the  weighted  average  closing  price of IVP  shares  on the  OTCBB for the two
trading  days  prior to the  effective  date,  plus the  volume and price on the
effective  date and the two trading days following the effective date to produce
the  number of shares,  ______________  to be  delivered  as  consideration.  In

satisfactory  to  IVP,  to the  effect  that  such  transfer  does  not  require
registration under the Securities Act of 1933 (the "Securities Act").

            (b) The Shareholder agree to the imprinting,  so long as is required
by this Section 2.03, of a legend on the  certificates  representing  the Shares
substantially in the following form:

            THESE  SHARES  HAVE NOT BEEN  REGISTERED  WITH  THE  SECURITIES  AND
            EXCHANGE  COMMISSION  OR THE  SECURITIES  COMMISSION OF ANY STATE IN
            RELIANCE UPON AN EXEMPTION  FROM  REGISTRATION  UNDER THE SECURITIES
            ACT OF 1933, AS AMENDED (THE "SECURITIES  ACT"),  AND,  ACCORDINGLY,
            MAY  NOT  BE  OFFERED  OR  SOLD  EXCEPT  PURSUANT  TO  AN  EFFECTIVE
            REGISTRATION  STATEMENT  UNDER THE  SECURITIES ACT OR PURSUANT TO AN
            AVAILABLE  EXEMPTION  FROM, OR IN A TRANSACTION  NOT SUBJECT TO, THE
            REGISTRATION  REQUIREMENTS  OF THE  SECURITIES ACT AND IN ACCORDANCE
            WITH APPLICABLE STATE SECURITIES LAWS.

            2.04. Registration Rights with Respect to the Shares.

                  (a) Inclusion of Shares in Next  Registration  Statement.  IVP
shall include the Shares in the next  registration  statement  filed by it under
the  Securities Act  ("Registration  Statement"),  and,  subject to its right to
withdraw such filing as described below, shall use its best efforts to cause the
effectiveness  of the  Registration  Statement within ninety (90) days after the
filing thereof. Any such Registration  Statement may include other shares of IVP
Stock which IVP is obligated to register.  IVP shall maintain the  effectiveness
of the Registration Statement until the expiration of a period which is one year
after  the  Registration  Statement  is  declared  effective  by the SEC or such
earlier  date  when all  Shares  have been  sold or may be sold  without  volume
restrictions  pursuant to Rule 144(k)  promulgated  under the Securities Act, as
determined  by  counsel  to IVP  pursuant  to a written  opinion  letter to such
effect, addressed and acceptable to IVP's transfer agent.

                  (b) Postponement of Effective Date of Registration  Statement.
IVP  will be  entitled  to  postpone  or  interrupt  the  effective  date of any
Registration  Statement filed in connection with such  registration (and the use
of the prospectus  contained  therein) if IVP determines,  in its best judgment,
after consultation with counsel, that such registration  statement would require
the premature  announcement of any material  financing,  acquisition,  corporate
reorganization or other material corporate  transaction or development involving
IVP which, in IVP's reasonable determination, would be materially detrimental to
the interests of IVP and its stockholders. Any such postponement or interruption
will be for a  minimum  period  reasonably  required  to  avoid  such  premature
disclosure.  IVP promptly will give the Shareholder  notice of such postponement
or interruption.

                  (c) Additional  Registration  Procedures.  In connection  with
IVP's obligations to file a Registration Statement, it shall:

                        (i)  Notify  the  Shareholder  promptly  after  it shall
receive notice thereof, of the time when such Registration  Statement has become
effective with the SEC or a supplement to any prospectus  forming a part of such
Registration Statement (a "Prospectus") has been filed.

                        (ii)  Notify the  Shareholder  of any request by the SEC
for the amending or supplementing of such  Registration  Statement or Prospectus
or for additional information.

                        (iii) Prepare and file with the SEC such  amendments and
supplements to such  Registration  Statement and  Prospectus  used in connection
therewith as may be necessary to keep such Registration  Statement effective and
to comply with the provisions of the Securities Act with respect to the offer of
Shares covered by such  Registration  Statement  during the period  required for
distribution of such Shares, as provided in Section 2.04(a), above.

