                            STOCK PURCHASE AGREEMENT


     THIS  STOCK  PURCHASE  AGREEMENT  ("Agreement")  is made as of the date set
forth on the signature page hereof  ("Signature  Page") by and between  POSITRON
CORPORATION,  a Texas corporation with principal offices located at 1304 Langham
Creek Drive,  Houston,  Texas 77084  ("Seller") and the purchaser whose name and
authorized signature appear on the Signature Page (the "Purchaser").

     WHEREAS,  Seller has  authorized the issuance and sale of certain shares of
its Common Stock (the "Common Stock") in exchange for certain consideration; and

     WHEREAS,  Purchaser  desires to  purchase  and  Seller  desires to sell the
Shares on the terms and conditions set forth herein.

     NOW,  THEREFORE,  in  consideration of the mutual covenants and agreements,
the Seller and Purchaser hereby agree as follows:

                                    AGREEMENT

     1. Purchase and Sale of Shares. Seller agrees to sell to Purchaser and upon
the basis of the  representations  and warranties,  and subject to the terms and
conditions,  set forth in this  Agreement,  Purchaser  agrees to  purchase  that
number of Shares set forth  opposite its name on the Signature  Page  ("Shares")
for an Aggregate Purchase Price equal to the number of Shares times US$0.30.

     2.  Closing.  The closing of the  purchase  and sale of Shares  pursuant to
Section 1 hereof  shall take place at the offices of Seller set forth in Section
12 below on July 16, 1999 The Aggregate  Purchase  Price shall be transmitted by
Purchaser  by wire  transfer  into an Escrow  Account  as set forth in Exhibit A
hereto where such funds shall be held until Closing. In the event the conditions
set forth in Section 6 have not been satisfied or waived by July 16, 999, at the
option of either  party all funds shall be returned to Purchaser  together  with
the interest  thereon and this  Agreement  shall  thereafter be without  further
force or effect.  Until Closing all funds  deposited into escrow shall belong to
and be the property of Purchaser.

     At the Closing, Seller will deliver to Purchaser certificates  representing
the  Shares.   Delivery  of  such  certificates  shall  be  in  accordance  with
Purchaser's instructions.

     3.  Restriction on Transfer of Securities.

          3.1  Restrictions.  The Shares are transferable only pursuant to (a) a
public  offering  registered  under the  Securities Act of 1933, as amended (the
"Securities  Act"),  (b) Rule 144 (or any similar  rule then in effect)  adopted
under the  Securities  Act,  if such rule is  available,  and (c) subject to the
conditions  elsewhere  specified in this Section 3, any other legally  available
means of transfer.

          3.2 Legend. Each certificate representing Shares will be endorsed with
the following  legend:  "The securities  evidenced hereby may not be transferred
without  (i) the  opinion  of  counsel  satisfactory  to the  Company  that such
transfer may be lawfully made without  registration  under the Securities Act of
1933 and all applicable state securities laws or (ii) such registration."

          3.3 Stop Transfer  Order.  A stop transfer  order shall be placed with
the Seller's  transfer  agent  preventing  transfer of any of the Shares pending
compliance with the conditions set forth in any such legend.

          3.4  Removal  of Legend.  Any  legend  endorsed  on a  certificate  or
instrument  evidencing  the Shares  shall be removed,  and Seller  shall issue a
certificate or instrument without such legend to the holder of such security (a)
if such  security  is being  disposed  of  pursuant  to  registration  under the
Securities  Act and any  applicable  state acts or  pursuant  to Rule 144 or any
similar  rule then in effect,  or (b) if such  holder  provides  Seller  with an
opinion  of counsel  satisfactory  to it to the  effect  that a sale,  transfer,
assignment, offer, pledge or distribution for value of such security may be made
without  registration  and that  such  legend is not  required  to  satisfy  the
applicable exemption from registration.

     4. Representations and Warranties by Seller. Seller represents and warrants
to Purchaser that:

          4.1  Organization,  Standing,  Power.  Seller  is a  corporation  duly
organized,  validly existing and in good standing under the laws of the State of
Texas and has the requisite  corporate power and authority to own its properties
and to  carry  on its  business  in all  material  respects  as it is now  being
conducted.  Seller has, or at the Closing  will have,  the  requisite  corporate
power  and  authority  to  issue  the  Shares,  and  to  otherwise  perform  its
obligations under this Agreement.

          4.2  Qualification.  Seller is duly qualified or licensed as a foreign
corporation  in good  standing  in each  jurisdiction  wherein the nature of its
activities  or of its  properties  owned or leased makes such  qualification  or
licensing  necessary  and failure to be so  qualified  or licensed  would have a
material adverse impact on its business.

