                     INVESTOR REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of June 21,
2004, by and among PRODUCTIVITY TECHNOLOGIES CORPORATION, a Delaware corporation
(the  "Company"),  and  the  undersigned  investors  (each,  an  "Investor"  and
collectively, the "Investors").

     WHEREAS:

     A. In connection  with the Securities  Purchase  Agreement by and among the
parties hereto of even date herewith (the "Securities Purchase Agreement"),  the
Company  has  agreed,  upon the  terms  and  subject  to the  conditions  of the
Securities  Purchase  Agreement,  to  issue  and sell to the  Investors  secured
convertible debentures (the "Convertible Debentures") which shall be convertible
into that number of shares of the Company's common stock, par value US$0.001 per
share (the "Common  Stock"),  pursuant to the terms of the  Securities  Purchase
Agreement for an aggregate  purchase  price of up to Five Hundred Sixty Thousand
U.S. Dollars  (US$560,000).  Capitalized terms not defined herein shall have the
meaning ascribed to them in the Securities Purchase Agreement.

     B. To induce the Investors to execute and deliver the  Securities  Purchase
Agreement,  the Company has agreed to provide certain  registration rights under
the  Securities  Act of 1933, as amended,  and the rules and  regulations  there
under, or any similar  successor  statute  (collectively,  the "1933 Act"),  and
applicable state securities laws.

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
contained  herein and other good and  valuable  consideration,  the  receipt and
sufficiency  of which are hereby  acknowledged,  the Company  and the  Investors
hereby agree as follows:

     1. DEFINITIONS.

     As used in this  Agreement,  the  following  terms shall have the following
meanings:

          (a) "Person"  means a corporation,  a limited  liability  company,  an
     association, a partnership,  an organization,  a business, an individual, a
     governmental or political subdivision thereof or a governmental agency.

          (b)  "Register,"   "registered,"   and   "registration"   refer  to  a
     registration  effected  by  preparing  and filing one or more  Registration
     Statements (as defined below) in compliance  with the 1933 Act and pursuant
     to Rule 415 under the 1933 Act or any successor rule providing for offering
     securities  on  a  continuous  or  delayed  basis  ("Rule  415"),  and  the
     declaration or ordering of effectiveness of such Registration  Statement(s)
     by the United States Securities and Exchange SEC (the "SEC").

          (c) "Registrable Securities" means the shares of Common Stock issuable
     to Investors upon conversion of the Convertible  Debentures pursuant to the
     Securities  Purchase



     Agreement and the Investor's Shares, as this term is defined in the Standby
     Equity Distribution Agreement dated the date hereof.

          (d) "Registration  Statement" means a registration statement under the
     1933 Act which covers the Registrable Securities.

     2. REGISTRATION.

          (a) Subject to the terms and conditions of this Agreement, the Company
     shall prepare and file, no later than thirty (30) days from the date hereof
     (the "Scheduled Filing Deadline"), with the SEC a registration statement on
     Form S-1 or SB-2 (or, if the Company is then  eligible,  on Form S-3) under
     the 1933 Act (the "Initial  Registration  Statement") for the  registration
     for the  resale  by all  Investors  who  purchased  Convertible  Debentures
     pursuant to the Securities  Purchase  Agreement  _________ shares of Common
     Stock to be issued upon  conversion of the  Convertible  Debentures  issued
     pursuant to the Securities  Purchase  Agreement and the Investor's  Shares.
     The Company  shall cause the  Registration  Statement  to remain  effective
     until all of the Registrable Securities have been sold. Prior to the filing
     of the  Registration  Statement  with the SEC, the Company  shall furnish a
     copy of the Initial  Registration  Statement  to the  Investors  and Butler
     Gonzalez  LLP for their  review  and  comment.  The  Investors  and  Butler
     Gonzalez LLP shall furnish comments on the Initial  Registration  Statement
     to the Company within  twenty-four  (24) hours of the receipt  thereof from
     the Company.

          (b) Effectiveness of the Initial Registration  Statement.  The Company
     shall use its best efforts (i) to have the Initial  Registration  Statement
     declared effective by the SEC no later than ninety (90) days after the date
     hereof (the  "Scheduled  Effective  Deadline")  and (ii) to insure that the
     Initial Registration  Statement and any subsequent  Registration  Statement
     remains in effect until all of the  Registrable  Securities have been sold,
     subject to the terms and conditions of this Agreement.

