PARTI
ITEM 1. DESCRIPTION OF BUSINESS

Northfield  Laboratories Inc. ("Northfield" or the "Company") believes it is a
leader in the development of a safe and effective alternative to transfused
blood for use in the treatment of acute blood loss. The Company's PolyHeme(TM)
blood substitute product is a solution of chemically modified hemoglobin
derived from human blood. Clinical studies to date indicate that PolyHeme
carries as much oxygen, and loads and unloads oxygen in the same manner, as
transfused blood. Infusion of PolyHeme also restores blood volume. Therefore,
PolyHeme should be effective as an oxygen-carrying resuscitative fluid in
the treatment of hemorrhagic shock resulting from extensive blood loss. The
Company's method of manufacturing PolyHeme is designed to eliminate the risk of
transmission of diseases such as AIDS or hepatitis. Clinical studies to date
indicate that PolyHeme is universally compatible and accordingly should not
require blood typing prior to infusion. Therefore, PolyHeme should be available
for immediate use in emergency situations. In addition, PolyHeme has an
extended shelf life compared to blood.

The Company is presently conducting Phase III clinical trials of PolyHeme at
multiple locations in the United States. The Company and its European partner,
Pharmacia & Upjohn AB, are also seeking the necessary approvals to begin Phase
III clinical trials of PolyHeme at multiple sites in the United Kingdom,
Germany and Sweden. The Company's Phase III clinical protocol is a randomized
controlled study in which elective surgical patients are infused with up to six
units of PolyHeme (three liters containing 300 grams of hemoglobin). The
Company believes it is the only firm to report successful infusion of high
doses of a blood substitute in any phase of clinical testing.

The Company is also continuing to conduct Phase II clinical trials of PolyHeme
in trauma and emergency surgical applications. Since September 1996, the
Company has been authorized by the Food and Drug Administration (the "FDA") to
infuse patients in its Phase II trials with up to ten units (500 grams) of
PolyHeme. This unprecedented dose is equivalent to replacing the entire blood
volume of an average person. To date, more than 15 patients have successfully
been infused with the maximum ten unit dosage. The Company recently received
permission from the FDA to double  the maximum dose in its Phase II trials to
20 units (1,000 grams) of PolyHeme.

Infusions have been given during resuscitation, intraoperatively and
postoperatively. The rate of infusion has varied with the clinical setting. The 
most rapid rate consisted of the infusion of ten units in 20 minutes during
rapid hemorrhage. No adverse effects attributed to the infusion of PolyHeme
have been observed. The results of the Company's ongoing clinical trials have
been presented to the American Association for the Surgery of Trauma and the
American College of Surgeons, and have been published in the September 1997
issue of the Journal of Trauma and the August 1998 issue of the Journal of the
American College of Surgeons, both peer-reviewed scientific journals.

In August 1998, the FDA requested that the Company expand the number of
patients in its Phase III clinical trials. Although the Company's Phase III
trials have progressed without negative incident, the FDA based its request on
what it characterized as public concern over failures of competing blood
substitute products in Phase III trials. The Company's Phase III protocol
earlier approved by the FDA included 240 elective surgery patients. At present,
the Company and the FDA have agreed that at least 600 patients would need to
participate in an expanded study.

                                   BACKGROUND

The principal function of  human blood is to transport oxygen throughout the
body. The lack of an adequate supply of oxygen as a result of blood loss can
lead to organ dysfunction or death. The transfusion of human blood is presently
the only effective means of immediately restoring diminished oxygen-carrying
capacity resulting from blood loss. The Company estimates that approximately 14
million units of blood were transfused in the United States in 1997, of which
approximately 8.5 million units were administered to patients suffering the
effects of acute blood loss.

The use of donated blood in transfusion therapy, while effective in restoring
an adequate supply of oxygen in the body of the recipient, has several
limitations. Although  testing  procedures exist to detect the presence of
certain diseases in blood, these procedures cannot eliminate completely the
risk of  blood-borne disease. Transfused blood also can be used only in
recipients having a blood type compatible with that of the donor. Delays
in treatment resulting from the necessity of blood typing prior to transfusion,
together with the limited shelf life of  blood and the limited availability of
certain blood types, impose constraints on the immediate availability of
compatible blood for transfusion. There is no commercially available blood
substitute which addresses these problems.

Northfield's scientific research team has been responsible for the original
concept, the early development and evaluation and clinical testing of PolyHeme,
and have authored over 100 publications in the scientific literature relating
to human blood substitute research and development. Members of the scientific
research team have been involved in development of national transfusion policy
through their participation in the activities of the National Heart Lung Blood  
Institute, the National Blood Resource Education Panel, the Department of
Defense, the American Association of Blood Banks, the American Blood
Commission, the American College of Surgeons and the American Red Cross. 

                                  THE PRODUCT

PolyHeme is a solution of chemically modified hemoglobin-derived from human
blood. Hemoglobin is the oxygen-carrying component of the human red blood cell.
Northfield purchases donated blood from The American Red Cross and Blood
Centers of America for use as the starting material for PolyHeme. The Company
uses a proprietary process of separation, filtration and chemical modification
to produce PolyHeme. Hemoglobin is first extracted from red blood cells and
filtered to remove impurities. The purified hemoglobin is next chemically
modified using a multi-step process to create a polymerized form of hemoglobin
designed to avoid the undesirable effects historically associated with
hemoglobin-based blood substitutes, including vasoconstriction, kidney
dysfunction, liver dysfunction and gastrointestinal distress.  The modified
hemoglobin is then incorporated into a solution which can be administered as an
alternative to transfused blood. One unit of PolyHeme contains 50 grams of
modified hemoglobin, approximately the same amount of hemoglobin delivered by
one unit of transfused blood.

PolyHeme is intended for use as an alternative to transfused blood in the
treatment of acute blood loss. Clinical studies to date indicate that PolyHeme
carries as much oxygen, and loads and unloads oxygen in the same manner, as
transfused blood. Infusion of PolyHeme also restores blood volume.  Therefore,
PolyHeme should be effective as an oxygen-carrying resuscitative fluid in the
treatment of hemorrhagic shock resulting from extensive blood loss.

In addition to its utility as an oxygen carrier and blood volume expander, the
Company believes PolyHeme will have the following additional benefits:

ELIMINATION OF DISEASE TRANSMISSION. Northfield believes, and laboratory and
clinical tests have thus far indicated, that the manufacturing process used to
produce PolyHeme eliminates blood-borne diseases, such as AIDS and hepatitis,
which may be present in transfused blood.








Northfield Laboratories Inc. (a company in the development stage)

UNIVERSAL COMPATIBILITY.  Clinical studies to date indicate that PolyHeme is
universally compatible  and accordingly should not require blood typing prior
to use. The benefits of universal compatibility include the ability to use
PolyHeme immediately, the elimination of transfusion reactions due to mistakes
in blood typing, and the reduction of the inventory burden associated with
maintaining sufficient quantities of blood types having limited availability.

EXTENDED SHELF LIFE.  The Company believes PolyHeme has a shelf life well in
excess of the 28 to 42 days currently permitted for blood.  The Company
estimates PolyHeme has a shelf life of approximately 12 months under
refrigerated conditions.

