      PLEDGE

       

      Section
2.1 Pledge.  As
security for the payment and performance of the Secured Obligations and MedPro
Obligations, MedPro hereby pledges, grants, assigns, hypothecates, transfers and
delivers to the Secured Party, its successors and assigns, for its benefit and
the behalf of Noteholders, a continuing first priority security interest in all
of MedPro’s right, title and interest in, to and under the following property,
whether now owned or hereafter acquired (the “Collateral”):

       

      (a) all
of MedPro’s Equity Interests in the Issuer, whether now owned or acquired in the
future, and all certificates, agreements or other instruments, if any,
representing such Equity Interests (the “Pledged
Equity”);

       

      (b) the
right to receive all monies and property representing a distribution in respect
of the Pledged Equity, whether by way of dividend, redemption, liquidation
payments, repurchase or otherwise;

       

      (c) all
books, records, ledger cards, files, correspondence, computer programs, tapes,
disks and related data processing software that at any time evidence or contain
information relating to any of the Collateral or are otherwise necessary or
helpful in the collection thereof or realization thereupon;

       

      (d) all
Proceeds, products and accessions of every nature of and to the Pledged Equity
and any of the foregoing, including all shares, securities, rights, monies or
other property accruing, offered or issued at any time by way of redemption,
conversion, exchange, substitution, preference, option or otherwise in respect
of the Pledged Equity;

       

      TO HAVE
AND TO HOLD the Collateral, together with all right, title, interest, powers,
privileges and preferences pertaining or incidental thereto, unto the Secured
Party, its successors and assigns, forever, subject to the terms and conditions
set forth herein.

       

      Section
2.2 Dividends and
Distributions.  So long as no Default or Event of Default has
occurred and is continuing or would be caused thereby, subject to Section 3.3
hereof, MedPro may receive and retain any dividends and other distributions on
the Pledged Equity from distributions it may receive from the Issuer in
accordance with the provisions of Section 3.7(a) of the Indenture, and subject
to Section 3.3 hereof, all such dividends and other distributions shall not
constitute Collateral.  If a Default or an Event of Default has
occurred and is continuing or would be caused thereby, MedPro shall not be
entitled to receive any subsequent dividends or other distributions on the
Pledged Equity and, unless otherwise agreed by the Secured Party at the
Direction of Noteholders of a majority of the Outstanding Principal Balance of
the Notes, all such subsequent dividends and other distributions shall
constitute Collateral.  For the avoidance of doubt, MedPro’s right to
receive and retain any dividends and other distributions does not in any way
restrict the rights of the Secured Party to exercise its rights under Section

recapitalization, reclassification or increase or reduction of capital (whether

representations and warranties shall survive the execution and delivery hereof)
to the Trustee and the Noteholders as follows:

       

      (a)
MedPro has been duly organized and is validly existing as a corporation in good
standing under the laws of the State of Nevada and has all licenses, permits,
franchises and governmental authorizations necessary to carry on its business as
now being conducted and shall appoint and employ agents or attorneys in each
jurisdiction where it shall be necessary to take action under this
Agreement.  MedPro is duly licensed or qualified to do business as a
foreign corporation in good standing in each jurisdiction in which such
qualification is required by law.  MedPro has the full corporate power
and authority to own the property it purports to own and to carry on its
business as presently conducted and as proposed to be conducted.

       

      
        
           

        

        
          5

          
            

          

        

        
           

        

      

       

      (b)
MedPro is the sole legal and beneficial owner of the Collateral free and clear
of any Encumbrance other than the Encumbrance created pursuant to this Agreement
and the Indenture.  No security agreement, financing statement or
other public notice with respect to all or any part of the Collateral is on file
or of record in any public office, except such as may have been filed in favor
of the Secured Party pursuant to this Agreement and the Indenture.

       

      (c) The
consummation of the transactions contemplated hereby has been duly and validly
authorized by MedPro.  MedPro has full corporate power to execute and
deliver this Agreement and to perform its obligations hereunder and to pledge
all the Collateral pursuant to this Agreement.  This Agreement has
been duly authorized, executed and delivered by MedPro.  This
Agreement constitutes a legal, valid and binding obligation of MedPro
enforceable against MedPro in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency, moratorium
or other similar laws affecting creditors’ rights generally and except as
enforceability may be limited by general principles of equity (whether
considered in a suit at law or in equity).  All requisite corporate
action has been taken by MedPro to make this Agreement valid and binding upon
MedPro.

