                  LIFE SCIENCES RESEARCH, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                             March 31, 2003 and 2002
                                    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  world-wide
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 man uses,  eats, and is
otherwise exposed to. In addition,  it 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 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.  The Company  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 the  accounting  principles  generally  accepted  in the United  States of
America ("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 was accounted for as a "reverse acquisition" for
financial  reporting  purposes.  This reverse  acquisition  was deemed a capital
transaction  and the net assets of Huntingdon  (the  accounting  acquirer)  were
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. In these  financial
statements,  Huntingdon is the operating entity for financial reporting purposes
and the financial  statements for all periods presented  represent  Huntingdon's
financial  position  and  results  of  operations.  The  equity  of  LSR  is the
historical equity of Huntingdon, retroactively restated to reflect the number of
shares issued in the Exchange Offer, and all other stock offerings subsequent to
the Exchange Offer.

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,  2002,  2001 and 2000
included in LSR's Annual Report on Form 10-K for the fiscal year ended  December
31, 2002.  Operating results for the three-month period ended March 31, 2003 are
not  necessarily  indicative  of the results  that may be expected  for the year
ending December 31, 2003.


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  footnotes  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, 2003  compared  with three months ended March
     31, 2002.

Net revenues for the three  months ended March 31, 2003 were $31.9  million,  an
increase of 22.2% on net  revenues of $26.1  million for the three  months ended
March 31, 2002.  Excluding the effect of exchange rate  movements,  the increase
was 11.5%. UK net revenues  increased by 23.3%;  at constant  exchange rates the
increase  was 9.8%.  In the US,  net  revenues  increased  by 17.6%.  These both
reflect the growth in orders in 2002,  particularly  in the volume of toxicology
orders.  New signings for the three months ended March 31, 2003 were flat on the
same period last year.

Cost of revenues for the three  months ended March 31, 2003 were $25.4  million,
an increase of 17.1 % on cost of revenue of $21.7  million for the three  months
ended March 31, 2002.  Excluding  the effects of exchange  rate  movements,  the
increase was 7.1%.  This increase was driven by the  improvement in net revenues
though it was lower  than the  proportionate  increase  in net  revenues  as the
business is  characterized  generally by a high level of fixed costs. UK cost of
revenues  increased by 20.3%, at constant  exchange rates the increase was 7.1%,
reflecting  the  increase in volume,  mainly due to labor and  subcontract  cost
increases.  US cost of  revenues  increased  by 7.2%,  also as a  result  of the
increase in volume,  mainly due to labor cost increases and higher  depreciation
expense offset by lower subcontract costs.

Selling,  general  and  administrative  expenses (S G & A) rose by 14.0% to $4.9
million  for the three  months  ended  March 31,  2003 from $4.3  million in the
corresponding  period in 2002. Excluding the effects of exchange rate movements,
the  increase  was 4.7%.  The  increase  was due to higher  labor  costs of $0.4
million and higher commission  charges of $0.1 million.  UK S G & A increased by
20.9%;  at constant  exchange rates the increase was 7.6%. This increase was due
to the factors outlined above.

Net interest expense for the three months ended March 31, 2003 was $1.7 million,
which is $0.1 million higher than the net interest  expense for the three months
ended March 31, 2002.  Excluding the effects of exchange rate  movements,  there
was a net  decrease  of  5.6%,  due to  both  lower  interest  rates  and  lower
borrowings.

Other  expense in the three months ended March 31, 2003 of $0.5 million  relates
to the non-cash foreign exchange  remeasurement loss of $0.9 million 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 strengthening of the dollar against sterling; offset by $0.4 million gain on
the  repurchase of Capital Bonds.  In the three months to March 31, 2002,  other
expense of $2.6 million related to merger/offer  costs of $1.5 million  together
with the non-cash foreign exchange remeasurement loss of $1.1 million that arose
on the Convertible  Capital Bonds with the  strengthening  of the dollar against
sterling.

