                  LIFE SCIENCES RESEARCH, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                             March 31, 2004 and 2003
                                    Unaudited


1.       THE COMPANY AND ITS OPERATIONS

Business

Life  Sciences  Research,  Inc.  ("LSR")  and  subsidiaries  (collectively,  the
"Company")  is a  global  contract  research  organization,  offering  worldwide
pre-clinical and non-clinical  testing for biological safety evaluation research
services to pharmaceutical,  biotechnology, agrochemical and industrial chemical
companies.  The Company  serves the rapidly  evolving  regulatory and commercial
requirements to perform safety evaluations on new  pharmaceutical  compounds and
chemical  compounds  contained  within the products that humans use, eat and are
otherwise  exposed  to.  In  addition,  the  Company  tests  the  effect of such
compounds on the  environment and also performs work on assessing the safety and
efficacy of veterinary products.

Organization

LSR was incorporated on July 19, 2001 as a Maryland  corporation.  It was formed
specifically  for the  purpose  of making a  recommended  all share  offer  (the
"Offer") for Life  Sciences  Research  Ltd (LSR Ltd)  formerly  Huntingdon  Life
Sciences  Group plc  ("Huntingdon").  The Offer was made on October 16, 2001 and
was  declared  unconditional  on January 10,  2002,  at which time LSR  acquired
approximately  89% of the outstanding  ordinary shares of Huntingdon in exchange
for  approximately 5.3 million shares of LSR Voting Common Stock. The subsequent
offer period expired on February 7, 2002, by which time approximately 92% of the
outstanding  ordinary  shares had been offered for  exchange.  LSR completed its
compulsory purchase under UK law of the remaining outstanding ordinary shares of
Huntingdon  on March 26,  2002 at which time  Huntingdon  became a wholly  owned
subsidiary of LSR, in exchange for a total of  approximately  5.9 million shares
of LSR Voting Common Stock (the "Exchange Offer").

Under accounting principles generally accepted in the United States ("US GAAP"),
the  Company  whose  stockholders  retain the  majority  interest  in a combined
business must be treated as the acquirer for accounting  purposes.  Accordingly,
the  Exchange  Offer is accounted  for as a reverse  acquisition  for  financial
reporting purposes.  The reverse acquisition is deemed a capital transaction and
the net assets of Huntingdon  (the  accounting  acquirer) are carried forward to
LSR (the legal acquirer and the reporting entity) at their carrying value before
the combination.  Although Huntingdon was deemed to be the acquiring corporation
for financial accounting and reporting purposes,  the legal status of LSR as the
surviving corporation does not change. The relevant acquisition process utilizes
the capital  structure of LSR and the assets and  liabilities  of Huntingdon are
recorded  at  historical  cost.  The equity of LSR is the  historical  equity of
Huntingdon, retroactively restated to reflect the number of shares issued in the
Exchange Offer.

LSR's executive office is based at the Princeton  Research Center in New Jersey,
US.

2.       BASIS OF PRESENTATION

The accompanying  unaudited condensed  consolidated financial statements reflect
all  adjustments  of a normal  recurring  nature,  which are,  in the opinion of
management,  necessary for a fair statement of the results of operations for the
interim periods presented.  The condensed  consolidated financial statements are
unaudited  and are subject to such  year-end  adjustments  as may be  considered
appropriate and should be read in conjunction  with the historical  consolidated
financial  statements  of LSR  years  ended  December  31,  2003,  2002 and 2001
included in LSR's Annual Report on Form 10-K for the fiscal year ended  December
31, 2003.  Operating results for the three-month period ended March 31, 2004 are
not  necessarily  indicative  of the results  that may be expected  for the year
ending December 31, 2004.

These  financial  statements  have been prepared in accordance  with US GAAP and
under the same accounting principles as the financial statements included in the
Annual Report on Form 10-K. Certain information and footnote disclosures related
thereto  normally  included in the financial  statements  prepared in accordance
with the US GAAP have been omitted in  accordance  with Rule 10-01 of Regulation
S-X.

