                  LIFE SCIENCES RESEARCH, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                             June 30, 2005 and 2004
                                    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.

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

Organization

LSR,  incorporated in Maryland on July 19, 2001, was formed specifically for the
purpose of acquiring  Life Sciences  Research Ltd (LSR Ltd) formerly  Huntingdon
Life Sciences Group plc  ("Huntingdon"),  which has been in business since 1952.
The Offer was declared  unconditional on January 10, 2002, and LSR completed the
purchase of all  outstanding  ordinary shares of Huntingdon on March 26, 2002 at
which time  Huntingdon  became a wholly owned  subsidiary of LSR (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.

On June 14, 2005,  the Company  entered into and  consummated  purchase and sale
agreements   with  Alconbury   Estates  Inc.  and   subsidiaries   (collectively
"Alconbury")  for the  sale  and  leaseback  of the  Company's  three  operating
facilities in Huntingdon and Eye,  England and East  Millstone,  New Jersey (the
"Sale/Leaseback Transaction").  Alconbury is a newly formed company wholly owned
by LSR's  Chairman  and CEO,  Andrew  Baker.  The  total  consideration  paid by
Alconbury for the three  properties  was $40 million,  consisting of $30 million
cash and a five year, $10 million  variable rate  subordinated  promissory note,
which Alconbury has agreed to make a best effort to repay within twelve months.

The proceeds from the Sale/Leaseback  Transaction (plus additional cash on hand)
were used by the Company to pay in full its  (pound)22.6  million  non-bank debt
(approximately $41.1 million).

In accordance with the provisions of FASB  Interpretation No. 46R (FIN 46R), the
Company will reflect the  consolidation of Alconbury as long as it is considered
the "primary  beneficiary" of Alconbury's  variable interests.  The Company will
not record the gain and loss  associated  with the sale of the  properties,  nor
recognize the associated changes in depreciation,  interest,  and rent expenses,
until FIN 46R  consolidation  accounting no longer  applies.  At that time,  the
Company will record a non-cash loss of approximately $44 million for the sale of
the UK properties,  and a gain of approximately  $6 million,  amortized over the
term of the lease, for the US property.  In addition,  the Company anticipates a
net reduction in its annual  depreciation  charge of approximately  $2.7million,
offset by a net  increase of $0.5  million in interest  and rent  expenses.  The
Company  anticipates  that it will  no  longer  be the  primary  beneficiary  of
Alconbury when the $10 million subordinated promissory note has been repaid.

2.       SIGNIFICANT ACCOUNTING POLICIES

i)       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,  2004,  2003 and 2002
included in LSR's Annual Report on Form 10-K for the fiscal year ended  December
31, 2004. Operating results for the three-month and six month periods ended June
30, 2005 are not necessarily  indicative of the results that may be expected for
the year ending December 31, 2005.

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 US GAAP have been omitted in accordance with Rule 10-01 of Regulation S-X.

ii)      Stock-Based Compensation

The Company  has stock  option and  stock-based  compensation  plans,  which are
described in detail in our audited consolidated financial statements included in
our Annual Report on Form 10-K for the year ended  December 31, 2004.  Under the
Long Term  Incentive Plan (LTIP),  the Company  granted  362,663  ten-year stock
options to  executives  on June 1, 2004.  All such  options were granted with an
exercise price equal to the market price of the underlying  stock on the date of
the grant.  These options will vest 100% on March 31, 2007 for those  executives
who remain employed with the Company through that date.