                                   THE MARKET

The Company estimates that approximately 14 million units of blood were
transfused in the United States in 1997, of which approximately 8.5 million
units were administered to patients suffering the effects of acute blood loss.
Patient charges for the units of blood used in the United States in 1997 for
the treatment of acute blood loss were approximately $2.5 billion. The
transfusion market in the United States consists of two principal segments. The
acute blood loss segment, which comprises approximately 60% of the transfusion
market, includes transfusions required in connection with trauma, surgery and
unexpected blood loss. The chronic blood loss segment represents approximately
40% of the transfusion market and includes transfusions in connection with
general medical applications and chronic anemias.


PolyHeme is intended for use as an alternative to transfused blood in the
treatment of acute blood loss. The two principal clinical settings in which
patients experience acute blood loss are elective surgery and non-elective,
emergency surgery. Elective surgery represents the largest potential market for
PolyHeme, with approximately 6.5 million units of blood being used in the
United States each year. The major benefit of PolyHeme in this setting is
expected to be increased transfusion safety for patients and health care
professionals. In addition, approximately two million units of blood are used
in the United States each year for emergency surgical procedures. In this
setting, the immediate availability and universal compatibility of PolyHeme is
expected to provide significant advantages over transfused blood by avoiding
the delay and opportunities for error associated with blood typing.

In addition to the foregoing applications for which blood is currently used,
there exist potential sources of demand for which blood is not currently
utilized and for which PolyHeme may be suitable. These include applications in
which the required blood type is not immediately available or in which
transfusions are desirable but not given for fear of a transfusion reaction due
to difficulty in identifying compatible blood. For example, the Company
believes emergicenters and surgicenters both experience events where an
oxygen-carrying volume expander may be useful. The Company also believes
PolyHeme may be used by Emergency Medical Technicians in ambulances, medical
helicopters and other prehospital settings. In addition, the military has
expressed a high level of interest in oxygen-carrying products for the
resuscitation of battlefield casualties.

                                CLINICAL TRIALS

Infusions have been given during resuscitation, intraoperatively and
postoperatively. The rate of infusion has varied with the clinical setting. The
most rapid rate consisted of the infusion of ten units in 20 minutes during
rapid hemorrhage. No adverse effects attributed to the infusion of PolyHeme
have been observed. The results of the Company's ongoing clinical trials have
been presented to the American Association for the Surgery of Trauma and the
American College of Surgeons, and have been published in the September 1997
issue of the Journal of Trauma and the August 1998 issue of the Journal of the
American College of Surgeons, both peer-reviewed scientific journals.

                           PHASE III CLINICAL TRIALS

The Company is presently conducting Phase III clinical trials of PolyHeme at
multiple locations in the United States. The Company's Phase III clinical
protocol is a randomized controlled study in which elective surgical patients
are infused with up to six units of PolyHeme (three liters containing 300 grams
of hemoglobin). The Company believes it is the only firm presently conducting
Phase III clinical trials of a blood substitute product and the only firm to
report successful infusion of high doses of a blood substitute in any phase of
clinical testing.

The Company has engaged an international contract research organization to
independently administer the collection of patient data generated by test sites
participating in the Company's Phase III clinical trials. The purpose of
independent administration is to ensure that data collected as part of Phase
III trials is free from any inaccuracy or bias that might result from
interactions between the testing sites and the trial sponsor. As a result of
this arrangement, the Company will not have access to detailed information
regarding the status or results of its Phase III clinical trials until patient
enrollment is completed.

The Company and its European partner, Pharmacia & Upjohn AB, are seeking the
necessary approvals to begin Phase III clinical trials of PolyHeme at multiple
sites in the United Kingdom, Germany and Sweden. The European trials will use
the same clinical protocol as the Company's Phase III trials in the United
States.

In August 1998, the FDA requested that the Company expand the number of
patients in its Phase III clinical trials. Although the Company's Phase III
trials have progressed without negative incident, the FDA based its request on
what it characterized as public concern over failures of competing blood
substitute products in Phase III trials. The Company's Phase III protocol
earlier approved by the FDA included 240 elective surgery patients. At present,
the Company and the FDA have agreed that at least 600 patients would need to
participate in an expanded study.

                            PHASE II CLINICAL TRIALS

In addition to its Phase III trials, the Company is continuing to conduct Phase
II clinical trials of PolyHeme in trauma and emergency surgical applications at
civilian hospitals and military medical facilities in the United States. These
continuing clinical trials, which began in 1994, are designed to assess the
safety and effectiveness of PolyHeme in treating acute blood loss and
hemorrhagic shock in trauma and surgical patients. When the treating physicians
participating in the Company's clinical trials determine a blood transfusion is
indicated, the infusion of PolyHeme is initiated in place of donated blood.

Since September 1996, the Company has been authorized by the FDA to infuse
patients in its Phase II trials with up to ten units (500 grams) of PolyHeme.
This unprecedented dose is equivalent to replacing the entire blood volume of
an average person. To date, more than 15 patients have successfully been
infused with the maximum ten unit dosage. The Company recently received
permission from the FDA to double  the maximum dose in its Phase II trials to
20 units (1,000 grams) of PolyHeme.

                      MANUFACTURING AND MATERIAL SUPPLY

The Company uses a proprietary process of separation, filtration and chemical
modification to produce PolyHeme. Since 1990, the Company has produced PolyHeme
it its 21,000 square foot pilot manufacturing facility. The Company believes
this facility is capable of producing sufficient quantities of PolyHeme for all
of the Company's clinical trials in the United States and Europe. The Company
and its independent engineering consultants believe the Company's existing
manufacturing process may be scaled up without substantial modification to
produce commercial quantities of PolyHeme in larger facilities.




Northfield Laboratories Inc. (a company in the development stage)


<PAGE>   7




If FDA approval of PolyHeme is received, the Company presently intends to
manufacture PolyHeme for commercial sale in the Unites States using its own
facilities. The Company currently has licensing arrangements for the
manufacture of PolyHeme in certain countries outside the United States. The
Company is also considering entering into other collaborative relationships
with strategic partners which could involve arrangements relating to the
manufacture of PolyHeme.

The successful commercial introduction of PolyHeme will also depend on an
adequate supply of blood to be used as a starting material. Northfield believes
that an adequate supply of blood is obtainable through the voluntary blood
services sector. The Company has had extensive discussions with existing blood
collection agencies, including The American Red Cross and Blood Centers of
America, regarding sourcing of  blood. The Company currently has short-term
purchasing contracts with each of these agencies. In 1996, the Company entered
into an agreement with hemerica, Inc., a subsidiary of Blood Centers of America
("hemerica"), under which hemerica will supply Northfield with 82,500 units per
year of packed red cells, the source material for PolyHeme, over a three year
period. Northfield has and will continue to pursue long-term supply contracts
with such agencies and other potential sources, although there can be no
assurance that the Company will be able to obtain sufficient quantities of
blood from the voluntary blood services sector to enable it to produce
commercial quantities of PolyHeme if FDA approval is received.  See "Risk
Factors - Limitation of Supply of Starting Material."


