      Senior Notes due 2014

    

    Capitalized
      terms used herein shall have the meanings assigned to them in the Indenture
      referred to below unless otherwise indicated.

    

    1.
       Interest.
      The
      Company promises to pay interest on the principal amount of this Note at 9.625%
      per annum from the date hereof until maturity and shall pay Additional Interest,
      if any, as provided in the Registration Rights Agreement, dated April 9, 2007
      referred below. The Company shall pay interest and Additional Interest, if
      any,
      semi-annually in arrears on May 1 and November 1 of each year, or if any such
      day is not a Business Day, on the next succeeding Business Day (each an
“Interest
      Payment Date”).
      Interest on the Notes shall accrue from the most recent date to which interest
      has been paid on the Notes (or one or more Predecessor Notes) or, if no interest
      has been paid, from November 1, 2006; provided
      that if
      there is no existing Default in the payment of interest, and if this Note is
      authenticated between a record date referred to on the face hereof and the
      next
      succeeding Interest Payment Date, interest shall accrue from such next
      succeeding Interest Payment Date; provided
      further
      that the first Interest Payment Date shall be May 1, 2007. The Company shall
      pay
      interest (including post-petition interest in any proceeding under any
      Bankruptcy Law) on overdue principal and premium, if any, from time to time
      on
      demand at a rate that is 1% per annum in excess of the rate then in effect;
      it
      shall pay interest (including post-petition interest in any proceeding under
      any
      Bankruptcy Law) on overdue installments of interest and Additional Interest
      (without regard to any applicable grace periods) from time to time on demand
      at
      the same rate to the extent lawful. Interest shall be computed on the basis
      of a
      360-day year of twelve 30-day months. If a payment date is not a Business Day,
      payment may be made on the next succeeding day that is a Business Day, and
      no
      interest shall accrue on such payment for the intervening period.

    

    2. 
      Method
      of Payment.
      The
      Company shall pay interest on the Notes (except defaulted interest and
      Additional Interest, if any) to the Persons in whose name this Note (or one
      or
      more Predecessor Notes) is registered at the close of business on the April
      15th
      or October 15th immediately preceding the Interest Payment Date, even if such
      Notes are canceled after such record date and on or before such Interest Payment
      Date, except as provided in Section 2.13 of the Indenture with respect to
      defaulted interest. The Company shall pay all Additional Interest, if any,
      on
      the dates of its choosing and in the amounts set forth in the Registration
      Rights Agreement. 
      The
      Notes shall be payable as to principal, premium, if any, and interest and
      Additional Interest, if any, at
      the
      office or agency of the Company maintained for such purpose, or, at the option
      of the Company, payment of interest and Additional Interest, if any, may
      be
      made by check mailed to the Holders at their addresses set forth in the register
      of Holders, and provided that payment by wire transfer of immediately available
      funds shall be required with respect to principal of and interest, premium,
      if
      any, on, all Global Notes and all other Notes the Holders of which shall have
      provided wire transfer instructions to the Company or the Paying Agent. Such
      payment shall be in such coin or currency of the United States of America as
      at
      the time of payment is legal tender for payment of public and private
      debts.

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    3. 
      Paying
      Agent and Registrar.
      Initially, Wells Fargo Bank, N.A., the Trustee under the Indenture, shall act
      as
      Paying Agent and Registrar. The Company may change any Paying Agent or Registrar
      without notice to any Holder. The Company or any of its Subsidiaries may act
      in
      any such capacity.

    

    4. 
      Indenture.
      The
      Company issued the Notes under an Indenture dated as of April 20, 2006 (the
      “Indenture”)
      among
      the Company, the Initial Guarantors and the Trustee. The terms of the Notes
      include those stated in the Indenture and those made part of the Indenture
      by
      reference to the Trust Indenture Act of 1939, as amended. The Notes are subject
      to all such terms, and Holders are referred to the Indenture and such Act for
      a
      statement of such terms. To the extent any provision of this Note conflicts
      with
      the express provisions of the Indenture, the provisions of the Indenture shall
      govern and be controlling. The Indenture pursuant to which this Note is issued
      provides that an unlimited amount of Additional Notes may be issued thereunder,
      subject to compliance with the covenants therein. 

