      in the corrected form and, irrespective of the date or dates of the actual
      execution and/or delivery thereof, such substitute document or instrument shall
      be deemed to have been executed and/or delivered as of the date or dates
      required with respect to the document or instrument for which it is substituted.

      corrective document or instrument indicates that action has been taken by or
      at
      the request of the Company which could not have been taken had the original
      document or instrument not contained such error or omission, the action so
      taken
      shall not be invalidated or otherwise rendered ineffective but shall be and
      remain in full force and effect, except to the extent that such action was
      a
      result of willful misconduct or bad faith. Without limiting the generality
      of
      the foregoing, any Securities issued under the authority of such defective

      Act,

      called the “Company,”
which
      term includes any successor corporation under the Indenture hereinafter referred
      to), for value received, hereby promises to pay to CEDE & Co., or registered
      assigns, the principal amount of [_________] Dollars (such Initial Principal
      Amount, as it may from time to time be adjusted by endorsement on Schedule
      A
      hereto, is hereinafter referred to as the “Principal
      Amount”)
      on May

      Interest Payment Date to which interest has been paid or duly provided for,
      semi-annually on May 15 and November 15 in each year, commencing November 15,
      2007, at the rate of 5.95% per annum, until the Principal Amount hereof is
      paid
      or made available for payment; provided that any Principal Amount and premium,
      and any such installment of interest, which is overdue shall bear interest
      at
      the rate of 5.95% per annum (or, if lower, the maximum rate legally enforceable)
      from the dates such amounts are due until they are paid or made available for
      payment; provided, further, that if a Registration Default (as defined in the

      will accrue on this Security at a rate of 0.5% per annum from and including
      the
      date on which any such Registration Default shall occur, until but excluding
      the
      date on which all Registration Defaults have been cured. The interest so
      payable, and punctually paid or duly provided for, on any Interest Payment
      Date

      preceding such Interest Payment Date. Any such interest not so punctually paid
      or duly provided for will forthwith cease to be payable to the Person in whose
      name this Security (or one or more Predecessor Securities) is registered on

      (or one or more Predecessor Securities) is registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest to be fixed
      by the Trustee, notice whereof shall be given to Holders of Securities of this
      series not less than 10 days prior to such Special Record Date, or be paid
      at
      any time in any other lawful manner not inconsistent with the requirements
      of
      any securities exchange on which the Securities of this series may be listed,
      and upon such notice as may be required by such exchange, all as more fully
      provided in said Indenture.

     

    Payment
      of the principal of (and premium, if any) and interest, if any, on this Security

      in such coin or currency of the United States as at the time of payment is
      legal
      tender for the payment of public and private debts, provided,
      however,
      that,
      payment of interest may be made by check mailed to the address of the Person
      entitled thereto as such address shall appear in the Security Register. Payment
      of interest, if any, in respect of this Security may also be made, in the case
      of a Holder of at least U.S. $1,000,000 aggregate principal amount of
      Securities, by wire transfer to a U.S. Dollar account maintained by the Holder
      with a bank in the United States; provided that such Holder elects payment
      by
      wire transfer by giving written notice to the Trustee or Paying Agent to such
      effect designating such account no later than 15 days immediately preceding
      the

      between the Company and The Bank of New York Trust Company, N.A., as trustee
      (the “Trustee”),

      as
      amended and supplemented by
      the
      Fifth Supplemental Indenture, dated as of May 11, 2007 (together with the Base
      Indenture, the “Indenture”),
      between the Company and the Trustee, to which Indenture and all indentures
      supplemental thereto reference is hereby made for a statement of the respective
      rights, limitations of rights, duties and immunities thereunder of the Company,
      the Trustee and the Holders of the Securities and of the terms upon which the
      Securities are, and are to be, authenticated and delivered. Terms defined in
      the
      Indenture which are not defined herein are used with the meanings assigned
      to
      them in the Indenture. This Security is one of the series designated on the
      face
      hereof.

     

    2.     OPTIONAL
      REDEMPTION

     

    The
      Securities of this series are subject to redemption upon not less than 30 or
      more than 60 days’ notice to the Holders of such Securities as provided in the
      Indenture, at any time, as a whole or in part, at the election of the Company,
      at a redemption price equal to the greater of: (i) 100% of the principal amount
      of the Securities of this series being redeemed or (ii) the sum of the present
      values of the remaining scheduled payments of principal of and interest on
      the
      Securities of this series being redeemed discounted to the Redemption Date
      on a
      semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
      at
      a discount rate equal to the Treasury Yield plus 25 basis points, plus, for
      (i)
      or (ii) above, whichever is applicable, accrued interest on the Securities
      of
      this series to the Redemption Date.

     

    “Treasury
      Yield”
means,
      with respect to any Redemption Date, the rate per annum equal to the semiannual
      equivalent yield to maturity of the Comparable Treasury Issue, assuming a price
      for the Comparable Treasury Issue (expressed as a percentage of its principal
      amount) equal to the Comparable Treasury Price for such Redemption
      Date.

     

    “Comparable
      Treasury Issue”
means
      the United States Treasury security selected by an Independent Investment Banker
      as having a maturity comparable to the remaining term of the Securities of
      this
      series to be redeemed that would be utilized, at the time of selection and
      in
      accordance with customary financial practice, in pricing new issues of corporate
      debt securities of comparable maturity to the remaining term of the Securities
      of this series.

     

    “Comparable
      Treasury Price”
means,
      with respect to any Redemption Date, (i) the average of the bid and asked prices
      for the Comparable Treasury Issue (expressed in each case as a percentage of
      its
      principal amount) on the third Business Day in New York City preceding such
      Redemption Date, as set forth in the daily statistical release (or any successor
      release) published by the Federal Reserve Bank of New York and designated
“Composite 3:30 p.m. Quotations for U.S. Government Securities” or (ii) if such
      release (or any successor release) is not published or does not contain such
      prices on such Business Day, the Reference Treasury Dealer Quotation for such
      Redemption Date.

     

    
      
        
        

      

      
        Exhibit
          A-7

        
          

        

      

      
        
        

      

    

     

    “Independent
      Investment Banker”
means
      an investment banking institution of international standing appointed by the
      Company.

     

    “Reference
      Treasury Dealer”
means
      a
      primary U.S. government securities dealer in New York City appointed by the
      Company.

     

    “Reference
      Treasury Dealer Quotation”
means,
      with respect to the Reference Treasury Dealer and any Redemption Date, the
      average, as determined by the Company, of the bid and asked prices for the
      Comparable Treasury Issue (expressed in each case as a percentage of its
      principal amount and quoted in writing to the Company by such Reference Treasury
      Dealer at 5:00 p.m. on the third Business Day in New York City preceding such
      Redemption Date).

     

    Notice
      of
      redemption pursuant to this paragraph 2 shall be given as provided for in the
      Indenture not less than 30 days nor more than 60 days prior to the Redemption
      Date.

     

    If
      fewer
      than all the Securities of this series are to be redeemed, selection of
      Securities of this series for redemption will be made by the Trustee on a pro
      rata basis.

     

    Unless
      the Company defaults in payment of the Redemption Price, from and after the
      Redemption Date, the Securities of this series or portions thereof called for
      redemption will cease to bear interest, and the Holders thereof will have no
      right in respect of such Securities of this series except the right to receive
      the Redemption Price thereof.

     

    In
      the
      event of redemption of this Security in part only, the Trustee will reduce
      the
      Principal Amount hereof by endorsement on Schedule A hereto such that the
      Principal Amount shown on Schedule A after such endorsement will reflect only
      the unredeemed portion hereof.

     

    3.     DEFEASANCE

     

    The
      Indenture contains provisions for defeasance of (a) the entire indebtedness
      of
      this Security and (b) certain restrictive covenants upon compliance by the
      Company with certain conditions set forth therein.

     

    4.     DEFAULTS
      AND REMEDIES

     

    If
      an
      Event of Default with respect to Securities of this series shall occur and
      be
      continuing, the principal of the Securities of this series may be declared
      due
      and payable in the manner and with the effect provided in the Indenture. At
      any
      time after such declaration of acceleration with respect to Securities of this
      series has been made, but before a judgment or decree for payment of money
      has
      been obtained by the Trustee as provided in the Indenture, if all Events of
      Default with respect to Securities of this series have been cured or waived
      (other than the non-payment of principal of the Securities of this series which
      has become due solely by reason of such declaration of acceleration) then and
      in
      every such case, the Holders of a majority in aggregate principal amount of
      the
      Outstanding securities of such series may, by written notice to the Company
      and
      to the Trustee, rescind and annul such declaration and its consequences on
      behalf of all of the Holders, but no such rescission or annulment shall extend
      to or affect any subsequent default or impair any right consequent
      thereon.

     

    
      
        
        

      

      
        Exhibit
          A-8

        
          

        

      

      
        
        

      

    

     

    As
      provided in and subject to the provisions of the Indenture, the Holder of this
      Security shall not have the right to institute any proceeding, judicial or
      otherwise, with respect to the Indenture, or for the appointment of a receiver
      or trustee or for any other remedy thereunder, unless (a) such Holder shall
      have
      previously given the Trustee written notice of a continuing Event of Default
      with respect to the Securities, (b) the Holders of not less than 33% or a
      majority, as applicable, in principal amount of the Securities at the time
      Outstanding under the Indenture shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default as Trustee, (c)
      such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
      against the costs, expenses and liabilities to be incurred in compliance with
      such request, (d) the Trustee shall not have received from the Holders of a
      majority in principal amount of Securities at the time Outstanding under the
      Indenture a direction inconsistent with such request and (e) the Trustee for
      90
      days after its receipt of such notice and offer of indemnity from the Holder,
      and request from the Holders, shall have failed to institute any such
      proceeding. The foregoing shall not apply to certain suits described in the
      Indenture, including any suit instituted by the Holder of this Security for
      the
      enforcement of any payment of principal hereof or any premium or interest hereon
      on or after the respective due dates expressed herein.

