest between the Company and Centocor could arise
following the completion of this offering, and persons serving as directors,
officers and employees of both the Company and Centocor may have conflicting
duties to each. Dominic J. Caruso and George D. Hobbs, directors of the
Company, are also employees and officers of Centocor. Ownership interests of
directors or officers of the Company in the common stock of Centocor could
also create or appear to create potential conflicts of interest when directors
and officers are faced with decisions that could have different implications
for the Company and Centocor. In addition, for financial reporting purposes,
the Company's financial results will be included in Centocor's consolidated
financial statements. The members of the Board of Directors of the Company who
are affiliated with Centocor will consider not only the short-term and long-
term impact of financial and operating decisions on the Company, but also the
impact of such decisions on Centocor's consolidated financial results. In some
instances, the impact of such decisions could be disadvantageous to the
Company while advantageous to Centocor.
 
LIMITED HISTORY AS A STAND-ALONE CORPORATION; LIMITED RELEVANCE OF HISTORICAL
FINANCIAL INFORMATION
 
  Prior to August 1997, the Company operated as a division of Centocor and has
a limited history operating as a stand-alone corporation. As a stand-alone
corporation, Centocor has no obligation to provide assistance to the Company
or any of its subsidiaries except as described in "Relationship with Centocor,
Inc." In addition, the financial information included herein may not
necessarily reflect the results of operations, financial position and cash
flows of the Company in the future or what the results of operations,
financial position and cash flows would have been had the Company been a
separate, stand-alone entity during the periods presented. The financial
information included herein does not reflect changes that may occur in the
funding and operations of the Company as a result of this offering, some of
which may be significant. See "Relationship with Centocor, Inc.," "Selected
Consolidated Financial Data," including the discussion of the assumptions
reflected therein, and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
PATENTS AND LICENSING ARRANGEMENTS
 
  Products currently being marketed, developed or considered for development
by the Company are in the area of biotechnology, an area in which there are
extensive patent filings. The patent position of biotechnology firms generally
is highly uncertain and involves complex legal and factual questions. To date,
no consistent policy has emerged regarding the breadth of claims allowed in
biotechnology patents. Accordingly, there can be no assurance that patent
applications owned or licensed by the Company will result in patents being
issued or that, if issued, such patents will afford protection against
competitors with similar technology. In addition, there can be no assurance
that products covered by such patents, or any other products developed by the
Company or subject to licenses acquired by the Company, will not be covered by
third party patents, in which case continued development and marketing of such
products would require a license under such patents. There can be no assurance
that such required licenses will be available to the Company or its licensees
on acceptable terms.
 
  Other entities have filed applications for or have been issued patents and
are expected to obtain additional patents to which the Company may need to
acquire rights. The extent to which Centocor Diagnostics may need to obtain
rights to any such patents or to contest their scope of validity will depend
on final product formulation and other factors. The ability to license any
such patents and the likelihood of successfully contesting the scope or
validity of such patents are uncertain and the costs associated therewith may
be significant. If the Company is required to acquire rights to valid and
enforceable patents but cannot do so at a reasonable cost, the Company's
 
                                      10
<PAGE>
 
ability to manufacture or market its products in the country of issuance of
any such patent may be materially adversely affected.
 
  There has been substantial litigation regarding patent and other intellec-
tual property rights in the biotechnology industry. Litigation may be neces-
sary to enforce certain intellectual property rights of the Company. Any such
litigation could result in substantial cost to and diversion of effort by the
Company.
 
POTENTIAL QUARTERLY FLUCTUATIONS IN FUTURE OPERATING RESULTS
 
  The Company has not yet completed a full quarter as a stand-alone
corporation. There can be no assurance that the Company will achieve
profitability on a quarterly or annual basis in the future. The Company
believes that future operating results will be subject to quarterly
fluctuations due to a variety of factors, including whether and when new
products are successfully developed and introduced by the Company, market
acceptance of current or new products, regulatory delays, product recalls,
manufacturing delays, shipment problems, seasonal customer demand, the timing
of significant orders, the timing of contract revenues, changes in
reimbursement policies, competitive pressures on average selling prices,
currency fluctuations, changes in the mix of products sold and patent
conflicts. Operating results would also be adversely affected by a downturn in
the market for the Company's current and future products, if any, order
cancellations or order rescheduling. Because the Company is continuing to
increase its operating expenses for personnel and new product development, the
Company's operating results would be adversely affected if its sales did not
correspondingly increase or if its product development efforts are
unsuccessful or subject to delays.
 
EXPOSURE TO CURRENCY FLUCTUATIONS
 
  In 1996, approximately 29% of the Company's sales were denominated in
foreign currencies and converted to U.S. dollars pursuant to conversion
provisions set forth in the respective agreements to determine payment amounts
owed to the Company. Currency fluctuations have in the past and may in the
future cause reported sales to fluctuate from period to period regardless of
the fluctuation in the volume of such sales in foreign currencies. As a
result, the Company's operating results are subject to currency fluctuations.
 
PRODUCT LIABILITY
 
  The testing and marketing of diagnostic products entail an inherent risk of
product liability. In addition to its current product offerings, the Company
expects to market new cardiovascular diagnostic products, including the P-
selectin Profile, for use in the emergency department of hospitals, which may
increase the risk of product liability claims against the Company, as there
has been significant litigation in the area of emergency medicine. In
addition, there can be no assurance that the Company will not experience an
increase in product liability claims to the extent the Company's product mix
shifts from products that solely monitor the progression of disease to
products that screen for diseases. Centocor Diagnostics maintains limited
product liability insurance coverage. The Company may be materially adversely
affected by a successful product liability claim in excess of any insurance
coverage. There can be no assurance that product liability insurance coverage
will continue to be available to the Company in the future on reasonable terms
or at all.
 
SKILLED PERSONNEL
 
  The Company's success will depend, in large part, on the Company's continued
ability to attract and retain highly qualified management, scientific,
manufacturing and sales and marketing personnel. Competition for such
personnel is intense. There can be no assurance that the Company will be able
to attract or retain such personnel in the future.
 
LACK OF PRIOR PUBLIC MARKET AND POSSIBLE STOCK PRICE VOLATILITY
 
  Prior to the offering, there has been no public market for the shares of
Class A Common Stock of the Company, and there can be no assurance that an
active public market for the shares of Class A Common Stock
 
                                      11
<PAGE>
 
will develop or be sustained or that the market price for the Class A Common
Stock will not decline below the public offering price set forth on the cover
page of this Prospectus. Securities markets in general, and new public
offerings in particular, have from time to time experienced significant
fluctuations in price and traded volumes unrelated to the operating
performance of individual companies. Biotechnology companies have in the past
been, and may in the future be, especially susceptible to highly volatile
market price fluctuations. Announcements concerning the Company's or its
competitors' products, technical innovations, operating results, clinical
investigation results or regulatory developments, as well as reimbursement
policy changes, health care industry news and general economic conditions and
other external factors may have a significant impact on the market price of
the Class A Common Stock. See "Underwriters--Price of the Offering."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial amounts of Class A Common Stock in the public market,
whether by purchasers in the offering or other shareholders of the Company, or
the perception that such sales could occur, may materially and adversely
affect the market price of the Class A Common Stock. Upon completion of the
offering, the shares of Class A Common Stock offered hereby will be freely
tradeable without restriction or further registration under the Securities Act
of 1933, as amended (the "Securities Act"), by persons other than executive
officers and directors of Centocor or the Company (the "Restricted Persons").
 
  Upon completion of the offering, Centocor will own 100.0% of the Company's
outstanding Class B Common Stock, which will represent approximately   % of
the outstanding Common Stock of the Company (approximately   % if the
Underwriters' over-allotment option is exercised in full). The shares of
Common Stock that are held by Centocor and certain Restricted Persons are
subject to a "lock-up" agreement, under which Centocor and such Restricted
Persons have agreed, subject to certain exceptions, not to offer, sell,
contract to sell or otherwise dispose of any shares of Common Stock, without
the prior written consent of Morgan Stanley & Co. Incorporated, for a period
of 180 days after the date of this Prospectus. Following such period, Centocor
(following conversion of the Class B Common Stock it owns to shares of Class A
Common Stock) and any such Restricted Person who is an affiliate of the
Company may sell such shares only pursuant to the requirements of Rule 144
under the Securities Act or pursuant to an effective registration statement
under the Securities Act. A decision by Centocor to sell such shares following
the 180-day lock-up period could materially and adversely affect the market
price of the Class A Common Stock. The Company and Centocor have entered into
a registration rights agreement, which requires the Company to effect a
registration statement covering some or all of the shares of Class A Common
Stock to be owned by Centocor upon conversion of the Class B Common Stock
owned by Centocor and any other shares of Class A Common Stock otherwise
acquired by Centocor, subject to certain terms and conditions. The Company
intends to register a total of      shares of Class A Common Stock reserved
for issuance under its Stock Option Plans as soon as practicable following the
date of this Prospectus. See "Relationship with Centocor, Inc.," "Description
of Capital Stock," and "Shares Eligible for Future Sale."
 
ANTI-TAKEOVER EFFECTS OF CERTAIN ARTICLES OF INCORPORATION AND BYLAW
PROVISIONS
 
  The holders of Class A Common Stock are entitled to one vote per share and
holders of Class B Common Stock are entitled to 10 votes per share. Holders of
Class A Common Stock and Class B Common Stock generally vote together as a
single class. The Class B Common Stock held by Centocor is convertible into
Class A Common Stock under certain conditions set forth in the Company's
Amended and Restated Articles of Incorporation. See "Description of Capital
Stock."
 
  Upon completion of this offering, the Company's Board of Directors will have
the authority to issue up to      shares of capital stock and to determine the
price, rights, preferences, privileges and restrictions, including voting
rights of such shares, without any further vote or action by the Company's
shareholders. Such charter provisions could have the effect of delaying or
preventing a change of control of the Company. The rights of the holders of
Common Stock may be subject to, and may be adversely affected by, the rights
of the holders of any capital stock that may be issued in the future. The
issuance of any such shares of capital stock, while
 
                                      12
<PAGE>
 
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 current plans to issue any shares of such capital
stock.
 
  The Company's Articles of Incorporation, as amended and restated, or Bylaws,
as applicable, among other things (i) provide that the number of directors
will determined from time to time by the Board of Directors through a
resolution adopted by a majority of the Board of Directors, (ii) permit
vacancies on the Board of Directors that may occur between annual meetings and
newly created seats to be filled only by the Board of Directors and not by the
shareholders, (iii) do not permit the shareholders to call special meetings of
shareholders, (iv) provide that the Board of Directors, without action by the
shareholders, may issue and fix the rights and preferences of shares of new
classes or series of the Company's capital stock, and (v) permit shareholder
action, without a meeting, upon the written consent of shareholders who would
have been entitled to cast the minimum number of votes that would be necessary
to authorize the action at a meeting at which all shareholders entitled to
vote on such action were present and voting without prior notice to the
remaining shareholders. These provisions may have the effect of delaying,
deferring or preventing a change of control of the Company without further
action by the shareholders, may discourage bids for the Common Stock at a
premium over the market price of the Common Stock and may adversely affect the
market price of, and the voting or other rights of the holders of, the Common
Stock. See "Description of Capital Stock."
 
DILUTION
 
  Based upon the initial public offering price per share of $    (and assuming
no exercise of the Underwriters' over-allotment option), the Company's net
tangible book value per share of Common Stock as of September 30, 1997, would
have been $   . This represents an immediate increase in net tangible book
value of $    per share to the existing shareholder and an immediate dilution
of $    per share to purchasers of the Class A Common Stock in the offering.
See "Dilution."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the shares of Class A
Common Stock offered hereby are estimated to be $    ($    if the
Underwriters' over-allotment option is exercised in full), assuming a public
offering price of $    per share and after deducting estimated underwriting
discounts and commissions and estimated offering expenses payable by the
Company. Approximately $20.0 million of the net proceeds from this offering
will be utilized through 2002 for capital expenditures related primarily to
the cardiovascular diagnostic program, with the balance used for working
capital, product research and development and other corporate purposes, which
may include expenses associated with the expansion of sales and marketing
activities, property, plant and equipment and for general corporate purposes.
 
                                DIVIDEND POLICY
 
  The Company does not anticipate declaring or paying any cash dividends in
the foreseeable future and intends to retain its earnings, if any, for the
development and expansion of its business operations. In 1994, 1995 and 1996,
and in the first nine months of 1997, the Company distributed to Centocor
$12.4 million, $11.0 million, $12.8 million and $1.0 million, respectively.

                                CAPITALIZATION
 
  The following table sets forth the consolidated cash balance and
capitalization of the Company at September 30, 1997 and as adjusted to give
effect to the sale of the shares of Class A Common Stock in this offering (at
an assumed offering price of $    per share and after deducting underwriting
discounts and commissions and estimated offering expenses).

                                   DILUTION
 
  The net tangible book value of the Company at September 30, 1997 was $   ,
or $    per share of Common Stock. Net tangible book value per share
represents the amount of total tangible assets less total liabilities of the
Company, divided by the number of shares of Common Stock outstanding. After
giving effect to the proposed sale by the Company of     shares of Class A
Common Stock in this offering at an assumed offering price of $    per share
(calculated after deduction of estimated underwriting discounts and
commissions and estimated expenses associated with the offering), the pro
forma net tangible book value of the Common Stock at September 30, 1997 would
have been $   , or $   per share. This represents an immediate increase in net
tangible book value of $    per share to existing shareholders and an
immediate dilution in net tangible book value of $    per share to the
purchasers of the Class A Common Stock in the offering.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
  Investors are cautioned that forward-looking statements involve risks and
uncertainties including economic, competitive, governmental, technological and
other factors that may affect the Company's business prospects.
 
OVERVIEW
 
  Centocor Diagnostics develops, manufactures and sells diagnostic human
health care products based primarily upon monoclonal antibody technologies.
The Company's products and product candidates focus on disease categories with
large market potential, primarily in oncology and cardiovascular diseases. The
Company is a leading provider of in vitro (outside the body) diagnostic
("IVD") tests, components and reagents to monitor the efficacy of cancer
therapies, primarily in patients with breast, ovarian and pancreatic cancer.
The Company sells its IVD products in three formats: (i) completed kits
("Kits"), (ii) components for automated systems ("Components") and (iii) bulk
reagents for kits ("Reagents").
 
  Prior to the formation of the Company, the business and operations currently
conducted by the Company were operated as a division of Centocor, a
Pennsylvania corporation formed in 1979. The financial information included
herein may not necessarily reflect the results of operations, financial
position and cash flows of the Company in the future or what the results of
operations, financial positions and cash flows would have been had the Company
been a separate, stand-alone entity during the periods presented.
 
  The Company recently received marketing clearance for its CA 15-3 (breast
cancer) Kits in the U.S. and anticipates seeking marketing clearance of its CA
19-9 (pancreatic cancer) Kits in the U.S. Additional marketing clearance will
be necessary prior to commercialization in the U.S. by the Company's automated
instrument partners of IVD tests incorporating the Company's Components or
Reagents, including CA 15-3 and CA 19-9.
 
  The Company's sales and gross profits are impacted by the mix of products
sold, pricing levels and foreign currency fluctuations. The Company's sales
and gross profit declined in 1996 compared to 1995, principally due to lower
average unit sales prices from a shift in the Company's product mix from Kits
to Components and Reagents. In 1996, more than 50% of the Company's sales
revenues were generated by sales of Kits. The Company receives higher average
unit sales prices on Kits as compared to Components and Reagents. Furthermore,
while the gross margin percentage for Kits are slightly higher than for
Components, they are significantly lower than for Reagents. The Company
expects that this shift in product mix will continue over the next few years.
However, the Company believes that the shift in product mix will be offset by
increases in volume growth for these products, especially as products
incorporating the Company's IVD tests receive further regulatory approval
worldwide.
 
  In 1996, approximately 29% of the Company's sales were denominated in
foreign currencies and converted to U.S. dollars pursuant to conversion
provisions set forth in the respective agreements to determine payment amounts
owed to the Company. Currency fluctuations may cause reported sales to
fluctuate from period to period regardless of the fluctuation in the volume of
such sales in foreign currencies. As a result, the Company's operating results
are subject to currency fluctuations.
 
  The Company intends to pursue growth through the introduction of novel
diagnostic products that address large markets with unmet clinical and
economic needs. The Company believes that the P-selectin Profile fulfills
these criteria. See "Business--Cardiovascular Diagnostics." The level of
future sales of diagnostic products, particularly the P-selectin Profile, will
be dependent upon several factors including, but not limited to, the
development of instrumentation technology by Biometric, the timing and extent
of future regulatory approvals of the Company's products, approval and
commercialization of competitive products and ultimately the degree of
acceptance of the Company's products in the marketplace. The level of oncology
diagnostic sales is also dependent upon the extent of and timing of Reagent
sales to partners developing new automated instruments, as well as the mix
between sales of Kits and sales of Reagents and Components to collaborative
partners. The
 
                                      18
<PAGE>
 
Company is currently attempting to expand its diagnostic distribution channels
to include additional distributors of Kits on a non-exclusive basis, and the
Company further expects that current distributors of its Kits may increase
sales of their respective diagnostic tests incorporating the Company's
Reagents and Components.
 
  The Company's operating results have been impacted by the level of contract
revenues. The Company has recognized contract revenue from non-refundable fees
or milestone payments in support of its research and development efforts. The
level of contract revenues in future periods will depend primarily upon the
extent to which the Company enters into other collaborative contractual
arrangements, if any, and its achievement of milestones under current
arrangements. The Company does not anticipate significant contract revenues in
future periods.
 
  The Company has entered into agreements to support research at certain
research institutions. These agreements, which grant the Company licenses
and/or options to license certain technology resulting from the research,
generally require the Company to pay royalties to such institutions on the
sales of any products that utilize the licensed technology. Further, the
Company has licenses under certain patents, patent applications and technology
and pays the licensors or their licensees royalties under such agreements.
 
  All royalties are reflected in cost of sales as incurred. Royalty costs
represent a significant percentage of cost of sales. The Company expects cash
outflows related to such royalty arrangements to increase in future periods.
The Company expects to invest significant amounts in future periods for the
purchase of instruments and expansion of facilities. The Company's expenses
related to depreciation of such equipment and facilities is expected to
significantly increase in future periods. In addition, a significant amount of
the Company's expenditures are paid to Centocor pursuant to the Services
Agreement. See "Relationship with Centocor, Inc."
 
  The Company expects its research and development and sales and marketing
expenses to increase significantly related to the development and
commercialization of the P-selectin Profile. As a result of increased spending
on research and development and the expected initiation of commercialization
expenditures related to the Company's P-selectin Profile, the Company
anticipates incurring operating losses in 1998 and 1999.
 
  The Company's effective tax rate for the years ended December 31, 1994, 1995
and 1996 was 43%, 41% and 40%, respectively. For the nine-month periods ended
September 30, 1996 and 1997, the Company's effective tax rate was 41%.
Pursuant a Tax Sharing Agreement expected to be entered into with Centocor,
for as long as the Company is a member of Centocor's consolidated group for
federal income tax purposes, the Company will make no payments for its share
of the consolidated group's federal income tax liability to the extent that
the consolidated group's federal net operating loss and tax credit
carryforwards are available to offset consolidated taxable income. To the
extent that Centocor's net operating loss and tax credit carryforwards are no
longer available to shelter its consolidated group's taxable income, the
Company will then be required to make payments to Centocor for its portion of
the consolidated group's tax liability. Although the Company has reported a
provision for income taxes in all the periods presented, no tax payments were
payable because Centocor's consolidated group did not generate taxable income.
The benefit derived by the Company from inclusion in Centocor's consolidated
tax return has been reflected as a contribution to capital. In the event the
Company ceases to be a member of the Centocor consolidated tax group, the
Company will be subject to the payment of income taxes as a stand-alone
corporation.
 
 Nine months ended September 30, 1997 compared to nine months ended September
30, 1996
 
  Sales for the nine-month period ended September 30, 1997 were $24,191,000 as
compared to $28,574,000 for the same period in 1996. This decrease was due
primarily to a reduction in Reagent sales, lower Kit unit volumes and, to a
lesser extent, the unfavorable impact of foreign currency fluctuations.
 
  Costs of sales for the nine-month period ended September 30, 1997 was
$8,221,000 as compared to $10,329,000 for the same period in 1996. This
decrease was due primarily to lower sales during the period. The Company's
gross margins on sales was approximately 66% for the nine-month period ended
September 30, 1997 as compared to approximately 64% for the same period in
1996.
 