          (c)  Failure  to  File or  Obtain  Effectiveness  of the  Registration
     Statement.  In the event  the  Registration  Statement  is not filed by the
     Scheduled  Filing  Deadline or is not  declared  effective by the SEC on or
     before the Scheduled Effective Date, or if after the Registration Statement
     has been  declared  effective by the SEC,  sales cannot be made pursuant to
     the  Registration  Statement  (whether  because  of a  failure  to keep the
     Registration  Statement effective,  failure to disclose such information as
     is necessary for sales to be made pursuant to the  Registration  Statement,
     failure to register  sufficient shares of Common Stock or otherwise then as
     partial relief for the damages to any holder of  Registrable  Securities by
     reason  of any  such  delay  in or  reduction  of its  ability  to sell the
     underlying  shares of Common Stock (which  remedy shall not be exclusive of
     any other remedies at law or in equity), the Company will pay as liquidated
     damages (the "Liquidated  Damages") to the holder,  at the holder's option,
     either a cash amount or shares of the  Company's  Common Stock within three
     (3) business days, after demand therefore, equal to two percent (2%) of the
     outstanding principal balance of the Convertible  Debentures outstanding as
     Liquidated  Damages  for each  thirty  (30) day period or any part  thereof
     after the Scheduled Filing Deadline or the Scheduled  Effective Date as the
     case may be.


          (d)  Liquidated   Damages.   The  Company  and  the  Investor   hereto
     acknowledge  and agree that the sums payable  under  subsection  2(c) above
     shall constitute  liquidated  damages and not penalties and are in addition
     to all other rights of the Investor, including the right to call a default.
     The  parties  further  acknowledge  that (i) the  amount of loss or damages
     likely to be incurred is incapable  or is difficult to precisely  estimate,
     (ii)  the  amounts   specified  in  such   subsections  bear  a  reasonable
     relationship  to, and are not plainly or grossly  disproportionate  to, the
     probable loss likely to be incurred in  connection  with any failure by the
     Company  to  obtain  or  maintain  the   effectiveness  of  a  Registration
     Statement,  (iii)  one of the  reasons  for the  Company  and the  Investor
     reaching an agreement as to such  amounts was the  uncertainty  and cost of
     litigation  regarding the question of actual damages,  and (iv) the Company
     and  the  Investor  are  sophisticated   business  parties  and  have  been
     represented by  sophisticated  and able legal counsel and  negotiated  this
     Agreement at arm's length.

     3. RELATED OBLIGATIONS.

          (a) The  Company  shall  keep  the  Registration  Statement  effective
     pursuant  to Rule 415 at all times  until  the date on which  the  Investor
     shall have sold all the Registrable Securities covered by such Registration
     Statement  (the  "Registration   Period"),   which  Registration  Statement
     (including any amendments or supplements thereto and prospectuses contained
     therein) shall not contain any 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,  in light of the  circumstances in which they
     were made, not misleading.

          (b) The Company  shall  prepare and file with the SEC such  amendments
     (including  post-effective  amendments)  and  supplements to a Registration
     Statement  and the  prospectus  used in connection  with such  Registration
     Statement, which prospectus is to be filed pursuant to Rule 424 promulgated
     under the 1933 Act, as may be necessary to keep such Registration Statement
     effective at all times during the  Registration  Period,  and,  during such
     period,  comply  with the  provisions  of the 1933 Act with  respect to the
     disposition of all  Registrable  Securities of the Company  covered by such
     Registration   Statement  until  such  time  as  all  of  such  Registrable
     Securities  shall have been  disposed of in  accordance  with the  intended
     methods of  disposition  by the  seller or sellers  thereof as set forth in
     such Registration Statement. In the case of amendments and supplements to a
     Registration  Statement  which are  required  to be filed  pursuant to this
     Agreement  (including  pursuant  to this  Section  3(b)) by  reason  of the
     Company's  filing a report on Form  10-KSB,  Form 10-QSB or Form 8-K or any
     analogous report under the Securities Exchange Act of 1934, as amended (the
     "1934 Act"),  the Company shall  incorporate  such report by reference into
     the Registration Statement, if applicable, or shall file such amendments or
     supplements  with the SEC on the same day on which  the 1934 Act  report is
     filed which created the  requirement for the Company to amend or supplement
     the Registration Statement.

          (c) The  Company  shall  furnish to each  Investor  whose  Registrable
     Securities are included in any Registration Statement,  without charge, (i)
     at least one (1) copy of such Registration  Statement as declared effective
     by the SEC and any amendment(s) thereto, including financial statements and
     schedules,  all documents  incorporated therein by reference,  all exhibits
     and  each  preliminary  prospectus,  (ii)  ten  (10)  copies  of the  final
     prospectus  included in such Registration  Statement and all amendments and
     supplements  thereto (or such other  number



     of copies as such  Investor  may  reasonably  request) and (iii) such other
     documents  as such  Investor  may  reasonably  request from time to time in
     order to facilitate the disposition of the Registrable  Securities owned by
     such Investor.