          4.3  Compliance  with  Applicable  Laws  and  Other  Instruments.  The
business  and  operations  of  Seller  have  been  and are  being  conducted  in
accordance with all applicable  laws,  rules and regulations of all governmental
authorities.  Neither the execution nor delivery of, nor the  performance  of or
compliance  with,  this  Agreement  nor  the  consummation  of the  transactions
contemplated  hereby will conflict with or, with or without the giving of notice
or passage of time,  result in any breach of, or constitute a default under,  or
result in the imposition of any lien or  encumbrance  upon any asset or property
of  Seller  pursuant  to,  any  applicable  law,  administrative  regulation  or
judgment,  order or decree of any court or  governmental  body, any agreement or
other  instrument  to  which  Seller  is a party  or by  which  it or any of its
properties,  assets or rights is bound or  affected,  and will not  violate  the
Articles of Incorporation or Bylaws of Seller. Seller is not in violation of its
Articles of Incorporation or its Bylaws.

          4.4 Common Stock. The Common, when issued and paid for pursuant to the
terms  of  this  Agreement,   will  be  duly  authorized,   validly  issued  and
outstanding, fully paid, nonassessable and free and clear of all pledges, liens,
encumbrances and restrictions.

     5.  Representations and Warranties of Purchaser.  Purchaser  represents and
warrants that:

          5.1 Investment  Intent.  The Shares being acquired hereunder are being
purchased for Purchaser's own account and not with the view to, or for resale in
connection  with, any distribution or public offering thereof within the meaning
of the  Securities  Act.  Purchaser  understands  that the Shares  have not been
registered  under the Securities  Act or any applicable  state laws by reason of
their  issuance  or  contemplated  issuance  in a  transaction  exempt  from the
registration and prospectus delivery requirements of the Securities Act and such
laws  and that the  reliance  of  Seller  and  others  upon  this  exemption  is
predicated  in part upon this  representation  and warranty.  Purchaser  further
understands  that the  Shares  may not be  transferred  or  resold  without  (a)
registration  under the Securities Act and any applicable  state securities laws
or (b) an exemption from the  requirements  of the Securities Act and applicable
state securities laws.

          5.2  Accredited  Investor.  The place in which  Purchaser's  principal
office or residence is located is set forth in Purchaser's  address as set forth
in this  Agreement.  Purchaser  qualifies as an accredited  investor  within the
meaning of Rule 501 under the Securities  Act.  Purchaser has such knowledge and
experience  in  financial  and  business  matters  that  Purchaser is capable of
evaluating  the  merits  and risks of the  investment  to be made  hereunder  by
Purchaser.

          5.3 Acts and  Proceedings.  This Agreement has been duly authorized by
all  necessary  action  on the part of  Purchaser,  has been duly  executed  and
delivered by Purchaser,  and is a valid and binding  agreement  upon the part of
Purchaser.

          5.4 No Brokers or Finders.  No person, firm or corporation has or will
have,  as a result of any act or omission by Purchaser,  any right,  interest or
valid claim against Seller for any  commission,  fee or other  compensation as a
finder  or  broker,  or  in  any  similar  capacity,   in  connection  with  the
transactions  contemplated by this Agreement.  Purchaser will indemnify and hold
Seller  harmless  against  any  and  all  liability  with  respect  to any  such
commission,  fee or other  compensation which may be payable or determined to be
payable  as a  result  of the  actions  of  Purchaser  in  connection  with  the
transactions contemplated by this Agreement.

     6. Conditions of Purchaser's Obligation. Purchaser's obligation to purchase
and pay for the Shares on the Closing Date is subject to the  fulfillment  prior
to or on the Closing Date of the conditions  set forth below.  In the event that
any such condition is not satisfied to Purchaser's satisfaction,  then Purchaser
shall not be  obligated  to proceed with the purchase of such Shares nor further
with any of its obligations pursuant to this Agreement.

this  Agreement  shall be true in all  material  respects as of the Closing Date
with the same effect as though made on and as of the Closing Date.

complied in all material respects with all agreements or conditions  required by
this  Agreement  to be performed  and complied  with by it prior to or as of the

qualifications, permits and approvals required under applicable state securities
laws for the lawful  execution  and  delivery of this  Agreement  and the offer,
sale, issuance and delivery of the Shares shall have been obtained.

actions taken in connection with the  transactions  contemplated  hereby and all
certificates,  opinions, agreements,  instruments and documents mentioned herein
or incident to any such transaction  shall be satisfactory in form and substance
to Purchaser and its counsel.