     

    5.     AMENDMENT
      AND WAIVER

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the Indenture or any supplemental indenture
      or
      the rights and obligations of the Company and rights of the Holders of the
      Securities of any series at any time by the Company and the Trustee with the
      consent of the Holders of a majority in aggregate principal amount of the
      Securities at the time Outstanding of each series to be affected. The Indenture
      also contains provisions permitting the Holders of specified percentages in
      principal amount of the Securities of each series at the time Outstanding,
      on
      behalf of the Holders of all Securities of such series, to waive compliance
      by
      the Company with certain provisions of the Indenture and certain past defaults
      under the Indenture and their consequences. Any such consent or waiver by the
      Holder of this Security shall be conclusive and binding upon such Holder and
      upon all future Holders of this Security and of any Security issued upon the
      registration of transfer hereof or in exchange herefor or in lieu hereof,
      whether or not notation of such consent or waiver is made upon this
      Security.

     

    No
      reference herein to the Indenture and no provision of this Security or of the
      Indenture shall alter or impair the obligation of the Company, which is absolute
      and unconditional, to pay the principal of (and premium, if any) and interest,
      if any, on this Security at the times, place and rate, and in the coin or
      currency, herein prescribed.

    6.     TRANSFER
      AND EXCHANGE; DENOMINATIONS

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,
      the transfer of a Security of the series of which this Security is a part is
      registrable in the Security Register, upon surrender of this Security for
      registration of transfer at the office or agency of the Company in any place
      where the principal of (and premium, if any) and interest, if any, on this
      Security are payable, duly endorsed by, or accompanied by a written instrument
      of transfer in form satisfactory to the Company and the Security Registrar
      duly
      executed by, the Holder hereof or his attorney duly authorized in writing,
      and
      thereupon one or more new Securities of this series and of like tenor, of
      authorized denominations and for the same aggregate principal amount, will
      be
      issued to the designated transferee or transferees.

     

    The
      Securities of the series of which this Security is a part are issuable only
      in
      registered form, without coupons, in denominations of $2,000 and any integral
      multiple of $1,000 in excess thereof.

     

    No
      service charge shall be made for any such registration of transfer or exchange,
      but the Company may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    Prior
      to
      due presentment of this Security for registration of transfer, the Company,
      the
      Trustee and any agent of the Company or the Trustee may treat the Person in
      whose name this Security is registered as the owner hereof for all purposes,
      whether or not this Security be overdue, and neither the Company, the Trustee
      nor any such agent shall be affected by notice to the contrary.

     

    7.     SUCCESSOR
      OBLIGORS

     

    When
      a
      successor assumes all the obligations of its predecessor under the Securities
      of
      this series and the Indenture in accordance with the terms of the Indenture,
      the
      predecessor will be released from those obligations.

     

    8.     TRUSTEE
      DEALINGS WITH THE COMPANY

     

    The
      Trustee under the Indenture, in its individual or any other capacity, may become
      the owner or pledgee of Securities of this series and may otherwise deal with
      the Company, its Subsidiaries or their respective Affiliates as if it were
      not
      the Trustee.

     

    9.     NO
      RECOURSE AGAINST OTHERS

     

    No
      stockholder, director, officer, employee, incorporator or Affiliate of the
      Company shall have any liability for any obligation of the Company under the
      Securities of this series or the Indenture or for any claim based on, in respect
      of or by reason of, such obligations or their creation. Each Holder of the
      Securities of this series by accepting a Security of this series waives and
      releases all such liability. The waiver and release are part of the
      consideration for the issuance of the Securities of this series.

      certificate of authentication on this Security.

     

    11.     CUSIP
      NUMBERS

     

    Pursuant
      to a recommendation promulgated by the Committee on Uniform Security
      Identification Procedures, the Company will cause CUSIP numbers to be printed
      on
      the Securities of this series as a convenience to the Holders of the Securities
      of this series.

     

    12.     GOVERNING
      LAW

     

    This
      Security shall be governed by and construed in accordance with the laws of
      the
      State of New York, including Section 5-1401 of the New York General Obligations
      Law, but otherwise without regard to the principles of conflict of laws

    THE
      RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL SECURITY, AND THE
      CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR DEFINITIVE SECURITIES,
      ARE
      AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE
      BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL SECURITY SHALL BE
      ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON.

     

    THIS
      SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER
      REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE OF A
      DEPOSITARY. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE
      NAME
      OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED
      CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS SECURITY
      (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE DEPOSITARY TO A
      NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY
      OR
      ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE
      TO A
      SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY) MAY BE
      REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES. 

     

    UNLESS
      THIS GLOBAL SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
      DEPOSITARY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE
      OR
      PAYMENT, AND ANY DEFINITIVE SECURITY IS ISSUED IN THE NAME OR NAMES AS DIRECTED
      IN WRITING BY THE DEPOSITARY, ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR
      VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL IN AS MUCH AS THE REGISTERED
      OWNER HEREOF, THE DEPOSITARY, HAS AN INTEREST HEREIN.

     

    THIS
      SECURITY HAS BEEN ISSUED IN RELIANCE ON REGULATION S UNDER THE SECURITIES ACT
      AND SHALL BEAR THE FOLLOWING LEGEND UNTIL REMOVABLE IN ACCORDANCE WITH ITS
      TERMS
      AND THE TERMS OF THE INDENTURE.

    THIS
      SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF
      1933,
      AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
      WITHIN THE UNITED STATES OR TO OR FOR THE ACCOUNT OR BENEFIT OF U.S. PERSONS
      EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, EACH
      HOLDER OF THIS SECURITY AND ANY OWNERS OF INTERESTS HEREIN (1) REPRESENTS THAT
      IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE
      SECURITIES ACT), (2) AGREES THAT BEGINNING FROM THE LATER OF (X) THE ORIGINAL
      ISSUE DATE OF THIS SECURITY OR (Y) THE LAST DATE ON WHICH THE COMPANY OR ANY
      AFFILIATE THEREOF WAS THE BENEFICIAL OWNER OF THIS SECURITY (OR ANY PREDECESSOR
      HEREOF) THROUGH THE TIME PERIOD REFERRED TO IN RULE 144(K) UNDER THE SECURITIES
      ACT, IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE
      COMPANY OR ANY AFFILIATE THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN
      COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL
      “ACCREDITED INVESTOR” THAT PRIOR TO SUCH TRANSFER FURNISHED TO THE TRUSTEE A
      SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO
      THE
      RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH LETTER CAN BE
      OBTAINED FROM THE TRUSTEE) AND, IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE
      PRINCIPAL AMOUNT OF SECURITIES AT THE TIME OF TRANSFER OF LESS THAN $250,000,

      OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE
      WITH THE SECURITIES ACT, (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE

      PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT
      TO
      AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES
      THAT
      IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE
      SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. UNLESS THE COMPANY DETERMINES
      OTHERWISE IN ACCORDANCE WITH APPLICABLE LAW, THIS LEGEND WILL BE REMOVED BY
      THE
      COMPANY (1) UPON REQUEST OF THE HOLDER, AFTER THE EXPIRATION OF THE TIME PERIOD
      REFERRED TO IN RULE 144(K) UNDER THE SECURITIES ACT BEGINNING FROM THE LATER

      OFFERED TO PERSONS OTHER THAN DISTRIBUTORS (AS DEFINED IN REGULATION S) AND
      (B)
      THE ORIGINAL ISSUE DATE OF THIS SECURITY. AS USED HEREIN, THE TERMS “OFFSHORE

      ENERGY HOLDINGS COMPANY, a corporation organized under the laws of Iowa (the
      “Company,”
which
      term includes any successor corporation under the Indenture hereinafter referred
      to), for value received, hereby promises to pay to CEDE & Co., or registered
      assigns, the principal amount of [_________] Dollars (such Initial Principal
      Amount, as it may from time to time be adjusted by endorsement on Schedule
      A
      hereto, is hereinafter referred to as the “Principal
      Amount”),
      on
      May 15, 2037, and to pay interest thereon from May 11, 2007, or from the most
      recent Interest Payment Date to which interest has been paid or duly provided
      for, semi-annually on May 15 and November 15 in each year, commencing November
      15, 2007, at the rate of 5.95% per annum, until the Principal Amount hereof
      is
      paid or made available for payment; provided that any Principal Amount and
      premium, and any such installment of interest, which is overdue shall bear
      interest at the rate of 5.95% per annum (or, if lower, the maximum rate legally
      enforceable) from the dates such amounts are due until they are paid or made
      available for payment; provided, further, that if a Registration Default (as
      defined in the Registration Rights Agreement) occurs with respect to this
      Security, interest will accrue on this Security at a rate of 0.5% per annum
      from
      and including the date on which any such Registration Default shall occur,
      until
      but excluding the date on which all Registration Defaults have been cured.
      The
      interest so payable, and punctually paid or duly provided for, on any Interest
      Payment Date will, as provided in such Indenture, be paid to the Person in
      whose
      name this Security (or one or more Predecessor Securities) is registered at
      the
      close of business on the Regular Record Date for such interest, which shall
      be
      the May 1 or November 1 (whether or not a Business Day), as the case may be,
      immediately preceding such Interest Payment Date. Any such interest not so
      punctually paid or duly provided for will forthwith cease to be payable to
      the
      Person in whose name this Security (or one or more Predecessor Securities)
      is
      registered on such Regular Record Date and may be paid to the Person in whose
      name this Security (or one or more Predecessor Securities) is registered at
      the
      close of business on a Special Record Date for the payment of such Defaulted
      Interest to be fixed by the Trustee, notice whereof shall be given to Holders
      of
      Securities of this series not less than 10 days prior to such Special Record
      Date, or be paid at any time in any other lawful manner not inconsistent with
      the requirements of any securities exchange on which the Securities of this
      series may be listed, and upon such notice as may be required by such exchange,
      all as more fully provided in said Indenture. 

     

    Until
      this Regulation S Temporary Global Security is exchanged for one or more
      Regulation S Permanent Global Securities, the Holder hereof shall not be
      entitled to receive payments of interest hereon; until so exchanged in full,
      this Regulation S Temporary Global Security shall in all other respects be
      entitled to the same benefits as other Securities under the
      Indenture.

    Payment
      of the principal of (and premium, if any) and interest, if any, on this Security
      will be made at any place of payment or at the office or agency of the Company
      maintained for that purpose in the Borough of Manhattan, The City of New York,
      in such coin or currency of the United States as at the time of payment is
      legal
      tender for the payment of public and private debts, provided,
      however,
      that
      payment of interest may be made by check mailed to the address of the Person
      entitled thereto as such address shall appear in the Security Register. Payment
      of interest, if any, in respect of this Security may also be made, in the case
      of a Holder of at least U.S. $1,000,000 aggregate principal amount of
      Securities, by wire transfer to a U.S. Dollar account maintained by the Holder
      with a bank in the United States; provided that such Holder elects payment
      by
      wire transfer by giving written notice to the Trustee or Paying Agent to such
      effect designating such account no later than 15 days immediately preceding
      the
      relevant due date for payment (or such other date as the Trustee may accept
      in
      its discretion).