Effective  January  1,  2003,  the  Company  adopted  FASB  Statement  No.  148,
Accounting for Stock-Based  Compensation - Transition and Disclosure.  Statement
No. 148 amends FASB Statement No. 123, Accounting for Stock-Based  Compensation,
to  provide,  among  other  things,  prominent  disclosure  of the effects of an
entity's accounting policy with respect to stock-based employee  compensation on
reported  net income and  earnings  per share in annual  and  interim  financial
statements.  The  Company  intends to  continue  to follow  the  disclosure-only
provisions of FASB Statement No. 123 and, accordingly,  will continue to account
for these plans under the recognition and measurement  principles of APB Opinion
No. 25, Accounting for Stock Issued to Employees,  and related  interpretations.
Under APB 25, when stock options are issued with an exercise  price equal to the
market  price of the  underlying  stock on the date of  grant,  no  compensation
expense is recognized.



ii)      Stock-Based Compensation (cont'd)

No  compensation  cost is recorded for options  granted under the Company's plan
since all options  granted are issued with an exercise price equal to the market
value of the  underlying  common stock on the date of grant,  and employees must
pay for these stock issuances. The following table illustrates the effect on net
income and earnings  per share for the three and six months ended June,  30 2005
and 2004 had the Company applied the fair value  recognition  provisions of FASB
Statement  No.123,  Accounting  for  Stock-Based  Compensation,  to  all  of its
stock-based employee compensation plans.

The per share weighted average fair value of stock options granted was $7.74 and
$1.82  during the three months  ended June 30, 2005 and 2004  respectively,  and
$7.74 and $1.82 during the six months ended June 30, 2005 and 2004 respectively.
The HLS options  granted prior to 2002 are  considered  to have no value.  These
fair values were estimated using the Black-Scholes  option-pricing  model, based
on the following assumptions:

4.       REFINANCING

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 Focused Healthcare Partners ("FHP") ($0.3 million) and $825,000 was
paid with promissory  notes. A net $128,000 of such promissory  notes was repaid
to the end of 2004,  and a further  net  $436,000  was repaid to the end of June
2005.

On June 14, 2005, the Company entered into and  consummated  the  Sale/Leaseback
Transaction with Alconbury.  Alconbury is a newly formed company wholly owned by
LSR's Chairman and CEO, Andrew Baker. The total  consideration paid by Alconbury
for the three  properties was $40 million,  consisting of $30 million cash and a
five year,  $10  million  variable  rate  subordinated  promissory  note,  which
Alconbury  has agreed to make a best effort to repay within twelve  months.  The
Company  has  agreed  to  pay  the   expenses   incurred  by  Alconbury  in  the
Sale/Leaseback Transaction of approximately $4.5 million, subject to Alconbury's
obligation to reimburse those expenses in the future.  Such reimbursement  shall
be made in equal installments in each year of the five year period beginning the
third  anniversary  of June 14,  2005,  the closing  date of the  Sale/Leaseback
Transaction.

Due to the consolidation  resulting from the Company's  adoption of FIN 46R, the
Company's financial statements reflect a loan by an unrelated third party in the
aggregate principal amount of $30 million. This loan has a term date of June 14,
2006, with the right to extend the term up to an additional one-year.  Alconbury
intends to refinance  this debt on a long term basis prior to the maturity  date
of June  14,  2006.  However,  if the  long  term  financing  is not  available,
Alconbury intends to exercise the one-year renewal option, and accordingly,  has
classified  the loan as  long-term  debt.  The  loan,  which  carries  an annual
interest rate of 15%, has been secured by first priority lien on all the assets,
including the facilities, of Alconbury, and is also personally guaranteed by the
owner  of  Alconbury.   This  loan  is  currently   payable  in  twelve  monthly
installments of interest only, with a balloon payment of $30 million due on June
14, 2006.

As part of the Sale/Leaseback  Transaction,  the Company (through  subsidiaries)
entered  into  thirty year leases with  Alconbury  for each  facility,  with two
five-year renewal options. Base aggregate annual rent for the facilities is $4.9
million  (approximately $1.8 million in the US and approximately $3.1 million in
the UK) which amount will increase by 3% each year for the UK facilities  and by
an amount equal to the annual US consumer price index for the US facility. Under
the terms of the leases,  no  security  deposit was  initially  required,  but a
three-month  security  deposit  will be  required  at such time  that  Alconbury
refinances its current financing arrangements.  Additionally, because the leases
are "triple net" leases,  LSR will also pay for all of the costs associated with
the operation of the facilities,  including  costs such as insurance,  taxes and
maintenance.