          (d) The Company shall use its best efforts to (i) register and qualify
     the Registrable  Securities covered by a Registration  Statement under such
     other  securities  or "blue sky" laws of such  jurisdictions  in the United
     States as any Investor reasonably requests,  (ii) prepare and file in those
     jurisdictions,  such amendments (including  post-effective  amendments) and
     supplements to such registrations and qualifications as may be necessary to
     maintain the effectiveness  thereof during the Registration  Period,  (iii)
     take such other actions as may be necessary to maintain such  registrations
     and  qualifications in effect at all times during the Registration  Period,
     and (iv)  take all other  actions  reasonably  necessary  or  advisable  to
     qualify  the  Registrable   Securities  for  sale  in  such  jurisdictions;
     provided,  however,  that the Company  shall not be required in  connection
     therewith  or as a  condition  thereto  to  (w)  make  any  change  to  its
     certificate of incorporation or by-laws,  (x) qualify to do business in any
     jurisdiction  where it would not  otherwise  be required to qualify but for
     this  Section  3(d),  (y)  subject  itself to general  taxation in any such
     jurisdiction,  or (z) file a general  consent  to service of process in any
     such  jurisdiction.  The Company  shall  promptly  notify each Investor who
     holds  Registrable  Securities  of  the  receipt  by  the  Company  of  any
     notification  with  respect  to  the  suspension  of  the  registration  or
     qualification  of any of the  Registrable  Securities  for sale  under  the
     securities or "blue sky" laws of any  jurisdiction  in the United States or
     its receipt of actual notice of the  initiation or threat of any proceeding
     for such purpose.

          (e) As promptly as  practicable  after becoming aware of such event or
     development,  the  Company  shall  notify  each  Investor in writing of the
     happening  of any event as a result of which the  prospectus  included in a
     Registration  Statement, as then in effect, includes an untrue statement of
     a material  fact or omission to state a material fact required to be stated
     therein  or  necessary  to make  the  statements  therein,  in light of the
     circumstances under which they were made, not misleading  (provided that in
     no event shall such notice  contain any material,  nonpublic  information),
     and  promptly  prepare  a  supplement  or  amendment  to such  Registration
     Statement  to correct such untrue  statement  or omission,  and deliver ten
     (10) copies of such  supplement or amendment to each Investor.  The Company
     shall also  promptly  notify each Investor in writing (i) when a prospectus
     or any prospectus  supplement or  post-effective  amendment has been filed,
     and when a  Registration  Statement  or any  post-effective  amendment  has
     become effective  (notification of such effectiveness shall be delivered to
     each Investor by facsimile on the same day of such effectiveness),  (ii) of
     any request by the SEC for  amendments  or  supplements  to a  Registration
     Statement or related  prospectus or related  information,  and (iii) of the
     Company's  reasonable  determination  that a post-effective  amendment to a
     Registration Statement would be appropriate.

          (f) The Company  shall use its best efforts to prevent the issuance of
     any stop  order or other  suspension  of  effectiveness  of a  Registration
     Statement, or the suspension of the qualification of any of the Registrable
     Securities for sale in any jurisdiction within the United States of America
     and, if such an order or suspension is issued,  to obtain the withdrawal of
     such order or suspension at the earliest possible moment and to notify each
     Investor  who holds  Registrable  Securities  being sold of the issuance of
     such order and the  resolution  thereof or its receipt of actual  notice of
     the initiation or threat of any proceeding for such purpose.


          (g) At the  reasonable  request of any  Investor,  the  Company  shall
     furnish  to  such  Investor,  on  the  date  of  the  effectiveness  of the
     Registration Statement and thereafter from time to time on such dates as an
     Investor may  reasonably  request (i) a letter,  dated such date,  from the
     Company's independent certified public accountants in form and substance as
     is  customarily  given  by  independent  certified  public  accountants  to
     underwriters in an underwritten public offering, and (ii) an opinion, dated
     as of such date, of counsel  representing  the Company for purposes of such
     Registration  Statement,  in form,  scope and  substance as is  customarily
     given in an underwritten public offering, addressed to the Investors.