 
                                      19

  Marketing, general and administrative expenses were $8,773,000 for the nine-
month period ended September 30, 1997 as compared to $7,506,000 for the same
period in 1996. This increase was due primarily to increased market
development expenses related to the Company's cardiovascular program. The
levels of the Company's marketing, general and administrative expenses were
expected to increase in future periods as compared to 1997 levels as the
Company expands its market development activities in connection with new
cardiovascular products and directly undertakes the promotion, marketing and
sales of cardiovascular products.
 
 Year ended December 31, 1996 compared to year ended December 31, 1995
 
  Sales for the year ended December 31, 1996 were $37,611,000 as compared to
$40,208,000 for the same period in 1995. This decrease was due primarily to a
one-time $2,176,000 1995 stocking order of Reagents to a new customer and the
reduction in the percentage of end-user sales that the Company received from
the sale of Reagents in 1996 due to a change in certain exclusive arrangements
to non-exclusive in an effort to allow the Company to increase its market
penetration.
 
  Cost of sales for the year ended December 31, 1996 was $13,458,000 as
compared to $13,479,000 for the same period in 1995. The Company's gross
margin on sales for the year ended December 31, 1996 was approximately 64% as
compared to approximately 66% for the same period in 1995.
 
  Research and development expenses for the year ended December 31, 1996 were
$7,758,000 as compared to $5,336,000 for the same period in 1995. This
increase was due primarily to increased expenditures in the clinical area for
CA 15-3 (breast cancer). In addition, headcount-related expenses increased to
support development of new cardiovascular products and development of the
Company's cancer products on automated instruments partners' instrumentation
platforms.
 
  Marketing, general and administrative expenses for the year ended December
31, 1996 were $10,162,000 as compared $10,356,000 for the same period in 1995.
This decrease was due to lower allocations of administrative and facility
expenses to the Company, as Centocor increased its pharmaceutical-related
activities.
 
 Year ended December 31, 1995 compared to year ended December 31, 1994
 
  Sales for the year ended December 31, 1995 were $40,208,000 as compared to
$36,325,000 for the same period in 1994. This increase in sales was primarily
due to a one-time stocking order of Reagents to a new customer and an increase
in CA 15-3 sales resulting from the launch of the product on a new automated
instrument with one of the Company's automated instrument partners.
 
  Cost of sales for the year ended December 31, 1995 was $13,479,000 as
compared to $12,505,000 for the same period in 1994. This increase was
primarily due to increased unit volumes sold. The Company's gross margin on
sales for the years ended December 31, 1995 and 1994 was approximately 66%.
 
  Research and development expenses for the year ended December 31, 1995 were
$5,336,000 as compared to $6,531,000 for the same period in 1994. This
decrease was due primarily to lower clinical expenses for CA 15-3.
 
  Marketing, general and administrative expenses for the year ended December
31, 1995 were $10,356,000 as compared to $9,961,000 for the same period in
1994. This increase was primarily due to increased market development expenses
for the Company's oncology products line.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  At September 30, 1997, after giving pro forma effect to completion of the
offering (at an assumed public offering price of $    per share), the Company
would have had cash, cash equivalents and investments of approximately $   .
For the years ended December 31, 1994, 1995 and 1996, the Company generated
positive cash flow of, and distributed, $12,395,000, $10,959,000 and
$12,787,000, respectively, to Centocor. For
 
                                      20
<PAGE>
 
the nine months ended September 30, 1996, the Company generated positive cash
flow of, and distributed, $10,105,000 to Centocor. For the nine months ended
September 30, 1997, the Company distributed $1,036,000 to and received a
$2,000,000 capital infusion from Centocor. The Company expects to
significantly increase the level of capital expenditures for the purchase of
instruments and facility expansion in connection with the development of its
cardiovascular program. The Company expects that its cash reserves, including
the proceeds of this offering, will be sufficient to fund operations and such
capital expenditures for the foreseeable future.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
  In February 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, Earnings Per Share ("SFAS No. 128"). The statement replaces the
presentation of primary earnings per share ("EPS") with a presentation of
basic EPS. Basic EPS excludes dilution and is computed by dividing income
available to common stockholders by the weighted average number of common
shares outstanding for the period. SFAS No. 128 also requires dual
presentation of basic and diluted EPS on the face of the income statement and
other reconciliations and disclosures. The Company is required to adopt SFAS
No. 128 in its fiscal year ending December 31, 1997. Accordingly, the EPS
presentation herein does not reflect the presentation requirements of SFAS No.
128. There is no difference between the earnings per share calculated under
SFAS No. 128 and the earnings per share presented in the Company's
consolidated financial statements.

BACKGROUND
 
  Centocor Diagnostics develops, manufactures and sells diagnostic human
health care products based primarily upon monoclonal antibody technologies.
The Company's products and product candidates focus on disease categories with
large market potential, primarily in oncology and cardiovascular diseases. The
Company is a leading provider of in vitro (outside the body) diagnostic
("IVD") tests, components and reagents to monitor the efficacy of cancer
therapies, primarily in patients with breast, ovarian or pancreatic cancer.
 
  The Company is currently developing a point-of-care ("POC") cardiovascular
diagnostic test, the P-selectin Profile, designed to allow emergency room
physicians to rapidly and accurately rule in for further treatment patients
suffering Acute Coronary Syndrome ("ACS") and rule out for non-cardiac
treatment or early discharge patients not suffering ACS. The test is further
designed to determine whether patients suffering ACS are suffering a
myocardial infarction ("heart attack"), for whom immediate treatment is
critical to survival, or unstable angina ("UA"), for whom immediate or longer
term treatment is warranted. A heart attack is a condition where the heart
muscle is deprived of oxygen, usually due to the blockage of an artery,
resulting in irreversible heart muscle damage or potentially death. UA is
severe and constant pain and constriction about the heart caused by an
insufficient supply of blood to the heart. Current tests for a heart attack
include electrocardiograms ("ECGs"), which initially fail to diagnose one-half
of heart attack cases, and cardiac enzymes, which begin to detect a heart
attack only after irreversible damage to the heart muscle has occurred. Based
on patient trials conducted to date, the Company believes that the P-selectin
Profile offers a unique opportunity to improve the quality of care for ACS
patients by complementing existing ECG and cardiac enzyme technologies and to
reduce the costs of unnecessary testing and admissions for patients not
suffering ACS.
 
  Prior to the offering, the Company was a wholly owned subsidiary of
Centocor, a biopharmaceutical company with a primary focus in monoclonal
antibody technology. Centocor's leading product is ReoPro, a therapeutic drug
that is effective in preventing blood clotting by inhibiting the aggregation
of platelets. Anticoagulation agents such as ReoPro are used in the treatment
of cardiovascular diseases to prevent blood clots. The three main markets for
these agents are angioplasty, UA and heart attack. ReoPro is marketed and sold
in the U.S. and Europe for the reduction of acute ischemic cardiac
complications in patients who are at high risk for such events following
angioplasty. Centocor has filed for marketing approval of ReoPro for all
angioplasty patients and for UA patients who are not responding to current
treatment. Centocor is currently performing clinical trials to expand the
indications for use of ReoPro in heart attack patients.
 
  In connection with its development of the P-selectin Profile, the Company
benefits from extensive research, development and clinical data in the
cardiovascular field developed by Centocor in connection with its development
of ReoPro. The Company believes that the P-selectin Profile can be utilized as
an indicator of situations where ReoPro (and other platelet aggregation
inhibitors to the extent they become available) and thrombolytic (clot-
busting) drugs are effective as a therapeutic treatment.
 
INDUSTRY OVERVIEW
 
  IVD tests are primarily used to test patient blood samples to detect or
monitor disease. There are four basic technologies that are widely used
throughout the IVD industry: cell counting, clinical chemistry, microbiology
and immunoassay. All of the Company's existing products, and the P-selectin
Profile, are immunoassay-based tests. Such tests are performed primarily in
hospital and commercial laboratories.
 
  Immunoassay tests, which utilize antibodies for the detection of a
substance, were first developed based on technology developed in the 1960s.
Although early immunoassay tests offered unprecedented levels of sensitivity,
they suffered from relatively short shelf-lives, long reaction times, a need
for radioactive labels to detect completed reactions and lack of consistent
results among products from different suppliers. Over time, technological
advancements such as the introduction of monoclonal antibodies, enzyme and
fluorescent labels and various solid-phase mechanisms shortened immunoassay
test reaction times, provided higher specificity and allowed development of
tests with longer shelf-lives and greater consistency.
 
                                      22
<PAGE>
 
  Cardiovascular disease is the leading cause of death in the U.S. Heart
attacks alone accounted for approximately 21% of all deaths in the U.S. in
1994. Current IVD cardiovascular diagnostic tools, including coagulation tests
and cardiac enzyme markers, represented an approximately $1.0 billion
worldwide market in 1996. The Company believes there is significant potential
for growth in this area because current cardiovascular diagnostic tools are
unable to diagnose the occurrence of cardiac events in a large number of
patients in time for these patients to receive clinical benefit from
therapeutic interventions.
 
  Cancer is the second leading cause of death in the U.S., accounting for
approximately 24% of all deaths in 1996. The cancer segment of the worldwide
IVD market was approximately $780 million in 1995. The Company does not expect
this segment to grow significantly in the forseeable future. The Company's IVD
products were incorporated into tests that generated approximately $150
million of sales to hospitals and laboratories in 1996. In the Company's
target areas of breast, ovarian and pancreatic cancers, tests incorporating
the Company's products maintained a worldwide market share ranging from 80% to
90% during 1996.
 
  Factors that are critical to success in the IVD industry are a company's
ability to demonstrate the clinical efficacy of the diagnostic information
produced by, and the cost effectiveness of utilizing, its tests. The Company
believes that there is significant market potential for POC diagnostic tests,
such as the P-selectin Profile, which allows for rapid, accurate results. POC
testing can reduce the overall costs of health care delivery and improve
patient outcomes by ensuring correct and timely decision making and avoiding
unnecessary medical testing and admissions.
 
COMPANY STRATEGY
 
  The Company's strategy is to:
 
  Commercialize the P-selectin Profile. The Company intends to pursue growth
through the introduction of novel diagnostic products that address large
markets with unmet clinical and economic needs. The Company believes that the
P-selectin Profile fulfills these criteria. The Company's strategy for
successful introduction of the P-selectin Profile includes: (i) developing a
POC instrument system to perform the P-selectin Profile in the emergency room
that will allow ACS clinicians to receive rapid and accurate test results,
(ii) building a significant clinical database through a number of prospective
clinical trials staged over the next three years, including Centocor's Gusto
IV clinical trial of ReoPro scheduled to be initiated in 1998, to confirm the
performance of the P-selectin Profile and to obtain timely regulatory approval
from the FDA, (iii) utilizing clinical trial results and strong relationships
with leading ACS physicians to facilitate the P-selectin Profile's
incorporation into the U.S. national "Best Practices" chest pain management
protocol and (iv) developing a direct sales force to market the P-selectin
Profile and the POC instrument system in the U.S. The Company currently
expects to market the P-Selectin Profile in Europe and Japan through
partnering arrangements.
 
  Maintain a leading position in the cancer IVD test market. The Company's
existing IVD tests for monitoring the efficacy of cancer therapies, especially
those targeted for breast, ovarian and pancreatic cancers, enjoy strong market
positions and generate positive cash flow, which the Company expects to
utilize to support new initiatives such as the P-selectin Profile. The Company
intends to undertake initiatives to support these products to maximize their
market position and cash flow potential, including continuing to support the
evolution of automated IVD systems and expanding current geographic marketing
approvals.
 
  Continue to leverage unique relationship with Centocor. As a subsidiary of
Centocor, the Company realizes significant strategic and operating benefits
from a shared base of technology in monoclonal antibodies generally, and
specifically in the cardiovascular and oncology areas, research and
development skills and procedures, clinical trial management techniques and
data, the ability to have its product candidates included in Centocor's
clinical trials and common marketing activities within the same disease area
that are targeted to the same decision makers and institutions. In particular,
the Company believes that the opportunity for the P-selectin Profile to be
included with ReoPro in a cardiovascular disease management program offers
significant clinical and marketing benefits. Centocor Diagnostics is uniquely
positioned to benefit from the management systems and infrastructure in place
at Centocor.

CARDIOVASCULAR DIAGNOSTICS
 
  The Company is developing the P-selectin Profile, which it intends to
incorporate into a POC instrument system designed to provide rapid, accurate
test results to enable treating physicians to determine the appropriate
cardiovascular care for chest pain patients.
 
  In the U.S., approximately 6.0 million patients enter hospital emergency
departments each year complaining of chest pain. Of these, approximately
500,000 are immediately diagnosed as having a heart attack based on an ECG and
undergo emergency cardiac intervention. An additional 500,000 are ultimately
diagnosed as having had a heart attack based on tests that identify the
presence of cardiac enzymes and additional ECGs and undergo cardiac
intervention, although not before irreversible damage has occurred to the
heart muscle. Approximately 1.5 million are ultimately diagnosed with UA and
usually undergo long-term cardiac treatment and monitoring. The remaining 3.5
million are diagnosed as not having had a cardiac event and are treated for
non-cardiac conditions or are discharged. Unfortunately, approximately 35,000
of these 3.5 million patients are sent home with an undiagnosed heart attack,
and 6,000 of these patients die within 48 hours. These misdiagnoses account
for approximately 20% of all malpractice settlements paid by emergency
department doctors. In addition, approximately 2.1 million of these 3.5
million patients are diagnosed as not having had a cardiac event only after
extensive testing and hospital stays. National statistics indicate that
approximately $4.0 billion of unnecessary medical costs are spent each year on
these 2.1 million non-cardiac cases.
 
  The U.S. national "Best Practices" chest pain management protocol
promulgated by the AHA and the ACC strives to rule in chest pain patients
suffering ACS and, if necessary, to initiate reperfusion efforts (restoring
blood flow to the heart, whether by thrombolytic or other therapeutic drugs,
balloon angioplasty, by-pass surgery or other technique) within 30 minutes of
presentation to the emergency room. Under this protocol an ECG should be
performed within ten minutes of presentation. Unfortunately, only 50% of
patients actually suffering a heart attack are accurately diagnosed by the
initial ECG screen. Suspected heart attack patients whose ECG results are
inconclusive are given diagnostic tests to identify the presence of cardiac
enzymes, including CK, CK-MB, myoglobin, troponin-I and troponin-T. Cardiac
enzymes are markers of heart tissue death, confirming that cardiac damage has
taken place. Because cardiac enzymes do not elevate to detectable levels until
several hours after a heart attack, these tests are administered at three-hour
intervals following initial presentation, resulting in an average of four
tests being administered per patient. Although these tests cannot diagnose a
heart attack until irreversable damage has occurred, approximately $250
million of these cardiac enzyme tests are ordered annually in the U.S. by
physicians treating chest pain patients.
 
  Time is a critical factor in the treatment of heart attack patients. Within
two hours of the onset of a heart attack, more than 50% of the clinical
benefit possible from reperfusion is lost because permanent damage to the
heart muscle tissue has occurred. Reducing the time necessary to diagnose
accurately a patient suffering from a heart attack provides a significant
opportunity to improve the standard of care and outcomes of those patients.
 
  Even if a patient is not suffering a heart attack, it is important to
determine whether chest pain patients are suffering from another
cardiovascular disease, such as UA or angina. UA patients have wide degrees of
risk, with high-risk UA patients having the same morbidity and mortality rates
after three and six months as heart attack patients. There is no test
currently available to emergency room physicians that can quickly identify UA
or angina patients or risk-stratify these patients to appropriate levels of
care.
 
  To significantly improve ACS patient quality of care and outcomes, while
reducing the cost to manage chest pain patients, clinicians need diagnostic
information that will enable them to rapidly rule in heart attack and UA
patients not identified by ECGs, rapidly rule out non-cardiac patients and
avoid discharging high-risk patients.
 
 P-selectin Profile
 
  Most cardiac events result from years of plaque buildup. A rupture of this
plaque exposes subendothelial cells of the blood vessels to platelets, which
initiates platelet activation. As more platelets activate,
 
                                      24
<PAGE>
 
they begin to aggregate, forming a hemostatic plug, or clot. As this clot
grows, the heart is deprived of needed oxygen and blood flow, frequently
resulting in a heart attack or UA.
 
  P-selectin is a protein that is exposed on the platelet membrane when
platelets become activated and the expression of this protein remains elevated
for up to two hours after activation. P-selectin is also shed from the
platelet and becomes elevated in the blood plasma for up to twelve hours after
platelet activation. After studying the predictive value of individual assays
for platelet-bound and plasma-based P-selectin in more than 2,200 samples, the
Company developed the P-selectin Profile, which measures the status of
platelet-bound and plasma-based P-selectin, as a method of assessing platelet
activation, an early indicator of ACS. In human clinical proof-of-principle
studies, preliminary data indicates that the P-selectin Profile has a high
predictive value for identifying patients with ACS. For the heart attack
cases, the P-selectin Profile was performed when the patients presented at the
emergency department and the results were compared to the eventual clinical
diagnosis. Of the 30 heart attack patients enrolled to date, the P-selectin
Profile was positive on 28 (93%). Of 60 normal control subjects tested, 57
(95%) were P-selectin Profile negative. The results of cardiac enzyme tests
were negative on all of these patients upon presentation.
 
  Initially, the Company believes that the P-selectin Profile will
significantly improve patient quality of care and outcomes, while reducing the
cost to manage chest pain patients. Because the P-selectin Profile is designed
to provide treating physicians with rapid, accurate diagnostics results to
permit appropriate cardiovascular care for chest pain patients, the Company
believes that the P-selectin Profile, if successfully developed, could be
administered to each of the approximately 6.0 million chest pain patients who
enter U.S. hospital emergency rooms each year. By providing accurate and
timely diagnostic results, the P-selectin Profile will enable clinicians to
(i) rapidly rule in for treatment the 500,000 patients who are suffering a
heart attack but whose initial ECG was inconclusive, and those patients who
are suffering a heart attack but, because of the present lack of a reliable
cardiovascular diagnostic test, are sent home, (ii) rapidly rule in for
treatment the 1.5 million patients that are suffering from UA and (iii)
rapidly rule out the 3.5 million patients who do not have a cardiac condition.
The Company believes that the P-selectin Profile can be further developed in
other areas, such as assisting clinicians in properly risk-stratifying UA
patients and monitoring the utility of thrombolytic or platelet-blocking
therapeutic treatments and interventions.
 
  The Company will concentrate on four areas for the commercialization of the
P-selectin Profile: (i) development of a POC instrument system, (ii) execution
of a regulatory strategy, utilizing well-designed clinical trials, for
obtaining timely FDA regulatory approval, (iii) incorporation of the P-
selectin Profile into the U.S. national "Best Practices" chest pain management
protocol and (iv) development of a direct sales force to market the P-selectin
Profile and the POC instrument system in the U.S.
 
  Point-of-Care Instrument System. The U.S. national "Best Practices" chest
pain management protocol specifies 30 minutes from patient presentation to
therapy initiation. To meet this specified time frame, the P-selectin Profile
must be performed on an instrument system that is able to perform both the
membrane-bound and plasma-based P-selectin tests in the emergency room rather
than in a hospital's central laboratory. Existing diagnostic instruments are
not able to perform these tests simultaneously, in an emergency room setting
or within the required 30-minute time frame. Currently, performing the
membrane-bound and plasma-based P-selectin tests requires approximately three
hours on conventional flow cytometry and enzyme immunoassay equipment. The
Company has entered into a collaborative arrangement with Biometric Imaging,
Inc. ("Biometric") to modify an existing instrument platform, consisting of a
computer-controlled, laser-based, static cytometry imaging system, for use as
a POC instrument system designed to deliver the full utility of the P-selectin
Profile. Biometric's existing instrument has received FDA clearance and is
used in measuring CD-4 and CD-8 cell counts in HIV patients. Collaborative
research performed with Biometric has preliminarily shown that the instrument
is capable of being adapted to perform both the membrane-bound and plasma-
based P-selectin tests simultaneously within 30 minutes. The Company has
exclusive rights to the Biometric instrument for use in in vitro
cardiovascular diagnostics applications.
 