     

    REFERENCE
      IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET FORTH ON THE
      REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME
      EFFECT AS IF SET FORTH AT THIS PLACE.

     

    Unless

      the
      Fifth Supplemental Indenture, dated as of May 11, 2007 (together with the Base
      Indenture, the “Indenture”),
      between the Company and the Trustee, to which Indenture and all indentures

      rights, limitations of rights, duties and immunities thereunder of the Company,
      the Trustee and the Holders of the Securities and of the terms upon which the
      Securities are, and are to be, authenticated and delivered. Terms defined in

      to

      more than 60 days’ notice to the Holders of such Securities as provided in the
      Indenture, at any time, as a whole or in part, at the election of the Company,
      at a redemption price equal to the greater of: (i) 100% of the principal amount
      of the Securities of this series being redeemed or (ii) the sum of the present
      values of the remaining scheduled payments of principal of and interest on
      the
      Securities of this series being redeemed discounted to the Redemption Date
      on a
      semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
      at
      a discount rate equal to the Treasury Yield plus 25 basis points, plus, for

      Yield”

      amount) equal to the Comparable Treasury Price for such Redemption
      Date.

     

    “Comparable
      Treasury Issue”
means
      the United States Treasury security selected by an Independent Investment Banker
      as having a maturity comparable to the remaining term of the Securities of
      this
      series to be redeemed that would be utilized, at the time of selection and
      in
      accordance with customary financial practice, in pricing new issues of corporate
      debt securities of comparable maturity to the remaining term of the Securities
      of this series.

     

    
      
        
        

      

      
        Exhibit
          B-7

        
          

        

      

      
        
        

      

    

     

    “Comparable
      Treasury Price”
means,
      with respect to any Redemption Date, (i) the average of the bid and asked prices
      for the Comparable Treasury Issue (expressed in each case as a percentage of
      its
      principal amount) on the third Business Day in New York City preceding such
      Redemption Date, as set forth in the daily statistical release (or any successor
      release) published by the Federal Reserve Bank of New York and designated
“Composite 3:30 p.m. Quotations for U.S. Government Securities” or (ii) if such
      release (or any successor release) is not published or does not contain such
      prices on such Business Day, the Reference Treasury Dealer Quotation for such
      Redemption Date.

     

    “Independent
      Investment Banker”
means
      an investment banking institution of international standing appointed by the
      Company.

     

    “Reference
      Treasury Dealer”
means
      a
      primary U.S. government securities dealer in New York City appointed by the
      Company.

     

    “Reference
      Treasury Dealer Quotation”
means,
      with respect to the Reference Treasury Dealer and any Redemption Date, the
      average, as determined by the Company, of the bid and asked prices for the
      Comparable Treasury Issue (expressed in each case as a percentage of its
      principal amount and quoted in writing to the Company by such Reference Treasury
      Dealer at 5:00 p.m. on the third Business Day in New York City preceding such
      Redemption Date).

     

    Notice
      of
      redemption pursuant to this paragraph 2 shall be given as provided for in the
      Indenture not less than 30 days nor more than 60 days prior to the Redemption
      Date.

     

    If
      fewer
      than all the Securities of this series are to be redeemed, selection of
      Securities of this series for redemption will be made by the Trustee on a pro
      rata basis.

     

    Unless
      the Company defaults in payment of the Redemption Price, from and after the
      Redemption Date, the Securities of this series or portions thereof called for
      redemption will cease to bear interest, and the Holders thereof will have no
      right in respect of such Securities of this series except the right to receive
      the Redemption Price thereof.

     

    In
      the
      event of redemption of this Security in part only, the Trustee will reduce
      the
      Principal Amount hereof by endorsement on Schedule A hereto such that the
      Principal Amount shown on Schedule A after such endorsement will reflect only
      the unredeemed portion hereof.

     

    3.     DEFEASANCE

     

    The
      Indenture contains provisions for defeasance of (a) the entire indebtedness
      of
      this Security and (b) certain restrictive covenants upon compliance by the
      Company with certain conditions set forth therein.

     

    4.     DEFAULTS
      AND REMEDIES

     

    If
      an
      Event of Default with respect to Securities of this series shall occur and
      be
      continuing, the principal of the Securities of this series may be declared
      due
      and payable in the manner and with the effect provided in the Indenture. At
      any
      time after such declaration of acceleration with respect to Securities of this
      series has been made, but before a judgment or decree for payment of money
      has
      been obtained by the Trustee as provided in the Indenture, if all Events of
      Default with respect to Securities of this series have been cured or waived
      (other than the non-payment of principal of the Securities of this series which
      has become due solely by reason of such declaration of acceleration) then,
      and
      in every such case, the Holders of a majority in aggregate principal amount
      of
      the Outstanding securities under the Indenture may, by written notice to the
      Company and to the Trustee, rescind and annul such declaration and its
      consequences on behalf of all of the Holders, but no such rescission or
      annulment shall extend to or affect any subsequent default or impair any right
      consequent thereon.

     

    
      
        
        

      

      
        Exhibit
          B-8

        
          

        

      

      
        
        

      

    

     

    As
      provided in and subject to the provisions of the Indenture, the Holder of this
      Security shall not have the right to institute any proceeding, judicial or
      otherwise, with respect to the Indenture, or for the appointment of a receiver,
      or trustee or for any other remedy thereunder, unless (a) such Holder shall
      have
      previously given the Trustee written notice of a continuing Event of Default
      with respect to the Securities, (b) the Holders of not less than 33% or a
      majority, as applicable, in principal amount of the Securities at the time
      Outstanding under the Indenture shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default as Trustee, (c)
      such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
      against the costs, expenses and liabilities to be incurred in compliance with
      such request, (d) the Trustee shall not have received from the Holders of a
      majority in principal amount of Securities at the time Outstanding under the
      Indenture a direction inconsistent with such request and (e) the Trustee for
      90
      days after its receipt of such notice and offer of indemnity from the Holder,
      and request from the Holders, shall have failed to institute any such
      proceeding. The foregoing shall not apply to certain suits described in the
      Indenture, including any suit instituted by the Holder of this Security for
      the
      enforcement of any payment of principal hereof or any premium or interest hereon
      on or after the respective due dates expressed herein.

     

    5.     AMENDMENT
      AND WAIVER

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the Indenture or any supplemental indenture
      or
      the rights and obligations of the Company and rights of the Holders of the
      Securities of any series at any time by the Company and the Trustee with the
      consent of the Holders of a majority in aggregate principal amount of the
      Securities at the time Outstanding of each series to be affected. The Indenture
      also contains provisions permitting the Holders of specified percentages in
      principal amount of the Securities of each series at the time Outstanding,
      on
      behalf of the Holders of all Securities of such series, to waive compliance
      by
      the Company with certain provisions of the Indenture and certain past defaults
      under the Indenture and their consequences. Any such consent or waiver by the
      Holder of this Security shall be conclusive and binding upon such Holder and
      upon all future Holders of this Security and of any Security issued upon the
      registration of transfer hereof or in exchange herefor or in lieu hereof,
      whether or not notation of such consent or waiver is made upon this
      Security.

     

    No
      reference herein to the Indenture and no provision of this Security or of the
      Indenture shall alter or impair the obligation of the Company, which is absolute
      and unconditional, to pay the principal of (and premium, if any) and interest,
      if any, on this Security at the times, place and rate, and in the coin or
      currency, herein prescribed.

    6.     TRANSFER
      AND EXCHANGE; DENOMINATIONS

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,

      registration of transfer at the office or agency of the Company in any place
      where the principal of (and premium, if any) and interest, if any, on this
      Security are payable, duly endorsed by, or accompanied by a written instrument
      of transfer in form satisfactory to the Company and the Security Registrar
      duly
      executed by, the Holder hereof or his attorney duly authorized in writing,
      and
      thereupon one or more new Securities of this series and of like tenor, of
      authorized denominations and for the same aggregate principal amount, will
      be
      issued to the designated transferee or transferees.

     

    The
      Securities of the series of which this Security is a part are issuable only
      in
      registered form, without coupons, in denominations of $2,000 and any integral
      multiple of $1,000 in excess thereof. 

     

    No
      service charge shall be made for any such registration of transfer or exchange,
      but the Company may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    Prior
      to
      due presentment of this Security for registration of transfer, the Company,
      the
      Trustee and any agent of the Company or the Trustee may treat the Person in
      whose name this Security is registered as the owner hereof for all purposes,
      whether or not this security be overdue, and neither the Company, the Trustee
      nor any such agent shall be affected by notice to the contrary.

     

    This
      Regulation S Temporary Global Security is exchangeable in whole or in part
      for
      one or more Global Securities only (i) on or after the termination of the 40-day
      distribution compliance period (as defined in Regulation S) and (ii) upon
      presentation of certificates (accompanied by an Opinion of Counsel, if
      applicable) required by Article 2 of the Indenture. Upon exchange of this
      Regulation S Temporary Global Security for one or more Global Securities, the
      Trustee shall cancel this Regulation S Temporary Global Security.

     

    7.     SUCCESSOR
      OBLIGORS

     

    When
      a
      successor assumes all the obligations of its predecessor under the Securities
      of
      this series and the Indenture in accordance with the terms of the Indenture,
      the
      predecessor will be released from those obligations.

     

    8.     TRUSTEE
      DEALINGS WITH THE COMPANY

     

    The
      Trustee under the Indenture, in its individual or any other capacity, may become
      the owner or pledgee of Securities of this series and may otherwise deal with
      the Company, its Subsidiaries or their respective Affiliates as if it were
      not
      the Trustee.

      RECOURSE AGAINST OTHERS

     

    No
      stockholder, director, officer, employee, incorporator or Affiliate of the
      Company shall have any liability for any obligation of the Company under the
      Securities of this series or the Indenture or for any claim based on, in respect
      of or by reason of, such obligations or their creation. Each Holder of the
      Securities of this series by accepting a Security of this series waives and
      releases all such liability. The waiver and release are part of the
      consideration for the issuance of the Securities of this series.