Since the Sale/Leaseback  Transaction was with a related party (Mr. Baker, LSR's
Chairman and CEO and the owner of Alconbury),  an Independent Committee of LSR's
Board of  Directors  (the  "Committee")  was formed to analyze and  consider the
proposed  Sale/Leaseback  Transaction.  The Committee was comprised of the three
independent directors of LSR: Gabor Balthazar, Afonso Junqueiras and Yaya Sesay.
The Committee retained  independent legal and financial advisors to assist it in
its analysis.  The Committee and LSR's senior  management (other than Mr. Baker)
negotiated the key terms and provisions of the  Sale/Leaseback  Transaction with
Alconbury.  The  Committee  also  obtained  appraisals  of the  facilities  from
independent real estate appraisal firms.

The proceeds from the Sale/Leaseback  Transaction (plus additional cash on hand)
were used by the Company to pay in full its  (pound)22.6  million  non-bank debt
(approximately $41.1 million).

In accordance with the provisions of FASB  Interpretation No. 46R (FIN 46R), the
Company will reflect the  consolidation of Alconbury as long as it is considered
the "primary  beneficiary" of Alconbury's  variable interests.  The Company will
not record the gain and loss  associated  with the sale of the  properties,  nor
recognize the associated changes in depreciation,  interest,  and rent expenses,
until FIN 46R  consolidation  accounting no longer  applies.  At that time,  the
Company will record a non-cash loss of approximately $44 million for the sale of
the UK properties,  and a gain of approximately  $6 million,  amortized over the
term of the lease, for the US property.  In addition,  the Company anticipates a
net reduction in its annual  depreciation  charge of approximately  $2.7million,
offset by a net  increase of $0.5  million in interest  and rent  expenses.  The
Company  anticipates  that it will  no  longer  be the  primary  beneficiary  of
Alconbury when the $10 million subordinated promissory note has been repaid.


5.       COMMITMENTS AND CONTINGENCIES

(i)  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.

(ii) The Compensation  Committee approved as of June 1, 2004 a performance based
     cash bonus award for  executives.  This award,  issued  under the Long Term
     Incentive Plan (LTIP),  will award cash compensation to select  individuals
     if certain performance goals relating to operations are reached by December
     31,  2006.  The  amount  of the  award  varies  based  upon  the  level  of
     performance,  with a complete  default  of the award if  minimum  operating
     levels are not achieved.

     Management is ratably accruing, as compensation expense, an amount equal to
     the currently estimated cash bonus over the performance period.  Management
     will  re-evaluate  this estimate  periodically  throughout the  performance
     period and, if applicable, will adjust the estimate accordingly.





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

1.       RESULTS OF OPERATIONS

a)   Three months ended June 30, 2005  compared with three months ended June 30,
     2004.

Net  revenues for the three  months  ended June 30 2005 were $44.9  million,  an
increase of 17.3% on net  revenues of $38.3  million for the three  months ended
June 30, 2004. Excluding the effect of exchange rate movements, the increase was
14.9%.  UK net  revenues  increased  by 15.9%;  at constant  exchange  rates the
increase was 13.0%. This growth in revenues reflects the increase in orders and,
consequently,  backlog over the last year,  principally from the  pharmaceutical
industry.  Also reflected in the quarter were revenues  associated with the post
life phase of an unusually large number of long-term studies,  much of which was
subcontracted  due to capacity  constraints.  This  increased  revenues  for the
quarter by  approximately  $1.2  million.  In the US, net revenues  increased by
22.1%. The growth in revenues in the US reflects the increase in orders from the
pharmaceutical industry.

Cost of revenues for the three months ended June 30, 2005 were $32.5 million, an
increase  of 15.5% on cost of revenues  of $28.1  million  for the three  months
ended June 30,  2004.  Excluding  the effects of exchange  rate  movements,  the
increase was 13.0%. UK cost of revenues increased by 14.7%; at constant exchange
rates there was a increase of 11.7%. Reflected in the quarter were costs of $0.6
million associated with subcontracting the post life phase of an abnormal number
of long-term  studies.  US cost of revenues  increased by 17.8%  reflecting  the
growth in revenues.