  Clinical Trials and Regulatory Approval. The development of an extensive
database of clinical trial information to confirm the performance of the P-
selectin Profile and to assist in obtaining prompt regulatory
 
                                      25
<PAGE>
 
clearance is key to the Company's P-selectin Profile strategy. The Company
will seek regulatory clearance for the P-selectin Profile in three steps. It
will first seek 510(k) clearance for clinical laboratory versions of the
membrane-bound and plasma-based P-selectin Profile assays by comparing the
results from these tests with the results from conventional cardiovascular
diagnostics such as ECGs and cardiac enzyme tests. Next, it will seek
clearance for these assays performed on the Biometric instrument modified to
read the membrane-bound and plasma-based P-selectin tests simultaneously.
Finally, it will seek 510(k) clearance for the POC instrument being developed
by Biometric.
 
  The Company has initiated a prospective trial, MAPS (Management of Acute
Coronary Syndromes with P-selectin Profile), which consists of a three-site
pilot to be followed by a ten-site trial with an aggregate of approximately
1,300 patients. The Company anticipates enrolling patients in the MAPS trial
in early 1998. The MAPS trial will be the first large-scale study on all chest
pain patients to determine the performance of the P-selectin Profile. Patients
presenting to the emergency department with chest pain will be evaluated at
zero, three, six, nine and twelve hours following onset of chest pain. The
results from the P-selectin Profile will be compared to the results from
conventional cardiovascular diagnostics such as ECGs and cardiac enzyme tests
as well as the clinical diagnosis of heart attack, UA, and non-cardiac events.
Outcomes will be captured at discharge, at 30 days and six months. Pilot phase
data, which will consist of data through discharge from 300 patients at three
sites, is expected to be available in 1998. The MAPS pilot phase will use
clinical laboratory versions of the assays for the membrane-bound and plasma-
based tests to develop data to be submitted to FDA seeking initial 510(k)
clearance of the P-selectin Profile.
 
  In addition, the P-selectin Profile will be included in a substudy of
Centocor's Gusto IV clinical trials for ReoPro for expanded indications in
heart attacks and UA. The Company believes that its ability to include the P-
selectin Profile in Centocor's ReoPro clinical trials provides the Company
with a distinct advantage over competitors who may be developing products that
may compete with the P-selectin Profile. This trial will include an additional
2,000 patients. The MAPS trial, and the ReoPro Gusto IV substudy will use a
version of the Biometric instrument system that will be modified to read the
membrane-bound and plasma-based P-selectin tests simultaneously. The Company
expects that data from these studies will result in a 510(k) filing to the FDA
for the P-selectin Profile on the Biometric instrument, as modified.
 
  Finally, the Company expects to perform an equivalency study on 1,000
patients at ten sites to demonstrate that the P-selectin Profile as performed
on the final POC instrument system is equivalent to the performance of the
instrument system utilized in the MAPS and Gusto IV substudy. No assurances
can be given that data from the MAPS or Gusto IV substudy will be available on
the Company's anticipated schedule, that such data will support the
sensitivity or specificity of the P-selectin Profile or the Biometric
instrument system or that such data will support 510(k) filings with the FDA.
 
  Incorporation into "Best Practices" Chest Pain Management Protocol. Chest
pain patient management is highly protocol driven. A small group of
influential decision makers impact a large portion of the market by setting
the national "Best Practices" chest pain management protocol for patients with
chest pain promulgated by the AHA and the ACC. Through Centocor's experience
with ReoPro in the cardiovascular field, the Company has developed strong
relationships with many of these protocol developers, and certain of these
persons are scientific advisors to the Company or among the lead investigators
for the Company's P-selectin Profile clinical trials. The Company believes
that these established relationships will help position the Company to
communicate its findings and supporting data from the clinical trials of the
P-selectin Profile and the POC instrument system to those most influential in
setting national "Best Practices" chest pain management protocol.
 
  Marketing of the P-selectin Profile. The Company intends to position the P-
selectin Profile for use as a complement to the ECGs and cardiac enzyme tests
that are administered to chest pain patients presenting themselves to hospital
emergency rooms. Existing chest pain management protocol provides for an
initial ECG test to be performed within ten minutes after presentation and for
cardiac enzyme tests to be administered every three hours, resulting in an
average of four tests being administered per patient. In addition, chest pain
patient activity is highly concentrated, with approximately 20% of the
hospitals in the U.S. treating more than 50% of heart attack patients. This
concentration will allow the Company to focus its cardiovascular marketing
resources.
 
                                      26
<PAGE>
 
The Company currently expects to market the P-selectin Profile and the POC
instrument system in the U.S. through its own direct sales force. The
Company's direct sales force will market and provide support for the P-
selectin Profile and the POC instrument system to substantially all of the 20%
of hospitals treating the majority of chest pain patients. The Company may
also supplement its direct sales force in the U.S. and market the P-selectin
Profile outside the U.S. through marketing arrangements with one or more large
pharmaceutical companies that have extensive experience marketing products for
use in emergency rooms.
 
  The Company believes that the P-selectin Profile can be utilized as an
indicator of situations where ReoPro (and other platelet aggregation
inhibitors to the extent they become available) is effective as a therapeutic
treatment. ReoPro is currently approved for patients who are at high-risk for
abrupt artery closure following angioplasty and is currently being marketed by
Eli Lilly and Company. Centocor has filed two amendments to its ReoPro Product
License Application ("PLA") to include the treatment of all angioplasty and UA
patients who are not responding to current treatment.
 
  While the initial focus for the P-selectin Profile is to provide timely
diagnostic information to clinicians treating chest pain patients, the Company
intends to expand the uses of the P-selectin Profile in other areas, such as
the need for diagnostic information to support ACS therapeutic treatment.
There are currently two categories of drugs that are used to treat ACS,
platelet aggregation inhibitors such as ReoPro and thrombolytics, which are
clot-busting drugs that break up fibrin accumulation. Current clinical trials
by Centocor are focused on managing ACS patients through a combination of both
types of therapeutics. The Company believes that the P-selectin Profile, which
has preliminarily been found to measure platelet activation accurately, in
conjunction with fibrin markers under development by the Company, may provide
important complementary information to clinicians managing patients with such
a drug combination.
 
  In addition, the Company believes that the P-selectin Profile may be
modified for use as a diagnostic tool to measure platelet function management
that may allow the P-selectin Profile to become integrated into the protocol
of hospital departments, in addition to the emergency room, where patients
undergo ACS care including the chest pain emergency room, cardiac care unit,
catheterization lab and cardiovascular operating room. To facilitate
acceptance of the P-selectin Profile outside of the emergency room, the
Company expects to partner with leading manufacturers of instruments used in
these other hospital departments, with the goal of incorporating the
P-selectin Profile into existing instrument platforms.
 
  The Company also believes that the P-selectin Profile can be refined to
assist emergency room doctors risk stratify UA patients. Approximately 1.5
million of the 6.0 million patients who present themselves to emergency rooms
with chest pain annually in the U.S. are eventually diagnosed with UA and
undergo some type of therapy. These UA patients have wide degrees of risk,
with high-risk UA patients having the same morbidity and mortality rate after
three and six months as heart attack patients. Since there is no diagnostic
tool currently available to clinicians to properly risk-stratify UA patients
to appropriate levels of care, further development of the P-selectin Profile
to perform this function would satisfy an unmet need in the management of UA
patients.
 
 ARRANGEMENTS WITH BIOMETRIC IMAGING
 
  The Company has entered into an agreement with Biometric dated October 9,
1997, (the "Development Agreement"), pursuant to which Biometric is obligated
to complete the tasks necessary to develop the POC instrument system by
modifying its existing IMAGN 2000 instrument system so that it performs both
the membrane-bound and plasma-based P-selectin tests simultaneously. Pursuant
to the Development Agreement and a related Stock Purchase Agreement, Centocor
has made an equity investment of $2,000,000 in Biometric and will make
additional equity investments of up to $2,000,000 based on Biometric's
successful completion of stated performance milestones. Under the Development
Agreement, the Company is obligated to perform certain development of the
existing assays that will be incorporated into the P-selectin Profile. Under
the Development Agreement, Biometric has granted the Company an exclusive,
worldwide license to use Biometric's technology and intellectual property to
make POC instrument systems and the related tests for in vitro diagnostic
procedures for the detection of cardiovascular events. Biometric holds five
U.S. patents covering Biometric's instrument
 
                                      27

platform and has one U.S. patent pending. Upon commercialization, the Company
will pay Biometric a percentage of the Company's cumulative net sales of the
P-selectin Profile, which percentage will decline as net sales increase.
 
ONCOLOGY DIAGNOSTICS BUSINESS
 
  Approximately 7.4 million people in the U.S. presently have a history of
invasive cancer and 1.4 million new cases are diagnosed each year. Early
detection and assessment of the stage of the cancer offers the greatest
potential for diagnostic information to affect the long-term survival and
reduced cost of treating cancer patients.
 
IVD TESTS
 
  From their initial commercialization in 1982, the Company has built strong
product franchises in the area of IVD tests for monitoring of the efficacy of
cancer therapies. The Company's monoclonal antibodies that are utilized in
these tests are unique, highly specific proteins that detect the presence of
specific antigens, which are produced by cancer cells.
 
  The Company presently makes its IVD tests available to its distributors and
automated instrument partners in three basic forms:
 
    Bulk reagents for kits. These are the key raw materials, including the
  Company's antibodies, which are used by kit and automated systems
  manufacturers who purchase the raw materials for inclusion in their own
  finished test.
 
    Components for automated systems. These are components for automated
  systems that include the Company's antibodies and other reagents. These are
  integrated by the customer with other components to produce a finished test
  for use on the automated system.
 
    Completed kits. These are finished test kits in a form that is ready to
  be used by a testing lab.
 
  The following table summarizes the IVD tests currently marketed by the
Company:

</TABLE>
 
  The Company has distribution agreements with global and regional
distributors with established networks who sell the Company's completed kits
to hospitals and clinical and research testing laboratories. The Company's
completed kits are marketed and sold by the Company's distributors. The
Company's components for automated systems are sold by the Company's automated
instrument partners. The Company's tests are compatible with more than 90% of
all diagnostic automated systems instruments, including those of Abbott
Laboratories, Roche Diagnostic Systems, Inc., Ortho Clinical Diagnostics, Inc.
(a division of Johnson & Johnson, Inc.), Bayer Corporation and Pasteur Sanofi
Diagnostics.
 
  The Company's IVD tests are well-positioned within each of the areas of
cancer targeted by the tests. In the Company's target areas of breast, ovarian
and pancreatic cancers, tests incorporating the Company's products maintained
a worldwide market share ranging from 80% to 90% during 1996.
 
  During 1996, approximately 64% of the Company's IVD tests were sold in
Europe, while approximately 25% and 11% were sold in Japan and the U.S.,
respectively. The Company's CA 125 II kit has been cleared for marketing in
the U.S. since 1987. The Company recently received marketing clearance for its
completed CA 15-3 kits in the U.S. and anticipates seeking marketing clearance
of its completed CA 19-9 kits in the U.S. Additional marketing clearance will
be necessary prior to commercialization in the U.S. by the Company's automated
instrument partners of IVD tests incorporating the Company's components or
bulk reagents, including CA 15-3 and CA 19-9.
 
  In 1996, the Company's IVD tests accounted for approximately $38 million in
revenues for the Company. Peak revenue for these products was approximately
$42 million in 1993. Since then, revenues have ranged
 
                                      28
<PAGE>
 
between $37 and $40 million annually. A shift in the product mix from
completed kits to components for automated systems and bulk reagent sales have
resulted in average unit price declines in excess of volume growth. The
Company expects that this shift in product mix will continue over the next few
years. However, the Company believes that the decrease in revenues from the
shift in product mix will be offset by increases in volume growth for these
products, especially as products incorporating the Company's IVD tests receive
further regulatory approval worldwide.
 
PROPRIETARY TECHNOLOGY, PATENTS AND LICENSES
 
  Products currently being marketed, developed or considered for development
by the Company are in the area of biotechnology, an area in which there are
extensive patent filings. The patent position of biotechnology companies
generally is highly uncertain and involves complex legal and factual
questions. To date, no consistent policy has emerged regarding the breadth of
claims allowed in biotechnology patents. Accordingly, there can be no
assurance that patent applications owned or licensed by the Company will
result in patents being issued or that, if issued, such patents will afford
protection against competitors with similar technology. In addition, there can
be no assurance that products covered by such patents, or any other products
developed by the Company or subject to licenses acquired by the Company, will
not be covered by third party patents, in which case continued development and
marketing of such products would require a license under such patents. There
can be no assurance that such required licenses will be available to the
Company or its licensees on acceptable terms.
 
  Other entities have filed applications for or have been issued patents and
are expected to obtain additional patents to which the Company may need to
acquire rights. The extent to which the Company may need to obtain rights to
any such patents or to contest their scope or validity will depend on final
product formulation and other factors. The ability to license any such patents
and the likelihood of successfully contesting the scope or validity of such
patents are uncertain and the costs associated therewith may be significant.
If the Company is required to acquire rights to valid and enforceable patents
but cannot do so at a reasonable cost, the Company's ability to manufacture or
market its products in the country of issuance of any such patent may be
materially adversely affected.
 
  There has been substantial litigation regarding patent and other
intellectual property rights in the biotechnology industry. Litigation may be
necessary to enforce certain intellectual property rights of the Company. Any
such litigation could result in substantial cost to and diversion of effort by
the Company.
 
  Centocor Diagnostics currently licenses the majority of the cell lines used
to produce its monoclonal antibodies from research institutions pursuant to
long-term licenses for which it is generally obligated to pay royalties based
upon sales of products incorporating such antibodies. There can be no
assurance that others will not acquire rights to such cell lines in the
future.
 
  The Company has filed a U.S. patent application relating to certain methods
of determining endogenous platelet activation state and for determining the
effects of an anti-platelet agent, such as a glycoprotien IIb/IIIa antagonist,
on platelet activation state by assessing the levels of membrane-bound and/or
plasma-based P-selectin in a sample from an individual. The Company has also
filed a U.S. patent application directed to a method of diagnosing whether a
symptomatic patient has or does not have a thrombotic event, such as a heart
attack or stroke, employing a dual assay that yields a P-selectin profile. The
Company intends to seek international patent protection for these inventions
as well.

COMPETITION
 
  The health care industry is intensely competitive, and the Company expects
it to remain so for the foreseeable future. This level of competition is
reinforced at each stage of the IVD business: research, analyte developers,
instrumentation/system companies, distributors, hospital/clinical laboratories
and healthcare providers.
 
  Currently the majority of diagnostic tests are performed in hospital and
clinical laboratories. The impetus to move these tests to new, POC testing, or
to shift the mix between a hospital and clinical site, will be fiercely
resisted by these laboratories. There can be no assurance that the Company's
new products that require a change in testing site (POC, home testing) will be
able to compete against these entrenched competitors.
 
  The diagnostic industry is currently dominated by large, automated systems
suppliers with a broad product offering and significant market presence,
including Abbott Laboratories, Roche Diagnostic Systems, Inc. and Ortho
Clinical Diagnostics, Inc. These companies are vigorously competing for market
position, which results in strong price pressure and increasing consolidation
through mergers. These competitors all have substantially greater financial
resources, technical and research facilities, marketing and sales departments,
distribution and service organizations than the Company. In addition, these
competitors have broader product lines, established brand positions and
stronger customer relationships than the Company. While the Company's strategy
of partnering with these companies to incorporate the Company's products on
automated instruments presently utilizes these dominant market positions to
the Company's advantage, there can be no assurance that these competitors will
not be able to improve the performance of their existing product offerings to
effectively compete, or will not succeed in developing new technology and
products that will make the Company's products obsolete. In addition, there
can be no assurance that these competitors will not be able to use their
financial and market presence to limit or interfere with the ability of the
Company to sell its products.
 
  The Company believes that its strong competitive position in these cancer
areas is due to the IVD tests' proven historic product performance and the
cumulative supporting clinical utility data. Many peer-reviewed articles have
been published on the performance of the antibodies, and competitors would
face a significant barrier to entering into attempting to replicate the
supporting data available regarding the Company's IVD tests. In addition,
clinicians are resistant to adopt a new baseline standard for a diagnostic
test, creating a further barrier to competitive entry.
 
  The diagnostics industry is also characterized by a large number of small,
technology-based enterprises that are seeking to develop and exploit novel
technologies. While many of these companies have fewer financial and technical
resources than the Company, and do not have established positions in the
market, the sheer number of them and the broad array of technologies that they
are attempting to develop present a potential threat. The Company cannot
assure that these companies will not be able to develop breakthrough
technology whose performance capabilities will make the Company's products
obsolete.
 
GOVERNMENT REGULATION
 
  The preclinical and clinical testing, manufacturing, labeling, sale,
distribution and promotion of the Company's products are subject to extensive
and rigorous government regulation in the U.S. and other countries.
Noncompliance with applicable requirements can result in enforcement action by
the FDA including fines, injunctions, civil penalties, recall or seizure of
products, total or partial suspension of production, failure of the government
to grant premarket clearance or approval for devices, withdrawal of marketing
clearance or approval, and criminal prosecution.
 
  Most medical devices may be marketed in the U.S. only with the FDA's prior
authorization. Devices classified by the FDA as posing less risk are placed
either in Class I or II and require the manufacturer to seek 510(k) clearance
from the FDA prior to marketing. Such clearance generally is granted when
submitted information establishes that a proposed device is "substantially
equivalent" in intended use and safety and effectiveness to a "predicate
device," which is either a Class I or II device already legally on the market
or a "preamendment" Class III device (i.e., one that has been in commercial
distribution since before May 28, 1976)
 
                                      30
<PAGE>
 
for which the FDA has not called for PMA applications. The Company believes
that it usually takes from four to twelve months from the date of submission
to obtain 510(k) clearance, but it may take longer, and there can be no
assurance that any 510(k) submission will ever receive clearance. During this
process, the FDA may determine that it needs additional information or that a
proposed device is precluded from receiving clearance because it is not
substantially equivalent to a predicate device. After a device receives
clearance, any modification that could significantly affect its safety or
effectiveness, or would constitute a major change in the intended use of the
device, will require a new 510(k) submission.
 
  A device that does not qualify for 510(k) clearance is placed in Class III,
which is reserved for devices classified by the FDA as posing the greatest
risk (e.g., life-sustaining, life-supporting or implantable devices, or
devices that are not substantially equivalent to a predicate device). A Class
III device generally must obtain PMA approval, which requires proving the
safety and effectiveness of the device to the FDA. A PMA application must
provide extensive preclinical and clinical trial data and also information
about the device and its components regarding, among other things,
manufacturing, labeling and promotion. As part of the PMA review, the FDA will
inspect the manufacturer's facilities for compliance with the QSR.
 
  Upon submission the FDA determines if the PMA application is sufficiently
complete to permit a substantive review, and, if so, the application is
accepted for filing. The FDA then commences an in-depth review of the PMA
application, which the Company believes typically takes 1 to 3 years, but may
take longer. The review time is often significantly extended as a result of
the FDA asking for more information or clarification of information already
provided. The FDA also may respond with a "not approvable" determination based
on deficiencies in the application and require additional clinical trials that
are often expensive and time consuming and can delay approval for months or
even years. During the review period, an FDA advisory committee, typically a
panel of clinicians, likely will be convened to review the application and
recommend to the FDA whether, or upon what conditions, the device should be
approved. Although the FDA is not bound by the advisory panel decision, the
panel's recommendation is important to the FDA's overall decision making
process.
 
  If the FDA's evaluation of the PMA application is favorable, the FDA
typically issues an "approvable letter" requiring the applicant's agreement to
specific conditions (e.g., changes in labeling) or specific additional
information (e.g., submission of final labeling) in order to secure final
approval of the PMA application. Once the approvable letter is satisfied, the
FDA will issue a PMA for the approved indications, which can be more limited
than those originally sought by the manufacturer. The PMA approval can include
postapproval conditions that the FDA believes necessary to ensure the safety
and effectiveness of the device including, among other things, restrictions on
labeling, promotion, sale and distribution. Failure to comply with the
conditions of approval can result in material adverse enforcement action,
including the loss or withdrawal of the approval. The PMA process can be
expensive and lengthy, and no assurance can be given that any PMA application
will ever be approved for marketing. Even after approval of a PMA, a new PMA
or PMA supplement is required in the event of a modification to the device,
its labeling or its manufacturing process.
 