(h)  The Company  shall make  available  for  inspection by (i) any Investor and
     (ii) one (1) firm of accountants or other agents  retained by the Investors
     (collectively, the "Inspectors") all pertinent financial and other records,
     and  pertinent   corporate   documents   and   properties  of  the  Company
     (collectively,  the "Records"),  as shall be reasonably deemed necessary by
     each Inspector,  and cause the Company's officers,  directors and employees
     to supply all  information  which any  Inspector  may  reasonably  request;
     provided,  however,  that each  Inspector  shall agree,  and each  Investor
     hereby  agrees,  to hold in  strict  confidence  and  shall  not  make  any
     disclosure  (except to an Investor) or use any Record or other  information
     which the Company determines in good faith to be confidential, and of which
     determination the Inspectors are so notified,  unless (a) the disclosure of
     such Records is necessary to avoid or correct a misstatement or omission in
     any Registration Statement or is otherwise required under the 1933 Act, (b)
     the release of such Records is ordered pursuant to a final,  non-appealable
     subpoena  or  order  from  a  court  or   government   body  of   competent
     jurisdiction,  or (c)  the  information  in  such  Records  has  been  made
     generally  available to the public other than by disclosure in violation of
     this or any other  agreement  of which the  Inspector  and the Investor has
     knowledge.   Each  Investor  agrees  that  it  shall,  upon  learning  that
     disclosure of such Records is sought in or by a court or governmental  body
     of competent jurisdiction or through other means, give prompt notice to the
     Company and allow the  Company,  at its expense,  to undertake  appropriate
     action to prevent  disclosure of, or to obtain a protective  order for, the
     Records deemed confidential.

          (i) The Company shall hold in confidence  and not make any  disclosure
     of  information  concerning an Investor  provided to the Company unless (i)
     disclosure of such information is necessary to comply with federal or state
     securities  laws,  (ii) the disclosure of such  information is necessary to
     avoid or correct a misstatement or omission in any Registration  Statement,
     (iii) the release of such  information is ordered pursuant to a subpoena or
     other  final,  non-appealable  order from a court or  governmental  body of
     competent  jurisdiction,  or (iv) such  information has been made generally
     available  to the public  other than by  disclosure  in  violation  of this
     Agreement or any other  agreement.  The Company agrees that it shall,  upon
     learning  that  disclosure  of such  information  concerning an Investor is
     sought in or by a court or governmental  body of competent  jurisdiction or
     through other means,  give prompt written notice to such Investor and allow
     such Investor,  at the Investor's expense, to undertake  appropriate action
     to  prevent  disclosure  of,  or to obtain a  protective  order  for,  such
     information.

          (j) The  Company  shall use its best  efforts  either to cause all the
     Registrable Securities covered by a Registration Statement (i) to be listed
     on each securities exchange on which securities of the same class or series
     issued by the  Company  are then  listed,  if any,  if the  listing of such
     Registrable  Securities is then permitted  under the rules of such exchange
     or



     (ii) the inclusion for quotation on the National  Association of Securities
     Dealers,  Inc.  OTC Bulletin  Board for such  Registrable  Securities.  The
     Company shall pay all fees and expenses in connection  with  satisfying its
     obligation under this Section 3(j).

          (k)  The  Company  shall   cooperate   with  the  Investors  who  hold
     Registrable  Securities  being  offered and, to the extent  applicable,  to
     facilitate the timely preparation and delivery of certificates (not bearing
     any  restrictive  legend)  representing  the  Registrable  Securities to be
     offered pursuant to a Registration  Statement and enable such  certificates
     to be in  such  denominations  or  amounts,  as the  case  may  be,  as the
     Investors  may  reasonably  request  and  registered  in such  names as the
     Investors may request.

          (l) The Company  shall use its best  efforts to cause the  Registrable
     Securities  covered  by  the  applicable   Registration   Statement  to  be
     registered  with  or  approved  by  such  other  governmental  agencies  or
     authorities  as may be  necessary to  consummate  the  disposition  of such
     Registrable Securities.

          (m) The Company shall make generally available to its security holders
     as soon as  practical,  but not later than ninety (90) days after the close
     of the period  covered  thereby,  an earnings  statement (in form complying
     with the  provisions of Rule 158 under the 1933 Act) covering a twelve (12)
     month period beginning not later than the first day of the Company's fiscal
     quarter next following the effective date of the Registration Statement.

          (n) The Company  shall  otherwise  use its best efforts to comply with
     all  applicable  rules and  regulations  of the SEC in connection  with any
     registration hereunder.

          (o) Within two (2) business days after a Registration  Statement which
     covers Registrable Securities is declared effective by the SEC, the Company
     shall deliver, and shall cause legal counsel for the Company to deliver, to
     the  transfer  agent for such  Registrable  Securities  (with copies to the
     Investors whose  Registrable  Securities are included in such  Registration
     Statement)  confirmation that such Registration Statement has been declared
     effective by the SEC in the form attached hereto as Exhibit A.

          (p) The Company shall take all other reasonable  actions  necessary to
     expedite  and  facilitate  disposition  by  the  Investors  of  Registrable
     Securities pursuant to a Registration Statement.

