ITEM 5.  OTHER EVENTS AND REQUIRED FD DISCLOSURE.

On  May  27,  2004,  Positron  Corporation  ("Positron")  issued a press release
announcing  that  it  had  entered  into  a  series  of  agreements  with IMAGIN
Diagnostic  Centres,  Inc.  ("IMAGIN")  pursuant  to  which IMAGIN has agreed to
provide  over  the  next  seven  months an aggregate financing to Positron of $2
million.  When  the  financing  is  completed  and  if all conversion rights are
exercised,  IMAGIN  will  control  approximately  one-half  of Positron's common
stock.  In  the  first  stage of the financing, IMAGIN has agreed to purchase an
aggregate  of  $700,000 face amount of Positron's 10% convertible secured notes,
$400,000  of  which  were  purchased  on May 27, 2004. The notes are due May 21,
2006.

Pursuant  to  the  terms  of  the  agreements,  Positron has granted to IMAGIN a
security  interest  in all of its assets to secure the payment of the notes. The
notes are initially convertible into a new Series C Preferred Stock that in turn
is  convertible  into  an  aggregate  of 35,000,000 million shares of Positron's
common  stock.

IMAGIN also agreed, in a second stage of the financing, to purchase an aggregate
of  $1.3  million of Positron's 10% secured convertible notes. IMAGIN has agreed
to  purchase  the  notes over a six and a half month period, commencing July 15,
2004.  The  notes  are initially convertible into a new Series D Preferred Stock
that,  in  turn,  is  convertible into 55,000,000 shares of the company's common
stock.

Full  convertibility  of  the  Series  C  and  Series  D  Preferred  shares into
Positron's  common  stock  will  require  an amendment to Positron's Articles of
Incorporation  which  must  be approved by Positron's shareholders. Positron has
agreed  to  promptly  seek  such  approval.

In  connection  with  the  financing,  IMAGIN  has  entered  into  an additional
agreement  to  purchase  an  aggregate of 10 PET scanners at a purchase price of
$1.3  million  each. IMAGIN's obligations to purchase these scanners are subject
to  obtaining  all  necessary  Canadian regulatory approvals for the importation
into  and use of the equipment in Canada. The purchase is also subject to IMAGIN
obtaining  the  necessary  financing.  There  is no certainty that the necessary
regulatory  approvals  can  or  will  be obtained or that IMAGIN will be able to
obtain  the  necessary  financing.

Also  in connection with the transaction, Patrick G. Rooney, Chairman and CEO of
Cipher  Holding  Corporation  and  Jack  McConnaughy,  Chairman  and CEO of JEMC
Corporation,  a  private  investment firm and former Chairman and CEO of Peabody
International  Corporation,  will  be  joining  Positron's  board  of directors.
Positron  has  agreed  to  pay  a  $200,000 fee to IMAGIN upon completion of the
financing.