    

    5. 
      Optional
      Redemption.
      (a) On
      or after May 1, 2010, the Company may redeem all or a portion of the Notes,

      due on an interest payment date), if redeemed during the twelve-month period

    (b)    In
      addition, at any time and from time to time prior to May 1, 2009, the Company
      may use the net proceeds of one or more Equity Offerings to redeem up to an
      aggregate of 35% of the aggregate principal amount of Notes issued under the
      Indenture (including the principal amount of any Additional Notes issued under
      the Indenture) at a redemption price equal to 109.625% of the aggregate
      principal amount of the Notes redeemed, plus accrued and unpaid interest, if
      any, to the redemption date (subject to the rights of holders of record on
      relevant record dates to receive interest due on an interest payment date);
      provided
      that
      this redemption provision shall not be applicable with respect to any
      transaction that results in a Change of Control. At least 65% of the aggregate
      principal amount of Notes (including the principal amount of any Additional
      Notes issued under the Indenture) must remain outstanding immediately after
      the
      occurrence of such redemption. In order to effect this redemption, the Company
      must mail a notice of redemption no later than 30 days after the closing of
      the
      related Equity Offering and must complete such redemption within 60 days of
      the
      closing of the Equity Offering.

      Mandatory
      Redemption.
      The
      Company shall not be required to make mandatory redemption or sinking fund
      payments with respect to the Notes.

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    7. 
      Repurchase
      at Option of Holders.
      

    

    (a)    Upon
      the
      occurrence of a Change of Control, each Holder may require the Company to
      purchase such Holder’s Notes in whole or in part in amounts of $1,000 or whole
      multiples of $1,000 in excess thereof, at a purchase price in cash in an amount
      equal to 101% of the principal amount thereof, plus accrued and unpaid interest,
      if any, to the date of purchase, pursuant to a Change of Control Offer in
      accordance with the procedures set forth in the Indenture.

    

    (b)    Under
      certain circumstances described in the Indenture, the Company will be required
      to apply the proceeds of Asset Sales to the repayment of the Notes and/or Pari
      Passu Indebtedness.

    

    8. 
      Selection
      and Notice of Redemption.
      If less
      than all of the Notes are to be redeemed or purchased in an offer to purchase
      at
      any time, the Trustee shall select the Notes to be redeemed or purchased among
      the Holders of the Notes not more than 60 days prior to the redemption date
      in
      compliance with the requirements of the principal national securities exchange,
      if any, on which the Notes are listed or, if the Notes are not so listed, on
      a
pro
      rata
      basis,
      by lot or in accordance with any other method the Trustee considers fair and
      reasonable. Redemptions pursuant to Section 3.07(b) of the Indenture shall
      be
      made on a pro
      rata
      basis or
      on as nearly a pro
      rata
      basis as
      practicable (subject to the provisions of the Depositary). In the event of
      partial redemption by lot, the particular Notes to be redeemed shall be
      selected, unless otherwise provided herein, not less than 30 nor more than
      60
      days prior to the redemption date by the Trustee from the outstanding Notes
      not
      previously called for redemption. Notices of redemption may not be conditional.
      If any Note is to be redeemed in part only, the notice of redemption that
      relates to that Note will state the portion of the principal amount thereof
      to
      be redeemed. A new Note in principal amount equal to the unredeemed portion
      of
      the original Note will be issued in the name of the Holder thereof upon
      cancellation of the original Note. Notes called for redemption become due on
      the