     

    10.     AUTHENTICATION

     

    This
      Security shall not be valid until the Trustee or authenticating agent signs

      NUMBER

      Security shall be governed by and construed in accordance with the laws of
      the
      State of New York, including Section 5-1401 of the New York General Obligations
      Law, but otherwise without regard to the principles of conflict of laws
      thereof.

     

    13.     DEFINED
      TERMS

      Amount, as it may from time to time be adjusted by endorsement on Schedule
      A
      hereto, is hereinafter referred to as the “Principal
      Amount”),
      on
      May 15, 2037, and to pay interest thereon from May 11, 2007, or from the most
      recent Interest Payment Date to which interest has been paid or duly provided
      for, semi-annually on May 15 and November 15 in each year, commencing November
      15, 2007, at the rate of 5.95% per annum until the Principal Amount hereof
      is
      paid or made available for payment; provided that any Principal Amount and
      premium, and any such installment of interest, which is overdue shall bear
      interest at the rate of 5.95% per annum (or, if lower, the maximum rate legally
      enforceable) from the dates such amounts are due until they are paid or made
      available for payment; provided, further, that if a Registration Default (as
      defined in the Registration Rights Agreement) occurs with respect to this
      Security, interest will accrue on this Security at a rate of 0.5% per annum
      from
      and including the date on which any such Registration Default shall occur,
      until
      but excluding the date on which all Registration Defaults have been cured.
      The
      interest so payable, and punctually paid or duly provided for, on any Interest
      Payment Date will, as provided in such Indenture, be paid to the Person in
      whose
      name this Security (or one or more Predecessor Securities) is registered at
      the
      close of business on the Regular Record Date for such interest, which shall
      be
      the May 1 or November 1 (whether or not a Business Day), as the case may be,
      immediately preceding such Interest Payment Date. Any such interest not so
      punctually paid or duly provided for will forthwith cease to be payable to
      the
      Person in whose name this Security (or one or more Predecessor Securities)
      is
      registered on such Regular Record Date and may be paid to the Person in whose
      name this Security (or one or more Predecessor Securities) is registered at
      the
      close of business on a Special Record Date for the payment of such Defaulted
      Interest to be fixed by the Trustee, notice whereof shall be given to Holders
      of
      Securities of this series not less than 10 days prior to such Special Record
      Date, or be paid at any time in any other lawful manner not inconsistent with
      the requirements of any securities exchange on which the Securities of this
      series may be listed, and upon such notice as may be required by such exchange,
      all as more fully provided in said Indenture. 

     

    Payment
      of the principal of (and premium, if any) and interest, if any, on this Security
      will be made at any place of payment or at the office or agency of the Company
      maintained for that purpose in the Borough of Manhattan, The City of New York,
      in such coin or currency of the United States as at the time of payment is
      legal
      tender for the payment of public and private debts, provided,
      however,
      that
      payment of interest may be made by check mailed to the address of the Person
      entitled thereto as such address shall appear in the Security Register. Payment
      of interest, if any, in respect of this Security may also be made, in the case
      of a Holder of at least U.S. $1,000,000 aggregate principal amount of
      Securities, by wire transfer to a U.S. Dollar account maintained by the Holder
      with a bank in the United States; provided that such Holder elects payment
      by
      wire transfer by giving written notice to the Trustee or Paying Agent to such
      effect designating such account no later than 15 days immediately preceding
      the
      relevant due date for payment (or such other date as the Trustee may accept

      its discretion).

      between the Company and the Trustee, to which Indenture and all indentures
      supplemental thereto reference is hereby made for a statement of the respective
      rights, limitations of rights, duties and immunities thereunder of the Company,
      the Trustee and the Holders of the Securities and of the terms upon which the
      Securities are, and are to be, authenticated and delivered. Terms defined in

    The
      Securities of this series are subject to redemption upon not less than 30 or
      more than 60 days’ notice to the Holders of such Securities as provided in the
      Indenture, at any time, as a whole or in part, at the election of the Company
      at
      any time, at a redemption price equal to the greater of: (i) 100% of the
      principal amount of the Securities of this series being redeemed or (ii) the
      sum
      of the present values of the remaining scheduled payments of principal of and
      interest on the Securities of this series being redeemed discounted to the
      Redemption Date on a semiannual basis (assuming a 360-day year consisting of
      twelve 30-day months) at a discount rate equal to the Treasury Yield plus 25
      basis points, plus, for (i) or (ii) above, whichever is applicable, accrued
      interest on the Securities of this series to the Redemption Date.

     

    “Treasury
      Yield”
means,
      with respect to any Redemption Date, the rate per annum equal to the semiannual
      equivalent yield to maturity of the Comparable Treasury Issue, assuming a price
      for the Comparable Treasury Issue (expressed as a percentage of its principal
      amount) equal to the Comparable Treasury Price for such Redemption
      Date.

     

    “Comparable
      Treasury Issue”
means
      the United States Treasury security selected by an Independent Investment Banker
      as having a maturity comparable to the remaining term of the Securities of
      this
      series to be redeemed that would be utilized, at the time of selection and
      in
      accordance with customary financial practice, in pricing new issues of corporate
      debt securities of comparable maturity to the remaining term of the Securities
      of this series.

    “Comparable
      Treasury Price”
means,
      with respect to any Redemption Date, (i) the average of the bid and asked prices
      for the Comparable Treasury Issue (expressed in each case as a percentage of
      its
      principal amount) on the third Business Day in New York City preceding such
      Redemption Date, as set forth in the daily statistical release (or any successor
      release) published by the Federal Reserve Bank of New York and designated
“Composite 3:30 p.m. Quotations for U.S. Government Securities” or (ii) if such
      release (or any successor release) is not published or does not contain such
      prices on such Business Day, the Reference Treasury Dealer Quotation for such
      Redemption Date.

     

    “Independent
      Investment Banker”
means
      an investment banking institution of international standing appointed by the
      Company.

     

    “Reference
      Treasury Dealer”
means
      a
      primary U.S. government securities dealer in New York City appointed by the
      Company.

     

    “Reference
      Treasury Dealer Quotation”
means,
      with respect to the Reference Treasury Dealer and any Redemption Date, the
      average, as determined by the Company, of the bid and asked prices for the
      Comparable Treasury Issue (expressed in each case as a percentage of its
      principal amount and quoted in writing to the Company by such Reference Treasury
      Dealer at 5:00 p.m. on the third Business Day in New York City preceding such
      Redemption Date).

     

    Notice
      of
      redemption pursuant to this paragraph 2 shall be given as provided for in the
      Indenture not less than 30 days nor more than 60 days prior to the Redemption
      Date.

     

    If
      fewer
      than all the Securities of this series are to be redeemed, selection of
      Securities of this series for redemption will be made by the Trustee on a pro
      rata basis.

     

    Unless
      the Company defaults in payment of the Redemption Price, from and after the
      Redemption Date, the Securities of this series or portions thereof called for
      redemption will cease to bear interest, and the Holders thereof will have no
      right in respect of such Securities of this series except the right to receive
      the Redemption Price thereof.

     

    In
      the
      event of redemption of this Security in part only, the Trustee will reduce
      the
      Principal Amount hereof by endorsement on Schedule A hereto such that the
      Principal Amount shown on Schedule A after such endorsement will reflect only
      the unredeemed portion hereof.

     

    3.
        DEFEASANCE

     

    The
      Indenture contains provisions for defeasance of (a) the entire indebtedness
      of
      this Security and (b) certain restrictive covenants upon compliance by the
      Company with certain conditions set forth therein.

        DEFAULTS
      AND REMEDIES

     

    If
      an
      Event of Default with respect to Securities of this series shall occur and
      be
      continuing, the principal of the Securities of this series may be declared
      due
      and payable in the manner and with the effect provided in the Indenture. At
      any
      time after such declaration of acceleration with respect to Securities of this
      series has been made, but before a judgment or decree for payment of money
      has
      been obtained by the Trustee as provided in the Indenture, if all Events of
      Default with respect to Securities of this series have been cured or waived
      (other than the non-payment of principal of the Securities of this series which
      has become due solely by reason of such declaration of acceleration) then,
      and
      in every such case, the Holders of a majority in aggregate principal amount
      of
      the Outstanding securities of such series may, by written notice to the Company
      and to the Trustee, rescind and annul such declaration and its consequences
      on
      behalf of all of the Holders, but no such rescission or annulment shall extend
      to or affect any subsequent default or impair any right consequent
      thereon.

    As
      provided in and subject to the provisions of the Indenture, the Holder of this
      Security shall not have the right to institute any proceeding, judicial or
      otherwise, with respect to the Indenture, or for the appointment of a receiver,
      or trustee or for any other remedy thereunder, unless (a) such Holder shall
      have
      previously given the Trustee written notice of a continuing Event of Default
      with respect to the securities, (b) the Holders of not less than 33% or a
      majority, as applicable, in principal amount of the Securities at the time
      Outstanding under the Indenture shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default as Trustee, (c)
      such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
      against the costs, expenses and liabilities to be incurred in compliance with
      such request, (d) the Trustee shall not have received from the Holders of a
      majority in principal amount of Securities at the time Outstanding under the
      Indenture a direction inconsistent with such request and (e) the Trustee for
      90
      days after its receipt of such notice and offer of indemnity from the Holder,
      and request from the Holders shall have failed to institute any such proceeding.
      The foregoing shall not apply to certain suits described in the Indenture,
      including any suit instituted by the Holder of this Security for the enforcement
      of any payment of principal hereof or any premium or interest hereon on or

      thereof and the modification of the Indenture or any supplemental indenture
      or
      the rights and obligations of the Company and rights of the Holders of the
      Securities of any series at any time by the Company and the Trustee with the
      consent of the Holders of a majority in aggregate principal amount of the
      Securities at the time Outstanding of each series to be affected. The Indenture
      also contains provisions permitting the Holders of specified percentages in
      principal amount of the Securities of each series at the time Outstanding,
      on
      behalf of the Holders of all Securities of such series, to waive compliance
      by
      the Company with certain provisions of the Indenture and certain past defaults
      under the Indenture and their consequences. Any such consent or waiver by the
      Holder of this Security shall be conclusive and binding upon such Holder and
      upon all future Holders of this Security and of any Security issued upon the
      registration of transfer hereof or in exchange herefor or in lieu hereof,
      whether or not notation of such consent or waiver is made upon this
      Security.

