    Representations
      And
      Warranties

     

    Section
      3.01.  Representations
      and Warranties of the Credit Parties.  Each Credit Party, with
      respect to itself and its Subsidiaries, represents and warrants to the
      Collateral Agent, for the benefit of the Secured Parties, that:

     

    (a)  With
      respect to any
      Credit Party that is a Grantor:  (i) such Credit Party’s exact legal
      name is correctly set forth in Schedule III, (ii) such Credit Party is located
      (within the meaning of Section 9-307 of the UCC) and has its chief executive
      office, in the state or jurisdiction set forth in Schedule III, (iii) the
      information set forth in Schedule III with respect to such Credit Party is
      true
      and accurate in all respects and (iv) such Credit Party has not, within the
      last
      five years, changed its legal name, location, chief executive office, type
      of
      organization, jurisdiction of organization or organizational identification
      number from those set forth in Schedule III, except as disclosed in Schedule
      IV.

     

    (b)  Such
      Credit Party
      is duly organized or formed, validly existing and, if applicable, in good
      standing in its jurisdiction of organization or formation.  Such
      Credit Party possesses all applicable Business Entity powers and all other
      authorizations and licenses necessary to engage in its business and operations
      as now conducted, the failure to obtain or maintain which would have a Material
      Adverse Effect.

     

    (c)  The
      execution,
      delivery and performance by such Credit Party of the Security Documents to
      which
      it is a party are within such Credit Party’s applicable Business Entity powers,
      have been duly authorized by all necessary applicable Business Entity action,
      and do not contravene (i) such Credit Party’s organizational documents or (ii)
      any material contractual restriction binding on or affecting such Credit
      Party.

     

    (d)  No
      authorization or
      approval or other action by, and no notice to or filing with, any Governmental
      Authority is required for the due execution, delivery and performance by such
      Credit Party of any Security Document to which it is a party, except those
      necessary to comply (i) with Applicable Laws in the ordinary course of such
      Credit Party’s business or (ii) with ongoing obligations of such Credit Party
      under the Security Documents to which it is a party and Sections 5.01, 5.02
      and
      5.07 of the Credit Agreement.

     

    (e)  This
      Agreement
      constitutes, and the other Security Documents when delivered shall constitute,
      the legal, valid and binding obligations of each Credit Party that is a party
      thereto, enforceable against such Credit Party in accordance with their
      respective terms, except as may be limited by any applicable bankruptcy,
      insolvency, reorganization, moratorium or similar laws affecting creditors’
rights generally or by general principles of equity.

     

    (f)  With
      respect to any
      Credit Party that is a Grantor, all Collateral pledged by such Credit Party
      hereunder consisting of certificated securities has been delivered to the
      Collateral Agent.

     

    (g)  With
      respect to any
      Credit Party that is a Grantor, this Agreement is effective to create in favor
      of the Collateral Agent, for the ratable benefit of the Secured Parties, a
      Lien
      on, and security interest in, all right, title and interest of such Grantor
      in
      the Collateral pledged by such Credit Party hereunder as security for the
      Secured Obligations, prior and superior in right to any other Lien (except
      for
      Collateral Permitted Liens), except in each case above as may be limited by
      any
      applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
      affecting creditors’ rights generally.  All financing statements have
      been filed that are necessary to perfect any Transaction Lien that can be
      perfected by the filing of such financing statements.  All actions
      required by Section 5.03 to provide control to the
      Collateral Agent with respect to Collateral pledged by such Credit Party
      hereunder for which control can be established have been taken, including
      delivery of such Collateral consisting of certificated securities to the
      Collateral Agent, duly endorsed for transfer or accompanied by duly executed
      instruments of transfer.

     

    (h)  With
      respect to any
      Credit Party that is a Grantor, the Pledged Equity pledged as Collateral by
      such
      Credit Party to the Collateral Agent hereunder has (to the extent applicable)
      been duly authorized and validly issued and is (to the extent applicable) fully
      paid and non-assessable.  With respect to any Equity Interests pledged
      by such Credit Party to the Collateral Agent hereunder that are uncertificated
      securities, such Credit Party has caused the issuer thereof to agree in an
      authenticated record with such Credit Party and the Collateral Agent that such
      issuer will comply with instructions with respect to such uncertificated
      securities originated by the Collateral Agent without further consent of such
      Credit Party and has delivered a copy of such authenticated record to the
      Collateral Agent.  If such Credit Party is a Pledged Company, such
      Credit Party confirms that it has received notice of such security
      interest.

     

    (i)  With
      respect to any
      Credit Party that is a Grantor, the Initial Pledged Equity as set forth on
      Schedule II (as such schedule may be amended or supplemented from time to time)
      pledged as Collateral by such Credit Party to the Collateral Agent hereunder
      constitutes 100% of the issued and outstanding Equity Interests of each issuer
      thereof.

     

    All
      representations
      and warranties made by the Credit Parties herein, and in any other Security
      Document delivered pursuant hereto, shall survive the execution and delivery
      by
      the Credit Parties of the Security Documents.  The Credit Parties
      shall deliver to the Collateral Agent amended and restated schedules (the
“Amended Schedules”) to this Agreement in the event that any
      information contained on the schedules attached hereto becomes
      inaccurate.  Such Amended Schedules shall replace the schedules
      provided by the Credit Parties on the Effective Date, and shall be deemed the
      schedules to this Agreement. Each Credit Party will not change its name,
      identity, corporate structure (including, without limitation, its jurisdiction
      of formation) or the location of its registered office without (i) giving the
      Collateral Agent at least 10 Business Days’ prior written notice clearly
      describing such new name, identity, corporate structure or new location and
      providing such other information in connection therewith as the Collateral
      Agent
      may reasonably request, and (ii) taking all action satisfactory to the
      Collateral Agent at the expense of such Credit Party as the Collateral Agent
      may
      request to maintain the security interest of the Collateral Agent in the
      Collateral intended to be granted hereby at all times fully perfected with
      the
      same priority and in full force and effect.

      Accounts

     

    Section
      4.01.  Creation
      of Pledged Accounts.  (a) The Collateral Agent is hereby directed
      by the Company and each Grantor to cause to be established on or before the
      date
      hereof with, and maintained thereafter by, the Depository Bank at its offices
      in
      New York City, New York (ABA No. 021000021), in the name of the Collateral
      Agent
      as entitlement holder and under the sole control and dominion of the Collateral
      Agent and subject to the terms of this Agreement, the following segregated
      securities accounts (collectively, the “Pledged
      Accounts”):

     

    (i)  a
      master collateral
      account, Account No. 10205184 (the “Collateral Account”), into
      which Mandatory Asset Reduction Amounts will be deposited and to which Unused
      Cash Collateral and certain amounts described in Section
      4.03(f) will be transferred;

     

    (ii)  a
      cash collateral
      account, Account No. 10205185 (the “Cash Collateral Account”),
      into which certain amounts will be deposited in respect of Letters of Credit;
      and

     

    (iii)  an
      account, Account
      No. 10205186 (the “Qualified Investments Account”), from which
      the Company, on behalf of the Restricted Subsidiaries, may direct the Collateral
      Agent to direct the Depository Bank to pay funds to the Company to make
      Qualified Investments as permitted under the Loan Documents.

     

    (b)  Commencing
      with the
      date hereof and continuing until the termination of the Transaction Liens in
      accordance with Section 5.07(b), each Pledged
      Account shall be established and maintained by the Depository Bank as a
      securities account or as a deposit account at its offices in New York City,
      New
      York, in the name of and under the sole dominion and control of the Collateral
      Agent; provided that the Cash Collateral Account may be terminated at
      such time as:  (i) all Letters of Credit shall have expired or been
      paid, settled, satisfied, released, or otherwise terminated, (ii) all LC
      Disbursements shall have been reimbursed, (iii) all LC Commitments and all
      commitments of the Lenders to participate in Letters of Credit shall have been
      terminated and (iv) all amounts on deposit in the Cash Collateral Account shall
      have been transferred to the Collateral Account as Unused Cash Collateral,
      to be
      applied in accordance with Section 2.09 of the Credit Agreement and Section 6.02.  The Collateral Agent shall
      cause each of the Pledged Accounts to be, and each Pledged Account shall be,
      separate from all other accounts held by or under the control or dominion of
      the
      Collateral Agent.  The Company irrevocably confirms the authority of
      (and directs and authorizes) the Collateral Agent to, or to direct the
      Depository Bank to, and the Collateral Agent agrees to, or to direct the
      Depository Bank to, deposit into, or credit to, and transfer funds from the
      Pledged Accounts to the Collateral Agent, the Administrative Agent, the other
      Secured Parties and the Company (or its designee), in each case in accordance
      with this Agreement and the other Loan Documents.

     

    (c)  The
      Credit Parties
      acknowledge that the Collateral Agent may cause the Depository Bank to establish
      subaccounts of the Qualified Investments Account, and that such subaccounts
      may,
      at the Collateral Agent’s election, be either (i) actual, separate accounts or
      (ii) notional accounts reflected in the Collateral Agent’s records as accounting
      entries with respect to the actual Qualified Investments Account maintained
      by
      the Depository Bank.  Each such subaccount shall constitute a Pledged
      Account hereunder, and each actual subaccount shall be established and
      maintained by the Depository Bank as a securities account at its offices in
      New
      York City, New York, in the name of the Collateral Agent.

     

    (d)  Unless
      otherwise
      specified in this Agreement, all references to the Qualified Investments Account
      shall include references to all subaccounts thereof, and such subaccounts shall
      be subject to the same restrictions and limitations as the Qualified Investments
      Account.

     

    (e)  The
      Company shall
      not have any rights against or to moneys or funds on deposit in, or credited
      to,
      the Pledged Accounts, as third-party beneficiary or otherwise, except the right
      of the Company (a) to receive moneys or funds on deposit in, or credited to,
      the
      Pledged Accounts, as required or permitted by this Agreement or by the
      provisions of any other Loan Document (to the extent such provisions are not
      inconsistent with this Agreement), and (b) to direct the Collateral Agent as
      to
      the investment of moneys held in the Pledged Accounts as permitted by Section 4.05.  In no event shall any amounts
      or Cash Equivalents deposited into, or credited to, any Pledged Account, be
      registered in the name of the Company, payable to the order of the Company,
      or
      specially endorsed to the Company, except to the extent that the foregoing
      have
      been specially endorsed to the Depository Bank or endorsed in
      blank.

     

    Section
      4.02.  Cash
      Collateral Account.  (a) [Reserved]

     

    (b)  Amounts
      deposited
      in the Cash Collateral Account shall be held therein, subject to the following
      provisions:

     

    (i)  If
      any Letter of
      Credit is drawn, in whole or in part, and not reimbursed by the applicable
      Borrower within the period specified in Section 2.04(e) of the Credit Agreement,
      the Issuing Bank with respect to such Letter of Credit may request, whereupon
      the Collateral Agent shall within three Business Days after receipt of such
      request, direct the Depository Bank to promptly distribute to such Issuing
      Bank
      an amount equal to the lesser of (x) the amount of the LC Disbursement in
      respect of such Letter of Credit that has not been reimbursed by or on behalf
      of
      such Borrower and (y) the total amount available in the Cash Collateral Account
      at such time.

     

    (ii)  Upon
      the request of
      the Company at a time when no Event of Default is continuing, the Collateral
      Agent shall direct the Depository Bank to distribute any funds in the Cash
      Collateral Account (other than, prior to the Final Payment Date, funds deposited
      in the Cash Collateral Account pursuant to Section 2.09(c) of the Credit
      Agreement) to the Company (or to the Company’s designee) to be used by the
      Company for general corporate purposes, or to be used by such designee for
      any
      lawful purpose.

     

    (iii)  If
      an Event of
      Default shall have occurred and be continuing, the Collateral Agent may, at
      the
      direction of the Majority Lenders, apply funds in the Cash Collateral Account
      in
      accordance with Section 6.02.

     

    (c)  If
      any Letter of
      Credit, or any portion thereof, has terminated, expired or otherwise been
      released or satisfied undrawn and, as a result, the total amount of funds in
      the
      Cash Collateral Account, as of such date, exceeds 105% of the aggregate amount
      of LC Exposure, as of such date, then (i) the Collateral Agent shall, upon
      any
      request therefor from the Company, direct the Depository Bank to transfer such
      excess of funds on deposit in the Cash Collateral Account (any such amount,
      “Unused Cash Collateral”) into the Collateral Account; and (ii)
      such Unused Cash Collateral shall be applied in accordance with Section 2.09
      of
      the Credit Agreement and Section 6.02.

     

    Section
      4.03.  Qualified
      Investments Account. (a) If a FERC-Regulated Restricted Subsidiary receives
      Net Cash Proceeds from the Disposition of a Covered Asset as described in clause
      (d) of the definition of “Mandatory Asset Reduction Event”, then the Company
      shall deposit, or cause to be deposited, into the Collateral Account, within
      five days after such receipt, the amount, if any, by which the portion of such
      Net Cash Proceeds that is not deemed to have been invested in Qualified
      Investments described in clause (a)(ii) or (a)(iii) of the definition thereof
      exceeds $100,000,000.

     

    (b)  If
      an Unregulated
      Restricted Subsidiary receives Net Cash Proceeds from the Disposition of a
      Covered Asset as described in clause (d) of the definition of “Mandatory Asset
      Reduction Event”, then the Company shall deposit, or cause to be deposited, into
      the Collateral Account, within five days after such receipt, the portion of
      such
      Net Cash Proceeds that is not deemed to have been invested in Qualified
      Investments described in clause (b)(ii) or (b)(iii) of the definition
      thereof.

     

    (c)  So
      long as no Event
      of Default has occurred and is continuing within one Business Day after receipt,
      the Collateral Agent shall direct the Depository Bank to transfer the funds
      deposited into the Collateral Account pursuant to Section 4.03(a) or 4.03(b)
      (in either case, for each Disposition, the “Remaining Reinvestment
      Amount”) to the Qualified Investments Account.

     

    (d)  If
      funds are to be
      transferred to the Qualified Investments Account pursuant to Section 4.03(c) and after giving effect to such
      transfer the Qualified Investments Account would contain funds in respect of
      the
      Covered Assets of more than one Restricted Subsidiary, or in respect of more
      than one Covered Asset of a single Restricted Subsidiary, the Collateral Agent
      shall cause the Depository Bank to establish and maintain individual securities
      subaccounts, or the Collateral Agent shall establish in its accounting records
      notional subaccounts (each, a “Qualified Investments
      Subaccount”), in each case within the Qualified Investments Account,
      for each such Restricted Subsidiary or each such Covered Asset.

     

    (e)  For
      the period from
      the initial transfer of the Remaining Reinvestment Amount to the Qualified
      Investments Account, until the date, if ever, on which the failure of the
      applicable Restricted Subsidiary to invest such Remaining Reinvestment Amount
      in
      Qualified Investments, requires application of all or a portion thereof in
      connection with a reduction of the Commitments pursuant to Section 2.07(d)
      of
      the Credit Agreement, the Collateral Agent shall, at the written direction
      of
      the Company from time to time, direct the Depository Bank to pay such funds
      on
      deposit in the Qualified Investments Account (or any applicable Qualified
      Investments Subaccount) to the Restricted Subsidiary identified by the Company
      in the Officer’s Certificate described in the following sentence.  The
      written direction described in the preceding sentence shall be accompanied
      by an
      Officer’s Certificate (i) setting forth the name of the Restricted Subsidiary
      whose Disposition of Covered Assets resulted in the deposit of the Remaining
      Reinvestment Amount that is being requested to be paid pursuant to such written
      direction, (ii) if such Restricted Subsidiary is a FERC-Regulated Restricted
      Subsidiary, stating that all funds retained by such FERC-Regulated Restricted
      Subsidiary pursuant to Section 4.03(a) from
      the Net Cash Proceeds of all of its Dispositions of Covered Assets prior to
      the
      date of such certificate have been, or (by making the currently proposed
      Qualified Investment(s)) will be, used to make Qualified Investments, and (iii)
      describing the Qualified Investment(s) to be made (or deemed made) by such
      Restricted Subsidiary with such funds, pursuant to the definition of “Qualified
      Investment”.  Notwithstanding the foregoing, the Company shall have
      the right to direct that funds on deposit in the Qualified Investments Account
      or any applicable Qualified Investments Subaccount be paid to a FERC-Regulated
      Restricted Subsidiary in respect of new Qualified Investments made or deemed
      made by such FERC-Regulated Restricted Subsidiary only if, on the proposed
      date
      of such payment from the Qualified Investments Account or applicable Qualified
      Investments Subaccount, the aggregate amount of Qualified Investments made
      by
      such FERC-Regulated Restricted Subsidiary after April 16, 2003 equals or exceeds
      the sum of (1) the product of (x) $100,000,000 times (y) the number of such
      Dispositions of Covered Assets by such FERC-Regulated Restricted Subsidiary
      that
      have resulted in a deposit in the Collateral Account, plus (2) the aggregate
      Net
      Cash Proceeds of Dispositions of Covered Assets by such FERC-Regulated
      Restricted Subsidiary after April 16, 2003 that have not resulted in deposits
      into the Collateral Account.

     

    (f)  If
      a Mandatory
      Asset Reduction Event described in clause (d) of the definition thereof shall
      occur with the result that the Company is required to cause Loans to be prepaid
      or Letters of Credit to be Cash Collateralized pursuant to Section 2.09(c)
      of
      the Credit Agreement (a “2.09 Application”), the Collateral
      Agent shall direct the Depository Bank to transfer (i) if such Mandatory Asset
      Reduction Event does not occur during the pendency of an Event of Default,
      (A)
      an amount equal to the lesser of (x) the required 2.09 Application and (y)
      80%
      of the funds remaining in the Qualified Investments Account (or the applicable
      Qualified Investments Subaccount) in respect of the applicable Disposition
      of
      Covered Assets to the Collateral Account to be applied in accordance with
      Section 2.09(c) of the Credit Agreement, and (B) any remaining funds in the
      Qualified Investments Account (or the applicable Qualified Investments
      Subaccount) to the Company, or as the Company directs, to be used for general
      corporate purposes, or (ii) if such Mandatory Asset Reduction Event occurs
      concurrently with or during the pendency of an Event of Default, 100% of the
      funds remaining in the Qualified Investments Account (and in all applicable
      Qualified Investments Subaccounts) in respect of the applicable Disposition
      of
      Covered Assets to the Collateral Account to be applied (x) to the extent of
      the
      required 2.09 Application, in accordance with Section 2.09(c) of the Credit
      Agreement and (y) the balance, in accordance with Section 6.02 hereof.

     

    (g)  If
      following the
      application of a Mandatory Asset Reduction Amount in accordance with Section
      2.07(d) of the Credit Agreement and any prepayment of Loans or Cash
      Collateralization of outstanding Letters of Credit in connection therewith
      pursuant to Section 2.09(c) of the Credit Agreement, there are remaining funds
      in the Qualified Investments Account attributable to such Mandatory Asset
      Reduction Amount, the Collateral Agent shall direct the Depository Bank to
      transfer such remaining funds (i) if no Event of Default exists at the time,
      to
      the Company, or as the Company directs, to be used for general corporate
      purposes, or (ii) if an Event of Default exists at the time, to the Collateral
      Account to be applied in accordance with Section
      6.02 hereof.

     

    (h)  The
      Collateral
      Agent shall effectuate any transfer required pursuant to Section
      4.03(f)
      or
4.03(g)
      by giving appropriate entitlement orders to the Depository Bank.

      in Trust.  If, notwithstanding the instructions given or required
      to be given in accordance with this Article
      4, any payments required by any Security Document to be remitted
      to
      the Collateral Agent are instead remitted to the Company or its Affiliates
      (it
      being the intent and understanding of the parties hereto that such payments
      are
      not to be made directly to the Company but directly to the Collateral Agent
      for
      deposit into, or credit to, the relevant Pledged Account for application in
      accordance with this Article
      4), then, to the fullest extent permitted by Applicable Law, the
      Company or such other Person shall receive such payments into a constructive
      trust for the benefit of the Secured Parties and subject to the Secured Parties’
security interest, and shall (or shall use its best efforts to cause the Person
      receiving such payments to) promptly remit them to the Collateral Agent for
      deposit into, or credit to, the applicable Pledged Account designated by this
Article
      4.

     

    Section
      4.05.  Investment
      of Funds in Pledged Accounts.  (a) The Collateral
      Agent will promptly direct the Depository Bank to (i) invest amounts on deposit
      in, or credited to, the Pledged Accounts, (ii) reinvest any interest paid on
      the
      amounts referred to in clause (i) above, and (iii)
      reinvest other proceeds of any such amounts that may mature or be sold, in
      each
      case, in Cash Equivalents which are deposited into, or credited to, such Pledged
      Account, in each case as the Company may select and instruct the Collateral
      Agent, unless, to the knowledge of the Collateral Agent, any Event of Default
      has occurred and is continuing, in which event the Collateral Agent shall direct
      the Depository Bank to invest such amounts in Cash Equivalents as the Collateral
      Agent may direct.  If no Event of Default then exists, interest and
      proceeds resulting from an investment of funds in any Pledged Account in Cash
      Equivalents shall be, promptly upon request of the Company, transferred to
      the
      Company to be used for general corporate purposes.  In addition,
      subject to any instructions from the Company (if not during the pendency of
      an
      Event of Default), the Collateral Agent shall have the right at any time to
      direct the Depository Bank to exchange such Cash Equivalents for similar Cash
      Equivalents of smaller or larger denominations.

     

    (b)  Unless
      it has
      received instructions from the Company in accordance with this Section 4.05 as to the investment of such funds, the
      Collateral Agent may direct the Depository Bank to invest or reinvest any funds
      in any Pledged Account.  All investments and reinvestments of funds in
      the Pledged Accounts shall be made in the name of the Depository
      Bank.

     

    (c)  Whenever
      directed
      to make a transfer of funds from any of the Pledged Accounts in accordance
      with
      this Article
      4, the Collateral Agent is hereby directed and authorized by the
      Company, the Borrowers and the Grantors (for themselves and their respective
      Subsidiaries) to direct the Depository Bank to liquidate (or cause to be
      liquidated) Cash Equivalents (in order of their respective maturities with
      the
      Cash Equivalents with the shortest maturities being liquidated first), to the
      extent that, after application of all other funds available for such purpose
      pursuant to this Article
      4, the liquidation of any Cash Equivalent is necessary to make such
      transfer.

     

    (d)  Neither
      the
      Collateral Agent nor the Depository Bank shall (in the absence of gross
      negligence or willful misconduct, as finally determined by a court of competent
      jurisdiction) have any liability with respect to any interest, cost or penalty
      on the liquidation of any Cash Equivalent pursuant to this Agreement, nor shall
      the Collateral Agent (in the absence of gross negligence or willful misconduct,
      as finally determined by a court of competent jurisdiction) have any liability
      with respect to Cash Equivalents (including purchases or conversions of foreign
      exchange) or moneys deposited into, or credited to, the Pledged Accounts (or
      any
      losses resulting therefrom) invested in accordance with this Agreement. Without
      limiting the generality of the foregoing, in the absence of gross negligence
      or
      willful misconduct, as finally determined by a court of competent jurisdiction,
      the Collateral Agent shall have no responsibility for any investment losses
      resulting from the investment, reinvestment or liquidation of all or a portion
      of funds in the Pledged Accounts, if the Collateral Agent has made such
      investment, reinvestment or liquidation, as applicable, in accordance with
      this
      Agreement.

     

    (e)  All
      references in
      this Agreement to Pledged Accounts and to cash, moneys or funds therein or
      balances thereof, shall include the Cash Equivalents in which such cash, moneys,
      funds or balances are then invested and the proceeds thereof, and all financial
      assets and security entitlements carried in or credited to such Pledged
      Accounts.

     

    (f)  (i)
      Neither the
      Collateral Agent nor any of its Affiliates assume any duty or liability for
      monitoring the rating or performance of any Cash Equivalent.  Subject
      to Section 4.06, in the event an investment
      selection is not made by the Company in accordance with this Section 4.05, the funds in the Pledged Accounts shall
      not be required to be invested but may be invested at the discretion of the
      Collateral Agent, and the Collateral Agent shall not incur any liability for
      interest or income thereon.  The Collateral Agent shall have no
      obligation to cause the investment or reinvestment of the funds in the Pledged
      Accounts on the day of deposit if all or a portion of such funds is deposited
      with the Collateral Agent after 11:00 a.m. (New York City time) on such day
      of
      deposit.  Instructions to invest or reinvest that are received after
      11:00 a.m. (New York City time) will be treated as if received on the following
      Business Day in New York.  Requests or instructions received after
      11:00 a.m. (New York City time) by the Collateral Agent to liquidate all or
      a
      portion of funds in any Pledged Account will be treated as if received on the
      following Business Day in New York.

     

    (ii)  The
      Credit Parties
      acknowledge that non-deposit investment products (A) are not obligations of,
      nor
      guaranteed, by JPMCB or any of its Affiliates; (B) are not FDIC insured; and
      (C)
      are subject to investment risks, including the possible loss of principal amount
      invested.

     

    Section
      4.06.  Transfers
      from Accounts During the Continuance of an Event of
      Default.  During the existence and continuance of an Event of
      Default, the Collateral Agent shall not be obligated to accept any instructions
      from the Company with respect to any transfer or withdrawal of funds on deposit
      in, or credited to, any Pledged Account and, in such circumstances, the
      Collateral Agent may direct the investment, transfer or withdrawal of funds
      in
      the Pledged Accounts without further consent by the Company.