Selling,  general  and  administrative  expenses  (SG&A)  rose by  14.1% to $7.1
million  for the three  months  ended  June 30,  2005 from $6.2  million  in the
corresponding  period in 2004. Excluding the effects of exchange rate movements,
the  increase was 11.7%.  The  increase  was mainly due to  increased  costs for
headquarters  salary and bonuses,  higher  insurance  costs,  and some increased
selling and administrative salary costs.

Net interest  expense for the three months ended June 30, 2005 was $1.9 million,
which was $0.3 million higher than the net interest expense for the three months
ended June 30,  2004.  Excluding  the effects of exchange  rate  movements,  the
increase  was  mainly  due to an  increase  in LIBOR and costs  associated  with
foreign currency hedging.

Other  expense  in the  three  months  ended  June 30,  2005  was  $2.7  million
reflecting a non-cash foreign exchange re-measurement loss of $2.4 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 and finance arrangement fees of
$0.3  million.  In the three months ended June 30, 2004,  other  expense of $0.6
million related to the non-cash foreign exchange  re-measurement loss that arose
on the Convertible  Capital Bonds,  with the strengthening of the dollar against
sterling.

The income tax  expense on income for the three  months  ended June 30, 2005 was
$2.5 million. This expense includes $2.4 million in respect of the tax liability
on the sale of the  Company's US facility.  The income tax expense for the three
months ended June 30, 2004, was $0.6 million. Net operating losses in the US are
$6.5  million at June 30,  2005;  with net  operating  losses in the UK of $59.3
million.



The overall net loss for the three  months  ended June 30, 2005 was $1.7 million
compared to $1.2  million net income for the three  months  ended June 30, 2004.
The  decrease  in the  net  income  of $2.9  million  is due to an  increase  in
operating  income of $1.4  million;  offset by an increase  in non-cash  foreign
exchange  re-measurement  loss of $2.1 million, an increase in interest expenses
of $0.3 million and an increase in the income tax expense of $1.9 million.

Basic loss per common  share was 13 cents,  compared  to 10 cents  income in the
same period last year,  on the weighted  average  common shares  outstanding  of
12,520,880  (2004:  12,049,534).  Diluted  loss per diluted  share was 11 cents,
compared to 10 cents income in the same period last year.

Excluding the Other Expense items  described  above related to non-cash  foreign
exchange losses, and related tax effect, and the transaction related tax charges
net income for the quarter  ended June 30, 2005 was $3.0  million,  or $0.21 per
fully diluted share, compared with $1.7 million or $0.14 per fully diluted share
for the same period in the prior year.

Earnings  before  interest,  taxes,  depreciation  and  amortization,  and other
income/(expense)  ("EBITDA") was $7.9 million for the second quarter of 2005, or
17.5% of revenues, compared with $6.3 million, or 16.4% of revenues for the same
period in the prior year.

This  Quarterly  Report  on Form  10-Q  contains  non-GAAP  financial  measures,
including  EBITDA and  non-GAAP  earnings per share which  exclude,  among other
items,   gains  or  losses   associated  with  the  non-cash   foreign  exchange
remeasurement loss pertaining to the Company's Convertible Capital Bonds and one
time  charges.  We exclude  these  items from the  non-GAAP  financial  measures
because they are outside our normal operations. We believe that the inclusion of
non-GAAP  financial  measures  in  this  Quarterly  Report  on Form  10-Q  helps
investors to gain a meaningful  understanding of our core operating  results and
future prospects,  and is consistent with how management  measures and forecasts
the  Company's  performance  and  debt  service  capabilities,  especially  when
comparing  such results to prior  periods or  forecasts.  Non-GAAP  results also
allow  investors  to compare the  Company's  operations  against  the  financial
results of other  companies  in the  industry  who  similarly  provide  non-GAAP
results.  The non-GAAP  financial  measures included in this Quarterly Report on
Form 10-Q are not meant to be considered superior to or a substitute for results
of operations prepared in accordance with GAAP.  Reconciliations of the non-GAAP
financial  measures  used in this  Quarterly  Report  on Form  10-Q to the  most
directly  comparable  GAAP financial  measures are set forth in the text of this
Quarterly Report on Form 10-Q and other public filings, and can also be found on
the Company's website at www.lsrinc.net.