                              MARKETING STRATEGIES

If FDA approval of PolyHeme is received, the Company intends to market PolyHeme
with its own sales force in the United States. The Company intends to recruit
and train a specialty sales force of approximately 20 individuals to introduce
PolyHeme in selected markets. The selling effort will target approximately 500
hospitals which utilize over 70% of the nation's blood supply. The Company
believes the most important marketing activities will be educating, stimulating
use by and servicing health care professionals.

The Company may pursue licenses or other arrangements for the manufacture and
distribution of PolyHeme outside the United States. The Company has entered
into license agreements with Pharmacia & Upjohn AB, ("Pharmacia"), and Hemocare
Ltd., an Israeli corporation ("Hemocare"), to develop, manufacture and
distribute PolyHeme in certain European, Middle Eastern and African countries.
The license agreements permit Pharmacia and Hemocare to utilize PolyHeme and
related manufacturing technology in return for the payment of royalties based
upon sales of PolyHeme in the licensed territories.

In March 1989, the Company granted to Pharmacia an exclusive license to
manufacture, promote and sell the Company's PolyHeme product in a territory
encompassing the United Kingdom, Germany, the Scandinavian countries and
certain countries in the Middle East. Under the terms of the license agreement,
Pharmacia has the right, upon consultation with the Company, to promote and
sell PolyHeme in the licensed territory under its own trademark. The license
agreement with Pharmacia provides for a nonrefundable initial fee, two  
additional nonrefundable fees based upon the achievement of certain regulatory
milestones by the Company, and ongoing royalty payments based upon net sales of
PolyHeme in the licensed territory. The license agreement further provides for
a reduction of royalty payments upon the occurrence of certain events. In
addition, under the terms of the agreement, the Company has the right under
certain circumstances to direct Pharmacia's clinical testing of PolyHeme in the
licensed territory. The Company recently announced that it and its European
partner, Pharmacia & Upjohn AB, an affiliate of Pharmacia, are seeking the
necessary approvals to begin Phase III clinical trials of PolyHeme at multiple
sites in the United Kingdom, Germany and Sweden.

In July 1990, the Company granted to Hemocare an exclusive license to
manufacture, promote and sell the Company's PolyHeme product in a territory
encompassing Israel, Cyprus, Ivory Coast, Jordan, Kenya, Lebanon, Liberia,
Nigeria and Zaire. Under the terms of the license agreement, Hemocare has the
right, upon consultation with the Company, to promote and sell PolyHeme in the
licensed territory under its own trademark. The license agreement with Hemocare
provides for royalty payments based on net sales of PolyHeme in the licensed
territory. In addition, under the terms of the license agreement, the Company
has the right under certain circumstances to direct Hemocare's clinical testing
of PolyHeme in the licensed territory.

Northfield's present plans with respect to the marketing and distribution of
PolyHeme in the United States and overseas may change significantly based on
the results of the clinical testing of PolyHeme, the establishment of
relationships with strategic partners, changes in the scale, timing of cost of
the Company's commercial manufacturing facility, competitive and technological
advances, the FDA regulatory process, the availability of additional funding
and other factors.

                                  COMPETITION

If approved for commercial sale, PolyHeme will compete directly with
established therapies for acute blood loss and may compete with other
technologies currently under development. There can be no assurance that
PolyHeme will have advantages which will be significant enough to cause medical
professionals to adopt it rather than to continue to use established therapies
or other new technologies or products. There can also be no assurance that the
price of PolyHeme, in light of PolyHeme's potential advantages, will be
competitive with the price of established therapies or other new technologies
or products.

Northfield believes that the treatment of acute blood loss is the setting most
likely to lead to FDA approval and the application which presents the greatest
market opportunity.  However, several companies have developed or are in the
process of developing technologies which are, or in the future may be, the
basis for products which will compete with PolyHeme. Certain of these companies
are pursuing different approaches or means of accomplishing the therapeutic
effects sought to be achieved through the use of PolyHeme.  Many of these       
companies have substantially greater financial resources, larger research and
development staffs, more extensive facilities and more experience than
Northfield in testing, manufacturing, marketing and distributing medical
products. There can be no assurance that one or more other companies will not
succeed in developing technologies and products which will be available for
commercial use prior to PolyHeme, which will be more effective or less costly
than PolyHeme or which would otherwise render PolyHeme obsolete or
noncompetitive.

The Company believes that important competitive factors in the market for blood
substitute products will include the relative speed with which competitors can
develop their respective products, complete the clinical testing and regulatory
approval process and supply commercial quantities of their products to the
market. In addition to these factors, competition is expected to be based on
the effectiveness of blood substitute products and the scope of the intended
uses for which they are approved, the scope and enforceability of patent or
other proprietary rights, product price, product supply and marketing and sales
capability. The Company believes that its competitive position will be
significantly influenced by the timing of the clinical testing and regulatory
filings for PolyHeme, the Company's ability to expand its manufacturing
capability to permit commercial production of PolyHeme, if approved, and the
Company's ability to maintain and enforce its proprietary rights covering
PolyHeme and its manufacturing process.  See "Risk Factors - Competition."

                             GOVERNMENT REGULATION

The manufacture and distribution of PolyHeme and the operation of the
Company's manufacturing facilities will require the approval of United States
government authorities as well as those of foreign countries. In the United
States, the FDA regulates medical products, including the category known as
"biologicals" which includes PolyHeme. The Federal Food, Drug and Cosmetic Act
and the Public Health Service Act will govern the testing, manufacture, safety,
effectiveness, labeling, storage, record keeping, approval, advertising and
promotion of PolyHeme. In addition to FDA regulations, the Company is also
subject to other federal and state regulations, such as the Occupational Safety
and Health Act and the Environmental Protection Act. Product development and
approval within this regulatory framework requires a number of years and
involves the expenditure of substantial funds.


Northfield Laboratories Inc. (a company in the development stage)


<PAGE>   9



The steps required before a biological product may be sold commercially in the
United States include preclinical testing, the submission to the FDA of an
Investigational New Drug application, clinical trials in humans to establish
the safety and effectiveness of the product, the submission to the FDA of a
Biologic License Application ("BLA") relating to the product and the
manufacturing facilities to be used to produce the product for commercial sale,
and FDA approval of a BLA prior to any commercial sale or use of the product.

Preclinical tests include evaluation of product chemistry and studies to assess
the safety and effectiveness of the product and its formulation. The results of
the preclinical tests are submitted to the FDA as part of the Investigational
New Drug application. The goal of clinical testing is the demonstration in
adequate and well-controlled studies of substantial evidence of the safety and
effectiveness of the product in the setting of its intended use. The results of
preclinical and clinical testing are submitted to the FDA from time to time
throughout the trial process. In addition, before approval for the commercial
sale of a product can be obtained, results of the preclinical and clinical
studies must be submitted to the FDA in the form of a BLA. The testing and
approval process requires substantial time and effort and there can be no
assurance that any approval will be granted on a timely basis, if at all. The
approval process is affected by a number of  factors, including the severity of
the condition being treated, the availability of alternative treatments and the
risks and benefits demonstrated in clinical trials. Additional preclinical
studies or clinical trials may be requested during the FDA review process and
may delay product approval. After FDA approval for its initial indications,
further clinical trials may be necessary to gain approval for the use of a      
product for additional indications. The FDA may also require post-marketing
testing, which can involve significant expense, to monitor for adverse effects.