     

    Section
      4.07.  Reports,
      Certification and Instructions.  (a) The Collateral Agent shall
      maintain all such accounts, books and records as may be necessary to properly
      record all transactions carried out by it under this Agreement.  The
      Collateral Agent shall permit the Company and its Affiliates and their
      authorized representatives to examine such accounts, books and records;
provided that any such examination shall occur upon reasonable notice
      and during normal business hours.

     

    (b)  The
      Collateral
      Agent shall deliver to the Company copies of the account statements for all
      Pledged Accounts (including all subaccounts) for each month.  Such
      account statements shall indicate, with respect to each such account, deposits,
      credits and transfers, investments made and closing balances.  The
      Collateral Agent shall provide any additional information or reports relating
      to
      the Pledged Accounts and the transactions therein reasonably requested from
      time
      to time by the Company or any Secured Party.

     

    (c)  Each
      time the
      Company directs the Collateral Agent to make or cause to be made a transfer
      or
      withdrawal from a Pledged Account, it shall be deemed to represent and warrant
      for the benefit of the Collateral Agent and the other Secured Parties that
      such
      transfer or withdrawal is being made in an amount, and shall be applied solely
      for the purposes permitted by, and is and will otherwise be in accordance with,
      this Agreement and the Credit Agreement.  Except to the extent any
      officer or officers of the Collateral Agent responsible for the administration
      of this Agreement has actual knowledge to the contrary, the Collateral Agent
      may
      conclusively rely on, and shall incur no liability in so relying on, any such
      direction.

     

    (d)  Notwithstanding
      any
      provision to the contrary contained in this Agreement, all notices,
      certifications, approvals, directions, instructions or other communication
      given
      to the Collateral Agent with respect to any payments, transfers, credits,
      deposits, withdrawals or investments with respect to, or otherwise relating
      to,
      any Pledged Account, in each case, by the Company or by any other Secured Party
      shall be given in writing, and the Collateral Agent shall not be required to
      take any action with respect to any payments, transfers, credits, deposits,
      withdrawals or investments unless it has received such written instructions
      specifying the date, amount and Pledged Account with respect to which such
      payment, transfer, credit, deposit, withdrawal or investment is to be
      made.

     

    Section
      4.08.  Depository
      Bank Undertakings.  The Depository Bank hereby represents and
      warrants to, and agrees with the Company and the Collateral Agent as
      follows:

     

    (a)  The
      Depository Bank
      (i) is a securities intermediary on the date hereof and (ii) so long as this
      Agreement remains in effect and such Depository Bank remains the Depository
      Bank
      hereunder, shall remain a securities intermediary, and shall act as such with
      respect to the Company, the Collateral Agent, the Pledged Accounts and all
      of
      the Account Collateral and any other property (including all financial assets
      and security entitlements maintained or carried in the Pledged Accounts) from
      time to time transferred to, credited to, deposited in, or maintained in the
      Pledged Accounts.

     

    (b)  Each
      of the Pledged
      Accounts is, and shall remain, and the Depository Bank shall maintain each
      of
      the Pledged Accounts as, a securities account, with the Collateral Agent (and
      no
      other Person) as the entitlement holder and under the sole dominion and control
      of the Collateral Agent for the ratable benefit of the Collateral Agent and
      the
      other Secured Parties.

     

    (c)  The
      Depository Bank
      (i) has identified (and will continue to identify) the Collateral Agent for
      the
      ratable benefit of the Secured Parties in its records as, and will treat the
      Collateral Agent as (A) the sole Person having a security entitlement against
      the Depository Bank with respect to the Pledged Accounts and the Account
      Collateral from time to time carried in the Pledged Accounts, (B) the sole
      entitlement holder against the Depository Bank with respect to each of the
      Pledged Accounts, (C) the sole Person having dominion and control over each
      of
      the Pledged Accounts and any and all assets, property and items from time to
      time carried in such Pledged Accounts (including cash) and (D) the sole Person
      entitled to exercise the rights with respect to the Pledged Accounts; and (ii)
      has credited and will continue to credit such assets, property and items to
      the
      Pledged Accounts in accordance with written instructions given pursuant to, and
      the other terms and conditions of, this Agreement.

     

    (d)  All
      of the
      property, including Account Collateral and cash, from time to time carried
      in or
      credited to the Pledged Accounts, shall constitute financial assets, and the
      Depository Bank shall treat all such property as financial assets under Article
      8 of the UCC.

     

    (e)  Notwithstanding
      any
      other provision in this Agreement to the contrary, the Depository Bank (i)
      shall
      comply with any and all entitlement orders and other directions originated
      by,
      and only by, the Collateral Agent in respect of the Pledged Accounts and the
      Account Collateral from time to time carried therein without any further consent
      or action by the Company or any other Person and (ii) shall not comply with
      the
      entitlement orders of any other Person.

     

    (f)  The
“securities
      intermediary’s jurisdiction” (within the meaning of Section 8-110(e) of the UCC)
      of the Depository Bank is and will continue to be the State of New
      York.

     

    (g)  To
      be binding on
      the Depository Bank, all instructions by the Collateral Agent pursuant to this
      Agreement with respect to the Account Collateral carried in the Pledged Accounts
      must be given to the Depository Bank, and only pursuant to and subject to the
      terms and conditions of this Agreement.

     

    (h)  Anything
      herein to
      the contrary notwithstanding, the Depository Bank will not be required to follow
      any instruction that would violate any Applicable Law, decree, regulation or
      order of any Governmental Authority (including any court or tribunal) or the
      terms of this Agreement.

     

    (i)  The
      Depository Bank
      has not entered into and will not enter into any agreement with any other Person
      relating to the Pledged Accounts or any Pledged Financial Assets credited
      thereto pursuant to which it has agreed or will agree to comply with entitlement
      orders of such Person.  The Depository Bank has not entered into any
      other agreement with the Company or any other Person purporting to limit or
      condition the duties of the Depository Bank to comply with entitlement orders
      originated by the Collateral Agent as set forth in Section 4.08(e).

     

    (j)  The
      Depository Bank
      hereby permanently waives and releases any Lien, right of setoff or other right
      it may have against the Pledged Accounts and any Pledged Financial Assets or
      Pledged Security Entitlements carried in or credited to the Pledged Accounts
      and
      any credit balance or cash in the Pledged Accounts, and agrees that it will
      not
      assert any such Lien or other right in, to or against the Pledged Accounts
      or
      any Pledged Financial Asset or Pledged Security Entitlement carried therein
      or
      credited thereto, or any credit balance or cash in the Pledged
      Accounts.

     

    (k)  The
      Depository Bank
      will send copies of all statements and confirmations for and in respect of
      the
      Pledged Accounts simultaneously to the Company and the Collateral
      Agent.

     

    (l)  All
      securities or
      other property underlying any financial assets consisting of Account Collateral
      deposited in or credited to a Pledged Account shall be registered in the name
      of
      the Depository Bank, endorsed to the Depository Bank or in blank or credited
      to
      another securities account or securities accounts maintained in the name of
      the
      Depository Bank, and in no case will any financial asset consisting of Account
      Collateral deposited in or credited to a Pledged Account be registered in the
      name of the Company, payable to the order of the Company or specially endorsed
      to the Company, except to the extent the foregoing have been specially endorsed
      by the Company to the Depository Bank or in blank.

     

    (m)  If
      any Person
      (other than the Collateral Agent) asserts to the Depository Bank any Lien,
      encumbrance or adverse claim (including any writ, garnishment, judgment, warrant
      of attachment, execution or similar process) against any Account Collateral,
      the
      Depository Bank will as promptly as practicable thereafter notify the Company
      and the Collateral Agent thereof.

     

    Section
      4.09.  Force
      Majeure.  Neither the Collateral Agent nor the Depository Bank
      shall incur any liability for not performing any act or fulfilling any
      obligation hereunder by reason of any occurrence beyond its control (including
      any provision of any present or future law or regulation or any act of any
      Governmental Authority, any act of God, war or terrorism, or the unavailability
      of the Federal Reserve Bank wire services or any electronic communication
      facility).

     

    Section
      4.10.  Clearing
      Agency.  The Account Collateral in the Pledged Accounts may be
      held by the Collateral Agent directly or through any clearing agency or
      depository including the Federal Reserve/Treasury Book-Entry System for United
      States and federal agency securities, and the Depository Trust Company
      (collectively, the “Clearing Agency”).  The
      Collateral Agent shall not have any responsibility or liability for the actions
      or omissions to act on the part of any Clearing Agency.  The
      Collateral Agent is authorized, for any Collateral at any time held hereunder,
      to register the Collateral in the name of one or more of its nominee(s) or
      the
      nominee(s) of any Clearing Agency in which the Collateral Agent has a
      participant account, and such nominee(s) may sign the name of any Credit Party
      and guarantee such signature in order to transfer securities or certify
      ownership thereof to tax or other Governmental Authorities.

     

    Section
      4.11.  Return
      of Funds to the Company.  Upon any request by the Company
      following the release of the Transaction Liens in accordance with Section 5.07(b), the Collateral Agent shall direct the
      Depository Bank to, and the Depository Bank shall promptly pay, transfer and
      deliver to or to the order of the Company all moneys, investments, and other
      property held in, or credited to, the Pledged Accounts, in each case, in
      accordance with the instructions of the Company and at the Company’s
      expense.

      created under this Section 5.01(c) shall not
      encumber, any Excluded Payment Property of the Company.

     

    (d)  Each
      Grantor hereby
      grants to the Collateral Agent, for the ratable benefit of the Secured Parties,
      a security interest in such Grantor’s right, title and interest in and to the
      following, in each case, as to each type of property described below, whether
      now owned or hereafter acquired by such Grantor, wherever located, and whether
      now owned or hereafter existing or arising (collectively, the “Account
      Collateral”):

     

    (i)  the
      Pledged
      Accounts, all Pledged Financial Assets, all Pledged Security Entitlements and
      all property, funds, interest, dividends, distributions, cash, instruments
      and
      other property from time to time carried in or credited to any Pledged Account
      or received, receivable or otherwise distributed in respect of or in exchange
      for any or all of the foregoing, and all certificates and instruments, if any,
      from time to time representing or evidencing the Pledged Accounts;

     

    (ii)  all
      promissory
      notes, certificates of deposit, deposit accounts, checks and other instruments
      delivered (or required to be delivered) to or otherwise possessed by the
      Collateral Agent for or on behalf of such Grantor in connection with the Account
      Collateral, including those received in substitution for or in addition to
      any
      or all of the Account Collateral;

     

    (iii)  all
      interest,
      dividends, distributions, cash, instruments and other property from time to
      time
      received, receivable or otherwise distributed in respect of or in exchange
      for
      any or all of the Account Collateral;

     

    (iv)  all
      books and
      records of such Grantor pertaining to any of the Account
      Collateral;

     

    (v)  all
      supporting
      obligations, general intangibles, contract rights, warranties, indemnities
      and
      guaranties, in each case to the extent relating to, or payable in respect of,
      the Account Collateral; and

     

    (vi)  all
      proceeds of the
      foregoing Account Collateral.

     

    Section
      5.02.  Security
      for Obligations.  (a)  In the case of each Grantor,
      the security interests granted by such Grantor pursuant to Sections 5.01(a)
      through (d) secure the payment and performance of all such Grantor’s Secured
      Obligations, whether now existing or hereafter arising.

     

    (b)  Without
      limiting
      the generality of subsection (a) of this Section
      5.02, as to each Grantor, the security interests granted by such
      Grantor pursuant to Sections 5.01(a) through (d) secure the payment of all
      amounts that constitute part of such Grantor’s Secured Obligations and would be
      owed by such Grantor but for the fact they are unenforceable or not allowable
      due to the existence of an Insolvency Proceeding involving such
      Grantor.

     

    Section
      5.03.  Delivery
      and Control of Collateral.  (a) All certificates or instruments
      representing or evidencing Security Collateral shall be delivered to and held
      by
      or on behalf of the Collateral Agent pursuant hereto and shall be in suitable
      form for transfer by delivery, or shall be accompanied by duly indorsed
      instruments of transfer or assignment in blank, all in form and substance
      reasonably satisfactory to the Collateral Agent, but excluding checks,
      certificates of title and other similar instruments.  If an Event of
      Default has occurred and is continuing, the Collateral Agent shall have the
      right, in its discretion and without notice to any Credit Party, to transfer
      to
      or to register in the name of the Collateral Agent or any of its nominees any
      or
      all of the Security Collateral, subject only to the revocable rights specified
      in Section 5.08.  In addition, the
      Collateral Agent shall have the right at any time to exchange certificates
      or
      instruments representing or evidencing Security Collateral for certificates
      or
      instruments of smaller or larger denominations.

     

    (b)  With
      respect to any
      Security Collateral in which any Grantor has any right, title or interest and
      that constitutes an uncertificated security, such Grantor will cause the issuer
      thereof to agree in an authenticated record with such Grantor and the Collateral
      Agent that such issuer will comply with instructions with respect to such
      Security Collateral originated by the Collateral Agent without further consent
      of such Grantor, such authenticated record to be in form and substance
      satisfactory to, and to be delivered to, the Collateral Agent.  With
      respect to any Security Collateral in which any Grantor has any right, title
      or
      interest and that is not an uncertificated security, upon the request of the
      Collateral Agent, such Grantor will notify each such issuer of Pledged Equity
      that such Pledged Equity is subject to the security interest granted
      hereunder.

     

    (c)  Each
      Grantor shall
      deliver to the Collateral Agent all Payment Collateral pledged by it that
      constitutes instruments or tangible chattel paper, accompanied by duly indorsed
      instruments of transfer or assignment in blank, which instruments of transfer
      or
      assignment shall be in form reasonably satisfactory to the Collateral
      Agent.

     

    Section
      5.04.  Further
      Assurances; Etc..  (a) Each Grantor agrees that from time to
      time, at the expense of such Grantor, such Grantor will promptly do, execute,
      acknowledge, deliver, record, re-record, file, re-file, register and re-register
      any and all such further acts, pledge agreements, collateral assignments,
      account control agreements, financing statements and continuations thereof,
      termination statements, notices of assignment, transfers, certificates,
      assurances and other instruments as the Collateral Agent or the Depository
      Bank
      may reasonably require from time to time in order to (i) carry out more
      effectively the purposes of the Security Documents with respect to the
      Collateral, (ii) to the fullest extent permitted by Applicable Law, subject
      its
      right, title and interest in and to the Collateral to the Transaction Liens,
      (iii) perfect and maintain the validity and effectiveness of the Security
      Documents and the validity, effectiveness and priority of the Transaction Liens
      and (iv) assure, grant, collaterally assign, transfer, preserve, protect and
      confirm more effectively unto the Secured Parties the rights granted or now
      or
      hereafter stated to be granted to the Secured Parties in respect of the
      Collateral under any Security Document or under any other instrument executed
      in
      connection with any Security Document to which it is a party.  Without
      limiting the generality of the foregoing, each Grantor will promptly with
      respect to Collateral of such Grantor:  (A) execute or authenticate
      and file such financing or continuation statements, or amendments thereto,
      and
      such other instruments or notices, as may be necessary or desirable, or as
      the
      Collateral Agent may reasonably request, in order to perfect and preserve the
      Transaction Liens; (B) deliver and pledge to the Collateral Agent for benefit
      of
      the Secured Parties certificates representing Security Collateral that
      constitutes certificated securities, accompanied by undated stock powers
      indorsed in blank, and deliver and pledge to the Collateral Agent for the
      benefit of the Secured Parties all tangible chattel paper and all instruments
      constituting Collateral, together with duly indorsed instruments of transfer
      or
      assignment in blank; (C) take all action necessary to ensure that the Collateral
      Agent has control of Collateral, if any, consisting of deposit accounts, as
      provided in Section 9-104 of the UCC, control of the Account Collateral as
      provided in Sections 8-106 and 9-106 of the UCC, and control of Payment
      Collateral consisting of electronic chattel paper as provided in Section 9-105
      of the UCC; and (D) deliver to the Collateral Agent evidence that all other
      action that the Collateral Agent may reasonably request as necessary or
      desirable to perfect and preserve Transaction Liens has been taken.

     

    (b)  Each
      Grantor hereby
      authorizes the Collateral Agent to file one or more financing or continuation
      statements, and amendments thereto, including one or more financing statements
      indicating that such financing statements cover all right, title and interest
      of
      such Grantor in and to the Collateral, in each case without the signature of
      such Grantor.  The Collateral Agent shall provide a copy of each such
      financing statement to each Grantor.  A photocopy or other
      reproduction of this Agreement or any financing statement covering the
      Collateral or any part thereof shall be sufficient as a financing statement
      where permitted by law.  Each Grantor ratifies its authorization for
      the Collateral Agent to have filed such financing statements, continuation
      statements or amendments filed prior to the date hereof.

     

    Section
      5.05 .  Grantors
      Remain Liable.  Anything herein to the contrary notwithstanding,
      (a) each Grantor shall remain liable under any contracts and agreements included
      in such Grantor’s Collateral (including, with respect to Security Collateral,
      any obligations under limited liability company agreements, limited partnership
      agreements and any other organizational or constituent documents pursuant to
      which Pledged Equity has been issued or which sets out obligations with respect
      to Security Collateral) to the extent set forth therein to perform all of its
      duties and obligations thereunder to the same extent as if this Agreement had
      not been executed, (b) the exercise by the Collateral Agent of any of the rights
      hereunder shall not release any Grantor from any of its duties or obligations
      under the contracts and agreements included in the Collateral and (c) no Secured
      Party shall have any obligation or liability under the contracts and agreements
      included in the Collateral by reason of this Agreement or any other Security
      Document, nor shall any Secured Party be obligated to perform any of the
      obligations or duties of any Grantor thereunder or to take any action to collect
      or enforce any claim for payment assigned hereunder.

     

    Section
      5.06.  Additional
      Equity Interests.  (a)  Pledged
      Equity.  Each Grantor agrees that (i) it will cause each Pledged
      Company the Pledged Equity in which has been pledged by such Grantor hereunder,
      not to issue any Equity Interests or other securities in addition to or in
      substitution for the Pledged Equity issued by such Pledged Company, except
      to
      such Grantor, (ii) it will pledge hereunder, immediately upon such Grantor’s
      acquisition (directly or indirectly) thereof, any and all additional Equity
      Interests issued by such Pledged Company, and (iii) it will cause all such
      Equity Interests issued by such Pledged Company to be certificated securities
      under Article 8 of the UCC and under Article 8 or Chapter 8 of the Uniform
      Commercial Code as in effect in the jurisdiction of organization of such Pledged
      Company; provided, however, that this Section
      5.06 shall not limit any Grantor’s rights under Section 5.07(a)(ii).

     

    (b)  Ownership
      of
      Equity Interests in Grantors.  The Company agrees and covenants
      that it will at all times own, directly or indirectly, 100% of the outstanding
      Equity Interests (including all voting, economic and other rights associated
      therewith) in each Grantor, except for the rights of the Collateral Agent
      hereunder with respect to the Equity Interests in any Grantor that is a Pledged
      Company.

     

    (c)  Ownership
      of
      Equity Interests in Pledged Companies.  Each Grantor (including
      any successor thereto pursuant to a merger or consolidation permitted under
      Section 6.05 of the Credit Agreement) agrees and covenants that (i) it will
      at
      all times remain a registered organization, as defined in Section 9-102(70)
      of
      the UCC, and (ii) with respect to each Pledged Company in which such Grantor
      has
      pledged Equity Interests hereunder, such Grantor will at all times own directly
      100% of the outstanding Equity Interests issued by such Pledged Company
      (including voting, economic and other rights associated therewith), except
      to
      the extent permitted under Section 6.04(a)(iv) of the Credit Agreement and
      except for the rights of the Collateral Agent hereunder.

     

    Section
      5.07.  Release
      of Collateral. (a) Partial Release of Collateral.

     

    (i)  Payments
      out of
      Pledged Accounts.  Upon any payment of amounts out of any Pledged
      Account (and not deposited into, or transferred to, another Pledged Account)
      to
      (A) the Administrative Agent, the Collateral Agent or the Depository Bank in
      respect of amounts due and payable hereunder to such Persons or other Secured
      Parties, (B) any Secured Party or (C) the Company or any Restricted Subsidiary
      (or any other Person designated in writing by the Company to the Collateral
      Agent to receive such payment), in each case in accordance with the Security
      Documents, the Transaction Liens on such amount shall be automatically released
      without further action or consent by the Collateral Agent or any other Person
      (including any Secured Party).

     

    (ii)  Release
      of Lien
      on Collateral.  Upon the Disposition of any Collateral in a
      transaction permitted under the Credit Agreement and the other Loan Documents,
      the Transaction Liens on such Collateral shall be automatically released without
      further action or consent by the Collateral Agent or any other Person (including
      any other Secured Party).

     

    (b)  Full
      Release of
      Collateral.  On the earlier of (A) the Final Payment Date or (B)
      the date on which the requisite percentage of the Lenders have approved the
      release of the Transaction Liens in accordance with Section 10.02 of the Credit
      Agreement, the Transaction Liens shall be fully and automatically released
      without further action by the Collateral Agent or any other Person (including
      any other Secured Party), and all rights to the Collateral shall revert to
      the
      applicable Grantor.

     

    (c)  Delivery
      of
      Releases and Return of Collateral.  Upon the release of any
      Transaction Lien pursuant to this Section 5.07, the
      Collateral Agent will, at the applicable Grantor’s expense, (i) execute and
      deliver to such Grantor such release or releases (including Uniform Commercial
      Code partial release or termination statements) as such Grantor shall reasonably
      request to evidence such release, and (ii) deliver to the applicable Grantors
      or
      their designees designated in writing to the Collateral Agent such Collateral,
      including any Assets in the Pledged Accounts and any certificates or instruments
      representing or evidencing any such Collateral that is Security
      Collateral.

     

    Section
      5.08.  Voting
      Rights, Dividends, Payments, Etc.  (a) So long as no Event of
      Default shall have occurred and be continuing:

     

    (i)  each
      Grantor shall
      be entitled to exercise any and all voting and other consensual rights
      pertaining to the Security Collateral (including rights relating to conversion
      or exchange thereof) of such Grantor or any part thereof at any time and for
      any
      purpose; provided that such Grantor will not exercise or refrain from
      exercising any such right if such action would violate this
      Agreement;

     

    (ii)  except
      as provided
      in Section 5.08(b), each Grantor shall be entitled
      to receive and retain any and all cash dividends, interest and other cash
      distributions paid in respect of the Security Collateral of such
      Grantor;

     

    (iii)  each
      Grantor shall
      be entitled to receive and retain all payments made on or in respect of Payment
      Collateral pledged by such Grantor; and

     

    (iv)  the
      Collateral
      Agent will (A) execute and deliver (or cause to be executed and delivered)
      to
      each Grantor all such proxies and other instruments as such Grantor may
      reasonably request for the purpose of enabling such Grantor to exercise the
      voting and other rights that it is entitled to exercise pursuant to paragraph
(i) above (including, in the case of a conversion
      or
      exchange of Pledged Equity, the Collateral Agent’s delivering to the Pledged
      Company, as applicable, on behalf of the applicable Grantor, the certificate(s)
      or instrument(s) representing or evidencing any such Collateral for the purpose
      of effecting the exchange of such certificate(s) or instrument(s) for new
      certificate(s) or instrument(s)) and to receive the dividends, interest or
      other
      distributions that it is authorized to receive and retain pursuant to paragraph
      (ii) above, and (B) with respect to Payment
      Collateral, provide such instructions to account debtors and Persons obligated
      to make payments on instruments as will enable each Grantor to receive all
      payments it is authorized to receive and retain pursuant to paragraph (iii) above.  In the absence of instructions
      to vote or exercise other rights, the Collateral Agent shall not be obligated
      and shall incur no liability for its failure to take any action in respect
      of
      such rights.

     

    (b)  The
      Collateral
      Agent shall be entitled to receive (whether or not an Event of Default has
      occurred and is continuing), (i) all non-cash dividends and distributions
      (including distributions upon conversion or exchange of Security Collateral)
      paid in respect of Security Collateral, which shall be held by the Collateral
      Agent as Security Collateral, and (ii) all cash dividends, interest and other
      cash distributions in respect of Security Collateral distributed in exchange
      for, in redemption of, or in connection with a partial or total liquidation
      or
      dissolution or with a reduction of capital, capital surplus or paid-in-surplus,
      which distributions described in this clause (ii)
      shall be deposited in the Collateral Account and held and administered as
      Account Collateral, provided, however, that a Credit Related Party that
      receives a dividend from a FERC-Regulated Restricted Subsidiary shall not be
      required to deliver such funds to the Collateral Agent so long as (x) such
      funds
      are not proceeds of a Mandatory Asset Reduction Event and (y) such funds are
      otherwise transferred to the Company.  Each issuer of Pledged Equity
      that is a party to this Agreement agrees to pay and deliver all dividends,
      distributions and interest described in this Section
      5.08(b) on such Pledged Equity directly to the Collateral
      Agent.  With respect to any Pledged Equity issued in conversion or
      exchange of Pledged Equity issued by an issuer that is not a Pledged Company,
      the Grantor that has pledged such Pledged Equity shall instruct the issuer
      to
      deliver directly to the Collateral Agent the Pledged Equity so issued in the
      exchange or conversion.  Any and all dividends, distributions and
      interest described in this Section 5.08(b) that are
      received by a Grantor contrary to the provisions of this Section 5.08(b), shall be received in trust for the
      benefit of the Collateral Agent, shall be segregated from the other property
      or
      funds of such Grantor, and shall promptly be delivered or paid over to the
      Collateral Agent and held and administered as above provided in this Section 5.08(b).