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

1.      RESULTS OF OPERATIONS

a) Three months ended March 31, 2004 compared with three months ended
   March 31, 2003.

Net revenues for the three  months ended March 31, 2004 were $37.2  million,  an
increase of 16.7% on net  revenues of $31.9  million for the three  months ended
March 31, 2003.  Excluding the effect of exchange rate  movements,  the increase
was 4.7%. UK net revenues  increased by 18.9%;  at constant  exchange  rates the
increase  was 3.7%.  In the US, net revenues  increased  by 8.2%.  After an 8.5%
decline in net new orders in the year ended  December 31, 2003 compared to 2002,
net new orders for the three months ended March 31, 2004 were at a record level,
34% above the same period last year and 29% above Q4,  2003.  This growth in net
new orders,  which was  particularly  strong in  toxicology  and  pharmaceutical
chemistry , started to feed through into revenues in the quarter.

Cost of revenues for the three  months ended March 31, 2004 were $29.4  million,
an increase of 16.0 % on cost of revenue of $25.4  million for the three  months
ended March 31, 2003.  Excluding  the effects of exchange  rate  movements,  the
increase was 4.1%.  This increase was driven by the improvement in net revenues,
with direct material costs increasing by $1.0 million and labor by $1.5 million.
UK cost of revenues  increased by 17.6%; at constant exchange rates the increase
was 2.5%,  reflecting  the  increase  in volume,  mainly due to labor and direct
materials cost increases.  US cost of revenues  increased by 9.8%, a faster rate
than the  increase  in  revenues  as a result of  higher  direct  study  related
material costs.

Selling,  general  and  administrative  expenses  (SG&A)  rose by  12.3% to $5.5
million  for the three  months  ended  March 31,  2004 from $4.9  million in the
corresponding  period in 2003. Excluding the effects of exchange rate movements,
the increase was less than 1%. UK SG&A increased by 14.8% over the corresponding
period in 2003; at constant  exchange  rates UK SG&A  increased by 0.3%. US SG&A
also increased by 0.3%.

Net interest expense for the three months ended March 31, 2004 was $1.6 million,
which was $0.1 million lower than the net interest  expense for the three months
ended March 31, 2003.  Excluding the effects of exchange rate  movements,  there
was a net decrease of 19%, due to lower interest rates, lower borrowings,  and a
lower charge for warrants (as a result of the  repayment of related  party loans
in 2003).

Other income in the three months ended March 31, 2004 of $1.4 million relates to
the non-cash foreign exchange  remeasurement gain which arose on the Convertible
Capital  Bonds  denominated  in US  dollars  (the  functional  currency  of  the
financial subsidiary that holds the bonds in UK sterling), with the weakening of
the dollar  against  sterling.  In the three months ended March 31, 2003,  other
expense of $0.5 million related to the non-cash foreign  exchange  remeasurement
loss of $0.9  million  that  arose on the  Convertible  Capital  Bonds  with the
strengthening of the dollar against sterling, offset by $0.4 million gain on the
repurchase of Capital Bonds.

The income tax expense on income for the three  months  ended March 31, 2004 was
$0.7  million,  which was  primarily  a  non-cash  charge  due to the  company's
operating loss carry forwards. The income tax benefit for the three months ended
March 31, 2003 was $0.2 million.

The  overall  net  income for the three  months  ended  March 31,  2004 was $1.4
million  compared to a net loss of $0.4 million for the three months ended March
31,  2003.  The  improvement  in the net  income  of $1.8  million  is due to an
increase in the operating  income of $0.7 million,  lower  interest  charge $0.1
million and an increase in non-cash foreign exchange remeasurement gains of $2.3
million,  offset by an increase in the income tax expense of $0.9 million, and a
reduction in the gain on the repurchase of the Capital Bonds of $0.4 million.