     

    No
      reference herein to the Indenture and no provision of this Security or of the
      Indenture shall alter or impair the obligation of the Company, which is absolute
      and unconditional, to pay the principal of (and premium, if any) and interest,
      if any, on this Security at the times, place and rate, and in the coin or
      currency, herein prescribed.

    6.
        TRANSFER
      AND EXCHANGE; DENOMINATIONS

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,
      the transfer of a Security of the series of which this Security is a part is
      registrable in the Security Register, upon surrender of this Security for
      registration of transfer at the office or agency of the Company in any place
      where the principal of (and premium, if any) and interest, if any, on this
      Security are payable, duly endorsed by, or accompanied by a written instrument
      of transfer in form satisfactory to the Company and the Security Registrar
      duly
      executed by, the Holder hereof or his attorney duly authorized in writing,
      and
      thereupon one or more new Securities of this series and like tenor, of
      authorized denominations and for the same aggregate principal amount, will
      be
      issued to the designated transferee or transferees.

     

    The
      Securities of the series of which this Security is a part are issuable only
      in
      registered form, without coupons, in denominations of $2,000 and any integral
      multiple of $1,000 in excess thereof. 

     

    No
      service charge shall be made for any such registration of transfer or exchange,
      but the Company may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    Prior
      to
      due presentment of this Security for registration of transfer, the Company,
      the
      Trustee and any agent of the Company or the Trustee may treat the Person in
      whose name this Security is registered as the owner hereof for all purposes,
      whether or not this security be overdue, and neither the Company, the Trustee
      nor any such agent shall be affected by notice to the contrary.

    When
      a
      successor assumes all the obligations of its predecessor under the Securities
      of
      this series and the Indenture in accordance with the terms of the Indenture,
      the
      predecessor will be released from those obligations.

      DEALINGS WITH THE COMPANY

     

    The

      the owner or pledgee of Securities of this series and may otherwise deal with
      the Company, its Subsidiaries or their respective Affiliates as if it were
      not
      the Trustee.

     

    9.
        NO
      RECOURSE AGAINST OTHERS

     

    No
      stockholder, director, officer, employee, incorporator or Affiliate of the
      Company shall have any liability for any obligation of the Company under the
      Securities of this series or the Indenture or for any claim based on, in respect
      of or by reason of, such obligations or their creation. Each Holder of the
      Securities of this series by accepting a Security of this series waives and
      releases all such liability. The waiver and release are part of the
      consideration for the issuance of the Securities of this series.

      or
      its registered assigns] the principal sum of [__________] Dollars (the
“Principal
      Amount”)
      on May
      15, 2037, and to pay interest thereon from May 11, 2007, or from the most recent
      Interest Payment Date to which interest has been paid or duly provided for,
      semi-annually on May 15 and November 15 in each year, commencing November 15,
      2007, at the rate of 5.95% per annum, until the Principal Amount hereof is
      paid
      or made available for payment; provided that any Principal Amount and premium,
      and any such installment of interest, which is overdue shall bear interest
      at
      the rate of 5.95% per annum (or, if lower, the maximum rate legally enforceable)
      from the dates such amounts are due until they are paid or made available for
      payment; provided, further, that if a Registration Default (as defined in the
      Registration Rights Agreement) occurs with respect to this Security, interest
      will accrue on this Security at a rate of 0.5% per annum from and including
      the
      date on which any such Registration Default shall occur, until but excluding
      the
      date on which all Registration Defaults have been cured. The interest so
      payable, and punctually paid or duly provided for, on any Interest Payment
      Date
      will, as provided in such Indenture, be paid to the Person in whose name this
      Security (or one or more Predecessor Securities) is registered at the close
      of
      business on the Regular Record Date for such interest, which shall be the May
      1
      or November 1 (whether or not a Business Day), as the case may be, immediately
      preceding such Interest Payment Date. Any such interest not so punctually paid
      or duly provided for will forthwith cease to be payable to the Person in whose
      name this Security (or one or more Predecessor Securities) is registered on
      such
      Regular Record Date and may be paid to the Person in whose name this Security
      (or one or more Predecessor Securities) is registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest to be fixed
      by the Trustee, notice whereof shall be given to Holders of Securities of this
      series not less than 10 days prior to such Special Record Date, or be paid
      at
      any time in any other lawful manner not inconsistent with the requirements
      of
      any securities exchange on which the Securities of this series may be listed,
      and upon such notice as may be required by such exchange, all as more fully
      provided in said Indenture.

      the
      Fifth Supplemental Indenture, dated as of May 11, 2007 (together with the Base
      Indenture, the “Indenture”),
      between the Company and the Trustee, to which Indenture and all indentures
      supplemental thereto reference is hereby made for a statement of the respective
      rights, limitations of rights, duties and immunities thereunder of the Company,
      the Trustee and the Holders of the Securities and of the terms upon which the
      Securities are, and are to be, authenticated and delivered. Terms defined in
      the
      Indenture which are not defined herein are used with the meanings assigned
      to
      them in the Indenture. This Security is one of the series designated on the
      face
      hereof.

     

    2.     OPTIONAL
      REDEMPTION

     

    The
      Securities of this series are subject to redemption upon not less than 30 or
      more than 60 days’ notice to the Holders of such Securities as provided in the
      Indenture, at any time, as a whole or in part, at the election of the Company,

      values of the remaining scheduled payments of principal of and interest on
      the
      Securities of this series being redeemed discounted to the Redemption Date
      on a
      semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
      at
      a discount rate equal to the Treasury Yield plus 25 basis points, plus, for
      (i)
      or (ii) above, whichever is applicable, accrued interest on the Securities

    “Treasury
      Yield”
means,
      with respect to any Redemption Date, the rate per annum equal to the semiannual

      amount) equal to the Comparable Treasury Price for such Redemption
      Date.

     

    “Comparable
      Treasury Issue”
means
      the United States Treasury security selected by an Independent Investment Banker
      as having a maturity comparable to the remaining term of the Securities of
      this
      series to be redeemed that would be utilized, at the time of selection and
      in
      accordance with customary financial practice, in pricing new issues of corporate
      debt securities of comparable maturity to the remaining term of the Securities
      of this series.

     

    “Comparable
      Treasury Price”
means,
      with respect to any Redemption Date, (i) the average of the bid and asked prices
      for the Comparable Treasury Issue (expressed in each case as a percentage of
      its
      principal amount) on the third Business Day in New York City preceding such
      Redemption Date, as set forth in the daily statistical release (or any successor
      release) published by the Federal Reserve Bank of New York and designated
“Composite 3:30 p.m. Quotations for U.S. Government Securities” or (ii) if such
      release (or any successor release) is not published or does not contain such
      prices on such Business Day, the Reference Treasury Dealer Quotation for such
      Redemption Date.

     

    
      
        
        

      

      
        Exhibit
          D-7

        
          

        

      

      
        
        

      

    

     

    “Independent
      Investment Banker”
means
      an investment banking institution of international standing appointed by the
      Company.

     

    “Reference
      Treasury Dealer”
means
      a
      primary U.S. government securities dealer in New York City appointed by the
      Company.

     

    “Reference
      Treasury Dealer Quotation”
means,
      with respect to the Reference Treasury Dealer and any Redemption Date, the
      average, as determined by the Company, of the bid and asked prices for the
      Comparable Treasury Issue (expressed in each case as a percentage of its
      principal amount and quoted in writing to the Company by such Reference Treasury
      Dealer at 5:00 p.m. on the third Business Day in New York City preceding such
      Redemption Date).

     

    Notice
      of
      redemption pursuant to this paragraph 2 shall be given as provided for in the
      Indenture not less than 30 days nor more than 60 days prior to the Redemption
      Date.

     

    If
      fewer
      than all the Securities of this series are to be redeemed, selection of
      Securities of this series for redemption will be made by the Trustee on a pro
      rata basis.

     

    Unless
      the Company defaults in payment of the Redemption Price, from and after the
      Redemption Date, the Securities of this series or portions thereof called for
      redemption will cease to bear interest, and the Holders thereof will have no
      right in respect of such Securities of this series except the right to receive
      the Redemption Price thereof.

     

    3.     DEFEASANCE

     

    The
      Indenture contains provisions for defeasance of (a) the entire indebtedness
      of
      this Security and (b) certain restrictive covenants upon compliance by the
      Company with certain conditions set forth therein.

     

    4.     DEFAULTS
      AND REMEDIES

     

    If
      an
      Event of Default with respect to Securities of this series shall occur and
      be
      continuing, the principal of the Securities of this series may be declared
      due
      and payable in the manner and with the effect provided in the Indenture. At
      any
      time after such declaration of acceleration with respect to Securities of this
      series has been made, but before a judgment or decree for payment of money
      has
      been obtained by the Trustee as provided in the Indenture, if all Events of
      Default with respect to Securities of this series have been cured or waived
      (other than the non-payment of principal of the Securities of this series which
      has become due solely by reason of such declaration of acceleration) then and
      in
      every such case, the Holders of a majority in aggregate principal amount of
      the
      Outstanding securities of such series may, by written notice to the Company
      and
      to the Trustee, rescind and annul such declaration and its consequences on
      behalf of all of the Holders, but no such rescission or annulment shall extend
      to or affect any subsequent default or impair any right consequent
      thereon.

     

     

    
      
        
        

      

      
        Exhibit
          D-8

        
          

        

      

      
        
        

      

    

     

     

    As
      provided in and subject to the provisions of the Indenture, the Holder of this
      Security shall not have the right to institute any proceeding, judicial or
      otherwise, with respect to the Indenture, or for the appointment of a receiver
      or trustee or for any other remedy thereunder, unless (a) such Holder shall
      have
      previously given the Trustee written notice of a continuing Event of Default
      with respect to the Securities, (b) the Holders of not less than 33% or a
      majority, as applicable, in principal amount of the Securities at the time
      Outstanding under the Indenture shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default as Trustee, (c)
      such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
      against the costs, expenses and liabilities to be incurred in compliance with
      such request, (d) the Trustee shall not have received from the Holders of a
      majority in principal amount of Securities at the time Outstanding under the
      Indenture a direction inconsistent with such request and (e) the Trustee for
      90
      days after its receipt of such notice and offer of indemnity from the Holder,
      and request from the Holders, shall have failed to institute any such
      proceeding. The foregoing shall not apply to certain suits described in the
      Indenture, including any suit instituted by the Holder of this Security for
      the
      enforcement of any payment of principal hereof or any premium or interest hereon
      on or after the respective due dates expressed herein.