Among the conditions for BLA approval is the requirement that the prospective
manufacturer's quality controls and manufacturing procedures conform to FDA
requirements. In addition, domestic manufacturing facilities are subject to
biennial FDA inspections and foreign manufacturing facilities are subject to
periodic FDA inspections or inspections by the foreign regulatory authorities
with reciprocal inspection agreements with the FDA. Outside the United States,
the Company also is subject to foreign regulatory requirements governing
clinical trials and marketing approval for medical products. The requirements
governing the conduct of clinical trials, product licensing, pricing and
reimbursement vary widely from country to country.

The Company's regulatory strategy is to pursue clinical testing and FDA
approval of PolyHeme in the United States.  The Company intends to arrange for
testing and seek regulatory approval of PolyHeme outside the United States
through licensing or other arrangements with other foreign or domestic
companies. See "Risk Factors - Government Regulation and Uncertainty of Product
Approvals."

                          PATENTS AND PROPERTY RIGHTS

The Company owns four United States patents relating to PolyHeme, its uses and
certain of the Company's manufacturing processes. The Company has obtained
counterpart patents and has additional patents applications pending in Canada,
Israel, and various European Union countries. The Company's United States
patents expire in 2006. The Company has a policy of seeking patents covering
the important techniques, processes and applications developed from its
research and all modifications and improvements thereto. The Company also
relies upon trade secrets, know-how, continuing technological innovations and
licensing opportunities to develop and maintain its competitive position. The
Company will continue to seek appropriate protection for its proprietary
technology.

There can be no assurance that the Company's patents or other proprietary
rights will be determined to be valid or enforceable if challenged in court or
administrative proceedings or that the Company will not become involved in
disputes with respect to the patents or proprietary rights of third parties. An
adverse outcome from such proceedings could subject the Company to significant
liabilities to third parties, require disputed rights to be licensed from third
parties or require the Company to stop using such technology, any of which
would result in a material adverse effect on the Company's results of
operations. See "Risk Factors Uncertainty of Patents and Protection of
Proprietary Technology."

                            RESEARCH AND DEVELOPMENT

Since 1991, the principal focus of Northfield's research and development effort
has been the support of the clinical trials necessary for regulatory approval
of PolyHeme. The Company has also contracted for the preliminary engineering
necessary to assess the production of PolyHeme in commercial quantites.

In fiscal 1998, 1997 and 1996, the Company's research and development expenses
totaled $6,675,000, $5,188,000 and $5,223,000, respectively. The Company
anticipates that these expenses will increase as the Company funds the further
clinical testing of PolyHeme and prepares for its anticipated production in
commercial quantities.

                                HUMAN RESOURCES

As of May 31, 1998, the Company had 43 employees, of  whom 35 were involved in
research and development and eight were responsible for financial and other
administrative matters. The Company also had consulting arrangements with five
individuals as of such date. None of the Company's employees are represented by
labor unions, and the Company is not aware of any organizational efforts on
behalf of any labor unions involving the Company's employees. The Company
considers its relations with its employees to be excellent.

                                  RISK FACTORS


In addition to the other information contained in this document, the following
risk factors should be considered carefully in evaluating the Company and its
business.


                       NEED FOR EXTENSIVE CLINICAL TRIALS


The results of the Company's clinical trials are not sufficient at present to
demonstrate adequately the safety and effectiveness of PolyHeme in order to
file a BLA with the FDA. Although more than 100 individuals have participated
in clinical trials with PolyHeme, the Company will be required by the FDA to
conduct substantial additional trials, which are likely to be expensive and
time-consuming, before PolyHeme can be approved for commercial sale. The timing
of the FDA review process is uncertain. There can be no assurance that the
Company will be able to complete its clinical trials successfully or even
obtain FDA approval of PolyHeme, or that FDA approval, if obtained, will not
include limitations on the indicated uses for which PolyHeme may be marketed.
The Company's business, financial condition and results of operations are
critically dependent on receiving FDA approval of PolyHeme. A significant delay
in the Company's clinical trials or a failure to achieve FDA approval of
commercial sales of PolyHeme would have a material adverse effect on the
Company and could result in the cessation of the Company's business. The
Company or the FDA may in the future suspend clinical trials at any time if it
is believed that the subjects participating in such trials are being exposed to
unacceptable health risks.

                      GOVERNMENT REGULATION AND UNCERTAINTY
                              OF PRODUCT APPROVALS

The Company's research, development, testing, manufacturing, marketing and
distribution of PolyHeme are, and will continue to be, subject to extensive
regulation, monitoring and approval by the FDA and its foreign counterparts. The
regulatory approval process to establish the safety and effectiveness of
PolyHeme and the safety and reliability of the Company's manufacturing process
has already consumed several years and considerable expenditures. The data
obtained from clinical trials are susceptible to varying interpretations which
could delay, limit or prevent FDA regulatory approval. The lack of established
criteria for evaluating the effectiveness of blood substitute products could
also delay or prevent FDA regulatory approval. In addition, delay or rejection
could be caused by changes in FDA policies and regulations. Similar delays or
rejections may also be encountered in foreign countries. There can be no
assurance that, even after extensive clinical trials, regulatory approval will
ever be obtained for PolyHeme. Under new FDA guidelines, the FDA may comment
upon the acceptability of a BLA following its submission. There can be no
assurance that the FDA will accept the Company's BLA or, if the Company's BLA is
deemed acceptable, that PolyHeme will ultimately be approved for manufacture and
sale based on the Company's BLA. Moreover, if regulatory approval of PolyHeme is
granted, such approval may include limitations on the indicated uses for which
PolyHeme may be marketed. Further, even if such regulatory approval is obtained,
the Company does not presently have manufacturing facilities sufficient to
produce commercial quantities of PolyHeme. In order to seek FDA approval of the
sale of PolyHeme produced at its first commercial manufacturing facility, the
Company may be required to conduct a portion of its clinical trials with product
manufactured at that facility. Discovery of previously unknown problems with
PolyHeme or unanticipated problems with the Company's manufacturing facilities,
even after FDA approval of PolyHeme for commercial sale, may result in the
imposition of significant restrictions, including withdrawal of PolyHeme from
the market. Additional laws and regulations may also be enacted which could
prevent or delay regulatory approval of PolyHeme, including laws or regulations
relating to the price or cost-effectiveness of medical products. Any delay or
failure to achieve regulatory approval of commercial sales of PolyHeme is likely
to have a material adverse effect on the Company's financial condition.

                           EARLY STAGE OF DEVELOPMENT

The Company was founded in 1985 and is a development stage company. Since 1985,
the Company has been engaged primarily in the development and clinical testing
of PolyHeme. No revenues have been generated to date from commercial sales of
PolyHeme. The Company's revenues to date have consisted solely of license fees
and interest income. There can be no assurance that the Company's clinical
testing will be successful, that regulatory approval of PolyHeme will be
obtained, that the Company will be able to manufacture PolyHeme at an acceptable
cost and in appropriate quantities or that it will be able to successfully
market and sell PolyHeme. There can also be no assurance that the Company will
not encounter unexpected difficulties which will have a material adverse effect
on the Company, its operations or its properties.