The income tax benefit on losses for the three  months  ended March 31, 2003 was
$0.2  million,  as a change in the UK tax laws meant that the  foreign  exchange
gains and  losses on the  Convertible  Capital  Bonds are  brought  into the tax
charge from  January 1, 2003.  The income tax benefit for the three months ended
March 31, 2002 was $0.7  million,  when the  exchange  gains on the  Convertible
Capital Bonds and merger costs were non-taxable. The disallowance of these items
for  tax  purposes  reduced  the  benefit  by  $0.2  million  and  $0.5  million
respectively.

The overall net loss for the three  months ended March 31, 2003 was $0.4 million
compared  to $3.3  million  for the  three  months  ended  March 31,  2002.  The
improvement  in the net  income of $2.9  million  is due to an  increase  in the
operating  income of $1.4  million,  a reduction in  merger/offer  costs of $1.5
million,  the gain on the  repurchase of the Capital Bonds of $0.4 million and a
reduction  in non-cash  foreign  exchange  remeasurement  loss of $0.2  million,
offset by a reduction in the income tax benefit of $0.5 million.

Basic loss per common share was 3 cents, compared to 48 cents last year.

2.       LIQUIDITY & CAPITAL RESOURCES

Bank Loan and Non-Bank Loans

On January 20, 2001,  the  Company's  current net non-bank  loan of  (pound)22.6
million ($36.0 million approximately) was refinanced by Stephens' Group Inc. and
other  parties.  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  such 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
Huntingdon  Life  Sciences  Group Plc and is  secured by the  guarantees  of the
wholly owned  subsidiaries  of the Company  including,  Huntingdon Life Sciences
Group Plc, Huntingdon Life Sciences Ltd., and Huntingdon Life Sciences Inc., and
collateralized  by all the assets of these  companies.  The loan was transferred
from Stephens  Group Inc., to an unrelated  third party  effective  February 11,
2002.

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 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.  The
warrants were subsequently transferred to an unrelated third party.

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. They carry  interest at a rate of 7.5% per
annum, payable biannually in March and September. During the three months ending
March 31, 2003, the Company  repurchased and cancelled $945,000 principal amount
of such bonds resulting in a $0.4 million gain recorded in other income/expense.
On April 11, 2003,  the Company  repurchased  and  cancelled a further  $450,000
principal  amount of such  bonds  resulting  in a gain of $0.2  million.  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

Other  financing  has been  provided  by a $2.952  million  loan  facility  made
available on September  25, 2000 by a director,  Mr. Baker.  In connection  with
this financing,  the company authorized,  subject to shareholder  approval,  the
issuance of warrants to purchase  410,914  shares of LSR Voting  Common Stock at
purchase  price of $1.50 per share to FHP, a company  controlled  by Mr.  Baker.
Such  shareholder  approval  was granted on June 12, 2002.  Additionally,  other
financing  also includes a $2.8 million  facility  from the Stephens  Group Inc.
made available on July 19, 2001.  Effective February 11, 2002 the Stephens Group
Inc. debt was transferred to an unrelated third party. Both facilities have been
fully drawn down.  $550,000 of the loan from Mr.  Baker was  transferred  to and
assumed by FHP in March 2001.  These loans from Mr. Baker and FHP are  repayable
on demand.  Although they are  subordinated to the bank debt, they are unsecured
and interest is payable  monthly at a rate of 10% per annum.  On March 28, 2002,
$2.1 million of Mr.  Baker's loan was  converted  into  1,400,000  shares of LSR
Voting Common Stock and $300,000 of FHP's loan was converted into 200,000 shares
of LSR Voting Common Stock;  in each case as part of LSR's private  placement of
approximately  5.1 million  shares of Voting Common  Stock.  As a result of such
conversions,  $302,000  remained  payable  to Mr.  Baker and  $250,000  remained
payable to FHP as of December 31, 2002. On March 24, 2003,  $128,000 of the loan
was repaid to Mr.  Baker.  On April 5, 2003 the Company  repaid the remainder of
both of these loans.  Interest  was payable  monthly at a rate of 10% per annum.
One half of the  facility  was repaid on July 1,  2002,  and the  remainder  was
repaid on October 1, 2002.