                                       5
<PAGE>

                        (iv) Furnish to the Shareholder such number of copies of
the Prospectus (including any preliminary  prospectus or supplemental or amended
prospectus) as the Shareholder may reasonably request in order to facilitate the
sale and distribution of the Shares.

                        (v) Prepare and file promptly with the SEC, and promptly
notify the  Shareholder  of the filing of, such  amendment or supplement to such
Registration  Statement or  Prospectus as may be necessary to correct any untrue
statements  of fact or  omissions  to  state  any  facts  necessary  to make the
statements  therein not misleading in light of the  circumstances  in which they
were made.

                        (vi) Advise the Shareholder,  promptly after it receives
notice or obtains  knowledge  thereof,  of the issuance of any stop order by the
SEC  suspending  the  effectiveness  of  such  Registration   Statement  or  the
initiation or  threatening  of any  proceeding for that purpose and promptly use
its best  efforts to  prevent  the  issuance  of any stop order or to obtain its
withdrawal if such stop order should be issued.

                        (vii)  Prepare and file with the SEC,  promptly upon the
request  of any of the  Shareholder,  any  amendments  or  supplements  to  such
Registration  Statement or Prospectus  which,  in the opinion of counsel for the
Shareholder,  is required under the Securities Act or the rules and  regulations
there  under  in  connection  with  the   distribution  of  the  Shares  by  the
Shareholder.

                        (viii) Use its best  efforts to  register or qualify the
Shares covered by each  Registration  Statement  under such state  securities or
blue sky laws of such  jurisdictions as the Shareholder and any underwriters may
reasonably  request;  provided,  that IVP shall not be  required  to execute any
general  consent to service of process or to qualify to do business as a foreign
corporation  in any  jurisdiction  where  it is not so  qualified  and  provided
further that any such  qualification or registration shall not exceed $5,000 for
any one jurisdiction.

                  (d) IVP may  require  the  Shareholder  to furnish to IVP such
information  regarding  the  distribution  of  the  Shares  and  the  beneficial
ownership  of  the  Shares  as is  required  by  law  to  be  disclosed  in  the
Registration  Statement and IVP may exclude from such registration Shares of any
holder who unreasonably  fails to furnish such  information  within a reasonable
time after receiving such request.

                                       6
<PAGE>

                  (e) If the  Registration  Statement  refers  to any  holder of
Shares by name or otherwise as the holder of any  securities  of IVP,  then such
holder of Shares  shall have the right to  require  (if such  reference  to such
holder of Shares by name or otherwise is not required by the  Securities  Act or
any similar Federal statute then in force) the deletion of the reference to such
holder in any  amendment or supplement to the  Registration  Statement  filed or
prepared subsequent to the time that such reference ceases to be required.

                  (f) Each holder of Shares  agrees by its  acquisition  of such
Shares  that it will  not  offer  or sell  any  Shares  under  the  Registration
Statement  until  it has  received  copies  of the  prospectus  included  in the
Registration  Statement as then amended or supplemented and notice from IVP that
such  Registration  Statement  and any  post-effective  amendments  thereto have
become  effective and that such holder will comply with the prospectus  delivery
requirements  of the Securities Act as applicable to it in connection with sales
of Shares pursuant to the Registration Statement.

                  (g) Each holder of Shares  agrees by its  acquisition  of such
Shares that, upon receipt of a notice from IVP of the occurrence of any event of
the kind described in this Section 5.01 such holder will  forthwith  discontinue
disposition  of  Shares  until  such  holder's  receipt  of  the  copies  of the
supplemented  prospectus and/or amended Registration  Statement,  or until it is
advised  in  writing  by IVP that the use of the  applicable  prospectus  may be
resumed.

                  (h) Expenses. All expenses incident to IVP's performance of or
compliance  with  this  undertaking  in this  Section  2.04,  including  without
limitation all registration and filing fees (other than  registration and filing
fees in excess of $5,000 imposed by state securities or blue sky laws), printing
expenses, messenger and delivery expenses, and fees and disbursements of counsel
for  IVP  and  all  independent   certified  public  accountants,   underwriters
(excluding  discounts and  commissions)  and other persons  retained by IVP (all
such expenses  being herein called  "Registration  Expenses"),  will be borne by
IVP. IVP will,  in all events,  pay its internal  expenses  (including,  without
limitation,  all salaries and expenses of its officers and employees  performing
legal or accounting duties),  the expense of any annual audit and the expense of
any liability  insurance.  IVP shall not be  responsible  for any  commission or
selling  expenses  incurred  by the  Shareholder  of Shares,  fees of counsel or
accountants  retained  by  Shareholder  or of any  other  fees not  specifically
referenced above.

