    (b) Form
      of Certificated Notes.
      The
      Senior Notes and the Trustee’s certificate of authentication, other than those
      issued in global form, shall be substantially in the form of Exhibit
      A
      hereto,
      the terms of which are hereby incorporated in and expressly made a part of
      this
      Indenture. The Senior Notes may have notations, legends or endorsements required
      by law, stock exchange rule or usage in addition to those set forth on
Exhibit

      Each

      provisions contained in the Senior Notes shall constitute, and are hereby
      expressly made, a part of this Indenture, and the Company, the Guarantors and
      the Trustee, by their execution and delivery of this Indenture, expressly agree
      to such terms and provisions and to be bound thereby. To the extent any
      provision of any Senior Note conflicts with the express provisions of this
      Indenture, the provisions of the Indenture shall govern and be

    (c) Form
      of Global Notes.
      Senior
      Notes issued in global form shall be substantially in the form of Exhibit
      A
      attached
      hereto (but including the Global Note Legend thereon and the “Schedule of
      Exchanges of Interests in the Global Note” attached as Exhibit
      B
      hereto).
      Each Global Note shall represent such aggregate principal amount of the
      outstanding Senior Notes as shall be specified therein, and each shall provide
      that it shall represent the aggregate principal amount of outstanding Senior
      Notes from time to time endorsed thereon and that the aggregate principal amount
      of outstanding Senior Notes represented thereby may from time to time be reduced
      or increased, as appropriate, to reflect exchanges and redemptions thereof
      and
      transfers of interests therein. Any endorsement of a Global Note to reflect
      the
      amount of any increase or decrease in the aggregate principal amount of
      outstanding Senior Notes represented thereby shall be made by the Trustee or
      the
      Custodian, at the direction of the Trustee, in accordance with instructions
      given by the Holder thereof as required by Section
      2.06
      hereof.

     

    (d) Book-entry
      Provisions.
      This
Section
      2.01(d)
      shall
      apply only to Global Notes deposited with the Trustee, as custodian for the
      Depository. Members of, or participants in, the Depository (“Agent
      Members”)
      shall
      have no rights under this Indenture with respect to any Global Note held on
      their behalf by the Depository, or the Trustee as its custodian, or under the
      Global Note, and the Depository or its nominee, as the case may be, may be
      treated by the Company, the Trustee and any agent of the Company or the Trustee
      as the absolute owner of the Global Note for all purposes whatsoever.
      Notwithstanding the foregoing, nothing herein shall prevent the Company, the
      Trustee or any agent of the Company or the Trustee from giving effect to any
      written certification, proxy or other authorization furnished by the Depository
      or impair, as between the Depository and its Agent Members, the operation of
      customary practices governing the exercise of the rights of a holder of any
      Senior Note.

     

    (e) Certificated
      Securities.

     

    (i) The
      Company shall issue Certificated Notes to all owners of beneficial interests
      in
      Global Notes if: (1) at any time the Depository notifies the Company that it
      is
      unwilling or unable to continue to act as Depository for the Global Notes or
      if
      at any time the Depository shall no longer be eligible to act as such because
      it
      ceases to be a properly-registered clearing agency, and, in either case, the
      Company shall not have appointed a successor Depository within 120 days after
      the Company receives such notice or becomes aware of such ineligibility or
      (2)
      the Company, at its option, determines that the Global Notes shall be exchanged
      for Certificated Notes and delivers a written notice to such effect to the
      Trustee. Upon the occurrence of any of the events set forth in clauses (1)
      or
      (2) above, the Company shall execute, and, upon receipt of an Authentication
      Order in accordance with Section
      2.02
      hereof,
      the Trustee shall authenticate and deliver, Certificated Notes, in authorized
      denominations, in an aggregate principal amount equal to the principal amount
      of
      the Global Notes in exchange for such Global Notes. Upon the exchange of a
      Global Note for Certificated Notes, such Global Note shall be cancelled by
      the
      Trustee or an agent of the Company or the Trustee.

    (ii) The
      Company shall issue Certificated Notes to a Holder of, or an owner of a
      beneficial interest in, a Global Note in exchange for such Global Note or
      beneficial interest, as the case may be, upon written request from Holders
      (or
      owners of beneficial interests) representing 25% or more of the then outstanding
      principal amount of the Senior Notes, if a Default or Event of Default shall
      have occurred and be continuing. Upon the occurrence of the foregoing, the
      Company shall execute, and, upon receipt of an Authentication Order in
      accordance with Section
      2.02
      hereof,
      the Trustee shall authenticate and deliver, Certificated Notes, in authorized
      denominations, in an aggregate principal amount equal to the principal amount
      of
      the Global Note owned by such Holder or such owner of a beneficial interest.
      Upon the exchange of all or a portion of a Global Note for Certificated Notes,
      such Global Note shall be cancelled or correspondingly reduced by the Trustee
      or
      an agent of the Company or the Trustee. In the event that the Certificated
      Notes
      are not issued to an owner of a beneficial interest in a Global Note promptly
      after the Company has received a request from such owner, the Company expressly
      acknowledges, with respect to the right of any Holder to pursue a remedy
      pursuant to this Indenture, the right of any such owner to pursue such remedy
      with respect to the portion of the Global Note that represents such owner’s
      beneficial interest as if such Certificated Notes had been issued. 

     

    (iii) Certificated
      Notes issued in exchange for a Global Note pursuant to this Section
      2.01
      shall be
      registered in such names and in such authorized denominations as the Depository,
      pursuant to instructions from its Agent Members or its Applicable Procedures,
      shall instruct the Trustee or an agent of the Company or the Trustee in writing.
      The Trustee or such agent shall deliver such Certificated Notes to or as
      directed by the Persons in whose names such Certificated Notes are so registered
      or to the Depository.

                and Authentication.

            


    

     

    (a) A
      duly
      authorized Officer of the Company shall sign the Senior Notes for the Company
      by
      manual or facsimile signature. 

     

    (b) If
      an
      Officer whose signature is on a Senior Note no longer holds that office at
      the
      time a Senior Note is authenticated, the Senior Note shall nevertheless be
      valid. In addition, if a Person is not an Officer at the time a Senior Note
      is
      authenticated, but becomes an Officer on or prior to the delivery of the Senior
      Note, the Senior Note shall nevertheless be valid.

    (c) A
      Senior
      Note shall not be valid until authenticated by the manual signature of an
      authorized signatory of the Trustee. The signature of the Trustee shall be
      conclusive evidence that the Senior Note has been authenticated under this
      Indenture.

     

    (d) The
      Trustee shall, upon a written order of the Company signed by an Officer of
      the
      Company (an “Authentication
      Order”),
      authenticate and deliver the Senior Notes for issuance. 

