in any other reasonable manner that the Trustee deems sufficient.

       

      (c)           In
determining whether the Noteholders have given any direction, consent, request,
demand, authorization, notice, waiver or other Act (a “Direction”) under
this Indenture, Notes owned by the Issuer, MedPro or any Affiliate of any such
Person shall be disregarded and deemed not to be Outstanding for purposes of any
such determination. In determining whether the Trustee shall be protected in
relying upon any such Direction, only Notes that a Responsible Officer of the
Trustee actually knows to be so owned shall be so disregarded. Notwithstanding
the foregoing, (i) if any such Person owns 100% of the Notes Outstanding, such
Notes shall not be so disregarded as aforesaid, and (ii) if any amount of Notes
so owned by any such Person have been pledged in good faith, such Notes shall
not be disregarded as aforesaid if the pledgee establishes to the satisfaction
of the Trustee the pledgee’s right so to act with respect to such Notes and that
the pledgee is not the Issuer, MedPro or an Affiliate of any such
Person.

       

      (d)           The
Issuer may, at its option, by delivery of Officer’s Certificate(s) to the
Trustee, set a record date other than the Record Date to determine the
Noteholders in respect of the Notes entitled to give any Direction in respect of
such Notes, and the Trustee may do so when acting in accordance with Section
6.2. Such record date shall be the record date specified in such Officer’s
Certificate or set by the Trustee when acting in accordance with Section 6.2,
which shall be a date not more than 30 days prior to the first solicitation of
Noteholders in connection therewith. If such a record date is fixed, such
Direction may be given before or after such record date, but only the
Noteholders at the close of business on such record date shall be deemed to be
Noteholders for the purposes of determining whether Noteholders of the requisite
proportion of Outstanding Notes have authorized, agreed or consented to such
Direction, and for that purpose the Outstanding Notes shall be computed as of
such record date; provided, that no
such Direction by the Noteholders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than one year after the record date.

       

      (e)           Any
Direction or other action by the Noteholder of any Note shall bind the
Noteholder of every Note issued upon the transfer thereof, in exchange therefor
or in lieu thereof, whether or not notation of such action is made upon such
Note, and any Direction or other action by the Beneficial Holder of any
Beneficial Interest in any Note shall bind any transferee of such Beneficial
Interest.

from time to time under this Indenture shall not exceed, with respect to the
Notes, the initial Outstanding Principal Balance for the Notes set forth in the
definition thereof plus the aggregate amount of Additional Interest that has
been added to the principal balance of the Notes in accordance with this
Indenture.

       

      (b)           There

the Noteholders Notes in the principal amounts and maturities and bearing the
interest rates, in each case in registered form and, in the case of the Notes,
substantially in the form set forth in Exhibit A, with such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture, and may have such letters, numbers or
other marks of identification and such legends or endorsements typewritten,
printed, lithographed or engraved thereon, as may, consistently herewith, be
prescribed by the Trustee. The Trustee shall authenticate Notes and make Notes
available for delivery only upon the written order of the Issuer signed by a
Responsible Officer of the Issuer. Such order shall specify the aggregate
principal amount of Notes to be authenticated, the date of issue, whether they
are to be issued as Global Notes or Definitive Notes and delivery
instructions.

       

      Definitive
Notes shall be typewritten, printed, lithographed or engraved or produced by any
combination of these methods, as determined by the Trustee.

       

      Any Notes

Notes in registered form, substantially in the form set forth in the applicable
Exhibit to this Indenture or in any indenture supplemental hereto (each, a
“Permanent Global

Trustee, as custodian for DTC, duly executed by the Issuer and authenticated by
the Trustee as hereinafter provided. The aggregate principal amount of each
Permanent Global Note may from time to time be increased or decreased by
adjustments made on the books and records of the Registrar, as hereinafter
provided.

       

      Any Notes
offered and sold to institutions in offshore transactions in reliance on
Regulation S shall be issued initially in the form of one or more temporary
global Notes in registered form substantially in the form set forth in the
applicable Exhibit to this Indenture or in any indenture supplemental hereto
(each, a “Temporary
Regulation S Global Note”), registered in the name of the nominee of DTC,
deposited with the Trustee, as custodian for DTC, duly executed by the Issuer
and authenticated by the Trustee as hereinafter provided. At any time following
the applicable Regulation S Global Note Exchange Date, upon receipt by the
Trustee and the Issuer of a certificate substantially in the form of Exhibit E, executed
by Euroclear or Clearstream, as the case may be, together with copies of
certificates from Euroclear or Clearstream, as the case may be, certifying that
it has received certification of non-U.S. beneficial ownership of a Temporary
Regulation S Global Note (or portion thereof) with respect to any Notes to be
exchanged, one or more permanent Global Notes for such Notes in registered form
substantially in the form set forth in the applicable Exhibit to this Indenture

Global Note” and, together with each Temporary Regulation S Global Note,
the “Regulation S
Global Notes”) duly executed by the Issuer and authenticated by the
Trustee as hereinafter provided shall be deposited with the Trustee, as
custodian for DTC, and the Registrar shall reflect on its books and records the

Note in an amount equal to the principal amount of such Temporary Regulation S
Global Note exchanged. Until the Regulation S Global Note Exchange Date with
respect to any Temporary Regulation S Global Note, Beneficial Interests in such
Temporary Regulation S Global Note may be held only through Agent Members acting
for and on behalf of Euroclear and Clearstream. A Permanent Regulation S Global
Note shall not bear the Private Placement Legend.

      Notes, if
so provided herein or in any indenture supplemental hereto, shall be issued in
the form of permanent certificated Notes in registered form in substantially the
form set forth in the applicable Exhibit to this Indenture (collectively with
any definitive, fully registered Notes issued pursuant to Section 2.10(b), the
“Definitive

      (c)           Interest
at the Stated Rate of Interest or, after the occurrence and during the
continuance of a Default or an Event of Default at the Default Rate shall accrue
on the Notes from the Closing Date and shall be computed for each Interest
Accrual Period on the basis of a 360-day year consisting of twelve 30-day months
on the Outstanding Principal Balance of such Notes.  If any interest
payment is not made when due on a Payment Date, the unpaid portion of such
interest payment will accrue interest at the rate then applicable to the Notes;
compounded quarterly, until paid in full.

       

      (d)           The
Notes shall be executed on behalf of the Issuer by the manual or facsimile
signature of the Manager.

       

      (e)           Each
Note bearing the manual or facsimile signature of any individual who was at the
time such Note was executed the Manager shall bind the Issuer, notwithstanding
that any such individual has ceased to hold such office prior to the
authentication and delivery of such Notes or any payment thereon.

       

      (f)           At
any time and from time to time after the execution of any Notes, the Issuer may
deliver such Notes to the Trustee for authentication and, subject to the
provisions of Section 2.1(g), the Trustee shall authenticate such Notes by
manual signature upon receipt by it of a written order of the Issuer. The Notes
shall be authenticated on behalf of the Trustee by any Responsible Officer of
the Trustee.

       

      (g)           No
Note shall be entitled to any benefit under this Indenture or be valid or
obligatory for any purpose, unless it shall have been executed on behalf of the
Issuer as provided in Section 2.1(d) and authenticated by or on behalf of the
Trustee as provided in Section 2.1(f). Such signatures shall be conclusive
evidence that such Note has been duly executed and authenticated under this
Indenture. Each Note shall be dated the date of its authentication.

      (h)           Without
the consent of Noteholders of 100% of the Outstanding Principal Balance of the
Notes, the Issuer shall not be permitted to optionally redeem, repurchase,
defease, acquire, retire, refinance or otherwise pay or repay the Notes prior to
the Final Maturity Date.

      Section
2.3                                Registrar and Paying
Agent.

       

      (a)           There
shall at all times be maintained an office or agency in the location set forth
in Section 11.5 where the Notes may be presented or surrendered for registration
of transfer or for exchange (including any additional registrar, each, a “Registrar”) and for
payment thereof (including any additional paying agent, each, a “Paying Agent”) and
where notices and demands to or upon the Issuer in respect of such Notes may be
served. The Trustee shall be the initial Paying Agent and Registrar, and the
Issuer shall not be permitted to act as a Paying Agent or a Registrar. The
Issuer shall cause each Registrar, acting for this purpose on the Issuer’s
behalf, to keep a register of the Notes for which it is acting as Registrar, of
any payment of principal or stated interest on the Notes, and of their transfer
and exchange (the “Register”). Written
notice of the location of each such other office or agency and of any change of
location thereof shall be given by the Trustee to the Issuer and the
Noteholders. In the event that no such office or agency shall be maintained or
no such notice of location or of change of location shall be given,
presentations and demands may be made and notices may be served at the Corporate
Trust Office.

       

      (b)           Each
Authorized Agent in the location set forth in Section 11.5 shall be a bank,
trust company or corporation organized and doing business under the laws of the
U.S., any state or territory thereof or of the District of Columbia, with a
combined capital and surplus of at least U.S. $75,000,000 or having a combined
capital and surplus in excess of U.S. $5,000,000 and the obligations of which,
whether now in existence or hereafter incurred, are fully and unconditionally
Guaranteed by a bank, trust company or corporation organized and doing business
under the laws of the U.S., any state or territory thereof or of the District of
Columbia and having a combined capital and surplus of at least U.S. $75,000,000
and shall be authorized under the laws of the U.S., any state or territory
thereof or the District of Columbia to exercise corporate trust powers, subject
to supervision by Federal or state authorities (such requirements, the “Eligibility
Requirements”). Each Registrar other than the Trustee shall furnish to
the Trustee, at least five Business Days prior to each Payment Date, and at such
other times as the Trustee may request in writing, a copy of the Register
maintained by such Registrar.

      (c)           Any
Person into which any Authorized Agent may be merged or converted or with which
it may be consolidated, or any Person resulting from any merger, consolidation
or conversion to which any Authorized Agent shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of any
Authorized Agent (including the administration of the fiduciary relationship
contemplated by this Indenture), shall be the successor of such Authorized Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 2.3, without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authorized Agent or such successor
Person.

       

      (d)           Any
Authorized Agent may at any time resign by giving written notice of resignation
to the Trustee and the Issuer. The Issuer may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee. Upon
the resignation or termination of an Authorized Agent or if at any time any such
Authorized Agent shall cease to be eligible under this Section 2.3 (when, in
either case, no other Authorized Agent performing the functions of such
Authorized Agent shall have been appointed by the Trustee), the Issuer shall
promptly appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
that has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 2.3. The Issuer shall give written notice of
any such appointment made by it to the Trustee, and in each case the Trustee
shall mail notice of such appointment to all Noteholders as their names and
addresses appear on the Register.

       

      (e)           The
Issuer agrees to pay, or cause to be paid, from time to time to each Authorized
Agent reasonable compensation for its services and to reimburse it for its
reasonable expenses to be agreed to pursuant to separate agreements with each
such Authorized Agent.

       

      Section
2.4                                Paying Agent to Hold Money
in Trust.  The Trustee shall require each Paying Agent other
than the Trustee to agree in writing that all moneys deposited with any Paying
Agent for the purpose of any payment on the Notes shall be deposited and held in
trust for the benefit of the Noteholders entitled to such payment, subject to
the provisions of this Section 2.4. Moneys so deposited and held in trust shall
constitute a separate trust fund for the benefit of the Noteholders with respect
to which such money was deposited.

       

      The
Trustee may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose, direct any Paying Agent to
pay to the Trustee all sums held in trust by such Paying Agent, and, upon such
payment by any Paying Agent to the Trustee, such Paying Agent shall be released
from all further liability with respect to such money.

      Section
2.5                                Method of
Payment.

       

      (a)           On
each Payment Date, the Trustee shall, or shall instruct a Paying Agent to, pay,
to the extent of the Available Collections Amount for such Payment Date and any
funds withdrawn from the Capital Account, the Reserve Account or the Wing
Reserve Account by the Trustee pursuant to Section 3.7(a), to the Noteholders
all interest and principal on each Note in the amounts determined by the
Calculation Agent pursuant to Section 3.5; provided, that
payment on a Temporary Regulation S Global Note shall be made to the Noteholder
thereof only in conformity with Section 2.5(c). Each payment on any Payment Date
other than the final payment with respect to the Notes shall be made by the
Trustee or Paying Agent to the Noteholders as of the Record Date for such
Payment Date. The final payment with respect to the Notes, however, shall be
made only upon presentation and surrender of such Note by the Noteholder or its
agent at the Corporate Trust Office or agency of the Trustee or Paying
Agent.

       

      (b)           At
such time, if any, as the Notes are issued in the form of Definitive Notes,
payments on a Payment Date shall be made by check mailed to each Noteholder of a
Definitive Note on the applicable Record Date at its address appearing on the
Register maintained with respect to the Notes. Alternatively, upon application
in writing to the Trustee, not later than the applicable Record Date, by a
Noteholder, any such payments shall be made by wire transfer to an account
designated by such Noteholder at a financial institution in New York, New York;
provided, that
the final payment for the Notes shall be made only upon presentation and
surrender of the Definitive Notes by the Noteholder or its agent at the
Corporate Trust Office or agency of the Trustee or Paying Agent. Payments in
respect of the Notes represented by a Global Note (including principal and
interest) shall be made by wire transfer of immediately available funds to the
account specified by DTC.

       

      (c)           The
beneficial owner of a Temporary Regulation S Global Note may arrange to receive
payments through Euroclear or Clearstream on such Temporary Regulation S Global
Note only after delivery by such beneficial owner to Euroclear or Clearstream,
as the case may be, of a written certification substantially in the form of
Exhibit F and
upon delivery by Euroclear or Clearstream, as the case may be, to the Paying
Agent of a certification or certifications substantially in the form of Exhibit G. No
interest shall be paid to any beneficial owner and no interest shall be paid to
Euroclear or Clearstream on such beneficial owner’s interest in a Temporary
Regulation S Global Note unless Euroclear or Clearstream, as the case may be,
has provided such a certification to the Paying Agent with respect to such
interest.

       

      (d)           If
the Interest Amount due on the Notes is not paid in full on any Payment Date,
notwithstanding anything to the contrary in this Indenture, the Trustee, at the
written direction of the Issuer and upon no less than 10 days prior written
notice to the Noteholders, shall pay such Interest Amount (or portion thereof),
together with Additional Interest on any portion of the Interest Amount not paid
on the immediately preceding Payment Date, to the Noteholders out of available
funds in the Collection Account at any time after such immediately preceding
Payment Date but prior to the immediately succeeding Payment Date; provided, that all
Trustee Expenses, the Visual Connections Payments, if any, the Greiner Payments,
if any, Other Expenses (subject to the limitation set forth in Section
3.7(a)(iii)) and the Servicing Fee, in each case,  with respect to
such preceding Payment Date contemplated by Section 3.7(a)(i), Section
3.7(a)(ii), Section 3.7(a)(iii) and Section 3.7(a)(iv), respectively, shall have
been paid. Any such payment shall be made to the Noteholders as of the Record
Date for the immediately preceding Payment Date.

      Section
2.6                                Minimum
Denominations.  The Notes shall be issued in minimum
denominations of U.S. $250,000 and integral multiples of U.S. $1,000 in excess
thereof.

       

      Section
2.7                                Transfer and Exchange;
Cancellation.  The Notes are issuable only in registered form.
A Noteholder or a Beneficial Holder may transfer a Note or a Beneficial Interest
therein only by written application to the Registrar stating the name of the
proposed transferee and otherwise complying with the terms of this Indenture,
including the requirement for the execution and delivery of a Confidentiality
Agreement by such proposed transferee to the Registrar relating to such transfer
as set forth in Section 2.11(j). No such transfer shall be effected until, and
such proposed transferee shall succeed to the rights of a Noteholder or a
Beneficial Holder only upon, final acceptance and registration of the transfer
by the Registrar and confirmation by the Registrar pursuant to Section 2.11(j)
that such Noteholder or such Beneficial Holder has executed and delivered an
appropriate Confidentiality Agreement to the Registrar.

       

      Prior to
the due presentment for registration of transfer of a Note and satisfaction of
the requirements specified in the last sentence of the preceding paragraph, the
Issuer and the Trustee may deem and treat the applicable registered Noteholder
as the absolute owner and holder of such Note for the purpose of receiving
payment of all amounts payable with respect to such Note and for all other
purposes and shall not be affected by any notice to the contrary. The Registrar
(if different from the Trustee) shall promptly notify the Trustee in writing and
the Trustee shall promptly notify the Issuer of each request for a registration
of transfer of a Note by furnishing the Issuer a copy of such
request.

       

      Furthermore,
any Noteholder of a Global Note shall, by acceptance of such Global Note, agree
that, subject to Section 2.10(b) and Section 2.11, transfers of Beneficial
Interests in such Global Note may be effected only through a book-entry system
maintained by the Noteholder of such Global Note (or its agent) and that
ownership of a Beneficial Interest in such Global Note shall be required to be
reflected in a book-entry system. When Notes are presented to the Registrar with
a request to register the transfer or to exchange them for an equal principal
amount of Notes of other authorized denominations, the Registrar shall register
the transfer or make the exchange as requested if its requirements for such
transactions are met (including, in the case of a transfer, that such Notes are
duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Trustee and Registrar duly executed by the Noteholder
thereof or by an attorney who is authorized in writing to act on behalf of the
Noteholder). To permit registrations of transfers and exchanges, the Issuer
shall execute and the Trustee shall authenticate Notes at the Registrar’s
request. Except as set forth in Section 2.8 and Section 2.9, no service charge
shall be made for any registration of transfer or exchange or redemption of the
Notes.

       

      The
Registrar shall not be required to exchange or register the transfer of any
Notes as above provided during the 15-day period preceding the Final Maturity
Date of any such Notes.

       

      
        
          
          

        

        
          30

          
            

          

        

        
          
          

        

      

       

      The
Issuer at any time may deliver Notes to the Trustee for cancellation. The
Trustee and no one else shall cancel and destroy in accordance with its
customary practices in effect from time to time (subject to the record retention
requirements of the Exchange Act) any such Notes, together with any other Notes
surrendered to it for registration of transfer, exchange or payment. The Issuer
may not issue new Notes to replace Notes it has redeemed, paid or delivered to
the Trustee for cancellation.

       

      Section
2.8                                Mutilated, Destroyed, Lost
or Stolen Notes.  If any Note shall become mutilated,
destroyed, lost or stolen, the Issuer shall, upon the written request of the
Noteholder thereof and presentation of the Note or satisfactory evidence of
destruction, loss or theft thereof to the Trustee or Registrar and a
confirmation by the Registrar to the Trustee that such Noteholder (or Beneficial
Holder of the Beneficial Interest therein) has executed and delivered to the
Registrar a Confidentiality Agreement, issue, and the Trustee shall authenticate
and the Trustee or Registrar shall deliver in exchange therefor or in
replacement thereof, a new Note, payable to such Noteholder in the same
principal amount, of the same maturity, with the same payment schedule, bearing
the same interest rate and dated the date of its authentication. If the Note
being replaced has become mutilated, such Note shall be surrendered to the
Trustee or the Registrar and forwarded to the Issuer by the Trustee or such
Registrar. If the Note being replaced has been destroyed, lost or stolen, the
Noteholder thereof shall furnish to the Issuer, the Trustee and the Registrar
(a) such security or indemnity as may be required by the Issuer, the Trustee and
the Registrar to save each of them harmless (an unsecured indemnity from any QIB
being satisfactory security or indemnity) and (b) evidence satisfactory to the
Issuer, the Trustee and the Registrar of the destruction, loss or theft of such
Note and of the ownership thereof (an affidavit from any QIB being satisfactory
evidence). The Noteholders will be required to pay any tax or other governmental
charge imposed in connection with such exchange or replacement and any other
expenses (including the fees and expenses of the Trustee and the Registrar)
connected therewith.

       

      Section
2.9                                Payments of Transfer
Taxes.  Upon the transfer of any Note or Notes pursuant to
Section 2.7, the Issuer or the Trustee may require from the party requesting
such new Note or Notes payment of a sum to reimburse the Issuer or the Trustee
for, or to provide funds for the payment of, any transfer tax or similar
governmental charge payable in connection therewith.

       

      Section
2.10                                Book-Entry
Provisions.

       

      (a)           Global
Notes shall (i) be registered in the name of DTC or a nominee of DTC, (ii) be
delivered to the Trustee as custodian for DTC and (iii) except as set forth
therein or in this Indenture, bear the Private Placement Legend.