     

    (c)  Upon
      the occurrence
      and during the continuance of any Event of Default:

     

    (i)  all
      rights of each
      Grantor to exercise or refrain from exercising the voting and other consensual
      rights that it would otherwise be entitled to exercise pursuant to Section 5.08(a)(i) shall, upon delivery by the
      Collateral Agent to such Grantor of a written notice of such Event of Default,
      cease, and all such rights shall thereupon become vested in the Collateral
      Agent, which shall thereupon have the sole right to exercise or refrain from
      exercising such voting and other consensual rights;

     

    (ii)  all
      rights of each
      Grantor to receive the dividends, interest and other distributions that it
      would
      otherwise be authorized to receive and retain pursuant to Section 5.08(a)(ii) shall, upon delivery by the
      Collateral Agent to such Grantor of a written notice of such Event of Default,
      cease, and all such rights shall thereupon become vested in the Collateral
      Agent, and any and all such cash dividends, interest and other cash
      distributions received by such Grantor shall be promptly delivered to the
      Collateral Agent who shall cause the Depository Bank to deposit same in a
      subaccount of the Cash Collateral Account to be administered in accordance
      with
Section 4.02(b)(iii).  With respect to
      any issuer of Pledged Equity that is a party to this Agreement, upon delivery
      by
      the Collateral Agent to such issuer of a written notice of such Event of
      Default, such issuer shall thereafter pay and deliver all dividends,
      distributions and interest described in this Section
      5.08(c)(ii) directly to the Collateral Agent, until such issuer has received
      written notice from the Collateral Agent that such Event of Default no longer
      exists.  Each Grantor that has granted a security interest in Pledged
      Equity under this Agreement in an issuer that is not a party to this Agreement,
      agrees to cause such issuer to pay and deliver all dividends, distributions
      and
      interest described in this Section 5.08(c)(ii)
      directly to the Collateral Agent.  Any such dividends, interest and
      distributions received by a Grantor contrary to the provisions of this Section 5.08(c)(ii) shall be received in trust for the
      benefit of the Collateral Agent, shall be segregated from the other funds of
      such Grantor and shall be promptly paid over to the Collateral Agent who shall
      cause the Depository Bank to deposit same in a subaccount of the Cash Collateral
      Account to be administered as above provided in this Section 5.08(c)(ii); and

     

    (iii)  all
      rights of each
      Grantor to receive the payments on Payment Collateral that it would otherwise
      be
      authorized to receive and retain pursuant to Section
      5.08(a)(iii) shall, upon delivery by the Collateral Agent to the Grantors
      and the Pipeline Company Borrowers of a written notice of such Event of Default,
      cease and thereafter all such payments shall be made by the Grantor or the
      Pipeline Company Borrower, as applicable, that is the account debtor or Person
      obligated to make payment on such Payment Collateral, directly to the Collateral
      Agent, who shall cause the Depository Bank to deposit same in a subaccount
      of
      the Cash Collateral Account to be administered in accordance with Section 4.02(b)(iii).  Any such payments
      received by a Grantor contrary to the provisions of this Section 5.08(c)(iii) shall be received in trust for the
      benefit of the Collateral Agent, shall be segregated from the other funds of
      such Grantor and shall be promptly paid over by such Grantor to the Collateral
      Agent who shall cause the Depository Bank to deposit same in a subaccount of
      the
      Cash Collateral Account to be administered in accordance with this Section 5.08(c)(iii).

     

    Section
      5.09.  The
      Collateral Agent Appointed Attorney-in-Fact.  Each Grantor hereby
      irrevocably appoints the Collateral Agent such Grantor’s attorney-in-fact, with
      full authority in the place and stead of such Grantor and in the name of such
      Grantor or otherwise, from time to time, in the Collateral Agent’s discretion,
      to take any action and to execute any instrument that the Collateral Agent
      may
      deem necessary or advisable to accomplish the purposes of this Agreement and
      any
      other Security Document with respect to the Collateral and the Collateral
      Agent’s rights and remedies with respect thereto, including:

     

    (a)  to
      ask for, demand,
      collect, sue for, recover, compromise, receive and give acquittance and receipts
      for moneys due and to become due under or in respect of any of the
      Collateral;

     

    (b)  to
      receive, indorse
      and collect any drafts or other instruments, documents and chattel paper, in
      connection with clause (a) above; and

     

    (c)  to
      file any claims
      or take any action or institute any proceedings that the Collateral Agent may
      deem necessary or desirable for the collection of any of the Collateral or
      otherwise to enforce the rights of the Collateral Agent and any other Secured
      Party with respect to any of the Collateral;

     

    provided
      that the Collateral Agent shall not exercise the power and authority granted
      to
      it pursuant to this Section 5.09 except during such
      period as an Event of Default has occurred and is continuing.

     

    Section
      5.10 .  Netting

      intangibles, instruments or chattel paper owed by it to another Credit Related
      Party by the amount of any accounts, payment intangibles, instruments or chattel

      and
      Enforcement

     

    Section
      6.01.  Remedies
      and Enforcement. (a) At such time as any Event of Default has
      occurred and is continuing, the Collateral Agent shall have the right to take
      such actions as are necessary or appropriate to enforce, implement and
      administer the provisions hereof or of any other Security Document that are
      applicable to any period during which an Event of Default has occurred and
      is
      continuing, and without limiting the foregoing, the Collateral Agent shall
      have
      and may exercise, enforce, implement and administer all rights, privileges,
      powers, benefits and remedies granted to or arising in favor of the Collateral
      Agent under such provisions with respect to any such Event of Default, including
      in each case referenced above the provisions of Section
      4.02(b)(iii), 4.03(f), 4.05(a), 4.06,
5.03(a),
5.08,
      and 5.09, with respect to any Net Cash Proceeds

      non-application of funds in Pledged Accounts, deposits or transfers of funds
      into or from Pledged Accounts or subaccounts thereof, delivery of funds from
      Pledged Accounts to the Collateral Agent, the right to direct investments,
      voting rights with respect to Security Collateral and powers of
      attorney.

     

    (b)  At
      such time as an
      Event of Default has occurred and is continuing, the Collateral Agent shall
      have
      and in its discretion may exercise any or all of the following rights and
      remedies:

     

    (i)  Enforcement
      Actions.  The Collateral Agent may take any Enforcement Action or
      Enforcement Actions (at such times, places and by such methods, as the
      Collateral Agent shall determine, including any actions incidental to carrying
      out any such Enforcement Action) in order to enforce the Security Documents
      and
      to realize upon the Collateral or, in the case of any Insolvency Proceeding
      against the Company or any of its Subsidiaries, seeking to enforce the claims
      and/or Transaction Liens, including claims under the Security
      Documents.

     

    (ii)  Sale;
      Incidents
      of Sale.  The Grantors agree that, to the extent notice of sale
      shall be required by Applicable Law with respect to the Disposition of any
      Collateral, at least ten days’ notice to the Company of the time and place of
      any public Disposition or the time after which any private Disposition is to
      be
      made shall constitute reasonable notification.  The Collateral Agent
      shall not be obligated to make any Disposition of Collateral regardless of
      notice of Disposition having been given.  The Collateral Agent may
      adjourn any public or private Disposition from time to time by announcement
      at
      the time and place fixed therefor, and such Disposition may, without further
      notice, be made at the time and place to which it was so
      adjourned.  With respect to any Disposition of any of the Collateral
      made or caused to be made by the Collateral Agent, whether made under the power
      of Disposition hereby given or pursuant to judicial proceedings, to the extent
      permitted by Applicable Law:

     

    (A)  Any
      Secured Party,
      the Company, and any of the Company’s Affiliates (including any Grantor) may bid
      for, and purchase, the Collateral offered for sale, and, upon compliance with
      the terms of sale and Applicable Law, may hold and Dispose of such property;
      and

     

    (B)  Pursuant
      to the
      power of attorney granted under Section 5.09(a), the
      Collateral Agent may, but shall not be obligated to, make all necessary deeds,
      bills of sale and instruments of assignment and transfer covering the Collateral
      Disposed of, and for that purpose the Collateral Agent may execute all necessary
      deeds, bills of sale and instruments of assignment and transfer, and may
      substitute one or more Persons with like power.

     

    (iii)  Collateral
      Agent May File Proofs of Claim.  In case of the pendency of any
      Insolvency Proceeding relative to the Company or any of its Subsidiaries or
      the
      Collateral, the Collateral Agent (irrespective of whether any of the outstanding
      Secured Obligations shall then be due and payable) shall be entitled and
      empowered (but not obligated), by intervention in such proceeding or otherwise,
      (A) to file and prove a claim for the whole amount of the Secured Obligations
      owing and unpaid in order to protect the rights of the Secured Parties under
      the
      Security Documents and with respect to the Collateral, and to file such other
      papers or documents as may be necessary or advisable in order to have the claims
      of the Collateral Agent (including any claim for the reasonable compensation,
      disbursements and advances of the Collateral Agent in its individual or trust
      capacity and its agents and counsel) and of any other Secured Parties in respect
      of the Security Documents and the Collateral allowed in such judicial proceeding
      and (B) to collect and receive any moneys or other property payable or
      deliverable on any such claims and to distribute the same; and any custodian,
      receiver, assignee, trustee, liquidator, sequestrator or other similar official
      in any such judicial proceeding is hereby authorized by each Secured Party
      to
      make payments with respect to such claims to the Collateral Agent.

     

    (iv)  Collateral
      Agent May Enforce Claims.  All rights of action and claims under
      this Agreement and the other Security Documents may be prosecuted and enforced
      by the Collateral Agent; provided that the Collateral Agent is also
      hereby appointed as agent for the other Secured Parties for the purposes of
      protecting their interests in and to any portion of the Collateral and under
      the
      Security Documents, and the Collateral Agent shall take such action solely
      as
      agent for the Secured Parties.

     

    Section
      6.02.  Application
      of Proceeds. If an Event of Default shall have occurred and
      be continuing and the Collateral Agent applies (i) any cash held in the Pledged
      Accounts or (ii) the proceeds of any Disposition of all or any part of the
      Collateral, such cash and/or proceeds shall be applied to the Secured
      Obligations in the following order of priorities:

     

                     first,to
      pay the expenses of such
      Disposition, including reasonable compensation to agents of and counsel for
      the
      Collateral Agent, and all expenses, liabilities and advances incurred or made
      by
      the Collateral Agent in connection with the Security Documents, and any other
      amounts then due and payable to the Collateral Agent in its capacity as such
      pursuant to Section 9.01 hereof or Section 10.03 of
      the Credit Agreement;

     

    second,                    to
      pay the unpaid principal of all Borrowings and all unreimbursed LC Disbursements
      and to Cash Collateralize all outstanding Letters of Credit, all ratably until
      the principal of all Borrowings and all unreimbursed LC Disbursements shall
      have
      been paid in full and all Letters of Credit shall have been Cash
      Collateralized;

     

                     third,to
      pay all other amounts owed under the
      Credit Agreement and the other Loan Documents ratably, until all such other
      amounts shall have been paid in full;

     

    fourth,                    to
      pay all other Secured Obligations ratably, until payment in full of all such
      other Secured Obligations shall have been made; and

     

    finally,                    to
      pay to the relevant Grantor, or as a court of competent jurisdiction may direct,
      any surplus then remaining from the proceeds of the Collateral owned by
      it;

     

    provided
      that Collateral owned by a Subsidiary Grantor and any proceeds thereof shall
      be
      applied pursuant to the foregoing clauses first, second,
third and fourth only to the extent permitted by the
      limitation in Section 2.01(b) of the Subsidiary Guarantee
      Agreement.  The Collateral Agent may make such distributions hereunder
      in cash or in kind or, on a ratable basis, in any combination
      thereof.

     

    Section
      6.03.  Other
      Remedies of Secured Parties.  Except as the same relates to the
      Collateral or as otherwise expressly prohibited by this Agreement or any other
      Security Document, each Secured Party may exercise any right or power, enforce
      any remedy, give any direction, consent or waiver or make any determination,
      under or in respect of any provision of any Financing Document to which it
      is a
      party.  Notwithstanding the foregoing, no Secured Party other than the
      Collateral Agent shall have the right to take any Enforcement Action with
      respect to the Collateral or the Subsidiary Guarantee Agreement or seek to
      exercise and enforce the Transaction Liens, and all such Enforcement Actions
      shall be effected solely through the Collateral Agent.  No reference
      in this Agreement to the Collateral Agent’s making a demand for payment under
      the Subsidiary Guarantee Agreement shall be construed to mean that such a demand
      is required in order to cause any obligation under the Subsidiary Guarantee
      Agreement to become due and payable, it being understood that obligations under
      the Subsidiary Guarantee Agreement shall become due and payable at such times
      as
      they become due and payable under the terms of the Subsidiary Guarantee
      Agreement.

    Section
      9.01.  Indemnity
      and Expenses.  (a) Each Credit Party agrees to
      indemnify (without duplication), defend and save and hold harmless each of
      the
      Collateral Agent, the Depository Bank and the Secured Parties and each of their
      Affiliates and their respective officers, directors, employees, agents and
      advisors (each, an “Indemnified Party”) from and against, and
      shall pay, any and all claims, damages, losses, liabilities and expenses
      (including reasonable fees and expenses of counsel) that may be incurred by
      or
      asserted or awarded against any Indemnified Party, in each case arising out
      of
      or in connection with (i) this Agreement or the other Security Documents, or
      (ii) as a result of the execution or delivery of this Agreement or the other
      Security Documents or the performance by the Credit Parties hereto and thereto
      of their respective obligations hereunder and thereunder, except in each case
      of
      clause (i) and (ii), as
      to any particular Indemnified Party, to the extent such claim, damage, loss,
      liability or expense is found in a final, nonappealable judgment by a court
      of
      competent jurisdiction to have resulted from, or to be attributable to, the
      gross negligence or willful misconduct of such Indemnified Party or its
      employees or agents.  The indemnification provisions of this Section 9.01(a) are not intended to constitute a
      guaranty of payment of any principal, interest, facility or commitment fees,
      rental or other lease payments, or analogous amounts, under any Secured
      Obligations; provided that nothing in this Section 9.01(a) shall limit the liability of any Credit
      Party for the payment of any Secured Obligation, to the extent such liability
      arises under any other Financing Document, including any liability arising
      under
      this Agreement.

     

    (b)  Each
      Credit Party
      will pay to the Collateral Agent the amount of any and all reasonable
      out-of-pocket expenses, including the reasonable fees and expenses of its
      counsel and of any experts and agents, that the Collateral Agent may incur
      in
      connection with (i) the administration of this Agreement and the other Security
      Documents, (ii) the custody, preservation, or the sale of, collection from
      or
      other realization upon, any of the Collateral of such Credit Party, (iii) the
      exercise or enforcement of any of the rights of the Collateral Agent or any
      other Secured Party hereunder, or (iv) the failure by such Credit Party to
      perform or observe any of the provisions hereof required to be performed or
      observed by it.

     

    (c)  The
      indemnities
      provided by the Credit Parties pursuant to this Agreement shall survive the
      expiration, cancellation, termination or modification of this Agreement or
      the
      other Security Documents, the resignation or removal of the Collateral Agent,
      Depository Bank or Secured Parties and the provision of any subsequent or
      additional indemnity by any Person.

     

    (d)  All
      amounts due
      under this Section 9.01 shall be payable not later
      than 30 days after the delivery of written demand to the Company
      therefor.

     

    Section
      9.02.  Amendments;
      Waivers, Etc. No amendment, modification or waiver of any provision of this
      Agreement or any other Security Document, and no consent with respect to any
      departure by the Collateral Agent, any other Secured Party or any Credit Party
      herefrom or therefrom, shall be effective unless the same shall be in writing
      and signed by the Credit Parties and the Collateral Agent in accordance with
      the
      Credit Agreement.  Any such waiver or consent shall be effective only
      in the specific instance and for the specific purpose for which
      given.

     

    Section
      9.03.  Security
      Interest Absolute and Waivers.  (a)  The
      obligations of each Credit Party under or in respect of this Agreement or any
      other Security Document to which such Credit Party is a party are independent
      of
      the Secured Obligations or any other obligations of any other Credit Party
      under
      or in respect of the Financing Documents, and a separate action or actions
      may
      be brought and prosecuted by the Collateral Agent against each Credit Party
      to
      enforce this Agreement or any other Security Document to which such Credit
      Party
      is a party, irrespective of whether any action is brought against the Company
      or
      any other Credit Party or whether the Company or any other Credit Party is
      joined in any such action or actions.  All rights of the Collateral
      Agent and the other Secured Parties and the Liens granted by the Grantors
      hereunder, and all obligations of each Credit Party hereunder, shall be
      unaffected by, and each Credit Party hereby irrevocably waives (to the maximum
      extent permitted by applicable law) any defenses to its obligations under the
      Security Documents that it may now have or may hereafter acquire, which defenses
      in any way relate to, any or all of the following:

      lack of
      validity or enforceability of any Financing Document or any other agreement
      or
      instrument relating thereto;

     

    (ii)  any
      change in the
      time, manner or place of payment of, or in any other term of, all or any of the
      Secured Obligations or any other obligations of any Credit Party under or in
      respect of the Financing Documents or any other amendment or waiver of or any
      consent to any departure from any Financing Document, including any increase
      in
      the Secured Obligations resulting from the extension of additional credit to
      any
      Credit Party or any of its Subsidiaries or otherwise;

     

    (iii)  any
      Condemnation,
      exchange, release or non-perfection of any Collateral or any other collateral,
      or any release, amendment or waiver of, or consent to, or departure from any
      Guaranty of all or any of the Secured Obligations;

     

    (iv)  any
      manner of
      application of any Collateral or any other collateral, or proceeds thereof,
      to
      all or any of the Secured Obligations, or any manner of sale or other
      disposition of any Collateral or any other collateral for all or any of the
      Secured Obligations or any other obligations of any Credit Party under or in
      respect of the Financing Documents or any other assets of any Credit Party
      or
      any of its Subsidiaries;

     

    (v)  any
      change,
      restructuring or termination of the corporate structure or existence of any
      Credit Party or any of its Subsidiaries;

     

    (vi)  any
      failure of any
      Secured Party to disclose to any Credit Party any information relating to the
      business, condition (financial or otherwise), operations, performance, assets,
      nature of assets, liabilities or prospects of any other Credit Party now or
      hereafter known to such Secured Party (each Credit Party waiving any duty on
      the
      part of the Secured Parties to disclose such information);

     

    (vii)  the
      failure of any
      other Person to execute or deliver this Agreement or any other Security
      Document, guaranty or agreement or the release or reduction of liability of
      any
      Credit Party or other grantor or surety with respect to the Secured Obligations;
      or

     

    (viii)  any
      other
      circumstance (including any statute of limitations) or any existence of or
      reliance on any representation by any Secured Party that might otherwise
      constitute a defense available to, or a discharge of, such Credit Party or
      any
      other Credit Party or third party grantor of a secured interest, but
      specifically excluding any defense or discharge arising as a result of
      performance or indefeasible payment.

     

    (b)  This
      Agreement
      shall continue to be effective or be reinstated, as the case may be, if at
      any
      time any payment of any of the Secured Obligations is rescinded or must
      otherwise be returned by any Secured Party or by any other Person upon the
      insolvency, bankruptcy or reorganization of any Credit Party or otherwise,
      all
      as though such payment had not been made.

     

    (c)  Each
      Credit Party
      hereby unconditionally and irrevocably waives promptness, diligence, notice
      of
      acceptance, presentment, demand for performance, notice of nonperformance,
      default, notice of intent to accelerate, acceleration, protest or dishonor
      and
      any other notice with respect to any of the Secured Obligations and this
      Agreement or any other Security Document to which such Credit Party is a party
      and any requirement that any Secured Party protect, secure, perfect or insure
      any Lien or any property subject thereto or exhaust any right or take any action
      against any Credit Party or any other Person or any Collateral.

     

    (d)  Each
      Credit Party
      hereby unconditionally and irrevocably waives any right to revoke this Agreement
      or any other Security Document to which such Credit Party is a party and
      acknowledges that this Agreement or any other Security Document to which such
      Credit Party is a party is continuing in nature and applies to all Secured
      Obligations, whether existing now or in the future.

     

    (e)  Each
      Credit Party
      hereby unconditionally and irrevocably waives (i) any defense arising by reason
      of any claim or defense based upon an election of remedies by the Collateral
      Agent that in any manner impairs, reduces, releases or otherwise adversely
      affects the subrogation, reimbursement, exoneration, contribution or
      indemnification rights of such Credit Party or other rights of such Credit
      Party
      to proceed against any other Credit Party, any other guarantor or any other
      Person or any Collateral and (ii) any defense based on any right of set-off
      or
      counterclaim against or in respect of the obligations of such Credit Party
      hereunder.

     

    (f)  Each
      Credit Party
      and each of the Secured Parties confirms that it is the intention of all such
      Persons that this Agreement, the other Security Documents and the obligations
      of
      each Credit Party hereunder or thereunder do not constitute a fraudulent
      transfer or fraudulent conveyance for purposes of the Bankruptcy Code, the
      Uniform Fraudulent Conveyance Act, the Uniform  Fraudulent Transfer
      Act or any similar foreign, federal or state law to the extent applicable to
      this Agreement, any other Security Document and the obligations of each Credit
      Party hereunder or thereunder or in connection with any Insolvency Proceeding
      in
      respect of any Credit Party.  To effectuate the foregoing intention,
      the Collateral Agent, the other Secured Parties and the Subsidiary Grantors
      hereby irrevocably agree that the obligations of each Subsidiary Grantor under
      this Agreement and the other Security Documents at any time shall not exceed
      the
      maximum amount as will result in the obligations of such Subsidiary Grantor
      under this Agreement and the other Security Documents not constituting a
      fraudulent transfer or fraudulent conveyance (after giving effect to Section
      2.02 of the Subsidiary Guarantee Agreement).

     

    (g)  Each
      Credit Party
      acknowledges that it will receive substantial direct and indirect benefits
      from
      the financing arrangements contemplated by the Security Documents and that
      the
      waivers set forth in this Section 9.03 are knowingly
      made in contemplation of such benefits.

      successors, transferees and assigns.  Without limiting the generality
      of the foregoing clause (c), each Secured Party may
      assign, sell or otherwise transfer all or any portion of its rights and
      obligations in respect of any Secured Obligations held by it to any other
      Person, and such other Person shall thereupon become vested with all the
      benefits in respect thereof granted to such Secured Party herein or otherwise,
      in each case subject to the Financing Documents.

     

    Section
      9.06.  [Reserved].

     

    Section
      9.07.  Execution
      in Counterparts.  This Agreement may be executed in any number of
      counterparts, each of which when so executed shall be deemed to be an original
      and all of which taken together shall constitute one and the same
      agreement.  Delivery of an executed counterpart of a signature page to
      this Agreement by telecopier shall be effective as delivery of an original
      executed counterpart of this Agreement.

     

    Section
      9.08.  Severability.  If
      any provision of this Agreement shall be invalid, illegal or unenforceable,
      then
      to the extent permitted by law, the validity, legality and enforceability of
      the
      remaining provisions shall not in any way be affected or impaired
      thereby.

     

    Section
      9.09.  Integration.  This
      Agreement and the other Financing Documents represent the agreement of the
      parties hereto with respect to the subject matter hereof, and there are no
      promises, undertakings, representations or warranties by any party relative
      to
      subject matter hereof not expressly set forth or referred to herein or in the
      other Financing Documents.

     

    Section
      9.10.  No
      Partnership.  Nothing contained in this Agreement and no action
      by any Secured Party is intended to constitute or shall be deemed to constitute
      the Secured Parties (or any of them) a partnership, association, joint venture
      or other entity.

     

    Section
      9.11.  No
      Reliance.  No Secured Party has relied on any representation or
      warranty of any other Secured Party with respect to this Agreement and the
      transactions contemplated hereunder unless such representation or warranty
      has
      been set forth expressly in this Agreement.

     

    Section
      9.12.  Release.  On
      the date hereof, without further action by any party to this Agreement or the
      Existing Security Agreement, each of the Released Parties shall cease to be
      a
      Subsidiary Grantor under the Existing Security Agreement, and shall not be
      deemed a Subsidiary Grantor under this Agreement.

     

    Section
      9.13.  No
      Impairment.  Nothing in this Agreement is intended or shall be
      construed to impair, diminish or otherwise adversely affect any other rights
      the
      Secured Parties may have or may obtain against the Company, any other Credit
      Party or any other Person.

     

    Section
      9.14.  Equitable
      Remedies.  Each party to this Agreement acknowledges that the
      breach by it of any of the provisions of this Agreement is likely to cause
      irreparable damage to the other party.  Therefore, the relief to which
      any party shall be entitled in the event of any such breach or threatened breach
      shall include, but not be limited to, a mandatory injunction for specific
      performance, injunctive or other judicial relief to prevent a violation of
      any
      of the provisions of this Agreement, damages and any other relief to which
      it
      may be entitled at law or in equity.

     

    Section
      9.15.  Remedies.  (a)
      Other than as stated expressly herein, no remedy herein conferred upon the
      Collateral Agent or any other Secured Party is intended to be exclusive of
      any
      other remedy and each and every such remedy shall be cumulative and shall be
      in
      addition to every other remedy given under this Agreement or the other Financing
      Documents, or now or hereafter existing at law or in equity or by statute or
      otherwise.