                 RELIANCE ON SINGLE PRODUCT: TECHNOLOGICAL RISK


The Company's operations have to date consisted primarily of the development and
clinical testing of PolyHeme. The Company does not expect to realize product
revenues unless it successfully develops and achieves commercial introduction of
PolyHeme. The Company expects that such revenues, if any, will be derived solely
from sales of PolyHeme. The Company also expects the use of PolyHeme to be
limited primarily to the acute blood loss segment of the transfusion market. The
biomedical field has undergone rapid and significant technological changes.
Technological developments may result in PolyHeme becoming obsolete or
non-competitive before the Company is able to recover any portion of the
research and development and other expenses it has incurred to develop and
clinically test PolyHeme. Any such occurrence would have a material adverse
effect on the Company and its operations.







<PAGE>   12



                           MANUFACTURING UNCERTAINTIES

The Company intends to build a commercial-scale manufacturing facility
significantly larger than that currently being used to produce PolyHeme for the
Company's clinical testing. Northfield has no experience in commercial-scale
manufacturing, and there can be no assurance that Northfield can achieve
commercial-scale manufacturing capacity. There can also be no assurance that the
Company will not incur substantial cost overruns and delays compared to existing
estimates in building and equipping a commercial-scale manufacturing facility.
Moreover, in order to seek FDA approval of the sale of PolyHeme produced at its
first commercial manufacturing facility, the Company may be required to conduct
a portion of its clinical trials with product manufactured at that facility.
Accordingly, a delay in achieving scale-up of manufacturing capabilities will
have a material adverse effects on the completion of the Company's clinical
trials and therefore on the commercial manufacture and sale of PolyHeme.
Additionally, the manufacture of PolyHeme will be subject to extensive
government regulation. Among the conditions for marketing approval is that the
Company's quality control and manufacturing procedures conform to the FDA's good
manufacturing practice regulations. There can be no assurance that the Company
will be able to obtain the necessary regulatory clearances or approvals to
manufacture PolyHeme on a timely basis or at all.


                    LIMITATION OF SUPPLY OF STARTING MATERIAL


Northfield currently purchases donated blood from the American Red Cross and
Blood Centers of America for use as the starting material for PolyHeme. In 1996,
the Company entered into an agreement with hemerica, Inc., a subsidiary of Blood
Centers of America, under which hemerica would supply Northfield with 82,500
units per year of packed red cells, the source material for PolyHeme, over a
three year period. The Company has plans to enter long-term supply arrangements
with other blood collectors. There can be no assurance that the Company will be
able to enter into satisfactory long-term arrangements with blood bank
operators, that the price the Company may be required to pay for starting
material will permit the Company to price PolyHeme competitively or that the
Company will be able to obtain an adequate supply of starting material.
Additional demand for blood may arise from competing blood substitute products,
some of which are derived from human blood, thereby limiting the Company's
available supply of starting material.



                                   COMPETITION


If approved for commercial sale, PolyHeme will compete directly with established
therapies for acute blood loss and may compete with other technologies currently
under development. There can be no assurance that PolyHeme will have advantages
which will be significant enough to cause medical professionals to adopt it
rather than to continue to use established therapies or to adopt other new
technologies or products. There can also be no assurance that the cost of
PolyHeme will be competitive with the cost of established therapies or other new
technologies or products. The development of blood substitute products is a
rapidly evolving field. Competition is intense and expected to increase. Several
companies have developed or are in the process of developing technologies which
are, or in the future may be, the basis for products which will compete with
PolyHeme. Certain of these companies are pursuing different approaches or means
of accomplishing the therapeutic effects sought to be achieved through the use
of PolyHeme. Many of these companies have substantially greater financial
resources, larger research and development staffs, more extensive facilities and
more experience than Northfield in testing, manufacturing, marketing and
distributing medical products. There can be no assurance that one or more other
companies will not succeed in developing technologies or products which will
become available for commercial use prior to PolyHeme, which will be more
effective or less costly than PolyHeme or which would otherwise render PolyHeme
obsolete or non-competitive.

                    ABSENCE OF SALES AND MARKETING EXPERIENCE

If approved for commercial sale, the Company intends to market PolyHeme in the
United States using its own sales force. The Company has no experience in the
sale or marketing of medical products. The Company's ability to implement its
sales and marketing strategy for the United States will depend on its ability to
recruit, train and retain a






Northfield Laboratories Inc. (a company in the development stage)


<PAGE>   13



marketing staff and sales force with sufficient technical expertise. There can
be no assurance that the Company will be able to establish an effective
marketing staff and sales force, that the cost of establishing such a marketing
staff and sales force will not exceed revenues from the sale of PolyHeme or that
the Company's marketing and sales efforts will be successful.

       HISTORY OF LOSSES; UNCERTAINTY OF FUTURE PROFITABILITY OR FUNDING

From its inception to May 31, 1998, the Company had incurred net losses totaling
$60,740,000. The Company will require substantial additional expenditures to
complete clinical trials, to establish commercial scale manufacturing processes
and facilities, and to establish marketing, sales and administrative
capabilities. These expenditures are expected to result in substantial losses
for at least the next several years. The expense and the time required to
realize any product revenues or profitability are highly uncertain. There can be
no assurance that the Company will be able to achieve product revenues or
profitability on a sustained basis or at all. The Company may require
substantial additional funds to achieve commercial production of PolyHeme. The
Company's future capital requirements will depend on many factors, including the
scope and results of clinical trials, the timing and outcome of regulatory
reviews, administrative and legal expenses, the status of competitive products,
the establishment of manufacturing capacity and the establishment of
collaborative relationships. There can be no assurance that such additional
funding will be available to the Company or, if available, that such funding can
be obtained on terms and conditions the Company will deem acceptable. Any such
additional funding may result in significant dilution to then existing
stockholders.


                        UNCERTAINTY OF MARKET ACCEPTANCE

Northfield anticipates that the market price for PolyHeme, if FDA approval is
received, will exceed the cost of transfused blood. Competitors may also develop
new technologies or products which are more effective or less costly than
PolyHeme. There can be no assurance that the price of PolyHeme, considered in
relation to PolyHeme's expected benefits, will be perceived by health care
providers and third party payors as cost-effective, or that the price of
PolyHeme will be competitive with transfused blood or with other new
technologies or products. The Company's results of operations may be adversely
affected if the price of PolyHeme is not considered cost-effective by health
care providers or third party payors of if PolyHeme does not otherwise receive
market acceptance.