     

    (e) The
      Trustee may appoint an authenticating agent acceptable to the Company to
      authenticate Senior Notes. Unless limited by the terms of such appointment,
      an
      authenticating agent may authenticate Senior Notes whenever the Trustee may
      do
      so. Each reference in this Indenture to authentication by the Trustee includes
      authentication by such agent. An authenticating agent has the same rights as
      an
      Agent to deal with the Holders, the Company or an Affiliate of the

    (a) The
      Company shall maintain an office or agency (which may be an office of the
      Trustee or an affiliate of the Trustee, registrar or co-registrar) where Senior
      Notes may be presented for registration of transfer or for exchange
      (“Registrar”),
      an

      Agent”)
      and an
      office or agency where notices and demands to or upon the Company in respect
      of
      the Senior Notes and this Indenture may be served. The Registrar shall keep
      a
      register of the Senior Notes and of their transfer and exchange. The Company
      may
      appoint one or more co-registrars and one or more additional paying agents.
      The
      term “Registrar”
      includes any co-registrar and the term “Paying
      Agent”
      includes any additional paying agent. The Company may change any Paying Agent
      or
      Registrar without notice to any Holder. The Company shall notify the Trustee
      and
      the Trustee shall notify the Holders of the Senior Notes in writing of the
      name
      and address of any Agent not a party to this Indenture. The Company or any
      of
      its Restricted Subsidiaries may act as Paying Agent or Registrar. The Company
      shall enter into an appropriate agency agreement with any Registrar or Paying
      Agent not a party to this Indenture. The agreement shall implement the
      provisions of this Indenture that relate to such agent. The Company shall notify
      the Trustee of the name and address of any such agent. If the Company fails
      to
      maintain a Registrar or Paying Agent, or fails to give the foregoing notice,
      the
      Trustee shall act as such, and shall be entitled to appropriate compensation
      in
      accordance with Section 8.07
      hereof.

     

    (b) The
      Company initially appoints DTC to act as Depository with respect to the Global

    The
      Company shall require each Paying Agent other than the Trustee to agree in
      writing that the Paying Agent shall hold in trust for the benefit of Holders
      or
      the Trustee all money held by the Paying Agent for the payment of principal
      or
      interest on the Senior Notes, and shall notify the Trustee of any default by
      the
      Company in making any such payment. While any such default continues, the
      Trustee may require a Paying Agent to pay all funds held by it to the Trustee.
      The Company at any time may require a Paying Agent to pay all funds held by
      it
      to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other
      than the Company or a Restricted Subsidiary) shall have no further liability
      for
      such funds. If the Company or a Restricted Subsidiary acts as Paying Agent,
      it
      shall segregate and hold in a separate trust fund for the benefit of the Holders
      all funds held by it as Paying Agent. Upon the occurrence, and during the
      continuation, of any Event of Default, the Trustee shall serve as Paying Agent
      and Registrar for the Senior Notes.

    (a) Transfer
      and Exchange of Global Notes.
      A
      Global Note may not be transferred as a whole except by the Depository to a
      nominee of the Depository, by a nominee of the Depository to the Depository
      or
      to another nominee of the Depository, or by the Depository or any such nominee
      to a successor Depository or a nominee of such successor Depository. All Global
      Notes will be exchanged by the Company for Certificated Notes if (1) the Company
      delivers to the Trustee notice from the Depository that it is unwilling or
      unable to continue to act as Depository or that it is no longer a
      properly-registered clearing agency and, in either case, a successor Depository
      is not appointed by the Company within 120 days after the date of such notice
      from the Depository or (2) the Company in its sole discretion determines that
      the Global Notes (in whole but not in part) should be exchanged for Certificated
      Notes and delivers a written notice to such effect to the Trustee. Upon the
      occurrence of any of the preceding events in (1) or (2) above, Certificated
      Notes shall be issued in such names as the Depository shall instruct the
      Trustee. Global Notes also may be exchanged or replaced, in whole or in part,
      as
      provided in Sections
      2.07
      and
Section
      2.10
      hereof.
      Every Senior Note authenticated and delivered in exchange for, or in lieu of,
      a
      Global Note or any portion thereof, pursuant to this Section
      2.06
      or
Sections
      2.07
      or
Section
      2.10
      hereof,
      shall be authenticated and delivered in the form of, and shall be, a Global
      Note. A Global Note may not be exchanged for another Senior Note other than
      as
      provided in this Section
      2.06(a),
      however, beneficial interests in a Global Note may be transferred and exchanged
      as provided in Section
      2.06(b)
      or
(c)
      hereof.
      Neither the Company nor the Trustee will be liable for any delay by a Holder
      of
      a Global Note or the Depository in identifying the beneficial owners of Senior
      Notes, except as a result of the Company’s or Trustee’s own grossly negligent
      action, grossly negligent failure to act or own willful misconduct, as the
      case
      may be. In the absence of bad faith on their part, the Company and the Trustee
      may conclusively rely on, and will be protected in relying on written
      instructions from the Holder of a Global Note or the Depository for all purposes
      under this Indenture. 

     

    (b) Transfer
      and Exchange of Beneficial Interests in the Global Notes.
      The
      transfer and exchange of beneficial interests in the Global Notes shall be
      effected through the Depository, in accordance with the provisions of this
      Indenture and the Applicable Procedures. Beneficial interests in Global Notes
      may be subject to restrictions on transfer to the extent required by the
      Securities Act. Beneficial interests in any Global Note may be transferred
      to
      Persons who take delivery thereof in the form of a beneficial interest in a
      Global Note, in accordance with the Applicable Procedures. No written orders
      or
      instructions shall be required to be delivered to the Registrar to effect the
      transfers described in this Section
      2.06(b).
      

     

    (c) Transfer
      or Exchange of Beneficial Interests for Certificated Notes. The
      holder of a beneficial interest in a Global Note may exchange such beneficial
      interest for a Certificated Note or transfer such beneficial interest to a
      Person who takes delivery thereof in the form of a Certificated Note only in
      the
      circumstances specified in Section
      2.01(e),
      in
      which event such owner of such beneficial interest shall instruct the Depository
      (or shall cause the appropriate participant to direct the Depository) in
      accordance with the Applicable Procedures to instruct the Trustee to reduce
      the
      aggregate principal amount of the Global Note by the applicable amount of such
      exchange or transfer and to issue in exchange therefore a Certificated Note
      or
      Senior Notes in such aggregate amount and registered as provided in such
      instruction; and upon the Trustee’s receipt of such instruction from the
      Depository (or from the applicable Agent Member or beneficial owner pursuant
      to
      the Depository’s proxy procedures), the Trustee to, and the Trustee shall, cause
      the aggregate principal amount of the applicable Global Note to be reduced
      accordingly pursuant to Section
      2.06(g)
      hereof,
      and the Company shall execute and the Trustee shall authenticate and deliver,
      in
      both cases in accordance with Section
      2.02
      hereof,
      to the Person designated in such instruction a Certificated Note in the
      appropriate principal amount. Any Certificated Note issued in exchange for
      a
      beneficial interest pursuant to this Section
      2.06(c)
      shall be
      registered in such name or names and in such authorized denomination or
      denominations as the holder of such beneficial interest shall instruct the
      Registrar through instructions from the Depository and the Agent Member. The
      Trustee shall mail or deliver such Certificated Notes to the Persons in whose
      names such Senior Notes are so registered.

      Holder of a Certificated Note may exchange such Senior Note for a beneficial
      interest in a Global Note or transfer such Certificated Notes to a Person who
      takes delivery thereof in the form of a beneficial interest in a Global Note
      at
      any time. Upon receipt of a request for such an exchange or transfer together
      with surrender of the Certificated Note to be exchanged or transferred, (and,
      accompanied by a written instrument or instruments of transfer as provided
      in
Section
      2.06(e)
      hereof,
      and subject to the Applicable Procedures), the Trustee shall cancel the
      applicable Certificated Note and increase or cause to be increased the aggregate
      principal amount of one of the Global Notes pursuant to Section
      2.06(g)
      hereof.