     

    5.     AMENDMENT
      AND WAIVER

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the Indenture or any supplemental indenture
      or

      Securities of any series at any time by the Company and the Trustee with the
      consent of the Holders of a majority in aggregate principal amount of the
      Securities at the time Outstanding of each series to be affected. The Indenture
      also contains provisions permitting the Holders of specified percentages in
      principal amount of the Securities of each series at the time Outstanding,
      on
      behalf of the Holders of all Securities of such series, to waive compliance
      by
      the Company with certain provisions of the Indenture and certain past defaults
      under the Indenture and their consequences. Any such consent or waiver by the
      Holder of this Security shall be conclusive and binding upon such Holder and
      upon all future Holders of this Security and of any Security issued upon the
      registration of transfer hereof or in exchange herefor or in lieu hereof,
      whether or not notation of such consent or waiver is made upon this
      Security.

     

    No
      reference herein to the Indenture and no provision of this Security or of the
      Indenture shall alter or impair the obligation of the Company, which is absolute
      and unconditional, to pay the principal of (and premium, if any) and interest,
      if any, on this Security at the times, place and rate, and in the coin or
      currency, herein prescribed.

      of the Company in any place where the principal of (and premium, if any) and
      interest, if any, on this Security are payable, duly endorsed by, or accompanied
      by a written instrument of transfer in form satisfactory to the Company and
      the
      Security Registrar duly executed by, the Holder hereof or his attorney duly
      authorized in writing, and thereupon one or more new Securities of this series
      and of like tenor, of authorized denominations and for the same aggregate
      principal amount, will be issued to the designated transferee or
      transferees.

      multiple of $1,000 in excess thereof.

     

    No
      service charge shall be made for any such registration of transfer or exchange,
      but the Company may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    Prior
      to
      due presentment of this Security for registration of transfer, the Company,
      the
      Trustee and any agent of the Company or the Trustee may treat the Person in
      whose name this Security is registered as the owner hereof for all purposes,
      whether or not this Security be overdue, and neither the Company, the Trustee
      nor any such agent shall be affected by notice to the contrary.

     

    7.     SUCCESSOR
      OBLIGORS

     

    When
      a
      successor assumes all the obligations of its predecessor under the Securities
      of
      this series and the Indenture in accordance with the terms of the Indenture,
      the
      predecessor will be released from those obligations.

      DEALINGS WITH THE COMPANY

     

    The
      Trustee under the Indenture, in its individual or any other capacity, may become
      the owner or pledgee of Securities of this series and may otherwise deal with

      not
      the Trustee.

     

    9.     NO
      RECOURSE AGAINST OTHERS

     

    No
      stockholder, director, officer, employee, incorporator or Affiliate of the
      Company shall have any liability for any obligation of the Company under the
      Securities of this series or the Indenture or for any claim based on, in respect
      of or by reason of, such obligations or their creation. Each Holder of the
      Securities of this series by accepting a Security of this series waives and
      releases all such liability. The waiver and release are part of the
      consideration for the issuance of the Securities of this series.

     

    10.     AUTHENTICATION

     

    This
      Security shall not be valid until the Trustee or authenticating agent signs

      of this series.

      ENERGY HOLDINGS COMPANY, a corporation organized under the laws of Iowa (the
      “Company,”
which
      term includes any successor corporation under the Indenture hereinafter referred
      to), for value received, hereby promises to pay to CEDE & Co., or registered
      assigns, the principal amount of [________] Dollars (such Initial Principal
      Amount, as it may from time to time be adjusted by endorsement on Schedule
      A
      hereto, is hereinafter referred to as the “Principal
      Amount”)
      on May
      15, 2037, and to pay interest thereon from May 11, 2007, or from the most recent
      Interest Payment Date to which interest has been paid or duly provided for,
      semi-annually on May 15 and November 15 in each year, commencing November 15,
      2007, at the rate of 5.95% per annum, until the Principal Amount hereof is
      paid
      or made available for payment; provided that any Principal Amount and premium,
      and any such installment of interest, which is overdue shall bear interest
      at
      the rate of 5.95% per annum (or, if lower, the maximum rate legally enforceable)
      from the dates such amounts are due until they are paid or made available for
      payment. The interest so payable, and punctually paid or duly provided for,
      on
      any Interest Payment Date will, as provided in such Indenture, be paid to the
      Person in whose name this Security (or one or more Predecessor Securities)
      is
      registered at the close of business on the Regular Record Date for such
      interest, which shall be the May 1 or November 1 (whether or not a Business
      Day), as the case may be, immediately preceding such Interest Payment Date.
      Any
      such interest not so punctually paid or duly provided for will forthwith cease
      to be payable to the Person in whose name this Security (or one or more
      Predecessor Securities) is registered on such Regular Record Date and may be
      paid to the Person in whose name this Security (or one or more Predecessor
      Securities) is registered at the close of business on a Special Record Date
      for
      the payment of such Defaulted Interest to be fixed by the Trustee, notice
      whereof shall be given to Holders of Securities of this series not less than
      10
      days prior to such Special Record Date, or be paid at any time in any other
      lawful manner not inconsistent with the requirements of any securities exchange
      on which the Securities of this series may be listed, and upon such notice
      as
      may be required by such exchange, all as more fully provided in said
      Indenture.

     

    Payment
      of the principal of (and premium, if any) and interest, if any, on this Security
      will be made at any place of payment or at the office or agency of the Company
      maintained for that purpose in the Borough of Manhattan, The City of New York,
      in such coin or currency of the United States as at the time of payment is
      legal
      tender for the payment of public and private debts, provided,
      however,
      that,
      payment of interest may be made by check mailed to the address of the Person
      entitled thereto as such address shall appear in the Security Register. Payment
      of interest, if any, in respect of this Security may also be made, in the case
      of a Holder of at least U.S. $1,000,000 aggregate principal amount of
      Securities, by wire transfer to a U.S. Dollar account maintained by the Holder
      with a bank in the United States; provided that such Holder elects payment
      by
      wire transfer by giving written notice to the Trustee or Paying Agent to such
      effect designating such account no later than 15 days immediately preceding
      the
      relevant due date for payment (or such other date as the Trustee may accept
      in
      its discretion).

      accordance with customary financial practice, in pricing new issues of corporate

      of this series.

        release (or any successor release) is not published or does not contain such
        prices on such Business Day, the Reference Treasury Dealer Quotation for

      rata basis.

     

    Unless
      the Company defaults in payment of the Redemption Price, from and after the
      Redemption Date, the Securities of this series or portions thereof called for
      redemption will cease to bear interest, and the Holders thereof will have no
      right in respect of such Securities of this series except the right to receive
      the Redemption Price thereof.

     

    3.     DEFEASANCE

      Indenture contains provisions for defeasance of (a) the entire indebtedness

      be
      continuing, the principal of the Securities of this series may be declared
      due
      and payable in the manner and with the effect provided in the Indenture. At
      any
      time after such declaration of acceleration with respect to Securities of this
      series has been made, but before a judgment or decree for payment of money
      has
      been obtained by the Trustee as provided in the Indenture, if all Events of
      Default with respect to Securities of this series have been cured or waived
      (other than the non-payment of principal of the Securities of this series which
      has become due solely by reason of such declaration of acceleration) then and
      in
      every such case, the Holders of a majority in aggregate principal amount of
      the
      Outstanding securities of such series may, by written notice to the Company
      and
      to the Trustee, rescind and annul such declaration and its consequences on
      behalf of all of the Holders, but no such rescission or annulment shall extend
      to or affect any subsequent default or impair any right consequent
      thereon.

     

    
      
        
           

        

      

      
        Exhibit

    As
      provided in and subject to the provisions of the Indenture, the Holder of this
      Security shall not have the right to institute any proceeding, judicial or
      otherwise, with respect to the Indenture, or for the appointment of a receiver
      or trustee or for any other remedy thereunder, unless (a) such Holder shall
      have
      previously given the Trustee written notice of a continuing Event of Default
      with respect to the Securities, (b) the Holders of not less than 33% or a
      majority, as applicable, in principal amount of the Securities at the time
      Outstanding under the Indenture shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default as Trustee, (c)
      such Holder shall have offered the Trustee indemnity satisfactory to the Trustee
      against the costs, expenses and liabilities to be incurred in compliance with
      such request, (d) the Trustee shall not have received from the Holders of a
      majority in principal amount of Securities at the time Outstanding under the
      Indenture a direction inconsistent with such request and (e) the Trustee for
      90
      days after its receipt of such notice and offer of indemnity from the Holder,
      and request from the Holders, shall have failed to institute any such
      proceeding. The foregoing shall not apply to certain suits described in the
      Indenture, including any suit instituted by the Holder of this Security for
      the
      enforcement of any payment of principal hereof or any premium or interest hereon
      on or after the respective due dates expressed herein.

     

    5.     AMENDMENT
      AND WAIVER

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the Indenture or any supplemental indenture
      or
      the rights and obligations of the Company and rights of the Holders of the
      Securities of any series at any time by the Company and the Trustee with the
      consent of the Holders of a majority in aggregate principal amount of the
      Securities at the time Outstanding of each series to be affected. The Indenture
      also contains provisions permitting the Holders of specified percentages in
      principal amount of the Securities of each series at the time Outstanding,
      on
      behalf of the Holders of all Securities of such series, to waive compliance
      by
      the Company with certain provisions of the Indenture and certain past defaults
      under the Indenture and their consequences. Any such consent or waiver by the
      Holder of this Security shall be conclusive and binding upon such Holder and
      upon all future Holders of this Security and of any Security issued upon the
      registration of transfer hereof or in exchange herefor or in lieu hereof,
      whether or not notation of such consent or waiver is made upon this
      Security.

     

    No
      reference herein to the Indenture and no provision of this Security or of the
      Indenture shall alter or impair the obligation of the Company, which is absolute
      and unconditional, to pay the principal of (and premium, if any) and interest,
      if any, on this Security at the times, place and rate, and in the coin or
      currency, herein prescribed.