b)   Six months ended June 30 2005 compared with six months ended June 30, 2004

Net  revenues  for the six months  ended June 30,  2005 were $88.2  million,  an
increase of 16.8% on net revenues of $75.6 million for the six months ended June
30, 2004.  Excluding  the effect of exchange  rate  movements,  the increase was
14.3%.  UK net  revenues  increased  by 15.3%;  at constant  exchange  rates the
increase was 12.2%. This growth in revenues reflects the increase in orders and,
consequently,  backlog over the last year,  principally from the  pharmaceutical
industry.  Also  reflected in the six months were revenues  associated  with the
post life phase of an unusually large number of long-term studies, much of which
was subcontracted due to capacity  constraints.  This increased revenues for the
six months by approximately  $1.5 million.  In the US, net revenues increased by
22.6%. The growth in revenues in the US reflects the increase in orders from the
pharmaceutical industry.

Cost of revenues for the six months ended June 30, 2005 were $63.5  million,  an
increase of 10.4 % on cost of revenue of $57.5  million for the six months ended
June 30, 2004.  Excluding the effects of exchange rate  movements,  the increase
was 8.0%. UK cost of revenues increased by 16.1%; at constant exchange rates the
increase  was 6.0%.  Reflected  in the six  months  were  costs of $0.7  million
associated  with  subcontracting  the post life phase of an  abnormal  number of
long-term studies.  US cost of revenues increased by 16.1% reflecting the growth
in revenues.

Selling,  general  and  administrative  expenses  (SG&A)  rose by 20.5% to $14.1
million  for the six  months  ended  June 30,  2005 from  $11.7  million  in the
corresponding  period in 2004. Excluding the effects of exchange rate movements,
the increase  was 18.2%.  This  increase  was mainly due to increased  costs for
headquarters  salary and bonuses,  higher  insurance  costs,  and some increased
selling and administrative salary costs.

Net interest  expense for the six months  ended June 30, 2005 was $3.7  million,
which was $0.6 million  higher than the net interest  expense for the six months
ended June 30,  2004.  Excluding  the effects of exchange  rate  movements,  the
increase  was mainly due to an increase in LIBOR and the costs  associated  with
foreign currency hedging.

Other expense in the six months ended June 30, 2005 was $3.4 million  reflecting
a non-cash  foreign exchange  remeasurement  loss of $3.1 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 and finance  arrangement  fees of
$0.3  million.  In the six months  ended  June 30,  2004,  other  income of $0.7
million related to the non-cash foreign exchange  remeasurement  gain that arose
on the  Convertible  Capital  Bonds with the  weakening  of the  dollar  against
sterling.

The income tax expense on income for the six months ended June 30, 2005 was $2.6
million.  This expense  includes $2.4 million in respect of the tax liability on
the sale of the Company's US facility. The income tax expense for the six months
ended June 30, 2004 was $1.3 million.

The overall net income for the six months  ended June 30, 2005 was $0.9  million
compared to $2.6 million for the six months ended June 30, 2004. The decrease in
the net income of $1.7 million is due to an increase in the operating  income of
$4.3 million;  offset by a decrease in non-cash foreign  exchange  remeasurement
loss of $4.1 million,  an increase in interest  expense of $0.6 million,  and an
increase in the income tax expense of $1.3 million.

Basic income per common share was 7 cents, compared to 22 cents last year on the
weighted  average common shares  outstanding of 12,487,442  (2004:  12,044,704).
Diluted income per diluted share was 6 cents,  compared to 21 cents for the same
period in the prior year.