    12. 
      Defaults.
      In the
      case of an Event of Default arising from certain events of bankruptcy,
      insolvency or reorganization specified in the Inndenture, with respect to the
      Company or any Significant Subsidiary, all outstanding Notes will become due
      and
      payable immediately without further action or notice. If any other Event of
      Default occurs and is continuing, the Trustee or the Holders of at least 25%
      in
      principal amount of the then outstanding Notes may, and the Trustee at the
      request of such Holders shall, declare all unpaid principal of, premium, if
      any,
      and accrued interest on all Notes to be due and payable immediately, by a notice
      in writing to the Company (and to the Trustee if given by the Holders of the
      Notes) and upon any such declaration, such principal, premium, if any, and
      interest shall become due and payable immediately. The Trustee may withhold
      from
      Holders of the Notes notice of any continuing Default or Event of Default
      (except a Default or Event of Default relating to the payment of principal
      or
      interest) if it determines that withholding notice is in their interest. The
      Holders of not less than a majority in aggregate principal amount of the Notes
      outstanding by notice to the Trustee may on behalf of the Holders of all
      outstanding Notes waive any past Default and its consequences under the
      Indenture except a Default (1) in the payment of the principal of, premium,
      if
      any, or interest on any Note (which may only be waived with the consent of
      each
      Holder of Notes affected) or (2) in respect of a covenant or provision which
      under the Indenture cannot be modified or amended without the consent of the
      Holder of each Note affected by such modification or amendment. 

    

    13. 
      Trustee
      Dealings with the Company.
      The
      Trustee, in its individual or any other capacity, may make loans to, accept
      deposits from, and perform services for the Company or its Affiliates,
      and may otherwise deal with the Company or its Affiliates,
      as if it were not the Trustee.

    

    14. 
      No
      Recourse Against Others.
      No
      director, officer, employee, member or stockholder of the Company or any
      Restricted Subsidiary, as such, will have any liability for any obligations
      of
      the Company or the Restricted Subsidiaries under the Notes, the Indenture or
      the
      Guarantees to which they are a party, or for any claim based on, in respect
      of,
      or by reason of, such obligations or their creation. Each Holder of Notes by
      accepting a Note waives and releases all such liability. The waiver and release
      are part of the consideration for issuance of the Notes. The waiver may not
      be
      effective to waive liabilities under the federal securities laws.

    

    15. 
      Authentication.

      Note shall not be valid until authenticated by the manual signature of the

      Additional
      Rights of Holders of Restricted Global Notes and Restricted Definitive
      Notes.

      Restricted Global Notes and Restricted Definitive Notes issued on the Issue

      shall have all the rights set forth in the Registration Rights Agreement dated

    17. 
      CUSIP
      Numbers.
      Pursuant to a recommendation promulgated by the Committee on Uniform Security
      Identification Procedures, the Company has caused CUSIP numbers to be printed
      on
      the Notes and the Trustee may use CUSIP numbers in notices of redemption as a
      convenience to Holders. No representation is made as to the accuracy of such
      numbers either as printed on the Notes or as contained in any notice of
      redemption and reliance may be placed only on the other identification numbers
      placed thereon.

      9
5⁄8%
        Senior Notes due 2014

      

      Capitalized
        terms used herein shall have the meanings assigned to them in the Indenture
        referred to below unless otherwise indicated.

      