     

    (b)  As
      between the
      Credit Parties and each Secured Party, it is agreed that the amounts payable
      by
      the Company at any time in respect of the Secured Obligations shall be a
      separate and independent debt and each Secured Party shall be entitled, subject
      to Section 6.03, to protect and enforce its rights
      arising out of the Financing Documents to which it is a party and its right,
      pursuant to the terms of any Financing Document to which it is a party, to
      cancel or suspend its commitments thereunder and to accelerate the maturity
      of
      any of the Secured Obligations, in each case in accordance with the applicable
      Financing Documents, and, except as aforesaid, it shall not be necessary for
      any
      other Secured Party to consent to, or be joined as an additional party in,
      any
      proceedings for such purposes.

     

    (c)  In
      case the
      Collateral Agent shall have proceeded to enforce any right, remedy or power
      under this Agreement or any other Security Document and the proceeding for
      the
      enforcement thereof shall have been discontinued or abandoned for any reason
      or
      shall have been determined adversely to the Collateral Agent, then and in every
      such case the Credit Parties and the Secured Parties shall, subject to any
      effect of or determination in such proceeding, severally and respectively be
      restored to their former positions and rights under this Agreement or any other
      Security Document and thereafter all rights, remedies and powers of the Secured
      Parties shall continue as though no such proceeding had been taken.

     

    Section
      9.16.  Limitations.  (a)  The
      obligations, liabilities or responsibilities of any party hereunder shall be
      limited to those obligations, liabilities or responsibilities expressly set
      forth and attributed to such party pursuant to this Agreement or otherwise
      applicable under Applicable Law.

     

    (b)  In
      no event shall
      any Secured Party be liable for, and each of the Credit Parties hereby agrees
      not to assert any claim against any Secured Party, on any theory of liability,
      for consequential, incidental, indirect, punitive or special damages arising
      out
      of or otherwise relating to this Agreement, the other Financing Documents,
      any
      of the transactions contemplated herein or therein, or the actual or proposed
      use of the proceeds of any Loan, Letter of Credit or Secured Hedging
      Agreement.

     

    Section
      9.17.  Survival.  Notwithstanding
      anything in this Agreement to the contrary, Sections 9.01, 9.17, 9.19,
9.20
      and 9.21 shall survive any termination of this
      Agreement.  In addition, each representation and warranty made or
      deemed to be made hereunder shall survive the Effective Date.

     

    Section
      9.18.  [Reserved].

     

    Section
      9.19.  Jurisdiction,
      Etc.(a)  Each of the parties hereby irrevocably and
      unconditionally submits, for itself and its property, to the nonexclusive
      jurisdiction of the Supreme Court of the State of New York, sitting in New
      York
      County, and of the United States District Court for the Southern District of
      New
      York, and any appellate court from any thereof, in any action or proceeding
      by
      the Collateral Agent or any Secured Party arising out of or relating to this
      Agreement or any of the other Security Documents to which it is a party or
      under
      which it is a beneficiary, or for recognition or enforcement of any judgment
      obtained in any such action or proceeding, and each of the parties hereto hereby
      irrevocably and unconditionally agrees that all claims in respect of any such
      action or proceeding may be heard and determined in such New York State court
      or, to the fullest extent permitted by law, in such Federal
      court.  Each of the parties hereto agrees that a final judgment in any
      such action or proceeding shall be conclusive and may be enforced in other
      jurisdictions by suit on the judgment or in any other manner provided by
      law.  Nothing in this Agreement shall affect any right that any
      Secured Party may otherwise have to bring any action or proceeding relating
      to
      this Agreement, the Security Documents or any of the other Financing Documents
      in the courts of any jurisdiction.

     

    (b)  Each
      of the parties
      irrevocably and unconditionally waives, to the fullest extent it may legally
      and
      effectively do so, any objection that it may now or hereafter have to the laying
      of venue of any suit, action or proceeding arising out of or relating to this
      Agreement or any of the other Security Documents to which it is a party in
      any
      court referred to in paragraph (a) of this
      Section.  Each of the parties hereto hereby irrevocably waives, to the
      fullest extent permitted by law, the defense of an inconvenient forum to the
      maintenance of such action or proceeding in any such court.

     

    (c)  Each
      party to this
      Agreement irrevocably consents to service of process in any action or proceeding
      referred to in this Section 9.19 by the mailing
      thereof by certified mail, return receipt requested, addressed as provided
      in Section 9.04(a), with a copy thereof to the “General
      Counsel” of such Person at such same address.  Nothing in this
      Agreement will affect the right of any party to this Agreement to serve process
      in any other manner permitted by law.

     

    Section
      9.20.  GOVERNING
      LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
      ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     

    Section
      9.21.  Waiver
      of Jury Trial.  EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST
      EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY
      IN
      ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
      AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,
      TORT OR ANY OTHER THEORY).  EACH PARTY HERETO (a) CERTIFIES THAT NO
      REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
      OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION,
      SEEK
      TO ENFORCE THE FOREGOING WAIVER, AND (b) ACKNOWLEDGES THAT IT AND THE OTHER
      PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
      THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     

    

    
      
              

                      

        

        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    IN
      WITNESS WHEREOF, each party hereto has caused this Agreement to be duly executed

    The
      Credits

     

    Section
      2.01.  Commitments.
      Subject to the terms and conditions set forth herein, each Lender agrees
      to
      make Loans to any Borrower from time to time during the Availability Period
      in
      an aggregate principal amount that will not result in any Lender’s Outstandings
      exceeding such Lender’s Commitment.  Within the foregoing limits and
      subject to the terms and conditions set forth herein, each Borrower may borrow,
      prepay and reborrow Loans.

     

    Section
      2.02.  Loans
      and Borrowings.  (a) Each Loan shall be made as part of a
      Borrowing consisting of Loans of the same Type made by the Lenders ratably
      in
      accordance with their respective Commitments, as the applicable Borrower may
      request (subject to Section 2.12) in accordance
      herewith.  The failure of any Lender to make any Loan required to be
      made by it shall not relieve any other Lender of its obligations hereunder;
      provided that the Commitments of the Lenders are several and no Lender
      shall be responsible for any other Lender’s failure to make Loans as
      required.

     

    (b)  Subject
      to Section 2.12, each Borrowing shall be comprised
      entirely of ABR Loans or Eurodollar Loans as the Company, on its own behalf
      or
      on behalf of the applicable Pipeline Company Borrower, may request in accordance
      herewith.  Each Lender at its option may make or hold any Eurodollar
      Loan by causing any domestic or foreign branch or Affiliate of such Lender
      to
      make or hold such Loan; provided that any exercise of such option shall
      not affect the obligation of a Borrower to repay such Loan in accordance with
      the terms of this Agreement.

     

    (c)  At
      the commencement
      of each Interest Period for any Eurodollar Borrowing, such Borrowing shall
      be in
      an aggregate amount that is an integral multiple of $1,000,000 and not less
      than
      $20,000,000.  At the time that each ABR Borrowing is made, such
      Borrowing shall be in an aggregate amount that is an integral multiple of
      $1,000,000 and not less than $5,000,000; provided that an ABR Borrowing
      may be in an aggregate amount that is equal to the entire unused balance of
      the
      total Commitments or that is required to finance the reimbursement of an LC
      Disbursement as contemplated by Section
      2.04(e).  Borrowings of more than one Type may be outstanding at
      the same time; provided that there shall not at any time be more than a
      total of sixteen Eurodollar Borrowings outstanding.  Within the limits
      of each Lender’s Commitment, any Borrower may make more than one Borrowing on
      any Business Day.

     

    (d)  Notwithstanding
      any
      other provision of this Agreement, a Borrower shall not be entitled to request,
      or to elect to convert a Borrowing to or continue a Borrowing as, a Eurodollar
      Borrowing if the Interest Period requested with respect thereto would end after
      the Maturity Date.

     

    Section
      2.03.  Requests
      for Borrowings.  To request a Borrowing, the Company, on its own
      behalf or on behalf of the applicable Pipeline Company Borrower, shall notify
      the Administrative Agent of such request by telephone (a) in the case of a
      Eurodollar Borrowing, not later than 12:00 noon, New York City time, three
      Business Days before the date of the proposed Borrowing, or (b) in the case
      of
      an ABR Borrowing, not later than 10:00 a.m., New York City time, on the date
      of
      the proposed Borrowing.  Each such telephonic Borrowing Request shall
      be irrevocable and shall be confirmed promptly by hand delivery or telecopy
      to
      the Administrative Agent of a written Borrowing Request in substantially the
      form of Exhibit B and signed by the Company.  Each such
      telephonic and written Borrowing Request shall specify the following information
      in compliance with Section 2.02:

     

    (i)  the
      Borrower;

     

    (ii)  the
      aggregate
      amount of such Borrowing;

     

    (iii)  the
      date of such
      Borrowing, which shall be a Business Day;

     

    (iv)  whether
      such
      Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

     

    (v)  in
      the case of any
      Eurodollar Borrowing, the initial Interest Period to be applicable thereto,
      which shall be a period contemplated by the definition of the term “Interest
      Period”; and

     

    (vi)  the
      location and
      number of the Borrower’s account to which funds are to be
      disbursed.

     

    (1)  If
      no election as
      to the Type of Borrowing is specified, then the requested Borrowing shall be
      an
      ABR Borrowing.  If no Interest Period is specified with respect to any
      requested Eurodollar Borrowing, then the applicable Borrower shall be deemed
      to
      have selected an Interest Period of one month’s duration.  Promptly
      following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise
      each Lender of the details thereof and of the amount of such Lender’s Loan to be
      made as part of the requested Borrowing.

     

    Section
      2.04.  Letters
      of Credit.

     

    (a)  General.  (i)
      Subject to the terms and conditions set forth herein, upon request by the
      Company, on its own behalf or on behalf of the applicable Pipeline Company
      Borrower, each Issuing Bank agrees to issue Letters of Credit in any stated
      face
      amount specified by the Company in the applicable request with any Borrower
      as
      the reimbursement obligor in respect of drawings thereunder and for the account
      of the Borrowers, or any one or more of them, or any direct or indirect
      Subsidiary or Affiliate thereof, each Letter of Credit in a form reasonably
      acceptable to the Administrative Agent and the applicable Issuing Bank, at
      any
      time and from time to time during the  Availability
      Period.  In the event of any inconsistency between the terms and
      conditions of this Agreement and the terms and conditions of any form of letter
      of credit application, reimbursement agreement or other agreement submitted
      by a
      Borrower to, or entered into by a Borrower with, an Issuing Bank relating to
      any
      Letter of Credit issued thereby, the terms and conditions of this Agreement
      shall control.

     

    (ii)  Existing
      Letters of Credit.  On the Effective Date, without further action
      by any party hereto, each Issuing Bank that has issued an Existing Letter of
      Credit shall be deemed to have granted to each Lender, and each Lender shall
      be
      deemed to have acquired from such Issuing Bank, a participation in each such
      Existing Letter of Credit equal to such Lender’s Percentage of (A) the aggregate
      amount available to be drawn under such Existing Letter of Credit and (B) the
      aggregate amount of any outstanding reimbursement obligations in respect
      thereof.  With respect to each Existing Letter of Credit (i) any
      participation therein granted pursuant to the terms of the Existing Facility
      shall be automatically canceled on the Effective Date and (ii) if the relevant
      Issuing Bank has heretofore granted a participation therein to any bank or
      financial institution otherwise than pursuant to the terms of the Existing
      Facility, such Issuing Bank shall procure the termination of such participation
      on or prior to the Effective Date.  On and after the Effective Date,
      each such Existing Letter of Credit shall be a Letter of Credit issued
      hereunder.

     

    (b)  Notice
      of
      Issuance, Amendment, Renewal, Extension; Certain Conditions.  To
      request the issuance of a Letter of Credit (or the amendment, renewal or
      extension of an outstanding Letter of Credit), the Company, on its own behalf,
      or on behalf of the applicable Pipeline Company Borrower as obligor, shall
      hand
      deliver or telecopy (or transmit by electronic communication, if arrangements
      for doing so have been approved by the applicable Issuing Bank) to the Issuing
      Bank requested to issue such Letter of Credit and the Administrative Agent
      (reasonably in advance of the requested date of issuance, amendment, renewal
      or
      extension) a notice (requesting the issuance of a Letter of Credit, or
      identifying the Letter of Credit to be amended, renewed or extended, and
      specifying the date of issuance, amendment, renewal or extension (which shall
      be
      a Business Day), the date on which such Letter of Credit is to expire (which
      shall comply with paragraph (c) of this Section 2.04), the amount of
      such Letter of Credit, the
      name and address of the beneficiary thereof and such other information
      (including the applicable Borrower as obligor for reimbursement obligations
      thereunder and the account party therefor if different) as shall be necessary
      to
      prepare, amend, renew or extend such Letter of Credit.  If such notice
      is received by the applicable Issuing Bank (i) prior to 12:00 noon, New York
      City time, on any Business Day, the applicable Issuing Bank shall use its best
      efforts to issue the requested Letter of Credit on such date or (ii) after
      12:00
      noon, New York City time, on any Business Day, the applicable Issuing Bank
      shall
      issue the requested Letter of Credit by the end of the following Business Day,
      in each case provided that all necessary information is in order.  If
      requested by the applicable Issuing Bank in connection with any request for
      a
      Letter of Credit, the applicable obligor Borrower in respect thereof also shall
      submit a letter of credit application on such Issuing Bank’s standard
      form.  A Letter of Credit shall be issued, amended, renewed or
      extended only if (and upon issuance, amendment, renewal or extension of each
      Letter of Credit the Company shall be deemed to represent and warrant that),
      after giving effect to such issuance, amendment, renewal or extension (i) the
      total LC Exposure with respect to all Letters of Credit issued by each Issuing
      Bank shall not exceed such Issuing Bank’s LC Commitment and (ii) the total
      Outstandings shall not exceed the total Commitments.  Each Issuing
      Bank shall have sole discretion as to any amendment, renewal or extension of
      the
      Letters of Credit issued by it, subject to the other terms and provisions of
      this Agreement.

     

    (c)  Expiration
      Date.  Each Letter of Credit shall expire at or prior to the
      close of business on the earlier of (i) the date three years after the date
      of
      the issuance of such Letter of Credit (or, in the case of any renewal or
      extension thereof, three years after such renewal or extension) and (ii) the
      date that is five Business Days prior to the Maturity Date; provided
      that (x) any Letter of Credit may provide for the extension or renewal thereof
      and may be renewed or extended upon the request of the Company, on its own
      behalf or on behalf of a Pipeline Company Borrower, in accordance with the
      terms
      thereof for additional periods of a duration requested by the Company, on its
      own behalf or on behalf of a Pipeline Company Borrower (which shall in no event
      extend beyond the date referred to in clause (ii)
      above) and (y) with the consent of the relevant Issuing Bank and the
      Administrative Agent, Letters of Credit with a term longer than three years
      shall be permitted (which shall in no event extend beyond the date referred
      to
      in clause (ii) above).

     

    (d)  Participations.  By
      the issuance of a Letter of Credit (or an amendment to a Letter of Credit
      increasing the amount thereof) and without any further action on the part of
      the
      applicable Issuing Bank or the applicable Lenders, such Issuing Bank hereby
      grants to each Lender having a Commitment, and each Lender hereby acquires
      from
      such Issuing Bank, a participation in such Letter of Credit equal to such
      Lender’s Percentage of the aggregate amount available to be drawn under such
      Letter of Credit.  In consideration and in furtherance of the
      foregoing, each such Lender hereby absolutely and unconditionally agrees to
      pay
      to the Administrative Agent, for the account of the applicable Issuing Bank,
      such Lender’s Percentage of each LC Disbursement made by such Issuing Bank and
      not reimbursed by the applicable obligor Borrower or any Guarantor on the date
      due as provided in paragraph (e) of this Section 2.04, or of any reimbursement
      payment required
      to be refunded to any Borrower for any reason.  Each Lender
      acknowledges and agrees that its obligation to acquire participations pursuant
      to this paragraph
      in respect of Letters of Credit is absolute and unconditional and shall not
      be
      affected by any circumstance whatsoever, including any amendment, renewal or
      extension of any Letter of Credit or the occurrence and continuance of a Default
      or reduction or termination of the Commitments, and that each such payment
      shall
      be made without any offset, abatement, withholding or reduction
      whatsoever.

     

    (e)  Reimbursement.  If
      an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit
      issued by it, the applicable obligor Borrower shall reimburse such LC
      Disbursement by paying to the Administrative Agent an amount equal to such
      LC
      Disbursement not later than 12:00 noon, New York City time, on the date that
      such LC Disbursement is made, if such Borrower shall have received notice of
      such LC Disbursement prior to 10:00 a.m., New York City time, on such date,
      or,
      if such notice has not been received by such Borrower prior to such time on
      such
      date, then not later than 12:00 noon, New York City time, on (i) the Business
      Day that such Borrower receives such notice, if such notice is received prior
      to
      10:00 a.m., New York City time, on the day of receipt, or (ii) the Business
      Day
      immediately following the day that such Borrower receives such notice, if such
      notice is not received prior to such time on the day of receipt;
provided that, to the extent financed with proceeds of an ABR Borrowing
      as contemplated by the following sentence, such Borrower’s obligation to make
      such payment shall be discharged and replaced by the resulting ABR
      Borrowing.  Unless the Company, on its own behalf or on behalf of the
      applicable Pipeline Company Borrower, shall have notified the Administrative
      Agent of such Borrower’s intention to reimburse the Administrative Agent
      directly for such LC Disbursement, the Administrative Agent shall notify each
      Lender of the applicable LC Disbursement, the payment then due from such
      Borrower in respect thereof and such Lender’s Percentage
      thereof.  Promptly following receipt of such notice, each applicable
      Lender shall make an ABR Loan in the amount of its Percentage of the payment
      then due from the applicable Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender
      (and Section 2.05 shall apply, mutatis
      mutandis, to the payment obligations of the applicable Lenders), and the
      Administrative Agent shall promptly pay to the applicable Issuing Bank the
      amounts so received by it from such Lenders.  Promptly following
      receipt by the Administrative Agent of any payment from a Borrower pursuant
      to
      this paragraph, the Administrative Agent shall distribute such payment to the
      applicable Issuing Bank or, to the extent that Lenders have made payments
      pursuant to this paragraph
      to reimburse such Issuing Bank, then to the Lenders and such Issuing Bank as
      their interests may appear.

     

    (f)  Obligations
      Absolute.  Each Borrower’s obligation to reimburse LC
      Disbursements as provided in paragraph (e) of this
Section 2.04 shall be absolute,
      unconditional and
      irrevocable, and shall be performed strictly in accordance with the terms of
      this Agreement under any and all circumstances whatsoever and irrespective
      of
      (i) any lack of validity or enforceability of any Letter of Credit or this
      Agreement, or any term or provision therein, (ii) any draft or other document
      presented under a Letter of Credit proving to be forged, fraudulent or invalid
      in any respect or any statement therein being untrue or inaccurate in any
      respect, (iii) payment by the applicable Issuing Bank under a Letter of Credit
      against presentation of a draft or other document that does not comply with
      the
      terms of such Letter of Credit, or (iv) any other event or circumstance
      whatsoever, whether or not similar to any of the foregoing, that might, but
      for
      the provisions of this Section 2.04, constitute a
      legal or equitable discharge of or defense to, or provide a right of setoff
      against, a Borrower’s obligations hereunder.  Neither the
      Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related
      Parties, shall have any liability or responsibility by reason of or in
      connection with the issuance or transfer of any Letter of Credit or any payment
      or failure to make any payment thereunder (irrespective of any of the
      circumstances referred to in the preceding sentence), or any error, omission,
      interruption, loss or delay in transmission or delivery of any draft, notice
      or
      other communication under or relating to any Letter of Credit (including any
      document required to make a drawing thereunder), any error in interpretation
      of
      technical terms or any consequence arising from causes beyond the control
      of  such Issuing Bank; provided that the foregoing shall not
      be construed to excuse such Issuing Bank from liability to a Borrower to the
      extent of any direct damages (as opposed to consequential damages, claims in
      respect of which are hereby waived by the applicable Borrower to the extent
      permitted by applicable law) suffered by a Borrower that are caused by such
      Issuing Bank’s failure to comply with the requirements of the ISP or the Uniform
      Customs, as applicable, when determining whether drafts and other documents
      presented under a Letter of Credit comply with the terms thereof.  In
      furtherance of the foregoing, the parties agree that, with respect to documents
      presented which appear on their face to be in compliance with the terms of
      a
      Letter of Credit, the Issuing Bank that issued such Letter of Credit may, to
      the
      extent it is permitted to do so under the ISP or Uniform Customs, as applicable,
      and otherwise in its sole discretion, either accept and make payment upon such
      documents without responsibility for further investigation, regardless of any
      notice or information to the contrary, or refuse to accept and make payment
      upon
      such documents if such documents are not in strict compliance with the terms
      of
      such Letter of Credit (unless the applicable obligor Borrower shall consent
      to
      payment thereon notwithstanding such lack of strict compliance).

     

    (g)  Disbursement
      Procedures.  Each Issuing Bank shall, promptly following its
      receipt thereof, examine all documents purporting to represent a demand for
      payment under a Letter of Credit issued by it.  Such Issuing Bank
      shall promptly notify the Administrative Agent and the Borrower by telephone
      (confirmed by telecopy) of the date and the amount of such demand for payment
      and whether such Issuing Bank has made or will make an LC Disbursement
      thereunder; provided that any failure to give or delay in giving such
      notice shall not relieve such Borrower of its obligation to reimburse such
      Issuing Bank and the Lenders with respect to any such LC
      Disbursement.

     

    (h)  Interim
      Interest.  If any Issuing Bank shall make any LC Disbursement,
      then, unless the applicable obligor Borrower, or a Guarantor on its behalf,
      shall reimburse such LC Disbursement in full on the date such LC Disbursement
      is
      made (including reimbursement by way of ABR Loans made as contemplated by paragraph
      (e) of this Section 2.04), the unpaid amount thereof
      shall bear interest, for each day from and including the date such LC
      Disbursement is made to but excluding the date that such Borrower reimburses
      such LC Disbursement, at the rate per annum then applicable to ABR Loans;
provided that, if such applicable obligor Borrower, or a Guarantor on
      its behalf, fails to reimburse such LC Disbursement when due pursuant to
      paragraph (e) of this Section 2.04, then Section
      2.11(c) shall apply.  Interest accrued pursuant to this paragraph
      shall be for the account of the applicable Issuing Bank, except that interest
      accrued on and after the date of payment by any Lender pursuant to paragraph
(e) of this Section 2.04 to
      reimburse such Issuing Bank shall be for the account of such Lender to the
      extent of such payment.

     

    (i)  Replacement
      of
      an Issuing Bank.  Any Issuing Bank may be replaced at any time by
      written agreement among the Company, the Administrative Agent, the replaced
      Issuing Bank and the successor Issuing Bank.  The Administrative Agent
      shall notify the Lenders of any such replacement of an Issuing
      Bank.  At the time any such replacement shall become effective, the
      applicable obligor Borrower shall pay all unpaid fees accrued for the account
      of
      the replaced Issuing Bank pursuant to Section
      2.10(b).  From and after the effective date of any such
      replacement, (i) the successor Issuing Bank shall have all the rights and
      obligations of the replaced Issuing Bank under this Agreement with respect
      to
      Letters of Credit issued by it thereafter and (ii) references herein to the
      term
“Issuing Bank” shall be deemed, when applicable, to refer to
      such successor or, when applicable, to any previous Issuing Bank, or to such
      successor and all previous Issuing Banks, as the context shall
      require.  After the replacement of an Issuing Bank hereunder, the
      replaced Issuing Bank shall remain a party hereto and shall continue to have
      all
      the rights and obligations of an Issuing Bank under this Agreement with respect
      to Letters of Credit issued by it prior to such replacement, but shall not
      be
      required to issue additional Letters of Credit.

     

    (j)  Cash
      Collateralization.  Notwithstanding any provisions of the
      Security Agreement relating to the Cash Collateralization of LC Exposure, if
      any
      Event of Default shall occur and be continuing, on the Business Day that any
      Borrower receives notice from the Administrative Agent or the Majority Lenders
      demanding the Cash Collateralization of the LC Exposure pursuant to this
      paragraph, such Borrower shall Cash Collateralize the LC Exposure;
provided that the obligation to deposit such cash collateral shall
      become effective immediately, and such deposit shall become immediately due
      and
      payable, without demand or other notice of any kind, upon the occurrence of
      any
      Event of Default with respect to such Borrower described in paragraph (f) of Article
      7.  If any Borrower is required to provide an amount of Cash
      Collateral hereunder as a result of the occurrence of an Event of Default,
      such
      amount (to the extent not applied as aforesaid) shall be returned to such
      Borrower within three Business Days after all Events of Default have been cured
      or waived.

     

    Section
      2.05.  Funding
      Of Borrowings.  (a) Each Lender shall make each Loan to be made
      by it hereunder on the proposed date of the related Borrowing by wire transfer
      of immediately available funds by 12:00 noon, New York City time, to the account
      of the Administrative Agent most recently designated by it for such purpose
      by
      notice to the Lenders.  The Administrative Agent will make such Loans
      available to the applicable Borrower by promptly crediting the Loan amounts
      so
      received, in like funds, to such account as designated by such Borrower in
      the
      applicable Borrowing Request; provided that ABR Loans made to finance
      the reimbursement of an LC Disbursement as provided in Section 2.04(e) shall be remitted by the Administrative
      Agent to the applicable Issuing Bank.