Excluding the Other Expense items  described  above related to non-cash  foreign
exchange losses, and related tax effect, and the transaction related tax charges
net income for the first six months of 2005 was $6.2  million or $0.43 per fully
diluted  share,  compared with $2.0 million or $0.16 per fully diluted share for
the same period in the prior year.

EBITDA for the six months  ended June 30,  2005 was $15.4  million,  or 17.5% of
revenues,  compared  with $10.9 million or 14.5% of revenues for the same period
in 2004.

2.       LIQUIDITY & CAPITAL RESOURCES

Non-Bank Loans

On  January  20,  2001,  the  Company's  non-bank  loan of  (pound)22.6  million
($41.1million  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 was repayable on June 30, 2006 and
interest was 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 was
held by Life Sciences Research Ltd (LSR Ltd.), and was 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 June 14, 2005 this non-bank loan was fully repaid
using the proceeds from the Sale/Leaseback Transaction and cash on hand.

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.  154,425 of such
warrants were exercised in 2004.

On June 14, 2005, the Company entered into and  consummated  the  Sale/Leaseback
Transaction with Alconbury.  Alconbury is a newly formed company wholly owned by
LSR's Chairman and CEO, Andrew Baker. The total  consideration paid by Alconbury
for the three  properties was $40 million,  consisting of $30 million cash and a
five year,  $10  million  variable  rate  subordinated  promissory  note,  which
Alconbury  has agreed to make a best effort to repay within twelve  months.  The
Company  has  agreed  to  pay  the   expenses   incurred  by  Alconbury  in  the
Sale/Leaseback Transaction of approximately $4.5 million, subject to Alconbury's
obligation to reimburse those expenses in the future.  Such reimbursement  shall
be made in equal  instalments in each year of the five year period beginning the
third  anniversary  of June 14,  2005,  the closing  date of the  Sale/Leaseback
Transaction.

As part of the Sale/Leaseback  Transaction,  the Company (through  subsidiaries)
entered  into  thirty year leases with  Alconbury  for each  facility,  with two
five-year renewal options. Base aggregate annual rent for the facilities is $4.9
million  (approximately $1.8 million in the US and approximately $3.1 million in
the UK) which amount will increase by 3% each year for the UK facilities  and by
an amount equal to the annual US consumer price index for the US facility. Under
the terms of the leases,  no  security  deposit was  initially  required,  but a
three-month  security  deposit  will be  required  at such time  that  Alconbury
refinances its current financing arrangements.  Additionally, because the leases
are "triple net" leases,  LSR will also pay for all of the costs associated with
the operation of the facilities,  including  costs such as insurance,  taxes and
maintenance.

Since the Sale/Leaseback  Transaction was with a related party (Mr. Baker, LSR's
Chairman and CEO and the owner of Alconbury),  an Independent Committee of LSR's
Board of  Directors  (the  "Committee")  was formed to analyze and  consider the
proposed  Sale/Leaseback  Transaction.  The Committee was comprised of the three
independent directors of LSR: Gabor Balthazar, Afonso Junqueiras and Yaya Sesay.
The Committee retained independent legal and financial advisors to assist in its
analysis.  The  Committee  and LSR's senior  management  (other than Mr.  Baker)
negotiated the key terms and provisions of the  Sale/Leaseback  Transaction with
Alconbury.  The  Committee  also  obtained  appraisals  of the  facilities  from
independent real estate appraisal firms.

The proceeds from the Sale/Leaseback  Transaction (plus additional cash on hand)
were used by the Company to pay in full its  (pound)22.6  million  non-bank debt
(approximately $41.3 million).