      1. 
        Interest.
        The
        Company promises to pay interest on the principal amount of this Note at
        9.625%
        per annum from the date hereof until maturity and shall pay Additional Interest,
        if any, as provided in the Registration Rights Agreement, dated April 9,
        2007
        referred below. The Company shall pay interest and Additional Interest, if
        any,
        semi-annually in arrears on May 1 and November 1 of each year, or if any
        such
        day is not a Business Day, on the next succeeding Business Day (each an
“Interest
        Payment Date”).
        Interest on the Notes shall accrue from the most recent date to which interest
        has been paid on the Notes (or one or more Predecessor Notes) or, if no interest
        has been paid, from November 1, 2006; provided
        that if
        there is no existing Default in the payment of interest, and if this Note
        is
        authenticated between a record date referred to on the face hereof and the
        next
        succeeding Interest Payment Date, interest shall accrue from such next
        succeeding Interest Payment Date; provided
        further
        that the first Interest Payment Date shall be May 1, 2007. The Company shall
        pay
        interest (including post-petition interest in any proceeding under any
        Bankruptcy Law) on overdue principal and premium, if any, from time to time
        on
        demand at a rate that is 1% per annum in excess of the rate then in effect;
        it
        shall pay interest (including post-petition interest in any proceeding under
        any
        Bankruptcy Law) on overdue installments of interest and Additional Interest
        (without regard to any applicable grace periods) from time to time on demand
        at
        the same rate to the extent lawful. Interest shall be computed on the basis
        of a
        360-day year of twelve 30-day months. If a payment date is not a Business
        Day,
        payment may be made on the next succeeding day that is a Business Day, and
        no
        interest shall accrue on such payment for the intervening period.

      

      2. 
        Method
        of Payment.
        The
        Company shall pay interest on the Notes (except defaulted interest and
        Additional Interest, if any) to the Persons in whose name this Note (or one
        or
        more Predecessor Notes) is registered at the close of business on the April
        15th
        or October 15th immediately preceding the Interest Payment Date, even if
        such
        Notes are canceled after such record date and on or before such Interest
        Payment
        Date, except as provided in Section 2.13 of the Indenture with respect to
        defaulted interest. The Company shall pay all Additional Interest, if any,
        on
        the dates of its choosing and in the amounts set forth in the Registration
        Rights Agreement. 
        The
        Notes shall be payable as to principal, premium, if any, and interest and
        Additional Interest, if any, at
        the
        office or agency of the Company maintained for such purpose, or, at the option
        of the Company, payment of interest and Additional Interest, if any, may
        be
        made by check mailed to the Holders at their addresses set forth in the register
        of Holders, and provided that payment by wire transfer of immediately available
        funds shall be required with respect to principal of and interest, premium,
        if
        any, on, all Global Notes and all other Notes the Holders of which shall
        have
        provided wire transfer instructions to the Company or the Paying Agent. Such
        payment shall be in such coin or currency of the United States of America
        as at
        the time of payment is legal tender for payment of public and private
        debts.

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      3. 
        Paying
        Agent and Registrar.
        Initially, Wells Fargo Bank, N.A., the Trustee under the Indenture, shall
        act as
        Paying Agent and Registrar. The Company may change any Paying Agent or Registrar
        without notice to any Holder. The Company or any of its Subsidiaries may
        act in
        any such capacity.

      

      4. 
        Indenture.
        The
        Company issued the Notes under an Indenture dated as of April 20, 2006 (the
        “Indenture”)
        among
        the Company, the Initial Guarantors and the Trustee. The terms of the Notes
        include those stated in the Indenture and those made part of the Indenture
        by
        reference to the Trust Indenture Act of 1939, as amended. The Notes are subject
        to all such terms, and Holders are referred to the Indenture and such Act
        for a
        statement of such terms. To the extent any provision of this Note conflicts
        with
        the express provisions of the Indenture, the provisions of the Indenture
        shall
        govern and be controlling. The Indenture pursuant to which this Note is issued
        provides that an unlimited amount of Additional Notes may be issued thereunder,
        subject to compliance with the covenants therein. 