  The PDP process is an alternative to the PMA process for Class III devices.
It consists of two major steps. First, a proposed PDP is submitted to the FDA
providing extensive information about how the device would be developed,
tested and marketed. Among other things, the proposed PDP must provide
information describing: the device and modifications that may be made to it,
preclinical testing, clinical testing, manufacturing methods, facilities and
controls, any applicable performance standards and proposed labeling. The FDA
is required to seek advisory panel review of the proposed PDP. Approval of the
PDP requires the FDA to determine that the PDP is appropriate to determine
safety and effectiveness in lieu of the PMA process. If the FDA approves the
PDP, the second step requires submission of a notice of completion of the PDP
by the device sponsor, explaining how the PDP has been fulfilled and setting
forth the results of the testing and trials required by the PDP. If the FDA
finds that the PDP has been complied with and the device has been shown safe
and effective as labeled, the agency will issue an order declaring the PDP
completed. An order of completion permits the device to be marketed.
 
  The PDP process has been dormant during the past twenty years. The FDA only
recently has sought to revive it as an alternative to the PMA process that
could shorten the time to approval without reducing the overall
 
                                      31
<PAGE>
 
assurance of safety and effectiveness. In light of the FDA's lack of
experience with the PDP process, there can be no assurance that the PDP
process will reduce the time to approval as compared to the PMA process, and
no assurance can be given that any PDP will be approved or, if approved, that
a notice of completion will be obtained.
 
  The Company intends to pursue 510(k) clearance for its cardiovascular
products, which are intended for the measurement of the P-selectin antigen.
Tests for P-selectin have not been formally classified by the FDA and the
Company is not aware of any other P-selectin tests that have received 510(k)
clearance upon which to base a claim of substantial equivalence. The Company
will therefore seek to compare its tests for new analytes by demonstrating
substantial equivalence to other legally marketed Class I or II tests. In
discussions with the FDA representatives, the Company has been told that
510(k) review for the P-selectin assays is likely. However, no assurance can
be given that the FDA will not determine that the Company's cardiovascular
products must adhere to the PMA or PDP approval processes. Furthermore, no
assurance can be given that any of the cardiovascular products will receive
510(k) clearance in a timely fashion, or at all. Delays in market introduction
resulting from the 510(k) clearance process could have a material adverse
impact on the Company.
 
  The majority of the Company's oncology products are intended for use to
monitor treatment and disease progression in cancer patients. In September of
1996, the FDA reclassified the Company's monitoring tests from class III to
Class II, which makes them eligible for the 510(k) clearance process. Products
used for diagnosis, screening or detection of cancer have not been
reclassified and remain in Class III, which requires PMA approval or PDP
completion. Some of the Company's oncology products are or could be intended
for diagnosis or detection of cancer and would, therefore, remain in Class
III. There can be no assurance that a PMA application will be submitted for
any of these products or that, once submitted, the PMA application will be
accepted for filing, found approvable, or, if found approvable, will not take
longer than expected to obtain or include unfavorable restrictions. The
Company intends to submit a PDP rather than a PMA for its CA 19-9 oncology
product for diagnosis of pancreatic cancer. The submission would be among the
first to undergo the newly revived PDP procedure. There can be no assurance
that this PDP will be approved or that, if approved, the Company will be able
to complete it in a timely fashion or at all.
 
  The Company has made modifications to its cleared products which the Company
believes do not require the submission of new 510(k) notices. There can be no
assurance, however, that the FDA would agree with any of the Company's
determinations not to submit a new 510(k) notice for any of these changes or
would not require the Company to submit a new 510(k) notice for any of the
changes made to the product. If the FDA requires the Company to submit a new
510(k) notice for any product modification, the Company may be prohibited from
marketing the modified product until the 510(k) notice is cleared by the FDA.
 
  A clinical trial in support of a 510(k) submission or PMA application
generally requires an IDE application approved in advance by the FDA for a
limited number of patients and supported by appropriate data, such as animal
and laboratory testing results. However, clinical investigations of in IVD
tests are exempt from the IDE requirements, including the need to obtain the
FDA's prior approval, provided the testing is noninvasive, does not require an
invasive sampling procedure that presents a significant risk, does not
intentionally introduce energy into the subject, and is not used as a
diagnostic procedure without confirmation by another medically established
test or procedure. In addition, the IVD must be labeled for research use only
("RUO") or investigational use only ("IUO"), and distribution controls must be
established to assure that IVDs distributed for research or clinical
investigation are used only for those purposes. The FDA's current policy
encourages manufacturers who distribute IVDs on an RUO or IUO basis
voluntarily to establish a certification program under which the recipients
provide written certification that the IUO or RUO product will be restricted
in use and also that the recipient will comply with the other FDA requirements
(such as obtaining institutional review board approval and the informed
consent of patients).
 
  The Company is conducting investigations of its cardiovascular, ovarian
cancer detection and some of its oncology products, which involves
distributing them in the U.S. on an IUO or RUO basis. The Company has not
established a voluntary certification program. There can be no assurance that
the FDA would agree that the
 
                                      32
<PAGE>
 
Company's IUO/RUO distribution of these products meets IDE requirements.
Failure by the Company or the recipients of these products to maintain
compliance with these requirements could result in enforcement action by the
FDA, including, among other things, the loss of the IDE exemption or other
restrictions on distribution of these investigational products that could
adversely affect the Company's ability to conduct the clinical investigations
necessary to support marketing clearance or approval.
 
  Purchasers of the Company's clinical diagnostic products in the U.S. may be
regulated under CLIA and related federal and state regulations, which provide
for regulation of laboratory testing. These regulations impose quality
control, proficiency testing, personnel standards and federal inspections
requirements. Diagnostic tests are categorized under CLIA as "waived,"
"moderately complex," or "highly complex," on the basis of specific criteria.
If a product is placed in the "high complexity" category under CLIA
regulations, its use generally is limited to larger hospital and clinical
reference laboratories. The majority of the company's cardiovascular, ovarian
and oncology products have or likely will be categorized as high complexity
assays under CLIA. There can be no assurance that future CLIA regulations and
administrative interpretations will not further limit the potential market for
the Company's products, which could have a material adverse impact on the
Company.
 
  Some clinical laboratories purchase individual reagents intended for
specific analytes, which they use to develop and prepare their own finished
diagnostic tests (sometimes called "home brews"). The FDA generally has not
exercised regulatory authority over these individual reagents or the finished
tests prepared from them by clinical laboratories. In March 1996, however, the
FDA proposed new rules for analyte specific reagents ("ASRs") that would apply
a regulatory framework to them, including restrictions on promotional claims
that could be made about these products and restrictions on sales to clinical
laboratories certified under CLIA as high complexity testing laboratories. The
Company sells a number of individual reagents that would fall within the ASR
regulatory framework including antibodies and antigens for all of its oncology
products.
 
  Any devices manufactured or distributed by the Company pursuant to FDA
clearances or approvals are subject to pervasive and continuing regulation by
the FDA and certain state agencies. The Company is subject to routine
inspection by the FDA and must comply with the host of regulatory requirements
that usually apply to medical devices marketed in the U.S., including labeling
regulations, the QS Reg., MDR regulations, and the FDA's prohibitions against
promoting products for unapproved or "off-label" uses. In addition, Class II
devices can be subject to additional special controls (e.g., performance
standards, postmarket surveillance, patient registries, and FDA guidelines)
that do not apply to Class I devices. The Company's failure to comply with
applicable regulatory requirements could result in enforcement action by the
FDA, which could have a material adverse effect on the Company.
 
  Unanticipated changes in existing regulatory requirements, failure of the
Company to comply with such requirements or adoption of new requirements could
have a material adverse effect on the Company. The Company also is subject to
numerous federal, state and local laws relating to such matters as safe
working conditions, manufacturing practices, environmental protection, fire
hazard control and hazardous substance disposal. There can be no assurance the
Company will not be required to incur significant costs to comply with such
laws and regulations in the future or that such laws or regulations will not
have a material adverse effect upon the Company's business, financial
condition and results of operations.
 
EMPLOYEES
 
  As of September 30, 1997, the Company had approximately 130 full-time
employees engaged in administration, operations, research and development and
sales and marketing. To complement its own expertise in various fields,
Centocor Diagnostics utilizes scientific consultants and other advisors, many
of whom have formal consulting agreements with the Company.
 
                                      33

FACILITIES AND MANUFACTURING
 
  The Company occupies approximately 50,000 square feet of space in three
buildings in Malvern, Pennsylvania that it leases from Centocor, Inc. These
buildings contain the Company's corporate offices, research and development
laboratories, marketing offices, and manufacturing facilities. The
manufacturing facility for the production and filling of monoclonal antibody-
based products is subject to inspection by the FDA, complies with QSR
requirements and is ISO 9001 certified. In addition to its own products, the
Company also provides contract manufacturing services to diagnostic and
pharmaceutical companies in need of this specialized capability. The Company
has approximately 60 people engaged in these manufacturing operations at
Malvern.
 
LEGAL PROCEEDINGS
 
  The Company is not currently a party to any litigation that it believes
would materially affect the Company's business, financial condition or results
of operations.

                       RELATIONSHIP WITH CENTOCOR, INC.
 
  The Company is currently a wholly owned subsidiary of Centocor. Upon
completion of the offering, Centocor will own 100% of the Company's
outstanding Class B Common Stock (    shares), which will represent
approximately   % of the outstanding Common Stock of the Company
(approximately   % if the Underwriters' over-allotment option is exercised in
full) and approximately   % of the combined voting power of the Company's
outstanding Common Stock (approximately   % if the Underwriters' over-
allotment option is exercised in full) and thus will continue to have the
ability to elect all of the directors of the Company and otherwise exercise a
controlling influence over the business and affairs of the Company.
 
  For as long as Centocor continues to own shares of Class B Common Stock
representing more than 50% of the voting power of the Common Stock of the
Company, Centocor will be able, among other things, to determine the outcome
of any corporate action requiring approval of holders of Common Stock
representing a majority of the voting power of the Common Stock, without the
consent of the other shareholders of the Company. In addition, through its
control of the Board of Directors and ownership of Class B Common Stock,
Centocor will be able to control certain decisions, including decisions with
respect to the Company's dividend policy, the Company's access to capital
(including borrowing from third party lenders and the issuance of additional
equity securities), mergers or other business combinations involving the
Company, the acquisition or disposition of assets by the Company and any
change in control of the Company.
 
  Centocor has advised the Company that its current intent is to continue to
hold all of its outstanding shares of Class B Common Stock. Further, pursuant
to the Underwriting Agreement, Centocor has agreed, subject to certain
exceptions, not to sell or otherwise dispose of any shares of Common Stock (or
any security convertible into or exchangeable or exercisable for Common Stock)
owned by it for a period of 180 days following the date of this Prospectus,
without the prior written consent of Morgan Stanley & Co. Incorporated.
However, after such 180 day period, there can be no assurance concerning the
period of time during which time Centocor will maintain its ownership of Class
B Common Stock. Beneficial ownership of at least 80% of the total voting power
and value of the Company's outstanding stock is generally required in order
for Centocor to continue to include the Company in its consolidated group for
federal income tax purposes. Additionally, ownership of at least 80% of the
total combined voting power of all classes of the Company's outstanding voting
stock and at least 80% of the total number of shares of each class of
nonvoting stock is required in order for Centocor to be able to effect a tax-
free spin-off of the Company under the Code. See "Description of Capital
Stock--Common Stock--Conversion Rights."
 
  The Company's relationship with Centocor will also be governed by the
following agreements which have been, or will be, entered into prior to
completion of the offering: Services Agreement, Revolving Credit Agreement,
Registration Rights Agreement, Tax Sharing Agreement and Indemnification
Agreement, the material terms of which are summarized below. Because the
Company is a wholly owned subsidiary of Centocor, none of these arrangements
will result from arm's length negotiations and, therefore, the prices charged
to the Company for services provided thereunder may be higher or lower than
prices that may be charged by third parties.
 
  The descriptions of agreements set forth below are intended to be summaries
and, while material terms of the agreements are set forth herein, the
descriptions are qualified in their entirety by reference to the relevant
agreements filed as exhibits to the Registration Statement of which this
Prospectus forms a part.
 
  Services Agreement. Prior to the completion of the offering, the Company and
Centocor will enter into a Services Agreement (the "Services Agreement")
relating to the provision of certain services by Centocor to the Company. The
services covered by the Services Agreement include: facilities, information
systems, telecommunication systems, payroll and benefits administration,
insurance, financial accounting, treasury services, library services,
regulatory services and human resources services. The Services Agreement
provides that the Company shall have the right, upon sixty days prior written
notice to Centocor, to reduce the level of, or terminate, any services
provided by Centocor under the Services Agreement. This reduction or
termination right will permit the Company to seek alternative, competitive
third party sources of the services presently provided by Centocor. The
Company anticipates that in 1998 it will pay approximately $8.0 million to
Centocor for such services.
 
                                      35
<PAGE>
 
  Revolving Credit Agreement. Centocor and the Company have entered into a
Revolving Credit Agreement pursuant to which Centocor has made available to
the Company a revolving credit facility in the maximum principal amount of
$5.0 million. Outstanding principal amounts under the credit facility accrue
interest at the annual rate equal to a stated, floating prime rate plus one
percent. The initial term of the Revolving Credit Agreement expires on August
23, 1998, and is subject to extension by the mutual agreement of Centocor and
the Company, provided, however, that Centocor must provide at least sixty days
prior written notice in the event that it does not intend to extend the term
of the Revolving Credit Agreement beyond such date. The Revolving Credit
Agreement includes affirmative and negative covenants of the Company which are
customary in revolving credit facilities. As of the date of this Prospectus,
the Company has not made any borrowings under the Revolving Credit Agreement.
 
  Registration Rights Agreement. The Company and Centocor intend to enter into
a Registration Rights Agreement to be effective upon the consummation of this
offering. The Registration Rights Agreement will provide that, upon the
request of Centocor, the Company will use its best efforts to effect the
registration under applicable federal and state securities laws of any of the
shares of Company Common Stock which Centocor intends to sell, and the Company
is required to take such other action necessary to permit the sale thereof
subject to certain limitations specified in the Registration Rights Agreement.
Centocor will also have the right, which it may exercise at any time and from
time to time, to include shares of Company Common Stock held by it in certain
other registrations of equity securities of the Company initiated by the
Company on its own behalf or on behalf of its other shareholders. The Company
will agree to pay all out-of-pocket costs and expenses in connection with each
such registration that Centocor requests or in which Centocor participates.
Subject to certain limitations specified in the Registration Rights Agreement,
such registration rights would be assignable by Centocor and its assigns.
 
  Tax Sharing Agreement. The Company is, and after the offering may continue
to be, included in Centocor's consolidated tax group and may be included in
the consolidated, combined or unitary federal income tax return, and any state
income tax return where Centocor files a consolidated, combined or unitary
state return. Centocor and the Company intend to enter into a Tax Sharing
Agreement that will be effective upon completion of the offering. Pursuant to
the Tax Sharing Agreement for the periods in which the Company is included in
Centocor's consolidated, combined or unitary tax group, Centocor and the
Company will make payments between them such that, with respect to any period,
the amount of taxes to paid by the Company will be determined as though the
Company were to file separate federal, state and local income tax returns
(including, except as provided below, any amounts determined to be due as a
result of a redetermination of the tax liability of Centocor arising from an
audit or otherwise). The Company shall not be liable however, to make payments
to Centocor on account of federal taxable income to the extent that Centocor
has remaining NOL's to offset its tax liability. Centocor will continue to
have all the rights of a common parent of a consolidated group, will be the
sole and exclusive agent for the Company in any and all matters relating to
the income tax liability of the Company in connection with consolidated or
combined federal and state returns, will have the sole and exclusive
responsibility for the preparation and filing of consolidated federal and
consolidated or combined state income tax returns and will have the power and
sole discretion to contest or compromise any asserted tax adjustment or
deficiency and to file, litigate or compromise any claim for refund on behalf
of the Company. Each member of a consolidated group for federal income tax
purposes is jointly and severally liable for the income tax liability of each
of the members of its consolidated group. Though valid as between the Company
and Centocor, the Tax Sharing Agreement is not binding on the Internal Revenue
Service and does not affect the several liability of Centocor and its
subsidiaries that are included in Centocor's consolidated group including the
Company, to the Internal Revenue Service for all federal income taxes due with
respect to Centocor's consolidated federal tax returns.
 
  Indemnification Agreement. The Company and Centocor have entered into an
Indemnification Agreement, pursuant to which Centocor will defend, indemnify
and hold harmless the Company, its affiliates and their respective directors,
officers, employees, agents and representatives, in connection with any
claims, losses, damages, suits, actions, costs and expenses, (including
reasonable attorneys' fees and expenses) which arise out of or result from the
activities of the business presently conducted by the Company, which occurred
on or before August 22, 1997, the date on which the business was transferred
from Centocor to the Company.

EMPLOYMENT AGREEMENTS
 
  Pursuant to a Letter Agreement dated July 21, 1997, and accepted July 22,
1997, Mr. Danehy is entitled to receive an annual base salary of $275,000,
subject to annual review. Mr. Danehy is also eligible to receive a cash bonus
in the first quarter of 1999 equal to no more than 20% of his base salary in
1998 with the maximum allowable bonus payable in the first quarter of each
subsequent year increasing by 10% annually for three years. The amount of the
bonus will vary from year to year based upon the overall performance of the
Company and individual objectives mutually agreed upon by Mr. Danehy and the
Company's Board of Directors. Mr. Danehy is entitled to be reimbursed for
temporary living and commuting expenses up to a maximum of $3,500 per month
for a period of no more than 30 months from his initial date of employment.
Under the Letter Agreement, Mr. Danehy will also be awarded stock options
under the Company's Employee Non-Qualified Stock Option Plan to purchase the
number of shares of Class A Common Stock equal to 5% of the outstanding
capital stock of the Company following this offering. In the event of
termination by the Company of his employment for any reason, except willful
failure to perform or dishonest conduct, the Company will be obligated to pay
Mr. Danehy's base salary on a bi-weekly basis for up to twelve months or until
such time that Mr. Danehy obtains similar employment, whichever time period is
shorter.
 
EMPLOYEE NON-QUALIFIED STOCK OPTION PLAN
 
  Under the Company's Employee Non-Qualified Stock Option Plan (the "Employee
Plan"), options to purchase shares of Common Stock of the Company may be
granted to employees of the Company as determined by the Compensation
Committee of the Company's Board of Directors. Under the Employee Plan, the
Company may grant options for up to an aggregate of     shares of Class A
Common Stock at an exercise price of not less than 100% of the fair market
value per share of the Company's Class A Common Stock on the date of grant.
Under the Employee Plan, the options vest with respect to 25% of the options
granted on the anniversary of the date of grant and the remaining options vest
at the rate of 2.1% per month provided the employee continues to be employed
by the Company. Options generally will expire ten years from the date of grant
if not exercised. A dissolution or liquidation of the Company or a merger or
consolidation in which the Company is not the surviving corporation will cause
each outstanding option to terminate, provided that each optionee, in such
event, will have the right immediately prior to said dissolution or
liquidation or merger or consolidation to exercise his option in whole or in
part without regard to any installment vesting provisions with respect to such
options. All options granted to executive officers will be granted in tandem
with limited stock appreciation rights ("LSARs"). LSARs may be exercised only
upon the occurrence of certain events constituting a change in control of
Centocor, only during the 30-day period following shareholder approval of any
such event (but may not in any event be exercised for six months after the
date of grant of the LSAR), and will be exercisable only if and to the extent
that the options to which they relate are exercisable. For each share for
which an LSAR is exercised, the optionee will receive an amount in cash equal
to the difference between (1) the exercise price per share of the option to
which the LSAR relates and (2) the fair market value per share of the Common
Stock issuable upon exercise of the option on the date the LSAR is exercised.
 
NON-EMPLOYEE DIRECTORS NON-QUALIFIED STOCK OPTION PLAN
 
  Under the Company's Directors' Non-Qualified Stock Option Plan (the
"Directors' Plan"), options to purchase shares of Common Stock of the Company
may be granted to directors who are not employees of the Company for a period
of at least one year prior to the date of grant. Under the Directors' Plan,
the Company may grant options for up to an aggregate of     shares of Class A
Common Stock at an exercise price of not less than 100% of the fair market
value per share of the Company's Class A Common Stock on the date of grant.
Under the Directors' Plan, the options vest with respect to 25% of the options
granted on the anniversary of the date of grant and the remaining options vest
at the rate of 2.1% per month provided the director continues to be a director
of the Company. Options generally will expire ten years from the date of grant
if not exercised. A dissolution or liquidation of the Company or a merger or
consolidation in which the Company is not the surviving corporation will cause
each outstanding option to terminate, provided that each optionee, in such
event, will have the right immediately prior to said dissolution or
liquidation or merger or consolidation to exercise his option in whole or in
part without regard to any installment vesting provisions with respect to such
options.