     

    (b)  Unless
      the
      Administrative Agent shall have received notice from a Lender prior to the
      proposed date (or, in the case of a requested ABR Borrowing for which notice
      has
      been provided by the Company on the same date of the proposed disbursement,
      the
      proposed time) of any Borrowing that such Lender will not make available to
      the
      Administrative Agent such Lender’s share of such Borrowing, the Administrative
      Agent may assume that such Lender has made such share available on such date
      in
      accordance with paragraph (a) of this Section 2.05 and may, in reliance
      upon such assumption,
      make available to the applicable Borrower a corresponding amount.  In
      such event, if a Lender has not in fact made its share of a Borrowing available
      to the Administrative Agent, then the applicable Lender and Borrower severally
      agree to pay to the Administrative Agent forthwith on demand such corresponding
      amount with interest thereon, for each day from and including the date such
      amount is made available to such Borrower to but excluding the date of payment
      to the Administrative Agent, at (i) in the case of such Lender, the greater
      of
      the Federal Funds Effective Rate and a rate determined by the Administrative
      Agent in accordance with banking industry rules on interbank compensation,
      or
      (ii) in the case of the Borrower, the interest rate applicable to ABR
      Loans.  If such Lender pays such amount to the Administrative Agent,
      then such amount shall constitute such Lender’s Loan included in such
      Borrowing.

     

    Section
      2.06.  Interest
      Elections.  (a)  Each Borrowing initially shall be of
      the Type specified in the applicable Borrowing Request and, in the case of
      a
      Eurodollar Borrowing, shall have an initial Interest Period as specified in
      such
      Borrowing Request.  The Company, on its own behalf or on behalf of a
      Pipeline Company Borrower, may thereafter elect at any time and from time to
      time on any Business Day to convert such Borrowing to a different Type or to
      continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect
      Interest Periods therefor, all as provided in this Section 2.06.  The Company, on its own behalf
      or on behalf of a Pipeline Company Borrower, may elect different options with
      respect to different portions of the affected Borrowing, in which case each
      such
      portion shall be allocated ratably among the Lenders holding the Loans
      comprising such Borrowing, and the Loans comprising each such portion shall
      be
      considered a separate Borrowing.

     

    (b)  To
      make an election
      pursuant to this Section 2.06, a Borrower shall
      notify the Administrative Agent of such election by telephone not later than
      12:00 noon, New York City time, three Business Days before the proposed
      effective date of such election.  Each such telephonic Interest
      Election Request shall be irrevocable and shall be confirmed promptly by hand
      delivery or telecopy to the Administrative Agent of a written Interest Election
      Request in a form approved by the Administrative Agent and signed by such
      Borrower.

     

    (c)  Each
      telephonic and
      written Interest Election Request shall specify the following information in
      compliance with Section 2.02:

     

    (i)  the
      Borrowing to
      which such Interest Election Request applies and, if different options are
      being
      elected with respect to different portions thereof, the portions thereof to
      be
      allocated to each resulting Borrowing (in which case the information to be
      specified pursuant to clauses (iii) and (iv) below shall be specified
      for each resulting
      Borrowing);

     

    (ii)  the
      effective date
      of the election made pursuant to such Interest Election Request, which shall
      be
      a Business Day;

     

    (iii)  whether
      the
      resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;
      and

     

    (iv)  if
      the resulting
      Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable
      thereto after giving effect to such election, which shall be a period
      contemplated by the definition of the term “Interest
      Period”.

     

    (2)  If
      any such
      Interest Election Request requests a Eurodollar Borrowing but does not specify
      an Interest Period, then the Borrower shall be deemed to have selected an
      Interest Period of one month’s duration.

     

    (d)  Promptly
      following
      receipt of an Interest Election Request, the Administrative Agent shall advise
      each Lender of the details thereof and of such Lender’s portion of each
      resulting Borrowing.

     

    (e)  If
      a Borrower fails
      to deliver a timely Interest Election Request with respect to a Eurodollar
      Borrowing prior to the end of the Interest Period applicable thereto, then,
      unless such Borrowing is repaid as provided herein, at the end of such Interest
      Period such Borrowing shall be converted to an ABR
      Borrowing.  Notwithstanding any contrary provision hereof, if an Event
      of Default has occurred and is continuing and the Administrative Agent, at
      the
      request of the Majority Lenders, so notifies any Borrower, then, so long as
      an
      Event of Default is continuing (i) no outstanding Borrowing may be converted
      to
      or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar
      Borrowing shall be converted to an ABR Borrowing at the end of the Interest
      Period applicable thereto.

     

    Section
      2.07.  Optional
      and Mandatory Termination and Reduction of Commitments.  (a)
      Unless previously terminated, the Commitments shall terminate on the Maturity
      Date.

     

    (b)  The
      Company may at
      any time terminate, or from time to time reduce, the unused portions of the
      Commitments; provided that (i) each partial reduction of the
      Commitments shall be in an amount that is an integral multiple of $1,000,000
      and
      not less than $10,000,000, and (ii) the Company shall not terminate or reduce
      the Commitments if, after giving effect to any concurrent prepayment of Loans
      in
      accordance with Section 2.09, the Outstandings would
      exceed the aggregate amount of the Commitments.

     

    (c)  The
      Company shall
      notify the Administrative Agent of any election to terminate or reduce the
      Commitments under paragraph (b) of this Section 2.07, or any required
      reduction of the
      Commitments under paragraph (d) of this Section 2.07, at least three
      Business Days prior to the
      effective date of such termination or reduction, specifying such election and
      the effective date thereof.  Promptly following receipt of any notice,
      the Administrative Agent shall advise the Lenders of the contents
      thereof.  Each notice delivered by the Company pursuant to this Section 2.07 shall be irrevocable; provided
      that a notice of termination of the Commitments delivered by the Company may
      state that such notice is conditioned upon the effectiveness of other credit
      facilities, in which case such notice may be revoked by the Company (by notice
      to the Administrative Agent on or prior to the specified effective date) if
      such
      condition is not satisfied.

     

    (d)  Within
      five days
      after the occurrence of a Mandatory Asset Reduction Event, the Commitments
      shall
      be ratably reduced (but not below zero) by an aggregate amount equal to the
      related Mandatory Asset Reduction Amount.

     

    (e)  Any
      termination or
      reduction of the Commitments hereunder, whether optional or mandatory, shall
      be
      permanent.  Each reduction of the Commitments shall be made ratably
      among the Lenders in accordance with their respective Commitments.

     

    Section
      2.08.  Repayment
      of Loans; Evidence of Debt.  (a)  Each Borrower hereby
      unconditionally promises to pay on the Maturity Date to the Administrative
      Agent
      for the account of each Lender the then unpaid principal amount of each Loan
      made to such Borrower.

     

    (b)  Each
      Lender shall
      maintain in accordance with its usual practice an account or accounts evidencing
      the indebtedness of each Borrower to such Lender resulting from each Loan made
      by such Lender to such Borrower, including the amounts of principal and interest
      payable and paid to such Lender from time to time hereunder.

     

    (c)  The
      Administrative
      Agent shall maintain accounts in which it shall record (i) the amount of each
      Loan made hereunder, the Type thereof, the Interest Period applicable thereto
      and the Borrower to whom such Loan is made, (ii) the amount of any principal
      or
      interest due and payable or to become due and payable to each Lender hereunder
      on account of each Loan from the relevant Borrower to whom such Loan was made
      and (iii) the amount of any sum received by the Administrative Agent hereunder
      for the account of the Lenders and each Lender’s share thereof.

     

    (d)  The
      entries made in
      the accounts maintained pursuant to paragraph (b) or
(c) of this Section
      2.08
      shall, to the extent permitted by applicable law, be prima facie
      evidence of the existence and amounts of the obligations of each Borrower
      recorded therein absent manifest error; provided that the failure of
      any Lender or the Administrative Agent to maintain any such account or any
      error
      therein shall not in any manner affect the obligation of each Borrower to repay
      the Loans made to such Borrower in accordance with the terms of this
      Agreement.

     

    (e)  Any
      Lender may
      request that Loans made by it be evidenced by a Note.  In such event,
      the applicable Borrower shall prepare, execute and deliver to such Lender a
      Note
      or Notes payable to the order of such Lender (or, if requested by such Lender,
      to such Lender and its registered assigns).  Thereafter, the Loans
      evidenced by such Note and interest thereon shall at all times (including after
      assignment pursuant to Section 10.04) be represented
      by one or more Notes in such form payable to the order of the payee named
      therein (or, if such Note is a registered note, to such payee and its registered
      assigns).

     

    Section
      2.09.  Optional
      and Mandatory Prepayment of Loans.  (a)  Any Borrower
      shall have the right at any time and from time to time to prepay any Borrowing
      in whole or in part (without premium or penalty but subject to Section 2.14), subject to prior notice in accordance
      with paragraph (b) of this Section 2.09.  All or any portion
      of any Loan
      prepaid may be borrowed and reborrowed in accordance with the terms and
      provisions of this Agreement.

     

    (b)  A
      Borrower shall
      notify the Administrative Agent by telephone (confirmed by telecopy) of any
      optional prepayment hereunder (i) in the case of prepayment of a Eurodollar
      Borrowing, not later than 12:00 noon, New York City time, two Business Days
      before the date of prepayment, or (ii) in the case of prepayment of an ABR
      Borrowing, not later than 12:00 noon, New York City time, on the date of
      prepayment.  Each such notice shall be irrevocable and shall specify
      the prepayment date and the principal amount of each Borrowing or portion
      thereof to be prepaid; provided that, if a notice of prepayment is
      given in connection with a conditional notice of termination of the Commitments
      as contemplated by Section 2.07(c), then such notice
      of prepayment may be revoked if such notice of termination is revoked in
      accordance with Section 2.07(c).  Promptly
      following receipt of any such notice relating to a Borrowing, the Administrative
      Agent shall advise the Lenders of the contents thereof.  Each optional
      partial prepayment of any Borrowing shall be in a minimum amount of $5,000,000
      or a larger integral multiple of $1,000,000.  Each optional prepayment
      of a Borrowing shall be applied ratably to the Loans included in the prepaid
      Borrowing.  Each prepayment shall be accompanied by accrued and unpaid
      interest to the extent required by Section
      2.11.

     

    (c)  If
      on any date
      (including any date on which a mandatory reduction of Commitments occurs
      pursuant to Section 2.07(d)) the aggregate
      Outstandings exceed the then aggregate Commitments, then, without notice or
      demand, the Company shall promptly cause to be prepaid the principal amount
      of
      the Loans and any unreimbursed LC Disbursements in an amount equal to such
      excess and, if all Loans and unreimbursed LC Disbursements shall have been
      prepaid, promptly cause to be Cash Collateralized outstanding Letters of Credit
      by an amount equal to any remaining excess.

     

    Section
      2.10.  Fees.  (a)
      The Company agrees to pay to the Administrative Agent for the account of each
      Lender a commitment fee, which shall accrue at the Applicable Rate on the daily
      amount of the excess of the Commitment of such Lender over such Lender’s
      Outstandings during the period from and including the date hereof to but
      excluding the date on which such Commitment terminates.

     

    (b)  The
      Company agrees
      to pay (i) to the Administrative Agent for the account of each Lender a
      participation fee with respect to its participations in Letters of Credit,
      which
      shall accrue at the same Applicable Rate used to determine the interest rate
      applicable to Eurodollar Loans on the average daily amount of such Lender’s LC
      Exposure (excluding any portion thereof attributable to unreimbursed LC
      Disbursements) during the period from and including the Effective Date to but
      excluding the later of the date on which such Lender’s Commitment terminates and
      the date on which such Lender ceases to have any LC Exposure, (ii) to each
      Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum
      on the average daily amount of the LC Exposure (excluding any portion thereof
      attributable to unreimbursed LC Disbursements) with respect to each Letter
      of
      Credit issued by such Issuing Bank during the period from and including the
      Effective Date to but excluding the later of the date of termination of the
      Commitments and the date on which there ceases to be any LC Exposure with
      respect to Letters of Credit issued by such Issuing Bank and (iii) to each
      Issuing Bank, such Issuing Bank’s standard fees with respect to the issuance,
      amendment, renewal or extension of any Letter of Credit issued by it or
      processing of drawings thereunder.

     

    (c)  Fees
      accrued
      pursuant to paragraphs
      (a), (b)(i) and (b)(ii) above, through and including the last day of March,
      June, September and December of each year shall be payable on the third Business
      Day following each such last day, commencing on the first such date to occur
      after the Effective Date; provided that all such fees for the account
      of the Lenders shall be payable on the date on which the Commitments terminate
      and any such fees accruing after the date on which the Commitments terminate
      shall be payable on demand.  All such fees shall be computed on the
      basis of a year of 365 days (or 366 days in a leap year) and shall be payable
      for the actual number of days elapsed (including the first day but excluding
      the
      last day).  Any other fees payable to any Issuing Bank pursuant to
      this Section shall be payable within 10 days after demand.

     

    (d)  The
      Company agrees
      to pay (i) to the Administrative Agent, the Collateral Agent and the Lead
      Arrangers, for their own accounts, fees payable in the amounts and at the times
      separately agreed to pursuant to the Fee Letter and (ii) on or prior to the
      Effective Date, to the Administrative Agent for the account of each Lender
      an
      upfront fee in an amount separately agreed with the Lenders.

     

    (e)  All
      fees payable
      hereunder shall be paid on the dates due, in immediately available funds, to
      the
      Administrative Agent (or to each Issuing Bank, in the case of fees payable
      to
      it) for distribution (if applicable) to the Lenders as specified
      above.  Fees paid shall not be refundable under any
      circumstances.

     

    Section
      2.11.  Interest.  (a)  The
      Loans comprising each ABR Borrowing shall bear interest at the Alternate Base
      Rate plus the Applicable Rate.

     

    (b)  The
      Loans
      comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO
      Rate for the Interest Period in effect for such Borrowing plus the Applicable
      Rate.

     

    (c)  Notwithstanding
      the
      foregoing, if any principal of or interest on any Loan or any fee or other
      amount payable by any Borrower hereunder is not paid when due, whether at stated
      maturity, upon acceleration or otherwise, such overdue amount shall bear
      interest, after as well as before judgment, at a rate per annum equal to (i)
      in
      the case of overdue principal of any Loan, 2% plus the  rate otherwise
      applicable to such Loan as provided in the preceding paragraphs
      of this Section 2.11 or (ii) in the case of any
      other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph
      (a) of this Section
      2.11.

     

    (d)  Accrued
      interest on
      each Loan shall be payable in arrears on each Interest Payment Date for such
      Loan and upon termination of the Commitments; provided that (i)
      interest accrued pursuant to paragraph (c) of this
Section 2.11 shall be payable
      on demand, (ii) in the
      event of any repayment or prepayment of any Loan, accrued interest on the
      principal amount repaid or prepaid shall be payable on the date of such
      repayment or prepayment and (iii) in the event of any conversion of any
      Eurodollar Loan prior to the end of the current Interest Period therefor,
      accrued interest on such Loan shall be payable on the effective date of such
      conversion.

     

    (e)  All
      interest
      hereunder shall be computed on the basis of a year of 360 days, except that
      interest computed by reference to the Alternate Base Rate at times when the
      Alternate Base Rate is based on the Prime Rate shall be computed on the basis
      of
      a year of 365 days (or 366 days in a leap year), and in each case shall be
      payable for the actual number of days elapsed (including the first day but
      excluding the last day of the Interest Period).  The applicable
      Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by
      the
      Administrative Agent, and such determination shall be conclusive absent manifest
      error.

     

    Section
      2.12.  Alternate
      Rate of Interest.  If prior to the commencement of any Interest
      Period for a Eurodollar Borrowing:

     

    (a)  the
      Administrative
      Agent determines in good faith (which determination shall be conclusive absent
      manifest error) that, by reason of circumstances generally affecting the London
      interbank Eurodollar market, adequate and reasonable means do not exist for
      ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such
      Interest Period; or

     

    (b)  the
      Administrative
      Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or the
      LIBO
      Rate, as applicable, for such Interest Period will not adequately and fairly
      reflect the cost to such Lenders of making or maintaining their Loans included
      in such Borrowing for such Interest Period;

     

    (3)  then
      the
      Administrative Agent shall give notice thereof to the Borrowers and the Lenders
      by telephone or telecopy as promptly as practicable thereafter and, until the
      Administrative Agent notifies the Borrowers and the Lenders that the
      circumstances giving rise to such notice no longer exist, (m) any Interest
      Election Request that requests the conversion of any Borrowing to, or
      continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective,
      and (n) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing
      shall be made as an ABR Borrowing.

     

    Section
      2.13.  Increased
      Costs.

     

    (a)  If
      any Change in
      Law shall:

     

    (i)  impose,
      modify or
      deem applicable any reserve, special deposit or similar requirement against
      assets of, deposits with or for the account of, or credit extended by, any
      Lender (except any such reserve requirement reflected in the Adjusted LIBO
      Rate)
      or any Issuing Bank; or

     

    (ii)  impose
      on any
      Lender or any Issuing Bank or the London interbank market any other condition
      materially affecting this Agreement or Eurodollar Loans made by such Lender
      or
      any Letter of Credit or participation therein;

     

    (1)  in
      each case other
      than as specified in paragraph (b) below, and the
      result of any of the foregoing shall be to increase the cost to such Lender
      of
      making or maintaining any Eurodollar Loan (or of maintaining its obligation
      to
      make any such Loan) or to increase the cost to such Lender or such Issuing
      Bank
      of participating in, issuing or maintaining any Letter of Credit or to reduce
      the amount of any sum received or receivable by such Lender or such Issuing
      Bank
      hereunder (whether of principal, interest or otherwise), in each case by an
      amount that such Lender or such Issuing Bank reasonably deems to be material,
      then the applicable Borrower or Borrowers will pay to such Lender or such
      Issuing Bank, as the case may be, in accordance with paragraph (c) of this Section 2.13
      after such Borrower’s receipt of its written demand accompanied by documentation
      specifying in reasonable detail the events and circumstances and the applicable
      Change in Law in support of any such reimbursement request, such additional
      amount or amounts necessary to compensate such Lender or such Issuing Bank,
      as
      the case may be, for such additional costs incurred or reduction
      suffered.

     

    (b)  If
      any Lender or
      any Issuing Bank determines that any Change in Law regarding capital
      requirements has or would have the effect of reducing the rate of return on
      such
      Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or
      such Issuing Bank’s holding company, if any, as a consequence of this Agreement
      or the Loans made by, or participations in Letters of Credit held by, such
      Lender, or the Letters of Credit issued by such Issuing Bank, to a level below
      that which such Lender or such Issuing Bank or such Lender’s or such Issuing
      Bank’s holding company could have achieved but for such Change in Law (taking
      into consideration such Lender’s or such Issuing Bank’s policies and the
      policies of such Lender’s or such Issuing Bank’s holding company with respect to
      capital adequacy) by an amount reasonably deemed by such Lender or such Issuing
      Bank to be material, then from time to time upon submission by such Lender
      or
      such Issuing Bank to the applicable Borrower or Borrowers (with a copy to the
      Administrative Agent) of a written demand therefor accompanied by documentation
      specifying in reasonable detail the events and circumstances applicable to
      such
      reduction and the applicable Change in Law in support of such demand, and the
      amount demanded pursuant hereto, the applicable Borrower or Borrowers will,
      within 30 days after receipt of such demand, pay to such Lender or such Issuing
      Bank, as the case may be, such additional amount or amounts necessary to
      compensate such Lender or such Issuing Bank or such Lender’s or such Issuing
      Bank’s holding company for any such reduction suffered.

     

    (c)  A
      certificate of a
      Lender or such Issuing Bank setting forth the amount or amounts necessary to
      compensate such Lender or such Issuing Bank or its holding company, as the
      case
      may be, together with the relevant demand and accompanying documentation, all
      as
      specified in paragraph (a) or (b) of this Section
      2.13,
      shall be delivered to the Company and shall be conclusive absent manifest
      error.  The Company shall pay such Lender or such Issuing Bank, as the
      case may be, the amount shown as due on any such certificate within 30 days
      after receipt thereof.

     

    (d)  Failure
      or delay on
      the part of any Lender or any Issuing Bank to demand compensation pursuant
      to
      this Section 2.13 shall not constitute a waiver of
      such Lender’s or such Issuing Bank’s right to demand such compensation;
provided that a Borrower shall not be required to compensate a Lender
      or an Issuing Bank pursuant to this Section for any increased costs or
      reductions incurred more than 180 days prior to the date that such Lender or
      such Issuing Bank, as the case may be, notifies the Company of the Change in
      Law
      giving rise to such increased costs or reductions and of such Lender’s or such
      Issuing Bank’s intention to claim compensation therefor in accordance with this
      Section; providedfurther that, if the Change in Law giving
      rise to such increased costs or reductions is retroactive, then the 180-day
      period referred to above shall be extended to include the period of retroactive
      effect thereof.

     

    Section
      2.14.  Break
      Funding Payments.  In the event of (a) the payment of any
      principal of any Eurodollar Loan other than on the last day of an Interest
      Period applicable thereto (including as a result of an Event of Default or
      any
      prepayment under Section 2.09(a) or 2.09(c)), (b)
      the conversion of any Eurodollar Loan other than on the last day of the Interest
      Period applicable thereto, (c) the failure to borrow, convert, continue or
      prepay any Eurodollar Loan on the date specified in any notice delivered
      pursuant hereto (regardless of whether such notice may be revoked under Section 2.09(b) and is revoked in accordance
      therewith), or (d) the assignment of any Eurodollar Loan other than on the
      last
      day of the Interest Period applicable thereto as a result of a request by a
      Borrower pursuant to Section 2.17, then, in any such
      event, such Borrower shall compensate each Lender for the loss, cost and expense
      attributable to such event.  In the case of a Eurodollar Loan, such
      loss, cost or expense to any Lender shall be deemed to include an amount
      determined by such Lender to be the excess, if any, of (i) the amount of
      interest which would have accrued on the amount so prepaid or converted, or
      not
      so borrowed, continued, converted or prepaid, at the Adjusted LIBO Rate that
      would have been applicable to such Eurodollar Loan, for the period from the
      date
      of such event to the last day of the then current Interest Period therefor
      (or,
      in the case of a failure to borrow, convert or continue, for the Interest Period
      that would have commenced on the date of such failure for such Loan), over
      (ii)
      the amount of interest that would have accrued to such Lender on such principal
      amount for such period at the interest rate which such Lender would bid were
      it
      to bid, at the commencement of such period, for dollar deposits of a comparable
      amount and period from other banks in the interbank eurodollar
      market.  A certificate of any Lender setting forth any amount or
      amounts that such Lender is entitled to receive pursuant to this Section shall
      be delivered to the applicable Borrower and shall be conclusive absent manifest
      error.  Each affected Lender requesting payment under this Section
      shall submit written demand specifying in reasonable detail the events and
      circumstances resulting in such payment obligation, together with a certificate
      as to any amounts payable pursuant to this Section to the applicable
      Borrower.  The applicable Borrower shall pay such Lender the amount
      shown as due on any such certificate within 30 days after receipt
      thereof.

     

    Section
      2.15.  Taxes.  (a)  Any
      and all payments by or on account of any obligation of any Borrower hereunder
      shall be made free and clear of and without deduction for any Indemnified Taxes
      or Other Taxes; provided that if a Borrower shall be required to deduct
      any Indemnified Taxes or Other Taxes from such payments, then (i) the sum
      payable shall be increased as necessary so that after making all required
      deductions (including deductions applicable to additional sums payable under
      this Section) the Administrative Agent, Lender or Issuing Bank (as the case
      may
      be) receives an amount equal to the sum it would have received had no such
      deductions been made, (ii) such Borrower shall make such deductions, and (iii)
      such Borrower shall pay the full amount deducted to the relevant Governmental
      Authority in accordance with applicable law.

     

    (b)  In
      addition, each
      Borrower shall pay any Other Taxes to the relevant Governmental Authority in
      accordance with applicable law.

     

    (c)  Each
      Borrower shall
      indemnify the Administrative Agent, each Lender and each Issuing Bank, within
      10
      days after written demand therefor, for the full amount of any Indemnified
      Taxes
      or Other Taxes paid by the Administrative Agent, such Lender or such Issuing
      Bank, as the case may be, on or with respect to any payment by or on account
      of
      any obligation of any Borrower hereunder (including Indemnified Taxes or Other
      Taxes imposed or asserted on or attributable to amounts payable under this
      Section) and any penalties, interest and reasonable expenses arising therefrom
      or with respect thereto, whether or not such Indemnified Taxes or Other Taxes
      were correctly or legally imposed or asserted by the relevant Governmental
      Authority.  A certificate as to the amount of such payment or
      liability delivered to a Borrower by a Lender or an Issuing Bank, or by the
      Administrative Agent on its own behalf or on behalf of a Lender or an Issuing
      Bank, shall be conclusive absent manifest error.

     

    (d)  As
      soon as
      practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower
      to a Governmental Authority, such Borrower shall deliver to the Administrative
      Agent the original or a certified copy of a receipt issued by such Governmental
      Authority evidencing such payment, a copy of the return reporting such payment
      or other evidence of such payment reasonably satisfactory to the Administrative
      Agent.

     

    (e)  Any
      Foreign Lender
      that is entitled to an exemption from or reduction of withholding tax under
      the
      law of the United States, or of the jurisdiction in which the Borrower is
      located, or any treaty to which such jurisdiction is a party, with respect
      to
      payments under this Agreement shall deliver to the Borrowers (with a copy to
      the
      Administrative Agent), at the time or times prescribed by applicable law, such
      properly completed and executed forms or other documentation prescribed by
      applicable law or reasonably requested by a Borrower as will permit such
      payments to be made without withholding or at a reduced rate.