       

      Members
of, or participants in, DTC (“Agent Members”) shall
have no rights under this Indenture with respect to any Global Note held on
their behalf by DTC, or the Trustee as its custodian, or under such Global Note,
and DTC may be treated by the Issuer, the Trustee and any agent of the Issuer or
the Trustee as the absolute owner of such Global Note for all purposes
whatsoever.

       

      
        
          
          

        

        
          31

          
            

          

        

        
          
          

        

      

       

      Whenever
notice or other communication to the Noteholders of Global Notes is required
under this Indenture, unless and until Definitive Notes shall have been issued
pursuant to Section 2.10(b), the Trustee shall give all such notices and
communications specified herein to be given to Noteholders to DTC and/or the
Agent Members, and shall make available additional copies as requested by such
Agent Members, subject to the limitations on distribution contained in Section
2.13.

       

      Notwithstanding
the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent
of the Issuer or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by DTC or impair, as between DTC and its
Agent Members, the operation of customary practices governing the exercise of
the rights of a Noteholder under any Global Note. Neither the Issuer nor the
Trustee shall be liable for any delay by DTC in identifying the Agent Members in
respect of the Global Notes, and the Issuer and the Trustee may conclusively
rely on, and shall be fully protected in relying on, instructions from DTC for
all purposes (including with respect to the registration and delivery, and the
respective principal amounts, of any Global Notes to be issued).

       

      (b)           Transfers
of a Global Note shall be limited to transfers of such Global Note in whole, but
not in part, to DTC, its successors or their respective nominees. Interests of
Agent Members in a Global Note may be transferred in accordance with the rules
and procedures of DTC and the provisions of Section 2.11. Except as set forth in
Section 2.11(a), Definitive Notes shall be issued to the individual Agent
Members or Beneficial Holders or their nominees in exchange for their Beneficial
Interests in a Global Note only if (i) the Issuer advises the Trustee in writing
that DTC is no longer willing or able to properly discharge its responsibilities
as depositary with respect to such Notes and the Trustee or the Issuer is unable
to appoint a qualified successor within 90 days of such notice, (ii) the Issuer,
at its option, elects to terminate the book-entry system through DTC or (iii)
during the occurrence of an Event of Default, Noteholders of a majority of the
Outstanding Principal Balance of Notes advise the Issuer, the Trustee and DTC
through the Agent Members in writing that the continuation of a book-entry
system through DTC (or a successor thereto) is no longer in the best interests
of the Noteholders. Upon the occurrence of any event described in the
immediately preceding sentence, the Trustee shall notify all affected
Noteholders, through DTC, of the occurrence of such event and of the
availability of Definitive Notes; provided, however, that in no
event shall the Temporary Regulation S Global Note be exchanged for Definitive
Notes prior to the later of (x) the Regulation S Global Note Exchange Date and
(y) the date of receipt by the Issuer of any certificates determined by it to be
required pursuant to Rule 903 or 904 under the Securities Act. Upon surrender to
the Trustee of the Global Notes held by DTC, accompanied by registration
instructions from DTC for registration of Definitive Notes, the Issuer shall
issue and the Trustee shall authenticate and deliver the Definitive Notes to the
Agent Members and Beneficial Holders or their nominees in accordance with the
instructions of DTC.

       

      None of
the Issuer, the Registrar, the Paying Agent or the Trustee shall be liable for
any delay in delivery of such instructions and may conclusively rely on, and
shall be fully protected in relying on, such registration instructions. Upon the
issuance of Definitive Notes, the Trustee shall recognize the Persons in whose
name the Definitive Notes are registered in the Register as Noteholders
hereunder. Neither the Issuer nor the Trustee shall be liable if the Trustee or
the Issuer is unable to locate a qualified successor to DTC.

       

      
        
          
          

        

        
          32

          
            

          

        

        
          
          

        

      

       

      Definitive
Notes will be freely transferable and exchangeable at the office of the Trustee
or the office of the Registrar upon compliance with the requirements set forth
herein. In the case of a transfer of only part of a holding of Definitive Notes,
a new Definitive Note shall be issued to the transferee in respect of the part
transferred and a new Definitive Note in respect of the balance of the holding
not transferred shall be issued to the transferor and may be obtained at the
office of the applicable Registrar.

       

      (c)           Any
Beneficial Interest in one of the Global Notes that is transferred to a Person
who takes delivery in the form of an interest in another Global Note will, upon
transfer, cease to be an interest in such Global Note and become an interest in
such other Global Note and, accordingly, will thereafter be subject to all
transfer restrictions, if any, and other procedures applicable to Beneficial
Interests in such other Global Note for as long as it remains such an
interest.

       

      (d)           Any
Definitive Note delivered in exchange for an interest in a Permanent Global Note
pursuant to Section 2.10(b) shall, except as otherwise provided by Section
2.11(f), bear the Private Placement Legend applicable to a Permanent Global
Note.

       

      (e)           Upon
the request of Servicer or a Noteholder(s) owning more than 10% of the
Outstanding Principal Balance of the Notes from time to time, the Trustee shall
request DTC to provide a list of the Agent Members holding Beneficial Interests
in the Notes on a particular Record Date and shall provide such list to Servicer
or such Noteholder(s), as the case may be. Any cost involved in obtaining such
list shall be included in Trustee Expenses to be reimbursed in accordance with
Section 3.7(a).  Not later than five Business Days prior to each
Payment Date or any other date on which a Distribution Report is to be
distributed pursuant to Section 2.13(a) to Agent Members and Beneficial Holders,
Servicer shall provide a list to the Trustee of the Agent Members, Beneficial
Holders and Noteholders (other than DTC or its nominee or any other depositary)
that have provided Confidentiality Agreements to the Issuer, Trustee or
Registrar, and the Trustee shall distribute such reports only to the Agent
Members, Beneficial Holders and Noteholders named on such list.

2.11                                Special Transfer

Permanent Global Note, upon receipt by the Registrar of (A) the documents
required by Section 2.11(a)(i), including the Confidentiality Agreement, and (B)
instructions given in accordance with DTC’s and the Registrar’s procedures, the
Registrar shall reflect on its books and records the date and a decrease in the
principal amount of the Permanent Global Note in an amount equal to the
principal amount of the Beneficial Interest in the Permanent Global Note to be
transferred, and the Issuer shall execute, and the Trustee shall authenticate
and deliver, one or more Definitive Notes of like tenor and amount.

       

      (b)           The
following provisions shall apply with respect to any proposed transfer of a
Beneficial Interest in a Permanent Global Note or a Definitive Note to a QIB
(excluding Non-U.S. Persons):

each case, each transferee has delivered to the Registrar a Confidentiality
Agreement duly executed by such transferee.

       

      (ii)           If
the proposed transferee is an Agent Member, and the Note to be transferred is a
Definitive Note, upon receipt by the Registrar of the documents referred to in
Section 2.11(b)(i), including the Confidentiality Agreement, and instructions

amount at maturity of the Permanent Global Note in an amount equal to the
principal amount at maturity of the Definitive Note to be transferred, and the
Trustee shall cancel the Definitive Note so transferred (upon written direction
from the Registrar if different from the Trustee).

       

      (c)           With

          34

          
            

          

        

        
          
          

        

      

       

      (d)           With
respect to any proposed transfer of any Beneficial Interest in a Permanent
Regulation S Global Note, the Registrar shall reflect the transfer of such
Beneficial Interest on its books and records if the proposed transferee has duly
executed and delivered to the Registrar a Confidentiality Agreement (in which
case the transferee will receive a corresponding Beneficial Interest in the
Permanent Regulation S Global Note, unless otherwise agreed by the Issuer and

      (ii)           The
Registrar shall register or reflect on its books and records, as the case may
be, any proposed transfer of a Note (or a Beneficial Interest therein) to any
Non-U.S. Person if the Note to be transferred is a Definitive Note or a
Beneficial Interest in a Permanent Global Note, upon receipt of a certificate
substantially in the form of Exhibit H from the
proposed transferor and a Confidentiality Agreement duly executed and delivered
to the Registrar by such Non-U.S. Person.

       

      
        
          
          

        

        
          35

          
            

          

        

        
          
          

        

      

       

      (iii)           (A)
If the proposed transferor is an Agent Member holding a Beneficial Interest in a
Permanent Global Note, upon receipt by the Registrar of (x) the documents, if
any, required by Section 2.11(e)(ii) and (y) instructions in accordance with
DTC’s and the Registrar’s procedures, the Registrar shall reflect on its books
and records the date and a decrease in the principal amount of the Permanent
Global Note in an amount equal to the principal amount of the Beneficial
Interest in such Permanent Global Note to be transferred, and (B) if the

instructions given in accordance with DTC’s and the Registrar’s procedures, the
Registrar shall reflect on its books and records the date and an increase in the

the principal amount of the Beneficial Interest in such Permanent Global Note or
any Definitive Notes issued in exchange for such Beneficial Interest in such
Permanent Global Note to be transferred, and the Trustee shall cancel the
Definitive Note, if any, so transferred or decrease the amount of the Permanent
Global Note (upon written direction from the Registrar if different from the
Trustee).

       

      (f)           Upon
the transfer, exchange or replacement of Notes bearing the Private Placement
Legend, the Registrar shall deliver only Notes that bear the Private Placement
Legend unless there is delivered to the Registrar an Opinion of Counsel
reasonably satisfactory to the Issuer and the Trustee to the effect that neither
such Private Placement Legend nor the related restrictions on transfer are
required in order to maintain compliance with the provisions of the Securities
Act.

       

      (g)           By
its acceptance of any Note bearing the Private Placement Legend, each Noteholder
of such Note acknowledges the restrictions on transfer of such Note set forth in
this Indenture and in the Private Placement Legend and agrees that it will
transfer such Note (or the Beneficial Interest therein) only as provided in this
Indenture and in accordance with the Private Placement Legend. The Registrar
shall not register or reflect on its books and records a transfer of any Note
(or any Beneficial Interest therein) unless such transfer complies with the
restrictions on transfer of such Note set forth in this Indenture. In connection
with any transfer of Notes (or Beneficial Interests therein), each Noteholder
agrees by its acceptance of the Notes to furnish the Trustee the certifications
and legal opinions described herein to confirm that such transfer is being made
pursuant to an exemption from, or a transaction not subject to, the registration
requirements of the Securities Act; provided, that the
Trustee shall not be required to determine (but may rely on a determination made
by the Issuer with respect to) the sufficiency of any such legal
opinions.

       

      (h)           The
Notes shall be issued pursuant to an exemption from registration under the
Securities Act. The Issuer agrees that it will not at any time (i) apply to
list, list or list upon notice of issuance, (ii) consent to or authorize an
application for the listing or the listing of, or (iii) enable or authorize the
trading of the Notes on an established securities market, including (w) a
national securities exchange registered under the Exchange Act or exempted from
registration because of the limited volume of transactions, (x) a foreign
securities exchange that, under the law of the jurisdiction where it is
organized, satisfies regulatory requirements that are analogous to the
regulatory requirements under the Exchange Act applicable to exchanges described
in Section 2.11(h)(iii)(w), (y) a regional or local exchange or (z) an
over-the-counter market, as the term “established securities market” and the
terms in this Section 2.11(h) are defined for purposes of Section 7704 of the
Code.

      (i)           The
Trustee shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.10 or this Section 2.11. The
Issuer shall have the right to inspect and make copies of all such letters,
notices, Confidentiality Agreements or other written communications at any
reasonable time upon the giving of reasonable written notice to the
Trustee.

       

      (j)           Each
Noteholder, Agent Member and Beneficial Holder agrees that it will not take any
action to transfer any Note (or any Beneficial Interest therein) to a proposed
transferee without causing such proposed transferee to execute and deliver to
the Registrar an appropriate Confidentiality Agreement relating to such transfer
as set forth in this Section 2.11. After the Closing Date with respect to the
Notes, forms of Confidentiality Agreements will be available to Noteholders,
Agent Members and Beneficial Holders and proposed transferees of the Notes (or
the Beneficial Interests therein) from the Registrar, initially at the Corporate
Trust Office. Each such Confidentiality Agreement shall be delivered to the
Registrar promptly upon execution by the parties thereto. The Registrar shall
promptly, but in any event no later than two Business Days of receipt of any
such executed Confidentiality Agreement, furnish a copy of such executed
Confidentiality Agreement to the Trustee, the Issuer and Servicer and shall send
additional copies of any such Confidentiality Agreements to the Issuer and
Servicer from time to time on request from such Person.

       

      Section
2.12                                Temporary Definitive
Notes.  Pending the preparation of Definitive Notes, the Issuer
may execute and the Trustee may authenticate and deliver temporary Definitive
Notes that are printed, lithographed, typewritten or otherwise produced, in any
denomination, containing substantially the same terms and provisions as are set
forth in the applicable Exhibit or in any indenture supplemental hereto, except
for such appropriate insertions, omissions, substitutions and other variations
relating to their temporary nature as the Manager executing such temporary
Definitive Notes may determine, as evidenced by his or her execution of such
temporary Definitive Notes.

       

      If
temporary Definitive Notes are issued, the Issuer shall cause such Definitive
Notes to be prepared without unreasonable delay. After the preparation of
Definitive Notes, the temporary Definitive Notes shall be exchangeable for
Definitive Notes upon surrender of such temporary Definitive Notes at the
Corporate Trust Office, without charge to the Noteholder
thereof.  Upon surrender for cancellation of any one or more temporary
Definitive Notes, the Issuer shall execute and the Trustee shall authenticate
and deliver in exchange therefor Definitive Notes, in authorized denominations
and in the same aggregate principal amounts. Until so exchanged, such temporary
Definitive Notes shall in all respects be entitled to the same benefits under
this Indenture as Definitive Notes.

       

      Section
2.13                                Statements to
Noteholders.

       

      (a)           On
each Payment Date and any other date for distribution of any payments with
respect to the Notes then Outstanding, the Trustee shall deliver a report,
substantially in the form attached as Exhibit D and
prepared by Servicer, giving effect to such payments (each, a “Distribution
Report”), to (i) each Noteholder included on the Approved Holder List,
(ii) the Issuer, (iii) the Calculation Agent and (iv) MedPro, and to no other
Person. Each Noteholder shall be entitled to receive the Distribution Report
only if such Noteholder has executed and delivered to the Registrar a
Confidentiality Agreement.

      (b)           Each
Distribution Report provided to each Noteholder by the Trustee for each Payment
Date pursuant to Section 2.13(a), commencing October 30, 2010, shall be
accompanied by (i) a statement prepared by Servicer setting forth an analysis of
the Collection Account activity for the period commencing on the day next
following the preceding Calculation Date and ending on the Calculation Date
relating to such Payment Date, (ii) such information, if any, that MedPro shall
have provided to the Trustee pursuant to Section 6.3 of the Purchase and Sale
Agreement during the Interest Accrual Period then ended and (iii) the
information, if any, that the Issuer shall have provided to the Trustee pursuant
to Section 5.3 (or Servicer shall have provided to the Trustee pursuant to
Section 4.1 of the Servicing Agreement) during the Interest Accrual Period then
ended.

       

      (c)           After
the end of each calendar year but not later than the latest date permitted by
law, the Trustee shall (or shall instruct any Paying Agent to) furnish to each
Person who at any time during such calendar year was a Noteholder of Notes a
statement (for example, a Form 1099 or any other means required by law) prepared
by the Trustee containing the sum of the amounts determined pursuant to Exhibit D with
respect to the Notes for such calendar year or, in the event such Person was a
Noteholder during only a portion of such calendar year, for the applicable
portion of such calendar year, and such other items as are readily available to
the Trustee and which a Noteholder shall reasonably request as necessary for the
purpose of such Noteholder’s preparation of its U.S. federal income or other tax
returns. So long as any of the Notes are registered in the name of DTC or its
nominee, such report and such other items will be prepared on the basis of such
information supplied to the Trustee by DTC and the Agent Members and will be
delivered by the Trustee to DTC and by DTC to the applicable Beneficial Holders
in the manner described above. In the event that any such information has been
provided by any Paying Agent directly to such Person through other tax-related
reports or otherwise, the Trustee in its capacity as Paying Agent shall not be
obligated to comply with such request for information.

       

      (d)           At
such time, if any, as the Notes are issued in the form of Definitive Notes, the
Trustee shall prepare and deliver the information described in Section 2.13(c)
to each Noteholder of a Definitive Note for the relevant period of beneficial
ownership of such Definitive Note as appears on the books and records of the
Trustee, subject to confirmation that each such Noteholder has executed and
delivered to the Registrar a Confidentiality Agreement.

       

      (e)           The
Trustee shall be at liberty to sanction any method of giving notice to the
Noteholders if in its opinion, such method is reasonable, having regard to the
number and identity of the Noteholders and/or to market practice then
prevailing, is in the best interests of the Noteholders, and any such notice
shall be deemed to have been given on such date as the Trustee may approve;
provided, that
notice of such method is given to the Noteholders in such manner as the Trustee
shall require.

      Section
2.14                                CUSIP, CINS, ISIN and
Private Placement Numbers.  The Issuer in issuing the Notes may
use CUSIP, CINS, ISIN, private placement or other identification numbers (if
then generally in use), and, if so, the Trustee shall use such CUSIP, CINS,
ISIN, private placement or other identification numbers, as the case may be, in
notices of redemption or exchange as a convenience to Noteholders; provided, that any
such notice shall state that no representation is made as to the correctness of
such numbers either as printed on the Notes or as contained in any notice of
redemption or exchange and that reliance may be placed only on the other
identification numbers printed on the Notes; provided, further, that failure
to use CUSIP, CINS, ISIN, private placement or other identification numbers in
any notice of redemption or exchange shall not affect the validity or
sufficiency of such notice.

       

      Section
2.15                                Additional
Issuances.  During the thirty day period following the Closing
Date, the Issuer may issue and sell additional Notes and the Issuer may use the
proceeds to make a distribution to MedPro, provided, that the following
conditions are satisfied:

       

      (i)           the
original principal amount of such additional Notes shall not exceed $5,000,000
in the aggregate;

       

      (ii)           such
additional Notes must be issued for a cash sales price and a portion of the
proceeds thereof, as determined at the time of such issuance, must be deposited
in the Reserve Account at the time of such issuance;

       

      (iii)           the
terms (other than the date of issuance , the issue price and the date from which
interest will accrue) of such Notes must be identical to the terms of the Notes
issued on the Closing Date;

       

      (iv)           the
Noteholders shall have been notified in writing 10 days prior to such issuance
and shall have been afforded the first opportunity to purchase such additional
Notes in an amount not to exceed the percentage of the outstanding Notes each
Noteholder held immediately prior to such issuance of such additional Notes and
on the same terms offered to investors generally;

       

      (v)           there
shall not have occurred and be continuing a Default or an Event of Default;
and

       

      (vi)           an
opinion of counsel to the Issuer and a certificate of a Responsible Officer of
the Issuer shall have been delivered to the Trustee, each to be in accordance
with the requirements of this Indenture.

      Section
3.1                                Establishment of
Accounts.

       

      (a)           Pursuant
to the terms of the Servicing Agreement, the Issuer will cause Servicer, acting
on behalf of the Issuer, to establish and maintain with the Operating Bank on
its books and records in the name of the Issuer, subject to the lien in favor of
the Trustee established by this Indenture, (i) a collection account (the “Collection Account”),
(ii) a reserve account (the “Reserve Account”),
(iii) another reserve account (the “Wing Reserve Account”), (iv) a
holding account (the “Holding Account”),
(v) a capital contribution account (the “Capital Account”) and
(vi) any additional accounts the establishment of which is set forth in a
Manager Resolution delivered to the Trustee, in each case, at such time as is
set forth in this Section 3.1 or in such Manager Resolution. Each Account shall
be established and maintained as an Eligible Account so as to create, perfect
and establish the priority of the security interest of the Trustee in such
Account and all cash, Eligible Investments and other property from time to time
deposited therein and otherwise to effectuate the lien of the Indenture
Estate.