Basic income per common  share was 12 cents,  compared to a loss of 3 cents last
year on the weighted  average  common shares  outstanding  of 12,039,874  (2003:
11,932,338).

2.      LIQUIDITY & CAPITAL RESOURCES

Bank Loan and Non-Bank Loans

On January 20, 2001,  the  Company's net non-bank  loan of  (pound)22.5  million
($41.1 million approximately),  was refinanced by Stephens' Group Inc. and other
parties.  The loan was  transferred  from  Stephens  Group Inc., to an unrelated
third party  effective  February 11, 2002.  It is now repayable on June 30, 2006
and  interest is payable  quarterly  at LIBOR plus  1.75%.  At the same time the
Company was required to take all  reasonable  steps to sell off some of its real
estate assets through  sale/leaseback  transactions  and/or  obtaining  mortgage
financing  secured by the Company's  real estate assets to discharge  this loan.
The loan is held by Life Sciences Research Ltd (LSR Ltd.), and is secured by the
guarantees  of the  Company's  wholly  owned  subsidiaries,  including  LSR Ltd,
Huntingdon   Life  Sciences  Ltd,  and   Huntingdon   Life  Sciences  Inc.,  and
collateralized by all the assets of these companies.

On October 9, 2001, on behalf of  Huntingdon,  LSR issued to Stephens Group Inc.
warrants  to  purchase  up to  704,425  shares of LSR Voting  Common  Stock at a
purchase price of $1.50 per share. The warrants were subsequently transferred to
an unrelated third party.  The LSR warrants are exercisable at any time and will
expire on October 9, 2011.  These warrants arose out of  negotiations  regarding
the  refinancing of the bank loan by the Stephens Group Inc. in January 2001. In
accordance  with APB Opinion No. 14,  Accounting for  Convertible  Debt and Debt
Issued with Stock  Purchase  Warrants  ("APB 14"), the warrants were recorded at
their pro rata fair values in relation to the  proceeds  received on the date of
issuance. As a result, the value of the warrants was $430,000.

Convertible Capital Bonds

The remainder of the Company's  long term  financing is provided by  Convertible
Capital  Bonds  repayable in September  2006.  At the time of the issue in 1991,
these bonds were for $50 million par and at March 31, 2004,  $46.2  million were
outstanding. They carry interest at a rate of 7.5% per annum, payable biannually
in March and  September.  During 2002,  the Company  repurchased  and  cancelled
$2,410,000  principal  amount of such bonds  resulting  in a $1.2  million  gain
recorded in other  income/expense.  In 2003 the Company further  repurchased and
cancelled  $1,345,000 principal amount of such bonds resulting in a gain of $0.6
million recorded in other  income/expense.  At the current  conversion rate, the
number of shares of Voting Common Stock to be issued on conversion  and exchange
of each unit of $10,000  comprised in a Bond would be 49. The conversion rate is
subject to adjustment in certain circumstances.

Related Party Loans

On June 11, 2002 LSR issued to Focus  Healthcare  Partners  ("FHP")  warrants to
purchase up to 410,914  shares of LSR Voting Common Stock at a purchase price of
$1.50 per share. The LSR warrants are exercisable at any time and will expire on
June 11, 2012. These warrants arose out of negotiations  regarding the provision
of a $2.9 million loan facility  made  available to the Company on September 25,
2000 by Mr.  Baker,  a director of the Company,  who controls FHP. This loan was
paid in full in 2002.  In  accordance  with APB 14 the  loan and  warrants  were
recorded at their pro rata fair values in relation to the proceeds received.  As
a result, the value of the warrants was $250,000.

Common Shares

On January 10, 2002, LSR issued 99,900 shares of Voting Common Stock and 900,000
shares of Non-Voting Common Stock at a price of $1.50 per share (or an aggregate
of $1.5  million).  Effective  July 25, 2002,  all of the 900,000  shares of the
Non-Voting  Common Stock were  converted  into 900,000  shares of Voting  Common
Stock.