       

      (d) No
consent of any other party (including, without limitation, shareholders,
directors or creditors of MedPro) and no government approval is required which
has not been obtained (i) for the execution, delivery and performance by MedPro
of this Agreement and each other Transaction Document to which it is a party,
(ii) for the pledge by MedPro of the Collateral pursuant to this Agreement or
(iii) for the exercise by the Secured Party of the rights provided for in this
Agreement or the remedies in respect of the Collateral pursuant to this
Agreement (except as may be required (x) in connection with any disposition of
all or any part of the Collateral under any laws affecting the offering and sale
of securities generally, and (y) under applicable federal and state laws, rules
and regulations and applicable interpretations thereof providing for the
supervision or regulation of the banking or trust businesses generally and
applicable to the Secured Party.

       

      (e) The
execution and delivery of this Agreement concurrently with the delivery to the
Secured Party of the certificates and other items contemplated by Section 3.1
and the taking of the actions described in Section 3.3 constitute “control” of
the Pledged Equity described in Section 8-106(b) of the UCC and create a valid
security interest in the Collateral securing the Secured Obligations, and MedPro
has done such other acts, if any, reasonably requested by the Secured Party to
perfect the security interest in the Collateral granted
hereunder (including permitting the Trustee to file any appropriate UCC
financing statement against MedPro).

       

      (f) The
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated by this Agreement do not (i) violate the
provisions of the articles of incorporation or bylaws (or equivalents thereof)
of MedPro, (ii) violate the provisions of any law (including, without
limitation, any usury law), regulation or order of any government authority
applicable to MedPro, (iii) result in a breach of, or constitute a default
under, any material agreement relating to the management or affairs of MedPro,
or any indenture or loan agreement or any other similar agreement, lease or
instrument to which MedPro is a party or by which MedPro or any of its
properties may be bound (which default or breach has not been permanently waived
by the other party to such document) or (iv) result in or create any Encumbrance
[(other than Permitted Encumbrances)] under, or require any consent which has
not been obtained under, any indenture (including the Indenture) or loan
agreement or any other material agreement, instrument or document or the
provisions of any order, writ, judgment, injunction, decree, determination or
award of any government authority, binding upon MedPro, the Collateral or any of
its properties.

are no proceedings and there is no action, suit or proceeding at law or in
equity or by or before any government authority, arbitral tribunal or other body
now pending against MedPro or, to the best knowledge of MedPro, threatened
against MedPro which questions the validity or legality of or seeks damages in
connection with this Agreement or which seeks to prevent the consummation of any
of the transactions contemplated by this Agreement.

       

      (h) All
of the Pledged Equity has been duly authorized and validly issued by the Issuer
and is fully paid and non-assessable.

further instruments and documents, and take all further action, that may be
necessary or desirable in the reasonable discretion of the Secured Party, in
order to perfect the security interest in the Collateral and to carry out the
provisions of this Agreement or to enable the Secured Party to exercise and
enforce its rights and remedies hereunder with respect to any
Collateral.  MedPro also agrees that, at any time and from time to
time, at the MedPro's expense and upon the request of the Secured Party at the
Direction of Noteholders of a majority of the Outstanding Principal Balance of
the Notes, MedPro will file (or cause to be filed) such UCC financing statements
or continuation statements, or amendments thereto, and such other instruments or
notices as may be necessary or that the Secured Party may reasonably request at
the Direction of Noteholders of a majority of the Outstanding Principal Balance
of the Notes in order to perfect and preserve the security interests and other
rights granted or purported to be granted to the Secured Party hereby. With
respect to the foregoing and the grant of the security interest hereunder,
MedPro hereby authorizes the Secured Party to file one or more UCC financing
statements or continuation statements, and amendments thereto, relative to all
or any part of the Collateral without the signature of MedPro where permitted by
law.  MedPro agrees that a carbon, photographic or other reproduction
of this Agreement or any UCC financing statement covering the Collateral or any
part thereof shall be sufficient as a UCC financing statement where permitted by
law

being understood that no such request need be given after the occurrence and

not obligated to) itself perform, or cause performance of, such agreement, in
which case the reasonable expenses of the Secured Party, including the fees and
expenses of its counsel, incurred in connection therewith shall be payable by
MedPro under Section 11.1.

consent of the Secured Party, it will not (a) sell or otherwise dispose of the

create or permit to exist any Encumbrance upon or with respect to any of the
Collateral or any interest therein.

       

      Section
6.2 Notices.  MedPro
shall promptly give the Secured Party copies of all notices and other
communications received by MedPro with respect to any Collateral registered in
the name of MedPro.