    6.     TRANSFER
      AND EXCHANGE; DENOMINATIONS

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,
      the transfer of this Security is registrable in the Security Register, upon
      surrender of this Security for registration of transfer at the office or agency
      of the Company in any place where the principal of (and premium, if any) and
      interest, if any, on this Security are payable, duly endorsed by, or accompanied
      by a written instrument of transfer in form satisfactory to the Company and
      the
      Security Registrar duly executed by, the Holder hereof or his attorney duly
      authorized in writing, and thereupon one or more new Securities of this series
      and of like tenor, of authorized denominations and for the same aggregate
      principal amount, will be issued to the designated transferee or
      transferees.

     

    The
      Securities of the series of which this Security is a part are issuable only
      in
      registered form, without coupons, in denominations of $2,000 and any integral
      multiple of $1,000 in excess thereof.

     

    No
      service charge shall be made for any such registration of transfer or exchange,
      but the Company may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    Prior
      to
      due presentment of this Security for registration of transfer, the Company,
      the
      Trustee and any agent of the Company or the Trustee may treat the Person in
      whose name this Security is registered as the owner hereof for all purposes,
      whether or not this Security be overdue, and neither the Company, the Trustee
      nor any such agent shall be affected by notice to the contrary.

     

    7.     SUCCESSOR
      OBLIGORS

     

    When
      a
      successor assumes all the obligations of its predecessor under the Securities
      of
      this series and the Indenture in accordance with the terms of the Indenture,
      the
      predecessor will be released from those obligations.

     

    8.     TRUSTEE
      DEALINGS WITH THE COMPANY

     

    The
      Trustee under the Indenture, in its individual or any other capacity, may become
      the owner or pledgee of Securities of this series and may otherwise deal with
      the Company, its Subsidiaries or their respective Affiliates as if it were
      not
      the Trustee.

     

    9.     NO
      RECOURSE AGAINST OTHERS

     

    No
      stockholder, director, officer, employee, incorporator or Affiliate of the
      Company shall have any liability for any obligation of the Company under the
      Securities of this series or the Indenture or for any claim based on, in respect
      of or by reason of, such obligations or their creation. Each Holder of the

    5. Investment
      Representations.
      In
      connection with the purchase of the Shares, Purchaser represents to the Company
      the following: 

     

    (a) The
      Company is a reporting company under the U.S. Securities Exchange Act, and
      its
      various periodic reports and other SEC filings are available for public
      inspection on the EDGAR system at www.sec.gov. Purchaser further acknowledges
      that Purchaser and Purchaser’s advisors have had the opportunity to ask
      questions of and receive answers from the Company’s management concerning this
      investment. Purchaser is aware of the Company’s business affairs and financial
      condition based on the said public available information and the answers from
      the Company’s management (the “Information”) and Purchaser and Purchaser’s
      advisors has evaluated the merits and risks of an investment in the Company
      and
      decided to acquire the Shares based on such Information. 

     

    (b) Purchaser
      understands that the Shares have not been registered under the U.S. Securities
      Act by reason of a specific exemption therefrom, which exemption depends upon,
      among other things, the bona fide nature of Purchaser’s investment intent as
      expressed herein.

     

     (c) Purchaser
      understands that the Shares are “restricted securities” within the meaning of
      applicable U.S. federal and state securities laws and that, pursuant to these
      laws, Purchaser must hold the Shares indefinitely unless they are registered
      with the U.S. Securities and Exchange Commission and qualified by state
      authorities, or an exemption from such registration and qualification
      requirements is available (e.g., Rule 144 or Regulation S). Purchaser further
      acknowledges that if an exemption from registration or qualification is
      available, it may be conditioned on various requirements including, but not
      limited to, the time and manner of sale, the holding period for the Shares,
      and
      requirements relating to the Company which are outside of the Purchaser’s
      control, and which the Company is under no obligation and may not be able to
      satisfy. 

     

    (d) Purchaser
      is an "accredited investor," as defined in US Securities Act Rule
      501. 

     

    (e) Purchaser
      has not entered into any agreement to pay commissions to any persons with
      respect to the purchase or sale of the Shares, except commissions for which
      Purchaser will be responsible. 

     

    (f) Purchaser
      understands and acknowledges that no Japanese, German or United States federal
      or state agency, governmental authority, regulatory body, stock exchange or
      other entity has made any finding or determination as to the merits of this
      investment, nor have any such agencies, governmental authorities, regulatory
      bodies, stock exchanges or other entities made any recommendation or endorsement
      with respect to the Shares. 

     

    (g) Purchaser,
      in evaluating the merits of an investment in the Shares, is not relying on
      the
      Company, its counsel, or any financial or other advisor to the Company for
      an
      evaluation of the tax, legal or other consequences of an investment in the
      Shares. 

     

    (h) Purchaser
      is purchasing the Shares for investment for its own account only and not with
      a
      view to, or for resale in connection with, any “distribution” thereof within the
      meaning of the U.S. Securities Act. 

     

    6. Legends.
      The
      certificates overlying the Shares shall bear the following legends:

     

    "The
      shares of common stock of Cytori Therapeutics, Inc. represented hereby have
      not
      been registered under the United States Securities Act of 1933, as amended
      (the
“Securities Act”). These securities may not be offered, sold, pledged or
      otherwise transferred (nor may exposure with respect to the shares otherwise
      be
      hedged) except (A)(1) in an offshore transaction complying with Rule 903 or
      Rule
      904 of Regulation S under the Securities Act, (2) pursuant to an exemption
      from
      registration under the Securities Act provided by Rule 144 thereunder (if
      available), or (3) pursuant to another valid exemption from registration under
      the Securities Act (if available), and (B) in each case in accordance with
      all
      applicable securities laws of the States of the United States. No representation
      can be made as to the availability of the exemption provided by Rule 144 under
      the Securities Act for resales of the shares. 

     

    

    This
      certificate evidences and entitles the holder hereof to certain rights as set
      forth in a Rights Agreement between Cytori Therapeutics, Inc. and Computershare
      Trust Company, Inc., a Colorado corporation, as Rights Agent, dated as of
      May

      amended (the "Rights Agreement"), the terms of which are hereby incorporated
      herein by reference and a copy of which is on file at the principal executive
      offices of Cytori Therapeutics, Inc. Under certain circumstances, as set forth
      in the Rights Agreement, such rights will be evidenced by separate certificates
      and will no longer be evidenced by this certificate. Cytori Therapeutics, Inc.
      will mail to the holder of this certificate a copy of the Rights Agreement
      without charge after receipt of a written request therefor. Under certain
      circumstances set forth in the Rights Agreement, rights issued to, or held
      by,

      Associate thereof (as defined in the Rights Agreement) and certain related
      Persons, whether currently held by or on behalf of such Person or by any
      subsequent holder, may become null and void."

     

    

     

    7. Registration.
      The
      Company shall within 30 business days after receipt of written request by
      Purchaser use reasonable efforts to, prepare and file with the US Securities
      and
      Exchange Commission (the "Commission")
      a
      Registration Statement covering the resale of the Shares for an offering to
      be
      made on a continuous basis pursuant to Rule 415. The Registration Statement
      shall be on Form S-3 (except if the Company is not then eligible to register
      for
      resale the Shares on Form S-3, in which case such registration shall be on
      another appropriate form in accordance with the US Securities Act and the rules
      promulgated thereunder). The Company shall use its reasonable efforts to cause
      the Registration Statement to be declared effective under the US Securities
      Act
      within 60 business days after such filing. The Company shall keep such
      Registration Statement continuously effective under the Securities Act for
      a
      period of two years (the “Effectiveness
      Period”).
      

     

    

     

    8. Registration

      Company shall: 

     

     (a) Furnish
      to the Purchaser a copy of the Registration Statement as proposed to be
      filed.

     

    (b) Prepare

      amendments, to the Registration Statement as may be necessary to keep the
      Registration Statement continuously effective as to the applicable Shares for
      the Effectiveness Period; (ii) cause the related Prospectus to be amended or
      supplemented by any required Prospectus supplement, and as so supplemented
      or

      any
      comments received from the Commission with respect to the Registration Statement
      or any amendment thereto and promptly provide the Purchaser true and complete
      copies of all correspondence from and to the Commission relating to the
      Registration Statement.

    

    (c) Notify
      the Purchaser (i)(A) when a Prospectus or any Prospectus supplement or
      post-effective amendment to the Registration Statement is proposed to be filed,
      (B) when the Commission notifies the Company whether there will be a “review” of
      such Registration Statement and whenever the Commission comments in writing
      on
      such Registration Statement, and (C) with respect to the Registration Statement
      or any post-effective amendment, when the same has become effective; (ii) of
      any
      request by the Commission or any other Federal or state governmental authority

      order suspending the effectiveness of the Registration Statement covering any
      or
      all of the Shares or the initiation of any proceedings for that purpose; (iv)
      of
      the receipt by the Company of any notification with respect to the suspension
      of
      the qualification or exemption from qualification of any of the Shares for
      sale
      in any State of the US, or the initiation or threatening of any proceeding
      for
      such purpose; and (v) of the occurrence of any event that makes any statement
      made in the Registration Statement or Prospectus or any document incorporated
      or
      deemed to be incorporated therein by reference untrue in any material respect
      or
      that requires any revisions to the Registration Statement, Prospectus or other
      documents so that, in the case of the Registration Statement or the Prospectus,
      as the case may be, it will not contain any untrue statement of a material
      fact
      or omit to state any material fact required to be stated therein or necessary
      to
      make the statements therein, in the light of the circumstances under which
      they
      were made, not misleading. 

    

     

    (d) Use
      its
      reasonable commercial efforts to avoid the issuance of, or, if issued, obtain
      the withdrawal of, (i) any order suspending the effectiveness of the
      Registration Statement, or (ii) any suspension of the qualification (or
      exemption from qualification) of any of the Shares for sale in any State of
      the
      US, at the earliest practicable moment.

    

     

    (e) If
      requested by the Purchaser, (i) promptly incorporate in a Prospectus supplement
      or post-effective amendment to the Registration Statement such information
      as
      the Company reasonably agrees should be included therein, and (ii) make all
      required filings of such Prospectus supplement or such post-effective amendment
      as soon as practicable after the Company has received notification of the
      matters to be incorporated in such Prospectus supplement or post-effective
      amendment.