On March 28, 2002, LSR closed the sale in a private placement of an aggregate of
5,085,334  shares of Voting  Common Stock at a price of $1.50 per share.  Of the
aggregate proceeds of approximately $7.6 million, $4.4 million was in cash, $2.4
million  represented  conversion  into  equity of debt owed to Mr.  Baker  ($2.1
million) and FHP ($0.3 million) and $825,000 was paid with  promissory  notes. A
net $141,000 of such promissory  notes was repaid during 2002, a net $23,000 was
repaid in 2003,  and a further  $18,000 was repaid in the first quarter of 2004,
offset by an increase due to foreign exchange movements of $23,000.

Cash flows

During the three  months  ended March 31,  2004,  funds used were $1.9  million,
reducing  cash and cash  equivalents  from $17.3 million at December 31, 2003 to
$15.4 million at March 31, 2004.

Net days sales outstanding  ("DSOs") at March 31, 2004 were 17 days, the same as
at December  31,  2003.  DSO is  calculated  as a sum of  accounts  receivables,
unbilled receivables and fees in advance over total revenue. Since January 1999,
DSOs at the quarter end have varied from 9 days to 47 days so they are currently
at a relatively low level.  The impact on liquidity from a one-day change in DSO
is approximately $210,000.

3.      CRITICAL ACCOUNTING POLICIES

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations discusses the Company's consolidated financial statements, which have
been prepared in accordance  with US GAAP.  The Company  considers the following
accounting policies to be critical accounting policies.

Revenue recognition

The majority of the  Company's  net revenues  have been earned under  contracts,
which generally range in duration from a few months to three years. Revenue from
these  contracts  is  generally  recognized  over the term of the  contracts  as
services are rendered. Contracts may contain provisions for renegotiation in the
event of changes in the level of work scope.  Renegotiated  amounts are included
in net revenue when earned and realization is assured.  Provisions for losses to
be incurred on  contracts  are  recognized  in full in the period in which it is
determined  that  a  loss  will  result  from  performance  of  the  contractual
arrangement.  Most service  contracts may be terminated for a variety of reasons
by the Company's customers,  either immediately or upon notice of a future date.
The  contracts  generally  require  payments  to the  Company to  recover  costs
incurred,  including costs to wind down the study, and payment of fees earned to
date,  and in some cases to provide  the  Company  with a portion of the fees or
income that would have been earned  under the contract had the contract not been
terminated early.

Unbilled  receivables  are  recorded  for  revenue  recognized  to date  that is
currently  not  billable to the  customer  pursuant  to  contractual  terms.  In
general,  amounts become billable upon the achievement of certain aspects of the
contract  or  in  accordance  with  predetermined  payment  schedules.  Unbilled
receivables  are  billable  to  customers  within  one year from the  respective
balance sheet date. Fees in advance are recorded for amounts billed to customers
for which,  revenue has not been  recognized  at the balance sheet date (such as
upfront  payments  upon  contract   authorization,   but  prior  to  the  actual
commencement of the study).

If the Company does not accurately  estimate the resources required or the scope
of work to be  performed,  or does not manage its projects  properly  within the
planned  periods of time or satisfy its  obligations  under the contracts,  then
future  margins  may be  significantly  and  negatively  affected  or  losses on
existing contracts may need to be recognized.  Any such resulting  reductions in
margins  or  contract  losses  could be  material  to the  Company's  results of
operations.

Use of estimates

The  preparation  of financial  statements in  conformity  with US GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities as of
the dates of the financial  statements and the results of operations  during the
reporting periods. These also include management estimates in the calculation of
pension  liabilities  covering  discount rates,  return on plan assets and other
actuarial assumptions. Although these estimates are based upon management's best
knowledge of current events and actions,  actual results could differ from those
estimates.