     

    (e) Transfer
      and Exchange of Certificated Notes for Certificated Notes.
      Upon
      request by a Holder of Certificated Notes and such Holder’s compliance with the
      provisions of this Section
      2.06(e),
      the
      Registrar shall register the transfer or exchange of Certificated Notes. Prior
      to such registration of transfer or exchange, the requesting Holder shall
      present or surrender to the Registrar the Certificated Notes duly endorsed
      or
      accompanied by a written instruction of transfer in form satisfactory to the
      Registrar duly executed by such Holder or by its attorney, duly authorized

      writing. In addition, the requesting Holder must provide any additional
      certifications, documents and information, as applicable, required pursuant
      to

    Notwithstanding
      anything contained herein to the contrary, the Senior Notes and interests
      therein may not be issued, sold or transferred to any Holder other than the
      initial Holder, unless (i) the initial Holder and any subsequent Holder shall
      have delivered to Trustee evidence satisfactory to Trustee that the transferee
      is a Qualified Institutional Buyer, as such term is defined under Rule 144A
      promulgated pursuant to the Securities Act of 1933, as long as such rule is
      applicable, and otherwise in accordance with federal and state securities laws
      applicable at such time, and (ii) Trustee obtained a signed Investor Letter
      in the same form as attached to the Indenture as Exhibit
      G
      and attached to the Notes, or an opinion of Special Counsel that such Investor
      Letter is no longer required. The senior Notes shall bear legends stating that
      they are subject to the transfer restrictions described in this
      Section 2.06 of the Indenture. By purchasing a Note, the initial Holder and
      any subsequent Holder shall be deemed to have agreed to the transfer
      requirements contained in this Section 2.06.

      the
      Trustee’s requirements are met. If required by the Trustee or the Company, an
      indemnity bond must be supplied by the Holder that is sufficient in the judgment
      of the Trustee and the Company to protect the Company, the Trustee, any Agent
      and any authenticating agent from any loss that any of them may suffer if a
      Senior Note is replaced. The Company may charge for its expenses in replacing

      Senior Notes outstanding at any time shall be the entire principal amount of

      authenticated by the Trustee except for those cancelled by it, those delivered
      to it for cancellation and those described in this Section

      as not
      outstanding. Except as set forth in
      Section 2.09
      hereof,
      a Senior Note does not cease to be outstanding because the Company or an
      Affiliate of the Company holds the Senior Note; provided,
      however,
      that
      Senior Notes held by the Company or a Subsidiary of the Company shall be deemed
      not to be outstanding for purposes of Section

    (b) If
      a
      Senior Note is replaced pursuant to Section

      hereof,
      it ceases to be outstanding unless the Trustee receives proof satisfactory
      to it
      that the replaced Senior Note is held by a bona fide purchaser.

     

    (c) If
      the
      principal amount of any Senior Note is considered paid under Section

      it ceases to be outstanding and interest on it ceases to accrue.

    (a) Except
      as
      set forth in Section
      3.10

      the Senior Notes will not be redeemable at the Company’s option prior to April

      than
      60 days’ notice to the Holders, at 100% of the principal amount plus accrued and
      unpaid interest thereon to the applicable redemption date.

     

    (b) Any
      redemption pursuant to this Section
      3.07
      shall be
      made pursuant to the provisions of Sections

    The
      Company shall not be required to make mandatory redemption or sinking fund
      payments with respect to the Senior Notes, except as required pursuant to

                to Purchase with Excess revenue;
                Mandatory Redemption FROM Excess
                Revenue.

            


    

     

    (a) The
      Trustee shall establish and maintain within the Senior Note Fund (as described
      in Sections 5.01 and 5.02) the Excess Revenue Account. The Excess Revenue
      Account shall be established and maintained so as to create, perfect and
      establish the priority of the security interest of the Trustee in such account
      and all cash, Permitted Investments and other property from time to time
      deposited therein and otherwise to effectuate the lien of the Senior
      Notes.

     

    (b) The
      Trustee shall have sole dominion and control over the Excess Revenue Account
      (including, inter alia, the sole power to direct withdrawals or transfers from
      the Excess Revenue Account and to direct the investment and reinvestment of
      funds in the Excess Revenue Account, subject to the provisions of this
Section 3.09).
      The
      Trustee shall make withdrawals and transfers from the Excess Revenue Account
      in
      accordance with the terms of this Indenture. The Company and the Trustee
      acknowledge that the Excess Revenue Account is a “deposit account” or
“investment property” within the meaning of Section 9-102 of the UCC and that
      the Trustee has “control,” for purposes of Section 9-315 of the UCC, of the
      Excess Revenue Account.

     

    (c) The
      Trustee shall establish and maintain the Excess Revenue Account on the date
      of
      this Indenture, and the Excess Revenue Account shall bear a designation clearly
      indicating that the funds deposited therein are held for the benefit of the
      Senior Note holders. Except as expressly provided herein, all Excess Revenue
      attributable
      to the Senior Notes shall
      be
      deposited in the Excess Revenue Account and transferred therefrom in accordance
      with the terms of this Indenture. No funds shall be deposited in the Excess
      Revenue Account that do not constitute Excess Revenue except as expressly
      provided in this Indenture without the prior written consent of the
      Trustee.

     

    (d) Excess
      Revenue shall be transferred to the Excess Revenue Account as set forth in
      Sections 5.01 and 5.02 below.

     

    (e) The
      Senior Notes are subject to mandatory redemption upon any Interest Payment
      Date,
      as a whole or in part at the principal amount thereof, plus accrued interest
      thereon to the date of redemption, but without premium, from Excess Revenues
      (the “Excess
      Revenue Offer”).

    (f) The
      Excess Revenue Offer shall remain open for a period of 20 Business Days
      following its commencement and no longer, except to the extent that a longer
      period is required by applicable law (the “Offer
      Period”).
      No
      later than five Business Days after the termination of the Offer Period (the
      “Purchase
      Date”),
      the
      Company shall purchase the maximum principal amount of Senior Notes that may
      be
      purchased with such Excess Revenue (or such pro
      rata
      portion
      based upon the principal amount of the Senior Notes tendered, if the principal
      amount of Senior Notes tendered is in excess of the Excess Revenue) (which
      maximum principal amount of Senior Notes shall be the “Offer
      Amount”)
      or, if
      less than the Offer Amount has been tendered, all Senior Notes tendered in
      response to the Excess Revenue Offer. 

     

    (g) If
      the
      Purchase Date is on or after an interest record date and on or before the
      related interest payment date, any accrued interest on the Senior Notes shall
      be
      paid to the Person in whose name a Senior Note is registered at the close of
      business on such record date, and no additional interest shall be payable to
      Holders who tender Senior Notes pursuant to the Excess Revenue Offer on the
      portion of the tendered Senior Notes purchased pursuant to the Excess Revenue
      Offer.