As noted  above,  on June 11, 2002 LSR issued to 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 the
$2.9 million loan facility  made  available to the Company on September 25, 2000
by Mr. Baker,  who controls FHP. 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.
$222,000 of such  promissory  notes was repaid during 2002 and a further $63,000
was repaid in the first quarter 2003.

Cash flows

During the three  months  ended March 31,  2003,  funds used were $3.5  million,
reducing  cash and cash  equivalents  from $14.6 million at December 31, 2002 to
$11.1 million at March 31, 2003.

Net days sales outstanding  ("DSOs") at March 31, 2003 were 13 days, up slightly
from the 9 days at December 31,  2002.  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 $290,000.

3.       SIGNIFICANT 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 significant 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 cost  overruns due to 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.  The Company's  customers  may terminate  most service
contracts  for a variety of  reasons,  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.

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  7.5% of total
revenues. Management have decided not to hedge against this exposure.

Secondly,  exchange  rate  fluctuations  have an  impact on the  relative  price
competitiveness  of the Company vis a vis  competitors  who trade in  currencies
other than sterling or dollars.

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 equity accounts are translated
at historical  exchange  rates.  Translation of the balance sheet in this manner
affects the stockholders'  equity account,  referred to as the accumulated other
comprehensive  loss  account.  Management  have 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 US dollars into sterling were as follows:

              At December 31      At March 31      3 months to March 31 Average
                                                             rate (1)
   2001           0.6871             0.7034                   0.6917
   2002           0.6212             0.7022                   0.7010
   2003              -               0.6326                   0.6238

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

On May 8, 2003 the noon buying rate for sterling was $1.00 = (pound)0.6244.

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, 2003:

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  date 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.

4.        NEW ACCOUNTING STANDARDS

In August 2001, the FASB issued SFAS No. 143,  "Accounting for Asset  Retirement
Obligations" ("SFAS 143"). This statement is effective for financial  statements
issued for fiscal years  beginning on or after June 15, 2002.  SFAS 143 requires
entities  to  record  the fair  value  of a  liability  for an asset  retirement
obligation in the period in which it is incurred.  When a liability is initially
recorded, the entity capitalizes a cost by increasing the carrying amount of the
related  long-lived  asset.  Over time, the liability is accreted to its present
value each period,  and the capitalized cost is depreciated over the useful life
of the related asset. Upon settlement of the liability, an entity either settles
the obligation for its recorded amount or incurs a gain or loss upon settlement.
LSR does not believe  that the adoption of this  statement  will have a material
impact on LSR's results of operations, financial position or cash flows.

In April 2002, the FASB issued SFAS No. 145,  "Rescission of FASB Statements No.
4, 44, and 64,  Amendment of FASB  Statement No. 13, and Technical  Corrections"
("SFAS 145").  This statement is effective  fiscal years beginning after May 15,
2002.  SFAS  145  rescinds  SFAS  No.  4,  "Reporting   Gains  and  Losses  from
Extinguishment  of Debt"  (SFAS 4),  which  required  all gains and losses  from
extinguishment  of debt to be  aggregated  and, if  material,  classified  as an
extraordinary  item, net of related income tax effect. As a result, the criteria
in Opinion 30 will now be used to classify those gains and losses. SFAS 145 also
amends  Statement  13 to require  that  certain  lease  modifications  that have
economic effects similar to sale-leaseback  transactions be accounted for in the
same  manner as  sale-leaseback  transactions.  The  Company  early  adopted the
provisions of this statement,  resulting in the inclusion of a $0.4 million gain
in other income/(expense) in 2003.

In June 2002,  the FASB issued SFAS No. 146,  "Accounting  for Costs  Associated
with Exit or Disposal Activities" (SFAS 146). SFAS 146 requires that a liability
for a cost associated  with an exit or disposal  activity be recognized when the
liability is incurred.  SFAS 146 eliminates the definition and  requirement  for
recognition  of exit costs in Emerging  Issues Task Force  (EITF) Issue No. 94-3
where a liability  for an exit costs was  recognized  at the date of an entity's
commitment  to an exit plan.  This  statement is effective  for exit or disposal
activities  initiated  after  December 31,  2002.  LSR does not believe that the
adoption  of this  statement  will  have a  material  impact on its  results  of
operations, financial position or cash flows.