Common  Stock to  Purchaser  on the Closing  Date is subject to the  fulfillment

          8.1  Corporate   Existence.   Seller  will  maintain  and  cause  each
Subsidiary (as hereinafter  defined) to maintain its corporate existence in good
standing  and comply  with all  applicable  laws and  regulations  of the United
States or of any state or states thereof or of any political subdivision thereof
and of any  governmental  authority  where  failure  to so comply  would  have a
material adverse impact on Seller or its business or operations.

          8.2 Books of Account and Reserves. Seller will, and will cause each of
its  Subsidiaries  to, keep books of record and account in which full,  true and
correct entries are made of all of its and their respective  dealings,  business
and affairs, in accordance with generally accepted accounting principles. Seller
will  employ  certified  public  accountants  selected  by  the  Board  who  are
"independent" within the meaning of the accounting regulations of the Commission
and will have annual audits made by such independent  public  accountants in the
course of which such  accountants  shall make such  examinations,  in accordance
with generally  accepted  auditing  standards,  as will enable them to give such
reports or opinions with respect to the  financial  statements of Seller and its
Subsidiaries  that will satisfy the  requirements of the Commission in effect at
such time with respect to certificates and opinions of accountants.

          8.3 Furnishing of Financial  Statements and  Information.  Seller will
deliver to Purchaser:

               (a) as soon as practicable, but in any event within 45 days after
the close of each quarterly  period,  unaudited  consolidated  balance sheets of
Seller and its  Subsidiaries  as of the end of such  period,  together  with the
related  consolidated  statements of  operations  and cash flow for such period,
setting  forth the budgeted  figures for such period  prepared and  submitted in
connection with Seller's  annual  business plan and in comparative  form figures
for the  corresponding  quarterly  period of the previous  fiscal  year,  all in
reasonable detail and certified by an authorized  accounting  officer of Seller,
subject to year-end adjustments;

               (b) as soon as practicable, but in any event within 90 days after
the end of each fiscal  year,  a  consolidated  balance  sheet of Seller and its
Subsidiaries,  as of the end of such  fiscal  year,  together  with the  related
consolidated  statements of operations,  shareholders'  equity and cash flow for
such fiscal year,  setting  forth in  comparative  form figures for the previous
fiscal year, all in reasonable detail and duly certified by Seller's independent
public  accountants,  which  accountants  shall  have given  Seller an  opinion,
unqualified as to the scope of the audit, regarding such statements;

               (c)  with  reasonable  promptness,   such  other  financial  data
relating to the  business,  affairs and  financial  condition  of Seller and any
Subsidiaries  as is available to Seller and as from time to time  Purchaser  may
reasonably request; and

               (d) at least 20 days prior to the earlier of (i) the execution of
any agreement  relating to any merger or  consolidation  of Seller or any of its
Subsidiaries  with  another  corporation,  or a plan of exchange  involving  the
outstanding  capital  stock of Seller or any of its  Subsidiaries,  or the sale,
transfer  or other  disposition  of all or  substantially  all of the  property,
assets or business of Seller or any of its Subsidiaries to another  corporation,
or (ii) the holding of any meeting of the shareholders of Seller for the purpose
of approving  such action,  written  notice of the terms and  conditions of such
proposed  merger,  consolidation,  plan of  exchange,  sale,  transfer  or other
disposition.

     9. Registration of Stock.

          9.1 Rights to  Registration.  The  Company  shall file with the SEC as
promptly as practicable and thereafter shall use its best efforts to cause to be
declared  effective  within  ninety  (90)  days  from the date of the  Closing a
"shelf" registration  statement on the appropriate form under the Securities Act
providing for the registration of, and the sale on a continuous or delayed basis
by the holders of, all of the Shares,  pursuant to Rule 415 or any similar  rule
that may be adopted by the SEC (the "Shelf Registration Statement"). The Company
shall use its best efforts to keep the Shelf Registration Statement continuously
effective in order to permit the prospectus forming part thereof to be usable by
Purchasers for a period ending on the earlier of (i) (x) the second  anniversary
of the Closing,  (y) the  expiration  of the period  following the Closing after
which Rule 144(k) under the Securities  Act becomes  available to the Purchasers
or (z) in the  event  the  Company  has at any  time  suspended  the  use of the
prospectus  contained  in the  Shelf  Registration  Statement  pursuant  to this
paragraph, the date beyond the earlier of the periods referred to in clauses (x)
and (y) that reflects an  additional  period of days equal to the number of days
during all of the periods from and  including the dates the Company gives notice
of such  suspension  pursuant to this  paragraph to and  including the date when
holders of Shares  receive an amended or  supplemented  prospectus  necessary to
permit  resales  of  Shares  under the Shelf  Registration  Statement  or to and
including the date on which the Company  gives a resumption  notice or (ii) such
time as all of the Shares covered by the Shelf Registration  Statement have been
sold  pursuant to the Shelf  Registration  Statement or pursuant to Rule 144 (in
any such case, such period being called the "Shelf  Registration  Period").  The
Company  shall be  deemed  not to have used its best  efforts  to keep the Shelf
Registration  Statement  effective during the requisite period if it voluntarily
takes any action  that would  result in holders of Shares  covered  thereby  not
being able to offer and sell Shares during that period,  unless such action,  in
the opinion of the Company after  consulting with legal counsel,  is required by
applicable law.  Notwithstanding  any other provisions  hereof, the Company will
ensure that (i) any Shelf  Registration  Statement and any amendment thereto and
any prospectus  forming part thereof and any supplement  thereto complies in all
material  respects  with  the  Securities  Act and  the  rules  and  regulations
thereunder, (ii) any Shelf Registration Statement and any amendment thereto does
not, when it becomes  effective,  contain an untrue statement of a material fact
or omit to state a material  fact  required to be stated  herein or necessary to
make the statements therein not misleading and (iii) any prospectus forming part
of any Shelf Registration Statement,  and any supplement to such prospectus does
not include an untrue  statement of a material  fact or omit to state a material
fact  necessary  in order to make the  statements  therein,  in the light of the
circumstances under which they were made, not misleading.