       

      Section
6.3 Voting
Rights.  Notwithstanding anything to the contrary in this
Agreement or any other Transaction Document, if no Event of Default has occurred
and is continuing or would be caused thereby, MedPro may exercise any and all
voting and consensual powers pertaining to the Collateral or any part thereof
for any purpose not inconsistent with the terms of this Agreement or other
Transaction Documents; provided; however, that MedPro
shall not exercise or refrain from exercising any such right if Secured Party or
Noteholders representing a majority of the Outstanding Principal Balance of the
Notes shall have notified MedPro that, in their respective judgment, such action
would have a material adverse effect on the value of the Collateral or any part
thereof.  If an Event of Default has occurred and is continuing,
MedPro shall not be entitled to exercise any of the powers described in the
preceding sentence, which shall be exercised exclusively by the Secured
Party.  In order to permit Secured Party to exercise the voting and
other consensual rights that it may be entitled to exercise pursuant to this
Section 6.3 and to receive all dividends and other distributions which it may be
entitled to receive under this Agreement, (i) MedPro shall promptly execute
and deliver (or cause to be executed and delivered) to Secured Party all such
proxies, dividend payment orders and other instruments as Secured Party may from
time to time reasonably request and (ii) without limiting the effect of the
immediately preceding clause (i), MedPro hereby grants to Secured Party an
irrevocable proxy to vote the Pledged Equity and to exercise all other rights,
powers, privileges and remedies to which a holder of the Pledged Equity would be
entitled (including, without limitation, giving or withholding written consents
of holders of Equity Interests, calling special meetings of holders of Equity
Interests and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Equity on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Equity or any officer or agent
thereof), upon the occurrence of an Event of Default and which proxy shall only
terminate upon the payment in full of the Secured Obligations.

       Notwithstanding
the foregoing, upon the occurrence and during the continuance of an Event of
Default, the Secured Party will have the right to instruct the Independent
Manager to exercise the powers and authority granted to the Independent Manager
pursuant to the limited liability company agreement of the Issuer to exercise
any and all rights and options of the Issuer in relation to the LLC Agreement to
enforce performance by the other parties thereto of their obligations
thereunder. If the Independent Member elects not to exercise such rights and
options notwithstanding the provision by the Noteholders of reasonable indemnity
thereto, then the Secured Party will have the right to terminate the Independent
Manager and to appoint a successor Independent Manager of the Issuer to exercise
such rights and options. MedPro agrees to cooperate with the Secured Party to
cause such successor Independent Manager to succeed the terminated Independent
Manager, to be a manager of the Issuer, and to obtain and enjoy to the exclusion
of the terminated Independent Manager all interests, powers, rights and
authority previously owned, possessed or enjoyed by the terminated Independent
Manager pursuant to the limited liability company agreement of the Issuer. The
Secured Party will not be required to deliver any such instruction to the
Independent Manager or to terminate the Independent Manager or appoint any
successor Independent Manager unless instructed to do so by Direction of
Noteholders of a majority of the Outstanding Principal Balance of the Notes,
will only do so as specified in such Direction, and will be entitled to be
indemnified in full and held harmless by the Noteholders in connection with its
delivery of any such instruction or any such termination or
appointment.

       

      Section
6.4 Equity
Interests.  MedPro agrees that it will not accept any Equity
Interests or other equity ownership interests, any rights or options to acquire
any Equity Interests or other equity ownership interests or other securities,
each in addition to or in substitution for the Collateral, without prior written
consent of the Secured Party.

       

      Section
6.5 Legal
Subsistence.  MedPro shall preserve and maintain (a) its legal
subsistence as a corporation in good standing under the laws of the State of
Nevada and (b) its qualification to do business in every jurisdiction where the
ownership of its properties and the nature of its business require them to be so
qualified and where the failure to be so qualified could have a material adverse
effect on the security interest created by this Agreement; except as expressly
provided in Section 6.2(j) of the Purchase and Sale Agreement.

       

      Section
6.6 Compliance with
Laws.  MedPro shall comply with all laws, and obtain, maintain
and comply with all government approvals as shall now or hereafter be necessary
under applicable law, rule, or regulation, in each case, in connection with the
making and performance by MedPro of any provision of this
Agreement.