      (b)           The
Trustee shall have sole dominion and control over the Accounts (including, among
other things, the sole power to direct withdrawals or transfers from the
Accounts and to direct the investment and reinvestment of funds in the Accounts,
subject to Section 3.2). The Trustee shall make withdrawals and transfers from
the Accounts in accordance with the terms of this Indenture based on the
Relevant Information and as calculated by it pursuant to this Indenture. The
Issuer, Servicer and the Trustee acknowledge that the Accounts are “deposit
accounts” or “investment property” within the meaning of Section 9-102 of the
UCC and that the Trustee has “control,” for purposes of Section 9-314 of the
UCC, of Accounts that are maintained with the Trustee as the Operating
Bank.  The Operating Bank agrees that the State of New York shall be
deemed to be the “bank’s jurisdiction” within the meaning of Section 9-304 of
the UCC.  The Issuer and Servicer agree that, if any Account is
established or maintained with any Operating Bank other than the Trustee, the
Issuer and Servicer shall cause such Operating Bank to enter into an agreement
with the Trustee, the Issuer and Servicer pursuant to which such Operating Bank
agrees to comply with instructions originated by the Trustee directing the
disposition, investment and reinvestment of funds in all Accounts maintained
with such Operating Bank without the further consent of the Issuer or Servicer
and shall take such other actions as are reasonably required by the Trustee to
establish its “control”, for purposes of Section 9-314 of the UCC, over any such
Accounts.

       

      (c)           If,
at any time, any Account ceases to be an Eligible Account, the Issuer will cause
Servicer or an agent thereof, within ten Business Days, to establish a new
Account meeting the conditions set forth in this Section 3.1 in respect of such
Account and transfer any cash or investments in the existing Account to such new
Account, and, from the date such new Account is established, it shall have the
same designation as the existing Account. If the Operating Bank should change at
any time, then Servicer, acting on behalf of the Issuer, shall thereupon
promptly establish replacement Accounts as necessary at the successor Operating
Bank and transfer the balance of funds in each Account then maintained at the
former Operating Bank pursuant to the terms of the Servicing Agreement to such
successor Operating Bank.

       

      (d)           The
Issuer shall cause Servicer to establish and maintain the Collection Account at
the Operating Bank not later than the Closing Date, and the Collection Account
shall bear a designation clearly indicating that the funds deposited therein are
held for the benefit of the Trustee. Except as expressly provided herein, all
Collections shall be deposited in the Collection Account and transferred
therefrom in accordance with the terms of this Indenture. No funds shall be
deposited in the Collection Account that do not constitute Collections except as
expressly provided in this Indenture without the prior written consent of the
Trustee.

      (e)           The
Issuer shall cause Servicer to establish and maintain the Reserve Account at the
Operating Bank not later than the Closing Date, and the Reserve Account shall
bear a designation clearly indicating that the funds deposited therein are held
for the benefit of the Trustee. Any such amounts held in the Reserve Account may
be transferred pursuant to Section 3.7.  As of the Closing Date,
$4,500,000 shall be placed in the Reserve Account.

       

      (f)           The
Issuer shall cause Servicer to establish and maintain the Wing Reserve Account
at the Operating Bank not later than the Closing Date, and the Wing Reserve
Account shall bear a designation clearly indicating that the funds deposited
therein are held for the benefit of the Trustee. Any such amounts held in the
Wing Reserve Account may be transferred pursuant to Section 3.7 or transferred
to MedPro pursuant to Section 3.4(c).  As of the Closing Date,
$7,870,000 shall be placed in the Wing Reserve Account.

       

      (g)           The
Issuer shall cause Servicer to establish and maintain the Holding Account at the
Operating Bank not later than the Closing Date, and the Holding Account shall
bear a designation clearly indicating that the funds deposited therein are held
for the benefit of the Trustee. Any such amounts held in the Holding Account may
be transferred pursuant to Section 3.6.

       

      (h)           The
Issuer shall cause Servicer to establish and maintain the Capital Account at the
Operating Bank not later than the Closing Date in the name of the Trustee for
the benefit of the Trustee and shall deposit all such capital contributions in
the Capital Account. The Issuer also may direct the Trustee to deposit in the
Capital Account all or a portion of any amount otherwise distributable to the
Issuer pursuant to Section 3.7(a)(xi).  The Trustee shall maintain a
record of the portion of funds on deposit in the Capital Account allocable to
capital contributions and the portion allocable to such deposits.  All
such capital contributions shall be held in such Account and transferred to the
Collection Account only to the extent permitted by Section 3.7.

       

      (i)           If
any Account shall be a securities account (such account, the “Securities  Account”),
then the Operating Bank, in its capacity as securities intermediary (the “Securities
Intermediary”), hereby agrees and confirms that (i) the Securities
Intermediary is a bank or broker that in the ordinary course of its business
maintains securities accounts for others and is acting in that capacity in
maintaining the Securities Account, (ii) the Issuer will be entitled to exercise
the rights that comprise each Financial Asset credited to the Securities Account
and (iii) its books and records will contain appropriate entries to reflect
the status of the Issuer as the Person having a security entitlement against the
securities intermediary with respect to each Financial Asset credited to the
Securities Account by the Securities Intermediary.

       

      (j)           The
Securities Intermediary acknowledges that (i) the Issuer has granted a security
interest in all of the Issuer’s right, title and interest in and to any
Financial Assets from time to time credited to the Securities Account and (ii)
prior to the satisfaction of the Secured Obligations, it will comply with any
entitlement orders originated by the Trustee (including entitlement orders
directing the Securities Intermediary to transfer or redeem any Financial
Assets) with respect to the Securities Account without further consent from the
Issuer.

      (k)           The
Securities Intermediary hereby agrees that any property credited to the
Securities Account (whether “investment property”, “financial asset” or
“security” (each as defined in the UCC) or cash, and the proceeds thereof) shall
be treated as “financial assets” within the meaning of Section 8-102(a)(9) of
the UCC.

       

      Section
3.2                                Investments of
Cash.  For so long as any Notes remain Outstanding or any other
Secured Obligations are Outstanding, the Trustee, at the written direction of
Servicer or the Issuer, shall, invest and reinvest the funds on deposit in the
Accounts in Eligible Investments; provided, however, that, so
long as an Event of Default has occurred and is continuing, the Trustee shall
invest such amount in Eligible Investments described in clause (d) of the
definition thereof from the time of receipt thereof until such time as such
amounts are required to be distributed pursuant to the terms of this Indenture.
In the absence of written direction delivered to the Trustee from the Issuer or
the Servicer, the Trustee shall invest any funds in Eligible Investments
described in clause (d) of the definition thereof.  The Trustee shall
make such investments and reinvestments in accordance with the terms of the
following provisions:

       

      (a)           the
Eligible Investments shall have maturities and other terms such that sufficient
funds shall be available to make required payments pursuant to this Indenture on
the Business Day immediately preceding the first Payment Date after which such
investment is made;

       

      (b)           if
any funds to be invested are not received in the Accounts by 1:00 p.m., New York
City time, on any Business Day, such funds shall, if possible, be invested in
overnight Eligible Investments; and

       

      (c)           all
interest and earnings on Eligible Investments held in the Accounts shall be
invested in Eligible Investments on an overnight basis and credited to the
appropriate Account until the next Payment Date.

       

      The
Issuer acknowledges that regulations of the U.S. Comptroller of the Currency
grant the Issuer the right to receive confirmations of security transactions as
they occur. The Issuer specifically waives receipt of such confirmations to the
extent permitted by law and acknowledges that the Trustee will instead furnish
periodic cash transaction statements that will detail all investment
transactions as set forth in this Indenture.

       

      Section
3.3                                Closing Date Deposits;
Withdrawals and Transfers.

       

      (a)           On
the Closing Date, the Trustee shall, subject to the receipt of written direction
from the Issuer upon receipt of the proceeds of the sale by the Issuer of the
Notes, make the following payments and transfers to the Accounts from such
proceeds:

       

      (i)           pay
to such Persons such amounts as shall be specified by the Issuer such
Transaction Expenses due and payable in connection with the issuance and sale of
the Notes;

      (ii)           deposit
to the Reserve Account and the Wing Reserve Account the amounts set forth in
Sections 3.1(e) and (f), respectively; and

       

      (iii)           remit
to MedPro an amount specified by the Issuer as the Cash Purchase
Price.

       

      (b)           The
Trustee shall hold all funds received on or prior to the Closing Date from the
Note Purchasers in trust for the Note Purchasers pending completion of the
closing of the transactions contemplated by this Indenture. Upon receipt by the
Trustee of the aggregate Purchase Price, the Issuer shall direct the Trustee to
disburse the Purchase Price in accordance with this Section 3.3. If the
aggregate Purchase Price shall not have been received by the Trustee by 3:30
p.m. (New York City time) on the Closing Date, or if the closing of the
transactions contemplated by this Indenture shall not otherwise be capable of
being consummated by 3:30 p.m. (New York City time) on the Closing Date, then
each Note Purchaser who has paid its respective portion of the Purchase Price
shall have the right to instruct the Trustee at or after 3:30 p.m. (New York
City time) on the Closing Date to return such portion of the Purchase Price to
such Note Purchaser as soon thereafter as reasonably practicable.

January 30, 2013, or earlier as set forth in Section 3.7(a), the Trustee shall
transfer to the Collection Account the balance, if any, remaining in the Reserve
Account after the payment of the Interest Amount on the Notes for such Payment

Collections Amount for such Payment Date.

       

      (c)           Upon
written notice from Servicer acknowledged and agreed by Greiner in writing to
the Trustee stating that MedPro’s obligation to pay Liquidated Damages to
Greiner has been satisfied or that MedPro has obtained regulatory approvals
necessary to the marketing of the Wing Product (as defined in the Purchase and
Sale Agreement) on or prior to [*], the Trustee shall transfer to an account
designated in writing by MedPro the balance, if any, remaining in the Wing
Reserve Account after the payment of the amounts required to be paid on such
Payment Date pursuant to Section 3.7(a).

soon as reasonably practicable after each Calculation Date, but in no event
later than 12:00 noon (New York City time) on the second Business Day prior to

of the Shortfall and the Reserve Account Balance and distribute it to the
Noteholders in payment of the Interest Amount, provided, further that, if the
amount available in the Reserve Account is less than the amount of such
Shortfall, and there is a positive balance in the Capital Account, the Trustee

excess of the Shortfall over the amount, if any, withdrawn from the Reserve
Account and the balance in the Capital Account and distribute it to the
Noteholders in payment of the Interest Amount; provided, that the

such Royalty Payment and distribute such amount in accordance with clauses (i)

total amount of Other Expenses payable under this clause (iii) shall not exceed
$3,500 on any Payment Date;

       

      (iv)           fourth, to Servicer,

prior Payment Date;

       

      (v)           fifth, if a Default
or an Event of Default shall not have occurred and be continuing on such Payment
Date, to the Holding Account, an amount equal to the Issuer’s Allocation of the

after giving effect to the payment on such Payment Date to be equal to
$1,000,000, allocated pro rata in proportion to the Outstanding Principal
Balance of the Notes held by such Noteholders, (b) on each Payment Date
occurring after January 30, 2016 and prior to the Final Maturity Date, to the

amount equal to the Issuer Marketing Payment for the most recently completed
calendar quarter preceding such Payment Date (to the extent Greiner has not
reduced the Royalty Payment for such calendar quarter by the Marketing Payment
for such calendar quarter, as shown in the supporting documentation attached to
the Servicer Information received by the Calculation Agent), which will be
available for distribution to MedPro to be used for the payment of, or for
payment to Greiner on account of, such Marketing Payment;

       

      
        
          
          

        

        
          47

      (x)           tenth, to the Trustee
for distribution to such Persons entitled to the payment of Other Expenses
described in clause (iii) above to the extent not paid pursuant to clause (iii)
above; and

       

      (xi)           eleventh, to the
Issuer, all remaining amounts and the Issuer’s Holding Account Funds, which
amounts shall be available for distribution to MedPro.

       

      (b)           To
the extent the Issuer receives amounts from the Trustee from the Collection
Account pursuant to Section 3.7(a)(xi), such amounts may be distributed by the
Issuer to MedPro (or as otherwise directed by MedPro or any Person designated by
MedPro to give such directions) in its sole discretion.

       

      (c)           In
addition to the foregoing, on the Payment Date occurring on January 30, 2016,
the Issuer shall pay to the Noteholders, as an Incremental Interest Payment, the

Date occurring on or prior to January 30, 2016, to reimburse the Issuer or the

      Section
4.2                                Acceleration, Rescission and
Annulment.

       

      (a)           If
an Event of Default (other than an Acceleration of Default) occurs and is
continuing, the Trustee may, and, upon the Direction of Noteholders of a
majority of the Outstanding Principal Balance of the Notes, shall, give an
Acceleration Notice (and so long as such Acceleration Notice has not been
rescinded and annulled pursuant to this Indenture) to the Issuer. Upon delivery

and unpaid interest thereon shall be immediately due and payable. At any time
after the Trustee or the Noteholders have declared the Outstanding Principal
Balance of the Notes to be immediately due and payable, and prior to the
exercise of any other remedies pursuant to this Indenture, the Trustee, upon the
Direction of Noteholders of a majority of the Outstanding Principal Balance of
the Notes, shall, subject to Section 4.5(a), by written notice to the Issuer and

principal of, the Notes that would have become due otherwise than by such
declaration of acceleration, (ii) the rescission would not conflict with any
judgment or decree and (iii) all other Defaults and Events of Default, other
than non-payment of interest on, and the principal of, the Notes that have
become due solely because of such declaration of acceleration, have been cured
or waived. If an Acceleration Default occurs, the Outstanding Principal Balance
of the Notes and all accrued and unpaid interest thereon shall automatically
become immediately due and payable without any further action by any
party.

the continuation of an Event of Default, no Person other than the Trustee, at
the Direction of a majority of the Outstanding Principal Balance of the Notes,
may give an Acceleration Notice or exercise any remedy in respect of such Event
of Default.

       

      (c)           Within
30 days after the occurrence of an Event of Default, the Trustee shall give to
the Noteholders notice, transmitted by mail, of all uncured or unwaived Defaults
known to it on such date; provided, that the
Trustee may withhold such notice with respect to a Default (other than a payment
default with respect to interest or principal if it determines in good faith
that withholding such notice is in the interest of the affected
Noteholders.

       

      Section
4.3                                Other
Remedies.  Upon the delivery of an Acceleration Notice in
accordance with Section 4.2, or if any Acceleration Default shall have occurred
and be continuing, the Trustee may at all times, but only at the Direction of
Noteholders of a majority of the Outstanding Principal Balance of the Notes,
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on the Notes or to enforce the performance
of any provision of the Notes, this Indenture, the Servicing Agreement, the
MedPro Guarantee or the Pledge and Security Agreement or the other Transaction
Documents or the Manufacturing Agreement, including any of the following, to the
fullest extent permitted by law, subject to the receipt of such
Direction:

       

      (a)           The
Trustee may obtain the appointment of a Receiver of the Indenture Estate as
provided in Section 11.7 and the Issuer consents to and waives any right to
notice of such appointment.

       

      (b)           The
Trustee may, without notice to the Issuer and at such time as the Trustee in its
sole discretion may determine, exercise any or all of the Issuer’s rights in, to
and under or in any way connected with or related to any or all of the Indenture
Estate or the other Transaction Documents or the Manufacturing Agreement,
including (i) demanding and enforcing payment and performance of, and exercising
any or all of the Issuer’s rights and remedies with respect to the collection,
enforcement or prosecution of, any or all of the Indenture Estate (including the
Royalty Rights), in each case, by legal proceedings or otherwise, (ii) settling,
adjusting, compromising, extending, renewing, discharging and releasing any or
all of, and any legal proceedings brought to collect or enforce any or all of,
the Royalty Rights and otherwise under the Transaction Documents or the
Manufacturing Agreement and (iii) preparing, filing and signing the name of the
Issuer on (A) any proof of claim or similar document to be filed in any
bankruptcy or similar proceeding involving the Indenture Estate (including the
Royalty Rights), the Issuer or MedPro and (B) any notice of lien, assignment or
satisfaction of lien, or similar document in connection with the Indenture
Estate (including the Royalty Rights), the Issuer or MedPro.

       

      (c)           The
Trustee may, without notice except as specified herein, sell or cause the sale
of all or any part of the Indenture Estate in one or more parcels at public or
private sale, at any of the Trustee’s offices or elsewhere, for cash, on credit
or for future delivery, and upon such other terms as the Trustee may deem
commercially reasonable. The Issuer agrees that, to the extent notice of sale
shall be required by law, at least ten days’ notice to the Issuer 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 Trustee shall not
be obligated to make any sale of all or any part of the Indenture Estate
regardless of notice of sale having been given. The Trustee 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.

       

      
        
          
          

        

        
          51

          
            

          

        

        
          
          

        

      

       

      (d)           The
Trustee may, instead of exercising the power of sale conferred upon it by
Section 4.3(c) and Applicable Law, proceed by a suit or suits at law or in
equity to foreclose the Security Interest and sell all or any portion of the
Indenture Estate under a judgment or a decree of a court or courts of competent
jurisdiction.

       

      (e)           The
Trustee may require the Issuer to, and the Issuer hereby agrees that it shall at
its expense and upon request of the Trustee, forthwith assemble all or part of
the Indenture Estate as directed by the Trustee and make it available to the
Trustee at a place to be designated by the Trustee that is reasonably convenient
to both parties.

       

      (f)           In
addition to the rights and remedies provided for in this Indenture, the Trustee
may exercise in respect of the Indenture Estate all the rights and remedies of a
secured party upon default under the UCC (whether or not the UCC applies to the
affected property included in the Indenture Estate) and under all other
Applicable Law.

       

      (g)           The
Trustee may maintain a proceeding even if it does not possess any of the Notes
or does not produce any of them in the proceeding.

       

      Section
4.4                                Limitation on
Suits.  Without limiting the provisions of Section 4.9 and the
final sentence of Section 11.4, no Noteholder shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, the
MedPro Guarantee, the Pledge and Security Agreement or the Notes, for the
appointment of a receiver or trustee or for any other remedy hereunder,
unless:

       

      (a)           such
Noteholder has previously given written notice to the Trustee of a continuing
Event of Default;

       

      (b)           the
Noteholders of a majority of the Outstanding Principal Balance of the Notes make
a written request to the Trustee to pursue a remedy hereunder;

       

      (c)           such
Noteholder or Noteholders offer to the Trustee an indemnity reasonably
satisfactory to the Trustee against any costs, expenses and liabilities to be
incurred in complying with such request;

       

      (d)           the
Trustee does not comply with such request within 60 days after receipt of the
request and the offer of indemnity; and

       

      (e)           during
such 60-day period, Noteholders of a majority of the Outstanding Principal
Balance of the Notes do not give the Trustee a Direction inconsistent with such
request.

       

      
        
          
          

        

        
          52

          
            

          

        

        
          
          

        

      

       

      No one or
more Noteholders may use this Indenture to affect, disturb or prejudice the
rights of another Noteholder or to obtain or seek to obtain any preference or
priority not otherwise created by this Indenture and the terms of the Notes over
any other Noteholder or to enforce any right under this Indenture, except in the
manner herein provided.

       

      Section
4.5                                Waiver of Existing
Defaults.

       

      (a)           The
Trustee or the Noteholders of a majority of the Outstanding Principal Balance of
the Notes by written notice to the Trustee may waive any existing Default (or
Event of Default) hereunder and its consequences, except a Default (or Event of
Default) (i) in the payment of the interest on, and principal of, any Note or
(ii) in respect of a covenant or provision hereof which under Article IX cannot
be modified or amended without the consent of the Noteholder of each Note
affected thereby. Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture, but no such waiver shall extend to any
subsequent or other Default (or Event of Default) or impair any right consequent
thereon.

       

      (b)           Any
written waiver of a Default or an Event of Default given by Noteholders to the
Trustee and the Issuer in accordance with the terms of this Indenture shall be
binding upon the Trustee and the other parties hereto. Unless such writing
expressly provides to the contrary, any waiver so granted shall extend only to
the specific event or occurrence which gave rise to the Default or Event of
Default so waived and not to any other similar event or occurrence which occurs
subsequent to the date of such waiver.

       

      Section
4.6                                Restoration of Rights and
Remedies.  If the Trustee or any Noteholder has instituted any
proceeding to enforce any right or remedy under this Indenture, and such
proceeding has been discontinued or abandoned for any reason or has been
determined adversely to the Trustee or such Noteholder, then in every such case
the Issuer, the Trustee and the Noteholders shall, subject to any determination
in such proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Trustee and
the Noteholders shall continue as though no such proceeding has been
instituted.