          9.2 Other  Registrations.  If at any time during the period commencing
six (6) months  after the  Closing of the  purchase  and sale  pursuant  to this
Agreement  and ending ten (10)  years  thereafter,  Seller  shall  determine  to
register under the Securities Act of 1933, as amended, any shares of Stock to be
offered for cash by it or others,  pursuant to a registration  statement on Form
S-1 (or its  equivalent),  Seller  will (i)  promptly  give  written  notice  to
Purchaser  of its  intention  to file such  registration  statement  and (ii) at
Seller's expense (which shall include, without limitation,  all registration and
filing  fees,   printing  expenses,   fees  and  disbursements  of  counsel  and
independent accountants for Seller, and fees and expenses incident to compliance
with state  securities  law,  but shall not include  fees and  disbursements  of
counsel for Purchaser)  include among the securities covered by the registration
statement  such  portions  of the  Shares  then  held by  Purchaser  as shall be
specified in a written  request to Seller within thirty (30) days after the date
on which  Seller gave the notice  described  in (i) above.  Upon receipt of such
written  request  and of the  shares  of Stock  specified  in the  request  (any
shareholder  requesting   registration  being  individually  called  a  "Selling
Shareholder"),  Seller shall (i) use its  reasonable  best efforts to effect the
registration, qualification or compliance of the Shares under the Securities Act
and under any other applicable federal law and any applicable securities or blue
sky laws of  jurisdictions  within the United States;  (ii) furnish each Selling
Shareholder   such  number  of  copies  of  the  prospectus   contained  in  the
registration  statement  filed under the Securities  Act (including  preliminary
prospectus) in conformity with the  requirements of the Securities Act, and such
other documents as the Selling  Shareholder  may reasonably  request in order to
facilitate the disposition of the Stock covered by the  registration  statement;
and (iii)  notify  each  Selling  Shareholders,  at any time  when a  prospectus
relating to the Stock covered by such  registration  statement is required to be
delivered under the Securities Act, of the happening of any event as a result of
which the prospectus forming a part of such registration  statement,  as then in
effect,  includes an untrue  statement of a material  fact or omits to state any
material fact required to be stated  therein or necessary to make the statements
therein not  misleading,  and (iv) at the  request of the  Selling  Shareholders
prepare and furnish to the Selling  Shareholders any reasonable number of copies
of any  supplement  to or  amendment of such  prospectus  as may be necessary so
that, as thereafter  delivered to purchasers of the Stock, such prospectus shall
not include an untrue  statement of a material  fact or omit to state a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading.

          9.3  Registration  of  Underwritten   Offering.  If  the  offering  of
securities to be registered by Seller is underwritten,  each Selling shareholder
shall sell the Stock to or through the  underwriter(s)  of the securities  being
registered for the account of Seller or others upon the same terms applicable to
Seller or others, and if the managing  underwriter(s)  reasonably determine that
all or any  portion  of the  shares of Stock  held by the  Selling  Shareholders
should not be  included  in the  registration  statement,  then  notwithstanding
anything  to  the  contrary  in  this  Section,   the   determination   of  such
underwriter(s)   shall  be   conclusive;   provided,   however,   that  if  such
underwriter(s)  determine  that  some but not all of the  Stock  of the  Selling
Shareholders  shall be included  in the  registration  statement,  the number of
shares  of  Stock  owned  by each  Selling  Shareholder  to be  included  in the
registration  statement will be  proportionately  reduced in accordance with the
respective written requests given as provided above.