                             PRINCIPAL SHAREHOLDER
 
  Prior to this offering, the only shareholder of the Company is Centocor. As
of the date of this Prospectus, Centocor owns beneficially and of record
shares of Class B Common Stock, representing all of the shares of Common Stock
Outstanding prior to this offering. Upon completion of this offering, Centocor
will own beneficially and of record     shares, or approximately    % of the
outstanding Common Stock (   % if the Underwriters exercise their over-
allotment option in full). Centocor will therefore be able, acting alone, to
elect the entire Board of Directors of the Company and to control the vote on
matters submitted to a vote of the Company's shareholders. Except as described
above, the Company is not aware of any person or group that will beneficially
own more than 5% of the outstanding shares of Common Stock following this
offering.

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of     shares of Common
Stock, par value $.01 per share, of which (i)     shares are designated as
Class A Common Stock, (ii)     shares are designated as Class B Common Stock
and (iii)     shares are not designated by the Company's Articles of
Incorporation but are subject to designation as to class, series, rights,
limitations, and special rights, if any, by the Company's Board of Directors
prior to issuance. Of the     shares of Common Stock designated as Class A
Common Stock,    shares are being offered hereby. Of the     shares of Common
Stock designated as Class B Common Stock,    shares are outstanding and are
held by Centocor. A description of the material terms and provisions of the
Company's Articles of Incorporation, as amended and restated, affecting the
relative rights of the Class A Common Stock and the Class B Common Stock is
set forth below. This description is intended as a summary and is qualified in
its entirety by reference to the form of the Company's Amended and Restated
Articles of Incorporation filed with the Registration Statement of which this
Prospectus forms a part.
 
COMMON STOCK
 
  Voting rights. The holders of Class A Common Stock and Class B Common Stock
generally have identical rights except that holders of Class A Common Stock
are entitled to one vote per share while holders of Class B Common Stock are
entitled to 10 votes per share on all matters to be voted on by shareholders.
Holders of shares of Class A Common Stock and Class B Common Stock are not
entitled to cumulate their votes in the election of directors and have no
preemptive rights. Generally, all matters to be voted on by shareholders must
be approved by a majority (or, in the case of election of directors, by a
plurality) of the votes entitled to be cast by all shares of Class A Common
Stock and Class B Common Stock present in person or represented by proxy,
voting together as a single class.
 
  Dividends and Stock Splits. Holders of Class A Common Stock and Class B
Common Stock will share ratably in any dividend declared by the Board of
Directors. Dividends consisting of shares of Class A Common Stock and Class B
Common Stock may be paid only as follows: shares of Class A Common Stock may
be paid only to holders of shares of Class A Common Stock, and shares of Class
B Common Stock may be paid only to holders of Class B Common Stock. The
Company may not split, divide or combine the shares of either class of Common
Stock without at the same time splitting, dividing or combining the shares of
the other Class of Common Stock in the same proportion and manner.
 
  Conversion. Each share of Class B Common Stock is convertible while held by
Centocor or any of its subsidiaries at such holder's option into one share of
Class A Common Stock. Any shares of Class B Common Stock transferred to a
person other than Centocor or any of its subsidiaries shall automatically
convert to shares of Class A Common Stock, on a one-for-one basis, upon such
disposition, except for a disposition effected in connection with a transfer
of Class B Common Stock to shareholders of Centocor as a dividend intended to
be on a tax-free basis under the Code (a "Tax-Free Spin-Off"). In the event of
a Tax-Free Spin-Off, shares of Class B Common Stock shall automatically
convert into shares of Class A Common Stock on the fifth anniversary of the
Tax-Free Spin-Off unless prior to such Tax-Free Spin-Off Centocor delivers to
the Company an opinion of counsel (which counsel shall be reasonably
satisfactory to the Company) to the effect that such conversion would preclude
Centocor from obtaining a favorable ruling from the Internal Revenue Service
that the distribution would be a Tax-Free Spin-Off under the Code. If such an
opinion is received, approval of such conversion shall be submitted to a vote
of the holders of the Common Stock as soon as practicable after the fifth
anniversary of the Tax-Free Spin-Off unless Centocor delivers to the Company
an opinion of Centocor's counsel (which counsel shall be reasonably
satisfactory to the Company) prior to such anniversary that such vote would
adversely effect the status of the Tax-Free Spin-Off. Approval of such
conversion will require the affirmative vote of the holders of a majority of
the shares of both the Class A Common Stock and Class B Common Stock present
and voting, voting together as a single class with each share entitled to one
vote for such purpose.
 
  All shares of Class B Common Stock shall automatically convert into Class A
Common Stock if a Tax-Free Spin-Off has not occurred and the number of
outstanding shares of Class B Common Stock falls below a majority
 
                                      42
<PAGE>
 
of the aggregate number of outstanding shares of Common Stock. This will
prevent Centocor from decreasing its economic interest in the Company to less
than a majority while still retaining voting control. Such conversion will be
effected on a share-for-share basis. In addition, in order to give any holder
of the Class A Common Stock or Class B Common Stock the right to participate
in any offer for a significant amount of the shares of the other class that is
not similarly offered for the shares of such holder's class, following a Tax-
Free Spin-Off, shares of Common Stock of each class will be convertible, at
the option of the holder thereof, on a share-for-share basis, into shares of
the other class if any person (other than Centocor or any of its
subsidiaries), agreeing to act together for the purpose of acquiring, holding,
voting or disposing of shares of Common Stock, makes an offer, which the board
of directors deems to be a bona fide offer, to purchase 5% or more of other
class of Common Stock for cash and/or other securities or property without
making a similar offer for the shares of such class. The shares of Common
Stock of a class may only be so converted during the period in which the bona
fide offer is in effect. Any share of Common Stock so converted and not
acquired by the offeror prior to the termination of the offer will
automatically reconvert to a share of the class from which it was converted
upon such termination.
 
  Other Rights. In the event of any merger or consolidation of the Company
with or into another company, all holders of Common Stock, regardless of
class, will be entitled to receive the same kind and amount of shares of stock
and other securities and property (including cash). On liquidation,
dissolution or winding up of the Corporation, all holders of Common Stock,
regardless of class, are entitled to share ratably in any assets available for
distribution to holders of shares of Common Stock. No shares of either class
of Common Stock are subject to redemption or subscription rights.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is BankBoston, N.A.
c/o Boston Equiserve. Its address for such purposes is Shareholder Services,
P.O. Box 8040, Boston, Massachusetts 02266-8040, and its telephone number at
that address is (617) 575-3120.
 
CERTAIN ARTICLES OF INCORPORATION AND BYLAW PROVISIONS
 
  The Articles of Incorporation and Bylaws of the Company contain certain
provisions that may enhance the likelihood of continuity and stability in the
composition of the Board of Directors and may discourage a future unsolicited
takeover of the Company. These provisions could have the effect of
discouraging certain attempts to acquire the Company or remove incumbent
management, including incumbent members of the Board of Directors, even if
some or a majority of the Company's shareholders deem such an attempt to be in
their best interests.
 
  Upon completion of this offering, the Company's Board of Directors will have
the authority to issue up to     shares of capital stock and to determine the
price, rights, preferences, privileges and restrictions, including voting
rights of such shares, without any further vote or action by the Company's
shareholders. Such charter provisions could have the effect of delaying or
preventing a change of control of the Company. The rights of the holders of
Common Stock may be subject to, and may be adversely affected by, the rights
of the holders of any capital stock that may be issued in the future. The
issuance of any such shares of capital 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 current plans to issue any shares of such capital stock.
 
  The Company's Articles of Incorporation, as amended and restated, or Bylaws,
as applicable, among other things (i) provide that the number of directors
will determined from time to time by the Board of Directors through a
resolution adopted by a majority of the Board of Directors, (ii) permit
vacancies on the Board of Directors that may occur between annual meetings and
newly created seats to be filled only by the Board of Directors and not by the
shareholders, (iii) do not permit the shareholders to call special meetings of
shareholders, (iv) provide that the Board of Directors, without action by the
shareholders, may issue and fix the rights and preferences of shares of new
classes or series of the Company's capital stock, and (v) permit
 
                                      43
<PAGE>
 
shareholder action, without a meeting, upon the written consent of
shareholders who would have been entitled to cast the minimum number of votes
that would be necessary to authorize the action at a meeting at which all
shareholders entitled to vote on such action were present and voting without
prior notice to the remaining shareholders. These provisions may have the
effect of delaying, deferring or preventing a change of control of the Company
without further action by the shareholders, may discourage bids for the Common
Stock at a premium over the market price of the Common Stock and may adversely
affect the market price of, and the voting or other rights of the holders of,
the Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  The     shares of Class A Common Stock sold in the offering (    shares if
the Underwriters exercise their over-allotment option in full) will be freely
tradable without restriction under the Securities Act, except for any such
shares which may be acquired by an affiliate of the Company (an "Affiliate"),
as that term is defined in Rule 144 promulgated under the Securities Act
("Rule 144"). Persons who may be deemed to be Affiliates generally include
individuals or entities that control, are controlled by, or are under common
control with, the Company and may include directors and certain officers of
the Company as well as significant shareholders of the Company, if any.
Persons who are Affiliates will be permitted to sell the shares of Class A
Common Stock that are issued in this offering only pursuant to an effective
registration statement under the Act or an exemption from the registration
requirements of the Securities Act, including exemptions provided by Rule 144.
 
  The shares of Class A Common Stock held by Centocor are deemed "restricted
securities" as defined in Rule 144, and may not be sold other than through
registration under the Securities Act or pursuant to an exemption from the
regulations thereunder, including exceptions provided by Rule 144. The
Company, Centocor and certain other persons have agreed not to offer or sell
any shares of Common Stock, subject to certain exceptions, for a period of 180
days after the date of this Prospectus, without the prior written consent of
Morgan Stanley & Co. Incorporated. See "Underwriters."

  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Class A Common
Stock offered hereby are subject to the approval of certain legal matters by
their counsel and to certain other conditions. The Underwriters are obligated
to take and pay for all of the shares of Class A Common Stock offered hereby
(other than those covered by the Underwriters' over-allotment option described
below) if any such shares are taken.
 
  The Underwriters initially propose to offer part of the shares of Class A
Common Stock directly to the public at the public offering price set forth on
the cover page hereof and part to certain dealers at a price which represents
a concession not in excess of $   per share under the public offering price.
The Underwriters may allow, and such dealers may reallow, a concession not in
excess of $    per share to other Underwriters or to certain dealers. After
the initial offering of the shares of Class A Common Stock, the offering price
and other selling terms may from time to time be varied by the Underwriters.
 
  Application has been made to list the Class A Common Stock for quotation on
the Nasdaq National Market System under the symbol "CNDX."
 
  The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to      additional
shares of Class A Common Stock at the public offering price set forth on the
cover page hereof, less underwriting discounts and commissions. The
Underwriters may exercise such option to purchase solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
shares of Class A Common Stock offered hereby. To the extent such option is
exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number set forth next to such Underwriter's name in the
preceding table bears to the total number of shares of Class A Common Stock
offered by the Underwriters in the offering.
 
  Centocor, the Company and the Company's executive officers, directors and
shareholders have agreed that, without the prior written consent of Morgan
Stanley & Co. Incorporated, they will not (i) offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase or otherwise transfer
or dispose of, directly or indirectly, any shares of Class A Common Stock or
any securities convertible into or exercisable or exchangeable for Class A
Common Stock or (ii) enter into any swap or other arrangement that transfers
to another, in whole or in part, any of the economic consequences of ownership
of Class A Common Stock, whether any such transaction described in clause (i)
or (ii) of above is to be settled by delivery of Class A Common Stock or other
securities, in cash or otherwise, for a
 
                                      45
<PAGE>
 
period of 180 days after the date of this Prospectus, other than the shares of
Class A Common Stock offered hereby.
 
  At the request of the Company, the Underwriters have reserved for sale at
the initial offering price up to     shares of Class A Common Stock offered
hereby for officers, directors, employees and certain other persons associated
with the Company. The number of shares available for sale to the general
public will be reduced to the extent such persons purchase such reserved
shares. Any reserved shares not so purchased will be offered by the
Underwriters to the general public on the same basis as the other shares
offered hereby.
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Class A Common Stock offered by them.
 
  The Company, Centocor and the Underwriters have agreed to indemnify each
other against certain liabilities, including liabilities under the Securities
Act.
 
  In order to facilitate the offering of the Class A Common Stock, the
Underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the Class A Common Stock. Specifically, the Underwriters
may overallot in connection with the offering, creating a short position in
the Class A Common Stock for their own account. In addition, to cover
overallotments or to stabilize the price of the Common Stock, the Underwriters
may bid for, and purchase, shares of Class A Common Stock in the open market.
Finally, the underwriting syndicate may reclaim selling concessions allowed to
an underwriter or a dealer for distributing the Class A Common Stock in the
offering, if the syndicate repurchases previously distributed Class A Common
Stock in transactions to cover syndicate short positions, in stabilization
transactions or otherwise. Any of these activities may stabilize or maintain
the market price of the Class A Common Stock above independent market levels.
The Underwriters are not required to engage in these activities, and may end
any of these activities at any time.
 
  From time to time, each of Morgan Stanley & Co. Incorporated and Credit
Suisse First Boston Corporation have provided certain financial advisory
services to Centocor.
 
PRICE OF THE OFFERING
 
  Prior to this offering, there has been no public market for the Class A
Common Stock. The initial public offering price for the Class A Common Stock
was determined by negotiations between the Company and the Underwriters. Among
the factors considered in determining the initial public offering price were
the revenues, earnings and certain other pro forma financial and operating
information of the Company in recent periods, the future prospects of the
Company and its industry in general, and certain ratios and market prices of
securities and certain financial and operating information of companies
engaged in activities similar to those of the Company.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholder
Centocor Diagnostics, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Centocor
Diagnostics, Inc. and subsidiaries as of December 31, 1995 and 1996, and the
related consolidated statements of operations, cash flows and shareholder's
equity for each of the years in the three-year period ended December 31, 1996.
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 Centocor
Diagnostics, Inc., and subsidiaries as of December 31, 1995 and 1996 and the
results of their operations and cash flows for each of the years in the three-
year period ended December 31, 1996, in conformity with generally accepted
accounting principles.

                  CENTOCOR DIAGNOSTICS, INC. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--ORGANIZATION
 
  Centocor Diagnostics develops, manufactures and sells diagnostic human
health care products based primarily upon monoclonal antibody technologies.
The Company's products and product candidates focus primarily on oncology and
cardiovascular diseases. The Company is a leading provider of IVD tests,
components and reagents to monitor the efficacy of cancer therapies, primarily
in patients with breast, ovarian or pancreatic cancer.
 
  Prior to the Company's formation as a Pennsylvania corporation on August 22,
1997, it operated as a division of Centocor, Inc. ("Centocor"). On August 22,
1997, the assets and liabilities of the division were contributed to the
Company, which is a wholly-owned subsidiary of Centocor in exchange for all
common shares, par value $.01 per share. The transaction was accounted for as
a reorganization of entities under common control and, accordingly, the assets
and liabilities were recorded at their historical book value.
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Presentation
 
  The accompanying financial statements include the accounts of Centocor
Diagnostics as a division of Centocor through August 22, 1997 and as Centocor
Diagnostics, Inc. and subsidiaries thereafter. All significant intercompany
balances and transactions have been eliminated in consolidation.
 
  Significant management assumptions were made in allocating costs from
Centocor in order to present the balance sheets and statements of operations.
Management of the Company believes that such costs have been reasonably
allocated.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
 Inventory
 
  Inventory is stated at the lower of cost or market value using the first-in,
first-out method. Inventories have various expiration dates. Valuation
adjustments are provided for inventories which are likely to expire prior to
sales or likely to otherwise not be available for sale.
 
 Equipment and Furniture
 
  Equipment and furniture and fixtures are stated at cost. Depreciation is
provided using the straight-line method over the estimated useful lives of the
assets, which range from 3 to 5 years.
 
 Intangible and Other Assets
 
  Intangible and other assets are stated at cost, net of accumulated
amortization. Amortization is provided using either the straight-line method
or more applicable methods over the estimated useful lives, generally 3 to 20
years. Licensing agreements and other assets are reviewed for impairment
whenever events or circumstances provide evidence that suggest that the
carrying amount of the asset may not be recoverable. Impairment is evaluated
by using undiscounted identified or expected cash flows.
 
 Revenue Recognition
 
  Sales revenues for completed kits and components are recognized when goods
are shipped. For certain bulk reagents, sale revenues are recognized upon
shipment of product to the final end user.

<PAGE>
 
                  CENTOCOR DIAGNOSTICS, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Revenues associated with research and development or commercialization
agreements are recognized when they are earned in accordance with the
applicable performance requirements and other contractual terms. Payments
received which are related to the performance of future services are deferred
and recognized as revenue over the ensuing period in which the service is
rendered.
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standard No. 109, Accounting for Income Taxes ("SFAS
109"). The provision for Federal and State income taxes is calculated as if
the Company were a stand-alone corporation filing separate returns. Deferred
income taxes are recognized based upon future income tax effects (using
enacted tax laws and rates) of differences in the carrying amounts of assets
and liabilities for financial reporting and tax purposes. A valuation
allowance is recognized if it is more likely than not that some or all of a
deferred tax asset will not be realized.
 
 Cash and Cash Equivalents
 
  Cash and cash equivalents consist of amounts held as bank deposits and
marketable securities with a maturity of three months or less.
 
 Fair Value of Financial Instruments
 
  Cash and cash equivalents, accounts and contracts receivable, prepaid
expenses, other current assets, accounts payable, and accrued expenses
reported in the consolidated balance sheets equal or approximate fair value
due to their short maturities.
 
NOTE 3--COMMITMENTS AND CONTINGENCIES
 
 Liquidity and Capital Resources
 
  The Company has incurred significant operating expenses developing,
manufacturing and marketing diagnostic products.
 
  The Company's future financial condition is dependent upon the Company's
rate of net cash outflows and levels of diagnostic product sales. For the year
ended December 31, 1996, sales of the Company's products generated sufficient
revenue to result in positive cash flow for the year. The level of future
sales of diagnostic products and services will be dependent upon several
factors, including, but not limited to, the development of instrumentation
technologies by a third party, the timing and extent of future regulatory
approvals of the Company's products, approval and commercialization of
competitive products and the degree of acceptance of the Company's products in
the marketplace. There can be no assurance that the U.S. Food and Drug
Administration (FDA) or other regulatory approvals expanding the authorized
use of, or permitting the commercial sale of any of the Company's product
candidates under development will be obtained. Failure to obtain additional
timely FDA or other regulatory approvals for the use of product candidates
will have a material adverse effect on the Company.
 
 Royalties
 
  The Company has entered into agreements to support research at certain
research institutions. These agreements, which grant the Company licenses
and/or options to license certain technology resulting from the research,
generally require the Company to pay royalties to such institutions on the
sales of any products that utilize the licensed technology. Further, the
Company has licenses under certain patents, patent applications and technology
and pays the licensors or their licensees royalties under such agreements.
 
  All royalties are reflected in cost of sales as incurred. Royalty costs
represent a significant percentage of cost of sales.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Product Liability
 
  The testing and marketing of medical products entails an inherent risk of
product liability. The Company maintains limited product liability insurance
coverage through Centocor. Centocor Diagnostics' business may be materially
adversely affected by a successful product liability claim in excess of any
insurance coverage. There can be no assurance that product liability insurance
coverage will continue to be available to Centocor Diagnostics in the future
on reasonable terms or at all.

  Inventory, net of valuation adjustments, consists of the following (in

  Inventories have various expiration dates. The Company continually evaluates
the extent of inventory reserves considered necessary based upon the future
regulatory and commercial status of such products. There can be no assurance
that additional valuation adjustments for inventories will not be required in
the future.
 