                                       7
<PAGE>

                  (i) Reporting  Requirements Under the Securities  Exchange Act
of 1934. IVP shall timely file all such information,  documents,  and reports as
the SEC may  require  or  prescribe  under  either  Section  13 or  15(d) of the
Exchange  Act.  IVP shall,  whenever  requested by the  Shareholder,  notify the
Shareholder,  in  writing  whether  IVP  has,  as of the date  specified  by the
Shareholder,  complied with the Exchange Act reporting  requirements to which it
is  subject  for a period  prior  to such  date as  shall  be  specified  by the
Shareholder.  IVP  acknowledges and agrees that the purposes of the requirements
contained in this Section  2.04(i) are: (I) to enable the  Shareholder to comply
with the current public  information  requirement  contained in Paragraph (c) of
Rule 144 under the Act should the Shareholder ever wish to dispose of any of the
Shares without  registration  under the Securities Act in reliance upon Rule 144
(or any equivalent successor provision);  and (II) to qualify IVP for the use of
registration  statements  on Form S-3,  or its  equivalent  successor  form,  in
connection with secondary  distributions of securities of IVP. In addition,  IVP
shall take such other measures and file such other information,  documents,  and
reports  as  shall  hereafter  be  required  by the  SEC as a  condition  to the
availability  of Rule 144 under the Securities Act (or any equivalent  successor
provision), including, without limitation, using its best efforts to assure that
there shall be available at all times adequate public  information  with respect
to IVP and the IVP Stock.  The  obligation  to make  available  adequate  public
information  and  otherwise  take  such  measures   necessary  to  maintain  the
availability  of Rule 144 shall  continue  in the event that IVP shall  cease to
become subject to the filing  requirements of Section 13 or Section 15(d) of the
Exchange Act.

                  (j) Indemnification

                        (i)  Indemnification by IVP. IVP shall,  notwithstanding
any termination of this Agreement,  indemnify and hold harmless each Shareholder
to the fullest extent  permitted by applicable law, from and against any and all
losses, claims, damages, liabilities,  settlements, judgments, costs (including,
without  limitation,  costs of preparation and reasonable  attorneys'  fees) and
expenses (collectively,  "Losses"),  incurred, arising out of or relating to any
untrue  or  alleged  untrue  statement  of a  material  fact  contained  in  the
Registration   Statement,   or  any   prospectus   forming  a  part  thereof  (a
"Prospectus"),  or in any amendment or supplement thereto, or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein  (in the case of any  Prospectus  or form of  prospectus  or
supplement  thereto,  in light of the circumstances  under which they were made)
not  misleading,  except to the extent that such untrue  statements or omissions
are based  solely upon  information  regarding  such  Shareholder  furnished  in
writing to IVP by or on behalf of such Shareholder expressly for use therein, or
to the  extent  that  such  information  relates  to  such  Shareholder  or such
Shareholder's  proposed  method of  distribution  of Shares and was reviewed and
expressly  approved  in writing  by such  Shareholder  expressly  for use in the
Registration  Statement,  such  Prospectus  or such form of prospectus or in any
amendment or supplement thereto, provided,  however, that under no circumstances
shall any Shareholder  who is an officer or director of IVP and  participated in
the preparation and filing of any such Registration  Statement and Prospectus be
relieved from primary liability under the Securities Act or Securities  Exchange
Act for material  misstatements or omissions in said  Registration  Statement or
Prospectus. IVP shall notify the Shareholder promptly of the institution, threat
or assertion of any action, claim, suit, investigation or proceeding (including,
without  limitation,   an  investigation  or  partial  proceeding,   such  as  a
deposition),   whether  commenced  or  threatened   (herein  referred  to  as  a
"Proceeding")  of  which  IVP is  aware  in  connection  with  the  transactions
contemplated by this Agreement.