          9.4  Indemnification.  In the event that Shares purchased  pursuant to
this  Agreement are included in a registration  statement  under this Section 9,
Seller will indemnify and hold harmless each Selling  Shareholder and each other
person, if any, who controls such Selling  shareholder within the meaning of the
Securities Act,  against any losses,  claims,  damages or liabilities,  joint or
several,  to which such Selling  Shareholder  or  controlling  person may become
subject under the Securities Act or otherwise,  insofar as such losses,  claims,
damages or  liabilities  (or actions in respect  thereof) arise out of are based
upon any untrue  statement or alleged  untrue  statement  of any  material  fact
contained, on the effective date thereof, in any registration statement pursuant
to which the Shares were  registered  under the Securities  Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto,  or arise out of or are based upon the omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the  statements  therein not  misleading,  or arise out of or are based upon the
failure by Seller to file any amendment or supplement  thereto that was required
to  be  filed  under  the  Securities  Act,  and  will  reimburse  such  Selling
Shareholder and each such controlling person for any legal or any other expenses
reasonably  incurred by them in connection with  investigating  or defending any
such loss, claim,  damage,  liability or action.  Notwithstanding the foregoing,
Seller  will not be liable in any such case to the  extent  that any such  loss,
claim,  damage,  or liability arises out of or is based upon an untrue statement
or omission made in such registration statement,  preliminary prospectus,  final
prospectus or amendment or  supplement  in reliance upon and in conformity  with
written  information  furnished to Seller through an instrument duly executed by
or on behalf of any Selling Shareholder  specifically for use in the preparation
of such registration  statement,  preliminary prospectus,  final prospectus,  or
amendment or supplement.

     It shall be a condition  precedent to the  obligation of Seller to take any
action  pursuant to this Section that seller shall have received an  undertaking
satisfactory to it from each Selling  Shareholder to indemnify and hold harmless
Seller (in the same manner and to the same extent as set forth in this Section),
each  director  of  Seller,  each  officer  who  shall  sign  such  registration
statement,  and any  persons  who  control  Seller  within  the  meaning  of the
Securities Act, with respect to any statement or omission from such registration
statement, preliminary prospectus, or any final prospectus contained therein, or
any amendment or supplement  thereto,  if such statement or omission was made in
reliance upon and in  conformity  with written  information  furnished to Seller
through an instrument duly executed by the indemnifying  party  specifically for
use in the preparation of such registration  statement,  preliminary prospectus,
final prospectus, or amendment or supplement.

     Promptly  following  receipt  by an  indemnified  party  of  notice  of the
commencement  of any action  involving a claim referred to above in this Section
9.3, such  indemnified  party will, if a claim in respect  thereof is to be made
against  an  indemnifying  party,  give  written  notice  to the  latter  of the
commencement  of such  action.  In case any such  action is  brought  against an
indemnified party, the indemnifying party will be entitled to participate in and
to  assume  the  defense  thereof,  jointly  with any other  indemnifying  party
similarly  notified,  to the extent that it may wish,  with  counsel  reasonably
satisfactory to such  indemnified  party, and after notice from the indemnifying
party to such  indemnified  party of its election to assume the defense thereof,
the  indemnifying  party  will not be liable to such  indemnified  party for any
legal or other expenses  subsequently  incurred by the latter in connection with
the defense thereof.

          9.5 Binding  Provisions.  The  provisions  of this  Section 9 shall be
binding on the successors of Seller. No Shareholder may assign the provisions of
this  Section  9 or all or any  part  of its  or  their  rights  or  obligations
hereunder,  except that in the event of a merger or  consolidation  in which the
Seller is not the survivor,  the Seller shall assign and transfer, and successor
shall assume, the provisions of this Section 9.

          9.6  Conflicts.  To the  extent  that  Seller's  compliance  with  the
obligations  set forth in Sections 9.1 through 9.5 above would  conflict with or
otherwise  cause a breach of or default  under any of its  existing  obligations
pursuant to any agreements to which it currently is a party, Seller's failure to
comply with those obligations shall not be deemed a breach of this Agreement.

     10.  Remedies  Cumulative,  and not Waived.  (a) No right,  power or remedy
conferred  upon any party  shall be  exclusive,  and each such  right,  power or
remedy  shall be  cumulative  and in  addition to every  other  right,  power or
remedy,  whether  conferred  hereby or by any such  security or now or hereafter
available  at law or in  equity or by  statute  or  otherwise.  (b) No course of
dealing  between the parties or the holder of any Shares  purchased  pursuant to
this Agreement,  and no delay in exercising any right, power or remedy conferred
hereby or by any such security or now or hereafter  existing at law or in equity
or by statute or otherwise,  shall operate as a waiver of or otherwise prejudice
any such right, power or remedy;  provided,  however, that this Section 10 shall
not be  construed  or applied so as to negate the  provisions  and intent of any
statute which is otherwise applicable.

