10.    DISPUTE RESOLUTION.

       10.1   Any dispute,  controversy  or claim  arising out of or relating to
this Agreement or any related agreement or the validity, interpretation,  breach
or  termination  thereof (a  "DISPUTE"),  including  claims  seeking  redress or
asserting  rights under applicable law, shall be resolved in accordance with the
procedures set forth herein.  Until completion of such procedures,  no party may
take any action not contemplated  herein to force a resolution of the Dispute by
any judicial or similar process,  except to the limited extent necessary to; (i)
avoid expiration of a claim that might eventually be permitted  hereby;  or (ii)
obtain interim relief,  including  injunctive relief, to preserve the STATUS QUO
or prevent irreparable harm.

       10.2   In connection  with any Dispute,  the parties  expressly waive and
forego any right to trial by jury.

       10.3   Any Dispute will be resolved first through good faith negotiations
between the agreement managers,  or as necessary the team leader of Licensee and
the executive of GEMS having  responsibility for the sale or use of the Software
involved.

       10.4   If within  sixty  (60)  calendar  days the  parties  are unable to
resolve the Dispute through good faith negotiation, either party may submit such
Dispute for resolution by mediation  pursuant to the Center for Public Resources
Model  Procedure  for  Mediation  of Business  Disputes  as then in effect.  The
mediation  shall be conducted in New York City.  Mediation  will continue for at
least thirty (30) calendar days unless the mediator  chooses to withdraw sooner.
At the  request  of either  party,  the  mediator  will be asked to  provide  an
evaluation of the Dispute and the parties' relative positions.  Each party shall
bear its own costs of mediation effort.

<PAGE>

       10.5   After  completion of any mediation  effort, a party may submit the
Dispute  for  resolution  by  arbitration   pursuant  to  the   Non-Administered
Arbitration  Rules of the  Center  for  Public  Resources  as in  effect  on the
Effective Date, unless the parties agree to adopt such rules as in effect at the
time  of the  arbitration.  The  arbitral  tribunal  shall  be  composed  of one
arbitrator;  and the  arbitration  shall be conducted  in New York City.  If the
answer to the  Dispute  is not found  within  the terms of this  Agreement,  the
arbitrator  shall  determine the Dispute in accordance with the governing law of
this  Agreement,  without  giving  effect to any  conflict of law rules or other
rules that might render such law  inapplicable  or  unavailable.  The prevailing
party in any arbitration  conducted under this Section 10.5 shall be entitled to
recover  from the other  party  (as part of the  arbitral  award or  order)  its
reasonable attorneys' fees and other costs of arbitration.

       10.6   The law applicable to the validity of this arbitration  provision,
the conduct of the arbitration,  the challenge to or enforcement of any arbitral
award or order or any other  question of arbitration  law or procedure  shall be
governed  exclusively by the Federal  Arbitration  Act, 9 U.S.C.  sections 1-16;
however,  the award can be modified  or vacated on grounds  cited in the Federal
Arbitration  Act or if the  arbitrator's  findings of facts are not supported by
substantial  evidence or the  conclusions of law are erroneous under the laws of
the State of New York.  The  parties  agree that the  federal  and state  courts
located  in the State of New York  shall have  exclusive  jurisdiction  over any
action brought to enforce this arbitration provision, and each party irrevocably
submits  to the  jurisdiction  of said  courts.  Notwithstanding  the  foregoing
sentence,  either  party  may  apply  to any  court of  competent  jurisdiction,
wherever situated, for enforcement of any judgment on an arbitral award.

       10.7   Each party hereby consents to a single,  consolidated  arbitration
proceeding of multiple claims,  or claims  involving more than two parties.  The
prevailing  party or parties in any  arbitration  conducted under this paragraph
shall be  entitled  to recover  from the other  party or parties (as part of the
arbitral  award or  order)  its or their  reasonable  attorneys'  fees and other
reasonable costs of arbitration.

11.    MISCELLANEOUS.

       11.1   GOVERNING LAW. The parties expressly  acknowledge that the laws of
the state of New York,  except its  conflict  of law  rules,  will  govern  this
Agreement and any Dispute hereunder.

hereto are the  complete  and  exclusive  statement of the terms of the contract

No prior proposals,  statements, course of dealing or usage of the trade will be
part of this Agreement.

       11.3   HEADINGS.  The  headings  in this  Agreement  are for  purposes of
convenience and

<PAGE>

ease of reference  only and shall not be construed to limit or otherwise  effect
the meaning of any part of this Agreement.