       

      Section
6.7 Taxes.  MedPro
shall pay and discharge all taxes, assessments and governmental charges or
levies imposed on it or on its incomes or profits or on any of its properties,
in each case, prior to the date on which penalties attach thereto, and all
lawful claims that, if unpaid, could reasonably be expected to become an
Encumbrance (other than a Permitted Encumbrance) upon the Collateral, unless
such matters are being challenged by MedPro in good faith by appropriate
proceedings promptly instituted and diligently conducted, so long as (a)
appropriate reserves shall have been made therefor and (b) in the case of a
charge or claim that has become an Encumbrance (other than a Permitted
Encumbrance), such proceedings conclusively operate to stay such charge or
claim. MedPro will promptly pay or cause to be paid any valid, final judgment
enforcing any such tax, assessment, charge, levy or claim and cause the same to
be satisfied of record.  MedPro will promptly pay or cause to be paid
any valid, final judgment enforcing any such tax, assessment, charge, levy or
claim and cause the same to be satisfied of record.

shall not, without the prior written consent of the Secured Party, agree to or
permit (a) any amendment, supplement or modification of, or waiver with respect
to, any of the provisions of any of its organizational documents, if any such
amendment, supplement, modification or waiver could result in an adverse change
in the value of the Collateral or the rights of the Secured Party, or (b) the
cancellation or termination of any of its organizational documents.

       

      Section
6.9 No
Liquidation.  Without the prior written direction by the

Party, in order to satisfy the Secured Obligations pursuant to the direction of
the Secured Party.

       

      Section

Claims.  Subject to Section 2.2, MedPro shall not claim
payment, whether directly or by set-off, lien, counterclaim or otherwise, of any
amount that may be or has become due to MedPro from the Issuer other than
Expenses and Servicing Fees in accordance with Section 3.7(a) of the Indenture
and all royalties payable to MedPro to be held in trust or escrow pursuant to
Section 3.7(b) of the Indenture until all of the Secured Obligations have been

      REASONABLE
CARE

       

      Section
8.1 Reasonable
Care.  The Secured Party shall be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession if the Collateral is accorded treatment substantially equivalent to
that which the Secured Party accords its own property of the type of which the
Collateral consists, it being understood that the Secured Party shall have no
responsibility for (a) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Collateral, whether or not the Secured Party has or is deemed to have knowledge
of such matters, or (b) taking any necessary steps to preserve rights against
any parties with respect to any Collateral.

guarantee therefor, or any part thereof, or for any delay in so doing nor shall
it be under any obligation to take any action whatsoever with regard

      REMEDIES UPON EVENT OF
DEFAULT

       

      Section
10.1 Remedies Upon
Event of Default.  If an Event of Default shall have occurred
and be continuing:

       

      (a) The
Secured Party may exercise the power of attorney described in Section 7.1 with
respect to the Collateral and any of the certificates or other instruments
delivered pursuant to Section 3.1, and may sign, complete and deliver all
transfers, proxies and letters of resignation and do all acts and things that
the Secured Party may in its absolute discretion specify to enable or assist the
Secured Party to perfect or improve its security over the Equity Interests, to
vest ownership of the Equity Interests in the Secured Party or its nominee, to
provide that the Secured Party is registered as the holder of the Equity
Interests, to exercise any rights or powers attaching to the Equity Interests,
to sell the Equity Interests or otherwise to enforce any of the rights of the
Secured Party under this Agreement.

       

      (b) The
Secured Party may exercise in respect of the Collateral, in addition to other
rights and remedies provided for herein or otherwise available to it, all the
rights and remedies of a secured party on default under the UCC then in effect
in any applicable jurisdiction, and the Secured Party may also in its sole
discretion, without notice except as specified below or except as required by
mandatory provisions of law, sell the Collateral or any part thereof in one or
more parcels at public or private sale or at any of the Secured Party’s offices
or elsewhere, for cash, on credit or for future delivery, and at such price or
prices and upon such other terms as the Secured Party may reasonably deem
commercially reasonable, irrespective of the impact of any such sales on the
market price of the Collateral at any such sale.  Each purchaser at
any such sale shall hold the property, sold absolutely, free from any claim or
right on the part of MedPro, and MedPro hereby waives (to the extent permitted
by law) all rights of redemption, stay and/or appraisal which it now has or may
at any time in the future have under any rule of law or statute now existing or
hereafter enacted.  MedPro agrees that, to the extent notice of sale
shall be required by law, at least ten days’ notice to MedPro of the time and
place of any public sale or the time after which any private sale is to be made
shall constitute reasonable notification.  The Secured Party shall not
be obligated to make any sale of Collateral regardless of notice of sale having
been given.  The Secured Party may adjourn any public or private sale
from time to time by announcement at the time and place fixed therefor, and such
sale may, without further notice, be made at the time and place to which it was
so adjourned.  The Secured Party shall incur no liability as a result
of the sale of the Collateral, or any part thereof, at any public or private
sale.  MedPro hereby waives any claims against the Secured Party
arising by reason of the fact that the price at which any Collateral may have
been sold at such a private sale was less than the price which might have been
obtained at a public sale, even if the Secured Party accepts the first offer
received and does not offer such Collateral to more than one
offeree.