      

      5. 
        Optional
        Redemption.
        (a) On
        or after May 1, 2010, the Company may redeem all or a portion of the Notes,
        on
        not less than 30 nor more than 60 days’ prior notice, in amounts of $1,000 or
        whole multiples of $1,000 in excess thereof at the following redemption prices
        (expressed as percentages of the principal amount), set forth below plus
        accrued
        and unpaid interest, if any, thereon, to the applicable redemption date (subject
        to the rights of holders of record on relevant record dates to receive interest
        due on an interest payment date), if redeemed during the twelve-month period
        beginning on May 1 of the years indicated below:

      

      
        	
                Year

              	 	
                Redemption
                  Price

                100.000%

              

      

      

      (b)    In
        addition, at any time and from time to time prior to May 1, 2009, the Company
        may use the net proceeds of one or more Equity Offerings to redeem up to
        an
        aggregate of 35% of the aggregate principal amount of Notes issued under
        the
        Indenture (including the principal amount of any Additional Notes issued
        under
        the Indenture) at a redemption price equal to 109.625% of the aggregate
        principal amount of the Notes redeemed, plus accrued and unpaid interest,
        if
        any, to the redemption date (subject to the rights of holders of record on
        relevant record dates to receive interest due on an interest payment date);
        provided
        that
        this redemption provision shall not be applicable with respect to any
        transaction that results in a Change of Control. At least 65% of the aggregate
        principal amount of Notes (including the principal amount of any Additional
        Notes issued under the Indenture) must remain outstanding immediately after
        the
        occurrence of such redemption. In order to effect this redemption, the Company
        must mail a notice of redemption no later than 30 days after the closing
        of the
        related Equity Offering and must complete such redemption within 60 days
        of the
        closing of the Equity Offering.

      

      6. 
        Mandatory
        Redemption.
        The
        Company shall not be required to make mandatory redemption or sinking fund
        payments with respect to the Notes.

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      7. 
        Repurchase
        at Option of Holders.
        

      

      (a)    Upon
        the
        occurrence of a Change of Control, each Holder may require the Company to
        purchase such Holder’s Notes in whole or in part in amounts of $1,000 or whole
        multiples of $1,000 in excess thereof, at a purchase price in cash in an
        amount
        equal to 101% of the principal amount thereof, plus accrued and unpaid interest,
        if any, to the date of purchase, pursuant to a Change of Control Offer in
        accordance with the procedures set forth in the Indenture.

      

      (b)    Under
        certain circumstances described in the Indenture, the Company will be required
        to apply the proceeds of Asset Sales to the repayment of the Notes and/or
        Pari
        Passu Indebtedness.

      

      8. 
        Selection
        and Notice of Redemption.
        If less
        than all of the Notes are to be redeemed or purchased in an offer to purchase
        at
        any time, the Trustee shall select the Notes to be redeemed or purchased
        among
        the Holders of the Notes not more than 60 days prior to the redemption date
        in
        compliance with the requirements of the principal national securities exchange,
        if any, on which the Notes are listed or, if the Notes are not so listed,
        on a
pro
        rata
        basis,
        by lot or in accordance with any other method the Trustee considers fair
        and
        reasonable. Redemptions pursuant to Section 3.07(b) of the Indenture shall
        be
        made on a pro
        rata
        basis or
        on as nearly a pro
        rata
        basis as
        practicable (subject to the provisions of the Depositary). In the event of
        partial redemption by lot, the particular Notes to be redeemed shall be
        selected, unless otherwise provided herein, not less than 30 nor more than
        60
        days prior to the redemption date by the Trustee from the outstanding Notes
        not
        previously called for redemption. Notices of redemption may not be conditional.
        If any Note is to be redeemed in part only, the notice of redemption that
        relates to that Note will state the portion of the principal amount thereof
        to
        be redeemed. A new Note in principal amount equal to the unredeemed portion
        of
        the original Note will be issued in the name of the Holder thereof upon
        cancellation of the original Note. Notes called for redemption become due
        on the
        date fixed for redemption. On and after the redemption date, interest and
        Addditional Interest, if any, shall cease to accrue on Notes or portions
        of them
        called for redemption.