       

      Section
4.7                                Remedies
Cumulative.  Each and every right, power and remedy herein
given to the Trustee specifically or otherwise in this Indenture shall be
cumulative and shall, to the extent permitted by law, be in addition to every
other right, power and remedy herein specifically given or now or hereafter
existing at law, in equity or by statute, and each and every right, power and
remedy whether specifically herein given or otherwise existing may be exercised
from time to time and as often and in such order as may be deemed expedient by
the Trustee, and the exercise or the beginning of the exercise of any power or
remedy shall not be construed to be a waiver of the right to exercise at the
same time or thereafter any other right, power or remedy. No delay or omission
by the Trustee in the exercise of any right, remedy or power or in the pursuance
of any remedy shall impair any such right, power or remedy or be construed to be
a waiver of any Default on the part of the Issuer or to be an
acquiescence.

       

      Section
4.8                                Authority of Courts Not
Required.  The parties hereto agree that, to the greatest
extent permitted by law, the Trustee shall not be obliged or required to seek or
obtain the authority of, or any judgment or order of, the courts of any
jurisdiction in order to exercise any of its rights, powers and remedies under
this Indenture, and the parties hereby waive any such requirement to the
greatest extent permitted by law.

       

      
        
          
          

        

        
          53

          
            

          

        

        
          
          

        

      

       

      Section
4.9                                Rights of Noteholders to
Receive Payment.  Notwithstanding any other provision of this
Indenture, the right of any Noteholder to receive payment of interest on, or
principal of, any Note on or after the respective due dates therefor expressed
in such Note, or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the
consent of such Noteholder.

       

      Section
4.10                                Trustee May File Proofs of
Claim.  The Trustee may file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee and of any Noteholder allowed in any judicial proceedings
relating to any obligor on the Notes, its creditors or its
property.

       

      Section
4.11                                Undertaking for
Costs.  All parties to this Indenture agree, and each
Noteholder by its acceptance hereof shall be deemed to have agreed, that, in any
suit for the enforcement of any right or remedy under this Indenture or in any
suit against the Trustee for any action taken or omitted by it as Trustee, a
court in its discretion may require the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defense made by the party litigant. This Section
4.11 does not apply to a suit instituted by the Trustee, a suit instituted by
any Noteholder for the enforcement of the payment of interest or principal on
any Note on or after the respective due dates expressed in such Note or a suit
by a Noteholder or Noteholders of at least 10% of the Outstanding Principal
Balance of the Notes.

       

      Section
4.12                                Control by
Noteholders.  Subject to Section 4.2 and Section 4.4 and to the
rights of the Trustee hereunder, Noteholders of a majority of the Outstanding
Principal Balance of the Notes shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee under this Indenture;
provided,
that:

       

      (a)           such
Direction shall not be in conflict with any rule of law or with this Indenture
and would not involve the Trustee in personal liability or expense;

       

      (b)           the
Trustee shall not determine that the action so directed would be unjustly
prejudicial to the Noteholders not taking part in such Direction;
and

       

      (c)           the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such Direction.

       

      Section
4.13                                Application of
Proceeds.  All cash proceeds received by the Trustee in respect
of any sale of, collection from or other realization upon all or any part of the
Indenture Estate, the MedPro Guarantee or the other Transaction Documents shall
be deposited in the Collection Account and distributed as provided in Article
III. Any surplus of such cash proceeds held by the Trustee and remaining after
payment in full of all Secured Obligations shall be paid over to the Issuer or
whomsoever may be lawfully entitled to receive such surplus as provided in
Section 3.7. Any amount received for any sale or sales conducted in accordance
with the terms of Section 4.3 shall to the extent permitted by Applicable Law be
deemed conclusive and binding on the Issuer and the Noteholders.

      Section
4.14                                Waivers of Rights Inhibiting
Enforcement.  The Issuer waives (a) any claim that, as to any
part of the Indenture Estate, a public sale, should the Trustee elect so to
proceed with a private sale thereof, the mere fact that such a sale is a private
sale does not in and of itself, mean that such sale is not a commercially
reasonable method of sale for such part of the Indenture Estate, (b) the right
to assert in any action or proceeding between it and the Trustee offsets or
counterclaims that it may have, (c) except as otherwise provided in any of the
Transaction Documents, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE OR
JUDICIAL HEARING IN CONNECTION WITH THE TRUSTEE’S TAKING POSSESSION OR
DISPOSITION OF ANY OF THE INDENTURE ESTATE, INCLUDING ANY AND ALL PRIOR NOTICE
AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT THAT THE
ISSUER WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE U.S. OR
OF ANY STATE, AND ALL OTHER REQUIREMENTS AS TO THE TIME, PLACE AND TERMS OF SALE
OR OTHER REQUIREMENTS WITH RESPECT TO THE ENFORCEMENT OF THE TRUSTEE’S RIGHTS
HEREUNDER, (d) all rights of redemption, appraisement, valuation, stay and
extension or moratorium and (e) except as otherwise provided in any of the
Transaction Documents, all other rights the exercise of which would, directly or
indirectly, prevent, delay or inhibit the enforcement of any of the rights or
remedies under this Indenture or the absolute sale of the Indenture Estate, now
or hereafter in force under any Applicable Law, and the Issuer, for itself and
all who may claim under it, insofar as it or they now or hereafter lawfully may,
hereby waives the benefit of all such laws and rights.

       

      Section
4.15                                Security Interest
Absolute.  All rights of the Trustee and security interests
hereunder, and all obligations of the Issuer hereunder, shall be absolute and
unconditional irrespective of, and the Issuer hereby irrevocably waives any
defenses it may now have or may hereafter acquire in any way relating to, any or
all of the following:

       

      (a)           any
lack of validity or enforceability of any of the Transaction Documents or any
other agreement or instrument relating thereto (other than against the
Trustee);

       

      (b)           any
change in the time, manner or place of payment of, or in any other term of, all
or any of the Secured Obligations, or any other amendment or waiver of or any
consent to any departure from the Transaction Documents or any other agreement
or instrument relating thereto;

       

      (c)           any
taking, exchange, surrender, release or non-perfection of any Collateral or any
other collateral, or any release or amendment or waiver of or consent to any
departure from any guaranty, for all or any of the Secured
Obligations;

       

      
        
          
          

        

        
          55

          
            

          

        

        
          
          

        

      

       

      (d)           any
manner of application of any Collateral or any other collateral, or proceeds
thereof, to all or any of the Secured Obligations, or any manner of sale or
other disposition of any Collateral or any other collateral for all or any of
the Secured Obligations or any other obligations of the Issuer under or in
respect of the Transaction Documents or any other assets of the
Issuer;

       

      (e)           any
change, restructuring or termination of the limited liability company structure
or existence of the Issuer;

       

      (f)           the
failure of any other Person to execute this Indenture or any other agreement or
the release or reduction of liability of the Issuer or other grantor or surety
with respect to the Secured Obligations; or

       

      (g)           any
other circumstance (including any statute of limitations) or any existence of or
reliance on any representation by the Trustee that might otherwise constitute a
defense available to, or a discharge of, the Issuer.

AND COVENANTS

constitute a default under the organizational documents of the Issuer or with
any existing law, rule or regulation applying to or affecting the Issuer or any
judgment, order or decree of any government, governmental body or court having

      (d)           The
creation, execution and issuance of the Notes, the execution and delivery by the
Issuer of the Transaction Documents executed by it and the performance by the
Issuer of its obligations hereunder and thereunder and the arrangements
contemplated hereby and thereby to be performed by it have been duly authorized,
executed and delivered by the Issuer.

       

      (e)           This

reasonableness, good faith and fair dealing) enforceable obligations of the
Issuer.

       

      (f)           There
exists no Event of Default nor any event which, had the Notes already been
issued, would constitute a Default or an Event of Default.

Authorities required (excluding any required by the other parties to the
Transaction Documents) for or in connection with the execution, delivery and
performance of the Transaction Documents by the Issuer and the issuance and
performance of the Notes and the offering of the Notes by the Issuer have been
obtained and are in full force and effect and are not contingent upon
fulfillment of any condition.  No consent of any Governmental
Authority or any other party (including directors, officers, members, managers
or creditors of the Issuer) is required that has not been obtained for the
pledge by the Issuer of the Collateral pursuant to this Indenture

       

      (i)           The
Issuer is not required to register as an “investment company” within the meaning
of the Investment Company Act of 1940, as amended.

federal incomes tax purposes.

       

      (m)           The
Issuer is the sole legal and beneficial owner of the Royalty Rights, free and

      (n)           It
is not necessary that this Indenture or any other Transaction Document (other
than evidences and perfection of the Security Interests) be filed, recorded or

jurisdictions or that any stamp, registration or similar tax be paid by the
Issuer on or in relation to this Indenture or any of the other Transaction
Documents (other than filings of Uniform Commercial Code financing statements
set forth in Exhibit
K and the various consents and agreements, if any, pursuant
hereto).

required to perfect a security interest in favor of the Trustee in the Royalty
Rights sold, transferred, conveyed, assigned, contributed and granted on the
Closing Date and the Collateral, including those specified in Exhibit K, if any,
have been or shall have been duly made by the Closing Date, and the Trustee has
or shall have the same rights as MedPro has or would have with respect to the
Royalty Rights (if MedPro were still the owner of such Royalty Rights) against
Greiner.  No other security agreement, financing statement or other
public notice with respect to all or any part of the Collateral (other than any
of the foregoing that is referenced in Exhibit B to the
Purchase and Sale Agreement or Exhibit K to
this Indenture or otherwise names the Trustee as secured party) is on file or of
record in any public office that perfects a valid security interest
therein.  This Indenture creates a valid security interest in the
Collateral securing the payment of the Secured Obligations.

       

      (p)           The
Issuer has determined, and by virtue of its entering into the transactions
contemplated hereby and its authorization, execution and delivery of this
Indenture and the other Transaction Documents to which it is party, that the
issuance of the Notes and the consummation of the transactions contemplated
hereby and thereby, and its incurrence of Indebtedness and other liability
hereunder or thereunder or contemplated hereby or thereby (i) is in its own best
interests, (ii) does not leave it unable to pay its debts as they become due in
the ordinary course of business, (iii) will not leave it with debts that cannot
be paid from the present saleable value of its property and (iv) will not render
it insolvent within the meaning of Section 101(32) of the United States
Bankruptcy Code or Section 271 of the New York Debtor and Creditor Law or leave
it with unreasonably small capital.

       

      (q)           No
material adverse change in the business, condition (financial or otherwise),
performance or properties of the Issuer has occurred since its date of
formation.

       

      (r)           No
step has been taken or is intended by the Issuer or, so far as it is aware, any
other Person for the winding-up, liquidation, dissolution, administration,
merger or consolidation or for the appointment of a receiver or administrator of
the Issuer or all or any of its assets.

       

      (s)           The
Issuer has not assigned or pledged any of its right, title or interest in the
Collateral to anyone other than the Trustee.

       

      (t)           The
representations and warranties made by the Issuer in any of the other
Transaction Documents to which it is a party are true and accurate as of the
date made.

      Section
5.2                                Covenants.  The
Issuer covenants with the Trustee that, so long as any Notes are Outstanding, it
will perform and comply with each of the following covenants and not engage in
any activity prohibited by this Indenture without the prior written consent of
the Trustee (acting at the Direction of the Note holders of a majority of the
Outstanding Principal Balance of the Notes) authorizing the Issuer not to
perform any such covenants or to engage in any such activity prohibited by this
Indenture, in each case on such terms and conditions, if any, as shall be
specified in such prior written consent:

       

      (a)           Except
as expressly permitted by this Indenture, the Issuer shall not take any action,
whether orally or in writing, which would amend, waive, modify, supplement,
restate, cancel or terminate or discharge or prejudice the validity or
effectiveness of any Transaction Document, or permit any party to any such
document to be released from such obligations.

       

      (b)           The
Issuer shall not, directly or indirectly, (i) declare or pay any dividend or
make any distribution on its Stock, whether in cash, property, securities or a
combination thereof, to MedPro or any owner of a beneficial interest in the
Issuer or otherwise with respect to any ownership of its Stock, except that the
Issuer may distribute to MedPro the balance, if any, Wing Reserve Account in
accordance with Section 3.4(c) and all or any portion of any amounts transferred
to the Issuer pursuant to Section 3.7(a)(xi), (ii) purchase, redeem, retire or
otherwise acquire for value any shares of Stock of the Issuer or any of its
Affiliates, (iii) make any payment of principal or interest on the Notes or make
any voluntary or optional redemption, repurchase, defeasance or other
acquisition or retirement for value of, or make any deposit (including the
payment of amounts into a sinking fund or other similar fund) with respect to,
Indebtedness of the Issuer other than in accordance with the Notes and this
Indenture or (iv) make any loan or advance to a Person, any purchase or other
acquisition of any beneficial interest, capital stock, warrants, rights,
options, obligations or other securities of such Person, any capital
contribution to such Person or any other investment in such Person (other than
Eligible Investments and investments permitted under Section
5.2(f)).

       

      (c)           The
Issuer shall not (and shall not consent to MedPro taking any action that would)
incur or suffer to exist any Encumbrance over or with respect to any of the
Issuer’s assets, other than any Permitted Encumbrance.

       

      (d)           The
Issuer shall not incur, create, issue, assume, Guarantee or otherwise become
liable for or with respect to, or become responsible for, the payment of or
performance of, contingently or otherwise, whether present or future (in any
such case, to “Incur”),
Indebtedness; provided, however, that the
Issuer may Incur Indebtedness in respect of the Notes.

       

      (e)           The
Issuer shall not liquidate or dissolve, consolidate with, merge with or into, or
sell, convey, transfer, lease or otherwise dispose of the Royalty Rights or all
or any material portion of its other property and assets to, or purchase or
otherwise acquire all or substantially all of the assets of, any other Person,
or permit any other Person to merge with or into, or consolidate or otherwise
combine with, the Issuer.

       

      
        
          
          

        

        
          59

          
            

          

        

        
          
          

        

      

       

      (f)           The
Issuer shall not, directly or indirectly, issue, deliver or sell, or consent to
issue, deliver or sell, any actual, contingent, future or executory membership
interests, limited liability company interests, beneficial interests or other
equity or ownership interests (however designated, whether voting or non-voting,
except for any additional Stock of the Issuer issued to MedPro, provided that such
additional Stock is pledged to the Trustee pursuant to the Pledge and Security
Agreement, and provided, further that the
Issuer shall not accept any capital contributions from MedPro after the Closing
Date except for contributions of funds deposited into the Capital Account, which
may be used only as provided in Section 3.1(g).

       

      (g)           Except
as otherwise provided in the LLC Operating Agreement, the Issuer shall not

Issuer shall not, directly or indirectly, enter into, renew or extend any
transaction (including the purchase, sale, lease or exchange of property or
assets, or the rendering of any service) with any Affiliate of the Issuer,
except upon fair and reasonable terms no less favorable to the Issuer than could
be obtained, at the time of such transaction or at the time of the execution of
the agreement providing therefor, in a comparable arm’s-length transaction with
a Person that is not such an Affiliate. The parties expressly agree that each
Transaction Document satisfies the provisions of this Section
5.2(h).

       

      (i)           The
Issuer shall not take any action to become subject to any proceeding of the type
described in Section 4.1(f) or (g).  The Issuer shall promptly provide
the Trustee with written notice of the institution of any proceeding by or
against the Issuer seeking to adjudicate it a bankrupt or insolvent, or seeking
liquidation, winding-up, reorganization, arrangement, adjustment, protection,
relief or composition of its debts under any law relating to bankruptcy,
insolvency or reorganization or relief of debtors, or seeking the entry of an
order for relief or the appointment of a receiver, trustee or other similar
official for it or for any substantial part of its property. The Issuer shall
not take any action to waive, repeal, amend, vary, supplement or otherwise
modify its organizational documents in a manner that would adversely affect the
rights, remedies, privileges or preferences of any Noteholder, the Collateral or
the Royalty Rights.  The Issuer shall not, without an affirmative
written resolution of all of the Members and the unanimous consent of all of the
Managers (including the Independent Manager), take any action to waive, repeal,
amend, vary, supplement or otherwise modify any provision of the LLC Operating
Agreement that requires unanimous written consent of the Members or the Managers
or limits the actions of MedPro with respect to voluntary insolvency proceedings
or consents to involuntary proceedings.  The Issuer shall comply with,
and cause compliance with, its certificate of formation and the LLC Operating
Agreement.

       

      (j)           The
Issuer shall duly and punctually pay the principal and interest on the Notes in
accordance with the terms of this Indenture and the Notes; provided, that the
Issuer shall be in compliance with this covenant if it pays in full by the next
succeeding Payment Date any Interest Amount on the Notes (including Additional
Interest thereon) that became due and was not paid on any Payment Date, other
than the Final Maturity Date.

      (k)           The
Issuer shall not employ any employees other than as required by any provisions
of local law [or as contemplated by the LLC Operating Agreement]; provided, that the
Members, the Manager and Service Providers shall not be deemed to be employees
for purposes of this Section 5.2(k).

       

      (l)           During
any period in which the Issuer is not subject to Section 13 or 15(d) of the
Exchange Act, the Issuer shall make available to any Noteholder or Beneficial
Holder in connection with any sale of any or all of its Notes and any
prospective purchaser of such Notes from such Noteholder or Beneficial Holder
the information required by Rule 144A(d)(4) under the Securities
Act.

       

      (m)           The
Issuer shall not enter into any new agreement in respect of the Royalty Rights
or the Product or exercise or waive any right or option, fail to exercise any
right or option or grant any consent in respect of the Royalty Rights or the
Product in any manner that would, in each case, materially adversely affect the
Issuer, the Issuer’s rights under the Purchase and Sale Agreement or the rights
and interests of the Trustee and the Noteholders with respect thereto or the
Noteholders or conflict with or cause an Event of Default under, or breach of
this Indenture or any other Transaction Document.

       

      (n)           The
Issuer shall at all times enforce its rights and remedies under the Purchase and
Sale Agreement and the Servicing Agreement in a timely and commercially
reasonable manner; provided, that, following the occurrence and continuation of
a Default or an Event of Default, the Issuer shall give written notice to the
Trustee on behalf of the Noteholders of any contemplated enforcement of such
rights and remedies and will follow any commercially reasonable direction of the
Trustee at the Direction of Noteholders of a majority of the Outstanding
Principal Balance of the Notes.

Collateral hereby assigned to anyone other than the Trustee.

       

      (s)           The
Issuer agrees that, at any time and from time to time, at the Issuer’s expense,
the Issuer will promptly and duly execute and deliver or cause to be duly

that no such designation or rescission shall in any manner relieve the Issuer of
its obligation to maintain an office or agency in the Borough of Manhattan, The
City of New York, for such purposes.

of the Issuer’s compliance with all of its obligations under this Indenture (it
being understood that, for purposes of this Section 5.3, such compliance shall
be determined without regard to any period of grace or requirement of notice
provided under this Indenture but shall reflect any interest paid on the Notes
by the next succeeding Payment Date as contemplated by the proviso to Section
5.2(j)).

       

      (b)           The
Issuer shall deliver written notice to the Trustee of the occurrence of (i) any

Issuer shall only deliver such materials to the Trustee to the extent such
materials do not contain Confidential Information of Greiner.

       

      (d)           Within
120 days after the beginning of each fiscal year commencing with the fiscal year
beginning January 1, 2011, the Issuer shall furnish to the Trustee an opinion of
its legal counsel, which opinion shall state whether there are any actions to be
taken, including any financing statements to be filed in any office, within the
period of 12 full consecutive calendar months following the date of such opinion

Transaction Documents or to continue the effectiveness of any financing
statements filed in connection with the Transaction Documents as of the date
hereof.  Notwithstanding Section 5.3(c), the Issuer shall furnish
Confidential Information of Greiner to the Trustee for distribution to
Noteholders to the extent such distribution is permitted by Section
6.2.

      (b)           The
Trustee has all requisite right, power and authority to execute and deliver this
Indenture and its related documents and to perform all of its duties as Trustee
hereunder and thereunder.