     

    (f)  The
      Administrative
      Agent or a Lender shall determine if, in its reasonable discretion, it has
      received a refund of any Indemnified Taxes or Other Taxes as to which it has
      been indemnified by a Borrower or with respect to which a Borrower has paid
      additional amounts pursuant to this Section
      2.15.  If it determines that it has received any such refund, it
      shall pay over such refund to such Borrower (but only to the extent of indemnity
      payments made, or additional amounts paid, by such Borrower under this Section 2.15 with respect to the Indemnified Taxes or
      Other Taxes giving rise to such refund), net of all out-of-pocket expenses
      of
      the Administrative Agent or such Lender and without interest (other than any
      interest paid by the relevant Governmental Authority with respect to such
      refund); provided that each Borrower, upon the request of the
      Administrative Agent or such Lender, agrees to repay the amount paid over to
      such Borrower (plus any penalties, interest or other charges imposed by the
      relevant Governmental Authority) to the Administrative Agent or such Lender
      in
      the event the Administrative Agent or such Lender is required to repay such
      refund to such Governmental Authority.  This Section shall not be
      construed to require the Administrative Agent or any Lender to make available
      its tax returns (or any other information relating to its taxes which it deems
      confidential) to any Borrower or any other Person.

     

    Section
      2.16.  Payments
      Generally; Pro Rata Treatment; Sharing of Set-Offs.  (a) Each
      Borrower shall make each payment required to be made by it hereunder and, unless
      stated otherwise therein, under any of the other Loan Documents (whether of
      principal, interest, fees or reimbursement of LC Disbursements, or of amounts
      payable under Section 2.13, 2.14 or 2.15,
      or otherwise)
      prior to 12:00 noon, New York City time, on the date when due, in immediately
      available funds, without set-off or counterclaim.  Any amounts
      received after such time on any date may, in the discretion of the
      Administrative Agent, be deemed to have been received on the next succeeding
      Business Day for purposes of calculating interest thereon.  All such
      payments shall be made to the Administrative Agent at its offices at 270 Park
      Avenue, New York, New York, except payments to be made directly to an Issuing
      Bank as expressly provided herein and except that payments pursuant to Sections
      2.13, 2.14, 2.15
      and 10.03 shall be
      made directly to the Persons entitled thereto.  The Administrative
      Agent shall distribute any such payments received by it for the account of
      any
      other Person to the appropriate recipient promptly following receipt
      thereof.  If any payment hereunder shall be due on a day that is not a
      Business Day, the date for payment shall be extended to the next succeeding
      Business Day, and, in the case of any payment accruing interest, interest
      thereon shall be payable for the period of such extension.  All
      payments hereunder shall be made in dollars.

     

    (b)  Except
      as otherwise
      provided in Section 2.09(c), if at any time
      insufficient funds are received by and available to the Administrative Agent
      to
      pay fully all amounts of principal, unreimbursed LC Disbursements, interest
      and
      fees then due hereunder, such funds shall be applied (i) first, towards payment
      of interest and fees then due hereunder, ratably among the parties entitled
      thereto in accordance with the amounts of interest and fees then due to such
      parties, and (ii) second, towards payment of principal and unreimbursed LC
      Disbursements then due hereunder, ratably among the parties entitled thereto
      in
      accordance with the amounts of principal and unreimbursed LC Disbursements
      then
      due to such parties.

     

    (c)  If
      any Lender
      shall, by exercising any right of set-off or counterclaim or otherwise, obtain
      payment in respect of any principal of or interest on any of its Loans or
      participations in LC Disbursements resulting in such Lender receiving payment
      of
      a greater proportion of the aggregate amount of its Loans and participations
      in
      LC Disbursements and accrued interest thereon than the proportion received
      by
      any other Lender, then the Lender receiving such greater proportion shall
      purchase (for cash at face value) participations in the Loans and participations
      in LC Disbursements of other Lenders to the extent necessary so that the benefit
      of all such payments shall be shared by the Lenders ratably in accordance with
      the aggregate amount of principal of and accrued interest on their respective
      Loans and participations in LC Disbursements; provided that (i) if any
      such participations are purchased and all or any portion of the payment giving
      rise thereto is recovered, such participations shall be rescinded and the
      purchase price restored to the extent of such recovery, without interest, and
      (ii) the provisions of this paragraph
      shall not be construed to apply to any payment made by a Borrower pursuant
      to
      and in accordance with the express terms of this Agreement or any payment
      obtained by a Lender as consideration for the assignment of or sale of a
      participation in any of its Loans or participations in LC Disbursements to
      any
      assignee or participant, other than to a Borrower or any Subsidiary or Affiliate
      thereof (as to which the provisions of this paragraph
      shall apply).  Each Borrower consents to the foregoing and agrees, to
      the extent it may effectively do so under applicable law, that any Lender
      acquiring a participation pursuant to the foregoing arrangements may exercise
      against the Borrower rights of set-off and counterclaim with respect to such
      participation as fully as if such Lender were a direct creditor of the Borrower
      in the amount of such participation.

     

    (d)  Unless
      the
      Administrative Agent shall have received notice from a Borrower prior to the
      date on which any payment is due to the Administrative Agent for the account
      of
      the Lenders or any Issuing Bank hereunder that such Borrower will not make
      such
      payment, the Administrative Agent may assume that such Borrower has made such
      payment on such date in accordance herewith and may, in reliance upon such
      assumption, distribute to the Lenders or the applicable Issuing Bank, as the
      case may be, the amount due.  In such event, if such Borrower has not
      in fact made such payment, then each of the Lenders or any applicable Issuing
      Bank, as the case may be, severally agrees to repay to the Administrative Agent
      forthwith on demand the amount so distributed to such Lender or such Issuing
      Bank, with interest thereon, for each day from and including the date such
      amount is distributed to it to but excluding the date of payment to or recovery
      by the Administrative Agent, at the greater of the Federal Funds Effective
      Rate
      and a rate determined by the Administrative Agent in accordance with banking
      industry rules on interbank compensation.

     

    (e)  If
      any Lender shall
      fail to make any payment required to be made by it pursuant to Section 2.04(d) or 2.04(e), 2.05(b),
      or 2.16(d), then
      the Administrative Agent may, in its discretion (notwithstanding any contrary
      provision hereof), apply any amounts thereafter received by the Administrative
      Agent for the account of such Lender to satisfy such Lender’s obligations under
      such Sections until all such unsatisfied obligations are fully
      paid.

     

    Section
      2.17.  Mitigation
      Obligations; Replacement of Lenders.  (a) If any Lender requests
      compensation under Section 2.13, or if any Borrower
      is required to pay any additional amount to any Lender or any Governmental
      Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable
      efforts to designate a different lending office for funding or booking its
      Loans
      hereunder or to assign its rights and obligations hereunder to another of its
      offices, branches or affiliates, if, in the judgment of such Lender, such
      designation or assignment (i) would eliminate or reduce amounts payable pursuant
      to Section 2.13 or 2.15,
      as the case may be, in the future and (ii) would not subject such Lender to
      any
      unreimbursed cost or expense and would not otherwise be disadvantageous to
      such
      Lender.  Each Borrower hereby agrees to pay all reasonable costs and
      expenses incurred by any Lender in connection with any such designation or
      assignment.

     

    (b)  If
      (w) any Lender
      requests compensation under Section 2.13, or (x) if
      any Borrower is required to pay any additional amount to any Lender or any
      Governmental Authority for the account of any Lender pursuant to Section 2.15, or (y) if any Lender defaults in its
      obligation to fund Loans hereunder or (z) any Lender refuses to grant its
      approval with respect to any matter requiring the approval of all Lenders and
      such matter shall have been approved by the Majority Lenders, then the Company
      may, at its sole expense and effort, upon notice to such Lender and the
      Administrative Agent, require such Lender to assign and delegate, without
      recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and
      obligations under this Agreement to an assignee that shall assume such
      obligations (which assignee may be another Lender, if a Lender accepts such
      assignment); provided that (i) the Company shall have received the
      prior written consent of the Administrative Agent, which consent shall not
      unreasonably be withheld, (ii) such Lender shall have received payment of an
      amount equal to the outstanding principal of its Loans, participations in LC
      Disbursements, accrued interest thereon, accrued fees and all other amounts
      payable to it hereunder, from the assignee (to the extent of such outstanding
      principal, participations in LC Disbursements and accrued interest and fees)
      or
      the Borrowers (in the case of all other amounts) and (iii) in the case of any
      such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant
      to Section 2.15, such assignment will result in a
      reduction in such compensation or payments.  A Lender shall not be
      required to make any such assignment and delegation if, prior thereto, as a
      result of a waiver by such Lender or otherwise, the circumstances entitling
      the
      Company to require such assignment and delegation cease to apply.

      satisfaction (or waiver in accordance with Section
      10.02) of the conditions set forth in this Section

      (and, in the event such conditions are not so satisfied or waived, the

    Section
      3.02.  Each
      Credit Event.  The obligation of each Lender to make a Loan
      (excluding any continuation or conversion of a Loan and any Loan financing
      the
      repayment of an LC Disbursement but including the Loans to be made on the
      Effective Date) on the occasion of any Borrowing, and the obligation of any
      Issuing Bank to issue a requested Letter of Credit (including the Letters of
      Credit to be deemed issued hereunder on the Effective Date but excluding the
      extension or renewal of Letters of Credit) for the account of any Borrower
      (or
      amend or increase the stated amount of any issued Letter of Credit), is subject
      to the satisfaction of the following conditions:

     

    (a)  The
      representations
      and warranties of each Borrower and each other Credit Party set forth in this
      Agreement and the other Loan Documents shall be true and correct in all material
      respects on and as of the date of such Borrowing, or the date of issuance (or
      amendment or increase in the stated amount) of such Letter of Credit, as
      applicable, unless stated to be made on or as of, or to relate to, a specific
      date or period other than the date of such Borrowing or issuance (or amendment
      or increase in the stated amount).

     

    (b)  At
      the time of and
      immediately after giving effect to such Borrowing (and, if any proceeds thereof
      are being applied substantially contemporaneously to satisfy any other
      obligation, to such application) or the issuance (or amendment or increase
      in
      the stated amount) of such Letter of Credit, as applicable, no Default shall
      have occurred and be continuing.

     

    (c)  In
      the case of the
      issuance of a Letter of Credit, to the extent not already in effect between
      the
      Company and the Issuing Bank issuing such Letter of Credit, the applicable
      Borrower shall have executed and delivered standard documentation for account
      parties or reimbursement obligors in connection with the issuances of letters
      of
      credit as is customary for such Issuing Bank and that is not otherwise
      inconsistent with the terms of this Agreement.

     

    (3)  Each
      Borrowing and
      each issuance of a (or amendment of or increase in the stated amount of an
      issued) Letter of Credit shall be deemed to constitute a representation and
      warranty by the applicable Borrower on the date thereof as to the matters
      specified in paragraphs (a) and (b) of this Section.

     

    Section
      3.03.  Changes
      In Lenders And Commitments.  On the Effective Date:

     

    (a)  The
      Deposit
      Commitments (as defined in the Existing Facility) shall terminate, and the
      Deposit Lenders shall cease to be Lenders party to this Agreement, provided
that the provisions of Sections 2.13, 2.14, 2.15
      and 10.03 shall continue to inure to the benefit of such
      Deposit Lenders.

     

    (b)  Each
      Person listed
      in Schedule 1 hereto shall be a Lender with a Commitment in the applicable
      amount set forth for such Lender in Schedule 1.

     

    (c)  Each
      Lender which
      is not a Revolving Lender (as defined in the Existing Facility) (a “New
      Lender”) shall make new Loans to the Borrowers in an amount such that,
      after giving effect thereto, the aggregate amount of such Loans shall bear
      the
      same relationship to the Commitment of such New Lender as the outstanding Loans
      of the other Lenders bear to their Commitments, such new Loans to be allocated
      ratably among all outstanding Borrowings and to be deemed part of such
      outstanding Borrowings.

     

    (d)  The
      Existing
      Letters of Credit shall become Letters of Credit hereunder, and the
      participations of the Lenders therein shall be redetermined on the basis of
      their respective Commitments set forth in Schedule 1, all pursuant to Section 2.04(b).

     

    (e)  Any
      Revolving
      Lender party to the Existing Facility but not listed in Schedule 1 shall cease
      to be a Lender party to this Agreement, shall cease to have any Commitment
      hereunder or any participation in outstanding Letters of Credit, and all Loans
      made by such Departing Lender, and all accrued interest, fees and other amounts
      payable under the Existing Facility for its account shall be due and payable
      on
      the Effective Date; provided that the provisions of Sections 2.13, 2.14, 2.15
      and 10.03 of this
      Agreement shall continue to inure to the benefit of such Departing
      Lender.

     

    (f)  Any
      Lender which is
      not a New Lender, but whose Percentage is greater than its Revolving Percentage
      (as defined in the Existing Facility) previously in effect shall be deemed
      a New
      Lender for purposes hereof to the extent of such increase, and any such Lender
      whose Percentage is less than its Revolving Percentage shall be deemed a
      Departing Lender for purposes hereof to the extent of such
      decrease.

     

    (g)  The
      Lenders which
      are parties to the Existing Facility, comprising the “Majority Lenders” as
      defined therein, hereby waive any requirement of notice of termination of the
      Commitments pursuant to Section 2.07(c) of the
      Existing Facility and of prepayment of Loans to the extent necessary to give
      effect to Section 3.01(d) and this Section 3.03.

      Company, and
      each Pipeline Company Borrower, in each case with respect to itself and its
      Subsidiaries, represents and warrants to the Administrative Agent, the
      Collateral Agent, each Issuing Bank and each Lender that:

     

    Section
      4.01.  Organization;
      Powers.  The Company is a Business Entity duly formed, validly
      existing and in good standing under the laws of the State of
      Delaware.  Each other Credit Related Party is duly organized or
      formed, validly existing and, if applicable, in good standing in the
      jurisdiction of its organization or formation.  Each Credit Related
      Party possesses all applicable Business Entity powers and all other
      authorizations and licenses necessary to engage in its business and operations
      as now conducted, the failure to obtain or maintain which would have a Material
      Adverse Effect.

     

    Section
      4.02.  Authorization.  The
      execution, delivery and performance by each Credit Party of the Loan Documents
      to which it is a party are within such Credit Party’s applicable Business Entity
      powers, have been duly authorized by all necessary applicable Business Entity
      action, and do not contravene (a) any Credit Related Party’s organizational
      documents, or (b) any law or any material contractual restriction binding on
      or
      affecting any Credit Related Party.

     

    Section
      4.03.  Governmental
      Approvals; No Conflicts.  No authorization or approval or other
      action by, and no notice to or filing with, any Governmental Authority is
      required for the due execution, delivery and performance by any Credit Party
      of
      any Loan Document to which it is a party, except those necessary to comply
      with
      laws, rules, regulations and orders required in the ordinary course to comply
      with ongoing obligations of such Credit Party under Sections 5.01, 5.02 and 5.07,
      as applicable.

     

    Section
      4.04.  Binding
      Obligation; Enforceability.  This Agreement constitutes, and the
      other Loan Documents when delivered hereunder shall constitute, the legal,
      valid
      and binding obligations of each Credit Party that is a party thereto,
      enforceable against such Credit Party in accordance with their respective terms,
      except as may be limited by any applicable bankruptcy, insolvency,
      reorganization, moratorium or similar laws affecting creditors’ rights generally
      or by general principles of equity.

     

    Section
      4.05.  Financial
      Condition.

     

    (a)  (a)

      cash
      flows of the Company and its consolidated Subsidiaries for the fiscal year
      then
      ended, reported on by Ernst & Young LLP, independent public accountants,
      copies of which have been furnished to the Administrative Agent and the Lenders
      prior to the date hereof, present fairly, in all material respects, the
      consolidated financial condition of the Company and its consolidated
      Subsidiaries as at such date and the consolidated results of the operations
      of
      the Company and its consolidated Subsidiaries for the period ended on such
      date,
      all in accordance with GAAP consistently applied (except as approved by the
      chief financial officer of such entity and as disclosed therein), excluding
      for
      purposes of this representation the effect of any subsequent revisions or
      restatements thereto that may be required by the SEC with respect to (i) the
      accounting treatment relating to the negative revision in the proven reserves
      of
      crude oil and natural gas of the Company effected as of or prior to
      December 31, 2003 by an amount equal to approximately 1.83 trillion cubic
      feet equivalent and (ii) the manner in which the Company reported changes to
      the
      accounting for various hedging transactions and related ceiling test impairment
      charges.

     

    (b)  The
      consolidated
      balance sheets of the Company and its consolidated Subsidiaries as of September
      30, 2007, and the related consolidated statements of income and cash flows

      the Company and its consolidated Subsidiaries for the fiscal period then ended,
      copies of which have been furnished to the Administrative Agent on or prior
      to
      the date hereof, present fairly, in all material respects, the consolidated
      financial condition of the Company and its consolidated Subsidiaries as at
      such
      date and the consolidated results of the operations of the Company and its
      consolidated Subsidiaries for the period ended on such date, all in accordance
      with GAAP consistently applied (except as approved by the chief financial
      officer of such entity and as disclosed therein), subject in the case of such
      unaudited statements to normal year-end audit adjustments and reduced footnote
      disclosure, excluding for purposes of this representation the effect of any
      subsequent revisions or restatements thereto that may be required by the SEC
      with respect to (i) the accounting treatment relating to the negative revision
      in the proven reserves of crude oil and natural gas of the Company effected
      as
      of or prior to December 31, 2003 by an amount equal to approximately 1.83
      trillion cubic feet equivalent and (ii) the manner in which the Company reported
      changes to the accounting for various hedging transactions and related ceiling
      test impairment charges.

     

    (c)  Except
      as set forth
      in Schedule 4.05 or in the annual and quarterly reports referred to in Section 4.07 (collectively, the “Disclosure
      Update”), as of the Effective Date, since December 31, 2006, there has
      been no Material Adverse Effect.

     

    Section
      4.06.  Compliance
      with Laws and Agreements.  Each of the Company and its
      Subsidiaries is in compliance with all laws, rules, regulations and orders
      of
      any Governmental Authority applicable to it or its property except where the
      failure to comply, individually or in the aggregate, would not, in the
      reasonable judgment of the Company, be expected to result in a Material Adverse
      Effect; provided that the alleged failures to comply with such laws,
      rules, regulations, and orders that are disclosed in any annual report on Form
      10-K, quarterly report on Form 10-Q or current report on Form 8-K filed by
      any
      Borrower with the SEC prior to the date hereof shall not be deemed at any time
      by the parties to the Loan Documents to be expected to have a Material Adverse
      Effect for any purposes hereof.

     

    Section
      4.07.  Litigation.  There
      is no action, suit or proceeding pending, or to the knowledge of any Borrower
      threatened, against or involving any Credit Related Party in any court, or
      before any arbitrator of any kind, or before or by any Governmental Authority,
      existing as of the Effective Date (x) that in the reasonable judgment of the
      Company (taking into account the availability of appeals) could reasonably
      be
      expected to have a Material Adverse Effect, except for the proceedings described
      in the Company’s annual report on Form 10-K for the year ended December 31, 2006
      or its quarterly report on Form 10-Q for the fiscal quarter ended September
      30,
      2007 (the “3rd
      Quarter 2007 10-Q”) as filed with the SEC (the “Disclosed
      Proceedings”) or (y) which purports to affect the legality, validity,
      binding effect or enforceability of the Loan Documents.  Since the
      date of filing of the 3rd Quarter
      2007 10-Q,
      there has been no adverse change in the status of the Disclosed Proceedings
      that, taking into account the availability of any appeals, could reasonably
      be
      expected to increase materially the likelihood of a Material Adverse Effect
      resulting therefrom.

     

    Section
      4.08.  Taxes.  Each
      Credit Related Party has duly filed all tax returns required to be filed by
      it,
      and has duly paid and discharged all taxes, assessments and governmental charges
      upon it or against its properties now due and payable, the failure to file
      or
      pay which, as applicable, would have a Material Adverse Effect, unless and
      to
      the extent only that the same are being contested in good faith and by
      appropriate proceedings by the Company or the applicable Credit Related
      Party.

     

    Section
      4.09.  Properties.
      (a) Each Credit Related Party has good title to its
      respective properties and assets, free and clear of all mortgages, liens and
      encumbrances, except for (i) Transaction Liens and (ii) other mortgages, liens
      and other encumbrances (including covenants, restrictions, rights, easements
      and
      minor irregularities in title) that do not materially interfere with the
      business or operations of such Credit Related Party as presently conducted
      or
      that are permitted by Section 6.01.

     

    (b)  As
      of the Effective
      Date, the Company is aware of no Liens permitted by Section 6.01(a) solely by reason of clause
      (d) of the definition of Collateral Permitted Liens.

     

    Section
      4.10.  ERISA.  (a)
      No Termination Event has occurred or is reasonably expected to occur with
      respect to any Plan which, with the giving of notice or lapse of time, or both,
      would constitute an Event of Default under paragraph
      (h) of Article 7.

     

    (b)  Each
      Plan has
      complied with the applicable provisions of ERISA and the Code where the failure
      to so comply would reasonably be expected to result in a Material Adverse
      Effect.

     

    (c)  The
      statement of
      assets and liabilities of each Plan and the statements of changes in fund
      balance and in financial position, or the statement of changes in net assets
      available for plan benefits, for the most recent plan year for which an
      accountant’s report with respect to such Plan has been prepared, copies of which
      report have been made available to the Administrative Agent, present fairly,
      in
      all material respects, the financial condition of such Plan as at such date
      and
      the results of operations of such Plan for the plan year ended on such
      date.

     

    (d)  Neither
      the Company
      nor any ERISA Affiliate has incurred, or is reasonably expected to incur, any
      Withdrawal Liability to any Multiemployer Plan which, when aggregated with
      all
      other amounts required to be paid to Multiemployer Plans in connection with
      Withdrawal Liability (as of the date of determination), would have a Material
      Adverse Effect.

     

    (e)  Neither
      the Company
      nor any ERISA Affiliate has received any notification that any Multiemployer
      Plan is in reorganization, insolvent or has been terminated, within the meaning
      of Title IV of ERISA, and no Multiemployer Plan is reasonably expected to be
      in
      reorganization, to be insolvent or to be terminated within the meaning of Title
      IV of ERISA the effect of which reorganization, insolvency or termination would
      be the occurrence of an Event of Default under paragraph
      (h) of Article 7.

     

    Section
      4.11.  Investment
      Company Act.  No Credit Party is  an “investment
      company” or a “company” controlled by an “investment company” within the meaning
      of the Investment Company Act of 1940, as amended.

     

    Section
      4.12.  Federal
      Reserve Regulations.  The Borrowings by any Borrower under this
      Agreement and the Notes and the application of the proceeds thereof as provided
      herein will not violate Regulation T, U or X of the Board of
      Governors.

     

    Section
      4.13.  Collateral.  The
      Security Agreement is effective to create in favor of the Collateral Agent,
      for
      the benefit of the Secured Parties, a valid Lien on, and security interest
      in,
      all right, title and interest of each Credit Party, as applicable, in the
      Collateral, as security for the Secured Obligations, prior and superior in
      right
      to any other Lien (except for Collateral Permitted Liens), except in each case
      above as may be limited by any applicable bankruptcy, insolvency,
      reorganization, moratorium or similar laws affecting creditors’ rights
      generally.  All financing statements have been filed that are
      necessary to perfect any security interest created pursuant to any Security
      Document that can be perfected by the filing of such financing statements and
      all actions necessary to provide control to the Collateral Agent, with respect
      to any Collateral for which control can be established in favor of the
      Collateral Agent have been taken, including delivery of such Collateral to
      the
      Collateral Agent to the extent such Collateral is certificated or for which
      possession can provide perfection with respect thereto.

     

    Section
      4.14.  Environmental
      Matters.  Except for the matters set forth on Schedule 4.14 and
      other matters that, in the aggregate, could not reasonably be expected to result
      in a Material Adverse Effect, no Credit Related Party (a) has failed to comply
      with any Environmental Law or to obtain, maintain or comply with any permit,
      license or other approval required under any Environmental Law, (b) is subject
      to any Environmental Liability, (c) has received notice of any claim with
      respect to any Environmental Liability or (d) knows of any basis for any
      Environmental Liability.

     

    Section
      4.15.  Disclosure.  The
      publicly available information filed by any Credit Related Party with the SEC
      when taken as a whole does not contain any material misstatement of fact or
      omit
      to state any material facts necessary to make the statements therein, in light
      of the circumstances under which they were made, not misleading.

     

    Section
      4.16.  Subsidiaries.  Schedule
      4.16 sets forth the name of, and the ownership interest of the Company in,
      each
      of its Subsidiaries as of October 12, 2007.

     

    All
      representations
      and warranties made by the Credit Parties herein, and any other Loan Document
      delivered pursuant hereto, shall survive the making of the Loans, the issuance
      of any Letter of Credit and the execution and delivery by the Credit Parties
      of
      the Loan Documents.