       

      (c)
MedPro recognizes that the Secured Party may elect in its sole discretion to
sell all or a part of the Collateral to one or more purchasers in privately
negotiated transactions in which the purchasers will be obligated to agree,
among other things, to acquire the Collateral for their own account, for
investment and not with a view to the distribution or resale
thereof.  MedPro acknowledges that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
(including, without limitation, a public offering made pursuant to a
registration statement under the Securities Act), and MedPro and the Secured
Party agree that the mere fact that such private sales were private sales
individually negotiated, does not mean that such private sales were note made in
a commercially reasonably manner, and that the Secured Party has no obligation
to engage in public sales or to delay the sale of any Collateral to permit the
issuer thereof to register the Collateral in connection with a public sale
requiring registration under the Securities Act.

      (d) Any
cash held by the Secured Party as Collateral and all cash proceeds received by
the Secured Party in respect of any sale of, collection from or other
realization upon all or any part of the Collateral shall, as soon as reasonably
practicable, be applied (after payment of any amounts payable to the Secured
Party pursuant to Section 11.1) by the Secured Party, first, to the payment
of the costs and expenses of such sale, collection or other realization, if any,
including reasonable out-of-pocket costs and expenses of the Secured Party
(including the reasonable fees and out-of-pocket expenses of its counsel), and
all reasonable expenses, liabilities and advances made or incurred by the
Secured Party in connection therewith to the extent not paid by MedPro pursuant
to Section 11.1, second, to the
payment of the Secured Obligations in accordance with the terms of the Indenture
and, third, all
remaining amounts shall promptly be paid to MedPro or its successors or
assigns.

       

      (e) The
Secured Party may by writing without notice to MedPro appoint one or more
persons as the Secured Party deems fit to be a receiver in relation to the
Collateral. Where the Secured Party appoints two or more persons as such
receiver, such receivers may act jointly or independently. With respect to the
enforcement of this Agreement, such receiver may sell, charge or otherwise
dispose of the Collateral, exercise any powers, discretion, voting or other
rights or entitlements in relation to the Collateral and generally carry out any
other action that such receiver may in such receiver's sole discretion deem
necessary in relation to the enforcement of this Agreement. Such receiver shall
have, in addition to the other powers set forth in this Section 10.1(e), the
power to:

       

      (i) take
possession of, collect and get in the Collateral and, for that purpose, take
such proceedings as may seem to such receiver to be expedient;

       

      (ii)
raise or borrow money and grant security therefor over the
Collateral;

       

      (iii)
appoint an attorney or accountant or other professionally qualified person to
assist such receiver in the performance of such receiver's
functions;

       

      (iv)
bring or defend any action or other legal proceeding in the name of and on
behalf of MedPro in respect of the Collateral;

       

      (v) do
all acts and execute in the name and on behalf of MedPro any document or deed in
respect of the Collateral;

       

      (vi) make
any payment that is necessary or incidental to the performance of such
receiver's functions;

      (vii)
make any arrangement or compromise on behalf of MedPro in respect of the
Collateral;

       

      (viii)
rank and claim in the insolvency or liquidation of the Issuer and receive
dividends and accede to agreements for the creditors of the Issuer;

       

      (ix)
present or defend a petition for the winding up of the Issuer; and

       

      (x) do
all other things incidental to the exercise of the foregoing
powers.

       

      (f)
MedPro agrees that:

       

      (i) in
any sale of any of the Collateral whenever an Event of Default shall have
occurred and be continuing, the Secured Party is hereby authorized to comply
with any limitation or restriction in connection with such sale as it may be
advised by counsel is necessary in order to:

       

          (A)
avoid any violation of law(including compliance with such procedures as may
restrict the number of prospective bidders and purchasers, require that such
prospective bidders and purchasers have certain qualifications and restrict such
prospective bidders and purchasers to Persons who will represent and agree that
they are purchasing for their own account for investment and not with a view to
the distribution or resale of such Collateral); or

       

          (B)
obtain any required approval of the sale or of the purchaser by any governmental
authority or official; and

       

      (ii) such
compliance shall not result in such sale being considered or deemed not to have
been made in a commercially reasonable manner, nor shall the Secured Party be
liable or accountable to MedPro for any discount allowed by the reason of the
fact that such Collateral is sold in compliance with any such limitation or
restriction.