      

      9. 
        Denominations,
        Transfer, Exchange.
        The
        Notes are in registered form without coupons in denominations of $1,000 and
        whole multiples of $1,000 in excess thereof. The transfer of Notes may be
        registered and Notes may be exchanged as provided in the Indenture. The
        Registrar and the Trustee may require a Holder, among other things, to furnish
        appropriate endorsements and transfer documents and the Company may require
        a
        Holder to pay any taxes and fees required by law or permitted by the Indenture.
        The Company is not required to transfer or exchange any Note selected for
        redemption. Also, the Company is not required to transfer or exchange any
        Note
        for a period of 15 days before a selection of Notes to be redeemed.

      

      10. 
        Persons
        Deemed Owners.
        The
        registered Holder of a Note will be treated as its owner for all
        purposes.

      

      11. 
        Amendment,
        Supplement and Waiver.
        The
        Indenture or the Notes may be amended or supplemented only as provided in
        the
        Indenture.

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      12. 
        Defaults.
        In the
        case of an Event of Default arising from certain events of bankruptcy,
        insolvency or reorganization specified in the Inndenture, with respect to
        the
        Company or any Significant Subsidiary, all outstanding Notes will become
        due and
        payable immediately without further action or notice. If any other Event
        of
        Default occurs and is continuing, the Trustee or the Holders of at least
        25% in
        principal amount of the then outstanding Notes may, and the Trustee at the
        request of such Holders shall, declare all unpaid principal of, premium,
        if any,
        and accrued interest on all Notes to be due and payable immediately, by a
        notice
        in writing to the Company (and to the Trustee if given by the Holders of
        the
        Notes) and upon any such declaration, such principal, premium, if any, and
        interest shall become due and payable immediately. The Trustee may withhold
        from
        Holders of the Notes notice of any continuing Default or Event of Default
        (except a Default or Event of Default relating to the payment of principal
        or
        interest) if it determines that withholding notice is in their interest.
        The
        Holders of not less than a majority in aggregate principal amount of the
        Notes
        outstanding by notice to the Trustee may on behalf of the Holders of all
        outstanding Notes waive any past Default and its consequences under the
        Indenture except a Default (1) in the payment of the principal of, premium,
        if
        any, or interest on any Note (which may only be waived with the consent of
        each
        Holder of Notes affected) or (2) in respect of a covenant or provision which
        under the Indenture cannot be modified or amended without the consent of
        the
        Holder of each Note affected by such modification or amendment.

      

      13. 
        Trustee
        Dealings with the Company.
        The
        Trustee, in its individual or any other capacity, may make loans to, accept
        deposits from, and perform services for the Company or its Affiliates,
        and may otherwise deal with the Company or its Affiliates,
        as if it were not the Trustee.

      

      14. 
        No
        Recourse Against Others.
        No
        director, officer, employee, member or stockholder of the Company or any
        Restricted Subsidiary, as such, will have any liability for any obligations
        of
        the Company or the Restricted Subsidiaries under the Notes, the Indenture
        or the
        Guarantees to which they are a party, or for any claim based on, in respect
        of,
        or by reason of, such obligations or their creation. Each Holder of Notes
        by
        accepting a Note waives and releases all such liability. The waiver and release
        are part of the consideration for issuance of the Notes. The waiver may not
        be
        effective to waive liabilities under the federal securities laws.

      

      15. 
        Authentication.
        This
        Note shall not be valid until authenticated by the manual signature of the
        Trustee or an authenticating agent.

        Restricted Global Notes and Restricted Definitive Notes issued on the Issue
        Date
        shall have all the rights set forth in the Registration Rights Agreement
        dated

      17. 
        CUSIP
        Numbers.
        Pursuant to a recommendation promulgated by the Committee on Uniform Security
        Identification Procedures, the Company has caused CUSIP numbers to be printed
        on
        the Notes and the Trustee may use CUSIP numbers in notices of redemption
        as a
        convenience to Holders. No representation is made as to the accuracy of such
        numbers either as printed on the Notes or as contained in any notice of
        redemption and reliance may be placed only on the other identification numbers
        placed thereon.