         UNCERTAINTY OF PATENTS AND PROTECTION OF PROPRIETARY TECHNOLOGY

The Company's ability to compete effectively with other companies will depend,
in part, on its ability to protect and maintain the proprietary nature of its
technology. There can be no assurance as to the degree of protection offered by
the patents owned by the Company, or as to the likelihood that additional
patents in the United States, and certain other countries will be issued based
upon pending patent applications. Patent applications in the United States are
maintained in secrecy until patents are issued. The Company cannot be certain
that it was the first creator of the inventors covered by its patents or pending
patent applications or that it was the first to file patent applications for
such inventions. The high costs of enforcing patent and other proprietary rights
may also limit the degree of protection afforded the Company. The Company also
relies on unpatented proprietary technology, and there can be no assurance that
others may not independently develop thesame or similar technology or otherwise
obtain access to the Company's proprietary technology. There can be no assurance
that the Company's patents or other proprietary rights will be determined to be
valid or enforceable if challenged in court or administrative proceedings or
that the Company will not become involved in disputes with respect to the
patents or proprietary rights of third parties. An adverse outcome from such
proceedings could subject the Company to significant liabilities to third
parties, require disputed rights to be licensed from third parties or require
the Company to stop using such technology, any of which would result in a
material adverse effect on the Company's results of operations.

                                   PART II
                              ITEM 2. PROPERTIES

Northfield currently leases a 21,000 square foot pilot manufacturing facility
located in Mt. Prospect, Illinois, and maintains its principal executive offices
in Evanston, Illinois. The Company has renewed the leases for its manufacturing
facility and executive offices through June 2003 and February 2006,
respectively. The terms of the renewed leased are substantially the same as the
original leases for these facilities. Rent expense for the Company's 1998 fiscal
year was $444,330. The Company believes its present manufacturing facility is
capable of producing sufficient quantities of PolyHeme for all of the Company's
clinical trials in the United States and Europe.

The Company has acquired a parcel of undeveloped land in the Chicago
metropolitan area for development as the Company's initial commercial-scale
manufacturing facility. The initial engineering design studies for the facility,
which is anticipated to have a production capacity of approximately 300,000
units of PolyHeme per year, have been completed. Northfield expects that the
cost of constructing the facility, including land acquisition costs, will be
approximately $45 million. Northfield does not expect to commence construction
of its initial commercial-scale manufacturing facility until approximately 12-18
months prior to the estimated date of FDA approval of PolyHeme.

                            ITEM 3. LEGAL PROCEEDINGS

As of May 31, 1998, the Company was not a party to any material pending legal
proceedings.

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

Since its incorporation in 1985, Northfield has devoted substantially all of its
efforts and resources to the research, development and clinical testing of
PolyHeme. Northfield has incurred operating losses during each year of its
operations since inception and expects to incur substantial additional operating
losses for the next several years. From its inception to May 31, 1998,
Northfield incurred net operating losses totaling $60,740,000.

The Company's success will depend on several factors, including its ability to
obtain FDA regulatory approval of PolyHeme and the Company's manufacturing
facilities, obtain sufficient quantities of blood to manufacture PolyHeme in
commercial quantities, manufacture and distribute PolyHeme in a cost-effective
manner, and enforce its patent positions. The Company has experienced
significant delays in the development and clinical testing of PolyHeme. There
can be no assurance that the Company will be able to achieve these goals or that
it will be able to realize product revenues or profitability on a sustained
basis or at all.

The Company anticipates that research and development expenses will increase
during the foreseeable future. These expected increases are attributable to
anticipated future clinical trials for domestic and international markets,
monitoring and reporting the results of such trials and continuing process
development associated with improving the Company's manufacturing capacity to
permit commercial-scale production of PolyHeme. The Company expects that general
and administrative expenses will increase over the foreseeable future due to
increased expenses relating to the expansion of the Company's organization in
support of commercial operations.


                              RESULTS OF OPERATIONS

The Company reported no revenues for the fiscal years ended May 31, 1998, 1997
or 1996. From its inception through May 31, 1998, the Company has reported total
revenues of $3,000,000, all of which were derived from licensing fees.

                               OPERATING EXPENSES

Operating expenses for the fiscal year ended May 31, 1998, 1997 and 1996 totaled
$9,014,000, $7,505,000 and $7,732,000, respectively. On a percentage basis,
fiscal 1998 operating expenses exceeded fiscal 1997 expenses by 20.1%, while
fiscal 1997 operating expenses were 2.9% less than those incurred in fiscal
1996.

For the year ended May 31, 1998, research and development expenses totaled
$6,675,000, representing an increase of $1,487,00, or 28.7%, from the year ended
May 31, 1997. The year over year difference is due to increased expenses related
to the Company's Phase III clinical trials, validation services related to the
Company's existing prototype production facility and preparatory and analysis
work for the Company's planned commercial manufacturing facility.

 Research and development expenses for fiscal 1997 totaled $5,188,000, compared
to research and development expenses in fiscal 1996 of $5,223,000. This overall
decrease was the result of a decrease in depreciation expense as the Company's
prototype manufacturing facility approached the end of its depreciable life for
accounting purposes.

The Company anticipates that research and development expenses will increase
significantly for the foreseeable future. Additional costs are being planned for
multi-center clinical trials, third-party clinical monitoring, biostatistical
analysis and report preparation.

General and administrative expenses for the year ended May 31, 1998 totaled
$2,338,000, representing a $21,000, or 0.9%, increase from the $2,317,000
reported for the prior fiscal year. General and administrative spending remained
consistent with the prior fiscal year as the Company was able to effectively
control general and administrative costs while increasing the level of research
and development activity.

General and administrative expenses in fiscal 1997 totaled $2,317,000, which was
a decline of $192,000, or 7.6%, from the $2,509,000 in general and
administrative expenses reported in fiscal 1996. Expense reductions were
experienced in legal, public relations and state filing fees from those
experienced in fiscal 1996.

                                 INTEREST INCOME


Interest income for the year ended May 31, 1998 totaled $3,130,000, or a
$129,000 decrease from the comparable prior year period. Declining available
investment balances and fluctuating interest rates combined for the 4.0%
reduction in interest income.

Interest income for fiscal 1997 totaled $3,259,000, or a $306,000 increase from
the $2,953,000 of interest income reported in fiscal 1996. The Company had
higher available cash balances in fiscal 1997 and consequently earner more
interest income on a year over year basis.

Without an additional inflow of capital, interest income is expected to decline
for the foreseeable future as the cost of expanded clinical trials and
investments related to a commercial facility will lower available investment
balances.

                                    NET LOSS

For the year ended May 31, 1998, Northfield reported a net loss of $5,883,000,
or $.42 per basic share, compared to a prior year period net loss of $4,246,000,
or $.30 per basic share. Higher research expenses for expanded multi-center
clinical trials, increased costs associated with validation procedures for the
Company's prototype manufacturing process and lower interest income combined to
cause the reported net loss and per share net loss to increase.

Fiscal 1997 losses of $4,246,000, or $30 per basic share, compared favorably to
the fiscal 1996 loss of $4,779,000, or $.37 per basic share. The reduction in
the dollar loss of $533,000 reflected lower depreciation charges in fiscal 1997
on the Company's prototype manufacturing facility. Fiscal 1997 results also
reflected the inclusion of an additional 1,112,000 shares in the earnings (loss)
per basic share calculation.

                         LIQUIDITY AND CAPITAL RESOURCES

From its inception through May 31, 1998, the Company has used cash for operating
activities and for the purchase of property, equipment and engineering services
in the amount of $59,311,000. For the year ended May 31, 1998, these cash
expenditures totaled $6,826,000. The fiscal 1998 net cash outlay was greater
than the fiscal 1997 expenditure of $4,280,000 due primarily to a land purchase
for use as a manufacturing site and the Company's expanded clinical trials.