       11.4   WAIVER.  Any  waiver  of a  breach  of this  Agreement  must be in
writing and signed by the injured party.  The failure of either party to enforce
any  provision of this  Agreement  shall not be construed to be a waiver of such
provision,  nor in any way to affect the validity of this  Agreement or any part
hereof or the right of any  party  thereafter  to  enforce  each and every  such
provision.

       11.5   SEVERABILITY.  Wherever possible, each provision of this Agreement
shall  be  interpreted  in  such  manner  as to be  effective  and  valid  under
applicable law.  However,  if any one or more of the provisions  shall,  for any
reason,  be held to be invalid,  illegal or unenforceable  in any respect,  such
provision  shall be ineffective to the extent,  but only to the extent,  of such
invalidity, illegality or unenforceability without invalidating the remainder of
such  invalid,  illegal or  unenforceable  provision or  provisions or any other
provisions hereof, unless such a construction would be unreasonable.

       11.6   ASSIGNMENT.  This  Agreement  is personal to the parties and shall
not be assignable by either party without the prior written consent of the other
party. Notwithstanding the foregoing, GEMS may assign its rights and obligations
under this Agreement without  Licensee's  consent (a) to an affiliate of GEMS or
(b) incident to the transfer of all or  substantially  all of its business,  and
Licensee  may  assign its rights and  obligations  under this  Agreement  to any
purchaser of all or substantially all its business related to the Software. This
Agreement  shall be binding  upon and shall  inure to the benefit of the parties
hereto and their respective heirs, successors and permitted assigns.

       11.7   RELATIONSHIP  OF THE  PARTIES.  The  relationship  of the  parties
hereunder  shall be that of independent  contractors.  Nothing in this Agreement
shall be deemed to create a partnership,  joint venture or similar  relationship
between the  parties,  and no party shall be deemed to be the agent of the other
party.

       11.8   PUBLICITY.  Licensee shall not issue any press release, use any of
GEMS' other products or its name in promotional  activity, or otherwise publicly
announce or comment on this Agreement, without GEMS' prior written consent.

       11.9   COUNTERPARTS.  This  Agreement  may be  executed  in any number of
counterparts,  each of which shall be an original with the same effect as if the
signatures thereto and hereto were upon the same instrument.

      ----------------------------                 -----------------------------AGREEMENT FOR SERVICES

       THIS AGREEMENT FOR SERVICES (the "AGREEMENT") is entered into this 29th
day of June, 2003 (the "EFFECTIVE DATE"), by and between General Electric
Company, acting through and on behalf of its GE Medical Systems business
("GEMS"), and Positron Corporation ("SERVICE PROVIDER").

       WHEREAS, GEMS and Service Provider have entered into both that certain
Technology Purchase Agreement of even date herewith (the "PURCHASE AGREEMENT")
whereby Service Provider assigned, sold, transferred and conveyed to GEMS all
right, title and interest in and to certain Cardiac PET software and related
technology and all intellectual property embodied therein (collectively, the
"TECHNOLOGY");

       WHEREAS, GEMS desires to obtain from Service Provider certain services
related to (a) Service Provider's effecting the transfer from Service Provider
to GEMS of all portions of the Technology, including without limitation the
intellectual property embodied therein, and (b) Service Provider's assisting
GEMS in fully utilizing and exploiting the Technology, including without
limitation by answering GEMS' questions and providing assistance to GEMS
regarding the use and exploitation of the Technology (collectively, the
"SERVICES"); and

       WHEREAS, Service Provider is willing to provide the Services under the
terms and conditions set forth herein.

       NOW, THEREFORE, in consideration of the mutual covenants contained
herein, the parties agree as follows:

       1.     SERVICES. Service Provider will provide the Services, subject to
GEMS' payment of the fees set forth in Section 2 herein, during the Term (as
defined below) of this Agreement. The Services will include, without limitation,
the following: Service Provider will execute and deliver such other documents,
certificates, agreements and other writings and take such other commercially
reasonable actions as may be reasonably necessary or desirable in order to
consummate or implement expeditiously the transactions contemplated by this
Agreement, including, without limitation, (a) assigning or procuring the
assignment to GEMS of all Technology, (b) reasonably cooperating with GEMS and
its Affiliates to contest any legal proceeding challenging the assignments and
rights granted hereby or, at GEMS' sole expense, the validity of any
intellectual property in any of the Technology (the "INTELLECTUAL PROPERTY"),
(c) upon GEMS' request, giving such oaths, executing (or causing its affiliates
to execute) any additional instruments necessary (including assignments), and,
to effectuate the assignments contemplated under the Purchase Agreement, filing
same with the appropriate government entity (including, without limitation, the
U.S. Patent and Trademark Office and the U.S. Copyright Office), and (d)
reasonably cooperating with GEMS in any claim or suit GEMS or its affiliates
brings against third parties, in order to enforce GEMS' rights in the
Technology. GEMS and its affiliates may continue to conduct due diligence after
the Effective Date of the Purchase Agreement to verify that the transferred
Technology constitutes all of the software (other than software embedded in
Service Provider's PET scanners that is not cardiac-specific) necessary to
utilize the Technology as Service Provider utilized the same prior to the
Effective Date, except for such technology and intellectual property rights as
are commercially available. If GEMS or its affiliates reasonably conclude that
the appropriate rights and/or assets have not been transferred, then any
Technology and Intellectual Property, the addition of which would be necessary
to have the Technology constitute all of the software (other than software
embedded in Service Provider's PET scanners that is not cardiac-specific)
necessary to utilize the Technology as Service Provider utilized the same prior
to the Effective Date, except

<PAGE>

for such technology and intellectual property rights as are commercially
available, will be added to the list of Technology or Intellectual Property, as
applicable. If the relevant Technology or Intellectual Property is owned by an
affiliate of Service Provider, then Service Provider agrees to cause such
affiliate to effect the transfer of the relevant Technology or Intellectual
Property to GEMS at no additional cost to GEMS. Any Technology and Intellectual
Property that is subject to being added to the list of Technology or
Intellectual Property under the Purchase Agreement will be deemed to have been
included in such as of the Closing Date of the Purchase Agreement for purposes
of the Purchase Agreement.

       2.     FEES AND PAYMENT. As consideration for the Services provided by
Service Provider under this Agreement, GEMS will pay to Service Provider $50,000
per each 3-month period during the Term of this Agreement (each such period
hereinafter referred to as a "QUARTER"). GEMS will make payment of the first two
Quarters' $50,000 (total of $100,000) within two business days of the Effective
Date and will make payment of any subsequent Quarters during the Term in advance
of such Quarter. Service Provider will be responsible for paying all sales, use,
excise and other taxes, if any, that may be levied upon either party in
connection with this Agreement, except for taxes based on GEMS' net income.

       3.     TERM AND TERMINATION. The term of this Agreement will commence
upon the Effective Date and, unless earlier terminated as provided herein,
expire 6 Quarters (18 months) after the Effective Date (the period commencing on
the Effective Date and ending upon the expiration or earlier termination of this
Agreement hereinafter referred to as the "TERM"). GEMS may terminate this
Agreement at any time after it has paid the fees for at least 4 Quarters upon
providing at least 60 days' prior written notice to Service Provider.

       4.     REPRESENTATIONS, WARRANTIES AND COVENANTS.

              4.1    Service Provider covenants that it will at all times
perform the Services in a professional and workmanlike manner in accordance with
high industry standards.

              4.2    Other than as expressly stated in this Section, Service
Provider provides all services "AS IS" and without any warranty of any kind.
GEMS ACKNOWLEDGES THAT, EXCEPT AS EXPRESSLY PROVIDED HEREIN, SERVICE PROVIDER
HAS NOT MADE ANY REPRESENTATIONS, WARRANTIES OR COVENANTS, EXPRESS OR IMPLIED,
REGARDING THE SERVICES, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE OR IMPLIED WARRANTIES ARISING FROM COURSE OF
DEALING OR COURSE OF PERFORMANCE.

communicated by one party to the other concerning technology, know-how, product
development plans, business plans, pricing and customers, whether communicated
verbally or in

                                       2

writing; HOWEVER, Confidential Information does not include any information that
(a) can be shown was already known to the receiving party at the time of
disclosure, (b) is independently developed by the receiving party without any
use of or reference to the disclosing party's information, (c) is provided to

Information except as authorized by the disclosing party and not to use such
Confidential Information except as permitted hereunder. The prohibition on
disclosure will not apply to the extent that Confidential Information is
required to be disclosed as a matter of law or by order of a court, PROVIDED
THAT the receiving party uses reasonable efforts to provide the disclosing party
with prior of such requirement and reasonably assists in obtaining a protective
order therefor. Confidential Information of a party is and will remain the
property of such party, notwithstanding any permissible disclosure under this
Agreement.