       

      (c)           The
execution and delivery by the Trustee of this Indenture and the other
Transaction Documents to which it is a party, and the performance by the Trustee
of its duties hereunder and thereunder, have been duly authorized by all

similar laws relating to or affecting the enforcement of creditors’ rights
generally and (ii) the availability of equitable remedies may be limited by
equitable principles of general applicability.

       

      Section
6.4                                Reliance; Agents; Advice of
Counsel.  The Trustee shall incur no liability to anyone acting
upon any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties. The
Trustee may accept a copy of a resolution of, in the case of the Issuer, the
Manager and, in the case of any other party to any Transaction Document, the
governing body of such Person, certified in an accompanying Officer’s
Certificate as duly adopted and in full force and effect, as conclusive evidence
that such resolution has been duly adopted and that the same is in full force
and effect. As to any fact or matter the manner of ascertainment of which is not
specifically described herein, the Trustee shall be entitled to receive and may
for all purposes hereof conclusively rely on a certificate, signed by an officer
of any duly authorized Person, as to such fact or matter, and such certificate
shall constitute full protection to the Trustee for any action taken or omitted
to be taken by it in good faith in reliance thereon. To the extent not otherwise
specifically provided herein, the Trustee shall assume, and shall be fully
protected in assuming, that the Issuer is authorized by its constitutional
documents to enter into this Indenture and to take all action permitted to be
taken by it pursuant to the provisions hereof and shall not be required to
inquire into the authorization of the Issuer with respect thereto. To the extent
not otherwise specifically provided herein, the Trustee shall furnish to
Servicer upon written request such information and copies of such documents as
the Trustee may have and as are necessary for Servicer to perform its duties
under Article II and Article III or otherwise.

      The
Trustee shall not be liable for any action it takes or omits to take in good
faith that it believes to be authorized or within its rights or powers or for
any action it takes or omits to take in accordance with the Direction of the
Noteholders in accordance with Section 4.12 relating to the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under this
Indenture.

       

      The
Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys or a custodian or
nominee, and the Trustee shall not be responsible for any misconduct or
negligence on the part of, or for the supervision of, any such agent, attorney,
custodian or nominee appointed with due care by it hereunder.

       

      The
Trustee may consult with counsel as to any matter relating to this Indenture and
any Opinion of Counsel or any advice of such counsel shall be full and complete
authorization and protection in respect of any action taken or suffered or
omitted by it hereunder in good faith and in accordance with such advice or
Opinion of Counsel.

       

      The
Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture, or to institute, conduct or defend any
litigation hereunder or in relation hereto, at the request, order or Direction
of any of the Noteholders, pursuant to the provisions of this Indenture, unless
such Noteholders shall have offered to the Trustee security or indemnity
reasonably satisfactory to it against the costs, expenses and liabilities which
may be incurred therein or thereby.

       

      The
Trustee shall not be required to expend or risk its own funds or otherwise incur
any financial liability in the performance of any of its duties hereunder, or in
the exercise of any of its rights or powers, if there is reasonable ground for
believing that the repayment of such funds or indemnity satisfactory to it
against such risk or liability is not reasonably assured to it, and none of the
provisions contained in this Indenture shall in any event require the Trustee to
perform, or be responsible or liable for the manner of performance of, any
obligations of the Issuer or Servicer under this Indenture or any of the other
Transaction Documents.

       

      The
Trustee shall not be liable for any Losses or Taxes (except for Taxes relating
to any compensation, fees or commissions of any entity acting in its capacity as
Trustee hereunder) or in connection with the selection of Eligible Investments
or for any investment losses resulting from Eligible Investments.

       

      When the
Trustee incurs expenses or renders services in connection with an Event of
Default specified in Section 4.1(e) or Section 4.1(f), such expenses (including
the fees and expenses of its counsel) and the compensation for such services are
intended to constitute expenses of administration under any bankruptcy law or
law relating to creditors’ rights generally.

      The
Trustee shall not be charged with knowledge of an Event of Default unless a
Responsible Officer of the Trustee obtains actual knowledge of such event or has
received written notice of such event from the Issuer, Servicer or Noteholders
of not less than 10% of the Outstanding Principal Balance of the
Notes.

       

      The
Trustee shall have no duty to monitor the performance of the Issuer, Servicer or
any other party to the Transaction Documents, nor shall it have any liability in
connection with the malfeasance or nonfeasance by such parties.

       

      Whenever
in the administration of the provisions of this Indenture the Trustee shall deem
it necessary or desirable that a matter be proved or established prior to taking
or suffering any action to be taken hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the
absence of gross negligence or bad faith on the part of the Trustee, be deemed
to be conclusively proved and established by a certificate signed by a
Responsible Officer of the Issuer and delivered to the Trustee, and such
certificate, in the absence of gross negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted by it under the provisions of this Indenture upon the faith
thereof.

       

      Except as
provided expressly hereunder, the Trustee shall have no obligation to invest and
reinvest any cash held in the Accounts in the absence of timely and specific
written investment direction by or on behalf of the Issuer. In no event shall
the Trustee be liable for the selection of investments or for investment losses
incurred thereon. The Trustee shall have no liability in respect of losses
incurred as a result of the liquidation of any investment prior to its stated
maturity or the failure of the Issuer to provide timely written investment
direction.

       

      When the
Trustee incurs expenses after the occurrence of a Default specified in Section
4.1 with respect to the Issuer, if the surviving entity has failed to honor such
obligation, the expenses are intended to constitute expenses of administration
under any insolvency law or under Title 11 of the United States
Code.

       

      Section
6.5                                Not Acting in Individual
Capacity.  The Trustee acts hereunder solely as trustee unless
otherwise expressly provided, and all Persons, other than the Noteholders to the
extent expressly provided in this Indenture, having any claim against the
Trustee by reason of the transactions contemplated hereby shall look, subject to
the lien and priorities of payment as herein provided, only to the property of
the Issuer for payment or satisfaction thereof

       

      Section
6.6                                Compensation of
Trustee.  The Trustee agrees that it shall have no right
against the Noteholders or, except as provided in Section 3.5(a) or Section
3.7(a), the property of the Issuer, for any fee as compensation for its services
hereunder. The Issuer shall pay to the Trustee from time to time such
compensation as is agreed between the two parties. The compensation shall be
paid to the Trustee as provided in Section 3.5(a) and Section
3.7(a).

      Section

Defaults.  As promptly as practicable after, and in any event
within 30 days after, the occurrence of any Default hereunder, the Trustee shall
transmit by mail to the Issuer and the Noteholders, in accordance with Section
313(c) of the Trust Indenture Act, notice of such Default hereunder actually
known to a Responsible Officer of the Trustee, unless such Default shall have
been cured or waived; provided, however, that, except in the case of a Default
on the payment of the interest or principal on any Note, the Trustee shall be
fully protected in withholding such notice if and so long as a trust committee
of Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Noteholders.

       

      Section
6.8                                May Hold
Notes.  The Trustee, any Paying Agent, the Registrar or any of
their Affiliates or any other agent in their respective individual or any other
capacity may become the owner or pledgee of the Notes and, subject to Sections
310(b) and 311 of the Trust Indenture Act, may otherwise deal with the Issuer
with the same rights it would have if it were not the Trustee, Paying Agent,
Registrar or such other agent.

       

      Section
6.9                                Corporate Trustee Required;
Eligibility.  There shall at all times be a Trustee which shall
be eligible to act as a trustee under Section 310(a) of the Trust Indenture Act
and shall meet the Eligibility Requirements. If such corporation publishes
reports of conditions at least annually, pursuant to law or to the requirements
of any federal, state, foreign, territorial or District of Columbia supervising
or examining authority, then, for the purposes of this Section 6.9, the combined
capital and surplus of such corporation shall be deemed to be its combined

published.

       

      In case
at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 6.9 to act as Trustee, the Trustee shall resign
immediately as Trustee in the manner and with the effect specified in Section
7.1.

Issuer shall have the right to inspect and make copies of all such Supplemental
Confidentiality Agreements at any reasonable time upon the giving of reasonable
written notice to the Registrar. Forms of Supplemental Confidentiality

the State of New York. Except as permitted by this Section 6.14, the Trustee
shall not hold any part of the Indenture Estate through an agent or a

of Noteholder Lists.  The Registrar shall preserve, in as
current a form as is reasonably practicable, all information as to the names and
addresses of the Noteholders received by it. At any time when a default or an
Event of Default has occurred and is continuing, in case either (a) three or
more Noteholders that have executed and delivered to the Registrar a
Confidentiality Agreement or (b) one or more Noteholders of at least 25% of the
Outstanding Principal Balance of the Notes that have executed and delivered to
the Registrar a Confidentiality Agreement (in each case, “Applicants”) apply in
writing to the Registrar and furnish to the Registrar reasonable proof that each
such Applicant has owned a Note for a period of at least three months preceding
the date of such application, and such application states that the Applicants
desire to communicate with other Noteholders with respect to their rights under
this Indenture or under the Notes and such application is accompanied by a copy
of the form of proxy or other communication which such Applicants propose to
transmit, then the Registrar shall, within five Business Days after the receipt
of such application, inform such Applicants as to the approximate number of
Noteholders whose names and addresses appear in such information and as to the
approximate cost of mailing to such Noteholders the form of proxy or other
communication, if any, specified in such application. The Registrar shall, upon
the written request of such Applicants, mail to each Noteholder whose name and
address appears in such information a copy of the form of proxy or other
communication which is specified in such request, with reasonable promptness
after a tender to the Registrar of the material to be mailed and of payment, or
provision for the payment, of the reasonable expenses of mailing. Each and every
Noteholder, by receiving and holding the same, agrees with the Issuer and the
Registrar that neither the Registrar nor any agent of the Issuer or the
Registrar shall be held accountable by reason of mailing any material pursuant
to a request made under this Section 6.15.

      (a)           In
the case of the resignation or removal of the Trustee under Section 7.1, the
Issuer shall promptly appoint a successor Trustee; provided, that the
Noteholders of a majority of the Outstanding Principal Balance of the Notes may
appoint, within one year after such resignation or removal, a successor Trustee
which may be other than the successor Trustee appointed by the Issuer, and such
successor Trustee appointed by the Issuer shall be superseded by the successor
Trustee so appointed by the Noteholders. If a successor Trustee shall not have
been appointed and accepted its appointment hereunder within 60 days after the
Trustee gives notice of resignation, the retiring Trustee, the Issuer, Servicer
or a majority of the Outstanding Principal Balance of the Notes may petition any

further act be superseded by any successor Trustee appointed as provided in the
first sentence of this paragraph within one year from the date of the
appointment by such court.

and thereupon such successor Trustee, without further act, shall become vested
with all the estates, properties, rights, powers, duties and trusts of such
predecessor Trustee hereunder in the trusts hereunder applicable to it with like
effect as if originally named the Trustee herein; provided, that, upon
the written request of such successor Trustee, such predecessor Trustee shall,
upon payment of all amounts due and owing to it, execute and deliver an
instrument transferring to such successor Trustee, upon the trusts herein
expressed applicable to it, all the estates, properties, rights, powers and
trusts of such predecessor Trustee, and such predecessor Trustee shall duly
assign, transfer, deliver and pay over to such successor Trustee all moneys or
other property then held by such predecessor Trustee hereunder solely for the
benefit of the Notes.

       

      (c)           Each
Trustee shall be an Eligible Institution and shall meet the Eligibility
Requirements, if there be such an institution willing, able and legally
qualified to perform the duties of a Trustee hereunder.

consolidation to which the Trustee shall be a party, or any Person to which all
or substantially all of the corporate trust business of the Trustee (including
the administration of the trust created by this Indenture) may be transferred,

be furnished hereunder. The Trustee shall notify the Issuer promptly of any
claim asserted against the Trustee for which it may seek indemnity; provided, however, that failure
to provide such notice shall not invalidate any right to indemnity hereunder.
The Issuer shall defend any such claim and the Trustee shall cooperate in the
defense thereof.  The Trustee may have separate counsel and the Issuer
shall pay the reasonable fees and expenses of one separate outside counsel for
the Trustee. The Issuer need not pay for any settlements made without its
consent; provided, that such
consent shall not be unreasonably withheld or delayed. The Issuer need not
reimburse any expense or provide any indemnity against any loss, liability or
expense incurred by the Trustee through bad faith, gross negligence or willful
misconduct.

indemnified by the Noteholders before proceeding to exercise any right or power
under this Indenture at the request or Direction of such
Noteholders.

      MODIFICATION

       

      Section
9.1                                Modification with Consent of
Noteholders.  With the consent of Noteholders of a majority of
the Outstanding Principal Balance of the Notes on the date of any vote or act of
such Noteholders, the Issuer, when authorized by a Manager Resolution, may amend
or modify this Indenture, the Notes, the Pledge and Security Agreement, the
Purchase and Sale Agreement, the Bill of Sale, the MedPro Guarantee or the
Servicing Agreement or to consent to the amendment or modification of the Pledge
and Security Agreement, the Purchase and Sale Agreement, the Bill of Sale, the
MedPro Guarantee or the Servicing Agreement (or the waiver of any provision
thereof) or the Notes. However, no amendment or modification of this Indenture,
the Notes, the Pledge and Security Agreement or the MedPro Guarantee may,
without the consent of Noteholders of 100% of the Outstanding Principal Balance
of the Notes affected thereby:

       

      (a)           reduce
the percentage of Noteholders required to take or approve any action hereunder
or thereunder;

       

      (b)           reduce
the amount or change the time of payment of any amount owing or payable with
respect to the Notes or change the rate of interest or change the manner of
calculation of interest payable with respect to the Notes;

       

      (c)           alter
or modify in a manner adverse to the Noteholders the provisions with respect to
the Collateral for the Notes or the MedPro Guarantee or the Pledge and Security
Agreement or the manner of payment or the order of priorities in which payments
or distributions hereunder will be made as between the Noteholders of such Notes
and the Issuer or as among the Noteholders; or

       

      
        
          
          

        

        
          73

          
            

          

        

        
          
          

        

      

       

      (d)           consent
to any assignment of the Issuer’s rights to a party other than the Trustee for
the benefit of the Noteholders;

       

      provided, that the
Noteholders of a majority of the Outstanding Principal Balance of the Notes, by
written notice to the Trustee, may waive any Default or Event of Default
pursuant to Section 4.5.

       

      It shall
not be necessary for the consent of the Noteholders under this Section 9.1 to
approve the particular form of any proposed amendment or waiver, but it shall be
sufficient if such consent approves the substance thereof.  Any such
modification approved by the required Noteholders will be binding on all
Noteholders and each party to this Indenture.

       

      After an
amendment under this Section 9.1 becomes effective, the Issuer or, at the
direction of the Issuer, the Trustee shall mail to the Noteholders a notice
briefly describing such amendment. Any failure of the Issuer or the Trustee to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amendment.

       

      After an
amendment under this Section 9.1 becomes effective, it shall bind every
Noteholder, whether or not notation thereof is made on any Note held by such
Noteholder.

       

      Section
9.2                                Modification Without Consent
of Noteholder.  The Trustee may agree, without the consent of
any Noteholder:

       

      (a)           to
evidence the succession of a successor to the Trustee, the removal of the
Trustee or the appointment of any separate or additional trustee or trustees and
to define the rights, powers, duties and obligations conferred upon any such
separate trustee or trustees or co-trustees;

       

      (b)           to
correct, confirm or amplify the description of any property at any time subject
to the lien of this Indenture or to convey, transfer, assign, mortgage or pledge
any property to or with the Trustee;

       

      (c)           to
cure any ambiguity in, correct or supplement any defective or inconsistent
provision of this Indenture, the Notes, the Purchase and Sale Agreement, the
Bill of Sale, the Servicing Agreement, the MedPro Guarantee or the Pledge and
Security Agreement, in any manner that will not, in the judgment of the Trustee,
adversely affect the interests of the Noteholders;

       

      (d)           to
grant or confer upon the Trustee for the benefit of the Noteholders any
additional rights, remedies, powers, authority or security which may be lawfully
granted or conferred and which are not contrary or inconsistent with this
Indenture;

      (e)           to
add to the covenants or agreements to be observed by the Issuer, which are not
contrary to this Indenture, or to add Events of Default for the benefit of the
Noteholders;

       

      (f)           to
comply with the requirements of the SEC or any regulatory body or any applicable
law, rules or regulations; or

       

      (g)           to
effect any indenture supplemental hereto or any other amendment, modification,
supplement, waiver or consent with respect to this Indenture, the Notes, the
Purchase and Sale Agreement, the Bill of Sale, the Servicing Agreement, the
MedPro Guarantee or the Pledge and Security Agreement; provided, that such
indenture supplemental hereto, amendment, modification, supplement, waiver or
consent will not adversely affect the interests of the Noteholders as confirmed
in an Officer’s Certificate of the Issuer and the Trustee.

       

      After an
amendment under this Section 9.2 becomes effective, the Issuer or, at the
direction of the Issuer, the Trustee shall mail to the Noteholders a notice
briefly describing such amendment and a copy of such amendment. Any failure of
the Issuer or the Trustee to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such
amendment.

       

      After an
amendment under this Section 9.2 becomes effective, it shall bind every
Noteholder, whether or not notation thereof is made on any Note held by such
Noteholder.

       

      Section
9.3                                Execution of Amendments by
Trustee.  In executing, or accepting the additional trusts
created by, any amendment or modification to this Indenture permitted by this
Article IX or the modifications thereby of the trusts created by this Indenture,
the Trustee shall be entitled to receive, and shall be fully protected in
relying upon, an Officer’s Certificate and an Opinion of Counsel stating that
the execution of such amendment is authorized or permitted by this Indenture.
The Trustee may, but shall not be obligated to, enter into any such amendment
which affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise.

       

      Section
9.4                                Conformity with Trust
Indenture Act.  Every indenture supplemental hereto pursuant to
this Article IX shall conform to the requirements of the Trust Indenture Act as

      Section
10.1                                Discharge of
Indenture.

       

      (a)           When
(i) all outstanding Secured Obligations have been satisfied and the Issuer
delivers to the Trustee all Outstanding Notes (other than Notes replaced
pursuant to Section 2.8) for cancellation or (ii) all Outstanding Notes have
become due and payable, whether at maturity or otherwise, and the Issuer
irrevocably deposits in the Collection Account funds sufficient to pay all
remaining Trustee Expenses and Other Expenses accrued and payable through such
date and to pay all principal and interest on outstanding Notes at maturity or
earlier acceleration (including any Incremental Interest Payment), and if in
either case the Issuer pays all other sums payable hereunder by the Issuer, then
this Indenture shall, subject to Section 10.1(b), cease to be of further effect
and the security interest granted to the Trustee hereunder in the Collateral and
the Indenture Estate shall terminate. The Trustee shall acknowledge satisfaction
and discharge of this Indenture, and file all UCC termination statements and
similar documents prepared by the Issuer, on demand of the Issuer accompanied by
an Officer’s Certificate and an Opinion of Counsel, at the cost and expense of
the Issuer, to the effect that any conditions precedent to a discharge of this
Indenture have been met.

      (b)           Notwithstanding
Section 10.1(a), the Issuer’s obligations in Section 8.1 and the Trustee’s
obligations in Section 11.13 shall survive the satisfaction and discharge of
this Indenture.

      MISCELLANEOUS

       

      Section
11.1                                Right of Trustee to
Perform.  If the Issuer for any reason fails to observe or
punctually to perform any of its obligations to the Trustee, whether under this
Indenture, under any of the other Transaction Documents or otherwise, the
Trustee shall have the power (but shall have no obligation), on behalf of or in
the name of the Issuer or otherwise, to perform such obligations or cause
performance of such obligations and to take any steps which the Trustee may, in
its absolute discretion, consider appropriate with a view to remedying, or
mitigating the consequences of, such failure by the Issuer, in which case the
reasonable expenses of the Trustee, including the fees and expenses of its
counsel, incurred in connection therewith shall be payable by the Issuer under
Section 8.1; provided, that no
exercise or failure to exercise this power by the Trustee shall in any way
prejudice the Trustee’s other rights under this Indenture or any of the other
Transaction Documents.