      Covenants

      (a)
      existence, (b) rights (organizational and statutory), and (c) material
      franchises, except as otherwise permitted by Section 6.04 or 6.05 or where the
      failure to so preserve would not have a Material Adverse Effect and except
      that
      nothing herein shall prevent any change in Business Entity form of the Company
      or any other Credit Related Party.

      neither the priority of such Liens nor the value of the Collateral is diminished
      as a result of such merger;

      indirectly, a wholly-owned Subsidiary of the Company and remains a Subsidiary
      Guarantor, (ii) if the Exempted Guarantor is not the continuing or surviving
      Business Entity, the continuing or surviving Business Entity unconditionally

      obligations of such Exempted Guarantor under the Loan Documents to which the
      applicable Exempted Guarantor is a party and (iii) the Lien under the Security
      Documents in favor of the Collateral Agent on any Collateral owned by the
      applicable Exempted Guarantor immediately prior to such merger, consolidation
      or
      liquidation remains effective and perfected immediately thereafter with no
      loss
      of relative priority to any other class of creditor from that existing
      immediately prior to such merger, consolidation or liquidation; and

     

    (c)  the
      Company may
      merge or consolidate with, or liquidate into, any Business Entity other than

      continuing or surviving Business Entity or (B) the continuing or surviving
      Business Entity is organized under the laws of the United States or a State
      thereof and unconditionally assumes by written agreement satisfactory to the
      Administrative Agent all of the performance and payment obligations of the
      Company under any Loan Documents to which it is a party, and (ii) the Lien
      under
      the Security Documents in favor of the Collateral Agent on any Collateral owned
      by the Company immediately prior to such merger, consolidation or liquidation
      remains effective and perfected immediately thereafter with no loss of relative
      priority to any other class of creditor (either contractually, by structural
      subordination or otherwise) from that existing immediately prior to such merger,
      consolidation or liquidation.

     

    Section
      6.06.  Use
      of Proceeds.  No Borrower shall
      use the proceeds of any Loan or any Letter of Credit for any purpose that would
      (a) whether directly or indirectly, entail a violation of any of the Regulations
      of the Board of Governors, including Regulations T, U and X or (b) constitute
      a
      use other than a general corporate purpose (it being understood that the
      payments to be made to Departing Lenders pursuant to Section 3.01(d)(ii) shall constitute a permitted use
      of proceeds pursuant to this Section
      6.06).

     

    Section
      6.07.  Transactions
      with Affiliates.  No Credit Related Party (other than an Exempted
      Guarantor) will sell, lease or otherwise transfer any property to, or purchase,
      lease or otherwise acquire any property from, or otherwise engage in any other
      transaction with, any Affiliate of the Company that is not a Subsidiary of
      the
      Company, whether or not in the ordinary course of business, except (a)
      transactions on terms no less favorable to such Credit Related Party as would
      be
      obtainable by such Credit Related Party at the time in a comparable arm’s-length
      transaction or series of transactions with a person other than an Affiliate
      of
      the Company, (b) any Disposition permitted under Section
      6.04 or any merger, consolidation or liquidation permitted under Section 6.05 and (c) transactions the value of which
      are de minimis in relation to the assets, liabilities or revenues of
      the Credit Related Party engaging in such transaction.

     

    Section
      6.08.  Restrictive
      Agreements. No Credit Related Party will, directly or indirectly, enter
      into or permit to exist any agreement or other arrangement that prohibits,
      restricts or imposes any condition on (a) the ability of any Credit Related
      Party (other than the Company or the Exempted Guarantor) to create or permit
      to
      exist any Lien on any of its property or (b) the ability of any Restricted
      Subsidiary or Pipeline Company Borrower to pay dividends or other distributions
      with respect to any shares of its capital stock or to make or repay loans or

      the
      Company or any Subsidiary Guarantor or to otherwise transfer assets to or invest

      the foregoing shall not apply to customary restrictions and conditions contained
      in agreements relating to the sale of a Subsidiary pending such sale,
provided that such restrictions and conditions apply only to the
      Subsidiary that is to be sold and such sale is permitted hereunder, (iv) clause
      (a) of this Section shall not apply to restrictions or conditions imposed by
      any
      agreement relating to secured Debt permitted by this Agreement if such
      restrictions or conditions apply only to the property securing such Debt, (v)
      clause
      (a) of this Section shall not apply to customary provisions in leases and other
      contracts entered into in the ordinary course of business restricting the
      assignment thereof, (vi) the foregoing shall not apply to any Pipeline Company
      Borrower or its Subsidiary in connection with the issuance of debt otherwise
      permitted hereunder on market-clearing terms that are no less favorable to

      Pipeline Company Borrower or its Subsidiary than the Reference Indenture and
      (vii) clause
      (a) and (b) of this Section shall not apply to any assets that are the subject
      of an Alternate Program or to any Restricted Subsidiary whose only activities
      are to purchase receivables from a Pipeline Company Borrower or a Subsidiary
      of
      a Pipeline Company Borrower and resell such receivables, in each case pursuant
      to an Alternate Program.

      Board
      of Directors of the Company at a time when no Event of Default existed under
      this clause
      (ii); or

     

    (j)  Any
      of the
      guarantees contained in any Credit Party Guarantee, or any other material
      provision of any Loan Document, shall cease, for any reason, to be valid and
      binding upon or enforceable against any Credit Party that is a party thereto,
      or
      any such Credit Party shall so assert in writing, provided that if such
      invalidity or unenforceability is of a nature so as to be amenable to cure
      within five Business Days and if, within one Business Day after the Company
      receives notice from the Administrative Agent or the Collateral Agent or
      otherwise becomes aware that such material provision is not valid or is
      unenforceable as aforesaid, the Company delivers written notice to the
      Administrative Agent that the applicable Credit Party intends to cure such
      invalidity or unenforceability as soon as possible, then an Event of Default
      shall not exist pursuant to this paragraph
      (k) of Article 7 unless the Company or the relevant
      Credit Party shall fail to deliver or cause to be delivered an amendment or
      other modification, or other agreement or undertaking, having the same economic
      effect as the invalid or unenforceable provision within four Business Days
      after
      the delivery of such written notice of intent; or

     

    (k)  Any
      Security
      Document shall for any reason fail or cease to create a valid and enforceable
      Lien on any Collateral stated to be covered thereby or, except as permitted
      by
      the Loan Documents, such Lien shall fail or cease to be a perfected and
      first-priority (subject only to Collateral Permitted Liens) Lien, or any Credit
      Related Party shall so state in writing and, if such invalidity or lack of
      perfection or priority relates solely to Collateral with an aggregate value
      of
      $1,000,000 or less and such invalidity or lack of perfection or priority is
      such
      so as to be amenable to cure without material disadvantage to the position
      of
      the Administrative Agent, the Collateral Agent and the other Secured Parties,
      such invalidity or lack of perfection or priority shall not be cured within
      10
      days of the earlier of such Credit Related Party so stating in writing or
      delivery of notice thereof by the Administrative Agent to the Company (or such
      shorter period as shall be specified by the Administrative Agent and is
      reasonable under the circumstances);

     

    (4)  then,
      and in every
      such event (other than an event with respect to any Credit Related Party
      described in paragraph (f) of this Article except
      for clause (i)(A) thereof), and at any time
      thereafter during the continuance of such event, the Administrative Agent may,
      and at the request of the Majority Lenders shall, by notice to the Company,
      take
      either or both of the following actions, at the same or different times: (i)
      declare the Commitments to be terminated and thereupon the Commitments shall
      terminate immediately, and (ii) declare the Loans and the Notes then
      outstanding, all interest thereon and all other amounts payable under this
      Agreement to be forthwith due and payable in whole (or in part, in which case
      any principal not so declared to be due and payable may thereafter be declared
      to be due and payable), and thereupon the principal of the Loans so declared
      to
      be due and payable together with accrued interest thereon and all fees and
      other
      obligations of the Borrowers accrued hereunder, shall become due and payable
      immediately, without presentment, demand, protest or further notice of any
      kind,
      all of which are hereby expressly waived by the Borrowers; provided,
however, that if an Event of Default under paragraph (f) (except under clause (i)(A)
      thereof) shall occur, (A) the Commitments shall
      automatically terminate and (B) the principal of the Loans and the Notes then
      outstanding, together with accrued interest thereon and all fees and other
      obligations of the Borrowers accrued hereunder shall automatically become due
      and payable, without presentment, demand, protest or any notice of any kind,
      all
      of which are hereby expressly waived by the Borrowers.

      maturity, by acceleration or otherwise) of the Obligations payable by any of
      them and (ii) the prompt and complete payment by the Subsidiary Guarantors
      when
      due (whether at the stated maturity, by acceleration or otherwise) of all
      amounts payable by them under the Subsidiary Guarantee Agreement (the
      obligations described in the foregoing clauses
      (i) and (ii) being herein referred to as the “Company Guaranteed
      Obligations”).  This is a guarantee of payment and not
      collection and the liability of the Company is primary and not
      secondary.

     

    (b)  The
      guarantee
      contained in this Article 8 shall remain in full
      force and effect until the Final Payment Date, notwithstanding that from time
      to
      time during the term of this Agreement, no Company Guaranteed Obligations may
      be
      outstanding.

     

    (c)  No
      payment made by
      any Pipeline Company Borrower, any of the Subsidiary Guarantors, any other
      guarantor or any other Person, or received or collected by any Agent or any
      Lender from any Pipeline Company Borrower, any of the Subsidiary Guarantors,
      any
      other guarantor or any other Person, by virtue of any action or proceeding
      or
      any set-off or appropriation or application at any time or from time to time
      in
      reduction of or in payment of the Obligations shall be deemed to modify, reduce,
      release or otherwise affect the liability of the Company hereunder which shall,
      notwithstanding any such payment (other than any payment made by the Company
      in
      respect of the Company Guaranteed Obligations or any payment received or
      collected from the Company in respect of the Company Guaranteed Obligations),
      remain liable for the Company Guaranteed Obligations until the Final Payment
      Date.

     

    Section
      8.02.  No
      Subrogation.  Notwithstanding any payment made by any Pipeline
      Company Borrower hereunder, the Company under this Article 8 or the Parent Guarantee or any Subsidiary
      Guarantor under the Subsidiary Guarantee Agreement or any set-off or application
      of funds of any Pipeline Company Borrower or any Subsidiary Guarantor by any
      Agent or any Lender, the Company shall not be entitled to be subrogated to
      any
      of the rights of any Agent or any Lender against any Pipeline Company Borrower
      or any Subsidiary Guarantor or any collateral security or guarantee or right
      of
      offset held by any Agent or any Lender for the payment of the Company Guaranteed
      Obligations, nor shall the Company seek or be entitled to seek any contribution
      or reimbursement from any Pipeline Company Borrower or any Subsidiary Guarantor
      in respect of payments made by the Company hereunder, until the Final Payment
      Date.  If any amount shall be paid to the Company on account of such
      subrogation rights prior to the Final Payment Date, such amount shall be held
      by
      the Company in trust for the Agents and the Lenders, segregated from other
      funds
      of the Company, and shall, forthwith upon receipt by the Company, be turned
      over
      to the Administrative Agent in the exact form received by the Company (duly
      indorsed by the Company to the Administrative Agent, if required), to be applied
      against the Company Guaranteed Obligations, whether matured or unmatured),
      in
      such order as the Administrative Agent may determine but subject in any event
      to
      the terms and provisions of this Agreement and the Security
      Agreement.

     

    Section
      8.03.  Amendments,
      etc. with Respect to the Obligations.  The Company shall remain
      obligated hereunder notwithstanding that, without any reservation of rights
      against the Company and without notice to or further assent by the Company,
      any
      demand for payment of any of the Company Guaranteed Obligations made by any
      Agent or any Lender may be rescinded by such Agent or such Lender and any of
      the
      Company Guaranteed Obligations continued, and the Company Guaranteed
      Obligations, or the liability of any other Person upon or for any part thereof,
      or any collateral security or guarantee therefor or right of offset with respect
      thereto, may, from time to time, in whole or in part, be renewed, extended,
      amended, modified, accelerated, compromised, waived, surrendered or released
      by
      any Agent or any Lender, and this Agreement and the other Loan Documents and
      any
      other documents executed and delivered in connection therewith may be amended,
      modified, supplemented or terminated, in whole or in part, as the Administrative
      Agent (or the Majority Lenders or all Lenders, as the case may be) may deem
      advisable from time to time, and any collateral security, guarantee or right
      of
      offset at any time held by any Agent or any Lender for the payment of the
      Company Guaranteed Obligations may be sold, exchanged, waived, surrendered
      or
      released.  Neither the Administrative Agent, the Collateral Agent nor
      any Lender or other Secured Party shall have any obligation to protect, secure,
      perfect or insure any Lien at any time held by it as security for the Company
      Guaranteed Obligations or for the guarantee contained in this Article 8 or any property subject thereto.

     

    Section
      8.04.  Guarantee
      Absolute and Unconditional.  The Company waives any and all
      notice of the creation, renewal, extension or accrual of any of the Company
      Guaranteed Obligations and notice of or proof of reliance by any Agent or any
      Lender upon the guarantee contained in this Article
      8 or acceptance of the guarantee contained in this Article 8; the Company Guaranteed Obligations, and
      any
      of them, shall conclusively be deemed to have been created, contracted or
      incurred, or renewed, extended, amended or waived, in reliance upon the
      guarantee contained in this Article 8; and all
      dealings between the Company, any of the Pipeline Company Borrowers and any
      Subsidiary Guarantor, on the one hand, and the Agents and the Lenders, on the
      other hand, likewise shall be conclusively presumed to have been had or
      consummated in reliance upon the guarantee contained in this Article 8.  The Company waives diligence,
      presentment, protest, demand for payment and notice of default or nonpayment
      to
      or upon the Pipeline Company Borrowers or any of the Subsidiary Guarantors
      with
      respect to the Company Guaranteed Obligations.  The Company
      understands and agrees that the guarantee contained in this Article 8 shall be construed as a continuing, absolute
      and unconditional guarantee of payment without regard to (a) the validity or
      enforceability of this Agreement or any other Loan Document, any of the Company
      Guaranteed Obligations or any other collateral security therefor or guarantee
      or
      right of offset with respect thereto at any time or from time to time held
      by
      any Agent or any Lender, (b) any defense, set-off or counterclaim (other than
      a
      defense of payment or performance) which may at any time be available to or
      be
      asserted by any Pipeline Company Borrower, any Subsidiary Guarantor or any
      other
      Person against any Agent or any Lender, or (c) any other circumstance whatsoever
      (with or without notice to or knowledge of the Pipeline Company Borrowers,
      the
      Subsidiary Guarantors or the Company), other than payment or performance, which
      constitutes, or might be construed to constitute, an equitable or legal
      discharge of Pipeline Company Borrowers or the Subsidiary Guarantors for the
      Company Guaranteed Obligations, or of the Company under the guarantee contained
      in this Article 8, in bankruptcy or in any other
      instance.  When making any demand hereunder or otherwise pursuing its
      rights and remedies hereunder against the Company, any Agent or any Lender
      may,
      but shall be under no obligation to, make a similar demand on or otherwise
      pursue such rights and remedies as it may have against any Pipeline Company
      Borrower, any Subsidiary Guarantor or any other Person or against any collateral
      security or guarantee for the Company Guaranteed Obligations or any right of
      offset with respect thereto, and any failure by any Agent or any Lender to
      make
      any such demand, to pursue such other rights or remedies or to collect any
      payments from any Pipeline Company Borrower, any Subsidiary Guarantor or any
      other Person or to realize upon any such collateral security or guarantee or
      to
      exercise any such right of offset, or any release of any Pipeline Company
      Borrower, any Subsidiary Guarantor or any other Person or any such collateral
      security, guarantee or right of offset, shall not relieve the Company of any
      obligation or liability hereunder, and shall not impair or affect the rights
      and
      remedies, whether express, implied or available as a matter of law, of any
      Agent
      or any Lender against the Company.  For the purposes hereof “demand”
shall include the commencement and continuance of any legal
      proceedings.

     

    Section
      8.05.  Reinstatement.  The
      guarantee contained in this Article 8 shall continue
      to be effective, or be reinstated, as the case may be, if at any time payment,
      or any part thereof, of any of the Company Guaranteed Obligations is rescinded
      or must otherwise be restored or returned by any Agent or any Lender upon the
      insolvency, bankruptcy, dissolution, liquidation or reorganization of the
      Company, any Pipeline Company Borrower or any Subsidiary Guarantor, or upon
      or
      as a result of the appointment of a receiver, intervenor or conservator of,
      or
      trustee or similar officer for, the Company, any Pipeline Company Borrower
      or
      any Subsidiary Guarantor or any substantial part of its or their respective
      property, or otherwise, all as though such payments had not been
      made.

     

    ARTICLE
      9

    The
      Agents

     

    Each
      of the Lenders
      and each Issuing Bank hereby irrevocably appoints each of the Administrative
      Agent and the Collateral Agent as its agent and authorizes each of the
      Administrative Agent and the Collateral Agent to take such actions on its behalf
      and to exercise such powers as are delegated to the Administrative Agent and
      the
      Collateral Agent by the terms hereof and of the other Loan Documents, together
      with such actions and powers as are reasonably incidental thereto.

     

    Any
      bank serving as
      an Agent hereunder shall have the same rights and powers in its capacity as
      a
      Lender as any other Lender and may exercise the same as though it were not
      an
      Agent, and such bank and its Affiliates may accept deposits from, lend money
      to
      and generally engage in any kind of business with the Borrowers or any
      Subsidiary or other Affiliate thereof as if it were not an Agent
      hereunder.

     

    No
      Agent shall not have any duties or obligations except those expressly set forth
      herein or in the Security Agreement.  Without limiting the generality
      of the foregoing, (a) no Agent shall be subject to any fiduciary or other
      implied duties, regardless of whether a Default has occurred and is continuing,
      (b) no Agent shall have any duty to take any discretionary action or exercise
      any discretionary powers, except discretionary rights and powers expressly
      contemplated hereby that such Agent is required to exercise in writing as
      directed by the Majority Lenders (or such other number or percentage of the
      Lenders as shall be necessary under the circumstances as provided in Section 10.02), and (c) except as expressly set forth
      herein, no Agent shall have any duty to disclose, and shall not be liable for
      the failure to disclose, any information relating to the Borrowers or any of
      their Subsidiaries that is communicated to or obtained by the bank serving
      as an
      Agent or any of its Affiliates in any capacity.  No Agent shall be
      liable for any action taken or not taken by it with the consent or at the
      request of the Majority Lenders (or such other number or percentage of the
      Lenders as shall be necessary under the circumstances as provided in Section 10.02) or in the absence of its own gross
      negligence or willful misconduct.  No Agent shall be deemed to have
      knowledge of any Default unless and until written notice thereof is given to
      such Agent by a Borrower or a Lender, and no Agent shall be responsible for
      or
      have any duty to ascertain or inquire into (i) any statement, warranty or
      representation made in or in connection with this Agreement, (ii) the contents
      of any certificate, report or other document delivered hereunder or in
      connection herewith, (iii) the performance or observance of any of the
      covenants, agreements or other terms or conditions set forth herein, (iv) the
      validity, enforceability, effectiveness or genuineness of this Agreement or
      any
      other agreement, instrument or document, or (v) the satisfaction of any
      condition set forth in Article 3 or elsewhere
      herein, other than to confirm receipt of items expressly required to be
      delivered to the Administrative Agent.

     

    Each
      Agent shall be
      entitled to rely upon, and shall not incur any liability for relying upon,
      any
      notice, request, certificate, consent, statement, instrument, document or other
      writing believed by it to be genuine and to have been signed or sent by the
      proper Person.  Each Agent also may rely upon any statement made to it
      orally or by telephone and believed by it to be made by the proper Person,
      and
      shall not incur any liability for relying thereon.  Each Agent may
      consult with legal counsel (who may be counsel for a Credit Party), independent
      accountants and other experts selected by it, and shall not be liable for any
      action taken or not taken by it in accordance with the advice of any such
      counsel, accountants or experts.

     

    Any
      Agent may
      perform any and all its duties and exercise its rights and powers by or through
      any one or more sub-agents appointed by such Agent.  Any Agent and any
      such sub-agent may perform any and all its duties and exercise its rights and
      powers through their respective Related Parties.  The exculpatory
      provisions of the preceding paragraphs
      shall apply to any such sub-agent and to the Related Parties of any Agent and
      any such sub-agent, and shall apply to their respective activities in connection
      with the syndication of the credit facilities provided for herein as well as
      activities as an Agent.

     

    Subject
      to the
      appointment and acceptance of a successor Administrative Agent or Collateral
      Agent as provided in this paragraph, each of the Administrative Agent and the
      Collateral Agent may resign at any time by notifying the Lenders, each Issuing
      Bank and the Company.  Upon any such resignation, the Majority Lenders
      shall have the right, in consultation with the Company, to appoint a
      successor.  If no successor shall have been so appointed by the
      Majority Lenders and shall have accepted such appointment within 30 days after
      the retiring Agent gives notice of its resignation, then the retiring Agent
      may,
      on behalf of the Lenders and each Issuing Bank, appoint a successor Agent which
      shall be a bank with an office in New York, New York, or an Affiliate of any
      such bank.  Upon the acceptance of its appointment as Administrative
      Agent or Collateral Agent hereunder by a successor, such successor shall succeed
      to and become vested with all the rights, powers, privileges and duties of
      the
      retiring Agent, and the retiring Agent shall be discharged from its duties
      and
      obligations hereunder.  The fees payable by the Borrowers to a
      successor Agent shall be the same as those payable to its predecessor unless
      otherwise agreed between the Company and such successor.  After an
      Agent’s resignation hereunder, the provisions of this Article and Section 10.03 shall continue in effect for the benefit
      of such retiring Agent, its sub-agents and their respective Related Parties
      in
      respect of any actions taken or omitted to be taken by any of them while it
      was
      acting as Administrative Agent or Collateral Agent.

     

    Each
      Lender
      acknowledges that it has, independently and without reliance upon any Agent
      or
      any other Lender and based on such documents and information as it has deemed
      appropriate, made its own credit analysis and decision to enter into this
      Agreement.  Each Lender also acknowledges that it will, independently
      and without reliance upon any Agent or any other Lender and based on such
      documents and information as it shall from time to time deem appropriate,
      continue to make its own decisions in taking or not taking action under or
      based
      upon this Agreement, any related agreement or any document furnished hereunder
      or thereunder.

      to Article 2 unless otherwise agreed by the
      Administrative Agent and the applicable Lender.  The Administrative
      Agent or a Borrower may, in its discretion, agree to accept notices and other
      communications to it hereunder by electronic communications pursuant to
      procedures approved by it; provided that approval of such procedures
      may be limited to particular notices or communications.

     

    (c)  Any
      party hereto
      may change its address or telecopy number for notices and other communications
      hereunder by notice to the other parties hereto.  All notices and
      other communications given to any party hereto in accordance with the provisions
      of this Agreement shall be deemed to have been given and effective, if sent
      by
      mail or courier on the date of delivery thereof to the address specified herein
      for such notice, or if by telecopier when the answerback is received or if
      by
      other means, on the date of receipt; provided that a notice given by
      telecopier or electronic communication in accordance with this Section 10.01 but received on any day other than a
      Business Day or after business hours in the place of receipt, will be deemed
      to
      be received on the next Business Day in that place.

     

    Section
      10.02.  Waivers;
      Amendments.  (a) No failure or delay by any Agent, any Issuing
      Bank or any Lender in exercising any right or power hereunder shall operate
      as a
      waiver thereof, nor shall any single or partial exercise of any such right
      or
      power, or any abandonment or discontinuance of steps to enforce such a right
      or
      power, preclude any other or further exercise thereof or the exercise of any
      other right or power.  The rights and remedies of the Agents, each
      Issuing Bank and the Lenders hereunder are cumulative and are not exclusive
      of
      any rights or remedies that they would otherwise have.  No waiver of
      any provision of this Agreement or consent to any departure by any Borrower
      therefrom shall in any event be effective unless the same shall be permitted
      by
      paragraph (b) of this Section, and then such waiver
      or consent shall be effective only in the specific instance and for the purpose
      for which given.  Without limiting the generality of the foregoing,
      the making of a Loan or issuance of a Letter of Credit shall not be construed
      as
      a waiver of any Default, regardless of whether any Agent, any Lender or any
      Issuing Bank may have had notice or knowledge of such Default at the
      time.