     4. OBLIGATIONS OF THE INVESTORS.

     Each Investor  agrees that,  upon receipt of any notice from the Company of
the  happening  of any event of the kind  described in Section 3(f) or the first
sentence of 3(e),  such Investor will  immediately  discontinue  disposition  of
Registrable  Securities pursuant to any Registration  Statement(s) covering such
Registrable  Securities  until  such  Investor's  receipt  of the  copies of the
supplemented  or amended  prospectus  contemplated by Section 3(e) or receipt of
notice that no supplement or amendment is required.  Notwithstanding anything to
the contrary,  the Company shall cause its transfer agent to deliver  unlegended
certificates  for  shares of Common  Stock to a  transferee  of an  Investor  in
accordance  with the terms of the  Securities  Purchase  Agreement in connection
with any sale of  Registrable  Securities  with respect to which an Investor has
entered  into a contract  for sale prior to the  Investor's  receipt of a notice
from the



Company of the  happening of any event of the kind  described in Section 3(f) or
the first sentence of 3(e) and for which the Investor has not yet settled.

     5. EXPENSES OF REGISTRATION.

     All  expenses  incurred  in  connection  with  registrations,   filings  or
qualifications pursuant to Sections 2 and 3, including,  without limitation, all
registration,  listing and qualifications fees,  printers,  legal and accounting
fees shall be paid by the Company.

     6. INDEMNIFICATION.

     With respect to Registrable Securities which are included in a Registration
Statement under this Agreement:

          (a) To the fullest  extent  permitted  by law, the Company  will,  and
     hereby  does,  indemnify,  hold  harmless  and defend  each  Investor,  the
     directors,  officers, partners, employees, agents,  representatives of, and
     each Person,  if any,  who controls any Investor  within the meaning of the
     1933 Act or the 1934 Act  (each,  an  "Indemnified  Person"),  against  any
     losses, claims, damages, liabilities, judgments, fines, penalties, charges,
     costs,  reasonable attorneys' fees, amounts paid in settlement or expenses,
     joint  or  several  (collectively,  "Claims")  incurred  in  investigating,
     preparing  or  defending  any action,  claim,  suit,  inquiry,  proceeding,
     investigation  or appeal taken from the foregoing by or before any court or
     governmental,  administrative or other regulatory agency,  body or the SEC,
     whether  pending or threatened,  whether or not an indemnified  party is or
     may be a party thereto  ("Indemnified  Damages"),  to which any of them may
     become subject insofar as such Claims (or actions or  proceedings,  whether
     commenced  or  threatened,  in respect  thereof)  arise out of or are based
     upon: (i) any untrue  statement or alleged  untrue  statement of a material
     fact in a Registration Statement or any post-effective amendment thereto or
     in any filing made in  connection  with the  qualification  of the offering
     under the securities or other "blue sky" laws of any  jurisdiction in which
     Registrable  Securities are offered ("Blue Sky Filing"), or the omission or
     alleged  omission to state a material fact required to be stated therein or
     necessary to make the statements  therein not  misleading;  (ii) any untrue
     statement or alleged  untrue  statement of a material fact contained in any
     final  prospectus  (as amended or  supplemented,  if the Company  files any
     amendment  thereof or  supplement  thereto with the SEC) or the omission or
     alleged  omission to state therein any material fact  necessary to make the
     statements  made  therein,  in light of the  circumstances  under which the
     statements  therein were made,  not  misleading;  or (iii) any violation or
     alleged  violation  by the Company of the 1933 Act, the 1934 Act, any other
     law, including,  without limitation,  any state securities law, or any rule
     or regulation  there under relating to the offer or sale of the Registrable
     Securities  pursuant  to a  Registration  Statement  (the  matters  in  the
     foregoing clauses (i) through (iii) being, collectively, "Violations"). The
     Company shall  reimburse the  Investors  and each such  controlling  person
     promptly as such  expenses are  incurred  and are due and payable,  for any
     legal fees or disbursements or other reasonable  expenses  incurred by them
     in   connection   with   investigating   or   defending   any  such  Claim.
     Notwithstanding   anything   to  the   contrary   contained   herein,   the
     indemnification  agreement  contained in this Section  6(a):  (x) shall not
     apply to a Claim by an  Indemnified  Person  arising out of or based upon a
     Violation which occurs in reliance upon and in conformity with  information
     furnished in writing to the Company by such  Indemnified  Person  expressly
     for use in connection with the preparation of the Registration



     Statement or any such amendment  thereof or supplement  thereto;  (y) shall
     not be  available  to the  extent  such  Claim is based on a failure of the
     Investor  to  deliver  or to  cause to be  delivered  the  prospectus  made
     available by the Company,  if such  prospectus was timely made available by
     the Company  pursuant to Section  3(c);  and (z) shall not apply to amounts
     paid in settlement of any Claim if such settlement is effected  without the
     prior  written  consent  of  the  Company,   which  consent  shall  not  be
     unreasonably withheld. Such indemnity shall remain in full force and effect
     regardless  of any  investigation  made by or on behalf of the  Indemnified
     Person and shall survive the transfer of the Registrable  Securities by the
     Investors pursuant to Section 9 hereof.