       

      Section
11.2                                Waiver.  Any
waiver by any party of any provision of this Indenture or any right, remedy or
option hereunder shall only prevent and estop such party from thereafter
enforcing such provision, right, remedy or option if such waiver is given in
writing and only as to the specific instance and for the specific purpose for
which such waiver was given. The failure or refusal of any party hereto to
insist in any one or more instances, or in a course of dealing, upon the strict
performance of any of the terms or provisions of this Indenture by any party
hereto or the partial exercise of any right, remedy or option hereunder shall
not be construed as a waiver or relinquishment of any such term or provision,
but the same shall continue in full force and effect. No failure on the part of
the Trustee to exercise, and no delay on its part in exercising, any right or
remedy under this Indenture will operate as a waiver thereof, nor will any
single or partial exercise of any right or remedy preclude any other or further
exercise thereof or the exercise of any other right or remedy. The rights and
remedies provided in this Indenture are cumulative and not exclusive of any
rights or remedies provided by law.

       

      Section
11.3                                Severability.  In
the event that any provision of this Indenture or the application thereof to any
party hereto or to any circumstance or in any jurisdiction governing this
Indenture shall, to any extent, be invalid or unenforceable under any applicable
statute, regulation or rule of law, then such provision shall be deemed
inoperative to the extent that it is invalid or unenforceable, and the remainder
of this Indenture, and the application of any such invalid or unenforceable
provision to the parties, jurisdictions or circumstances other than to whom or
to which it is held invalid or unenforceable, shall not be affected thereby nor
shall the same affect the validity or enforceability of this Indenture. The
parties hereto further agree that the holding by any court of competent
jurisdiction that any remedy pursued by the Trustee hereunder is unavailable or
unenforceable shall not affect in any way the ability of the Trustee to pursue
any other remedy available to it.

      Section
11.4                                Restrictions on Exercise of
Certain Rights.  The Trustee may sue for recovery or take any
other steps for the purpose of recovering any of the obligations hereunder or
any other debts or liabilities whatsoever owing to it by the Issuer. Each of the
Noteholders shall at all times be deemed to have agreed by virtue of the
acceptance of the Notes that only the Trustee, except as provided in Section
4.4, may take any steps for the purpose of procuring the appointment of an
administrative receiver, examiner, receiver or similar officer or the making of
an administration order or for instituting any bankruptcy, reorganization,
arrangement, insolvency, winding-up, liquidation, composition, examination or
any like proceedings under Applicable Law.

WITH SUCH LAWS.

       

      Section
11.10                                Jurisdiction.

       

      (a)           Each
of the parties hereto agrees that the U.S. federal and State of New York courts
located in the Borough of Manhattan, The City of New York shall have
jurisdiction to hear and determine any suit, action or proceeding, and to settle
any disputes, which may arise out of or in connection with this Indenture and,
for such purposes, submits to the jurisdiction of such courts. Each of the
parties hereto waives any objection which it might now or hereafter have to the
U.S. federal or State of New York courts located in the Borough of Manhattan,
The City of New York being nominated as the forum to hear and determine any
suit, action or proceeding, and to settle any disputes, which may arise out of
or in connection with this Indenture and agrees not to claim that any such court
is not a convenient or appropriate forum. Each of the parties hereto has
irrevocably designated, appointed and empowered the respective Persons named in
Exhibit C as
its designee, appointee and agent to receive, accept and acknowledge for and on
its behalf, and its properties, assets and revenues, service of any and all
legal process, summons, notices and documents that may be served in any suit,
action or proceeding brought against such party in any United States or state
court arising out of or relating to this Indenture or the Notes. If for any
reason any such designee, appointee and agent hereunder shall cease to be
available to act as such, such party agrees to designate a new designee,
appointee and agent in the Borough of Manhattan, The City of New York on the
terms and for the purposes of this Section 11.9 satisfactory to such other
party. Each party further hereby irrevocably consents and agrees to the service
of any and all legal process, summons, notices and documents in any suit, action
or proceeding against such party by serving a copy thereof upon the relevant
agent for service of process referred to in this Section 11.9 (whether or not
the appointment of such agent shall for any reason prove to be ineffective or
such agent shall accept or acknowledge such service) or by mailing copies
thereof by registered or certified mail, postage prepaid, to such party at its
address specified in or designated pursuant to this Indenture. Each party agrees
that the failure of any such designee, appointee and agent to give any notice of
such service to it shall not impair or affect in any way the validity of such
service or any judgment rendered in any action or proceeding based thereon.
Nothing herein shall in any way be deemed to limit the ability of the Issuer or
the Trustee and the Noteholders, as the case may be, to serve any such legal
process, summons, notices and documents in any other manner permitted by
applicable law or to obtain jurisdiction over such party or bring suits, actions
or proceedings against such party in such other jurisdictions, and in such
manner, as may be permitted by applicable law.

      (b)           The
submission to the jurisdiction of the courts referred to in Section 11.9(a)
shall not (and shall not be construed so as to) limit the right of the Trustee
to take proceedings against the Issuer in any other court of competent
jurisdiction, nor shall the taking of proceedings in any one or more
jurisdictions preclude the taking of proceedings in any other jurisdiction,
whether concurrently or not.

       

      (c)           Each
of the parties hereto hereby consents generally in respect of any legal action
or proceeding arising out of or in connection with this Indenture to the giving
of any relief or the issue of any process in connection with such action or
proceeding, including the making, enforcement or execution against any property
whatsoever (irrespective of its use or intended use) of any order or judgment
which may be made or given in such action or proceeding.

       

      (d)           If,
for the purpose of obtaining a judgment or order in any court, it is necessary
to convert a sum due hereunder to any Noteholder from U.S. dollars into another
currency, the Issuer has agreed, and each Noteholder by holding a Note will be
deemed to have agreed, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which, in accordance with normal
banking procedures, such Noteholder could purchase U.S. dollars with such other
currency in the Borough of Manhattan, The City of New York on the Business Day
preceding the day on which final judgment is given.

       

      (e)           The
obligation of the Issuer in respect of any sum payable by it to a Noteholder
shall, notwithstanding any judgment or order in a currency other than U.S.
dollars (the “Judgment
Currency”), be discharged only to the extent that, on the Business Day
following receipt by such Noteholder of such security of any sum adjudged to be
so due in the Judgment Currency, such Noteholder may in accordance with normal
banking procedures purchase U.S. dollars with the Judgment
Currency.  If the amount of U.S. dollars so purchased is less than the
sum originally due to such Noteholder in the Judgment Currency (determined in
the manner set forth in Section 12.9(c)), the Issuer agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify such Noteholder
against such loss, and, if the amount of the U.S. dollars so purchased exceeds
the sum originally due to such Noteholder, such Noteholder agrees to remit to
the Issuer such excess, provided that such Noteholder shall have no obligation
to remit any such excess as long as the Issuer shall have failed to pay such
Noteholder any obligations due and payable under the Notes of such Noteholder,
in which case such excess may be applied to such obligations of the Issuer under
such Notes in accordance with the terms thereof.  The foregoing
indemnity shall constitute a separate and independent obligation of the Issuer
and shall continue in full force and effect notwithstanding any such judgment or
order as aforesaid.

OF THE PARTIES HERETO IRREVOCABLY WAIVES ALL RIGHT OF TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN CONNECTION WITH THIS
INDENTURE OR ANY MATTER ARISING HEREUNDER.

each such counterpart shall be considered an original and all such counterparts
shall constitute one and the same instrument.

       

      Section
11.12                                Table of Contents and

      Section
11.13                                Trust Indenture
Act.  This Indenture shall not be qualified under the Trust

      Section
11.14                                Confidential Information of
Greiner.  The Trustee, in its individual capacity and as
Trustee, agrees and acknowledges that all Confidential Information provided to
the Trustee by MedPro is considered to be proprietary and confidential
information of Greiner.  The Trustee agrees to take all reasonable
precautions necessary to keep the Confidential Information confidential, which
precautions shall be no less stringent than those which the Trustee employs to
protect its own confidential information. The Trustee shall not disclose to any
third party other than as set forth herein, and shall not use for any purpose
other than the exercise of the Trustee’s rights and the performance of its
obligations under this Indenture, any Confidential Information without the prior
written consent of Greiner, as the case may be. In addition, the Trustee agrees
to be bound by the provisions of Article 8 of the Manufacturing Agreement (as
set out in Exhibit
J) to the extent it receives Confidential Information pursuant to Section
5.3 of this
Indenture or Section 4.1 of the Servicing Agreement. The Trustee shall limit
access to Confidential information received hereunder to (a) its directors,
officers, managers and employees and (b) its legal advisors, to each of whom
disclosure of Confidential Information is necessary for the purposes described
above; provided, however, that in each
case, such party has expressly agreed to maintain such Confidential Information
in confidence under terms and conditions substantially identical to the terms of
this Section 11.13.

       

      The
Trustee agrees that Greiner has no responsibility whatsoever for any reliance on
Confidential Information by the Trustee or by any Person to whom the
Confidential Information is disclosed in connection with this Indenture, whether
related to the purposes described above or otherwise. Without limiting the
generality of the foregoing, the Trustee agrees that Greiner makes no
representation or warranty whatsoever to it with respect to Confidential
Information or its suitability for such purposes.  The Trustee further
agrees that it shall not acquire any rights against Greiner or any employee,
officer, director, manager, representative or agent of Greiner (together with
Greiner, “Confidential
Parties”) as a result of the disclosure of Confidential Information to
the Trustee or to any Noteholder or Beneficial Holder and that no Confidential
Party has any duty, responsibility, liability or obligation to any Person as a
result of any such disclosure.

      In the
event the Trustee is required to disclose any Confidential Information received
hereunder in order to comply with any laws, regulations or court orders, it may
disclose such Confidential Information only to the extent necessary for such
compliance; provided, however, that it
shall give Greiner and the Issuer reasonable advance written notice of any such
court proceeding in which such disclosure may be required pursuant to a court
order so as to afford Greiner a full and fair opportunity to oppose the issuance
of such order and to appeal therefrom and shall cooperate reasonably with
Greiner in opposing such order and in securing confidential treatment of any
Confidential Information to be disclosed and/or obtaining a protective order
narrowing the scope of such disclosure.

       

      The
Trustee agrees that Greiner is an express third-party beneficiary of the
provisions of this Section 11.13.

       

      Each of
the Calculation Agent and the Registrar agrees to be bound by this Section 11.13
to the same extent as the Trustee.

      MEDPRO
INVESTMENTS, LLC, a limited liability company organized under the laws of the
State of Delaware (herein referred to as the “Issuer”), for value
received, hereby promises to pay to CEDE & CO., or registered assigns, the
principal amount of ______________________________ Dollars
($______________________) on or before October 30, 2016 (the “Final Maturity Date”)
and to pay interest quarterly in arrears on the Outstanding Principal Balance
hereof at a rate per annum equal to 14% (the “Stated Rate of
Interest”), from the date hereof until the Outstanding Principal Balance
hereof is paid or duly provided for; provided, that the
Stated Rate of Interest may be increased by seventy-five hundredths of a percent
(0.75%) during certain periods of time as further described in the Indenture (as
defined below); provided, further, that after
the occurrence and during the continuance of a Default or an Event of Default,
the Outstanding Principal Balance hereof shall accrue interest at the Default
Rate.

       

      Interest
on this Note will be payable quarterly in arrears on January 30, April 30, July
30 and October 30 (each a “Payment Date”) of
each year, commencing October 30, 2010.  Interest on this Note will be
calculated on the basis of a 360 day year consisting of twelve thirty day months
(except that the initial interest accrual period will commence on the Closing
Date and end on, but exclude, the first Payment Date).  If the
Available Collections Amount on any Payment Date on or prior to January 30, 2013
are insufficient to pay all of the interest required to be paid in cash on such
Payment Date, then any funds in the Reserve Account and, to the extent set forth
in the Indenture (as defined below), the Capital Account will be used to pay
such shortfall.  Interest not paid on any Payment Date shall be
payable in full not later than the immediately succeeding Payment Date, together
with Additional Interest on the amount of unpaid interest from the Payment Date
on which such interest was due until the date on which such interest is paid,
compounded quarterly, until paid. If such shortfall (and interest thereon) is
not paid in full by the succeeding Payment Date, then an Event of Default under
the Indenture will occur.

       

      This Note
also evidences the right to receive the Incremental Interest Payment as further
provided under the Indenture.

      This Note
is a duly authorized issue of Notes of the Issuer, designated as its “MedPro
Investments Senior Secured 14% Notes Due 2016”, issued under the Indenture dated
as of September 1, 2010 (as amended, restated, supplemented or otherwise
modified from time to time in accordance with the terms thereof, the “Indenture”), between
the Issuer and U.S. Bank National Association, as trustee (including any
successor appointed in accordance with the terms of the Indenture, the “Trustee”). All
capitalized terms used in this Note and not defined herein shall have the
respective meanings assigned to such terms in the Indenture. Reference is made
to the Indenture and all indentures supplemental thereto for a statement of the
respective rights and obligations thereunder of the Issuer, the Trustee and the
Noteholders. This Note is subject to all terms of the Indenture.

       

      The
Issuer will pay the Outstanding Principal Balance of this Note on or prior to
the Final Maturity Date on the Payment Dates and in the amounts specified in the
Indenture, as further provided in Section 3.7 of the Indenture, subject to the
availability of the Available Collections Amount therefor after making payments
entitled to priority under Section 3.7 of the Indenture.

       

      The
Interest Amount payable on each Payment Date shall be paid as set forth in
Section 3.7 of the Indenture.

       

      The
maturity of this Note is subject to acceleration upon the occurrence and during
the continuance of the Events of Default specified in the
Indenture.

       

      Without
the consent of Noteholders of 100% of the Outstanding Principal Balance of the
Notes, the Issuer shall not be permitted to optionally redeem, repurchase,
defease, acquire, retire, refinance or otherwise pay or repay the Notes prior to
the Final Maturity Date.

       

      Any
amount of interest on this Note that is not paid when due shall, to the fullest
extent permitted by applicable law, bear interest (“Additional Interest”)
at an interest rate per annum equal to the Stated Rate of Interest from the date
when due until such amount is paid or duly provided for, compounded quarterly
and payable on the next succeeding Payment Date, subject to the availability of
the Available Collections Amount therefor after making payments entitled to
priority under Section 3.7 of the Indenture.

       

      This Note
is and will be secured by the Collateral pledged as security therefor as
provided in the Indenture and the other Transaction Documents.  This
Note is guaranteed by MedPro pursuant to the MedPro Guarantee.

       

      Subject
to and in accordance with the terms of the Indenture, there will be distributed
quarterly from the Collection Account on each Payment Date commencing on October
30, 2010, to the Person in whose name this Note is registered at the close of
business on the Record Date with respect to such Payment Date, in the manner
specified in Section 3.7 of the Indenture, such Person’s pro rata share (based
on the aggregate percentage of the Outstanding Principal Balance of the Notes
held by such Person) of the aggregate amount distributable to all Noteholders on
such Payment Date.

      All
amounts payable in respect of this Note shall be payable in U.S. dollars in the
manner provided in the Indenture to the Noteholder hereof on the Record Date
relating to such payment. The final payment with respect to this Note, however,
shall be made only upon presentation and surrender of this Note by the
Noteholder or its agent at the Corporate Trust Office or agency of the Trustee
or Paying Agent. At such time, if any, as this Note is issued in the form of one
or more Definitive Notes, payments on a Payment Date shall be made by check
mailed to each Noteholder of such a Definitive Note on the applicable Record
Date at its address appearing on the Register maintained with respect to the
Notes. Alternatively, upon application in writing to the Trustee, not later than
the applicable Record Date, by a Noteholder, any such payments shall be made by
wire transfer to an account designated by such Noteholder at a financial
institution in New York City. The final payment with respect to any such
Definitive Note, however, shall be made only upon presentation and surrender of
such Definitive Note by the Noteholder or its agent at the Corporate Trust
Office or agency of the Trustee or Paying Agent. Notwithstanding the foregoing,
payments in respect of this Note issued in the form of a Global Note (including
principal and interest) shall be made by wire transfer of immediately available
funds to the account specified by DTC. Any reduction in the Outstanding
Principal Balance of this Note (or any one or more predecessor Notes) effected
by any payments made on any Payment Date shall be binding upon all future
Noteholders of this Note and of any Note issued upon the registration of
transfer of, in exchange or in lieu of this Note, whether or not noted
hereon.

       

      The
Noteholder of this Note agrees, by acceptance hereof, to pay over to the Trustee
any money (including principal and interest) paid to it in respect of this Note
in the event that the Trustee, acting in good faith, determines subsequently
that such monies were not paid in accordance with the priority of payment
provisions of the Indenture or as a result of any other mistake of fact or law
on the part of the Trustee in making such payment.

       

      This Note
is issuable only in registered form. A Noteholder or Beneficial Holder may
transfer this Note or a Beneficial Interest herein only by delivery of a written
application to the Registrar stating the name of the proposed transferee, a
Confidentiality Agreement duly executed and delivered to the Registrar by such
transferee and otherwise complying with the terms of the Indenture. No such
transfer shall be effected until, and such transferee shall succeed to the
rights of a Noteholder only upon, final acceptance and registration of the
transfer by the Registrar in the Register. When this Note is presented to the
Registrar with a request to register the transfer or to exchange it for an equal
principal amount of Notes of other authorized denominations, the Registrar shall
register the transfer or make the exchange as requested if its requirements for
such transactions are met (including, in the case of a transfer, that such Note
is duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Trustee and Registrar duly executed by the Noteholder
thereof or by an attorney who is authorized in writing to act on behalf of the
Noteholder and that the transferee has executed and delivered to the Registrar a
Confidentiality Agreement). No service charge shall be made for any registration
of transfer or exchange of this Note, but the party requesting such new Note or
Notes may be required to pay a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith. This Note may not
be transferred to any Person engaged in the business of developing,
manufacturing or marketing biotechnology, diagnostics, pharmaceutical, medicine,
and in vitro diagnostics  products, or any Affiliate of such a
Person.

      Prior to
the registration of transfer of this Note, the Issuer and the Trustee may deem
and treat the Person in whose name this Note (as of the day of determination or
as of such other date as may be specified in the Indenture) is registered as the
absolute owner and Noteholder hereof for the purpose of receiving payment of all
amounts payable with respect to this Note and for all other purposes, and
neither the Issuer nor the Trustee shall be affected by notice to the
contrary.

       

      The
Indenture permits the amendment or modification of the Indenture and the Notes
by the Issuer with the consent of the Noteholders of a majority of the
Outstanding Principal Balance of the Notes on the date of any vote or act of
such Noteholders. However, no amendment or modification of the Indenture or the
Notes may, without the consent of Noteholders of 100% of the Outstanding
Principal Balance of the Notes affected thereby, (1) reduce the percentage of
Noteholders required to take or approve any action under the Indenture, (ii)
reduce the amount or change the time of payment of any amount owing or payable
with respect to the Notes or change the rate of interest or change the manner of
calculation of interest payable with respect to the Notes, (iii) alter or modify
the provisions with respect to the Collateral for the Notes or the manner of
payment or the order of priorities in which payments or distributions under the
Indenture will be made as between the Noteholders and the Issuer or as among the
Noteholders or (iv) consent to any assignment of the Issuer’s rights to a party
other than the Trustee for the benefit of the Noteholders. Any such amendment or
modification shall be binding on every Noteholder hereof, whether or not
notation thereof is made upon this Note.

       

      The
Indenture also contains provisions permitting the Noteholders of a majority of
the Outstanding Principal Balance of the Notes, on behalf of all of the
Noteholders, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver shall be conclusive and binding upon all present and
future Noteholders and of any Note issued upon the registration of transfer of,
in exchange or in lieu of this Note, whether or not notation of such consent or
waiver is made upon this Note.

       

      The
Issuer is permitted by the Indenture, under certain circumstances, to merge or
consolidate, subject to the rights of the Trustee and the Noteholders under the
Indenture.

       

      The Notes
are issuable only in registered form in denominations as provided in the
Indenture, subject to certain limitations therein set forth.

       

      THIS NOTE
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL SUBSTANTIVE
LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO THE RULES THEREOF RELATING TO
CONFLICTS OF LAW OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE
STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES HEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

benefit under the Indenture, or be valid or obligatory for any
purpose.