     

    (h) Upon
      the
      commencement of any Excess Revenue Offer, the Company shall send, by first
      class
      mail, a notice to the Trustee and each of the Holders of the Senior Notes,
      with
      a copy to the Trustee. The notice shall contain all instructions and materials
      necessary to enable such Holders to tender Senior Notes pursuant to the Excess
      Revenue Offer. The Excess Revenue Offer shall be made to all Holders. The
      notice, which shall govern the terms of the Excess Revenue Offer, shall
      state:

     

    (i) that
      the
      Excess Revenue Offer is being made pursuant to Section
      3.09
      hereof
      and the length of time the Excess Revenue Offer shall remain open;

     

    (ii) the
      Offer
      Amount, the purchase price and the Purchase Date;

     

    (iii) that
      any
      Senior Note or portion thereof not tendered or accepted for payment shall
      continue to accrue interest;

     

    (iv) that
      Holders electing to have a Senior Note or portion thereof purchased pursuant
      to
      any Excess Revenue Offer shall be required to surrender the Senior Note, with
      the form entitled “Option of Holder to Elect Purchase” on the reverse of the
      Senior Note completed, to the Company, a Depository, if appointed by the
      Company, or a Paying Agent at the address specified in the notice at least
      three
      Business Days before the Purchase Date;

     

    (v) that
      Holders shall be entitled to withdraw their election if the Company, Depository
      or Paying Agent, as the case may be, receives, not later than the expiration
      of
      the Offer Period, written communication setting forth the name of the Holder,
      the principal amount of the Senior Note or portion thereof the Holder delivered
      for purchase and a statement that such Holder is withdrawing his election to
      have the Senior Note or portion thereof purchased;

    (vi) that,
      if
      the aggregate principal amount of Senior Notes tendered by holders of such
      Senior Notes exceeds the Offer Amount, the Trustee shall select the Senior
      Notes
      to be purchased on a pro
      rata
      basis as
      described above (with such adjustments as may be deemed appropriate by the
      Trustee so that only Senior Notes in denominations of US$5,000, or integral
      multiples thereof, shall be purchased); and

     

    (vii) that
      Holders whose Senior Notes are purchased only in part shall be issued new Senior
      Notes equal in principal amount to the unpurchased portion of the Senior Notes
      surrendered (or transferred by book-entry transfer).

     

    (i) On
      the
      Purchase Date, the Company shall, to the extent lawful, accept for payment,
      on a
pro
      rata
      basis
      (as described above) to the extent necessary, the Offer Amount of Senior Notes
      or portions thereof tendered pursuant to the Excess Revenue Offer, or if less
      than the Offer Amount has been tendered, all Senior Notes or portions thereof
      tendered, and deliver to the Trustee an Officers’ Certificate stating that such
      Senior Notes or portions thereof were accepted for payment by the Company in
      accordance with the terms of this Section
      3.09.
      The
      Company or Paying Agent, as the case may be, shall promptly (but in any case
      not
      later than five days after the Purchase Date) mail or deliver to each tendering
      Holder an amount equal to the purchase price of the Senior Note or portion
      thereof tendered by such Holder and accepted by the Company for purchase, and
      the Company shall promptly issue a new Senior Note, and the Trustee shall
      authenticate and mail or deliver such new Senior Note to such Holder equal
      in
      principal amount to any unpurchased portion of the Senior Note surrendered.
      Any
      Senior Note not so accepted shall be promptly mailed or delivered by the Company
      to the Holder thereof. The Company shall publicly announce the results of the
      Excess Revenue Offer on the Purchase Date. In the event that the aggregate
      amount of Excess Revenue Proceeds exceeds the aggregate principal amount of
      Senior Notes or portion thereof surrendered by Holders of such Senior Notes
      pursuant to an Excess Revenue Offer, the Company may use the remaining Excess
      Revenue for general purposes. Upon completion of an Excess Revenue Offer, the
      amount of the Excess Revenue shall be deemed to be reset at zero.

     

    (j) Other
      than as specifically provided in this Section
      3.09,
      any
      purchase pursuant to this Section 3.09
      shall be
      made pursuant to the provisions of Sections
      3.01
      through
3.06
      hereof.

    (a) If
      a
      Change of Control occurs, the Company shall make an offer (the “Change
      of Control Offer”)
      to
      each of the Holders of Senior Notes to repurchase all or any part (equal to
      $5,000 or an integral multiple of $5,000) of that Holder’s Senior Notes pursuant
      to the Change of Control Offer at a purchase price, in cash, equal to 100%
      of
      the aggregate principal amount of Senior Notes repurchased, plus accrued and
      unpaid interest on the Senior Notes repurchased, to the Purchase Date (the
      “Change

      (subject to the right of Holders of record on the relevant Regular Record Date
      to receive interest due on the relevant Interest Payment Date).

    (b) Within

      days following any Change of Control, the Company shall mail a notice of such
      Change of Control Offer by first class mail, postage prepaid, to each Holder
      describing the transaction or transactions that constitute the Change of Control
      and stating: 

     

    (i) that
      the
      Change of Control Offer is being made pursuant to this Section
      3.10

      all Senior Notes tendered shall be accepted for payment; 

     

    (ii) the
      purchase price and the purchase date, which shall be no earlier than 30 days
      and
      no later than 60 days from the date such notice is mailed (the “Change
      of Control Payment Date”);
      

     

    (iii) that
      any
      Senior Note not tendered shall remain outstanding and continue to accrue
      interest; 

     

    (iv) that,
      unless the Company defaults in the payment of the Change of Control Payment,
      all
      Senior Notes accepted for payment pursuant to the Change of Control Offer shall
      cease to accrue interest after the Change of Control Payment Date; 

     

    (v) that
      Holders electing to have any Senior Notes purchased pursuant to a Change of
      Control Offer shall be required to surrender the Senior Notes, with the form
      entitled “Option of Holder to Elect Purchase” on the reverse of the Senior Notes
      completed, to the Paying Agent at the address specified in the notice prior
      to
      the close of business on the third Business Day preceding the Change of Control
      Payment Date; 

     

    (vi) that
      Holders shall be entitled to withdraw their election if the Paying Agent
      receives, not later than the close of business on the second Business Day
      preceding the Change of Control Payment Date, a written communication setting
      forth the name of the Holder, the principal amount of Senior Notes delivered
      for
      purchase, and a statement that such Holder is withdrawing his election to have
      such Senior Notes purchased; and 

     

    (vii) that
      Holders whose Senior Notes are being purchased only in part shall be issued
      new
      Senior Notes equal in principal amount to the unpurchased portion of the Senior
      Notes surrendered. 

     

    (c) So
      long
      as the Senior Notes are in global form, if the Company makes an offer to
      purchase all of the Senior Notes pursuant to a Change of Control Offer, a Holder
      may exercise its option to elect for the purchase of Senior Notes through the
      facilities of the Depository, subject to its rules and regulations.

      tendered the Change of Control Payment for such Senior Notes, and the Trustee

      of Control, conditional upon such Change of Control, if a definitive agreement
      is in place for the Change of Control at the time of making the Change of
      Control Offer.

      such
      indebtedness is permitted under Section

      be the unconditional obligation of the Company to make payments into the Senior
      Note Fund, unless sufficient funds exist as a result of the Revenue Fund, as
      follows:

     

    (a) For
      Payment of Interest and Trustee Fees: On
      or
      before the fifth (5th) calendar
      day of each month, there shall be paid into the Senior Note Fund, beginning
      on
      the fifth (5th) calendar day of February, 2008 (pro-rated accordingly for the
      first payment due April 15, 2008), and continuing on the fifth (5th) calendar
      day of each month thereafter, until all Outstanding Senior Notes with interest
      and premium, if any, thereon have been paid in full, or provision made for
      such
      payment, a sum (to be computed by Trustee) equal to: (i) one-third (1/3) of
      the
      installment of interest coming due on the Senior Notes on the next Interest
      Payment Date; and (ii) beginning on the fifth (5th) calendar day of February,
      2008 (pro-rated accordingly for the first payment due April 15, 2008), and
      continuing on the fifth (5th) calendar day of each month thereafter until all
      outstanding Notes with interest and premium, if any, thereon have been paid
      in
      full, or provision made for such payment, a sum (to be computed by Trustee)
      equal to one-twelfth (1/12) of Trustee’s and Paying Agent’s annual fees for the
      Senior Notes. All monies in the Senior Note Fund shall be used solely for the
      purpose of paying Annual Debt Service on the Senior Notes or for any redemption
      of the Senior Notes, plus Trustee’s and Paying Agent’s fees, except as herein
      specifically provided. Trustee shall withdraw from the Senior Note Fund, on
      the
      date of any principal or interest payment, an amount equal to the amount of
      such
      payment for the sole purpose of paying the same plus Trustee’s and Paying
      Agent’s fees, which direction Trustee hereby accepts.