          (b) In connection with a Registration Statement,  each Investor agrees
     to severally and not jointly  indemnify,  hold harmless and defend,  to the
     same  extent and in the same  manner as is set forth in Section  6(a),  the
     Company,  each  of  its  directors,   each  of  its  officers,   employees,
     representatives,  or agents  and each  Person,  if any,  who  controls  the
     Company  within  the  meaning  of the 1933  Act or the  1934  Act  (each an
     "Indemnified Party"), against any Claim or Indemnified Damages to which any
     of them may become subject,  under the 1933 Act, the 1934 Act or otherwise,
     insofar as such Claim or Indemnified  Damages arise out of or is based upon
     any  Violation,  in each case to the extent,  and only to the extent,  that
     such  Violation  occurs in reliance  upon and in  conformity  with  written
     information  furnished to the Company by such Investor expressly for use in
     connection with such Registration Statement;  and, subject to Section 6(d),
     such  Investor  will  reimburse  any  legal  or other  expenses  reasonably
     incurred by them in  connection  with  investigating  or defending any such
     Claim;  provided,  however,  that the indemnity agreement contained in this
     Section 6(b) and the agreement  with respect to  contribution  contained in
     Section 7 shall not apply to  amounts  paid in  settlement  of any Claim if
     such  settlement  is  effected  without the prior  written  consent of such
     Investor,  which  consent  shall not be  unreasonably  withheld;  provided,
     further, however, that the Investor shall be liable under this Section 6(b)
     for only that amount of a Claim or  Indemnified  Damages as does not exceed
     the net  proceeds to such  Investor as a result of the sale of  Registrable
     Securities  pursuant to such Registration  Statement.  Such indemnity shall
     remain in full force and effect regardless of any investigation  made by or
     on behalf of such  Indemnified  Party and shall survive the transfer of the
     Registrable   Securities   by  the   Investors   pursuant   to  Section  9.
     Notwithstanding   anything   to  the   contrary   contained   herein,   the
     indemnification  agreement  contained  in this Section 6(b) with respect to
     any prospectus  shall not inure to the benefit of any Indemnified  Party if
     the  untrue  statement  or  omission  of  material  fact  contained  in the
     prospectus  was  corrected  and such new  prospectus  was delivered to each
     Investor prior to such  Investor's use of the prospectus to which the Claim
     relates.

          (c) Promptly  after receipt by an  Indemnified  Person or  Indemnified
     Party under this Section 6 of notice of the  commencement  of any action or
     proceeding  (including any governmental  action or proceeding)  involving a
     Claim,  such Indemnified  Person or Indemnified  Party shall, if a Claim in
     respect  thereof is to be made  against any  indemnifying  party under this
     Section  6,  deliver  to the  indemnifying  party a  written  notice of the
     commencement  thereof,  and the indemnifying  party shall have the right to
     participate  in,  and,  to the extent the  indemnifying  party so  desires,
     jointly with any other  indemnifying  party  similarly  noticed,  to assume
     control of the defense  thereof with counsel  mutually  satisfactory to the
     indemnifying  party and the Indemnified Person or the Indemnified Party, as
     the  case  may  be;  provided,  however,  that  an  Indemnified  Person  or
     Indemnified  Party shall have the right to retain its own counsel  with the
     fees and  expenses of not more than one (1)  counsel  for such  Indemnified
     Person or Indemnified