NOTE 5--INTANGIBLE AND OTHER ASSETS
 
  Intangible and other assets consist of the following, net of accumulated

NOTE 6--INVESTMENTS
 
  In 1996, in compensation for its prior research and commercialization
efforts and the exchange of a commercialization license the Company received
an 8.8% ownership (7.8% on a fully diluted basis) interest in Chromavision.
The Company's historical basis in this investment is $770,000 and it is valued
at $9,988,000 as of September 30, 1997 (unaudited) and is classified as
available for sale with unrealized gains and losses recorded as a component of
shareholder's equity. Under an agreement with Chromavision's underwriters, the
Company has agreed that it will not sell or otherwise dispose of any
Chromavision stock until after a period of 180 days that commenced on August
5, 1997 (the effective date of the Chromavision offering), without the prior
consent of the Chromavision underwriters.

NOTE 10--INCOME TAXES
 
  The Company is a member of a consolidated group having significant Federal
net operating loss carryforwards. To the extent the Company generates taxable
book earnings on a separate company basis, if any, it will record a tax
provision in accordance with SFAS 109.
 
  Under a tax sharing agreement to be entered into between Centocor and the
Company, the Company will make no payments to Centocor for its use, if any, of
the consolidated group's U.S. Federal income tax net operating loss and tax
credit carryforwards. (See Note 11--Related Party Transactions) The extent to
which the Company's future Federal income tax liability will continue to be
sheltered by Centocor's net operating loss carryforward is dependent upon the
rate at which Centocor's consolidated group generates future taxable earnings,
if any. To the extent that Centocor's net operating loss and tax credit
carryforwards are no longer available to shelter its consolidated group's
future taxable income, if any, the Company will then be required to make
payments to Centocor for its portion of the consolidated group's tax
liability. The provisions for income taxes in the accompanying financial
statements were calculated as if the expected tax sharing agreement had been
in effect for all periods presented. In the event the Company ceases to be a
member of the Centocor consolidated tax group, the Company will be subject to
payment of income taxes as a stand-alone corporation.
 
  Had the Company been subject to SFAS 109, as a separate company for the
periods presented below, the Company's components of the provision for income
taxes, its statutory tax rate reconciliation and its components of deferred

 Personnel Related Benefits
 
  The Company and Centocor have an arrangement in which the Company is charged
for stock compensation and employee health and life insurance benefits
expenses related to the employees of the Company. The employees of the Company
participate in Centocor's Qualified Savings and Retirement Plan (the "Plan").
Employee benefits are based solely on the employees' discretionary
contributions and Centocor's discretionary matching contribution. Centocor
generally makes its discretionary matching contribution in shares of its
common stock. Centocor Diagnostics share of the discretionary contribution
totaled $153,000, $215,000, and $216,000 in 1994, 1995, and 1996 respectively,
and $116,000 and $153,000 for the nine months ended September 30, 1996 and
1997, respectively. Employee contributions to the Plan may be invested in
various instruments, including Centocor's common stock, at the discretion of
the employee.
 
  Centocor Diagnostics' Qualified Savings and Retirement Plan was established
on August 22, 1997, the provisions of which are substantially the same as the
Plan.
 
 Stock Option and Restricted Stock Award Plans
 
  The employees of Centocor Diagnostics participate in Centocor's stock option
plans pursuant to which options to purchase a total of approximately 9,050,000
Shares of Centocor Common Stock have been authorized for grant to Centocor's
employees and to its non-employee directors. Under the terms of these plans,
the option exercise price may not be less than the fair market value of the
underlying stock at the time the option is granted. The options granted under
these plans generally expire upon the earlier of the termination of the
optionee's employment or service or ten years from the date of the grant.
 
  Centocor has adopted Statement of Financial Accounting Standard No. 123
"Accounting for Stock-Based Compensation" ("SFAS 123") which was issued in
October 1995 and is effective for transactions entered into in fiscal years
beginning after December 15, 1995. In accordance with the provisions of SFAS
123, which allow Centocor to apply Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees", and related interpretations in
accounting for its stock option plans and accordingly, Centocor does not
recognize compensation cost for options granted. As such, the accompanying
financial statements of Centocor Diagnostics reflect no allocation of
compensation costs for its employees.
 
  The Company will adopt a stock option plan (the "Stock Option Plan") under
which directors, officers and employees may be granted options to purchase
shares of Class A Common Stock. Options are granted at fair market value at
the date of grant. Options are exercisable under specified conditions for up
to 10 years from the date of grant. Under provisions of the Stock Option Plan,
participants may deliver to the Company stock in payment of the option price
and receive credit for the fair market value of the shares of Common Stock
delivered on the date of delivery.
 
 Tax-Sharing Agreement
 
  Pursuant to a tax sharing agreement expected to be entered into between
Centocor and the Company, the Company will make no payments to Centocor for
its use, if any, of the consolidated group's U.S. Federal income tax net
operating loss and tax credit carryforwards. The Company will treat any such
usage as a contribution of capital from Centocor. In future years, to the
extent that Centocor's net operating loss and tax credit carryforwards are no
longer available to shelter the consolidated group's taxable income, if any,
the Company will then be required to make payments to Centocor for its portion
of the consolidated group's tax liability.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The form of Underwriting Agreement filed as Exhibit 1.1 hereto contains
certain provisions relating to indemnification. The Pennsylvania Business
Corporation Law (the "BCL") authorizes the registrant to grant indemnities to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act.
 
Article 24 of the Company's Bylaws provides as follows:
 
         "INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS
 
  SECTION 24.1 The Corporation shall indemnify any director or officer, and
may indemnify any other employee or agent, who was or is a party to, or is
threatened to be made a party to, or who is called as a witness in connection
with, any threatened, pending, or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, including an action
by or in the right of the Corporation, by reason of the fact that he 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 domestic or foreign corporation, for profit or not-for-
profit, partnership, joint venture, trust or other enterprise, against
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such
action, suit or proceeding unless the act or failure to act giving rise to the
claim for indemnification is determined by a court to have constituted willful
misconduct or recklessness.
 
  SECTION 24.2 The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article 24 shall not be deemed exclusive of any
other rights to which those seeking indemnification or advancement of expenses
may be entitled under any Bylaw, agreement, contract, vote of shareholders or
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office. It is the policy of the
Corporation that indemnification of, and advancement of expenses to, directors
and officers of the Corporation shall be made to the fullest extent permitted
by law. To this end, the provisions of this Article 24 shall be deemed to have
been amended for the benefit of directors and officers of the Corporation
effective immediately upon any modification of the BCL or any modification or
adoption of any other law that
 
                                     II-1
<PAGE>
 
expands or enlarges the power or obligation of corporations organized under
the BCL to indemnify, or advance expenses to, directors and officers of
corporations.
 
  SECTION 24.3 The Corporation shall pay expenses incurred by an officer or
director, and may pay expenses incurred by any other employee or agent, in
defending an action, or proceeding referred to in this Article 24 in advance
of the final disposition of such action or proceeding upon receipt of an
undertaking by or on behalf of such person to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Corporation.
 
  SECTION 24.4 The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article 24 shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such person.
 
  SECTION 24.5 The Corporation shall have the authority to create a fund of
any nature, which may, but need not, be under the control of a trustee, or
otherwise secure or insure in any manner, its indemnification obligations,
whether arising under these Bylaws or otherwise. This authority shall include,
without limitation, the authority to: (a) deposit funds in trust or in escrow;
(b) establish any form of self-insurance; (c) secure its indemnity obligation
by grant of a security interest, mortgage or other lien on the assets of the
Corporation; or (d) establish a letter of credit, guaranty or surety
arrangement for the benefit of such persons in connection with the anticipated
indemnification or advancement of expenses contemplated by this Article 24.
The provisions of this Article 24 shall not be deemed to preclude the
indemnification of, or advancement of expenses to, any person who is not
specified in Section 24.1 of this Article 24 but whom the Corporation has the
power or obligation to indemnify, or to advance expenses for, under the
provisions of the BCL or otherwise. The authority granted by this Section 24.5
shall be exercised by the Board of Directors of the Corporation.
 
  SECTION 24.6 The Corporation shall have the authority to enter into a
separate indemnification agreement with any officer, director, employee or
agent of the Corporation or any subsidiary providing for such indemnification
of such person as the Board of Directors shall determine up to the fullest
extent permitted by law.
 
  SECTION 24.7 As soon as practicable after receipt by any person specified in
Section 24.1 of this Article 24 of notice of the commencement of any action,
suit or proceeding specified in Section 24.1 of this Article 24, such person
shall, if a claim with respect thereto may be made against the Corporation
under Article 24 of these Bylaws, notify the Corporation in writing of the
commencement or threat thereof; however, the omission so to notify the
Corporation shall not relieve the Corporation from any liability under Article
24 of these Bylaws unless the Corporation shall have been prejudiced thereby
or from any other liability which it may have to such person other than under
Article 24 of these Bylaws. With respect to any such action as to which such
person notifies the Corporation of the commencement or threat thereof, the
Corporation may participate therein at its own expense and, except as
otherwise provided herein, to the extent that it desires, the Corporation,
jointly with any other indemnifying party similarly notified, shall be
entitled to assume the defense thereof, with counsel selected by the
Corporation to the reasonable satisfaction of such person. After notice from
the Corporation to such person of its election to assume the defense thereof,
the Corporation shall not be liable to such person under Article 24 of these
Bylaws for any legal or other expenses subsequently incurred by such person in
connection with the defense thereof other than as otherwise provided herein.
Such person shall have the right to employ his own counsel in such action, but
the fees and expenses of such counsel incurred after notice from the
Corporation of its assumption of the defense thereof shall be at the expense
of such person unless: (a) the employment of counsel by such person shall have
been authorized by the Corporation; (b) such person shall have reasonably
concluded that there may be a conflict of interest between the Corporation and
such person in the conduct of the defense of such proceeding; or (c) the
Corporation shall not in fact have employed counsel to assume the defense of
such action. The Corporation shall not be entitled to assume the defense of
any proceeding brought by or on behalf of the Corporation or as to which such
person shall have reasonably concluded that there may be a conflict of
interest. If indemnification under Article 24 of these Bylaws or advancement
of expenses are not paid or made
 
                                     II-2
<PAGE>
 
by the Corporation, or on its behalf, within 90 days after a written claim for
indemnification or a request for an advancement of expenses has been received
by the Corporation, such person may, at any time thereafter, bring suit
against the Corporation to recover the unpaid amount of the claim or the
advancement of expenses. The right to indemnification and advancements of
expenses provided hereunder shall be enforceable by such person in any court
of competent jurisdiction. The burden of proving that indemnification is not
appropriate shall be on the Corporation. Expenses reasonably incurred by such
person in connection with successfully establishing the right to
indemnification or advancement of expenses, in whole or in part, shall also be
indemnified by the Corporation.
 
  SECTION 24.8 The Corporation shall have the power to 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 domestic or
foreign corporation for profit or not-for-profit, partnership, joint venture,
trust or other enterprise against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such,
whether or not the Corporation would have the power to indemnify him against
such liability under the provisions of this Article 24.
 
  SECTION 24.9 Notwithstanding any other provisions of these Bylaws, the
approval of shareholders shall be required to amend, repeal or adopt any
provision as part of these Bylaws that is inconsistent with the purpose or
intent of this Article 24, and, if such action shall be taken, it shall become
effective only on a prospective basis from and after the date of such
shareholder approval."
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
  On August 22, 1997, in reliance upon the exemption contained in Section 4(2)
of the Securities Act, the Company issued 12,000,000 shares of Common Stock to
Centocor in exchange for all of the capital stock of the subsidiaries which
own all of the assets, subject to the liabilities, which comprised the
oncology and cardiovascular diagnostics business of Centocor. Effective on
   , 1997, pursuant to an amendment and restatement of the Company's Articles
of Incorporation, the      shares of the Company's Common Stock held by
Centocor were reclassified into      shares of Class B Common Stock of the
Company.

ITEM 17. UNDERTAKINGS
 
  The undersigned registrant hereby undertakes to provide to the Underwriters
at the closing of the Offering 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 for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than
the payment by the 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, 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 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 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 497(h) under the
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 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.

name are held for the account of a specified person or persons. Such resolution
may set forth: (a) the classification of shareholder who may certify; (b) the
purpose or purposes for which the certification may be made; (c) the form of

appointment of an officer or agent shall not of itself create contract rights.
If the office of any officer becomes vacant for any reason, the vacancy may be
filled by the Board of Directors.

or proceeding, whether civil, criminal, administrative or investigative,
including an action by or in the right of the Corporation, by reason of the fact
that he 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 domestic or foreign corporation, for profit or not-
for-profit, partnership, joint venture, trust or other enterprise, against
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such
action, suit or proceeding unless the act or failure to act giving rise to the
claim for indemnification is determined by a court to have constituted willful
misconduct or recklessness.

    Section 24.2    The indemnification and advancement of expenses provided by,
    ------------                                                                
or granted pursuant to, this Article 24 shall not be deemed exclusive of any
other rights to which those seeking indemnification or advancement of expenses
may be entitled under any Bylaw, agreement, contract, vote of shareholders or
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office.  It is the policy of the
Corporation that indemnification of, and advancement of expenses to, directors
and officers of the Corporation shall be made to the fullest extent permitted by
law.  To this end, the provisions of this Article 24 shall be deemed to have
been amended for the benefit of directors and officers of the Corporation
effective immediately upon any modification of the BCL or any modification or
adoption of any other law that expands or enlarges the power or obligation of
corporations organized under the BCL to indemnify, or advance expenses to,
directors and officers of corporations.

    Section 24.3    The Corporation shall pay expenses incurred by an officer or
    ------------                                                                
director, and may pay expenses incurred by any other employee or agent, in
defending an action, or proceeding referred to in this Article 24 in advance of
the final disposition of such action or proceeding upon receipt of an
undertaking by or on behalf of such person to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Corporation.

    Section 24.4    The indemnification and advancement of expenses provided by,

authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to

the benefit of the heirs, executors and administrators of such person.

    Section 24.5    The Corporation shall have the authority to create a fund of
    ------------                                                                
any nature, which may, but need not, be under the control of a trustee, or
otherwise secure or insure in any manner, its indemnification obligations,
whether arising under these Bylaws or otherwise.  This authority shall include,
without limitation, the authority to: (a) deposit funds in trust or in escrow;
(b) establish any form of self-insurance; (c) secure its indemnity obligation by
grant of a security interest, mortgage or other lien on the assets of the
Corporation; or (d) establish a letter of credit, guaranty or surety arrangement
for the benefit of such persons in connection with the anticipated
indemnification or advancement of expenses contemplated by this Article 24.  The
provisions of this Article 24 shall not be deemed to preclude the
indemnification of, or advancement of expenses to, any person who is not
specified in Section 24.1 of this Article 24 but whom the Corporation has the
power or obligation to indemnify, or to advance expenses for, under the
provisions of the BCL or otherwise.  The authority granted by this Section 24.5
shall be exercised by the Board of Directors of the Corporation.

    Section 24.6    The Corporation shall have the authority to enter into a
    ------------                                                            
separate indemnification agreement with any officer, director, employee or agent
of the Corporation or any subsidiary providing for such indemnification of such
person as the Board of Directors shall determine up to the fullest extent
permitted by law.

    Section 24.7    As soon as practicable after receipt by any person specified
    ------------                                                                
in Section 24.1 of this Article 24 of notice of the commencement of any action,
suit or proceeding specified in Section 24.1 of this Article 24, such person
shall, if a claim with respect thereto may be made against the Corporation under
Article 24 of these Bylaws, notify the Corporation in writing of the
commencement or threat thereof; however, the omission so to notify the
Corporation shall not relieve the Corporation from any liability under Article
24 of these Bylaws unless the Corporation shall have been prejudiced thereby or
from any other liability which it may have to such person other than under
Article 24 of these Bylaws.  With respect to any such action as to which such
person notifies the Corporation of the commencement or threat thereof, the
Corporation may participate therein at its own expense and, except as otherwise
provided herein, to the extent that it desires, the Corporation, 

                                      -17-
<PAGE>
 
jointly with any other indemnifying party similarly notified, shall be entitled
to assume the defense thereof, with counsel selected by the Corporation to the
reasonable satisfaction of such person. After notice from the Corporation to
such person of its election to assume the defense thereof, the Corporation shall
not be liable to such person under Article 24 of these Bylaws for any legal or
other expenses subsequently incurred by such person in connection with the
defense thereof other than as otherwise provided herein. Such person shall have
the right to employ his own counsel in such action, but the fees and expenses of
such counsel incurred after notice from the Corporation of its assumption of the
defense thereof shall be at the expense of such person unless: (a) the
employment of counsel by such person shall have been authorized by the
Corporation; (b) such person shall have reasonably concluded that there may be a
conflict of interest between the Corporation and such person in the conduct of
the defense of such proceeding; or (c) the Corporation shall not in fact have
employed counsel to assume the defense of such action. The Corporation shall not
be entitled to assume the defense of any proceeding brought by or on behalf of
the Corporation or as to which such person shall have reasonably concluded that
there may be a conflict of interest. If indemnification under Article 24 of
these Bylaws or advancement of expenses are not paid or made by the Corporation,
or on its behalf, within 90 days after a written claim for indemnification or a
request for an advancement of expenses has been received by the Corporation,
such person may, at any time thereafter, bring suit against the Corporation to
recover the unpaid amount of the claim or the advancement of expenses. The right
to indemnification and advancements of expenses provided hereunder shall be
enforceable by such person in any court of competent jurisdiction. The burden of
proving that indemnification is not appropriate shall be on the Corporation.
Expenses reasonably incurred by such person in connection with successfully
establishing the right to indemnification or advancement of expenses, in whole
or in part, shall also be indemnified by the Corporation.

    Section 24.8    The Corporation shall have the power to purchase and

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 domestic or
foreign corporation for profit or not-for-profit, partnership, joint venture,

                                      -18-

trust or other enterprise against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such,
whether or not the Corporation would have the power to indemnify him against
such liability under the provisions of this Article 24.

    Section 24.9    Notwithstanding any other provisions of these Bylaws, the
    ------------                                                             
approval of shareholders shall be required to amend, repeal or adopt any
provision as part of these Bylaws that is inconsistent with the purpose or
intent of this Article 24, and, if any such action shall be taken, it shall
become effective only on a prospective basis from and after the date of such
shareholder approval.

certificates. The share certificates of the Corporation shall be numbered and
registered in a share register as they are issued; shall state that the
Corporation is incorporated under the laws of the Commonwealth of Pennsylvania;
shall bear the name of the registered holder, the number and class of shares and
the designation of the series, if any, represented thereby, the par value, if
any, of each share or a statement that the shares are without par value, as the
case may be; shall be signed by the President or a Vice President, and the
Secretary or the Treasurer or any other person properly authorized by the Board
of Directors; and shall bear the corporate seal, which seal may be a facsimile
engraved or printed. Where the certificate is signed by a transfer agent or a
registrar, the signature of any corporate officer on such certificate may be a
facsimile engraved or printed.  In case any officer who has signed, or whose
facsimile signature has been placed upon, any share certificate shall have
ceased to be such officer because of death, resignation or otherwise before the
certificate is issued, such share certificate may be issued by the Corporation
with the same effect as if the officer had not ceased to be such at the date of
its issue.

provided pursuant to Section 6.2 hereof, a transferee of shares of the
Corporation shall not become a record holder of such shares entitled to the
rights and benefits associated therewith unless and until the share transfer has
been recorded on the share transfer books of the Corporation.  No transfer shall
be made if it would be inconsistent with the provisions of Article 8 of the
Uniform Commercial Code as then in effect in the Commonwealth of Pennsylvania.

satisfactory to the Board of Directors setting forth the facts in connection
therewith, provided that prior to the receipt of such request the Corporation
shall not have either registered a transfer of such certificate or received
notice that such certificate has been acquired by a bona fide purchaser. When
authorizing such an issuance of a new certificate the Board of Directors may, in
its discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate, or his heirs or legal
representatives, as the case may be, to advertise the same in such manner as it
shall require and/or give the Corporation a bond in such form and sum and with
surety or sureties, with fixed or open penalty, as shall be satisfactory to the

transacted at, nor the purpose of, a meeting need be specified in the waiver of
notice. In the case of a special meeting of shareholders, the waiver of notice

of any person, whether in person or by proxy, at any meeting shall constitute a
waiver of notice of such meeting, except where a person attends a meeting

     4.1  --   (a)  As compensation to DANA-FARBER for the exclusive licenses
granted herein, CENTOCOR EUROPE agrees to pay to DANA-FARBER royalties on Net
Sales on a country-by-country basis, in an amount equal to   [**]   percent [**]
of Net Sales for the term of such exclusive license subject to such adjustments
as provided herein.