    (b) For
      Payment of any Deficiency: On

      before the fifth (5th) calendar
      day of the month preceding each Interest Payment Date, there shall be paid
      by
      the Company into the Senior Note Fund until all outstanding Senior Notes with
      interest thereon have been paid in full, or provision made for such payment,
      a
      sum (to be computed by Trustee) that shall, when added to the amounts that
      have
      been transferred from the Revenue Fund as provided for in subparagraph (a)
      above, be equal to the installment of interest coming due on the Senior Notes
      (whether at maturity, upon mandatory redemption, or otherwise) on the then
      next
      Interest Payment Date, plus one-third (1/3) of Trustee’s and Paying Agent’s
      annual fees for the Notes. The obligation of the Company to pay interest and
      of
      the Trustee to transfer funds to the Subordinated Note Trustee with respect
      to
      the Subordinate Notes shall be only to the extent of available Pledged Revenues
      as set forth in subparagraph (a) above. The Subordinate Notes shall not be
      subject to this subparagraph (b). 

     

    Notwithstanding
      the above, unless the Company is notified by Trustee that insufficient funds
      exist in the Senior Note Fund to effect such coming due interest payment and
      Trustee fee payments, the Company will not make any payment to the Senior Note
      Fund.

      and
      the amounts in the Refinancing Fund representing working capital for the Company
      shall be wired into the Company’s operating accounts, as instructed by the

      Written Request from Placement Agent to Trustee on the Issue Date) to pay the
      costs of issuance of the Senior Notes issued and delivered on that date and
      such
      other amounts as shall be delivered by the Company for deposit therein shall
      be
      deposited into the Costs of Issuance Account. Monies at any time held in the
      Costs of Issuance Account shall be used for and applied solely to pay costs
      of
      issuance of the Notes, including underwriting, consultants, legal, printing,
      publication, trustee, paying agent and financial advisory fees and expenses.
      Payments from the Costs of Issuance Account shall be made by Trustee, upon
      receipt of a Written Request, signed by an appropriate Officer of the Company.
      Upon receipt of each such Written Request, Trustee shall pay each such item
      directly to the person or party entitled thereto as named in such authorization.
      Nothing in Section 5.03, above, or elsewhere in this Indenture shall be
      construed to prohibit the Company from directly paying some or all of the Costs
      of Issuance without utilizing the Costs of Issuance Account. 

     

    After
      payment of the funds directed by the Written Request, Trustee shall wire the
      balance of monies in the Costs of Issuance Account to the Company’s operating
      account, as instructed by the Company, for use by the Company, without further
      restriction.

    If
      any
      Event of Default occurs and is continuing with respect to this Indenture and
      the
      Senior Notes, the Trustee or the Holders of at least 25% of the aggregate
      principal amount of the then outstanding Senior Notes may declare all the Senior
      Notes to be due and payable immediately. Upon such declaration, the principal
      of, premium, if any, and accrued and unpaid interest on the Senior Notes shall
      be due and payable immediately. Notwithstanding the foregoing, in the case
      of an
      Event of Default arising from any of the events described in Section
      7.01(h),
      or in
      the event the Company fails to make any payment when due under clauses (a)
      and
      (b) of Section
      7.01,
      all
      outstanding Senior Notes will become due and payable without further action
      or
      notice. Holders of the Senior Notes may not enforce the Indenture or the Senior
      Notes except as provided in this Indenture. Subject to certain limitations,
      Holders of a majority in principal amount of the then outstanding Senior Notes
      may direct the Trustee in its exercise of any trust or power. The Trustee may
      withhold from Holders of the Senior 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 the
      best interest of the Holders.

     

    In
      the
      case of any Event of Default occurring by reason of any willful action (or
      inaction) taken (or not taken) by or on behalf of the Company with the intention
      of avoiding payment of the premium that the Company would have had to pay if
      the
      Company then had elected to redeem the Senior Notes pursuant to Section
      3.07
      hereof,
      an equivalent premium shall also become and be immediately due and payable
      upon
      the acceleration of the Senior Notes.

    If
      an
      Event of Default occurs and is continuing, the Trustee may pursue any available
      remedy, to collect the payment of principal, premium, if any, and interest
      on
      the Senior Notes or to enforce the performance of any provision of the Senior
      Notes or this Indenture.

     

    The
      Trustee may maintain a proceeding even if it does not possess any of the Senior
      Notes or does not produce any of them in the proceeding. A delay or omission
      by
      the Trustee or any Holder of a Senior Note in exercising any right or remedy
      accruing upon an Event of Default shall not impair the right or remedy or
      constitute a waiver of or acquiescence in the Event of Default. All remedies
      are
      cumulative to the extent permitted by law.

      and
      its consequences, except a continuing Default or Event of Default in the payment
      of the principal of, premium, if any, or interest on, the Senior Notes. Upon
      any
      such waiver, such Default shall cease to exist, and any Event of Default arising
      therefrom shall be deemed to have been cured for every purpose of this
      Indenture; but no such waiver shall extend to any subsequent or other Default
      or
      Event of Default or impair any right consequent thereon.

      determines may be unduly prejudicial to the rights of other Holders of Senior

    (a) If
      an
      Event of Default has occurred and is continuing, the Trustee shall exercise
      such
      of the rights and powers vested in it by this Indenture and use the same degree
      of care and skill in their exercise as a prudent man would exercise or use
      under
      the circumstances in the conduct of his own affairs.

     

    (b) Except
      during the continuance of an Event of Default:

     

    (i) the
      duties of the Trustee shall be determined solely by the express provisions
      of
      this Indenture and the Trustee need perform only those duties that are
      specifically set forth in this Indenture and no others, and no implied covenants
      or obligations shall be read into this Indenture against the Trustee;
      and

     

    (ii) in
      the
      absence of bad faith on its part, the Trustee may conclusively rely, as to
      the
      truth of the statements and the correctness of the opinions expressed therein,
      upon certificates or opinions furnished to the Trustee and conforming to the
      requirements of this Indenture. However, the Trustee shall examine the
      certificates and opinions to determine whether or not they conform to the
      requirements of this Indenture.

     

    (c) The
      Trustee may not be relieved from liabilities for its own negligent action,
      its
      own negligent failure to act, or its own willful misconduct, except
      that:

     

    (i) this
      paragraph does not limit the effect of paragraph (b) of this Section 8.01;

     

    (ii) the
      Trustee shall not be liable for any error of judgment made in good faith by
      a
      Responsible Officer, unless it is proved that the Trustee was negligent in
      ascertaining the pertinent facts; and

     

    (iii) the
      Trustee shall not be liable with respect to any action it takes or omits to
      take
      in good faith in accordance with a direction received by it pursuant to
Section
      7.05
      hereof.