     Party to be paid by the indemnifying  party, if, in the reasonable  opinion
     of counsel retained by the indemnifying  party, the  representation by such
     counsel of the Indemnified Person or Indemnified Party and the indemnifying
     party would be inappropriate due to actual or potential differing interests
     between such  Indemnified  Person or Indemnified  Party and any other party
     represented by such counsel in such  proceeding.  The Indemnified  Party or
     Indemnified  Person shall  cooperate fully with the  indemnifying  party in
     connection  with any  negotiation or defense of any such action or claim by
     the  indemnifying  party and shall  furnish to the  indemnifying  party all
     information  reasonably  available to the Indemnified  Party or Indemnified
     Person which relates to such action or claim. The indemnifying  party shall
     keep the  Indemnified  Party or  Indemnified  Person fully  apprised at all
     times as to the status of the defense or any settlement  negotiations  with
     respect thereto.  No indemnifying  party shall be liable for any settlement
     of any action,  claim or  proceeding  effected  without  its prior  written
     consent;   provided,   however,  that  the  indemnifying  party  shall  not
     unreasonably  withhold,  delay or condition  its consent.  No  indemnifying
     party shall,  without the prior written consent of the Indemnified Party or
     Indemnified  Person,  consent  to entry of any  judgment  or enter into any
     settlement or other  compromise  which does not include as an unconditional
     term thereof the giving by the  claimant or  plaintiff to such  Indemnified
     Party or  Indemnified  Person of a release from all liability in respect to
     such  claim  or  litigation.  Following  indemnification  as  provided  for
     hereunder,  the indemnifying party shall be subrogated to all rights of the
     Indemnified Party or Indemnified  Person with respect to all third parties,
     firms or corporations  relating to the matter for which indemnification has
     been made. The failure to deliver written notice to the indemnifying  party
     within a reasonable  time of the  commencement of any such action shall not
     relieve such indemnifying  party of any liability to the Indemnified Person
     or  Indemnified  Party under this  Section 6, except to the extent that the
     indemnifying party is prejudiced in its ability to defend such action.

          (d) The  indemnification  required by this  Section 6 shall be made by
     periodic   payments  of  the  amount  thereof  during  the  course  of  the
     investigation  or defense,  as and when bills are  received or  Indemnified
     Damages are incurred.

          (e) The indemnity  agreements contained herein shall be in addition to
     (i) any  cause of  action  or  similar  right of the  Indemnified  Party or
     Indemnified  Person against the indemnifying  party or others, and (ii) any
     liabilities the indemnifying party may be subject to pursuant to the law.

     7. CONTRIBUTION.

     To the extent any indemnification by an indemnifying party is prohibited or
limited by law, the indemnifying  party agrees to make the maximum  contribution
with respect to any amounts for which it would otherwise be liable under Section
6 to the fullest extent permitted by law; provided, however, that: (i) no seller
of Registrable  Securities  guilty of fraudulent  misrepresentation  (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any  seller  of  Registrable   Securities  who  was  not  guilty  of  fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities
shall be limited in amount to the net amount of proceeds received by such seller
from the sale of such Registrable Securities.


     8. REPORTS UNDER THE 1934 ACT.

     With a view to making  available to the  Investors the benefits of Rule 144
promulgated under the 1933 Act or any similar rule or regulation of the SEC that
may at any time permit the  Investors to sell  securities  of the Company to the
public without registration ("Rule 144") the Company agrees to:

     (a)  make  and keep  public  information  available,  as  those  terms  are
understood and defined in Rule 144;

     (b) file with the SEC in a timely  manner all reports  and other  documents
required  of the  Company  under  the  1933  Act and the 1934 Act so long as the
Company remains subject to such  requirements  (it being understood that nothing
herein  shall  limit  the  Company's  obligations  under  Section  4(c)  of  the
Securities  Purchase  Agreement)  and the  filing  of  such  reports  and  other
documents as are required by the applicable provisions of Rule 144; and

     (c) furnish to each  Investor  so long as such  Investor  owns  Registrable
Securities,  promptly upon request,  (i) a written statement by the Company that
it has complied  with the reporting  requirements  of Rule 144, the 1933 Act and
the 1934 Act, (ii) a copy of the most recent  annual or quarterly  report of the
Company and such other reports and documents so filed by the Company,  and (iii)
such other information as may be reasonably requested to permit the Investors to
sell such securities pursuant to Rule 144 without registration.

9.       AMENDMENT OF REGISTRATION RIGHTS.

     Provisions of this Agreement may be amended and the observance  thereof may
be waived (either generally or in a particular instance and either retroactively
or  prospectively),  only with the written  consent of the Company and Investors
who then  hold at least  two-thirds  (2/3) of the  Registrable  Securities.  Any
amendment or waiver  effected in accordance with this Section 9 shall be binding
upon each Investor and the Company.  No such amendment shall be effective to the
extent  that it  applies to fewer  than all of the  holders  of the  Registrable
Securities.  No consideration shall be offered or paid to any Person to amend or
consent to a waiver or  modification  of any provision of any of this  Agreement
unless the same  consideration  also is  offered  to all of the  parties to this
Agreement.

     10. MISCELLANEOUS.

          (a) A Person  is  deemed  to be a  holder  of  Registrable  Securities
     whenever  such Person  owns or is deemed to own of record such  Registrable
     Securities.  If the Company receives conflicting  instructions,  notices or
     elections from two (2) or more Persons with respect to the same Registrable
     Securities, the Company shall act upon the basis of instructions, notice or
     election received from the registered owner of such Registrable Securities.