      RESALE CONFIDENTIALITY
AGREEMENT

       

      In
connection with our interest in the potential purchase of MedPro Investments
Senior Secured 14% Notes Due 2016 issued by you (the “Notes”), we have
requested that you furnish us with the Private Placement Memorandum, dated
August 31, 2010, relating to the Notes (the “Private Placement
Memorandum”).  In addition to receiving the Private Placement
Memorandum, we may also have conversations with you or your representatives or
receive additional information from you or your representatives about the Notes
or your business.  As used in this letter agreement, the term “Information” means
(i) the Private Placement Memorandum, (ii) any additional information we receive
from you or your representatives about the Notes or your business, and (iii) any
internal reports or analyses we prepare that incorporate or utilize any
information described in clauses (i) or (ii) (in the case of clauses (ii) and
(iii), whether oral or written, whether in tangible or electronic form, or
otherwise).  The term Information also includes all confidential and
proprietary information of Greiner Bio-One GmbH (“Greiner”) related to
that certain Medical Supply Manufacturing Agreement between MedPro Safety
Products, Inc. (“MedPro”) and Greiner,
dated as of July 14, 2010, as amended (the “Manufacturing
Agreement”), including but not limited to product sales and royalties
paid under the Manufacturing Agreement, the business and operations of Greiner,
Greiner finances, and such other information relating thereto as may be provided
by you, MedPro or Greiner (“Greiner
Information”).  The term Information will not, however, include
information which (i) is or becomes publicly available other than as a result of
a disclosure by us, (ii) was already known to us, as evidenced by our
contemporaneous written records at the time of disclosure by you, or (iii) was
disclosed to us by a third party who, to the best of our knowledge, had no
obligation to you, MedPro or Greiner not to disclose sued information to
others.

       

      We
represent and warrant that we are not in the business of developing,
manufacturing or marketing pharmaceutical or diagnostic products.  We
represent and warrant that we are not a controlled affiliate of an entity which
is in the business of developing, manufacturing or marketing pharmaceutical or
diagnostic products.

       

      As a
condition to receiving the Information, we hereby agree that:

       

      
        
          
          

        

        
          B-1

          
            

          

        

        
          
          

        

      

       

      
        	
                1.

              	
                In
      consideration of your making the Information available to us, and Greiner
      agreeing to permit such action by you in respect of Information which may
      be restricted from disclosure under the Manufacturing Agreement, we (i)
      will take all reasonable precautions to keep the Information confidential,
      which precautions will be no less stringent than those we employ to
      protect our own confidential information, and will not (except as required
      by applicable law, regulation or legal process, and only after compliance
      with paragraph 2 below or as contemplated by paragraph 5 or 6 below),
      without your prior written consent, disclose any Information in any manner
      whatsoever and (ii) will not use any Information for any purpose other
      than in connection with our considering or making an investment in the
      Notes.

              

      

       

      
        	
                2.

              	
                In
      the event that we are requested pursuant to or required by applicable law,
      regulation or legal process to disclose any of the Information (excluding
      any disclosure to a Governmental Authority which regulates us), we will
      notify Greiner and you promptly (unless such notice is not permitted by
      applicable law or regulation) so that (i) Greiner or you are afforded a
      full and fair opportunity to seek, at Greiner’s or your expense, a
      protective order or other appropriate remedy, and appeal from any denial
      thereof, and we agree to cooperate reasonably with Greiner and you in
      seeking such order and in securing confidential treatment for any
      Information to be disclosed or (ii) in Greiner’s or your sole discretion,
      as applicable, Greiner or you may waive compliance with the terms of this
      letter agreement.  In the event that no such protective order or
      other remedy is obtained, or that Greiner or you do not waive compliance
      with the terms of this letter agreement, we will furnish only that portion
      of the Information which we are advised by counsel is legally required and
      will exercise all reasonable efforts to obtain reliable assurance that
      confidential treatment will be accorded the Information.  We
      represent and warrant to you that we are not aware of any applicable law,
      regulation or legal process that we reasonably foresee will require the
      disclosure of Information, other than to you as permitted hereunder and
      pursuant to the terms hereof or to Governmental Authorities that regulate
      us.

              

      

       

      
        	
                3.

              	
                If
      we decide not to purchase the Notes, we will promptly inform you of that
      decision and, in such case, and at any time upon your request, we will (i)
      promptly deliver to you all copies of the Information in our possession
      (except as described in the following clause) and (ii) promptly destroy
      all copies of any written Information (whether in tangible or electronic
      form, or otherwise) that we have created, including, without limitation,
      any notes we have taken on any discussions with you, provided, in each
      ease, that we may retain one copy of the Information, subject to the
      provisions of this letter agreement, if necessary to comply with
      applicable law or regulation.  Any oral Information will
      continue to be subject to the terms of this letter
    agreement.

              

      

       

      
        	
                4.

              	
                We
      acknowledge that the Private Placement Memorandum is dated August 31,
      2010, and that you have not updated, and have no obligation to update, the
      Private Placement Memorandum in any respect for events, developments or
      circumstances.  No express or implied representation or warranty
      as to the accuracy or completeness of any Information or as to the
      suitability of the Information for evaluating a possible investment in the
      Notes is made by you or any representative acting for you or as a broker
      or market maker for the Notes, and we agree that none of such persons will
      have any liability relating thereto or for any errors therein or omissions
      therefrom.  We agree that we acquire no rights against Greiner
      or any employee, officer, director, representative or agent of Greiner
      (together with Greiner, the “Greiner
      Representatives”) as a result of the disclosure of Information to
      us or our Representatives and that no Greiner Representative has any duty,
      responsibility, liability or obligation to us as a result of such
      disclosure.

                5.

              	
                We
      may disclose Information to our advisors, attorneys and affiliates who
      have a need to know the Information in connection with our investment
      decision (our “Representatives”),
      but only if we
      deliver to each such Representative a copy of this letter agreement
      executed by us and if such Representative expressly agrees in writing to
      maintain the Information in confidence under terms and conditions
      substantially identical to this letter agreement.  We will be
      responsible for any breach of this letter agreement by any of our
      Representatives.

              

      

       

      
        	
                6.

              	
                If
      we propose to transfer, sell, or otherwise dispose of any Notes at any
      time, we agree to (i) abide by the transfer restrictions described in the
      Private Placement Memorandum, (ii) inform any proposed transferee of the
      Notes of such transfer restrictions, including the requirement that such
      proposed transferee enter into a confidentiality agreement with you and
      (iii) not furnish any Information to such proposed transferee, or
      transfer, sell or dispose of any Note to such proposed transferee, without
      receiving evidence that such proposed transferee has entered into a
      confidentiality agreement with you.

              

      

       

      
        	
                7.

              	
                We
      acknowledge that remedies at law may be inadequate to protect you against
      any actual or threatened breach of this letter agreement by us, and,
      without prejudice to any other rights and remedies otherwise available to
      you, we agree to the granting of injunctive relief in your favor without
      proof of actual damages.

              

      

       

      
        	
                8.

              	
                We
      acknowledge that we are aware of the restrictions imposed by the United
      States securities laws on the purchase or sale of securities of an issuer
      or an affiliate or controlling person of the issuer (such as, in our case,
      MedPro) by any person who has received material, non–public information
      from the issuer or an affiliate or controlling person of the issuer, and
      on the communication of such information to any other person when it is
      reasonably foreseeable that such other person is likely to purchase or
      sell such securities in reliance upon such
  information.

              

      

       

      
        	
                9.

              	
                We
      agree that (i) neither party to the Manufacturing Agreement expressly or
      implicitly waives any of its rights, whether contractual or otherwise,
      that such party has or may have under or in connection with the
      Manufacturing Agreement or otherwise with respect to us and (ii) no
      failure or delay by you in exercising any right, power or privilege
      hereunder will operate as a waiver thereof, nor will any single or partial
      exercise thereof preclude any other or further exercise thereof or the
      exercise of any right, power or privilege
  hereunder.

              

      

       

      
        	
                10.

              	
                We
      agree that this letter agreement is for the benefit of, and may be
      enforced by, Greiner or you, acting either independently or
      together.

                11.

      letter agreement will be governed by and construed in accordance with the
      laws of the State of New York applicable to contracts between residents of
      that State and executed in and to be performed in that

      conditions hereof will be effective, unless approved in writing by each of
      Greiner, you and us.

              

      

       

      
        	
                13.

      letter agreement will, subject to the proviso below, terminate eighteen
      (18) months alter the earlier of the date we sell the Notes or the date

      herein concerning maintaining the confidentiality of Information that is
      Greiner Information (and not otherwise excluded from restriction by the
      last sentence of the first paragraph of this letter), this letter
      agreement will terminate five years after the expiration or termination of

      Ladies
and Gentlemen:

       

      In
connection with our proposed sale of U.S.$_________ aggregate principal amount
of MedPro Investments Senior Secured 14% Notes Due 2016 of the Issuer (the
“Notes”), we confirm that such sale has been effected pursuant to and in
accordance with Regulation S under the U.S. Securities Act of 1933, as amended
(“Regulation
S”) and, accordingly, we represent that:

       

      1.           the
offer of the Notes was not made to a person in the U.S.;

       

      2.           at
the time the buy order was originated, the transferee was an institution outside
the U.S. or we and any person acting on our behalf reasonably believed that the
transferee was an institution outside the U.S.;

       

      3.           no
directed selling efforts have been made by us in the U.S. in contravention of
the requirements of Rule 903(b) or Rule 904(b) of Regulation 5, as
applicable;

       

      4.           the
transaction is not part of a plan or scheme to evade the registration
requirements of the U.S. Securities Act of 1933; and

       

      5.           the
transferee has entered into the confidentiality agreement required in connection
with the purchase of the Notes.

      Ladies
and Gentlemen:

       

      In
connection with our proposed purchase of Notes (the “Notes”) of MedPro
Investments, LLC (the “Issuer”), we confirm
that:

       

      1.           We
have duly executed and delivered to the Registrar (as defined in that certain
Indenture dated as of September 1, 2010 (the “Indenture”) between
the Issuer and U.S. Bank National Association, as trustee, as amended, restated,
supplemented or otherwise modified from time to time in accordance with the
terms thereof) a Resale Confidentiality Agreement and have subsequently received
a copy of the Private Placement Memorandum dated August 31, 2010 (the “Private Placement
Memorandum”) relating to the Notes and such other information as we deem
necessary in order to make our investment decision. We acknowledge that we have
read and agreed to the matters stated in the section entitled “Transfer
Restrictions” of such Private Placement Memorandum and the restrictions on
duplication and circulation of such Private Placement Memorandum.

       

      2.           We
understand that any subsequent transfer of the Notes is subject to certain
restrictions and conditions set forth in the Private Placement Memorandum under
“Transfer Restrictions” and the undersigned agrees to be bound by, and not to
resell, pledge or otherwise transfer the Notes except in compliance with, such
restrictions and conditions and the U.S. Securities Act of 1933, as amended (the
“Securities
Act”).

       

      3.           We
understand that the offer and sale of the Notes have not been registered under
the Securities Act, that the Notes will only be in the form of definitive
physical certificates and that the Notes may not be offered or sold except as
permitted in the following sentence. We agree, on our own behalf and on behalf
of any accounts for which we are acting as hereinafter stated, that, if we
should sell any Notes in the future, we will do so only (1) (A) to the Issuer or
any subsidiary thereof, (B) in accordance with Rule 144A under the Securities
Act to a qualified institutional buyer (as defined therein), (C) to an
institutional accredited investor (as defined in Rule 501 (a)(1), (2), (3) or
(7) of Regulation D under the Securities Act) that, prior to such transfer,
furnishes to the Trustee (as defined in the Indenture) a signed letter
containing certain representations and agreements relating to the restrictions
on transfer of the Notes (the form of which letter can be obtained from the
Trustee) and an opinion of counsel acceptable to the Issuer that such transfer
is in compliance with the Securities Act, (D) to an institution in an offshore
transaction in compliance with Rule 904 of Regulation S under the Securities
Act, (E) pursuant to the exemption from registration provided by Rule 144 under
the Securities Act (if available) or pursuant to another available exemption
from registration under the Securities Act, as applicable or (F) pursuant to an
effective registration statement under the Securities Act, and we further agree
to provide to any person or entity purchasing any of the Notes from us a notice
advising such purchaser that resales of the Notes are restricted as stated
herein and (2) in each case, in accordance with any applicable securities laws
of any state in the U.S. or any other applicable jurisdiction and in accordance
with the legend to be set forth in the Notes, which will reflect the substance
of this paragraph.

      4.           We
understand that, on any proposed resale of any Notes, we will be required to
furnish to the Issuer and the Trustee such certifications, legal opinions and
other information as the Issuer and the Trustee may reasonably require to
confirm that the proposed sale complies with the foregoing restrictions. We
further understand that a resale confidentiality agreement is required under the
Indenture to be executed and delivered by any proposed transferee to whom we
wish to sell any Notes.

       

      5.           We
are an institutional accredited investor and have such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of our investment in the Notes, and we and any accounts for which we are
acting are able to bear the economic risks of our or their
investment.

       

      6.           We
are acquiring the Notes purchased by us for our own account or for one or more
accounts (each of which is an institutional accredited investor) as to each of
which we exercise sole investment discretion.

       

      7.           We
are not acquiring the Notes with a view to distribution thereof or with any
present intention of offering or selling the Notes, except as permitted above,
provided that the disposition of our property and property of any accounts for
which we are acting as fiduciary shall remain at all times within our
control.

Issuer and the Trustee are entitled to rely upon this letter and are irrevocably
authorized to produce this letter or a copy hereof to any interested party in
any administrative or legal proceeding or official inquiry with respect to the

      SUPPLEMENTAL CONFIDENTIALITY
AGREEMENT

       

      In
connection with our interest in obtaining information provided by Greiner

Inc., as amended, restated, supplemented or otherwise modified from time to time
(the “Manufacturing

and conditions of Article 8 of the Manufacturing Agreement in the same manner as
if we were a party thereto (which Article 8 is attached as Exhibit A
hereto).

       

      This
Supplemental Confidentiality Agreement shall in no manner affect our obligations
under the Confidentiality Agreement dated ___________, 20_ between you and us
(the “Initial

      As a
condition to receiving the Confidential Information, we hereby agree as
follows:

       

      1.           We
acknowledge that remedies at law may be inadequate to protect you or the parties
to the Manufacturing Agreement (the “Parties”) against any
actual or threatened breach of this Supplemental Confidentiality Agreement by
us, and, without prejudice to any other rights and remedies otherwise available
to you and the Parties, we agree to the granting of injunctive relief in your
and the Parties’ favor without proof of actual damages.

       

      2.           We
acknowledge that we are aware of the restrictions imposed by the United States
securities laws on the purchase or sale of securities of an issuer or an
affiliate or controlling person of the issuer by any person who has received
material, non-public information from the issuer or an affiliate or controlling
person of the issuer or from a person owing a duty to any of the foregoing, and
on the communication of such information to any other person when it is
reasonably foreseeable that such other person is likely to purchase or sell such
securities in reliance upon such information.

       

      3.           We
agree that no failure or delay by you or the Parties in exercising any right,
power or privilege hereunder or under the Manufacturing Agreement will operate
as a waiver thereof, nor will any single or partial exercise thereof preclude
any other or further exercise thereof or the exercise of any right, power or
privilege hereunder or under the Manufacturing Agreement.

Supplemental Confidentiality Agreement will be governed by and construed in
accordance with the laws of the State of New York applicable to contracts
between residents of the State of New York and executed in and to be performed
in the State of New York.

       

      5.           This
Supplemental Confidentiality Agreement will terminate five years after the
termination of the Manufacturing Agreement.

       

      6.           Except
for the Initial Confidentiality Agreement, this Supplemental Confidentiality
Agreement contains the entire agreement between you and us concerning the
Confidential Information, and no modification of this Supplemental
Confidentiality Agreement or waiver of the terms and conditions hereof will be
binding upon you or us, unless approved in writing by each of you and
us.

      EXHIBIT
A

       

      The
following text of Article 8 of the Manufacturing Agreement is excerpted from the
redacted version of the Manufacturing Agreement:

       

      ARTICLE 8
- CONFIDENTIALITY

       

      8.1           Confidential
Information. MedPro and GBO acknowledge that in the course of
performing their duties hereunder, they will be necessarily gaining access to
each other’s secret and proprietary information, including, without limitation
the existence and terms of this Agreement (the “Confidential
Information”).

       

      8.2           Disclosure. Nothing
contained herein shall in any way restrict or impair any party’s right to use,
disclose or otherwise deal with any information or data which:

       

      (a)           At
the time of the disclosure is generally available to the public or thereafter
becomes generally available to the public, by publication or otherwise, through
no act of the disclosing party, its employees, consultants or advisors or of any
person or entity bound by an obligation of confidentiality to the non-disclosing
party;

       

      (b)           The
disclosing party can show was in its possession prior to the time of the
disclosure to it and was not acquired from the non-disclosing party or any other
source which is bound by an obligation of confidentiality to the non-disclosing
party;

       

      (c)           The
disclosing party can show was received by it as a matter of lawful right after
the time of disclosure from a third party who did not acquire it from the
non-disclosing party under an obligation of confidence and that without breach
of any obligation, the disclosing party is free to disclose it to others;
or

       

      (d)           Is
required to be disclosed pursuant to court order, federal, state, or foreign
government regulation or requirement of a federal, state, or foreign
governmental authority.

       

      8.3           Nondisclosure. Both
MedPro and GBO shall maintain in confidence any Confidential Information which
is disclosed directly or indirectly to it by the other party, and shall not make
any use of such Confidential Information other than performing services
hereunder or disclose such information to any third party without the other
party’s express prior written consent. MedPro will notify GBO and submit to GBO
articles any informational releases that it is aware of or responsible for that
reference the Products and GBO. This notification shall be sent to GBO three (3)
days prior to public release for GBO comment. MedPro shall endeavor to eliminate
any information that GBO believes will be commercially or competitively have a
negative market impact. MedPro’s and GBO’s obligations under this Article 8
shall survive for a period of twenty-four (24) months following the end of the
Term, whether by expiration or termination.

       

      8.4           Disclosure to Governmental
Authorities. Nothing contained herein shall in any way restrict or impair
any party’s ability to disclose Confidential Information to any federal, state,
or foreign governmental authority, if it is required to do so; provided,
however, that:  (a) the party that is required to disclose the
Confidential Information shall provide the other party with prior written notice
of any such required disclosure, sufficient to allow the other party to petition
the governmental authority, prior to such disclosure, for confidential
protection of the Confidential Information; and (b) the party required to
disclosure the Confidential Information shall cooperate with the other party (as
reasonably required) in obtaining such protection from the governmental
authority.

       

      
        
          
          

        

        
          J-3

          
            

          

        

        
          
          

        

      

       

      8.5           Injunctive
Relief. Each of MedPro and GBO acknowledges that the other party has
no adequate remedy at law and would be irreparably harmed if it breaches or
threatens to breach the provisions of this Article 8, and therefore, both
parties agree that the injured party shall be entitled to injunctive relief to
prevent any breach or threatened breach of those provisions and to specific

      This
CONTINUING UNCONDITIONAL GUARANTEE (this “Guarantee”), dated as
of September 1, 2010, is made by MEDPRO SAFETY PRODUCTS, INC., a Nevada
corporation (“Guarantor”), to U.S.
BANK NATIONAL ASSOCIATION, as trustee under the Indenture hereinafter described
(together with its successor and assigns, the “Trustee”), for the
benefit of the Trustee and the Noteholders.

       

    

    W I T N E S S E T H
:

     

    WHEREAS,
MedPro Investments, LLC, a Delaware limited liability company (“Issuer”), is entering
into that certain Indenture, dated as of the date hereof (as the same may be
amended, modified, supplemented or restated from time to time, the “Indenture”), with
Trustee pursuant to which Issuer is concurrently issuing its MedPro Investments
Senior Secured 14% Notes due 2016 (the “Notes”) (all
capitalized terms used herein shall have the same meaning as ascribed to them in
the Indenture unless otherwise expressly stated); and

     

    WHEREAS,
the purchasers of the Notes (“Initial Purchasers”)
have required that Guarantor execute and deliver this Guarantee to Trustee, for
the benefit of the Trustee, Initial Purchasers and any Person to whom the Notes
are transferred in accordance with the Indenture (collectively, “Noteholders”), as a
condition precedent to the purchase of the Notes; and

     

    WHEREAS,
Guarantor is the sole member of Issuer and will directly or indirectly receive
certain benefits from the credit accommodations hereinabove described and is
therefore willing to guaranty the prompt payment and performance of the
Obligations (as such term is hereinafter defined) of Issuer, on the terms set
forth in this Guarantee.