<PAGE>

                        (ii)   Indemnification   by   the   Shareholder.    Each
Shareholder shall,  severally and not jointly,  indemnify and hold harmless IVP,
its  directors,  officers,  agents and  employees,  each Person who controls IVP
(within  the meaning of Section 15 of the  Securities  Act and Section 20 of the
Securities  Exchange  Act), to the fullest extent  permitted by applicable  law,
from and against all Losses (as determined by a court of competent  jurisdiction
in a final  judgment not subject to appeal or review)  arising  solely out of or
based  solely upon any untrue  statement  of a material  fact  contained  in the
Registration Statement,  any Prospectus,  or any form of prospectus,  or arising
solely out of or based solely upon any omission of a material  fact  required to
be stated therein or necessary to make the statements  therein not misleading to
the  extent,  that  such  untrue  statement  or  omission  is  contained  in any
information so furnished in writing by such  Shareholder to IVP specifically for
inclusion in the Registration Statement or such Prospectus or to the extent that
such  information  relates to such  Shareholder or such  Shareholder's  proposed
method of  distribution  of Shares and was  reviewed and  expressly  approved in
writing by such  Shareholder  expressly for use in the  Registration  Statement,
such Prospectus or such form of Prospectus and as otherwise  provided in Section
2.04(j)(i), above.

                        (iii)  Conduct of  Indemnification  Proceedings.  If any
Proceeding shall be brought or asserted against any person entitled to indemnity
hereunder (an "Indemnified Party"), such Indemnified Party promptly shall notify
the person from whom indemnity is sought (the "Indemnifying  Party") in writing,
and the  Indemnifying  Party shall  assume the defense  thereof,  including  the
employment of counsel  reasonably  satisfactory to the Indemnified Party and the
payment of all fees and expenses  incurred in connection  with defense  thereof;
provided,  that the failure of any  Indemnified  Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this  Agreement,  except  (and  only) to the  extent  that it  shall be  finally
determined  by a court of competent  jurisdiction  (which  determination  is not
subject to appeal or further  review) that such failure  shall have  proximately
and materially adversely prejudiced the Indemnifying Party.

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense  thereof,  but the fees
and expenses of such counsel shall be at the expense of such  Indemnified  Party
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses;  or (2) the Indemnifying  Party shall have failed promptly to
assume  the  defense  of  such  Proceeding  and  to  employ  counsel  reasonably
satisfactory to such Indemnified Party in any such Proceeding;  or (3) the named
parties to any such Proceeding  (including any impleaded  parties)  include both
such Indemnified  Party and the Indemnifying  Party, and such Indemnified  Party
shall have been  advised by counsel  that a conflict  of  interest  is likely to
exist if the same  counsel  were to  represent  such  Indemnified  Party and the
Indemnifying  Party (in which  case,  if such  Indemnified  Party  notifies  the
Indemnifying  Party in writing that it elects to employ separate  counsel at the
expense of the Indemnifying  Party,  the  Indemnifying  Party shall not have the
right to assume the defense  thereof and such counsel shall be at the expense of
the  Indemnifying  Party).  The  Indemnifying  Party shall not be liable for any
settlement of any such Proceeding  effected without its written  consent,  which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party,  unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

            All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent  incurred in connection  with  investigating  or
preparing  to defend  such  Proceeding  in a manner not  inconsistent  with this
Section) shall be paid to the Indemnified  Party,  as incurred,  within ten (10)
business days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification  hereunder;  provided,  that the Indemnifying  Party may require
such  Indemnified  Party to undertake to reimburse all such fees and expenses to
the extent it is finally  judicially  determined that such Indemnified  Party is
not entitled to indemnification hereunder).