     11. Changes.  Waivers. etc. Neither this Agreement nor any provision hereof
may be changed, waived, discharged or terminated orally, but only by a statement
in writing signed by the party against which enforcement of the change,  waiver,
discharge or termination is sought.

                              POSITRON CORPORATION

                          COMMON STOCK PURCHASE WARRANT
                  TO PURCHASE _________ SHARES OF COMMON STOCK
                             OF POSITRON CORPORATION

                          This Warrant Expires ________


Warrant No. 99-__                                            ____________ Shares


          THIS CERTIFIES  that,  subject to the terms and conditions  herein set
forth in this warrant,  [ ] (the "Holder") is entitled to purchase from Positron
Corporation,  a Texas corporation ("Company"),  at any time or from time to time
during the  Exercise  Period  (defined  in Section 12 below) and  subject to the
provisions  regarding  Exercise of Warrant (as set forth in Section 6 below) the
number of fully paid and  non-assessable  shares of common  stock of the Company
(the  "Shares")  as  provided  herein  upon  surrender  of this  Warrant  at the
principal  office of the  Company,  and, at the  election  of the  Holder,  upon
payment of the purchase price at said office in cash or by cashier's check or by
the wire transfer of funds in a dollar amount equal to the purchase price of the
Shares for which the consideration is being given.

     This Warrant  shall be  exercisable  for that number of Shares as set forth
above.

     1.  Purchase  Price.  Subject to adjustment as  hereinafter  provided,  the
purchase  price of one  share of  Common  Stock  (or such  securities  as may be
substituted for one share of Common Stock pursuant to the provisions hereinafter
set forth) (the "Warrant Price") shall Thirty Cents ($0.30).

     2. Adjustment of Warrant Price and Number of Shares. The number and kind of
securities  issuable  upon the  exercise  of this  Warrant  shall be  subject to
adjustment from time to time upon the happening of certain events as follows:

          a.  Adjustment for Dividends in Stock.  If at any time on or after the
date  hereof,  the holders of the Common  Stock of the Company (or any shares of
stock or other  securities  at the time  receivable  upon the  exercise  of this
Warrant)  shall have  received,  or, on or after the  record  date fixed for the
determination of eligible  stockholders,  shall have become entitled to receive,
without  payment  therefor,  other or additional  stock of the Company by way of
dividend  (other than as provided for in Section  2(b) below),  then and in each
such case,  upon the exercise of this  Warrant,  the Holder shall be entitled to
receive,  in addition to the number of shares of Common  Stock  receivable,  and
without  payment of any additional  consideration  therefor,  the amount of such
other or  additional  stock of the Company which the Holder would receive on the
date of such  exercise  had it been the holder of record of such Common Stock on
the date  hereof and had  thereafter,  during the period from the date hereof to
and including the date of such  exercise,  retained such shares and/or all other
additional  stock  receivable  by it as  aforesaid  during such period and given
effect to all adjustments called for during such period by this Section 2.

          b.  Adjustment for Changes in Common Stock. In the event of changes in
the   outstanding   Common  Stock  of  the  Company  by  reason  of  split--ups,
recapitalizations,  reclassifications,  mergers, consolidations, combinations or
exchanges of shares, separations,  reorganizations,  liquidations,  or the like,
the number and class of shares  available under the Warrant in the aggregate and
the Warrant Price shall be correspondingly adjusted by the Board of Directors of
the Company.  The  adjustment  shall be such as will give the Holder on exercise
for the same aggregate Warrant Price the total number, class, and kind of shares
as the Holder would have owned had the Warrant been exercised prior to the event
and had the Holder continued to hold such shares until after the event requiring
adjustment.

     3. No  Fractional  Shares.  No  fractional  shares of Common  Stock will be
issued in connection with any  subscription  under this Warrant.  In lieu of any
fractional shares which would otherwise be issuable,  the Company shall pay cash
equal to the product of such fraction multiplied by the fair market value of one
share of Common Stock on the date of exercise as determined in good faith by the
Company's Board of Directors.

     4. No Stockholder  Rights. This Warrant shall not entitle its holder to any
of the rights of a stockholder of the Company prior to its exercise.

     5. Reservation of Stock. The Company  covenants that during the period this
Warrant is  exercisable,  the  Company  will  reserve  from its  authorized  and
unissued Common Stock a sufficient  number of shares to provide for the issuance
of Common Stock upon the exercise of this Warrant.  The Company  agrees that its
issuance of this Warrant shall constitute full authority to its officers who are
charged with the duty of executing  stock  certificates to execute and issue the
necessary  certificates  for shares of Common  Stock upon the  exercise  of this
Warrant.