     

    NOW,
THEREFORE, for value received and in consideration of the purchase of the Notes
by Initial Purchasers, the undersigned unconditionally guarantees (i) the
full and prompt payment when due, whether at maturity or earlier, by reason of
acceleration or otherwise, and at all times thereafter, of all of the
indebtedness and obligations of every kind and nature of Issuer under the Notes
owing to the Noteholders, including, without limitation, with respect to the
payment of principal, interest, and collection costs owing under the Notes and
under the Indenture with the other Transaction Documents to which the Issuer is
party (all such indebtedness and obligations being hereinafter referred to as
the “Obligations”).  Guarantor
further agrees to pay all out-of-pocket costs and expenses, including, without
limitation, all court costs, costs of settlement and reasonable attorneys’ and
paralegals’ fees paid or incurred by Trustee or any Noteholder in collecting or
enforcing, or the prosecution or preservation of any rights under, all or any
part of the Obligations from, or in prosecuting or otherwise enforcing any
action against, Guarantor, including under this Guarantee and the other
Transaction Documents (together with the Obligations, the “Guaranteed
Obligations”).  The term “Guaranteed  Obligations” is
used herein in its most comprehensive sense and includes any and all Obligations
of the Issuer in respect of notes, borrowings, loans, debts, interest, fees,
costs, expenses (including, without limitation, legal fees and expenses of
counsel and allocated costs of internal counsel), indemnities and liabilities of
whatsoever nature now or hereafter made, incurred or created, whether absolute
or contingent, liquidated or unliquidated, whether due or not due, and however
arising under or in connection with Notes, Indenture and the other Transaction
Documents.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    All
amounts payable by Guarantor under this Guarantee shall be payable upon demand
by Trustee or any Noteholder and shall be made in lawful money of the United
States, in immediately available funds.

     

    Any
interest on any portion of the Guaranteed Obligations that accrues after the
commencement of any proceeding, voluntary or involuntary, involving the
bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement
of Issuer (or, if interest on any portion of the Guaranteed Obligations ceases
to accrue by operation of law by reason of the commencement of said proceeding,
such interest as would have accrued on such portion of the Guaranteed
Obligations if said proceeding had not been commenced) shall be included in the
Guaranteed Obligations because it is the intention of Guarantor, the Trustee and
the Noteholders that the Guaranteed Obligations should be determined without
regard to any rule of law or order that may relieve Guarantor or Issuer of any
portion of such Guaranteed Obligations.

     

    In the
event that all or any portion of the Guaranteed Obligations is paid by Issuer,
the obligations of Guarantor hereunder shall continue and remain in full force
and effect or be reinstated, as the case may be, in the event that all or any
part of such payment(s) is rescinded or recovered directly or indirectly from
Trustee or any other Noteholder as a preference, fraudulent transfer or
otherwise, and any such payments that are so rescinded or recovered shall
constitute Guaranteed Obligations.

     

    Upon the
failure of Issuer to pay any of the Guaranteed Obligations when and as the same
shall become due, Guarantor will upon demand pay, or cause to be paid, in cash,
to Trustee for the ratable benefit of Noteholders, an amount equal to the
aggregate of the unpaid Guaranteed Obligations.

     

    SECTION
1. No
Fraudulent Conveyance.  Notwithstanding any provision of this
Guarantee to the contrary, it is intended that this Guarantee, and any
Encumbrances granted by Guarantor to secure this Guarantee, do not constitute a
“Fraudulent Conveyance” (as defined below).  Consequently, Guarantor
agrees that if this Guarantee, or any Encumbrances securing this Guarantee,
would, but for the application of this sentence, constitute a Fraudulent
Conveyance, this Guarantee and each such Encumbrance shall be valid and
enforceable only to the maximum extent that would not cause this Guarantee or
such Encumbrance to constitute a Fraudulent Conveyance, and this Guarantee or
the Transaction Documents providing for such Encumbrance shall automatically be
deemed to have been amended accordingly at all relevant times.  For
purposes hereof, “Fraudulent
Conveyance” means a fraudulent conveyance under Section 548 of the
Bankruptcy Code (as hereinafter defined) or a fraudulent conveyance or
fraudulent transfer under the provisions of any applicable fraudulent conveyance
or fraudulent transfer law or similar law of any state, nation or other
governmental unit, as in effect from time to time.

     

    SECTION
2. Unconditional
Guaranty.  Guarantor hereby agrees that its obligations under
this Guarantee shall be unconditional, irrespective of any condition or
circumstance, including, without limitation, (i) the validity or
enforceability of the Obligations or any part thereof, or of the Notes or any
other document evidencing all or any part of the Obligations, (ii) the
absence of any attempt to collect from Issuer or any other guarantor or Person
of all or any part of the Obligations or other action to enforce the same,
(iii) the waiver, modification, extension, amendment or consent by Trustee
or Noteholders with respect to any provision of any instrument evidencing the
Obligations, or any part thereof, or any other agreement heretofore, now or
hereafter executed by Issuer or any other guarantor or Person of all or any part
of the Obligations, and delivered to Trustee, (iv) failure by Trustee to
take any steps to perfect and maintain its security interest in, or to preserve
its rights to, any security or collateral for the Obligations or any guarantee
or other agreement, (v) the existence or nonexistence of any defenses which may
be available to Issuer or any other guarantor or Person of all or any part of
the Obligations, (vi) the institution of any proceeding under Chapter 11 of
Title 11 of the United States Code (11 U.S.C. § 101 et seq.), as amended (the
“Bankruptcy
Code”), or any similar proceeding, by or against any of Issuer or any
other guarantor or Person or Trustee’s election in any such proceeding of the
application of Section 1111(b)(2) of the Bankruptcy Code, (vii) any
borrowing or grant of a security interest by Issuer, as debtor-in-possession,
under Section 364 of the Bankruptcy Code (or use of cash collateral under
Section 363 of the Bankruptcy Code), (viii) the disallowance, under Section
502 of the Bankruptcy Code, of all or any portion of Trustee’s or any
Noteholder’s claim(s) for repayment of the Obligations, (ix) any assignment
or other transfer of the Issuer’s interest or any assumption of the Issuer’s
obligations under the Notes, the Indenture or any
Transaction  Document or (x) any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a
guarantor.

    SECTION
3. Waiver.  Guarantor
hereby waives diligence, presentment, demand of payment, filing of claims with a
court in the event of receivership or bankruptcy of Issuer or other guarantors
or Persons, protest or notice with respect to the Obligations and all demands
whatsoever, and covenants that this Guarantee will not be discharged, except by
complete and indefeasible payment and performance of the Guaranteed
Obligations.  Guarantor further waives notice of (i) acceptance
of this Guarantee, (ii) the existence or incurring from time to time of any
Obligations guaranteed hereunder, (iii) the existence of any Default or Event of
Default, the making of demand, nonpayment, or the taking of any action by
Trustee or any Noteholder, under the Indenture or any of the other Transaction
Documents, (iv) the benefit of any statute of limitations and (v) default and
demand hereunder.  Upon the occurrence and during the continuance of
any Event of Default, Trustee may, at its sole election, proceed directly and at
once, without notice, against Guarantor to collect and recover the full amount
or any portion of the Obligations, without first proceeding against Issuer or
any other guarantor or Person, or against any security or collateral for the
Obligations.  Guarantor’s obligations hereunder shall not be subject
to any reduction, limitation, impairment or termination for any reason,
including, without limitation, any claim of waiver, release, surrender,
attention or compromise and shall not be subject to, and the Guarantor hereby
irrevocably waives, any defense or set-off, counterclaim, recoupment, or
termination whatsoever by reason of the invalidity, illegality or
unenforceability of any of Guarantor’s obligations hereunder or
otherwise.  Guarantor agrees that this Guarantee constitutes a
guarantee of payment when due and not of collection.

     

    SECTION
4. Authorization.  Each
of the Trustee and each Noteholder is hereby authorized, without notice or
demand and without affecting the liability of Guarantor hereunder, at any time
and from time to time to (i) renew, extend, accelerate or otherwise change
the time for payment of, or other terms relating to, the Obligations or
otherwise modify, amend or change the terms of the Notes or other agreement,
document or instrument now or hereafter executed by Issuer or any other
guarantor or Person; (ii) accept partial payments on the Obligations;
(iii) take and hold security or collateral for the payment of the
Obligations guaranteed hereby, or for the payment of this Guarantee, or for the
payment of any other guaranties of the Obligations, and exchange, enforce, waive
and release any such security or collateral; (iv) apply such security or
collateral and direct the order or manner of sale or other disposition thereof
as in its discretion it may determine; and (v) settle, release, compromise,
collect or otherwise liquidate the Obligations and any security or collateral
therefor in any manner, without affecting or impairing the obligations of
Guarantor hereunder.  The time and manner of application of any
payments or credits, whether received from Issuer or any other source, shall be
made by Trustee in accordance with the Indenture.  All such payments
and credits may be applied, reversed and reapplied, in whole or in part, to any
of the Obligations as Trustee shall determine in its discretion without
affecting the validity or enforceability of this Guarantee.

    SECTION
5. Guarantor’s
Responsibility.  Guarantor hereby assumes responsibility for
keeping itself informed of the financial condition of Issuer and any and all
endorsers and/or other guarantors of any instrument or document evidencing all
or any part of the Obligations and of all other circumstances bearing upon the
risk of nonpayment of the Obligations or any part thereof, and Guarantor hereby
agrees that neither Trustee nor any Noteholder shall have any duty to advise
Guarantor of information known to Trustee or such Noteholder regarding such
condition or any such circumstances or to undertake any
investigation.  If Trustee or any Noteholder, in its discretion,
undertakes at any time or from time to time to provide any such information to
Guarantor, neither Trustee nor such Noteholder shall be under any obligation to
update any such information or to provide any such information to Guarantor on
any subsequent occasion.  Guarantor further acknowledges that
Guarantor has examined or had the opportunity to examine the Indenture and the
other Transaction Documents, and waives any defense which may exist resulting
from Guarantor’s failure to receive or examine at any time the Indenture or the
other Transaction Documents.

     

    SECTION
6. Consent.  Guarantor
consents and agrees that neither Trustee nor any Noteholder shall be under any
obligation to marshal any assets in favor of Guarantor or against or in payment
of any or all of the Obligations. Guarantor further agrees that, to the extent
that Issuer, Guarantor or any other Person makes a payment or payments to
Trustee or a Noteholder, or Trustee or a Noteholder receives any proceeds of
collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid or otherwise repaid to Issuer, its estates, trustees,
receivers or any other Person, including, without limitation, Guarantor,
including under any bankruptcy law, state or federal law, common law or
equitable theory, then to the extent of such payment or repayment, the
Obligations or the part thereof which has been paid, reduced or satisfied by
such amount, and Guarantor’s obligations hereunder with respect to such portion
of the Obligations, shall be reinstated and continued in full force and effect
as of the date such initial payment, reduction or satisfaction
occurred.

     

    SECTION
7. Binding
on Assigns.  This Guarantee shall be binding upon Guarantor and
upon its successors (including, without limitation, any receiver, trustee or
debtor-in-possession of or for Guarantor) and assigns of Guarantor, and shall
inure to the benefit of Trustee and its successors and assigns; provided, however, that
Guarantor’s obligations hereunder may not be delegated or assigned without
Trustee’s prior written consent.

    SECTION
8. Representations and
Warranties.  Guarantor represents and warrants (which
representations and warranties shall survive the execution and delivery hereof)
to Trustee and Noteholders that:

     

    (a)           Guarantor
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 Guarantee and
the other Transaction Documents to which it is party.  Guarantor 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.  Guarantor has the full corporate power and authority to own the
property it purports to own, to carry on its business as presently conducted and
as proposed to be conducted and to execute, deliver and perform this Guarantee
and the other Transaction Documents to which it is party.

     

    (b)           The
consummation of the transactions contemplated hereby has been duly and validly
authorized by Guarantor.  Guarantor has full corporate power to
execute and deliver this Guarantee and the other Transaction Document to which
it is party and to perform its obligations hereunder and
thereunder.  This Guarantee and each of the other Transaction
Documents to which it is party has been duly authorized, executed and delivered
by Guarantor.  This Guarantee and each of the other Transaction
Documents to which it is party constitutes a legal, valid and binding obligation
of Guarantor enforceable against Guarantor 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 Guarantor to make this Guarantee and the other
Transaction Documents to which it is party valid and binding upon
Guarantor.

     

    (c)           No
consent of any other party (including, without limitation, shareholders,
directors or creditors of Guarantor) and no government approval is required
which has not been obtained (i) for the execution, delivery and performance by
Guarantor of this Guarantee and each other Transaction Document to which it is a
party, or (ii) or the exercise by Trustee or any Noteholder of the rights
provided for in this Guarantee or the other Transaction Documents.

     

    (d)           The
execution, delivery and performance of this Guarantee and the other Transaction
Documents to which it is party and the consummation of the transactions
contemplated by this Guarantee and such other Transaction Documents do not (i)
violate the provisions of the articles of incorporation or bylaws (or
equivalents thereof) of Guarantor, (ii) violate the provisions of any law
(including, without limitation, any usury law), regulation or order of any
government authority applicable to Guarantor, (iii) result in a breach of,
or constitute a default under, any material agreement relating to the management
or affairs of Guarantor, or any indenture or loan agreement or any other
agreement, lease or instrument to which Guarantor is a party or by which
Guarantor 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 under, or require any consent which has not been
obtained under, any indenture (including the Indenture) or loan agreement or any
other agreement, instrument or document or the provisions of any order, writ,
judgment, injunction, decree, determination or award of any government
authority, binding upon Guarantor or any of its properties.

     

    
      
         

      

      
        -5-

        
          

        

      

      
         

      

       

    

    (e)           There
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 Guarantor or, to the best knowledge of Guarantor, threatened
against Guarantor which questions the validity or legality of or seeks damages
in connection with this Guarantee or the other Transaction Documents to which
Guarantor is party or which seeks to prevent the consummation of any of the
transactions contemplated by this Guarantee or any other Transaction
Document.

     

    (f)           It
is in Guarantor’s direct interest to assist Issuer in procuring credit because
Guarantor has a direct investment in or business relationship with
Issuer.

     

    SECTION
9. Continuation.  This
Guarantee shall continue in full force and effect (and may not be revoked or
terminated) until such time as Trustee has, in writing, notified Guarantor that
all of the Obligations have been indefeasibly paid and satisfied in full and the
Indenture has been terminated.

     

    SECTION
10. Subrogation.  Guarantor
shall not at any time exercise any and all rights of any nature of guarantor to
subrogation, contribution, reimbursement or indemnity and any right of Guarantor
to recourse to any assets or property of, or payment from, Issuer or any other
guarantor or Person of all or any part of the Obligations as a result of any
payments made or to be made hereunder for any reason, unless and until all of
the Obligations have been indefeasibly paid and satisfied in
full.  Any payments received by Guarantor in violation of this Section
shall be held in trust for and immediately remitted to Trustee.

     

    SECTION
11. Subordination.  The
payment of any and all of indebtedness, liabilities and obligations of Issuer to
Guarantor of every kind or nature, whether joint or several, due or to become
due, absolute or contingent, now existing or hereafter arising, and whether
principal, interest, fees, costs, expenses or otherwise (collectively, the
“Subordinated
Debt”), is expressly subordinated to the Obligations.  So long
as any Obligations remain outstanding and the Indenture has not been terminated,
no payment of any kind (by voluntary payment, prepayment, acceleration, setoff
or otherwise) of any portion of the Subordinated Debt may be made by Issuer or
received or accepted by Guarantor at any time.  Until such time as the
Obligations have been indefeasibly paid and satisfied in full and the Indenture
has been terminated, Guarantor will not (i) obtain any Encumbrance on any
property of Issuer to secure the Subordinated Debt, or (ii) make demand for
payment of the Subordinated Debt or commence any lawsuit, action or proceeding
of any kind against Issuer to recover all or any part of the Subordinated
Debt.  Any payments received by Guarantor in violation of this Section
shall be held in trust for and immediately remitted to Trustee.

    SECTION
12. GOVERNING
LAW.  THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO THE RULES THEREOF RELATING TO CONFLICTS OF LAW OTHER THAN SECTION
5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, AND THE
OBLIGATIONS, RIGHTS AND REMEDIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE
WITH SUCH LAWS.

     

    SECTION
13. CONSENT TO JURISDICTION;
SERVICE OF PROCESS; JURY TRIAL WAIVER.  ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS GUARANTEE OR ANY DOCUMENT RELATED HERETO MAY BE
BROUGHT IN THE COURTS OF THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK OR OF
THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND
GUARANTOR HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY
AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID
COURTS. GUARANTOR AND THE TRUSTEE ON BEHALF OF ITSELF AND THE NOTEHOLDERS HEREBY
IRREVOCABLY WAIVE TRIAL BY JURY, AND GUARANTOR HEREBY IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE
OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR
HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH
RESPECTIVE JURISDICTIONS. GUARANTOR IRREVOCABLY CONSENTS TO THE SERVICE OF
PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY
THE SENDING OF COPIES THEREOF BY FEDERAL EXPRESS OR OTHER OVERNIGHT COURIER
COMPANY, TO GUARANTOR AT GUARANTOR’S ADDRESS IN ACCORDANCE WITH SECTION [12.5]
OF THE INDENTURE, SUCH SERVICE TO BECOME EFFECTIVE FOUR DAYS AFTER DELIVERY TO
SUCH COURIER COMPANY. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE TRUSTEE
OR ANY NOTEHOLDER TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO
COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST GUARANTOR IN ANY OTHER
JURISDICTION.

     

    SECTION
14. Entire
Agreement; Severability.  This Guarantee represents the entire
understanding and agreement between Guarantor, on the one hand, and Trustee and
Noteholders, on the other hand, with respect to the subject matter contained
herein, and there are no other existing agreements or understandings, whether
oral or written, between or among such parties as to such subject
matter.  Wherever possible, each provision of this Guarantee shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Guarantee shall be prohibited by or invalid under
applicable law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Guarantee.

     

    SECTION
15. Cumulative Remedies;
Amendments.  All rights and remedies hereunder and under the
Indenture and the other Transaction Documents are cumulative and not
alternative, and Trustee and each Noteholder may proceed in any order from time
to time against Issuer, Guarantor or any other guarantor of all or any part of
the Obligations and their respective assets.  Neither Trustee nor any
Noteholder shall have any obligation to proceed at any time or in any manner
against, or exhaust any or all of Trustee’s or any Noteholder’s rights against,
Issuer or any other guarantor or other Person of all or any part of the
Obligations prior to proceeding against Guarantor hereunder.  No
failure or delay on the part of Trustee or any Noteholder in the exercise of any
power, right or privilege shall impair such power, right or privilege or be
construed to be a waiver of any default or acquiescence therein, nor shall any
single or partial exercise of any such power, right or privilege preclude other
or further exercise thereof or of any other right, power or
privilege.  No amendment, modification or waiver of any provision of
this Guarantee, or consent to any departure by Guarantor therefrom, shall be
effective unless the same shall be in writing and signed by Trustee and
Guarantor.  Each amendment, modification or waiver shall be effective
only in the specific instance and for the specific purpose for which it was
given.

    SECTION
16. Counterparts;
Effectiveness.  This Guarantee and any amendments, waivers,
consents or supplements may be executed in counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument.  This
Guarantee shall become effective upon the execution and delivery of a
counterpart hereof by each of the parties hereto.

     

    SECTION
17. Covenants. Guarantor
agrees that, so long as any part of the Guaranteed Obligations shall remain
unpaid, Guarantor will perform or observe, and cause its Subsidiaries to perform
or observe, all of the terms, covenants and agreements that the Transaction
Documents state that the Guarantor is to perform or observe or that Issuer is to
cause Guarantor to perform or observe.

     

    SECTION
18. Trustee.

     

    (a)           Trustee
has been appointed to act as Trustee hereunder by the
Noteholders.  Trustee shall have the right hereunder, to make demands,
to give notices, to exercise or refrain from exercising any rights, and to take
or refrain from taking any action, solely in accordance with this Guarantee and
the Indenture; provided that Trustee shall exercise, or refrain from exercising,