The Company has financed its research and development and other activities to
date primarily through the public and private sale of its equity securities and,
to a more limited extent, through the license of product rights. As of May 31,
1998, the Company had cash and marketable securities totaling $53,505,000.

The company believes its existing capital resources will be adequate to satisfy
its operating capital requirements and maintain its existing pilot manufacturing
plant and office facilities for approximately the next 36-48 months. Thereafter,
the Company is likely to require substantial addition capital to continue its
operations. If the company uses its own resources to fund the construction of a
commercial-scale manufacturing facility, which is estimated to cost
approximately $45 million, it will significantly accelerate the Company's need
to raise additional capital.

The Company may enter into collaborative arrangements with strategic partners
which could provide the Company with additional funding or absorb expenses
otherwise payable by the Company. The Company has engaged in discussions with a
number of potential strategic partners, though these discussions are at
preliminary stages and there can be no assurance that any such arrangement will
be consummated.

The Company's capital requirements may vary materially from those now
anticipated because of the results of the clinical testing of PolyHeme, the
establishment of relationships with strategic partners, changes in the scale,
timing or cost of the Company's commercial manufacturing facility, competitive
and technological advances, the FDA regulatory process, changes in the Company's
marketing and distribution strategy and other factors.






<PAGE>   18



                              YEAR 2000 COMPLIANCE

The Company has reviewed its internal computer applications and has consulted
with its vendors who provide software services. The Company believes it is
substantially year 2000 compliant and that any required changes in coding will
be handled in a manner non-disruptive to its business and at a minimal cost.

Northfield is dependent in its operations on a number of suppliers whose
individual status in achieving a year 2000 conversion is not known at this time.
In the event that Northfield or any of Northfield's significant suppliers
experience disruption due to the year 2000 issue, the Company's operations could
be adversely affected.

<PAGE>   27
                        NOTES TO FINANCIAL STATEMENTS

May 31, 1998 and 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF OPERATIONS IN THE DEVELOPMENT STAGE
Northfield Laboratories Inc. (the Company), a Delaware corporation, was
incorporated on June 19, 1985 to research, develop, test, manufacture, market,
and distribute a hemoglobin-based blood substitute product. The Company is
continuing its research and development activities.
 
BASIS OF PRESENTATION
The financial statements have been prepared in accordance with the provisions of
Statement of Financial Accounting Standards (SFAS) No. 7, Accounting and
Reporting by Development Stage Enterprises, which requires development stage
companies to employ the same generally accepted accounting principles as
operating companies.
 
SHORT-TERM MARKETABLE SECURITIES
Short-term marketable securities consist of government securities, corporate
notes, and certificates of deposit with original maturities of less than one
year. The Company classifies its investment securities as held-to-maturity.
Held-to-maturity securities are those securities which the Company has the
ability and intent to hold until maturity. Held-to-maturity securities are
recorded at amortized cost, adjusted for the amortization or accretion of
premiums or discounts. Premiums and discounts are amortized or accreted over the
life of the related security as an adjustment to yield using the straight-line
method, which approximates the effective interest method. Interest income is
recognized when earned.
 
PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment are recorded at cost and are depreciated using the
straight-line method over the estimated useful lives of the respective assets,
generally five to seven years. Leasehold improvements are amortized using the
straight-line method over the lesser of the life of the asset or the term of the
lease, generally eight to ten years.
 
CAPITALIZED ENGINEERING COSTS
Capitalized engineering costs include design and other initial engineering
studies relating to a commercial scale facility. During fiscal 1998 and 1997,
the Company capitalized $18,128 and $100,717, respectively, of such engineering
costs. Upon completion of construction, these costs will be amortized over the
estimated useful life of the facility. For the years ended May 31, 1998 and
1997, no amortization of the capitalized costs was recorded.
 
COMPUTATION OF NET LOSS PER SHARE
During fiscal 1998, the Company adopted SFAS No. 128, Earnings Per Share, which
established new methods for computing and presenting earnings per share (EPS)
and replaced the presentation of primary and fully-diluted EPS with basic
(Basic) and diluted EPS. Basic earnings per share is based on the weighted
average number of shares outstanding and excludes the dilutive effect of
unexercised common equivalent shares. Diluted earnings per share is based on the
weighted average number of shares outstanding and includes the dilutive effect
of unexercised common equivalent shares. Because the Company reported a net loss
for the years ended May 31, 1998, 1997 and 1996 and the cumulative period from
June 19, 1985 (inception) through May 31, 1998, per share amounts have been
presented under the Basic method only.
     Had the Company reported net earnings for the years ended May 31, 1998,
1997 and 1996 and the cumulative period from June 19, 1985 (inception) through
May 31, 1998, the weighted average number of shares outstanding would have been
diluted by the

following common equivalent securities (not assuming the effects of applying the
treasury stock method):

USE OF ESTIMATES
Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from those estimates.
 
FINANCIAL INSTRUMENTS
The fair values of financial instruments, which consist of cash, marketable
securities (note 9), accounts payable, accrued expenses, and accrued
compensation and benefits, were not materially different from their carrying
values at May 31, 1998 and 1997.
 
STOCK BASED COMPENSATION
On June 1, 1996, the Company adopted SFAS No. 123, Accounting for Stock-Based
Compensation, which permits entities to recognize as expense over the vesting
period the fair value of all stock-based awards on the date of grant.
Alternatively, SFAS No. 123 allows entities to continue to apply the provisions
of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued
to Employees, and provide pro forma net income and earnings per share
disclosures as if the fair-value-based method defined in SFAS No. 123 had been
applied. The Company has elected to continue to apply the provisions of APB
Opinion No. 25 and provide the pro forma disclosures required by SFAS No. 123.
 
LONG-LIVED ASSETS
On June 1, 1996, the Company adopted SFAS No. 121, Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, under which
the Company has reviewed long-lived assets and certain intangible assets and
determined that their carrying values as of May 31, 1998 are recoverable in
future periods.
 