     

    (d) Whether
      or not therein expressly so provided, every provision of this Indenture that
      in
      any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of
      this Section 8.01.

      own
      funds or incur any liability. The Trustee shall be under no obligation to
      exercise any of its rights and powers under this Indenture at the request of
      any
      Holders of Senior Notes, unless such Holder shall have provided to the Trustee
      security and indemnity satisfactory to the Trustee against any loss, liability
      or expense.

     

    (f) The
      Trustee shall not be liable for interest on any money received by it except
      as
      the Trustee may agree in writing with the Company. Money held in trust by the
      Trustee need not be segregated from other funds except to the extent required

    (a) The
      Trustee may conclusively rely upon any document believed by it to be genuine
      and
      to have been signed or presented by the proper Person. The Trustee need not
      investigate any fact or matter stated in the document.

     

    (b) Before
      the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel or both. The Trustee shall not be liable
      for any action it takes or omits to take in good faith in reliance on such
      Officers’ Certificate or Opinion of Counsel. The Trustee may consult with
      counsel and the advice of such counsel or any Opinion of Counsel shall be full
      and complete authorization and protection from liability in respect of any
      action taken, suffered or omitted by it hereunder in good faith and in reliance
      thereon.

     

    (c) The
      Trustee may act through its attorneys and agents and shall not be responsible
      for the misconduct or negligence of any agent appointed with due

    The
      Company shall compensate the Trustee for its acceptance of this Indenture and
      services hereunder as follows: $3,500.00. The Trustee’s compensation shall not
      be limited by any law on compensation of a trustee of an express trust. The
      Company shall reimburse the Trustee promptly upon written request for all
      reasonable disbursements, advances and expenses incurred or made by it in
      addition to the compensation for its services. Such expenses shall include
      the
      reasonable compensation, disbursements and expenses of the Trustee’s agents and
      counsel.

     

    The
      Company shall indemnify the Trustee against any and all losses, liabilities
      or
      expenses incurred by it arising out of or in connection with the acceptance
      or
      administration of its duties under this Indenture, except any such loss,
      liability or expense as may be attributable to the negligence or bad faith
      of
      the Trustee. The Trustee shall notify the Company promptly of any claim for
      which it may seek indemnity. Failure by the Trustee to so notify the Company
      shall not relieve the Company of its obligations hereunder. The Company shall
      defend the claim and the Trustee shall cooperate in the defense. The Trustee,
      in
      its sole discretion, may elect to have separate counsel selected by it and
      the
      Company shall pay the reasonable fees and expenses of such counsel. The Company
      need not pay for any settlement made without its written consent, which consent
      shall not be unreasonably withheld.

     

    The
      obligations of the Company under this Section
      8.07
      shall
      survive the satisfaction and discharge of this Indenture.

     

    To
      secure
      the Company payment obligations in this Section 8.07,
      the
      Trustee shall have a Lien prior to the Senior Notes on all money or property
      held or collected by the Trustee, except that held in trust to pay principal,
      premium, if any, and interest on particular Senior Notes. Such Lien shall
      survive the satisfaction and discharge of this Indenture.

     

    When
      the
      Trustee incurs expenses or renders services after an Event of Default specified
      in Section 7.01(g)
      or
(h)
      hereof
      occurs, the expenses and the compensation for the services (including the fees
      and expenses of its agents and counsel) are intended to constitute expenses
      of
      administration under any Bankruptcy Law.

      a
      majority in principal amount of the then outstanding Senior Notes may remove
      the
      Trustee by so notifying the Trustee and the Company in writing. The Company
      may

    (b) the
      Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered
      with respect to the Trustee under any Bankruptcy Law;

     

    (c) a
      Custodian or public officer takes charge of the Trustee or its property;
      or

     

    (d) the

    If
      the
      Trustee resigns or is removed or if a vacancy exists in the office of Trustee
      for any reason, the Company shall promptly appoint a successor Trustee. Within
      one year after the successor Trustee takes office, the Holders of a majority
      in
      principal amount of the then outstanding Senior Notes may appoint a successor
      Trustee to replace the successor Trustee appointed by the Company.

     

    If
      a
      successor Trustee does not take office within 60 days after the retiring Trustee
      resigns or is removed, the retiring Trustee, the Company, or the Holders of
      Senior Notes of at least 10% in principal amount of the then outstanding Senior
      Notes may petition any court of competent jurisdiction for the appointment
      of a
      successor Trustee.

     

    If
      the
      Trustee after written request by any Holder of a Senior Note who has been a
      Holder of a Senior Note for at least six months fails to comply with Section
      8.10
      hereof,
      such Holder of a Senior Note may petition any court of competent jurisdiction
      for the removal of the Trustee and the appointment of a successor
      Trustee.

     

    A
      successor Trustee shall deliver a written acceptance of its appointment to
      the
      retiring Trustee and to the Company. Thereupon the resignation or removal of
      the
      retiring Trustee shall become effective, and the successor Trustee shall have
      all the rights, powers and duties of the Trustee under this Indenture. The
      successor Trustee shall mail a notice of its succession to Holders of the Senior
      Notes. The retiring Trustee shall promptly transfer all property held by it
      as
      Trustee to the successor Trustee, provided all sums owing to the Trustee
      hereunder have been paid and subject to the Lien provided for in Section
8.07
      hereof.
      Notwithstanding replacement of the Trustee pursuant to this Section 8.08,
      the
      Company’s obligations under Section 8.07

      shall continue for the benefit of the retiring Trustee.

      that (A) the Company has received from, or there has been published by, the
      United States Internal Revenue Service a ruling or (B) since the Issue Date,
      there has been a change in the applicable United States federal income tax
      law,
      in either case to the effect that, and based thereon such opinion of counsel
      shall confirm that, the Holders of the outstanding Senior Notes will not
      recognize income, gain or loss for federal income tax purposes as a result
      of
      such legal defeasance and will be subject to federal income tax on the same
      amounts, in the same manner and at the same times as would have been the case
      if
      such legal defeasance had not occurred;

     

    (c) in
      the
      case of covenant defeasance, the Company must deliver to the Trustee an opinion
      of counsel in the United States reasonably acceptable to the Trustee confirming
      that the Holders of the outstanding Senior Notes will not recognize income,
      gain
      or loss for United States federal income tax purposes as a result of such
      covenant defeasance and will be subject to United States federal income tax
      on
      the same amounts, in the same manner and at the same times as would have been
      the case if such covenant defeasance had not occurred;

     

    (d) no
      Default or Event of Default shall have occurred and be continuing on the date
      of
      such deposit (other than a Default or Event of Default resulting from the

      Default from bankruptcy or insolvency events are concerned, at any time in
      the
      period ending on the 91st day after the date of deposit;

     

    (e) such
      legal defeasance or covenant defeasance will not result in a breach or violation
      of, or constitute a default under, any material agreement or instrument (other
      than the Indenture) to which the Company or any of its Restricted Subsidiaries
      is a party or by which the Company or any of its Restricted Subsidiaries is
      bound;

     

