Item 5.  Other Events.

     On June 20,  2002,  Bioanalytical  Systems,  Inc.,  an Indiana  corporation
("BAS"),  PI  Acquisition  Corp.,  a  Maryland  corporation  and a wholly  owned
subsidiary of BAS  ("Acquisition"),  and  PharmaKinetics  Laboratories,  Inc., a
Maryland  corporation ("PKLB") entered into an Agreement and Plan of Merger (the
"Merger  Agreement") which provides for, subject to the terms and conditions set
forth therein, the merger of PKLB and Acquisition (the "Merger").

     As of the  effective  time  of the  Merger,  shares  of PKLB  common  stock
outstanding  will be converted  into shares of BAS common stock at a rate of one
BAS  shares  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 $5,000,000;  and shares
of PKLB Series B convertible  preferred  stock will be converted  into shares of
BAS  common  stock at the same  ratios  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 $16.00 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 PKLB's Class A  convertible  preferred
stock have agreed to vote those shares in favor of the merger.

     A copy of the Merger  Agreement  is  attached  hereto as Exhibit  2.1.  The
foregoing description is qualified in its entirety by reference to the full text
of the Merger  Agreement  set forth in Exhibit  2.1. A copy of the  Exhibits and
Schedules  to the Merger  Agreement  will be  provided  to the  Commission  upon
request.  A joint  press  release  announcing  the Merger was issued on June 20,
2002.  A copy of the text of the press  release  is  attached  hereto as Exhibit
99.1.