(2) PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment, at cost, less accumulated depreciation and
amortization, is summarized as follows as of May 31, 1998 and 1997:

(4) INCOME TAXES
As a result of losses incurred to date, the Company has not provided for income
taxes. As of May 31, 1998, the Company had net operating loss carryforwards for
income tax purposes of approximately $62,100,000, which are available to offset
future taxable income, if any, through 2001 to 2013. Deferred tax assets
primarily resulted from net operating loss carryforwards and differences in the
recognition of research and development, compensatory stock options, and
depreciation expenses and the tax benefit from the exercise of stock




<PAGE>   30
 
options. Additionally, the Company had approximately $1,600,000 of research and
experimentation tax credits and investment tax credits available to reduce
future income taxes through 2013.
     Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards.
     The net deferred tax assets as of May 31, 1998 and 1997 are summarized as
follows:

(5) STOCK OPTION PLAN
The Company's Restated Nonqualified Stock Option Plan (the "Employee Stock
Option Plan") lapsed on September 30, 1996. Following termination of the Plan,
all options outstanding prior to plan termination may be exercised in accordance
with their terms. As of May 31, 1998, options to purchase a total of 145,500
shares of the Company's Common Stock at prices between $6.38 and $15.19 per
share were outstanding under the Employee Stock Option Plan. These options
expire between 1999 and 2004, ten years after the date of grant.
     With an effective date of October 1, 1996, the Company established the
Northfield Laboratories Inc. 1996 Stock Option Plan (the 1996 Option Plan). This
plan provides for the granting of stock options to the Company's directors,
officers, key employees and consultants. Stock options to purchase a total of
500,000 shares of common stock are available under the 1996 Option Plan. During
the year ended May 31, 1998, the Company granted 100,000 options to purchase
shares of common stock at prices between $9.56 and $13.38 per share, which was
equal to the fair market value of a share of common stock at the date of grant.
These options expire in 2007 and 2008, ten years after the date of grant. During
the year ended May 31, 1997, the Company granted 195,000 options to purchase
shares of common stock at prices between $10.81 and $11.44 per share, which was
equal to the fair market value of a share of common stock at the date of grant.
These options expire in 2006 and 2007, ten years after the date of grant.
     Compensation expense (benefit) in the amount of $1,284, $2,569 and
$(62,726) was recorded for those compensatory options vesting during the years
ended May 31, 1998, 1997 and 1996, respectively. Compensation expense represents
the amortization over the vesting period of the total deferred compensation
attributable to the difference between the fair market value of the options at
the date of grant and the exercise price.
     In September 1994, the Company adopted the Nonqualified Stock Option Plan
for Outside Directors (Directors Plan) which provides for the granting of
nonqualified stock options to directors of the Company who are neither employees
of nor consultants to the Company and who were not directors of the Company
prior to June 1, 1994. Stock options to purchase a total of 200,000 shares of
common stock are available under the Directors Plan. During the year ended May
31, 1998, the Company granted 15,000 options to purchase shares of common stock
at a price of $13.38 per share, which was equal to the fair market value of a
share of common stock at the date of grant. These options expire in 2008, ten
years after the date of grant.


Northfield Laboratories Inc. (a company in the development stage)
<PAGE>   31
 
     The Company applies the intrinsic value method of APB Opinion No. 25 and
related interpretations in accounting for options granted to directors, officers
and key employees under the plans. Accordingly, compensation cost is recorded on
the date of grant only if the current market price of the underlying stock
exceeds the exercise price. Had compensation cost for the Company's stock option
plans been determined consistent with SFAS No. 123, the Company's net loss and
net loss per share would have been the pro forma amounts indicated below:

     For purposes of calculating the compensation cost consistent with SFAS No.
123, the fair value of each option grant is estimated using the Black-Scholes
option-pricing model with the following weighted-average assumptions used for
grants in fiscal 1998 and 1997 (as noted above, no options were granted in
1996):

                           SECOND AMENDMENT TO LEASE


          This Second Amendment to Lease ("Second Amendment"), dated May 6, 1998
is between OTR, an Ohio general partnership acting as the duly authorized
nominee of the board of The State Teachers Retirement System of Ohio
("Lessor"), whose address is 275 East Board Street, Columbus, Ohio 43215, and
NORTHFIELD LABORATORIES INC., a Delaware corporation ("Lessee").


                                WITNESSETH: THAT


          A.   Whereas, Lessor and Lessee have entered into a certain Lease
dated June 8, 1989 and further amended November 24, 1992 (the First Amendment
To Lease), for the lease of certain premises located in the Property
("Property") known and described as 1200 Business Center Drive, Suite 200, 
Mt. Prospect, IL 60056.

          B.   Whereas, Lessee in accordance with Paragraph 3 of the First
Amendment To Lease dated November 24, 1992 desires to exercise it's Second
Option to Renew. (Second Renewal Option) Effective July 1, 1998 and for a
period of five (5) years upon the terms and conditions set forth below and in
the manner hereinafter set forth.

          NOW, THEREFORE, in consideration of the mutual promises, covenants
and conditions contained in this Agreement, the parties agree as follows:

          1.   Second Renewal Option Term  The term of the Second Renewal
Option will be for a period of five (5) years, commencing July 1, 1998 and
ending June 30, 2003 upon the same terms and conditions set forth in the Lease,
except as otherwise provided in this Second Amendment To Lease. Any reference
in the Lease to "Term" shall include this Second Renewal Option Term.

          2.   Base Rent

               (a)  The Annual Base Rent for first three years of the Term
                    (7-01-98 thru 6/30/01) shall be the sum of Three Hundred Two
                    Thousand Nine-Hundred Forty Dollars and No-Cents
                    ($302,940.00) payable monthly, in advance, in thirty-six
                    (36) equal installments of Eight-Thousand Four-Hundred
                    Fifteen Dollars and No-Cents ($8,415.00).

               (b)  The Annual Base Rent for the period (7/01/01 thru 6/30/03)
                    shall be the sum of Two-Hundred Fourteen Thousand
                    Two-Hundred Dollars and No-Cents ($214,200.00) payable
                    monthly, in advance, in twenty-four (24) equal installments
                    of Eight-Thousand Nine-Hundred and Twenty-Five dollars and
                    No-Cents ($8,925.00).

          3.   If the Second Amendment To Lease term commences on a date other
than the first day of a calendar month or ends on a date other than the last
day of a calendar month, the monthly rent for the first month of the Renewal
Term or the last month of the Extension Term, as the case may be, shall be
prorated based upon the ratio that the number of the days in the Renewal Term
within such month bears to the total number of days in such month.

     4.   Effective Date  This Second Amendment shall be effective as of July 1,
1998 and shall inure to the benefit of the parties's heirs, successors and
assigns.

     5.   Non-conflicting Lease Terms Ratified  Except as modified herein, the
terms, covenants and conditions of the Lease are ratified and confirmed and the
parties shall be bound by, and shall have the benefits of, all the terms,
covenants and conditions of the Lease.

     6.   Brokerage Commission  Except for any broker, agent or other person
named below, Landlord and Tenant represent and warrant each to the other that
each has dealt with no broker, agent or other person in connection with this
transaction and that no broker, agent or other person brought about this
transaction. Landlord hereby agrees to pay Insignia/ESG, Inc. ("Agent") a
leasing commission as set forth in that certain Management Agreement between
landlord and Agent, from which Agent has agreed to pay a "co-op" leasing
commission to Cushman & Wakefield of Illinois, Inc. ("Co-op Broker"). Tenant
agrees to indemnify and hold Landlord harmless from and against any claims by
any other broker, agent or other person (including, without limitation, Co-op
Broker) claiming a commission to other form of compensation by virtue of
having dealt with Tenant with regard to this leasing transaction. The
provisions of this Paragraph 6 shall survive the termination of the Lease as
amended by this Second Amendment.

     7.   Second Amendment Controls  If any terms, covenants or conditions of
this Second Amendment conflict with the terms, covenants and conditions of the
Lease, then the terms and conditions of this Second Amendment shall control.

          IN WITNESS WHEREFORE, the parties to this Second Amendment to Lease
Agreement have extended the same on the day and year written above.