    (f) the
      Company must have delivered to the Trustee an opinion of counsel to the effect
      that after the 91st day (or such other applicable date) following the deposit,
      the trust funds will not be subject to the effect of any applicable bankruptcy,
      insolvency, reorganization or similar laws affecting creditors’ rights
      generally;

     

    (g) the
      Company must deliver to the Trustee an Officers’ Certificate stating that the
      deposit was not made by the Company with the intent of preferring the Holders
      of
      Senior Notes over the other creditors of the Company with the intent of
      defeating, hindering, delaying or defrauding creditors of the Company or others;
      and

     

    (h) the
      Company must deliver to the Trustee an Officers’ Certificate and an opinion of
      counsel, each stating that all conditions precedent provided for relating to
      the
      legal defeasance or the covenant defeasance have been complied
      with.

      imposed on or assessed against the cash or Government Securities deposited
      pursuant to Section 8.04 hereof or the principal and interest received in
      respect thereof other than any such tax, fee or other charge which by law is

    Notwithstanding
      Section 10.02
      hereof,
      the Company and the Trustee may amend or supplement this Indenture or the Senior
      Notes without the consent of any Holder of a Senior Note:

     

    (a) to
      cure
      any ambiguity, defect or inconsistency;

      of the Senior Notes or that does not adversely affect the legal rights under
      this Indenture of any such Holder;

    Upon

      execution of any such amended or supplemental Indenture, and upon receipt by
      the
      Trustee of the documents described in Section 10.06

    (a) The
      Company and the Trustee may amend or supplement this Indenture or the Senior
      Notes or any amended or supplemental Indenture with the written consent of
      the
      Holders of Senior Notes of at least a majority in aggregate principal amount
      of
      the Senior Notes then outstanding (including consents obtained in connection
      with a tender offer or exchange offer for the Senior Notes), and any existing
      Default and its consequences or compliance with any provision of this Indenture,
      the Senior Notes or any document related thereto may be waived with the consent
      of the Holders of a majority in principal amount of the then outstanding Senior
      Notes (including consents obtained in connection with a tender offer or exchange
      offer for the Senior Notes).

     

    (b) Upon
      the
      request of the Company accompanied by a Board Resolution authorizing the
      execution of any such amended or supplemental Indenture, and upon the filing
      with the Trustee of evidence satisfactory to the Trustee of the consent of
      the
      Holders of Senior Notes as aforesaid, and upon receipt by the Trustee of the
      documents described in Section 10.06
      hereof,
      the Trustee shall join with the Company in the execution of such amended or
      supplemental Indenture unless such amended or supplemental Indenture affects
      the
      Trustee’s own rights, duties or immunities under this Indenture or otherwise, in
      which case the Trustee may in its discretion, but shall not be obligated to,
      enter into such amended or supplemental Indenture.

     

    (c) It
      shall
      not be necessary for the consent of the Holders of Senior Notes under this
      Section 10.02
      to
      approve the particular form of any proposed amendment or waiver, but it shall
      be
      sufficient if such consent approves the substance thereof.

     

    (d) After
      an
      amendment, supplement or waiver under this Section 10.02
      becomes
      effective, the Company shall mail to the Holders of Senior Notes affected
      thereby a notice briefly describing the amendment, supplement or waiver. Any
      failure of the Company to mail such notice, or any defect therein, shall not,
      however, in any way impair or affect the validity of any such amended or
      supplemental Indenture or waiver. Subject to Sections 7.04
      and
7.07
      hereof,
      the Holders of a majority in aggregate principal amount of the Senior Notes
      then
      outstanding may waive compliance in a particular instance by the Company with
      any provision of this Indenture or the Senior Notes. However, without the
      consent of each Holder affected, an amendment or waiver may not (with respect
      to
      any Senior Notes held by a non-consenting Holder):

     

    (i) reduce
      the principal amount of Senior Notes whose Holders must consent to an amendment,
      supplement or waiver;

     

    (ii) reduce
      the principal of or change the fixed maturity of any Senior Note or alter the
      provisions with respect to the redemption of the Senior Notes;

    (iv) waive
      a
      Default or Event of Default in the payment of principal of or premium, if any,
      or interest on, the Senior Notes (except a rescission of acceleration of the
      Senior Notes by the Holders of at least a majority in aggregate principal amount
      of the Senior Notes and a waiver of the payment default that resulted from
      such
      acceleration);

      Notes;

      change in the provisions of this Indenture relating to waivers of past Defaults
      or the rights of Holders of Senior Notes to receive payments of principal of,

    (vii) waive
      a
      redemption payment with respect to any Senior Note; or

     

    (viii) make
      any
      change in the foregoing amendment and waiver provisions.

    Until
      an
      amendment, supplement or waiver becomes effective, a consent to it by a Holder
      of a Senior Note is a continuing consent by the Holder of a Senior Note and
      every subsequent Holder of a Senior Note or portion of a Senior Note that
      evidences the same debt as the consenting Holder’s Senior Note, even if notation
      of the consent is not made on any Senior Note. However, any such Holder of
      a
      Senior Note or subsequent Holder of a Senior Note may revoke the consent as
      to
      its Senior Note if the Trustee receives written notice of revocation before
      the
      date the waiver, supplement or amendment becomes effective. An amendment,
      supplement or waiver becomes effective in accordance with its terms and
      thereafter binds every Holder of a Senior Note.

     

    The
      Company may fix a record date for determining which Holders of the Senior Notes
      must consent to such amendment, supplement or waiver. If the Company fixes
      a
      record date, the record date shall be fixed at (i) the later of 30 days prior
      to
      the first solicitation of such consent or the date of the most recent list
      of
      Holders of Senior Notes furnished to the Trustee prior to such solicitation
      pursuant to Section 2.05
      hereof
      or (ii) such other date as the Company shall designate.

      that reflect the amendment, supplement or waiver.

     

    Failure
      to make the appropriate notation or issue a new Senior Note shall not affect

      validity and effect of such amendment, supplement or waiver.

      under this Article

      notwithstanding any extension or renewal of any such obligation.

    Each
      Guarantor hereby agrees that its obligations with regard to its Guarantee shall
      be joint and several, unconditional, irrespective of the validity or
      enforceability of the Senior Notes or the Senior Note Obligations, the absence
      of any action to enforce the same or any other circumstances (other than
      complete performance) which might otherwise constitute a legal or equitable
      discharge or defense of a Guarantor. Each Guarantor further, to the fullest
      extent permitted by applicable law, waives presentation to, demand of, payment
      from and protest to the Company of any of the obligations and also waives notice
      of protest for nonpayment. Each Guarantor waives notice of any default under
      the
      Senior Notes or any Senior Note Obligation. The obligations of each Guarantor
      hereunder shall not be affected by (1) the failure of any Holder or the Trustee
      to assert any claim or demand or to enforce any right or remedy against the
      Company or any other Person (including any Guarantor) under this Indenture,
      the
      Senior Notes or any other Senior Note Documents or otherwise; (2) any extension
      or renewal of any thereof; (3) any rescission, waiver, amendment or modification
      of any of the terms or provisions of this Indenture, the Senior Note Documents
      or any other agreement; (4) the release of any security held by any Holder
      or
      the Collateral Agent for the Senior Note Obligations or any of them; (5) the
      failure of any Holder or the Collateral Agent to exercise any right or remedy
      against any other guarantor of the obligations; or (6) except as set forth
      in
      Section 11.06,
      any
      change in the ownership of such Subsidiary Guarantor.