In June 2002, the FASB issued  Statement No. 148,  "Accounting  for  Stock-Based
Compensation  - Transition  and  Disclosure,  an amendment of FASB Statement No.
123" ("SFAS 148"). This statement amends FASB Statement No. 123,  Accounting for
Stock-Based  Compensation,  to provide  alternative  methods of transition for a
voluntary  change to the fair value based method of accounting  for  stock-based
employee  compensation.  In  addition,  this  statement  amends  the  disclosure
requirements  of Statement 123 to require  prominent  disclosures in both annual
and interim financial  statements about the method of accounting for stock-based
employee compensation and the effect of the method used on reported results. The
amendments to Statement 123 of this  statement  shall be effective for financial
statements for fiscal years ending after December 15, 2002. The adoption of this
statement had no impact on LSR's results of  operations,  financial  position or
cash flows.

In  November  2002,  the FASB issued FASB  interpretation  No. 45,  "Guarantor's
Accounting  and  Disclosure  Requirements  for  Guarantees,  including  Indirect
Guarantees of  Indebtedness  of Others".  In the normal course of business,  the
Company  does  not  issue  guarantees  to  third  parties;   accordingly,   this
interpretation has no effect on the Company's financial statements.

In January 2003, the FASB issued FASB  Interpretation No. 46,  "Consolidation of
Variable  Interest  Entities"  ("FIN  46").  FIN 46  requires  certain  variable
interest entities to be consolidated by the primary beneficiary of the entity if
the  equity  investors  in the  equity  do not  have  the  characteristics  of a
controlling  financial interest or do not have sufficient equity at risk for the
entity to finance  its  activities  without  additional  subordinated  financial
support from other parties. FIN 46 is effective immediately for all new variable
interest entities created or acquired after January 15, 2003. The Company has no
arrangements that would be subject to this interpretation.

5.       SUBSEQUENT EVENTS

On April 5, 2003,  the Company  fully repaid the remainder of the Baker loan and
FHP loan of $122,000 and $302,000 respectively.

On April 11, 2003,  the Company  repurchased  and cancelled  $450,000  principal
amount of the  Convertible  Capital  Bonds,  repayable in September  2006.  This
resulted in a gain of $0.2 million.

6.       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.

7.     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  Registration Statement on Form S-1, dated July
12, 2002,  and Annual Report on Form 10-K for the year ended  December 31, 2002,
each as filed with the Securities and Exchange Commission.


ITEM 3            QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company's  (pound)22.6  million ($35.7  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  5.74% per annum for
the three months ended March 31,  2003.  At March 31, 2003 this credit  facility
was fully drawn down.

In the three  months  ended  March 31,  2003,  a 1% change in LIBOR  would  have
resulted in a fluctuation in interest expense of $88,000.

For the three months ended March 31, 2003,  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, 2003, the Company's $46.6 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

Within  the 90 days  prior  to the  date  of  this  report,  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-14. Based upon that evaluation, the
Chief  Executive   Officer  and  Chief  Financial  Officer  concluded  that  our
disclosure  controls and  procedures  are  effective in timely  alerting them to
material  information  relating  to  the  Company  (including  its  consolidated
subsidiaries)  required to be included in our periodic  SEC filings.  There have
been no significant  changes in internal controls or in other factors that could
significantly affect internal controls subsequent to the date of our most recent
evaluation.

I, Andrew Baker, as Chief Executive Officer of the Company, certify that:

1.   I have  reviewed  this  quarterly  report  on Form  10-Q  of Life  Sciences
     Research, Inc.:

2.   Based on my knowledge,  this  quarterly  report does not contain any untrue

          employees who have a  significant  role in the  registrant's  internal
          controls; and

6.   The  registrant's  other  certifying  officers and I have indicated in this
     quarterly report whether or not there were significant  changes in internal
     controls  or in other  factors  that could  significantly  affect  internal
     controls  subsequent to the date of our most recent  evaluation,  including
     any corrective actions with regard to significant deficiencies and material