     6. Exercise of Warrant.  Subject to the terms and conditions  hereof,  this
Warrant may be exercised by the holder  hereof then  registered  on the books of
the  Company as  follows:  750,000  shares at any time one year from the Date of
Issuance and before the  Expiration  Date;  750,000 shares at any time after one
year from the Date of  Issuance  and before the  Expiration  Date;  and  750,000
shares at any time  after two years  from the Date of  Issuance  and  before the
Expiration  Date;  750,000 shares at any time after three years from the Date of
Issuance and before the  Expiration  Date;  and 750,000 shares at any time after
four years from the Date of Issuance and before the Expiration Date.  Subject to
the  foregoing,  This Warrant may be  exercised by the Holder or its  registered
assigns,  in whole or in part and in  minimum  units of  10,000  shares,  by the
surrender of this Warrant at the principal office of the Company,  together with
the attached form of subscription duly executed,  accompanied by payment in full
of the amount of the Warrant Price in the form  described in this Warrant.  Upon
partial exercise of this Warrant, a new warrant or warrants  containing the same
date and  provisions  as this  Warrant  shall be  issued by the  Company  to the
registered holder for the number of shares of Common Stock with respect to which
this Warrant  shall not have been  exercised.  A Warrant shall be deemed to have
been  exercised  immediately  prior to the close of  business on the date of its
surrender for exercise as provided above, and the person entitled to receive the
shares of Common  Stock  issuable  upon such  exercise  shall be treated for all
purposes  as the holder of such  shares of record as of the close of business on
such date. As promptly as  practicable  on or after such date, the Company shall
issue and deliver to the person or persons  entitled  to receive  the shares,  a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable  upon such  exercise,  together  with cash in lieu of any fraction of a
share as provided above.

     7.  Certificate  of  Adjustment.  Whenever the Warrant Price is adjusted as
provided in Section 2, the Company shall  promptly  deliver to the record holder
of this Warrant a  certificate  of an officer of the Company  setting  forth the
relevant  Warrant  Price or number of shares after such  adjustment  and setting
forth a brief statement of the facts requiring such adjustment.

     8.  Compliance  With  Securities  Act. The Holder,  by  acceptance  of this
Warrant,  agrees that this  Warrant and the shares of Common  Stock to be issued
upon its exercise (or shares of any security into which such Common Stock may be
converted)  (the "Shares") are being acquired for investment and that the Holder
will not offer,  sell,  or  otherwise  dispose of this Warrant and any shares of
Common  Stock to be issued upon its  exercise  (or shares of any  security  into
which such Common Stock may be converted) except under  circumstances which will
not  result in a  violation  of the  Securities  Act of 1933,  as  amended  (the
"Securities  Act").  Upon exercise of this Warrant,  the holder hereof shall, if
requested  by the  Company,  confirm  in  writing  its  investment  purpose  and
acceptance of the restrictions on transfer of the Shares.

     9. Subdivision of Warrant.  At the request of the holder of this Warrant in
connection  with a transfer  or  exercise  of a portion of the  Warrant and upon
surrender of this  Warrant for such  purpose to the Company,  the Company at its
expense  (except for any transfer tax payable)  will issue in exchange  therefor
warrants  of like  tenor and date  representing  in the  aggregate  the right to
purchase  such number of shares of such Common Stock as shall be  designated  by
such holder at the time of such surrender; provided, however, that the Company's
obligations to subdivide  securities  under this Section shall be subject to and
conditioned  upon the compliance of any such  subdivision  with applicable state
securities laws and with the Securities Act.

     10. Loss, Theft, Destruction, or Mutilation of Warrant. Upon receipt by the
Company  of  evidence  reasonably   satisfactory  to  it  of  the  loss,  theft,
destruction,  or mutilation of this Warrant,  and in the case of loss, theft, or
destruction,  of  indemnity  or  security  reasonably  satisfactory  to  it  and
reimbursement to the Company of all reasonable  expenses  incidental thereto, in
the case of mutilation,  and upon surrender and cancellation of this Warrant the
Company  will make and  deliver a new Warrant of like tenor and dates as of such
cancellation, in lieu of this Warrant.