          (b) Any notices, consents, waivers or other communications required or
     permitted to be given under the terms of this  Agreement must be in writing
     and will be deemed to have been delivered: (i) upon receipt, when delivered
     personally;   (ii)  upon   receipt,   when  sent  by  facsimile   (provided
     confirmation of transmission  is mechanically or  electronically  generated
     and kept on file by the sending party); or (iii) one (1) business day after

          (c)  Failure of any party to exercise  any right or remedy  under this
     Agreement or  otherwise,  or delay by a party in  exercising  such right or
     remedy, shall not operate as a waiver thereof.

          (d) The laws of the  State  of New  Jersey  shall  govern  all  issues
     concerning  the  relative  rights of the Company and the  Investors  as its
     stockholders.  All other questions  concerning the construction,  validity,

     brought in an inconvenient  forum or that the venue of such suit, action or
     proceeding  is improper.  Each party  hereby  irrevocably  waives  personal
     service of



     process and consents to process  being  served in any such suit,  action or
     proceeding  by mailing a copy thereof to such party at the address for such

     constitute  good and  sufficient  service  of process  and notice  thereof.
     Nothing  contained  herein shall be deemed to limit in any way any right to
     serve  process in any manner  permitted  by law. If any  provision  of this
     Agreement  shall be  invalid or  unenforceable  in any  jurisdiction,  such
     invalidity   or   unenforceability   shall  not  affect  the   validity  or
     enforceability  of the remainder of this Agreement in that  jurisdiction or
     the validity or  enforceability  of any provision of this  Agreement in any
     other  jurisdiction.  EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY
     HAVE, AND AGREES NOT TO REQUEST,  A JURY TRIAL FOR THE  ADJUDICATION OF ANY
     DISPUTE  HEREUNDER  OR IN  CONNECTION  HEREWITH  OR  ARISING  OUT  OF  THIS

     constitute  the entire  agreement  among the parties hereto with respect to
     the subject matter hereof and thereof. There are no restrictions, promises,
     warranties  or  undertakings,  other  than those set forth or  referred  to

     including the Convertible Debenture,  the Escrow Agreement and the Security
     Agreement  supersede  all prior  agreements  and  understandings  among the
     parties hereto with respect to the subject matter hereof and thereof.

          (f) This  Agreement  shall inure to the benefit of and be binding upon
     the permitted successors and assigns of each of the parties hereto.

          (g) The headings in this  Agreement are for  convenience  of reference

     this  Agreement  bearing  the  signature  of the party so  delivering  this
     Agreement.

          (i)  Each  party  shall  do and  perform,  or  cause  to be  done  and
     performed,  all such further acts and things, and shall execute and deliver
     all such other agreements, certificates,  instruments and documents, as the
     other  party may  reasonably  request  in order to carry out the intent and
     accomplish  the  purposes of this  Agreement  and the  consummation  of the

Attention:

     Re: PRODUCTIVITY TECHNOLOGIES CORPORATION

Ladies and Gentlemen:

     We  are  counsel  to  Productivity  Technologies  Corporation,  a  Delaware
corporation (the "Company"), and have represented the Company in connection with
that certain Securities Purchase Agreement (the "Securities Purchase Agreement")
entered  into  by  and  among  the  Company  and  the  investors  named  therein
(collectively,  the  "Investors")  pursuant to which the  Company  issued to the
Investors  shares of its Common Stock, par value US$0.001 per share (the "Common
Stock"). Pursuant to the Purchase Agreement, the Company also has entered into a
Registration  Rights  Agreement with the Investors  (the "Investor  Registration
Rights Agreement")  pursuant to which the Company agreed, among other things, to
register  the  Registrable  Securities  (as defined in the  Registration  Rights
Agreement)  under the  Securities  Act of 1933, as amended (the "1933 Act").  In
connection  with  the  Company's   obligations  under  the  Registration  Rights
Agreement,  on ____________ ____, the Company filed a Registration  Statement on
Form ________ (File No.  333-_____________) (the "Registration  Statement") with
the  Securities  and  Exchange  SEC  (the  "SEC")  relating  to the  Registrable
Securities  which names each of the  Investors  as a selling  stockholder  there
under.

     In connection with the foregoing,  we advise you that a member of the SEC's
staff has advised us by  telephone  that the SEC has entered an order  declaring
the  Registration  Statement  effective  under  the 1933 Act at  [ENTER  TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,  after
telephonic  inquiry  of a  member  of the  SEC's  staff,  that  any  stop  order
suspending its  effectiveness  has been issued or that any  proceedings for that
purpose  are  pending  before,  or  threatened  by, the SEC and the  Registrable
Securities  are  available  for  resale  under  the  1933  Act  pursuant  to the
Registration Statement.

                                       Very truly yours,

                                       KIRKPATRICK & LOCKHART LLP

                                       By:
