On June 14, 2005, Life Sciences  Research,  Inc. and subsidiaries  (collectively
"LSR"  or  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 "
Transaction").  Alconbury  is a newly  formed  company  wholly  owned  by  LSR's
Chairman and CEO, Andrew Baker.  Mr. Baker currently is the beneficial  owner of
approximately  17.9%  of the  Company's  outstanding  shares  of  common  stock.
Virtually  all of such shares have been pledged by Mr. Baker as security for the
funds borrowed by Alconbury to pay the  consideration  for the Transaction.  The
total  consideration  paid by Alconbury for the three properties is $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.

As a part of the 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  $4,900,000
(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.  The foregoing summary is subject to, and qualified in its entirety
by, the terms of the purchase and sale agreements, the leases and the promissory
note,  attached hereto as Exhibits 2.1, 2.2, 2.3, 10.1, 10.2, 10.3 and 10.4, the
terms of which are incorporated herein by reference.

Since the Transaction is with a related party (Mr. Baker, the Company'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
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 Transaction with Alconbury.  The total consideration
paid was based on an assessment and review of the levels of  consideration  that
were  proposed  to be paid by  independent  third  party  bidders  over the past
several  years  for  sale/leaseback  transactions  of  the  Company's  operating
facilities in transactions  that were proposed and negotiated but not ultimately
consummated.  The Committee  also obtained  appraisals  of the  facilities  from
independent real estate appraisal firms.

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

On June 14, 2005, the Company issued a press release  regarding the Transaction.
The  Company's  press  release is attached as Exhibit  99.1 and is  incorporated
herein by reference.
