           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This Quarterly Report contains forward-looking statements concerning, among
other things, our prospects, clinical and regulatory developments affecting our
potential product and our business strategies. These forward-looking statements
are identified by the use of such terms as "intends," "expects," "plans,"
"estimates," "anticipates," "forecasts," "should," "believes" and similar terms.

These forward-looking statements involve risks and uncertainties. Actual results
may differ materially from those predicted by the forward-looking statements
because of various factors and possible events, including those discussed under
"Risk Factors" in our Annual Report on Form 10-K filed with the Securities and
Exchange Commission and those matters discussed under "Legal Proceedings" in
this Quarterly Report. Because these forward-looking statements involve risks
and uncertainties, actual results may differ significantly from those predicted
in these forward-looking statements. You should not place undue weight on these
statements. These statements speak only as of the date of this document or, in
the case of any document incorporated by reference, the date of that document.

All subsequent written and oral forward-looking statements attributable to
Northfield or any person acting on our behalf are qualified by the cautionary
statements in this section and in our Annual Report. We will have no obligation
to revise these forward-looking statements.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors
Northfield Laboratories Inc.:

We have reviewed the balance sheet of Northfield Laboratories Inc. (a company in
the development stage) as of February 28, 2006, and the related statements of
operations for the three-month periods ended February 28, 2006 and 2005, and the
statements of operations and cash flows for the nine-month periods ended
February 28, 2006 and 2005, and for the period from June 19, 1985 (inception)
through February 28, 2006. We have also reviewed the statements of shareholders'
equity (deficit) for the nine-month period ended February 28, 2006 and for the
period from June 19, 1985 (inception) through February 28, 2006. These financial
statements are the responsibility of the Company's management.

We conducted our review in accordance with the standards of the Public Company
Accounting Oversight Board (United States). A review of interim financial
information consists principally of applying analytical procedures and making
inquiries of persons responsible for financial and accounting matters. It is
substantially less in scope than an audit conducted in accordance with the
standards of the Public Company Accounting Oversight Board (United States), the
objective of which is the expression of an opinion regarding the financial
statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the financial statements referred to above for them to be in
conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the balance sheet of
Northfield Laboratories Inc. as of May 31, 2005, and the related statements of
operations, shareholders' equity (deficit), and cash flows for the year then
ended and for the period from June 19, 1985 (inception) through May 31, 2005
(not presented herein); and in our report dated August 12, 2005, we expressed an
unqualified opinion on those financial statements. In our opinion, the
information set forth in the accompanying balance sheet as of May 31, 2005 and
in the accompanying statements of operations, cash flows and shareholders'
equity (deficit) is fairly stated, in all material respects, in relation to the
statements from which it has been derived.

                         NOTES TO FINANCIAL STATEMENTS
                               FEBRUARY 28, 2006
                                  (UNAUDITED)

(1)  BASIS OF PRESENTATION

The interim financial statements presented are unaudited but, in the opinion of
management, have been prepared in conformity with accounting principles
generally accepted in the United States of America applied on a basis consistent
with those of the annual financial statements. Such interim financial statements
reflect all adjustments (consisting of normal recurring accruals) necessary for
a fair presentation of the financial position, results of operations and cash
flows for the interim periods presented. The results of operations for the
interim periods presented are not necessarily indicative of the results to be
expected for the full fiscal years. The interim financial statements should be
read in connection with the audited financial statements for the year ended May
31, 2005.

(2)  USE OF ESTIMATES

Our management 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 accounting
principles generally accepted in the United States of America. Actual results
could differ from those estimates.

(3)  COMPUTATION OF NET LOSS PER SHARE

Basic earnings per share is based on the weighted average number of shares
outstanding and excludes the dilutive effect of unexercised common stock
equivalents. Diluted earnings per share is based on the weighted average number
of shares outstanding and includes the dilutive effect of unexercised common
stock equivalents. Because we reported net losses for all periods presented,
basic and diluted per share amounts are the same. As of February 28, 2006, we
have 1,758,375 options and 212,392 warrants that were excluded from the net loss
per share calculation because their inclusion would have been anti-dilutive.

(4)  STOCK OPTIONS

We account for our fixed plan stock options under the intrinsic value method of
accounting prescribed by Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees", and related interpretations in accounting for
options granted to directors, officers, and key employees under the plans. As
such, compensation expense is recorded on the date of grant and amortized over
the period of service only if the current market value of the underlying stock
exceeded the exercise price. No stock option based employee compensation cost is
reflected in net loss, as each option granted under these plans had an exercise
price equal to the market value of the underlying common stock on the date of
grant.