    

     

    (f) Furnish
      to the Purchaser, without charge, at least one conformed copy of the
      Registration Statement and each amendment thereto, including financial
      statements and schedules, all documents incorporated or deemed to be
      incorporated therein by reference, and all exhibits to the extent requested
      by
      such Person (including those previously furnished or incorporated by reference)
      promptly after the filing of such documents with the Commission.

    

     

    (g) Promptly
      deliver to the Purchaser, without charge, as many copies of the Registration
      Statement, Prospectus or Prospectuses (including each form of prospectus) and
      each amendment or supplement thereto as Purchaser may reasonably request; and
      the Company hereby consents to the use of such Prospectus and each amendment
      or
      supplement thereto by the Purchaser in connection with the offering and sale
      of
      the Shares covered by such Prospectus and any amendment or supplement thereto.
      Should the Purchaser offer or sell the Shares, such Purchaser agrees to comply
      with all applicable securities laws.

            

     

    (h) Use
      its
      reasonable commercial efforts to register or qualify or cooperate with the
      selling Purchaser in connection with the registration or qualification (or
      exemption from such registration or qualification) of such Shares for offer
      and
      sale under the securities or Blue Sky laws of each State of the US as the
      Purchaser reasonably requests in writing, to keep each such registration or
      qualification (or exemption therefrom) effective during the Effectiveness Period
      and to do any and all other acts or things necessary or advisable to enable
      the
      disposition in such States of the Shares covered by a Registration Statement;
      provided,
      however,
      that
      the Company shall not be required to qualify generally to do business in any
      jurisdiction where it is not then so qualified or to take any action that would
      subject it to general service of process in any such jurisdiction where it
      is
      not then so subject or subject the Company to any tax in any such jurisdiction
      where it is not then so subject.

    

     

    (i) Upon
      the
      occurrence of any event contemplated by Section 8(c)(v), promptly prepare a
      supplement or amendment, including a post-effective amendment, to the
      Registration Statement or a supplement to the related Prospectus or any document
      incorporated or deemed to be incorporated therein by reference, and file any
      other required document so that, as thereafter delivered, neither the
      Registration Statement nor such Prospectus will contain an untrue statement
      of a
      material fact or omit to state a material fact required to be stated therein
      or
      necessary to make the statements therein, in the light of the circumstances
      under which they were made, not misleading.

    

     

    (j) Use
      its
      reasonable efforts to cause all Shares to be listed on any US national
      securities exchange (such as the NASDAQ Global Market), US quotation system,
      or
      US over-the-counter bulletin board, if any, on which the same securities issued
      by the Company are then listed.

    

     

    (k) If
      (i)
      there is material non-public information regarding the Company which the
      Company’s Board of Directors reasonably determines not to be in the Company’s
      best interest to disclose and which the Company is not otherwise required to
      disclose, or (ii) there is a significant business opportunity (including, but
      not limited to, the acquisition or disposition of assets (other than in the
      ordinary course of business) or any merger, consolidation, tender offer or
      other
      similar transaction) available to the Company which the Company’s Board of
      Directors reasonably determines not to be in the Company’s best interest to
      disclose and which the Company would be required to disclose under the
      Registration Statement, then the Company may suspend effectiveness of the
      Registration Statement and suspend the sale of Shares under the Registration
      Statement one time every three months or three times in any twelve month period,
      provided that the Company may not suspend its obligation for more than 60 days
      in the aggregate in any 12 month period.

    

     

    9. Registration

      In
      connection with the registration of the Shares, the Purchaser shall:

     

    (a) (i)
      not
      sell any Shares under the Registration Statement until it has received copies
      of
      the Prospectus as then amended or supplemented as contemplated in Section 8(g)
      and the notice from the Company that such Registration Statement and any
      post-effective amendments thereto have become effective as contemplated by
      Section 8(c), (ii) comply with the prospectus delivery requirements of the
      Securities Act as applicable to it in connection with sales of Shares pursuant

      receipt of a notice from the Company of the occurrence of any event of the
      kind
      described in Section 8(c)(ii), 8(c)(iii), 8(c)(iv), 8(c)(v) or 8(k), forthwith
      discontinue disposition of such Shares under the Registration Statement until
      the Purchaser’s receipt of the copies of the supplemented Prospectus and/or
      amended Registration Statement contemplated by Section 8(i), or until it is
      advised in writing by the Company that the use of the applicable Prospectus
      may
      be resumed, and, in either case, has received copies of any additional or
      supplemental filings that are incorporated or deemed to be incorporated by
      reference in such Prospectus or Registration Statement.

    

     

    10. Registration
      Expenses.

    

    All
      reasonable fees and expenses incident to the performance of or compliance with
      this Agreement by the Company shall be borne by the Company whether or not
      any
      Shares are sold pursuant to the Registration Statement. 

     

    

    11. Indemnification.

     

    (a) Indemnification
      by the Company.
      The
      Company shall indemnify and hold harmless Purchaser, its permitted assignees,
      officers, directors, agents, brokers, investment advisors and employees, each
      person who controls Purchaser or a permitted assignee (within the meaning of
      Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
      officers, directors, agents and employees of each such controlling person,
      and
      the respective successors, assigns, estate and personal representatives of
      each
      of the foregoing, to the fullest extent permitted by applicable law, from and
      against any and all claims, losses, damages, liabilities, penalties, judgments,
      costs (including, without limitation, costs of investigation) and expenses
      (including, without limitation, reasonable attorneys’ fees and expenses)
      (collectively, “Losses”),
      as
      incurred, arising out of or relating to any untrue or alleged untrue statement
      of a material fact contained in the Registration Statement, any Prospectus,
      as
      supplemented or amended, if applicable, or arising out of or relating to any
      omission or alleged omission of a material fact required to be stated therein
      or
      necessary to make the statements therein (in the case of any Prospectus or
      supplement thereto, in the light of the circumstances under which they were
      made) not misleading, except (i) to the extent, but only to the extent, that
      such untrue statements or omissions are based solely upon information regarding
      the Purchaser furnished in writing to the Company by the Purchaser expressly
      for
      use therein, or (ii) as a result of the failure of the Purchaser to deliver
      a
      Prospectus, as amended or supplemented, to a purchaser in connection with an
      offer or sale. The Company shall notify the Purchaser promptly of the
      institution, threat or assertion of any Proceeding of which the Company is
      aware
      in connection with the transactions contemplated by this Agreement. Such
      indemnity shall remain in full force and effect regardless of any investigation
      made by or on behalf of an Indemnified Party (as defined in Section
      11(3⁄4)
      hereof)
      and shall survive the transfer of the Shares by the Purchaser.

          

     

    (b) Conduct
      of Indemnification Proceedings.
      If any
      Proceeding shall be brought or asserted against any Person entitled to indemnity
      pursuant to Section 11(a) hereunder (an “Indemnified
      Party”),
      such
      Indemnified Party promptly shall notify the Person from whom indemnity is sought
      (the “Indemnifying
      Party)
      in
      writing, and the Indemnifying Party shall assume the defense thereof, including
      the employment of counsel reasonably satisfactory to the Indemnified Party
      and
      the payment of all fees and expenses incurred in connection with defense
      thereof; provided,
      that
      the failure of any Indemnified Party to give such notice shall not relieve
      the
      Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
      except (and only) to the extent that it shall be finally determined by a court
      of competent jurisdiction (which determination is not subject to appeal or
      further review) that such failure shall have materially and adversely prejudiced
      the Indemnifying Party.

          

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

     

    

    All
      reasonable fees and expenses of the Indemnified Party (including reasonable
      fees
      and expenses to the extent incurred in connection with investigating or
      preparing to defend such Proceeding in a manner not inconsistent with this
      Section) shall be paid to the Indemnified Party, as incurred, within 20 business
      days of written notice thereof to the Indemnifying Party (regardless of whether
      it is ultimately determined that an Indemnified Party is not entitled to
      indemnification hereunder; provided,
      that
      the Indemnifying Party may require such Indemnified Party to undertake to
      reimburse all such fees and expenses to the extent it is finally judicially
      determined that such Indemnified Party is not entitled to indemnification
      hereunder or pursuant to applicable law).

     

    

    (c) The
      indemnity agreement contained in this Section is in addition to any liability
      that the Indemnifying Parties may have to the Indemnified Parties.

     

    12. No
      Special Rights.
      Nothing
      in this Agreement shall affect in any manner whatsoever the right or power
      of
      the Company to negotiate, or to decline to negotiate, any contractual
      relationship with Purchaser, nor the right or power of Purchaser to negotiate,
      or to decline to negotiate, any contractual relationship with the
      Company.

     

    

    13. Miscellaneous. 

     

    (a) Governing
      Law.
      This
      Agreement and all acts and transactions pursuant hereto and the rights and
      obligations of the parties hereto shall be governed, construed and interpreted
      in accordance with the laws of the State of California, without giving effect
      to
      principles of conflicts of law. 

     

    

    (b) Entire
      Agreement; Enforcement of Rights.
      This
      Agreement sets forth the entire agreement and understanding of the parties
      relating to the subject matter herein and merges all prior discussions between
      them with regard to such subject matter. No modification of or amendment to
      this
      Agreement, nor any waiver of any rights under this Agreement, shall be effective
      unless in writing signed by the parties to this Agreement. The failure by either
      party to enforce any rights under this Agreement shall not be construed as
      a
      waiver of any rights of such party.

     

    

    (c) Construction.
      This
      Agreement is the result of negotiations between and has been reviewed by both
      of
      the parties hereto and their respective counsel, if any; accordingly, this
      Agreement shall be deemed to be the product of both of the parties hereto,
      and
      no ambiguity shall be construed in favor of or against either one of the parties
      hereto.

     

    

    (d) Notices.
      Any
      notice required or permitted by this Agreement shall be in writing and shall
      be
      deemed sufficient when delivered personally or sent and confirmed by fax or
      48
      hours after being deposited in the U.S. mail, as certified or registered mail,
      with postage prepaid, and addressed to the party to be notified at such party’s
      address or fax number as set forth below or as subsequently modified by written
      notice.

     

    

    (e) Counterparts.
      This
      Agreement may be executed in counterparts, each of which shall be deemed an
      original and all of which together shall constitute one instrument.