In accordance with the provisions of FASB  Interpretation No. 46R (FIN 46R), the
Company will reflect the  consolidation of Alconbury as long as it is considered
the "primary  beneficiary" of Alconbury's  variable interests.  The Company will
not record the gain and loss  associated  with the sale of the  properties,  nor
recognize the associated changes in depreciation,  interest,  and rent expenses,
until FIN 46R  consolidation  accounting no longer  applies.  At that time,  the
Company will record a non-cash loss of approximately $44 million for the sale of
the UK properties,  and a gain of approximately  $6 million,  amortized over the
term of the lease, for the US property.  In addition,  the Company anticipates a
net reduction in its annual  depreciation  charge of approximately  $2.7million,
offset by a net  increase of $0.5  million in interest  and rent  expenses.  The
Company  anticipates  that it will  no  longer  be the  primary  beneficiary  of
Alconbury when the $10 million subordinated promissory note has been repaid.

Due to the consolidation  resulting from the Company's  adoption of FIN 46R, the
Company's financial statements reflect a loan by an unrelated third party in the
aggregate principal amount of $30 million. This loan has a term date of June 14,
2006, with the right to extend the term up to an additional one-year.  Alconbury
intends to refinance  this debt on a long term basis prior to the maturity  date
of June  14,  2006.  However,  if the  long  term  financing  is not  available,
Alconbury intends to exercise the one-year renewal option, and accordingly,  has
classified  the loan as  long-term  debt.  The  loan,  which  carries  an annual
interest rate of 15%, has been secured by first priority lien on all the assets,
including the facilities, of Alconbury, and is also personally guaranteed by the
owner  of  Alconbury.   This  loan  is  currently   payable  in  twelve  monthly
installments of interest only, with a balloon payment of $30 million due on June
14, 2006.

Convertible Capital Bonds

The remainder of the Company's  long term  financing is provided by  Convertible
Capital Bonds repayable on September 25, 2006. At the time of the issue in 1991,
these bonds were for $50 million par and at June 30,  2005,  $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  $1,395,000 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 Transactions

On June 11, 2002 LSR issued to Focused  Healthcare  Partners ("FHP"),  an entity
controlled by Andrew Baker, the Company's Chairman and CEO, 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.  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.

On June 14, 2005,  the Company  completed the  Sale/Leaseback  Transaction  with
Alconbury, a company formed by Mr Baker, LSR's Chairman and CEO. The Company has
agreed  to  pay  the  expenses  incurred  by  Alconbury  in  the  Sale/Leaseback
Transaction of approximately $4.5 million,  subject to Alconbury's obligation to
reimburse  those  expenses in the future.  Such  reimbursement  shall be made in
equal  instalments  in each year of the five  year  period  beginning  the third
anniversary  of  June  14,  2005,   the  closing  date  of  the   Sale/Leaseback
Transaction.

Alconbury  has  received  an  interest  free  loan of  $250,000,  which has been
included in accrued  expenses and other  liabilities,  from Andrew Baker,  LSR's
Chairman and CEO.

Common Shares

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  $128,000  of such  promissory  notes was  repaid to the end of 2004,  and a
further net $436,000 was repaid to the end of June 2005.

Cash flows

During the three  months  ended June 30,  2005,  funds used were $14.5  million,
reducing cash and cash equivalents from $29.9 million at March 31, 2005 to $15.4
million at June 30, 2005.

In the six months to June 30, 2005 funds used were $17.9 million,  reducing cash
and cash equivalents from $33.3 million in December 31, 2004 to $15.4 million at
June 30, 2005.

Net days sales  outstanding  ("DSOs") at June 30, 2005 were 13 days, an increase
from the 9 days at March 31,  2005,  and 4 days at December 31, 2004 (19 days at
June 30, 2004).  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 1 day 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 $495,000.



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  renegotiations 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.  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 whom  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,  though it is  unlikely,  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.