Taxation

The Company  accounts  for income  taxes under the  provisions  of  Statement of
Financial  Accounting  Standards ("SFAS") No. 109, "Accounting For Income Taxes"
("SFAS  109").  SFAS  109  requires  recognition  of  deferred  tax  assets  and
liabilities for the estimated future tax consequences of events  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
carry  forwards.  Deferred tax assets and liabilities are measured using enacted
rates in  effect  for the year in  which  the  differences  are  expected  to be
recovered  or settled.  The effect on  deferred  tax assets and  liabilities  of
changes in tax rates is  recognized in the statement of operations in the period
in which the enactment  rate changes.  Deferred tax assets and  liabilities  are
reduced  through the  establishment  of a valuation  allowance  at such time as,
based on  available  evidence,  it is more likely than not that the deferred tax
assets will not be realized.  While the Company has  considered  future  taxable
income and ongoing prudent and feasible tax planning strategies in assessing the
need  for the  valuation  allowance,  in the  event  that  the  Company  were to
determine  that it would not be able to realize all or part of its net  deferred
tax assets in the future,  an  adjustment  to the  deferred  tax assets would be
charged to income in the period such  determination was made.  Likewise,  should
the Company  determine  that it would be able to realize its deferred tax assets
in the  future  in excess  of its net  recorded  amount,  an  adjustment  to the
deferred tax assets would increase income in the period such  determination  was
made.

Exchange rate fluctuations and exchange controls

The Company operates on a world-wide basis and generally invoices its clients in
the  currency  of the  country in which it  operates.  Thus,  for the most part,
exposure to exchange rate  fluctuations  is limited as sales are  denominated in
the same currency as costs. Trading exposures to currency  fluctuations do occur
as a result of certain  sales  contracts,  performed  in the UK for US  clients,
which are  denominated  in US dollars and contribute  approximately  9% of total
revenues. Management has decided not to hedge against this exposure.

Also,  exchange  rate  fluctuations  may have an  impact on the  relative  price
competitiveness  of the Company vis a vis  competitors  who trade in  currencies
other than  sterling or dollars.  Such  fluctuations  also have an impact on the
translation of the 7.5% Convertible Capital Bonds payable in September 2006.

Finally,  the  consolidated  financial  statements of LSR are  denominated in US
dollars.  Changes in exchange  rates  between the UK pounds  sterling and the US
dollar will affect the translation of the UK subsidiary's financial results into
US dollars for the purposes of reporting the consolidated financial results. The
process by which each foreign subsidiary's financial results are translated into
US dollars is as follows:  income  statement  accounts are translated at average
exchange  rates for the period;  balance sheet asset and liability  accounts are
translated at end of period exchange rates;  and capital accounts are translated
at historical  exchange  rates and retained  earnings are translated at weighted
average of  historical  rates.  Translation  of the balance sheet in this manner
affects the stockholders'  equity account,  referred to as the accumulated other
comprehensive  loss  account.  Management  has decided not to hedge  against the
impact of exposures giving rise to these translation  adjustments as such hedges
may impact upon the Company's cash flow compared to the translation  adjustments
which do not affect cash flow in the medium term.

Exchange rates for translating sterling into US dollars were as follows:

              At December 31    At March 31    3 months to March 31 Average
                                                         rate (1)
     2002         1.6099           1.4240                 1.4266
     2003         1.7857           1.5807                 1.6031
     2004            -             1.8378                 1.8365

(1)  Based on the average of the exchange rates on each day of each month during
     the period.

On May 5, 2004 the noon buying rate for sterling was (pound)1.00 = $1.7932.

The  Company  has  not  experienced  difficulty  in  transferring  funds  to and
receiving funds remitted from those  countries  outside the US or UK in which it
operates and Management expects this situation to continue.

While the UK has not at this time  entered  the  European  Monetary  Union,  the
Company has ascertained  that its financial  systems are capable of dealing with
Euro denominated transactions.