               (b) If CENTOCOR EUROPE has to pay royalties to a third party or
parties due to know-how or proprietary information or a valid patent that
CENTOCOR EUROPE reasonably believes the Licensed Products or Technology
infringe, royalties due under Section 4.1 hereof will be reduced by the
royalties payable to said third party or parties, but in no event shall the
royalties due under Section 4.1 hereof be reduced by more than [**] percent [**]
in any payment period. The return of any payments to CENTOCOR EUROPE because any
such patent is invalidated or such know-how is determined to be in the public
domain


                                       6
<PAGE>
 
shall be paid to DANA-FARBER to the extent necessary to restore the reduced
royalty payment.

               (c) In the event that two or more antibodies, the rights to
which have been licensed from different institutions, are employed by CENTOCOR
EUROPE in a Licensed Product, royalties payable to DANA-FARBER on sales of such
Licensed Products shall be [**] percent [**] of Net Sales multiplied by a
fraction, the denominator of which is the number of antibodies incorporated in
said product and the numerator of which is 1 (one). but in no event shall
royalties payable to DANA-FARBER be less than [**] and in such case, 4.1(b)
shall not be applicable

     4.2  --   Royalty on Net Sales shall be paid quarterly in arrears, on or

United States other than those denominated in U.S. dollars will be payable to
DANA-FARBER in United States Dollar equivalents at the official rate of exchange
of the currency of the country from which the royalties are payable (determined
by the same method used by CENTOCOR for reporting foreign sales to its
shareholders and governmental agencies).  If the transfer of or the conversion
into the United States Dollar equivalent of any such remittance in any such
instance is not lawful or possible, CENTOCOR EUROPE shall cause the payment of
such part of the royalties as is necessary to be made by the deposit thereof, in

                                       7
<PAGE>
 
the currency of the country where the sale was made on which the royalty was
based, to the credit and account of DANA-FARBER or its nominee in any commercial
bank or trust company of DANA-FARBER's choice located in that country, prompt
notice of which shall be given by CENTOCOR EUROPE to DANA-FARBER.

authority, and CENTOCOR EUROPE shall furnish DANA-FARBER with proof of payment
of such tax together with official or other appropriate evidence issued by the
appropriate government authority sufficient to enable DANA-FARBER to support a
claim for federal income tax credit in respect of any sum so withheld.

     4.5  --   CENTOCOR EUROPE agrees to make written reports to DANA-FARBER
within ninety (90) days after the end of each calendar quarter commencing in the
quarter in which the first commercial sale occurs.  Each report shall state the
Net Sales of Licensed Products sold during such completed calendar quarter and
resulting calculation of earned royalty payment due DANA-FARBER pursuant to this
License Agreement for such completed calendar quarter.

     4.6  --   CENTOCOR EUROPE also agrees to make a written report to DANA-
FARBER within ninety (90) days after the date of termination of this License
Agreement, stating in such report the Net Sales of all Licensed Products sold
and upon which royalties


                                       8
<PAGE>
 
are payable hereunder but which were not previously reported to DANA-FARBER.

     4.7  --   CENTOCOR EUROPE agrees to keep records for a period of three (3)
years showing the Net Sales of Licensed Products in sufficient detail to enable
the royalties payable hereunder by CENTOCOR EUROPE to be determined, and further
agrees to permit its books and records to be examined by DANA-FARBER from time
to time to the extent necessary, but not more than once a year, to verify
reports provided for in Section 4.5 of this License Agreement.  Such examination
is to be made in accordance with generally accepted auditing standards by a firm

<PAGE>
 
identified as such in writing within thirty (30) days after its transmittal by
one party to another.

     6.3  --   If either party hereto contends that any such information subject
to this Article 6 is no longer entitled to be considered proprietary information
as a result of its having become part of the public domain without the fault of
such party, or having become known to such party as a result of its having been
received from a third party not subject to a binder of confidentiality, then
such circumstances shall be documented to such other party prior to any
disclosure of the information to third parties, and in timely manner to allow
the party who provided such information to object to such proposed disclosure.

     6.4  --   Nothing herein shall prevent CENTOCOR EUROPE or DANA-FARBER from
using its own proprietary information for their own purposes.

                                 7.  PUBLICITY

Dear Sarah:

I am writing to document our mutual agreement with respect to the licenses from
the Dana-Farber to Centocor for the DF3, CA 125, and SM1 antibodies.

With respect to DF3, we agree that Centocor now possesses an exclusive license
to the DF3 antibody for application in research, in vivo and in vitro-
                                                 -- ----     -- -----
diagnostics, and in therapy.  This license is world-wide.  While at the present
time there are no patents pertaining to DF3, your attorney will consider
preparation on an application on the assay or on the antigen recognized by DF3.
While this application may have investigators from the Dana-Farber as inventors
who will assign their rights in the invention to the Dana-Farber, Centocor shall
                                                                           -----
have an exclusive license to DF 3 rights under that patent under terms of the
                          ---------------------------------------------------
present agreement.
- ------------------

With respect to the OC 125 antibody, we agree that Centocor holds an exclusive
license for use of this antibody in research applications, in applications of in
                                                                              --
vitro and in vivo diagnosis, and for therapy in a non-conjugated form.  However,
- -----     -- ----                                                               
Centocor's license to the OC 125 antibody for use in human therapy in conjugated
form is non-exclusive, with immunoGen being the only other licensee with rights
to the OC 125 antibody inconjugates developed by ImmunoGen for human therapy.

With respect to the SM1 antibody I am pleased to confirm that the Dana-Farber
accepts the exercise by Centocor of its option to an exclusive license for SM1.
This exclusive license shall be for applications in research, in vitro and in
                                                              -- -----     --
vivo diagnostics, and for therapy in non-conjugated form.  The license to
- ----                                                                     
Centocor for use in human therapy in conjugated form shall be non-exclusive with
ImmunoGen holding a non-exclusive license for that particular purpose also.

For the use of the OC 125 and SM1 monocional antibodies in conjugated form for
human therapy, the Dana-Farber shall not grant to any parties other than
Centocor and ImmunoGen a license for commercial purposes.  That is, your
licensee and that given to ImmunoGen shall be semi-exclusive.

                                              Centocor/2

Finally I am pleased to indicate that the licenses for all three antibodies
provided by the Dana-Farber to Centocor shall be for the maximum period
permissible by law and regulation.

Thank you and best wishes.

                                    Sincerely,

                                    /s/ David Kiszkiss

which would prevent or impair the grant to CENTOCOR of the licenses granted
hereby, the exercise by CENTOCOR of the option to obtain licenses or the
exercise by CENTOCOR of such licenses, other than those imposed upon DANA-FARBER
by its grantee and/or contractor status under federal, philanthropic or non-
profit sponsorship.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained
and intending to be legally bound hereby, CENTOCOR and DANA-FARBER agree as
follows:

     ARTICLE I - PLAN FOR RESEARCH AND BUDGET
     ----------------------------------------

     1.01  CENTOCOR agrees to pay to DANA-FARBER funds to support research
relating to the above-mentioned Field and DANA-FARBER agrees to supply the
services of requisite personnel and to furnish the necessary facilities and to
carry out such research all according to an Annual Plan for Research and Budget
agreed upon by CENTOCOR and DANA-FARBER.

     1.02  DANA-FARBER, shall annually submit to CENTOCOR a proposed plan for
research and budget.  The Plan for Research for the first (lst) year of five (5)
years and the budget for the first year of this Agreement and projected budgets
for four subsequent years are set forth in Attachment A hereto.  The Plan for
Research for the second (2nd), third (3rd), fourth (4th) and fifth (5th) years
of this Agreement will be submitted ninety (90) days prior to the commencement
of each year.  The parties will negotiate in good faith and use their best
effort to agree upon the Plan for Research and CENTOCOR shall notify 
<PAGE>
 
                                      -3-

DANA-FARBER in writing of its acceptance of the Plan for Research submitted by
DANA-FARBER.

     1.03  For as long as they remain at DANA-FARBER, such research by DANA-
FARBER shall be under the direction of Dr. Robert Bast, Jr. and Dr. Robert C.
Knapp.  In addition, Dr. Robert Bast, Jr. and Dr. Robert C. Knapp will not
conduct research in the Field for other commercial organizations during the term
of this Agreement.

     1.04  In the event that the services of Dr. Robert Bast, Jr. become for any
reason unavailable during the course of this Agreement, the DANA-FARBER shall
have ninety (90) days within which to provide a replacement who shall be
acceptable to CENTOCOR.  Said replacement shall be upon the joint agreement of
the DANA-FARBER CANCER INSTITUTE and the Chiefs of Gynecology and Tumor
Immunology at DANA-FARBER.  CENTOCOR shall not unreasonably withhold acceptance
of such replacement.  In the event that no such replacement is provided, the
obligations of CENTOCOR to fund the Agreement shall cease.

     ARTICLE II - INVOLVEMENT OF HUMAN SUBJECT
     -----------------------------------------

     2.01  Before arranging for any clinical trial(s) involving medical
diagnostics and therapeutics of any development within the Field, CENTOCOR shall
first invite DANA-FARBER in writing to conduct such trial(s) during the period
of this Agreement and thereafter.  If DANA-FARBER agrees to conduct the
trial(s), DANA-FARBER will respond to CENTOCOR in writing by the thirtieth day
next following its receipt of the invitation; but nothing in the Agreement shall
be construed to require DANA-FARBER, if DANA-FARBER declines the invitation, to
conduct any clinical trial. All direct and indirect expenses of every clinical
trial of any Product shall be paid by CENTOCOR.

     2.02  If the clinical trials require multi-institutional participation,
prior written approval from the DANA-FARBER must 
<PAGE>
 
                                      -4-

be obtained by CENTOCOR before any invitation or overture to another Institution
to participate in the clinical trials is extended and CENTOCOR will notify and
discuss with DANA-FARBER and Drs. Bast and Knapp the shipment of antibody to
other investigators.

     2.03  At the time the Plan for Research involves the use of medical
therapeutics on human subjects, the budget for the time period involved will be
supplemented over and above that described in Appendix A to cover all patient
costs incurred due to this use.

     2.04  When human studies are directly sponsored by CENTOCOR in the Field,
CENTOCOR assumes any and all liability for injury to any human subject or
another person or persons or any other liability resulting from an in vivo use
                                                                   --         
conducted at the DANA-FARBER or otherwise, and CENTOCOR further agrees to
indemnify DANA-FARBER investigators and professional personnel for loss incurred
as a result of said in vitro and in vivo use conducted at DANA-FARBER or
                    -- -----     --                                     
otherwise provided that all in vitro and in vivo use when conducted at DANA-
                            -- -----     -- ----                           
FARBER will be conducted in accordance with the National Institute of Health
Guidelines in regard to the Rights and Protection of Human Subjects and where
appropriate, the Food and Drug Administration rules, regulations and guidelines
and the rules, regulations and guidelines of the Human Subjects Protection
Committee of the DANA-FARBER.  In connection with human studies, DANA-FARBER
agrees to assume any and all liability for injury to any human subjects
resulting from any act of omission of DANA-FARBER in conducting human studies.

     ARTICLE III - REPORTS BY DANA-FARBER
     ------------------------------------

     3.01  DANA-FARBER, through the efforts of BAST, shall provide annual
reports in writing to CENTOCOR, presenting a brief summary of the research

regarding its 
<PAGE>
 
                                      -5-

work in the Field. At the conclusion of each annual period or in the event of
termination of the Agreement, CENTOCOR shall receive a complete detailed report
of the work carried out and funded by this Agreement.

     ARTICLE IV - PAYMENTS BY CENTOCOR
     ---------------------------------

     4.01  CENTOCOR shall pay to DANA-FARBER                    [**]
Dollars            [**]      in the first year of this Agreement in support of
the research to be conducted.                      [**]         Dollars and
[**]   Cents      [**]        shall be paid upon the signing of this Agreement
and at quarterly intervals thereafter.

     4.02  The second year of the Agreement shall be paid at quarterly intervals
at a funding level of   [**]   , assuming reasonable progress and provided
CENTOCOR shall approve the Plan for Research for such year.

     4.03  The third year of the Agreement shall be paid in the same manner as
the second year and the funding level will be   [**]    , assuming reasonable
progress and provided CENTOCOR shall approve the Plan for Research for such
year.

     4.04  The fourth year of the Agreement shall be paid in the same manner as
the third year and the funding level will be       [**]   , assuming reasonable
progress and provided CENTOCOR shall approve the Plan for Research for such
year.

     4.05  The fifth year of the Agreement shall be paid in the same manner as
the fourth year and the funding level will be    [**]  , assuming reasonable
progress and provided CENTOCOR shall approve the Plan for Research for such
year.

     4.06  At each yearly anniversary of the Agreement, the parties shall
determine whether DANA-FARBER has made reasonable progress in the Field.  In the
event it is established that
<PAGE>
 
                                      -6-

reasonable progress has not been made, CENTOCOR, upon their option, may cease
the funding of the research upon ninety (90) days notice.  However, if the
parties disagree as to whether reasonable progress has been made, this issue
will be settled in accordance with Article XV, Arbitration.  During the period
of arbitration, CENTOCOR shall continue to fund the research on a monthly basis
prorating the yearly funding to a monthly amount up to a period of twelve (12)
months following the initiation of arbitration.

     ARTICLE V - ESTABLISHMENT OF DANA-FARBER PROPRIETARY POSITION
     -------------------------------------------------------------

     5.01 DANA-FARBER agrees to establish a proprietary position in the Field to
the extent possible by (i) applying, when appropriate, for patents in the United
States and abroad on inventions conceived and/or reduced to practice covering
the results of this research; (ii) maintaining information which is generated as
confidential know-how except to the extent that rights are reserved under
section 5.04 (ii) and (iii) obtaining title to inventions funded by Government
or third party support, whenever possible. CENTOCOR agrees that it shall bear
the cost of applying for any and all patents under section 5.01 and these costs
shall be deducted from future royalties. The choice of counsel shall be
agreeable to both CENTOCOR and DANA-FARBER.

     5.02 For inventions which are jointly conceived by DANA-FARBER and CENTOCOR
inventors, DANA-FARBER inventors shall assign their rights to DANA-FARBER and
CENTOCOR inventors shall assign their rights to CENTOCOR.

     5.03  CENTOCOR shall have the right to have all of the research conducted
and funded hereunder reviewed by patent counsel of its choice subject to the
provisions of paragraph 5.01 and shall have the right to apply for patent
protection throughout the world for any invention conceived solely or 
<PAGE>
 
                                      -7-

jointly by CENTOCOR personnel. All expenses incurred by CENTOCOR in applying for
patent protection relating to inventions conceived solely or jointly by CENTOCOR
personnel shall be borne totally by CENTOCOR and none of the expenses shall be
creditable against any future royalty payments due DANA-FARBER by CENTOCOR. At
DANA-FARBER's request, CENTOCOR shall also apply for patent protection on behalf
of DANA-FARBER for inventions conceived entirely by DANA-FARBER employees. If
CENTOCOR so applies for patent protection on behalf of DANA-FARBER, all expenses
incurred by CENTOCOR shall be creditable against future royalty payments due
DANA-FARBER from CENTOCOR.

     5.04 The DANA-FARBER recognizes that during the course of this Agreement it
may, on behalf of BAST, acquire from CENTOCOR trade secrets or information which
is confidential to CENTOCOR. CENTOCOR has a period of thirty (30) days after the
exchange of information to notify DANA-FARBER as to whether said information
given to DANA-FARBER is to be considered confidential. Accordingly, the DANA-
FARBER agrees as follows: (i) except in furtherance of the Agreement, DANA-
FARBER will not at any time, during or subsequent to this Agreement, disclose
any information or knowledge received from CENTOCOR which has been so designated
as being secret and confidential, except to the extent that such information was
previously known to the DANA-FARBER as shown by its written records or except to
the extent that such information is or becomes available to the public without
fault on the part of the DANA-FARBER; (ii) the DANA-FARBER and its employees
shall have the rights to publish or otherwise publicly disclose information
gained in the course of the Agreement subject to the provisions of 5.4 (i)
hereof provided it gives CENTOCOR draft of the disclosure (manuscript or
abstract) at least sixty (60) days in advance of such publication.

     5.05  DANA-FARBER retains the right to (i) use any of the cell lines,
antibodies or their improvements derived in part or
<PAGE>
 
                                      -8-

total from this Agreement free of cost for its own research; (ii) distribute the
antibodies, antibody compositions, cell lines, or somatic cell hybrids to others
engaged in non-commercial research, free of cost, under a written agreement that
the use will be restricted to non-commercial research and that provided
materials shall not be transferred or communicated to any third person for any
reason.

     ARTICLE VI - OPTION TO CENTOCOR
     -------------------------------

     6.01 In view of CENTOCOR's support for research hereunder and for research
which was subject to the October 18, 1981 Agreement, DANA-FARBER grants to
CENTOCOR a non-exclusive, world-wide, irrevocable royalty-bearing license under
all DANA-FARBER rights including patent rights (rights arising from patent
applications and/or issued patents) in this Field and funded under this
Agreement or the October 18, 1981 Agreement and DANA-FARBER know-how covering
products and/or methods arising out of this research. The royalty shall be [**]
of the NET selling price. The NET selling price shall mean the sales price of
products actually charged by CENTOCOR, its affiliates, or licensees in the Field
of this Agreement. In the event DANA-FARBER grants a license to any third party
with respect to the Field of interest which provides for a lower rate of
royalties with respect to the practice of such DANA-FARBER invention, the
royalty payable by CENTOCOR shall be reduced to the rate paid by the third
party. The DANA-FARBER further grants to CENTOCOR an option based on an
agreement negotiated in good faith by the parties to obtain, whenever possible
and desired by CENTOCOR, an exclusive, world-wide, royalty-bearing license in
the Field for a maximum period possible under any or all of said DANA-FARBER
patent rights and know-how to make, have made, use and/or sell products and to
practice methods developed in this research. If such option is exercised, the
royalty shall be [**] of the NET selling price, defined as previously noted.
Royalties shall be paid to the DANA-FARBER as long as the product is marketed by
CENTOCOR and/or by 
<PAGE>
 
                                      -9-

another corporation as noted in other areas of this Agreement CENTOCOR shall not
have the right to sublicense or assign its rights or delegate its obligations
under licenses resulting from this Agreement, without DANA-FARBER's prior
approval, except that CENTOCOR may assign this Agreement to an entity with which
it merges or consolidates or to a corporation of which it owns at least 50% of
the equity.

     6.02  If DANA-FARBER and CENTOCOR are unable to agree upon suitable terms
for any particular license, and DANA-FARBER has a bona fide offer of license
from a third party, CENTOCOR shall have the right to match this offer within one
(1) month from the date of notification of such offer from a third party and to
thereby receive the license upon the same terms in lieu of said third party.

     6.03 The DANA-FARBER further agrees, in view of CENTOCOR's support, to make
any somatic cell hybrids developed under this research program available for use
in medical diagnostics and therapeutics to CENTOCOR upon request or if to a
CENTOCOR's designee, then upon the agreement of the parties. If DANA-FARBER has
patent protection for such somatic cell hybrids, CENTOCOR shall have the right
to receive an exclusive, world-wide license to use each of said somatic cell
hybrids in the Field for a licensing fee of     [**]     Dollars     [**]     
per somatic cell hybrid line. Such license shall include the right to sublicense
these rights within the Field upon approval of DANA-FARBER which shall not be
unreasonably withheld.

     6.04  If CENTOCOR makes payment to one or more third parties under patents
and/or know-how which CENTOCOR reasonably believes covers a product or process
licensed hereunder, the payments due under this Agreement shall be reduced by
the amount of payments actually made to said third parties by CENTOCOR;
providing, however, that the payments from CENTOCOR to the DANA-FARBER due under
this Agreement shall not be
<PAGE>
 
                                      -10-


reduced, in any event, to less than [**] of the NET selling price due to such
payments to said third parties. The return of any payments to CENTOCOR because
of an invalidated patent or know-how in the public domain shall be paid to the
DANA-FARBER in an amount necessary to restore the reduced royalty payment.