Consolidation of Alconbury

In accordance with the provisions of FASB  Interpretation No. 46R (FIN 46R), the
Company will reflect the  consolidation of Alconbury as long as it is considered
the "primary  beneficiary" of Alconbury's  variable interests.  The Company will
not record the gain and loss  associated  with the sale of the  properties,  nor
recognize the associated changes in depreciation,  interest,  and rent expenses,
until FIN 46R  consolidation  accounting no longer  applies.  At that time,  the
Company will record a non-cash loss of approximately $44 million for the sale of
the UK properties,  and a gain of approximately  $6 million,  amortized over the
term of the lease, for the US property.  In addition,  the Company anticipates a
net reduction in its annual  depreciation  charge of approximately  $2.7million,
offset by a net  increase of $0.5  million in interest  and rent  expenses.  The
Company  anticipates  that it will  no  longer  be the  primary  beneficiary  of
Alconbury when the $10 million subordinated promissory note has been repaid.

Exchange rate fluctuations and exchange controls

The Company operates on a worldwide 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  6% 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.

     The Company has debt denominated in USD,  whereas the Company's  functional
currency is the UK pound sterling,  which results in the Company recording other
income/loss  associated  with USD debt as a  function  of  relative  changes  in
foreign  exchange rates. No decision has been made as to which currency might be
chosen as the basis for replacement financing. The Company recognizes that there
has recently  been  volatility  in exchange  rates which could have an impact on
such  refinancing.  To manage the volatility  relating to these exposures,  from
time to time, the Company may enter into certain  derivative  transactions.  The
Company holds and issues derivative  financial  instruments for economic hedging
purposes only. In April 2005 the Company  purchased a currency hedge against the
UK pound sterling.  The call amount of the hedge was (pound)15.0 million and the
put amount was $30.0 million.  There were no derivative financial instruments in
place on June 30, 2005.

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
comprehensive  loss.  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 June 30          3 months to June 30        6 months to June 30
                                                         Average rate (1)            Average rate (1)

   2004          1.9199               1.8135                  1.8070                      1.8217

<FN>

On August 2, 2005 the noon buying rate for sterling was (pound)1.00 = $1.7695.

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 June
30, 2005:

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,  2004,  each as  filed  with the
Securities and Exchange Commission.





ITEM 3            QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's (pound)22.6 million (approximately $41.1million) non-bank loan was
sterling  denominated and did not contribute to transaction  gains and losses on
the income statement. Interest on this non-bank loan was based upon LIBOR plus a
margin and  approximated  6.677% per annum for the three  months  ended June 30,
2005 and 6.656% per annum for the six months  ended June 30,  2005.  On June 14,
2005  this   non-bank  loan  was  fully  repaid  using  the  proceeds  from  the
Sale/Leaseback transaction and cash on hand.

In the three and six months ended June 30, 2005, a 1% change in LIBOR would have
resulted  in  a  fluctuation  in  interest  expense  of  $105,000  and  $212,000
respectively.

The Company  has debt  denominated  in USD,  whereas  the  Company's  functional
currency is the UK pound sterling,  which results in the Company recording other
income/loss  associated  with USD debt as a  function  of  relative  changes  in
foreign  exchange rates. No decision has been made as to which currency might be
chosen as the basis for replacement financing. The Company recognizes that there
has recently  been  volatility  in exchange  rates which could have an impact on
such  refinancing.  To manage the volatility  relating to these exposures,  from
time to time, the Company may enter into certain  derivative  transactions.  The
Company holds and issues derivative  financial  instruments for economic hedging
purposes only. In April 2005 the Company  purchased a currency hedge against the
UK pound sterling.  The call amount of the hedge was (pound)15.0 million and the
put amount was $30.0 million.  There were no derivative financial instruments in
place on June 30, 2005.

For the three and six months  ended  June 30,  2005,  approximately  73% and 74%
respectively, of the Company's net revenues were from outside the United States.

On June 30, 2005, 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.  Unlike the
Company's  position to hedge against the debt mentioned  above, the Company does
not take any  action to hedge  against  the risk of  currency  fluctuation  with
regard to the Capital  Bonds..  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 June 30, 2005 an evaluation  was carried out,  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 the Company's  disclosure  controls and procedures were effective
as of the  quarter  ended  June 30,  2005 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
June 30, 2005 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.