                  (iv)  Contribution.  If  a  claim  for  indemnification  under
Section 2.04(j)(i) or 2.04(j)(ii) is unavailable to an Indemnified Party because
of  a  failure  or  refusal  of  a   governmental   authority  to  enforce  such
indemnification  in  accordance  with its terms (by  reason of public  policy or
otherwise),   then  each  Indemnifying  Party,  in  lieu  of  indemnifying  such
Indemnified  Party,  shall  contribute  to the  amount  paid or  payable by such
Indemnified  Party  as a  result  of  such  Losses,  in  such  proportion  as is
appropriate  to  reflect  the  relative  fault  of the  Indemnifying  Party  and
Indemnified  Party in connection with the actions,  statements or omissions that
resulted in such Losses as well as any other relevant equitable  considerations.
The relative fault of such  Indemnifying  Party and  Indemnified  Party shall be
determined by reference to, among other things,  whether any action in question,
including any untrue or alleged untrue  statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information  supplied by, such Indemnifying  Party or Indemnified Party, and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct or prevent  such  action,  statement  or  omission.  The amount  paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 2.04(j)(ii),  any reasonable  attorneys'
or other  reasonable fees or expenses  incurred by such party in connection with
any  Proceeding  to the extent such party would have been  indemnified  for such
fees  or  expenses  if the  indemnification  provided  for in this  Section  was
available to such party in accordance with its terms.

            The parties  hereto agree that it would not be just and equitable if
contribution  pursuant to this Section  2.04(j)(iv)  were determined by pro rata
allocation or by any other method of allocation  that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding  the  provisions of this Section  2.04(j)(iv),  the  Shareholder
shall not be required to contribute,  in the aggregate,  any amount in excess of
the amount of proceeds actually received by the Shareholder from the sale of the
Shares. No person guilty of fraudulent  misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution  from any
Person who was not guilty of such fraudulent misrepresentation.

            The indemnity and contribution  agreements contained in this Section
are in addition to any liability that the  Indemnifying  Parties may have to the
Indemnified Parties.

                                       11
<PAGE>

                  (v) The  obligations  of IVP and the  Shareholder  under  this
Section  2.04(j)  shall  survive the  completion  of any offering of Shares in a
registration statement under this Section 2.04, and otherwise.

            2.05. Assignment of Registration Rights. The rights of a Shareholder
to have the Shares  registered  hereunder shall be  automatically  assignable by
such Shareholder to any assignee or transferee of all or a portion of the Shares
without  the  consent  of IVP but only (a) after  such time as Shares  have been
released  from Escrow and vested  with a  Shareholder;  (b) if such  Shareholder
agrees in writing with the  transferee or assignee to assign such rights,  and a
copy of such  agreement is furnished to IVP within a reasonable  time after such
assignment,  (c) if IVP is,  within a  reasonable  time after such  transfer  or
assignment,  furnished  with written  notice of (i) the name and address of such
transferee  or  assignee,   and  (ii)  the  securities   with  respect  to  such
registration rights are being transferred or assigned,  and (d) if, at or before
the time IVP  receives  the written  notice  contemplated  by clause (c) of this
Section,  the  transferee or assignee  agrees in writing with IVP to be bound by
all of the provisions of this Agreement. The rights to assignment shall apply to
the Shareholder' (and to subsequent) successors and assigns.

            2.06.  Confidentiality.  Each party  hereto will hold and will cause
its consultants and advisors to hold in strict  confidence,  unless compelled to
disclose  by  judicial  or  administrative  process  or, in the  opinion  of its
counsel, by other requirements of law, all documents and information  concerning
the other  party  furnished  it by such other  party or its  representatives  in
connection with the transactions  contemplated by this Agreement  (except to the
extent that such  information can be shown to have been (i) previously  known by
the party to which it was furnished,  (ii) in the public domain through no fault
of such party, or (iii) later lawfully  acquired from other sources by the party
to which it was  furnished),  and each party will not release or  disclose  such
information  to any other  person,  except its  auditors,  attorneys,  financial
advisors,  bankers and other  consultants  and advisors in connection  with this
Agreement.   If  the  transactions   contemplated  by  this  Agreement  are  not
consummated,  such  confidence  shall be  maintained  except to the extent  such
information  comes into the public domain through no fault of the party required
to  hold  it in  confidence,  and  such  information  shall  not be  used to the
detriment of, or in relation to any  investment in, the other party and all such
documents  (including  copies  thereof)  shall be  returned  to the other  party
immediately  upon the written  request of such other party.  Each party shall be
deemed  to  have  satisfied  its  obligation  to hold  confidential  information
concerning  or supplied by the other party if it  exercises  the same care as it
takes to preserve confidentiality for its own similar information.