     6.05  The option previously exercised by CENTOCOR pursuant to the October
18, 1981 Agreement and incorporated therein as Appendix C shall remain effective
and is therefore incorporated herein as Appendix B.

     ARTICLE VII - COMMERCIAL DEVELOPMENT
     ------------------------------------

     7.01  CENTOCOR shall use its best efforts, including such efforts of any or
all of its affiliates and licensees, commercially to develop, manufacture and
distribute products throughout the world.

     7.02  At intervals no longer than every twelve (12) months, CENTOCOR shall
report in writing to DANA-FARBER on progress made toward commercialization,
manufacturing and distribution of the products and royalties earned thereon, and
if at any time progress is not considered reasonable, DANA-FARBER may terminate

     the Licensed Patent, and unless Licensor shall within three months of the
     receipt of such notice either (i) cause such infringement to terminate
     or (ii) initiate legal proceedings against the infringer, Licensee may upon

     proceedings. Any recovery by licensee in such proceedings shall first be
     used to pay Licensee any amounts withheld during the pendency of the
     proceedings.  The balance shall be divided [**] percent to Licensee and
     [**] percent to Licensor.
C.   In the event one party shall initiate or carry on legal proceedings to
     enforce any Licensed Patent against an alleged infringer, the other party
     shall fully cooperate with and supply all assistance reasonably requested

             ARTICLE IV ---ESTABLISHMENT OF UA PROPRIETARY POSITION
             ------------------------------------------------------

     4.01 UA agrees to establish a proprietary position in the Field to the
extent possible by (i) applying, as required by Article 4.03, for patents in the
United States and abroad on inventions conceived and/or reduced to practice
arising from this Research; (ii) maintaining information which is generated as
confidential know-how except to the extent that rights are reserved under
Article 4.09 (ii), (iii) obtaining title to inventions funded by Government or
third party support, whenever possible and (iv) diligently protecting its patent
rights from infringement.  The choice of patent counsel shall be agreeable to
both UA and CENTOCOR.

     4.02 During the term of this Agreement, for inventions in the Field which
are conceived by UA inventors, UA inventors shall assign their rights to UA.
For inventions in the Field which are conceived by CENTOCOR inventors, CENTOCOR
inventors shall assign their rights to CENTOCOR.  For inventions in the Field
which are jointly conceived by UA and CENTOCOR inventors, UA inventors shall
assign their rights to UA and CENTOCOR inventors shall assign their rights to
CENTOCOR.

     4.03   UA shall promptly advise CENTOCOR, in writing, of each invention
conceived and/or reduced to practice arising from this Research.
Representatives of UA and CENTOCOR shall then discuss whether a patent
application or applications, pertaining to such invention, should be filed

E.AGR.ARKANSAS.R&L                   - 6 -
<PAGE>
 
and in which countries such application or applications should be filed.
Applications assigned solely to UA shall be filed by UA; applications assigned
solely to CENTOCOR shall be filed by CENTOCOR, and jointly assigned applications
shall be filed as mutually agreed upon by the parties.

     4.04 All patent costs incurred by UA, including, without limitation, the
costs of preparing, filing, prosecuting (including mutually agreed upon
interferences or oppositions), issuing or maintaining patent rights claiming an
invention filed by mutual agreement of the parties after the Effective Date
shall be reimbursed by CENTOCOR upon the receipt of UA's notice of payment of
such costs.  Such reimbursement shall be   [**]   percent   [**] creditable
against future royalty payments due UA from CENTOCOR, however, such credit shall
not exceed [**]  percent [**]   of the royalties payable in any one payment
period.  Such credits may be accrued and carried forward by Centocor until such
time as they may be taken in accordance with the foregoing sentence.

     4.05 With respect to any patent application filed by mutual agreement of
the parties, each patent application, office action, response to office action,
request for terminal disclaimer, and request for reissue or reexamination of any
patent issuing from such application shall be provided to CENTOCOR sufficiently
prior to the filing of such application, response or request to allow for review
and comment by CENTOCOR.

     4.06 In the event CENTOCOR is not interested in having a patent application
filed with respect to a particular

E.AGR.ARKANSAS.R&L                   - 7 -
<PAGE>
 
invention in a particular country, CENTOCOR shall advise UA of such fact within
ninety (90) days from the date on which the invention was disclosed to CENTOCOR
by UA or sooner if necessary to avoid the loss of patent rights.  UA, at its own
expense, may then file and prosecute such patent application in any country
where CENTOCOR elects not to file.

     4.07 In the event that UA does not wish to file a patent application with
respect to a particular invention or does not wish to file patent applications
with respect to specific countries, it shall without delay notify CENTOCOR, and
CENTOCOR shall be free, where not contrary to United States law, to file at its
expense, patent applications in the name of UA, if necessary, and UA shall
render CENTOCOR, at CENTOCOR's expense, all necessary assistance in order to
facilitate such filing.

     4.08 CENTOCOR shall have the right to have all of the Research
conducted and funded hereunder reviewed by patent counsel of its choice subject
to the provisions of Articles 4.01 and 4.03.

     4.09 UA recognizes that during the course of this Agreement it may, on
behalf of Dr. O'Brien, acquire from CENTOCOR trade secrets or information which

     5.01 In view of CENTOCOR's support for research hereunder, UA hereby grants
to CENTOCOR and CENTOCOR hereby accepts an exclusive, world-wide, royalty-
bearing license with the right to grant sublicenses, under any and all patent
rights and know-how owned by UA relating to cell lines or hybridomas developed
by or under the direction of or in collaboration with Dr. Timothy O'Brien which
produce antibodies directed against antigens having the epitope recognized by OC
125 (the "Licensed Field") and the exclusive right to use said cell lines or
hybridomas for the purpose of

E.AGR.ARKANSAS.R&L                   - 9 -
<PAGE>
 
making, having made, using and/or selling products for in-vitro diagnostic
application.  Such exclusive license and right shall be for a period fifteen
(15) years or the life of any and all UA-owned rights in the Licensed Field,
whichever is greater.  The royalty rate shall be   [**]   percent  [**]  of the
NET selling price of products utilizing any UA rights licensed to Centocor
herein.  NET selling price shall be defined to mean the sales price of products
actually charged by CENTOCOR, its affiliates, or licensees for sales of products
on which a royalty is owed to UA hereunder, after deduction of customary trade
and quantity discounts actually allowed, credits or refunds actually allowed for
spoiled, damaged, outdated, or returned goods, sales and other excise taxes
imposed and paid directly with respect to the sales, and transportation costs to
the extent separately invoiced.

     5.02 UA further grants to CENTOCOR hereunder a right of first refusal to
obtain an exclusive worldwide royalty bearing license in the Field to make, have
made, use and/or sell products for in-vivo diagnostic or therapeutic
applications.  Said option shall be exercisable at Centocor's sole discretion
during the    [**]   period commencing with the date of receipt by CENTOCOR from
UA of a viable cell line in Licensed Field upon payment to UA of   [**]  .  The
royalty rate for such in-vivo products shall be [**]  percent  [**]  of the NET
selling price.

     5.03 If CENTOCOR makes payment to one or more third parties under patents
and/or know-how which CENTOCOR reasonably believes covers a product or process
licensed hereunder, the payments due under this Agreement shall be reduced by
the amount of payments actually owed to said third parties by

E.AGR.ARKANSAS.R&L                   - 10 -
<PAGE>
 
CENTOCOR; providing, however, that the payments from CENTOCOR to UA due under
this Agreement shall not be reduced, in any event, to less than  [**]  percent
[**]  of the royalties that would have been due in any period except for such
payments to said third parties.  The return by any such third parties of any
payments to CENTOCOR because of an invalidated third-party patent shall be paid
to UA in an amount necessary to restore any such reduced royalty payments.

5.04 In the event CENTOCOR or a sublicensee of CENTOCOR incurs attorney fees and
related legal expenses in judicial or administrative proceedings based upon
allegations of infringement of third party patents or know-how as a result of
the exercise of rights hereunder, or in the enforcement or defense of patents or
technology licenses hereunder, all such expenses will be offset against future
royalties due from CENTOCOR under this Agreement provided that such offsets do
not exceed [**]   percent [**] of the royalties due in any period.

any or all of its affiliates and licensees, to develop, manufacture and
distribute commercially feasible products utilizing rights licensed to Centocor
hereunder throughout the world.

     6.02 At intervals no longer than every twelve (12) months, CENTOCOR shall
report in writing to UA on progress made toward commercialization,

E.AGR.ARKANSAS.R&L                   - 11 -
<PAGE>
 
manufacturing and distribution of the products and royalties earned thereon, and
if at any time progress is not considered reasonable, UA may give notice to
CENTOCOR that CENTOCOR is in default and according to the provisions of Article
9.02, CENTOCOR shall formulate a plan and notify UA of such plan within thirty
(30) days of receipt of such notice to cure such default.  Approval of such plan
by UA shall be deemed to cure any such default pursuant to Article 9.02.

     6.03 CENTOCOR agrees to use nomenclature specified by Dr. O'Brien, unless
otherwise authorized in writing by UA, to identify the hybridomas for the
purposes of publication, promotion and commercial development of the hybridomas,
but shall not identify either UA, nor Dr. 0'Brien, nor his UA collaborators as
being the source of the antibodies and/or hybridomas; except that any
publication may refer to the published record.

                        ARTICLE VII - EFFECTIVE AND TERM
                        --------------------------------

<PAGE>
 
refusal to support said other program on terms to be determined by good faith
negotiations between the parties or upon the same terms and conditions that any
third party has agreed to and to thereby receive the same benefits as UA had
agreed to provide in return for said third party's support.  CENTOCOR shall
provide written notice to UA within one (1) month of such notification stating
whether CENTOCOR wishes to exercise this right of first refusal.

                            ARTICLE IX - TERMINATION
                            ------------------------

     9.02 Failure by UA or CENTOCOR to comply with any of the respective
obligations and conditions contained in this Agreement shall entitle the other
party to give to the party in default notice requiring it to cure such default.
If such default is not cured or a plan for cure has not been approved, such
approval to not be unreasonably withheld, within ninety (90) days after receipt
of such notice, the notifying party shall be entitled (without prejudice to any
of the other rights conferred on it by this Agreement) to terminate this
Agreement by giving notice to take effect immediately.  The right of either
party to terminate this Agreement as herein above provided shall not be affected
in any way by its waiver of, or failure to take action with respect to, any
previous default.

     9.03 In the event that one of the parties shall go into liquidation, or a
receiver, custodian or trustee be appointed for the property or estate of that
party, or the party makes an assignment for the benefit of creditors, and
whether any of the aforesaid events be the outcome of the voluntary act of that
party, or otherwise, the other party shall be entitled to terminate this
Agreement forthwith by giving written notice to the first party.

     9.04 Termination or expiration of the Agreement, other than under Articles
9.02 and 9.03, shall not affect rights and obligations of either party or the
licenses granted under Article V.

performance of any obligation hereunder by reason of Force Majeure

E.AGR.ARKANSAS.R&L                   - 14 -
<PAGE>
 
including an act of God, fire, flood, war (declared or undeclared), public
disaster, strike or labor differences, governmental enactment, rule or
regulation, or any other cause beyond such party's control, such party shall not
be liable to the other therefor; and the time for performance of such obligation
shall be extended for a period equal to the duration of the contingency which
occasioned the delay, interruption or prevention.  The party invoking such Force
Majeure rights under this Article must notify the other party by registered
letter within a period of fifteen (15) days, from the first and the last day of
the Force Majeure unless the Force Majeure renders such notification impossible
in which case notification will be made as soon as possible.  If the delay
resulting from the Force Majeure exceeds six (6) months, the injured party may
terminate this Agreement as per the conditions stipulated herein.

                          ARTICLE X - INDEMNIFICATION

     5.04 Prior to granting any additional, non-exclusive license to any third
party in the Field, UTHSC hereby agrees to promptly notify CENTOCOR of such
impending event.  CENTOCOR shall then have the right to exercise its option to
obtain an exclusive, worldwide, royalty-bearing license in the Field.  If
CENTOCOR fails to respond to UTHSC's notice within sixty (60) days, then UTHSC
may grant additional, non-exclusive licenses to one or more third parties in the
Field.

     5.05 If pursuant to Article 5.04, UTHSC shall grant a non-exclusive license
to any third party in the Field which provides for a lower rate of royalties

be mutually acceptable to both UTHSC and CENTOCOR.  Such acceptance shall not be
unreasonably withheld, and CENTOCOR and UTHSC shall divide any and all proceeds
from said sub-licenses on an equal basis.

     5.08 If CENTOCOR makes payment to one or more third parties under patents
and/or know-how which CENTOCOR reasonably believes covers a product or process
licensed hereunder, the payments due under this Agreement shall be reduced by
the amount of payments actually made to said third parties by CENTOCOR;
providing, however, that the payments from CENTOCOR to UTHSC due under this
Agreement shall not be reduced, in any

event, to less than   [**]   percent   [**]   of the royalties that would have
been due in any period except for such payments to said third parties.  The
return by any such third parties of any payments to CENTOCOR because of an
invalidated third-party patent shall be paid to UTHSC in an amount necessary to
restore any such reduced royalty payments.

     5.09 In the event CENTOCOR or a sublicensee of CENTOCOR incurs expenses in
judicial or administrative proceedings based upon allegations of infringement of
third party patents or know-how as a result of the exercise of rights hereunder,
or in the enforcement or defense of patents or technology licenses hereunder,
all such expenses will be offset against future royalties due from CENTOCOR
under this Agreement provided that such offsets do not exceed    [**]   percent
[**]   of the royalties due in any period.

Dear Jack:

     As our work with Dr. McEver's antibodies progresses, particularly with S-
12, we would like to hereby exercise the option under Article 5.01 of the
October 1, 1986 University of Texas Health Science Center at San Antonio -
Centocor Research and Licensing Agreement (the "Agreement") to convert our
License thereunder to exclusive.  Accordingly, the higher exclusive royalty
rates and other obligations related to the exclusive license as specified in
said Agreement shall become effective as of the date of this letter.

     As a clarification of further terms of Article 5.01, given that Dr. McEver
has left your institution and that we are continuing to fund him at the
University of Oklahoma, Centocor would like to propose that the minimum royalty
payments discussed in Article 5.01 commence on October 1, 1989, the third
anniversary of the Agreement.  This is in line with the expected three years of
funding originally envisioned under Article I of the Agreement.  Dr. McEver's
departure was obviously not foreseen when said Article was drafted.

     If this above modifications/clarifications to the Agreement are acceptable,
please have both copies of this letter signed by your institution and return one
to me.

     Feel free to call all with any questions.

Very truly yours,
/s/ Sarah A. Shoaf

Director of Corporate Technology Affairs

Centocor shall have the option, following the expiration of any grace or cure
periods provided in such applicable Section, in lieu of such termination and
upon written notice to Biometric (the "Conversion Notice"), to terminate only
certain provisions of this Agreement.  Upon delivery of the Conversion Notice
(i) Sections 3.1, 3.2, 3.3, 3.4, 4.1, 4.2 and 6.1 hereof and (ii) Biometric's
obligations under Section 5 hereof, shall terminate with no further force or
effect, except for the satisfaction of any obligations which accrued prior to

possible which will be filed in any patent office, and providing the other
copies of any substantive documents that such party receives from such patent
offices promptly after receipt, including notice of all interferences, reissues,
re-examinations, oppositions or requests for patent term extensions. Centocor
and Biometric shall each reasonably cooperate with and assist the other at its
own expense in connection with such activities, at the other party's request.

WARRANTY:
- -------- 

Standard Instrument Warranty.  Biometric Imaging, Inc. ("Biometric") warrants
- ----------------------------                                                 
that, subject to the exclusions set forth in this Warranty, that the IMAGN(R)
2000 instrument ("IMAGN") shall substantially conform to the material functional
specifications contained in the IMAGN Operator's Guide for one (1) year from the
date of delivery to the original end user purchaser ("End User") as evidenced by
the End User's bill of lading.  The foregoing warranty is contingent upon proper
use of the IMAGN in the applications for which it was intended as indicated in
the IMAGN Operator's Guide.  The above limited warranty applies only to
reproducible defects reported to Biometric in accordance with Biometric's
standard reporting procedures described in the IMAGN Operator's Guide and do not
apply to (A) beta or preproduction versions of the IMAGN (including the software
contained therein), and (B) third party hardware or software not sold by
Biometric for use with the IMAGN, or (C) to any IMAGN which after shipment by
Biometric (i) has been altered, except by Biometric or under and in full
compliance with Biometric's direction, or (ii) has not been installed, operated,
repaired, or maintained in accordance with any installation, handling,
maintenance or operating instructions supplied by Biometric, or (iii) has been
damaged by unusual physical or electrical stress, negligence, or accident, or
(iv) has been damaged by acts of nature, vandalism, burglary, neglect, or
misuse, or (v) has not been updated with all error corrections and bugs fixes
provided by Biometric.  In the event of any breach of the warranty set forth
above, the End User's exclusive remedy and Biometric's sole and exclusive
liability shall be, at Biometric's sole discretion, (x) with respect to hardware
portions of the IMAGN, to repair or replace the IMAGN at Biometric's expense
within thirty (30) days after the nonconformity is reported to Biometric, and
(y) with respect to software portions of the IMAGN, either (i) to use
commercially reasonable efforts to correct the conformity within thirty (30)
days after the nonconformity is reported to Biometric, provided that the End
User notifies Biometric in a timely manner in writing that such IMAGN failed to
conform and furnishes a detailed explanation of any alleged nonconformity, or
(ii) if such efforts fail to correct the nonconformity within such thirty (30)
day period, and such nonconformity materially affects the operation or
performance of the IMAGN, or if Biometric otherwise elects, to promptly (x)
replace the IMAGN with conforming software at Biometric's expense, or (y)
provide the End User with a refund of the invoice price of each IMAGN affected
by such nonconformity.

Return of an IMAGN.  To return an IMAGN that fails to conform to the limited
- ------------------                                                          
warranty set forth above, the End User shall first obtain a Return Material
Authorization ("RMA") number from Biometric by calling Biometric's telephone
support number.  If any IMAGN is returned without an RMA number, Biometric











                                     -32-


































reserves the right to refuse to accept such IMAGN.  Within seven (7) days of
receipt of the RMA number, the End User shall return to Biometric the IMAGN,
freight prepaid, in its original shipping carton or other appropriate crating
with the RMA number displayed visibly on the outside of the carton F.O.B.
Biometric's address or such other location as Biometric may designate in
writing. Biometric will reimburse for shipment charges for return of a
nonconforming IMAGN.

Disclaimer of Other Warranties.  EXCEPT FOR THE LIMITED WARRANTIES PROVIDED

ABOVE, BIOMETRIC AND ITS THIRD PARTY SUPPLIERS GRANT NO OTHER WARRANTIES  OR
CONDITIONS, EXPRESS OR IMPLIED, BY STATUTE, OR OTHERWISE, REGARDING THE IMAGN
(INCLUDING THE SOFTWARE CONTAINED THEREIN) OR THE ASSAY CARTRIDGES, AND
BIOMETRIC AND ITS THIRD PARTY SUPPLIERS SPECIFICALLY DISCLAIM THE IMPLIED
WARRANTIES FOR FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY, AND
NONINFRINGEMENT. BIOMETRIC DOES NOT WARRANT THAT OPERATION OF THE IMAGN WILL BE
UNINTERRUPTED OR ERROR-FREE.  ANY OTHER REPRESENTATIONS OR WARRANTIES MADE BY
ANY PERSON OR ENTITY, INCLUDING EMPLOYEES OR REPRESENTATIVES OF BIOMETRIC, THAT
ARE INCONSISTENT HEREWITH SHALL BE DISREGARDED AND SHALL NOT BE BINDING UPON
BIOMETRIC OR ITS THIRD PARTY SUPPLIERS. IN NO EVENT SHALL BIOMETRIC BE LIABLE TO
THE END USER, OR ANY THIRD PARTY FOR LOST PROFITS, OR FOR ANY SPECIAL,
CONSEQUENTIAL, INCIDENTAL, OR INDIRECT DAMAGES FOR BREACH OF WARRANTY. THIS
LIMITATION SHALL APPLY EVEN WHERE BIOMETRIC HAS BEEN ADVISED OR THE POSSIBILITY
OF SUCH DAMAGE AND NOTWITHSTANDING THE FAILURE OF THE ESSENTIAL PURPOSE OF ANY
LIMITED REMEDY STATED HEREIN.