The following table illustrates the effect on net loss if we had applied the
fair value recognition provisions of Statement of Financial Accounting Standards
(SFAS) No. 123, "Accounting for Stock Based Compensation" to the measurement of
stock-based employee compensation,

including a straight-line recognition of compensation costs over the related
vesting periods for fixed awards:

(5)  RECENTLY ISSUED ACCOUNTING STANDARD

In December 2004, Statement of Financial Accounting Standards (SFAS) No. 123
(Revised 2004), "Share-Based Payment: an amendment of FASB Statements No. 123
and 95", was issued. This Statement amends SFAS No. 123, "Accounting for
Stock-Based Compensation", and requires companies to recognize in the income
statement the grant-date fair value of stock options and other equity-based
compensation issued to employees. The Statement is effective for public
companies with annual periods beginning after June 15, 2005. The Company will
adopt SFAS

<PAGE>

123(R) for the three-month period ending August 31, 2006. The Company will
assess the impact of the transition to this new accounting standard during the
upcoming months.

(6)  MARKETABLE SECURITIES

     The Company, at February 28, 2006, is invested in high grade commercial
paper. The Company has the intent and ability to hold these securities until
maturity and all securities have a maturity of less than one year.

     The fair market value of the Company's marketable securities was
$30,809,703 at February 28, 2006, which included gross unrealized holding losses
of $378. The fair market value of the Company's marketable securities was
$91,209,903 at May 31, 2005, which included gross unrealized holding losses of
$120,386. All of these marketable securities are scheduled to mature in less
than one year.

(7)  LEGAL PROCEEDINGS

     Subsequent to the end of the Company's fiscal third quarter, the Company
and its chief executive officer were named as defendants in purported class
action lawsuits pending before the federal District Court for the Northern
District of Illinois alleging various violations of the federal securities laws.
These lawsuits allege, among other matters, that the Company failed to
adequately disclose information regarding the results from a clinical trial of
its PolyHeme product in elective surgery that was conducted from 1998 to 2001.
Although the Company believes these lawsuits lack merit, the lawsuits are at an
early stage and it is not possible at this time to predict the outcome of any of
the matters or their potential effect, if any, on the Company or the clinical
development or future commercialization of its PolyHeme product.
<PAGE>

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
     OF OPERATIONS.

RECENT DEVELOPMENTS

     We are currently enrolling patients in a pivotal Phase III trial in which
our PolyHeme(R) hemoglobin-based oxygen-carrying resuscitative fluid is being
used for the first time in the U.S. to treat severely injured patients in
hemorrhagic shock before they reach the hospital. Under this protocol, treatment
with PolyHeme begins at the scene of the injury or in the ambulance and
continues during transport and the initial 12-hour post-injury period in the
hospital. Since blood is not presently carried in ambulances, the use of
PolyHeme in this setting has the potential to improve survival and address a
critical, unmet medical need.

     Twenty-seven of the 32 clinical sites that have received Institutional
Review Board, or IRB, approval to participate in our pivotal Phase III trial are
enrolling patients in the trial. Thirty-one of these sites have initiated
enrollment and the last is scheduled to open in April 2006. Three sites have
suspended enrollment of patients in order to review their participation in the
trial, and one site has suspended enrollment pending additional retraining. This
review follows recent media reports that have challenged certain aspects of the
design of our trial and the adequacy of the community consultation process
conducted by clinical sites in connection with the trial. A number of other
trial sites have conducted similar reviews and have already resumed their
enrollment of patients in our trial.

     Each of the sites participating in the trial is designated as a Level I
trauma center, indicating its capacity to treat the most severely injured trauma
patients. The trial has an expected enrollment of 720 patients.
<PAGE>

     As part of our trial protocol, an Independent Data Monitoring Committee, or
IDMC, is responsible for periodically evaluating the safety data from the trial
and making recommendations relating to the continuation or modification of the
trial protocol to minimize any identified risks to patients. The IDMC has
completed four separate evaluations after 60, 120, 250 and 500 patients were
enrolled in our trial and monitored for a 30-day follow up period. The IDMC has
stated that it observed no statistically significant trends or safety issues
that would warrant modification or other changes in our current trial protocol
or patient recruitment. Based on these observations, the IDMC has recommended
that our trial continue to completion without modification. We will not have
access to the trial data reviewed by the IDMC until the trial is completed and
the database has been cleaned and locked by our contract research organization.

     As of March 31, 2006, approximately 655 patients had been enrolled in our
pivotal Phase III trial. Our current goal is to complete the patient enrollment
phase in the second quarter of calendar year 2006. Our ability to achieve this
goal will depend, in part, on the number of clinical sites continuing to
participate in our trial and the ability of these sites to enroll patients at
the projected rates.

     The progress of our pivotal Phase III trial and the timing and outcome of
the Food and Drug Administration, or FDA, review process are subject to
significant risks and uncertainties, many of which are outside of our control.
We urge you to review the "Risk Factors" section in our most recent Annual
Report on Form 10-K filed with the Securities and Exchange Commission for a
discussion of certain of these risks and uncertainties.

     Since Northfield's incorporation in 1985, we have devoted substantially all
of our efforts and resources to the research, development and clinical testing
of our potential product, PolyHeme. We have incurred operating losses during
each year of our operations since inception and expect to incur substantial
additional operating losses for the next several years. From Northfield's
inception through February 28, 2006, we have incurred operating losses totaling
$163,806,000.

     We will be required to complete our pivotal Phase III trial and obtain FDA
regulatory approval before PolyHeme can be sold commercially. The FDA regulatory
process is subject to significant risks and uncertainties, and we therefore
cannot at this time reasonably estimate the timing of any future revenues from

<PAGE>

the commercial sale of PolyHeme. The costs incurred by Northfield to date and
during each period presented below in connection with our development of
PolyHeme are described in the Statements of Operations in our financial
statements.

     Our success will depend on several factors, including our ability to obtain
FDA regulatory approval of PolyHeme and our manufacturing facilities, obtain
sufficient quantities of human red blood cells to manufacture PolyHeme in
commercial quantities, manufacture and distribute PolyHeme in a cost-effective
manner, enforce our patent positions and raise sufficient capital to fund these
activities. We have experienced significant delays in the development and
clinical testing of PolyHeme. We cannot ensure that we will be able to achieve
these goals or that we will be able to realize product revenues or profitability
on a sustained basis or at all.

                              RESULTS OF OPERATIONS

     We reported no revenues for either of the three and nine-month periods
ended February 28, 2006 or 2005. From Northfield's inception through February
28, 2006, we have reported total revenues of $3,000,000, all of which were
derived from licensing fees.

                               OPERATING EXPENSES

     Operating expenses for our third fiscal quarter ended February 28, 2006
totaled $7,240,000, an increase of $2,111,000 from the $5,129,000 reported in
the third quarter of fiscal 2005. Measured on a percentage basis, third quarter
fiscal 2006 operating expenses exceeded third quarter fiscal 2005 expenses by
41.2%. As expected, significant increases in operating expenses were incurred to
conduct, expand, report and support our pivotal Phase III trial.

<PAGE>

     Research and development expenses during the third quarter of fiscal 2006
totaled $5,786,000, an increase of $1,968,000, or 51.5%, from the $3,818,000
reported in the third quarter of fiscal 2005. Our pivotal Phase III trial is
enrolling patients at 10 additional clinical sites compared to a year ago. Also
included in the current quarter research and development expenses was an
increased use of scientific and regulatory consultants to prepare for the
reporting of data from our trial to FDA.

     General and administrative expenses in the third quarter of fiscal 2006
totaled $1,454,000, which is an increase of $143,000, or 10.9%, from the
$1,311,000 of general and administrative expenses reported in the third quarter
of fiscal 2005. The increased expenses in the third quarter of fiscal 2006
compared to the third quarter of fiscal year 2005 were due to increased
professional service fees, compensation accruals, insurance costs, and state
taxes determined by our capital structure. We anticipate potentially significant
general and administrative expense increases for the remainder of the fiscal
year. No new general and administrative programs are currently planned, as
successfully completing our pivotal Phase III trial remains our primary focus.
However, we anticipate potentially significant general and administrative
expense increases for the remainder of the fiscal year due primarily to the
proceedings discussed below.

     Subsequent to the end of our fiscal third quarter, we received an informal
request from the staff of the Securities and Exchange Commission, or SEC, to
voluntarily provide certain information relating to the clinical development of
PolyHeme in elective surgery. We intend to cooperate with the SEC staff in
connection with its review of this information. We have also agreed to
voluntarily provide similar information to the staff of the Finance Committee of
the United States Senate. In addition, Northfield and our chief executive
officer were named as defendants in purported class action lawsuits alleging
violations of the federal securities laws relating to the disclosure of results
from a clinical trial of our PolyHeme product in elective surgery that was
conducted from 1998 to 2001. While we believe these lawsuits lack merit, each of
these matters is at an early stage and it is not possible at this time to
predict the outcome of any of the matters or their potential effect, if any, on
Northfield or the clinical development or future commercialization of our
PolyHeme product. See "Legal Proceedings." We anticipate significant future
increases in our general and administrative expenses resulting from professional
fees and expenses incurred in connection with these matters.

     For the nine-month period ended February 28, 2006, operating expenses of
$20,756,000 exceeded the operating expenses of $15,203,000 incurred in the
nine-month period ended February 28, 2005. The dollar increase was $5,553,000
and the percentage increase equaled 36.5%. The increases are primarily
attributed to the planning, preparation, execution, analysis and reporting of
our pivotal Phase III trial.

<PAGE>

     Research and development expenses for the nine-month period ended February
28, 2006 totaled $16,454,000, which represents a $4,420,000, or 36.7%, increase
from the comparable expenses incurred in the nine-month period ended February
28, 2005. During the current fiscal year, increased expense totaling $2,676,000
was reported for clinical site activities and the direct costs of trial
monitoring, analysis and reporting. During the current fiscal year, the
organization has expanded by 10 net hires contributing to increased compensation
and recruiting costs. Also this fiscal year we are conducting additional work in
multiple areas to refresh and update our database in preparation for filing a
license application with FDA.

     General and administrative expenses for the nine-month period ended
February 28, 2006 totaled $4,303,000, which is an increase of $1,133,000, or
35.7%, from the $3,170,000 of general and administrative expenses reported for
the nine-month period ended February 28, 2005. The increased expenses this
fiscal year are due to higher employment levels, increased compensation
accruals, higher professional services fees, primarily for legal and investor
relations, increased insurance costs and additional taxes payable based on our
increased market capitalization.

                                 INTEREST INCOME

     Interest income for the three-month period ended February 28, 2006 totaled
$845,000, an increase of $564,000 from the $281,000 in interest income reported
in the three-month period ended February 28, 2005. The increase in our interest
income is due to our improved cash position resulting from our successful equity
financing during February 2005 and higher short-term interest rates.

     Interest income for the nine-month period ended February 28, 2006 totaled
$2,312,000, an increase of $1,755,000 from the $557,000 in interest income
reported in the nine-month period ended February 28, 2005. The increase in cash
balances and increases in available short-term interest rates caused interest
income to increase. We continue to invest our funds only in high grade,
short-term instruments.

<PAGE>

                                    NET LOSS

     Our net loss for the three-month period ended February 28, 2006 totaled
$6,395,000, or $0.24 per share, compared to a net loss of $4,848,000, or $0.21
per share, for the three-month period ended February 28, 2005. In dollar terms,
the loss increased by $1,547,000 or 31.9%, primarily as a result of the
increased expenses relating to our pivotal Phase III trial.

     On a fiscal year to date basis, we reported a loss of $18,445,000, or $0.69
per share, compared to a prior year nine-month loss of $14,646,000, or $0.67 per
share. The increased net loss of $3,799,000, or 25.9%, was primarily the result
of increased expenses relating to our pivotal Phase III trial during the first
nine-months of the current fiscal year.

                         LIQUIDITY AND CAPITAL RESOURCES

     From Northfield's inception through February 28, 2006, we have used cash in
operating activities and for the purchase of property, plant, equipment and
engineering services in the amount of $160,874,000. For the nine-months ended
February 28, 2006 and February 28, 2005, these cash expenditures totaled
$19,240,000 and $14,540,000, respectively. The current fiscal year nine-month
increase in cash utilization is due primarily to increased expenses related to
our pivotal Phase III trial and professional service costs.

     We have financed our research and development and other activities to date
through the public and private sale of equity securities and, to a more limited
extent, through the license of product rights. As of February 28, 2006, we had
cash and marketable securities totaling $80,313,000. As previously reported, we
have been successful in securing a $1.4 million federal appropriation as part of
the Defense Appropriation Bill in 2005 and a $3.5 million federal appropriation
as part of the Fiscal 2006 Defense Appropriation Bill. As of February 28, 2006,
we have not yet received these funds.

<PAGE>

     We are currently utilizing our cash resources at a rate of approximately
$28 million per year. We expect, however, that the rate at which we utilize of
our cash resources will significantly increase over the next two years as we
launch our planned commercial plant expansion and further expand our business
organization for product launch.

     We anticipate that our expenditures for site monitoring and patient
enrollment in connection with our current Phase III clinical trial will be
completed in calendar 2006, while substantial additional costs will be incurred
during calendar 2006 to complete and submit a Biologics License Application for
PolyHeme with FDA. We also expect to incur additional expenses as we build
manufacturing, sales, marketing and distribution capabilities in support of the
commercialization of PolyHeme.

     Based on our current estimates, we believe our existing capital resources
will be sufficient to permit us to conduct our operations, including the planned
expansion of our manufacturing, sales, marketing and distribution capabilities,
for approximately 15 to 18 months. Excluding the projected costs relating to our
planned expansion activities, we believe our existing capital resources would be
sufficient to permit us to conduct our operations, including completion of our
current Phase III clinical trial and the preparation and submission of a BLA to
FDA, for approximately 30 to 36 months.

     We may in the future issue additional equity or debt securities or enter
into collaborative arrangements with strategic partners, which could provide us
with additional funding or absorb expenses we would otherwise be required to
pay. We are also pursuing potential sources of additional government funding.
Any one or a combination of these sources may be utilized to raise additional
capital. We believe our ability to raise additional capital or enter into a
collaborative arrangement with a strategic partner will depend primarily on the
results of our clinical trial, as well as general conditions in the business and
financial markets.

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

                          CRITICAL ACCOUNTING POLICIES

     The preparation of financial statements requires management to make
estimates and assumptions that affect amounts reported therein. We believe the
following critical accounting policy reflects our more significant judgments and
estimates used in the preparation of our financial statements.

                        NET DEFERRED TAX ASSETS VALUATION

     We record our net deferred tax assets in the amount that we expect to
realize based on projected future taxable income. In assessing the
appropriateness of our valuation, assumptions and estimates are required, such
as our ability to generate future taxable income. In the event we were to
determine that it was more likely than not we would be able to realize our
deferred tax assets in the future in excess of their carrying value, an
adjustment to recognize the deferred tax assets would increase income in the
period such determination was made. As of February 28, 2006, we have recorded a
100% percent valuation allowance against our net deferred tax assets.

                             CONTRACTUAL OBLIGATIONS

     The following table reflects a summary of our contractual cash obligations
as of February 28, 2006:

     at any time after February 14, 2009. If the lease is cancelled as of
     February 15, 2009 unamortized broker commissions of $17,470 would also be
     due.

(2)  Represents payments required to be made upon termination of employment

     payable upon the termination of the employment agreements for reasons other

     executive officer other than for good reason. Additional payments may be
     required under the employment agreements in connection with a termination
     of employment of the executive officers following a change in control of
     Northfield.

<PAGE>

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     We currently do not have any foreign currency exchange risk. We invest our
cash and cash equivalents in government securities, certificates of deposit and
money market funds. These investments are subject to interest rate risk.
However, due to the nature of our short-term investments, we believe that the
financial market risk exposure is not material. A one percentage point decrease
in the interest rate received on our cash and marketable securities of $80.3
million at February 28, 2006 would decrease interest income by $803,000 on an
annual basis.

ITEM 4. CONTROLS AND PROCEDURES.

     Based on their evaluation as of the end of the period covered by this
report, our Chief Executive Officer and Senior Vice President and Chief
Financial Officer have concluded that Northfield's disclosure controls and
procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities
Exchange Act of 1934, are effective to ensure that information required to be
disclosed by us in the reports that we file or submit under the Securities
Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the Securities and Exchange Commission's rules and forms.
There were no changes in our internal control over financial reporting that
occurred during our most recent fiscal quarter that have materially affected, or
are reasonably likely to materially affect, our internal control over financial
reporting.


<PAGE>
                           PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

     On March 13, 2006, Northfield received an informal request from the staff
of the SEC to voluntarily provide certain information relating to the clinical
development of PolyHeme in elective surgery. We intend to cooperate with the SEC
staff in connection with its review of this information. We have also agreed to
voluntarily provide similar information to the staff of the Finance Committee of
the United States Senate.

     In addition, Northfield and our chief executive officer have been named as
defendants in purported class action lawsuits pending before the federal
District Court for the Northern District of Illinois alleging various violations
of the federal securities laws. These lawsuits allege, among other matters, that
Northfield failed to adequately disclose information regarding the results from
a clinical trial of our PolyHeme product in elective surgery that was conducted
from 1998 to 2001.

     While we believe these lawsuits lack merit, each of these matters is at an
early stage and it is not possible at this time to predict the outcome of any of
the matters or their potential effect, if any, on Northfield or the clinical
development or future commercialization of our PolyHeme product.