     

    Each
      Guarantor further agrees that its Guarantee herein constitutes a guarantee
      of
      payment, performance and compliance when due (and not a guarantee of collection)
      and waives any right to require that any resort be had by any Holder or the
      Trustee to any security held for payment of the obligations.

     

    Except
      as
      expressly set forth in Sections 9.02
      and
11.06,
      the
      Obligations of each Guarantor hereunder shall not be subject to any reduction,
      limitation, impairment or termination for any reason, including any claim of
      waiver, release, surrender, alteration or compromise, and shall not be subject
      to any defense of setoff, counterclaim, recoupment or termination whatsoever
      or
      by reason of the invalidity, illegality or unenforceability of the Senior Note
      Obligations or otherwise. Without limiting the generality of the foregoing,
      the
      obligations of each Guarantor herein shall not be discharged or impaired or
      otherwise affected by the failure of any Holder, the Trustee or the Collateral
      Agent to assert any claim or demand or to enforce any remedy under this
      Indenture, the Senior Notes, any Senior Note Documents or any other agreement,
      by any waiver or modification of any thereof, by any default, failure or delay,
      willful or otherwise, in the performance of the Senior Note Obligations, or
      by
      any other act or thing or omission or delay to do any other act or thing which
      may or might in any manner or to any extent vary the risk of such Guarantor
      or
      would otherwise operate as a discharge of such Guarantor as a matter of law
      or
      equity.

     

    Each
      Guarantor further agrees that its Guarantee herein shall continue to be
      effective or be reinstated, as the case may be, if at any time payment, or
      any
      part thereof, of principal of or interest on any Senior Note Obligation or
      Guarantee’s obligations is rescinded or must otherwise be restored by any Holder
      or the Trustee upon the bankruptcy or reorganization of the Company, any
      Guarantor or otherwise.

     

    In
      furtherance of the foregoing and not in limitation of any other right which
      any
      Holder or the Trustee has at law or in equity against any Guarantor by virtue
      hereof, upon the failure of the Company to pay the principal of or interest
      on
      any Senior Note Obligation when and as the same shall become due, whether at
      maturity, by acceleration, by redemption or otherwise, or to perform or comply
      with any other obligation, each Guarantor hereby promises to and shall, upon
      receipt of written demand by the Trustee, forthwith pay, or cause to be paid,
      in
      cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid
      amount of such obligations, (B) accrued and unpaid interest on such obligations
      (but only to the extent not prohibited by law) and (C) all other monetary
      obligations of the Company to the Holders and/or the Trustee.

      the
      Trustee, on the other hand, (i) the maturity of the Senior Note Obligations
      Guaranteed hereby may be accelerated as provided in Section 702
      for the
      purposes of such Guarantor’s Guarantee herein, notwithstanding any stay,
      injunction or other prohibition preventing such acceleration in respect of
      the
      obligations guaranteed hereby, and (ii) in the event of any declaration of
      acceleration of such obligations as provided in Section 702,
      such
      obligations (whether or not due and payable) shall forthwith become due and
      payable by such Guarantor for the purposes of this Section 11.1.

     

    Each
      Guarantor also agrees to pay any and all costs and expenses (including
      reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing
      any rights under this Section.

      11
      (other
      than any obligation that shall have arisen under Section 11.07):

     

    (a) upon

      consolidation, sale or other disposition of all of the assets of such Guarantor,
      sale or other disposition of all of the Equity Interests of such Guarantor
      or
      otherwise) other than a transaction that constitutes a sale of all or
      substantially all of the assts of the Company so as to trigger a Change of

    provided,
      however,
      that in

      other than the Company or an Affiliate. At the request of the Company, the

    (a) Subject
      to subsections (b), (c), (d) and (e) of this Section 12.03
      and the
      Intercreditor Agreement, Collateral may be released from the Lien and security
      interest created by the Senior Note Collateral Documents at any time or from
      time to time in accordance with the provisions of the Senior Note Collateral
      Documents, the Intercreditor Agreement or as provided hereby. In addition,
      subject to the terms of the Intercreditor Agreement, upon the request of the
      Company pursuant to an Officers’ Certificate certifying that all conditions
      precedent under the Indenture have been met, then (at the sole cost and expense
      of the Company) the Collateral Agent shall release (or cause to be released)
      Senior Note Collateral that is sold, conveyed or disposed of in compliance
      with
      the provisions of this Indenture; provided,
      the
      Company will apply any Net Proceeds in compliance with Section
      4.11.
      Upon
      receipt of such Officers’ Certificate the Collateral Agent shall promptly
      execute, deliver or acknowledge any necessary or proper instruments of
      termination, satisfaction or release to evidence the release of any Collateral
      permitted to be released pursuant to this Indenture, the Senior Note Collateral
      Documents or the Intercreditor Agreement. 

     

    (b) No
      Collateral may be released from the Lien and security interest created by the
      Senior Note Collateral Documents pursuant to the provisions of the Senior Note
      Collateral Documents and the Intercreditor Agreement unless the certificate
      required by this Section 12.03
      has been
      delivered to the Collateral Agent. 

     

    (c) At
      any
      time when a Default or Event of Default has occurred and is continuing and
      the
      maturity of the Senior Notes has been accelerated (whether by declaration or
      otherwise) and the Trustee shall have delivered a notice of acceleration to
      the
      Collateral Agent, no release of Collateral pursuant to the provisions of the
      Senior Note Collateral Documents and the Intercreditor Agreement will be
      effective as against the Holders. 

     

    (d) The
      release of any Senior Note Collateral from the terms of this Indenture, the
      Senior Note Collateral Documents and the Intercreditor Agreement shall not
      be
      deemed to impair the security under this Indenture in contravention of the
      provisions hereof if and to the extent the Senior Note Collateral is released
      pursuant to the terms of the Senior Note Collateral Documents, this Indenture
      and the Intercreditor Agreement. To the extent applicable, the Company shall
      cause TIA § 313(b), relating to reports, and TIA § 314(d), relating to the
      release of property or securities from the Lien and security interest of the
      Senior Note Collateral Documents and relating to the substitution therefor
      of
      any property or securities to be subjected to the Lien and security interest
      of
      the Senior Note Collateral Documents, to be complied with. Any certificate
      or
      opinion required by TIA § 314(d) may be made by an Officer of the Company except
      in cases where TIA § 314(d) requires that such certificate or opinion be made by
      an independent Person, which Person shall be an independent engineer, appraiser
      or other expert selected or approved by the Trustee and the Collateral Agent
      in
      the exercise of reasonable care.

     

    (e) Notwithstanding

              Rules

    The
      Trustee may make reasonable rules for action by or at a meeting of Holders
      of
      Senior Notes. The Registrar or Paying Agent may make reasonable rules and set
      reasonable requirements for its functions.

    No
      director, officer, employee, incorporator or stockholder of the Company or
      any
      Guarantor, as such, shall have any liability for any obligations of the Company
      or any Restricted Subsidiary under the Senior Notes or this Indenture or for
      any
      claim based on, in respect of, or by reason of, such obligations or their
      creation. Each Holder of the Senior Notes by accepting a Senior Note waives
      and
      releases all such liability. The waiver and release are part of the
      consideration for issuance of the Senior Notes. Such waiver may not be effective
      to waive liabilities under United States federal securities laws and it is
      the
      view of the Commission that such a waiver is against public policy.

      of
      law that would cause application of the laws of any jurisdiction other than
      the