     11. Miscellaneous.  This Warrant shall be governed by the laws of the State
of Texas.  The  headings in this  Warrant are for  purposes of  convenience  and
reference  only,  and shall not be deemed to  constitute a part of this Warrant.
Neither this Warrant nor any term included may be changed,  waived,  discharged,
or terminated  orally but only by an instrument in writing signed by the Company
and the Holder.  All notices  and other  communications  from the Company to the
Holder  shall  be by  telecopy  or  expedited  courier  service  to the  address
furnished to the Company in writing by the last holder of this Warrant who shall
have  furnished  an address to the  Company in  writing.  This  Warrant has been

For Immediate Release


             Positron Corporation and Imatron Announce Completion of
              $12.7 Million Private Equity Financing for Positron


                   Financing to Fund Positron's Re-launch into
                             PET Imaging Marketplace


Houston,  TX, August 18, 1999 - Positron  Corporation (OTC BB: POSC) and Imatron
Inc.  (Nasdaq:  IMAT) of So. San Francisco  announced  today the completion of a
private placement of 42,166,664 shares of Positron's common stock for a total of
$12.7  million.  In  connection  with this private  placement,  Positron  issued
21,460,000 five-year warrants. Proceeds will be used to pay debt and for general
corporate purposes. The securities have not been registered under the Securities
Act of  1933  and may  not be  offered  or  sold  in the  United  States  absent
registration or an applicable exemption from registration requirements.

Gary Brooks, President of Positron commented, "Proceeds from this private equity
financing will provide us with sufficient  working capital to re-launch Positron
and begin  manufacturing  and  marketing of the company's  Posicam(TM)  positron
emission tomography (PET) scanners.  The company's capital infusion comes on the
heels of recent favorable reimbursement recommendations for a broad range of PET
procedures  from the U.S.  Health  Care  Financing  Administration  (HCFA),  the
federal agency which oversees Medicare.  Currently,  eight clinical applications
utilizing  PET have  been  approved  by HCFA for  reimbursement:  five  oncology
procedures,  two  cardiology  procedures and one neurology  procedure.  HCFA has
stated that, `as scientific evidence becomes available showing the effectiveness
of new technologies to diagnose and manage certain cancers,  the  administration
will act fast to ensure access to safe and effective  technology.' Based on this
positive  reimbursement  trend, we are optimistic that additional PET procedures
will be approved for reimbursement by HCFA in the future."

Mr.  Brooks  continued,  "This is an exciting and  challenging  turning point in
Positron's  history.  As we  rebuild  the  company  and  move  forward  with the
company's sales and marketing plans, management will prudently monitor costs and
invest in  Positron's  growth in parallel  with our  continued  success.  We are
actively seeking qualified  individuals to fill critical executive  positions to
strengthen  the  company's  management  team.  We look  forward to  keeping  our
shareholders apprised of our progress as we achieve our business objectives."

S. Lewis Meyer, CEO of Imatron, stated, "As the largest shareholder of Positron,
the  completion  of this equity  financing  provides  Imatron  with an excellent
baseline  for the  valuation  of our nine million  share  ownership  position in
Positron. In addition, a portion of the proceeds from the financing will be used
to repay Imatron's  $600,000  working capital loan and interest to Positron.  We
are  encouraged  by the current  reimbursement  climate for PET  procedures  and
believe that  Imatron's  investment in Positron  will  appreciate as the company
establishes  itself as a  commercially  viable  participant  in the PET  imaging
marketplace delivering value to Imatron's shareholders."

Mr. Meyer continued, "One of the strategic objectives of Imatron's investment in
Positron was to secure product flow to Imatron-Japan,  the exclusive distributor
of  Positron's  Posicam  PET  scanners  in Japan.  Given the recent  approval of
Posicam  systems by the  Japanese  Ministry of Health & Welfare  (MHW),  and the
proceeds from the equity financing,  we believe that Positron is now in a strong
position  to  complete  an open order from  Imatron-Japan  for  delivery  of ten
Posicam systems over the next 36 months."

Positron Corporation is primarily engaged in designing, manufacturing, marketing
and supporting  advanced  medical imaging devices  utilizing  positron  emission
tomography  (PET)   technology   under  the  trade  name  POSICAM(TM)   systems.

including   the   Cleveland   Clinic   Foundation,    Yale   University/Veterans
Administration,  Crawford Long Hospital,  Hermann Hospital and the University of

differ  materially  include,  among others:  failed  clinical  demonstration  of
certain asserted technological advantages and diagnostic capabilities;  reliance
on product distributors;  competition in the diagnostic imaging market;  failure
to improve product reliability or introduce new product models and enhancements;
delays in production and difficulty in obtaining  components and  sub-assemblies
from limited sources of supply; inability to meet cash-on-delivery or prepayment
terms from vendors;  determinations by regulatory and administrative  government
authorities;  patent expiration and denial of patent applications; the high cost
of the scanner as compared to commercially  available CT scanners;  and the risk
factors  listed  from  time to time in the  Company's  Securities  and  Exchange
Commission  reports,  including  their  reports  on Form 10-K for their  current
fiscal year.
