ITEM 2.  ACQUISITIONS OR DISPOSITIONS OF ASSETS.

CANCELLATION  OF $2,000,000  NOTE AND OTHER  OBLIGATIONS IN EXCHANGE FOR SALE OF
CARDIAC PET SOFTWARE TO GENERAL ELECTRIC COMPANY.

       On June 29, 2003 Positron  Corporation  (the  "Company")  entered into an
agreement with General Electric  Company,  acting through its GE Medical Systems
Division  ("GE"),  pursuant to which GE agreed to surrender for  cancellation  a
$2,000,000  note,  including  all  accrued  interest,  9,000,000  shares  of the
Company's  common stock and a warrant  exercisable  for 6,000,000  shares of the
Company's  common  stock in exchange  for the Company  selling to GE cardiac PET
software.  The  canceled  note and  surrendered  common  stock and warrant  were
originally issued to Imatron Inc. and were later acquired by GE when it acquired
Imatron  Inc. in 2001.  In  connection  with the sale of assets,  GE granted the
Company a worldwide, perpetual,  non-exclusive,  royalty-free license to use the
transferred  cardiac Pet  software.  GE and the Company  entered into a services
agreement  whereby GE will pay the Company to provide  support to transition the
software to GE. The amount of the consideration  received by the Company for the
sale of the technology was determined through  negotiations  between the parties
and approved by the Company's  board of  directors.  A copy of the press release
announcing  the  transaction  is attached as Exhibit  99.1 to this Report and is
incorporated herein by reference.

DESCRIPTION OF RELATIONSHIP BETWEEN THE COMPANY AND IMATRON INC.

       In May 1998,  the Company  entered  into an  agreement  with Imatron Inc.
Pursuant to the agreement,  Imatron  acquired  9,000,000 shares of the Company's
common  stock on  January  22,  1999,  representing  at that  time,  a  majority
ownership of the outstanding  common stock of the Company on a fully-diluted and
as-if-converted   basis,   excluding   out-of-the-money   warrants  and  options
determined  at that time.  In exchange,  the Company  received  from Imatron (a)
nominal  cash;  (b) an  immediate  loan of up to $500,000 in working  capital to
assist  the  Company in  meeting  then  current  financial  obligations;  (c) an
agreement  that  Imatron  would  undertake  all  reasonable  efforts to have its
affiliate,  Imatron Japan, Inc. assist the Company in the sale of 10 POSICAM(TM)
systems over the next three  years;  (d) an  agreement  that Imatron  would help
facilitate the  recapitalization of the Company to support its re-entry into the
medical  imaging  market by using its best  efforts  to arrange  for  additional
third-party equity financing for the Company over an eighteen-month period in an
aggregate  amount of not less than  $8,000,000;  and (e) a new  management  team
selected by Imatron. During the year ended December 31, 2001, Imatron loaned the
Company  $2,000,000.  On December  19,  2001,  Imatron  was  acquired by General
Electric  Company.  General Electric Company is a competing  manufacturer of PET
imaging systems.
