WEST LAFAYETTE,  IND.--JUNE 20, 2002--BIOANALYTICAL  SYSTEMS, INC. (NASDAQ:BASI)
ANNOUNCED   TODAY  THAT  IT  HAS  SIGNED  A  DEFINITIVE   AGREEMENT  TO  ACQUIRE
PHARMAKINETICS  LABORATORIES,  INC. (OTCBB:PKLB) IN BALTIMORE,  MARYLAND, AND IT
HAS  REACHED  AN  AGREEMENT  IN  PRINCIPLE  TO  ACQUIRE LC  RESOURCES,  INC.,  A
PRIVATELY-HELD COMPANY BASED IN WALNUT CREEK, CALIFORNIA.

The  acquisitions  will  enable the  Company to broaden  its  contract  research
services  technology  base and add new strategic  locations  that will place the
Company closer to leading pharmaceutical developers across the United States.

The   PharmaKinetics   agreement   provides  for  a  merger  of   PharmaKinetics
Laboratories,  Inc.  (PKLB)  with a  newly-formed  subsidiary  of  Bioanalytical
Systems (BAS).  Shares of PKLB common stock outstanding at the effective time of
the merger will be  converted  into shares of BAS common  stock at a rate of one
BAS share for each 12 PKLB shares; shares of PKLB Series A convertible preferred
stock will be converted into 6% subordinated convertible promissory notes issued
by BAS in an aggregate principal amount of $5 million; and shares of PKLB Series
B convertible  preferred stock will be converted into shares of BAS common stock
at the same ratio as shares of PKLB common stock. The promissory notes issued in
the merger mature on January 1, 2008,  will not bear interest for the first year
following  the  effective  time of the merger,  and will be  convertible  at the
option of the holder  into BAS  common  stock at a  conversion  price of $16 per
share.  The  transaction  is subject to approval by the BAS board and  customary
closing conditions, including registration of the BAS securities to be issued in
the merger and the  approval  of PKLB's  shareholders.  The merger is  currently
expected to close prior to the end of BAS' current fiscal year.  Holders of more
than 85% of the Class A Convertible  Preferred Stock of PKLB have agreed to vote
those shares in favor of the merger.

LC  Resources  would  be  acquired  through  the  purchase  by BAS of all of the
outstanding  shares of LC Resources,  Inc.  (LCR) for $2.5  million,  subject to
adjustment for certain  changes in net tangible  assets of LCR prior to closing.
BAS would pay cash of $250,000 at closing,  and the  remainder  of the  purchase
price would be in the form of promissory  notes  maturing on October 1, 2007 and
bearing  interest at a rate of 10% per annum. The holders of the notes will have
the  option  to  require  BAS to  repay up to 20% of the  outstanding  principal
balance of the notes on each October 1 prior to maturity,  commencing October 1,
2003.  The  agreement  in  principle  also   contemplates  that  certain  assets
comprising  separate lines of business of LCR will be sold to an unrelated third
party  contemporaneously  with  the  closing  of the  purchase  by BAS,  and the
proceeds  of that sale would be  distributed  to the LCR  shareholders.  The LCR
transaction is subject to BAS ability to obtain  financing for the  transaction,
the  subsequent  operation of LCR's  business on terms  acceptable to it and the
receipt of certain  required  consents  and  approvals.  The  parties  currently
anticipate  that closing of the LCR  transaction  will occur prior to the end of
BAS' current fiscal year.

PharmaKinetics is an established  provider of bioanalytical  contract  services,
Phase I/IIa clinical trials and later-stage  clinical  trials  management.  "The
integration of PharmaKinetics will bring to BAS a successful management team and
expanded  bioanalytical  and Phase I service  capabilities,  as well as a strong
customer and revenue base," said Peter T. Kissinger,  BAS Chairman and CEO. "The
companies'  businesses are highly complementary and support the BAS growth plan.
In  addition,  Baltimore  is key to  unparalleled  access to the East Coast drug
development corridor and its outstanding biomedical community."

According to Dr. James  Wilkinson,  PharmaKinetics  President and CEO, "There is
amazing  potential for this  marriage.  Common  cultures and  commitment of both
firms to client  satisfaction and regulatory  excellence make this a very strong
union."

LC Resources  has an expert team that  maintains a high profile in  bioanalysis,
assisting many large and small drug  developers  with both  analytical  contract
services and training.  Their  bioanalytical  laboratory in McMinnville,  Oregon
will enable BAS to expand its services and products presence on the West Coast.




Dr. Kissinger went on to say, "The BAS business model,  and our passion,  bridge
the  space  between  late  discovery  (theory)  and  Phase  II  clinical  trials
(reality),  from mice to man.  We have long  focused our  people,  products  and
laboratories  on the space that  integrates  animal  science  and  bioanalytical
science.  These acquisitions bring us highly talented bioanalytical and clinical
research teams and establish BAS in early phase clinical research."

Kissinger  concluded,  "With the anticipated  completion of both acquisitions by
the end of BAS' current  fiscal year, we will gain an increased  presence in key
geographic  markets for the contract  services  industry  throughout  the United
States.  The additional  sites will  complement our core sites in West Lafayette
and  Warwickshire,  UK, and support  our  commitment  as a global  bioanalytical
resource  for drug  developers.  By placing us closer to leading  pharmaceutical
companies  and expanding our core  competency  in  pre-clinical  and early stage
clinical research,  the acquisitions will enable more pronounced  expansion into
large pharma, biotech and generic firms."