The  following  table  summarizes  the  financial  instruments   denominated  in
currencies other than the US dollar held by LSR and its subsidiaries as of March
31, 2004:

4.      LEGAL PROCEEDINGS

The Company is party to certain legal  actions  arising out of the normal course
of its  business.  In  management's  opinion,  none of these actions will have a
material effect on the Company's  operations,  financial condition or liquidity.
No  form  of  proceedings  has  been  brought,  instigated  or  is  known  to be
contemplated against the Company by any governmental agency.

5.      FORWARD LOOKING STATEMENTS

Statements in this management's  discussion and analysis of financial  condition
and results of  operations,  as well as in certain other parts of this Quarterly
Report on Form 10-Q (as well as information included in oral statements or other
written statements made or to be made by the Company) that look forward in time,
are forward looking  statements  made pursuant to the safe harbor  provisions of
the Private Securities Litigation Reform Act of 1995. Forward looking statements
include  statements  concerning plans,  objectives,  goals,  strategies,  future
events or  performance,  expectations,  predictions,  and  assumptions and other
statements  which are other than  statements of historical  facts.  Although the
Company believes such forward-looking  statements are reasonable, it can give no
assurance that any  forward-looking  statements  will prove to be correct.  Such
forward-looking  statements  are subject  to, and are  qualified  by,  known and
unknown risks,  uncertainties and other factors that could cause actual results,
performance or achievements to differ materially from those expressed or implied
by those statements.  These risks,  uncertainties and other factors include, but
are not limited to the Company's  ability to estimate the impact of  competition
and of industry  consolidation  and risks,  uncertainties and other factors more
fully  described  in  the  Company's   filings  with  the  SEC,   including  its
Registration  Statement on Form S-1,  dated July 12, 2002,  and Annual Report on
Form  10-K  for the  year  ended  December  31,  2003,  each as  filed  with the
Securities and Exchange Commission.





ITEM 3  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's (pound)22.5 million  (approximately $41.1 million) credit facility
is sterling  denominated and does not contribute to transaction gains and losses
on the income  statement.  Interest  on all  outstanding  borrowings  under this
credit facility is based upon LIBOR plus a margin and  approximated  5.7819% per
annum for the three months  ended March 31, 2004.  At March 31, 2004 this credit
facility was fully drawn down.

In the three  months  ended  March 31,  2004,  a 1% change in LIBOR  would  have
resulted in a fluctuation in interest expense of $104,000.

For the three months ended March 31, 2004,  approximately  72% of the  Company's
net revenues were from outside the United States. The Company does not engage in
derivative  or hedging  activities  related to its  potential  foreign  exchange
exposures.

On March 31, 2004, the Company's $46.2 million  principal  amount of Convertible
Capital Bonds is US dollar  denominated,  but is held by a non-US  subsidiary of
the Company.  As a result,  with respect to these bonds, the Company experiences
exchange  related  gains and  losses  which  only has a  non-cash  impact on the
financial  statements,  based on the  movement of  exchange  rates.  Hence,  the
Company does not take any actions to hedge  against  such risks.  The Company is
unable to predict whether it will experience  future gains or future losses from
such exchange-related risks on the bonds.

See Management's  Discussion and Analysis of Financial  Condition and Results of
Operations.


ITEM 4            CONTROLS AND PROCEDURES

As of March 31, 2004 we carried out an  evaluation,  under the  supervision  and
with the participation of management,  including our Chief Executive Officer and
Chief Financial Officer, of the effectiveness of the design and operation of our
disclosure controls and procedures  pursuant to Exchange Act Rule 13a-15.  Based
upon that evaluation,  the Chief Executive  Officer and Chief Financial  Officer
concluded that our disclosure  controls and procedures  were effective as of the
quarter  ended March 31, 2004 in timely  alerting  them to material  information
relating to the Company (including its consolidated subsidiaries) required to be
included in our periodic SEC  filings.  During the quarter  ended March 31, 2004
there were no significant  changes in internal controls or in other factors that
has materially affected, or are reasonably likely to materially affect, internal
controls over financial reporting.