     

    (b)  Except
      as expressly
      provided herein or in the applicable Loan Document, no provision of this
      Agreement or any other Loan Document may be waived, amended or modified, and
      no
      consent may be granted with respect to any departure by the Administrative
      Agent, any Lender or any Credit Party with respect hereto or thereto, except
      pursuant to an agreement or agreements in writing entered into by the Borrowers
      and the Majority Lenders or by the Borrowers and the Administrative Agent with
      the consent of the Majority Lenders; provided that no such waiver,
      amendment or modification of this Agreement or any other Loan Document, and
      no
      consent with respect to any departure by the Administrative Agent, any Lender,
      or any Credit Party with respect hereto or thereto, shall:

     

    (i)  increase
      the
      Commitment of any Lender, without the written consent of such
      Lender;

     

    (ii)  reduce
      or forgive
      the principal amount of any Loan or LC Disbursement or reduce the rate of
      interest thereon, or reduce any fees payable hereunder, without the written
      consent of each Lender affected thereby;

     

    (iii)  postpone
      the
      scheduled date of payment of the principal amount of any Loan or LC
      Disbursement, or any interest thereon, or any fees payable hereunder, or reduce
      the amount of, waive or excuse any such payment, or postpone the scheduled
      date
      of expiration of any Commitment, without the written consent of each Lender
      affected thereby;

     

    (iv)  issue
      any Letter of
      Credit with an expiration date, or extend the expiration date of any Letter
      of
      Credit, to a date that is later than the fifth Business Days prior to the
      Revolving Maturity Date, without the written consent of each Revolving Lender
      and the Issuing Bank of such Letter of Credit;

     

    (v)  change
Section
      2.16(b) or 2.16(c)
      in a manner that would alter the pro rata sharing of payments required thereby,
      without the written consent of each Lender;

     

    (vi)  release
      any
      Subsidiary Guarantor from its obligations under the Subsidiary Guarantee
      Agreement, without the written consent of each Lender, except in connection
      with
      the Disposition or merger of such Subsidiary Guarantor that is otherwise
      permitted hereunder;

     

    (vii)  release
      the Company
      from its guarantee obligations under Article 8,
      without the written consent of each Lender;

     

    (viii)  release
      all or
      substantially all of the Collateral, without the written consent of each Lender;
      or

     

    (ix)  change
      any of the
      provisions of this Section or the definitions of “Majority Lenders”, or any
      other provision hereof specifying the number or percentage of Lenders required
      to waive, amend or modify any rights hereunder or make any determination or
      grant any consent hereunder, without the written consent of each
      Lender;

     

    provided
      further that no such agreement shall amend, modify or otherwise affect the
      rights or duties of any Agent or any Issuing Bank hereunder or under any other
      Loan Document without the prior written consent of such Agent or such Issuing
      Bank, as the case may be.  Any such waiver and any such amendment or
      modification shall apply equally to each of the Lenders and shall be binding
      upon the Borrowers, the Lenders, the Issuing Banks and the Agents.  In
      the case of any waiver, the Borrower, the Lenders, the Issuing Banks and the
      Agents shall be restored to their former position and rights hereunder and
      under
      the other Loan Documents, and any Default or Event of Default waived shall
      be
      deemed waived ab initio and not continuing unless such waiver expressly
      provides otherwise; but no such waiver shall extend to any subsequent or other
      Default or Event of Default; and provided further that, in addition to
      Dispositions of Collateral permitted by Section
      6.04(a), the Majority Lenders may consent to additional Dispositions of
      Collateral so long as each such Disposition is for fair market value on an
      arms-length basis in a cash transaction.

     

    Section
      10.03.  Expenses;
      Indemnity; Damage Waiver.  (a) The Company shall pay (i) all
      reasonable out-of-pocket expenses incurred by the Administrative Agent and
      its
      Affiliates, including the reasonable fees, charges and disbursements of counsel
      for the Administrative Agent, in connection with the syndication of the credit
      facilities provided for herein, the preparation and administration of this
      Agreement or any amendments, modifications or waivers of the provisions hereof
      (whether or not the transactions contemplated hereby or thereby shall be
      consummated), (ii) all reasonable out-of-pocket expenses incurred by any Issuing
      Bank in connection with the issuance, amendment, renewal or extension of any
      Letter of Credit by it or any demand for payment thereunder made by such Issuing
      Bank (unless included in the fees charged separately by such Issuing Bank in
      respect of such Letter of Credit) and (iii) all out-of-pocket expenses incurred
      by any Agent, any Issuing Bank or any Lender, including the fees, charges and
      disbursements of any counsel for the Administrative Agent, any Issuing Bank
      or,
      during the continuation of any Default, any other Agent or any Lender, in
      connection with the enforcement or protection of its rights in connection with
      this Agreement, including its rights under this Section, or in connection with
      the Loans made or Letters of Credit issued hereunder, including all such
      out-of-pocket expenses incurred during  any workout, restructuring or
      negotiations in respect of such Loans or Letters of Credit.

     

    (b)  Each
      of the
      Borrowers shall indemnify, without duplication, each Agent, each Issuing Bank
      and each Lender, and each Related Party of any of the foregoing Persons (each
      such Person being called an “Indemnitee”) against, and hold
      each Indemnitee harmless from, any and all losses, claims, damages, liabilities
      and related expenses, including the fees, charges and disbursements of any
      counsel for any Indemnitee, incurred by or asserted against any Indemnitee
      arising out of, in connection with, or as a result of (i) the execution or
      delivery of this Agreement or any agreement or instrument contemplated hereby,
      the performance by the parties hereto of their respective obligations hereunder
      or the consummation of the Transactions or any other transactions contemplated
      hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom
      (including any refusal by the applicable Issuing Bank to honor a demand for
      payment under a Letter of Credit issued by it in accordance with applicable
      law
      if the documents presented in connection with such demand do not strictly comply
      with the terms of such Letter of Credit), (iii) any actual or alleged presence
      or release of Hazardous Materials on or from any property owned or operated
      by
      the Company or any of its Subsidiaries, or any Environmental Liability related
      in any way to the Company or any of its Subsidiaries, or (iv) any actual or
      prospective claim, litigation, investigation or proceeding relating to any
      of
      the foregoing, whether based on contract, tort or any other theory and
      regardless of whether any Indemnitee is a party thereto; provided that
      such indemnity shall not, in any of the foregoing circumstances as to any
      Indemnitee, be available to the extent that such losses, claims, damages,
      liabilities or related expenses (i) are determined by a court of competent
      jurisdiction by final and nonappealable judgment to have resulted from or to
      have been attributable to the gross negligence or willful misconduct of such
      Indemnitee or its employees or agents or (ii) have arisen from a dispute between
      or among the Arrangers, the Administrative Agent or the Lenders or from a claim
      of an Indemnitee against another Indemnitee which in either case is not a direct
      or indirect result of any act or omission of the Borrowers or any of their
      subsidiaries.  The indemnification provisions of this Section 10.03(b) are not intended to constitute a
      guaranty of payment of any principal, interest, facility or commitment fees,
      rental or other lease payments, or analogous amounts, under the Loans or any
      other Secured Obligations; provided that nothing in this Section 10.03(b) shall limit the liability of any
      Borrower for the payment of the Loans or any Secured Obligations, which
      liability arises under any other Loan Document, including any liability arising
      under this Agreement.

     

    (c)  To
      the extent that
      any Borrower fails to pay any amount required to be paid by it to any Agent
      or
      any Issuing Bank under paragraph (a) or (b) of this Section,
      each Lender severally agrees to
      pay to such Agent or such Issuing Bank, as the case may be, such Lender’s pro
      rata share (determined as of the time that the applicable unreimbursed expense
      or indemnity payment is sought based on the Commitments at such time, or if
      the
      Commitments have terminated or expired, based on the Credit Exposures at such
      time) of such unpaid amount; provided that the unreimbursed expense or
      indemnified loss, claim, damage, liability or related expense, as the case
      may
      be, was incurred by or asserted against such Agent or such Issuing Bank in
      its
      capacity as such.

     

    (d)  To
      the extent
      permitted by applicable law, the Borrowers shall not and each Indemnitee, by
      its
      acceptance of any right to or benefit of indemnification under this Agreement
      and as a condition to its rights to and benefits of indemnification provided
      for
      herein, agrees that it shall not, assert, and hereby waives, any claim against
      any Indemnitee or any Borrower, respectively, on any theory of liability, for
      special, indirect, consequential or punitive damages (as opposed to direct
      or
      actual damages) arising out of, in connection with, or as a result of, this
      Agreement or any agreement or instrument contemplated hereby, the Transactions,
      any Loan or Letter of Credit or the use of the proceeds thereof.

     

    (e)  All
      amounts due
      under this Section shall be payable not later than 30 days after the delivery
      of
      written demand to the Company therefor.

     

    Section
      10.04.  Successors
      and Assigns.  (a)  The provisions of this Agreement
      shall be binding upon and inure to the benefit of the parties hereto and their
      respective successors and assigns permitted hereby (including any Affiliate
      of
      an Issuing Bank that issues any Letter of Credit), except that (i) the Borrowers
      may not assign or otherwise transfer any of their respective rights or
      obligations hereunder in a transaction not permitted hereunder without the
      prior
      written consent of each Lender (and any attempted assignment or transfer by
      any
      Borrower without such consent shall be null and void), and (ii) no Lender may
      assign or otherwise transfer its rights or obligations hereunder except in
      accordance with this Section.  Nothing in this Agreement, expressed or
      implied, shall be construed to confer upon any Person (other than the parties
      hereto, their respective successors and assigns permitted hereby (including
      any
      Affiliate of an Issuing Bank that issues any Letter of Credit), Participants
      (to
      the extent provided in paragraph (c) of this
      Section) and, to the extent expressly contemplated hereby, the Related Parties
      of each of the Administrative Agent, each Issuing Bank and the Lenders) any
      legal or equitable right, remedy or claim under or by reason of this
      Agreement.

     

    (b)  (i)
      Subject to the
      conditions set forth in paragraph (b)(ii) below, any Lender
      may assign to one or more
      assignees all or a portion of its rights and obligations under this Agreement
      (including all or a portion of its Commitment and its Loans (if any)) with
      the
      prior written consent (such consent not to be unreasonably withheld or delayed)
      of:

     

    (A)  the
      Company,
provided that no consent of the Company shall be required for an
      assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined
      below) or, if an Event of Default has occurred and is continuing, any other
      assignee; and

     

    (B)  the
      Administrative
      Agent; and

     

    (C)  each
      Issuing
      Bank.

     

    (ii)  Assignments
      shall
      be subject to the following additional conditions:

     

    (A)  except
      (i) in the
      case of an assignment to a Lender or an Affiliate of a Lender or an Approved
      Fund or an assignment of the entire remaining amount of the assigning Lender’s
      Commitment (or, if the applicable Commitment is not then in effect, the
      outstanding principal balance of the Loans of the assigning Lender subject
      to
      each such assignment) or (ii) if each of the Company (unless an Event of Default
      has occurred and is continuing) and the Administrative Agent otherwise consent,
      the amount of the Commitment (or, if the applicable Commitment is not then
      in
      effect, the outstanding principal balance of the Loans) of the assigning Lender
      subject to each such assignment (determined as of the date the Assignment and
      Assumption with respect to such assignment is delivered to the Administrative
      Agent) shall be $5,000,000 or any increment of $1,000,000 in excess thereof;
      provided that related Approved Funds shall be aggregated for purposes
      of such minimum assigned amount;

     

    (B)  each
      partial
      assignment shall be made as an assignment of a proportionate part of all the
      assigning Lender’s rights and obligations under this Agreement;

     

    (C)  the
      parties to each
      assignment shall execute and deliver to the Administrative Agent an Assignment
      and Assumption, together with a processing and recordation fee of $3,500;
provided that only one such fee shall be payable in connection with
      simultaneous assignments to or by two or more related Approved
      Funds;

     

    (D)  the
      assignee, if it
      shall not be a Lender, shall deliver to the Administrative Agent an
      Administrative Questionnaire in which the assignee designates one or more
      individuals (each such individual, a “Credit Contact”) to whom
      all syndicate-level information (which may contain material non-public
      information about the Borrowers, the Credit Parties and their Related Parties
      or
      their respective securities) will be made available and who may receive such
      information in accordance with the assignee’s compliance procedures and
      applicable laws, including Federal and state securities laws; and

     

    (E)  in
      the case of an
      assignment by a Lender to a CLO (as defined below) managed or administered
      by
      such Lender or an Affiliate of such Lender, the assigning Lender shall retain
      the sole right to approve any amendment, modification or waiver of any provision
      of this Agreement, provided that the Assignment and Assumption between
      such Lender and such CLO may provide that such Lender will not, without the
      consent of such CLO, agree to any amendment, modification or waiver described
      in
      the first proviso to Section 10.02(b) that affects
      such CLO.

     

    For
      the purposes of
      this Section 10.04(b), the terms “Approved Fund” and
“CLO” have the following meanings:

     

    “Approved
      Fund” means, with respect to any Lender, (a) a CLO managed or
      administered by such Lender or an Affiliate of such Lender and (b) with respect
      to any Lender that is a fund which invests in bank loans and similar extensions
      of credit, any other fund that invests in bank loans and similar extensions
      of
      credit and is managed by the same investment advisor as such Lender or by an
      Affiliate of such investment advisor.

     

    “CLO”
      means, with respect to any Lender, any entity (whether a corporation,
      partnership, trust or otherwise) that is engaged in making, purchasing, holding
      or otherwise investing in bank loans and similar extensions of credit in the
      ordinary course and is administered or managed by such Lender or an Affiliate
      of
      such Lender.

     

    (iii)  Subject
      to
      execution and delivery thereof and acceptance and recording thereof pursuant
      to
      paragraph (b)(iv) of
      this Section, from and after the effective date specified in each Assignment
      and
      Assumption the assignee thereunder shall be a party hereto and, to the extent
      of
      the interest assigned by such Assignment and Assumption, have the rights and
      obligations of a Lender under this Agreement, and the assigning Lender
      thereunder shall, to the extent of the interest assigned by such Assignment
      and
      Assumption, be released from its obligations under this Agreement (and, in
      the
      case of an Assignment and Assumption covering all of the assigning Lender’s
      rights and obligations under this Agreement, such Lender shall cease to be
      a
      party hereto but shall continue to be entitled to the benefits of Sections
2.13, 2.14, 2.15
      and 10.03).  Any assignment or transfer by a
      Lender of rights or obligations under this Agreement that does not comply with
      this Section 10.04 shall be treated for purposes of
      this Agreement as a sale by such Lender of a participation in such rights and
      obligations in accordance with paragraph (c) of this
      Section.

     

    (iv)  The
      Administrative
      Agent, acting for this purpose as an agent of the Borrowers, shall maintain
      at
      one of its offices a copy of each Assignment and Assumption delivered to it
      and
      a register for the recordation of the names and addresses of the Lenders, and
      the Commitment of, and principal amount of the Loans and LC Disbursements owing
      to, each Lender pursuant to the terms hereof from time to time (the
“Register”).  The entries in the Register as to the
      identity of the Lenders shall be conclusive, and as to the other items referred
      to above shall be conclusive absent manifest error, and the Borrowers, the
      Administrative Agent, each Issuing Bank and the Lenders may treat each Person
      whose name is recorded in the Register pursuant to the terms hereof as a Lender
      hereunder for all purposes of this Agreement, notwithstanding notice to the
      contrary.  The Register shall be available for inspection by the
      Company, any Issuing Bank and any Lender, at any reasonable time and from time
      to time upon reasonable prior notice.

     

    (v)  Upon
      its receipt of
      a duly completed Assignment and Assumption executed by an assigning Lender
      and
      an assignee, the assignee’s completed Administrative Questionnaire (unless the
      assignee shall already be a Lender hereunder), the processing and recordation
      fee referred to in paragraph (b) of this Section and
      any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall
      accept such Assignment and Assumption and record the information contained
      therein in the Register.  No assignment shall be effective for
      purposes of this Agreement unless it has been recorded in the Register as
      provided in this paragraph.

     

    (c)  Any
      Lender may,
      without the consent of the Borrowers, the Administrative Agent, or any Issuing
      Bank, sell participations to one or more banks or other entities (a
“Participant”) in all or a portion of such Lender’s rights and
      obligations under this Agreement (including all or a portion of its Commitment
      and the Loans owing to it and Notes held by it); provided that (A) such
      Lender’s obligations under this Agreement shall remain unchanged, (B) such
      Lender shall remain the holder of its Notes (if any) for all purposes of this
      Agreement and shall remain solely responsible to the other parties hereto for
      the performance of such obligations and (C) the Borrowers, the Administrative
      Agent, each Issuing Bank and the other Lenders shall continue to deal solely
      and
      directly with such Lender in connection with such Lender’s rights and
      obligations under this Agreement.  Any agreement or instrument
      pursuant to which a Lender sells such a participation shall provide that such
      Lender shall retain the sole right to enforce this Agreement and to approve
      any
      amendment, modification or waiver of any provision of this Agreement;
provided that such agreement or instrument may provide that such Lender
      will not, without the consent of the Participant, agree to any amendment,
      modification or waiver described in the first proviso to Section 10.02(b) that affects such
      Participant.  Subject to paragraph (d) of
      this Section, the Borrowers agree that each Participant shall be entitled to
      the
      benefits of Sections 2.13, 2.14 and 2.15
      with respect
      to its participations hereunder to the same extent as if it were a Lender and
      had acquired its interest by assignment pursuant to paragraph (b) of this Section and provided that such
      Participant shall have complied with any obligation in respect thereof that
      it
      would have had as a Lender.  To the extent permitted by law, each
      Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender,
provided such Participant agrees to be subject
      to Section 2.16(c) as though it were a
      Lender.

     

    (d)  A
      Participant shall
      not be entitled to receive any greater payment under Section 2.13 or 2.15 than the
      applicable Lender would have been entitled to receive with respect to the
      participation sold to such Participant, unless the sale of the participation
      to
      such Participant is made with the Company’s prior written consent.  A
      Participant that would be a Foreign Lender if it were a Lender shall not be
      entitled to the benefits of Section 2.15 unless the
      Company is notified of the participation sold to such Participant and such
      Participant agrees, for the benefit of the Borrowers, to comply with Section 2.15(e) and (f) as
      though it were a Lender.

     

    (e)  Any
      Lender may at
      any time pledge or assign a security interest in all or any portion of its
      rights under this Agreement to secure obligations of such Lender, including
      any
      pledge or assignment to secure obligations to a Federal Reserve Bank, and this
      Section shall not apply to any such pledge or assignment of a security interest;
      provided that no such pledge or assignment of a security interest shall
      release a Lender from any of its obligations hereunder or substitute any such
      pledgee or assignee for such Lender as a party hereto.

     

    Section
      10.05.  Survival.  All
      covenants, agreements, representations and warranties made by the Borrowers
      herein and in the certificates or other instruments  delivered in
      connection with or pursuant to this Agreement shall be considered to have been
      relied upon by the other parties hereto and shall survive the execution and
      delivery of this Agreement and the making of any Loans and issuance of any
      Letters of Credit, regardless of any investigation made by any such other party
      or on its behalf and notwithstanding that the Administrative Agent, any Issuing
      Bank or any Lender may have had notice or knowledge of any Default or incorrect
      representation or warranty at the time any credit is extended hereunder, and
      shall continue in full force and effect as of the date made, or any date
      referred to therein, as applicable, (but without being deemed remade on or
      as of
      any subsequent date by reason of this Section 10.05)
      as long as the principal of or any accrued interest on any Loan or any fee
      or
      any other amount payable under this Agreement is outstanding and unpaid or
      any
      Letter of Credit is outstanding and so long as the Commitments have not expired
      or terminated.  The provisions of Sections 2.13, 2.14, 2.15
      and 10.03 and Article 9 shall survive and
      remain in full force and
      effect regardless of the consummation of the transactions contemplated hereby,
      the repayment of the Loans, the expiration or termination of the Letters of
      Credit and the Commitments or the termination of this Agreement or any provision
      hereof.

     

    Section
      10.06.  Counterparts;
      Integration; Effectiveness.  This Agreement may be executed in
      counterparts (and by different parties hereto on different counterparts), each
      of which shall constitute an original, but all of which when taken together
      shall constitute a single contract.  This Agreement and the other Loan
      Documents and any separate letter agreements with respect to fees payable to
      the
      Administrative Agent constitute the entire contract among the parties relating
      to the subject matter hereof and supersede any and all previous agreements
      and
      understandings, oral or written, relating to the subject matter
      hereof.  Except as provided in Section
      3.01, this Agreement shall become effective when it shall have been executed
      by the Administrative Agent and when the Administrative Agent shall have
      received counterparts hereof which, when taken together, bear the signatures
      of
      each of the other parties hereto, and thereafter shall be binding upon and
      inure
      to the benefit of the parties hereto and their respective successors and
      assigns.  Delivery of an executed counterpart of a signature page of
      this Agreement by telecopy shall be effective as delivery of a manually executed
      counterpart of this Agreement.

     

    Section
      10.07.  Severability.  To
      the fullest extent permitted by applicable law any provision of this Agreement
      held to be invalid, illegal or unenforceable in any jurisdiction shall, as
      to
      such jurisdiction, be ineffective to the extent of such invalidity, illegality
      or unenforceability without affecting the validity, legality and enforceability
      of the remaining provisions hereof; and the invalidity of a particular provision
      in a particular jurisdiction shall not invalidate such provision in any other
      jurisdiction.

     

    Section
      10.08.  Right
      of Setoff.  If an Event of Default shall have occurred and be
      continuing, subject to the terms and provisions of the Security Agreement and
      the other Loan Documents, each Lender and each of its Affiliates is hereby
      authorized at any time and from time to time, to the fullest extent permitted
      by
      law, to set off and apply any and all deposits (general or special, time or
      demand, provisional or final) at any time held and other obligations at any
      time
      owing by such Lender or Affiliate to or for the credit or the account of a
      Borrower against any of and all the obligations of such Borrower now or
      hereafter existing under this Agreement held by such Lender, irrespective of
      whether or not such Lender shall have made any demand under this Agreement
      and
      although such obligations may be unmatured.  The rights of each Lender
      under this Section are in addition to other rights and remedies (including
      other
      rights of setoff) which such Lender may have but are subject to the terms and
      provisions of the Security Agreement and the other Loan Documents.

     

    Section
      10.09.  Governing
      Law; Jurisdiction; Consent to Service of
      Process.  (a)  This Agreement shall be construed in
      accordance with and governed by the law of the State of New York.

     

    (b)  Each
      Borrower
      hereby irrevocably and unconditionally submits, for itself and its property,
      to
      the nonexclusive jurisdiction of the Supreme Court of the State of New York
      sitting in New York County and of the United States District Court of the
      Southern District of New York, and any appellate court from any thereof, in
      any
      action or proceeding by the Administrative Agent, the Collateral Agent any
      Issuing Bank or any Lender arising out of or relating to this Agreement, or
      for
      recognition or enforcement of any judgment obtained in any such action or
      proceeding, and each of the parties hereto hereby irrevocably and
      unconditionally agrees that all claims in respect of any such action or
      proceeding may be heard and determined in such New York State or, to the extent
      permitted by law, in such Federal court.  Each of the parties hereto
      agrees that a final judgment in any such action or proceeding shall be
      conclusive and may be enforced in other jurisdictions by suit on the judgment
      or
      in any other manner provided by law.  Nothing in this Agreement shall
      affect any right that the Administrative Agent, any Issuing Bank or any Lender
      may otherwise have to bring any action or proceeding relating to this Agreement
      against any Borrower or its properties in the courts of any
      jurisdiction.

     

    (c)  Each
      Borrower
      hereby irrevocably and unconditionally waives, to the fullest extent it may
      legally and effectively do so, any objection which it may now or hereafter
      have
      to the laying of venue of any suit, action or proceeding arising out of or
      relating to this Agreement in any court referred to in paragraph (b) of this Section.  Each of the parties
      hereto hereby irrevocably waives, to the fullest extent permitted by law, the
      defense of an inconvenient forum to the maintenance of such action or proceeding
      in any such court.

     

    (d)  Each
      party to this
      Agreement irrevocably consents to service of process in any action or proceeding
      referred to in Section 10.09 by the mailing thereof
      by certified mail, return receipt requested, addressed as provided in Section 10.01(a), with a copy thereof to the “General
      Counsel” of such Person at such same address.

     

    Section
      10.10.  Waiver
      Of Jury Trial.  EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST
      EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY
      IN
      ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
      AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,
      TORT OR ANY OTHER THEORY).  EACH PARTY HERETO (a) CERTIFIES THAT NO
      REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
      OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION,
      SEEK
      TO ENFORCE THE FOREGOING WAIVER, AND (b) ACKNOWLEDGES THAT IT AND THE OTHER
      PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
      THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     

    Section
      10.11.  Headings.  Article
      and Section headings and the Table of Contents used herein are for convenience
      of reference only, are not part of this Agreement and shall not affect the
      construction of, or be taken into consideration in interpreting, this
      Agreement.

     

    Section
      10.12.  Confidentiality.  Each
      of the Administrative Agent, the Collateral Agent, each Issuing Bank and the
      Lenders agrees to maintain the confidentiality of the Information (as defined
      below), except that Information may be disclosed (a) to its and its Affiliates’
directors, officers, employees and agents, including accountants, legal counsel
      and other advisors involved in the financing provided for herein (it being
      understood that the Persons to whom such disclosure is made will be informed
      of
      the confidential nature of such Information and instructed to keep such
      Information confidential), (b) to the extent requested by any regulatory
      authority, (c) to the extent required by applicable laws or regulations or
      by
      any subpoena or similar legal process, applicable to it, (d) to any other party
      to this Agreement, (e) in connection with the exercise of any remedies hereunder
      or any suit, action or proceeding relating to this Agreement or the enforcement
      of rights hereunder, (f) subject to an agreement to comply with the provisions
      of this Section 10.12 or a separate agreement
      containing provisions substantially the same as those of this Section, to (i)
      any assignee of or Participant in, or any prospective assignee of or Participant
      in, any of its rights or obligations under this Agreement, (ii) any pledgee
      referred to in Section 10.04(e) or (iii) any actual
      or prospective counterparty (or its advisors) to any swap or derivative
      transaction relating to any Borrower and its obligations, (g) with the consent
      of a Borrower or (h) to the extent such Information (i) becomes publicly
      available other than as a result of a breach of this Section or (ii) becomes
      available to the Administrative Agent, the Collateral Agent, any Issuing Bank
      or
      any Lender on a nonconfidential basis from a source other than a Borrower or
      any
      of its Subsidiaries, the Administrative Agent, the Collateral Agent, any Issuing
      Bank or any other Lender.  For the purposes of this Section,
“Information” means all information received from a Borrower or
      any of its Subsidiaries relating to any Borrower or any of its Subsidiaries
      or
      its businesses, other than any such information that is available to the
      Administrative Agent, the Collateral Agent, any Issuing Bank or any Lender
      on a
      nonconfidential basis prior to disclosure by such Borrower; provided
      that, in the case of information received from a Borrower after the date hereof,
      such information is clearly identified at the time of delivery as
      confidential.  Any Person required to maintain the confidentiality of
      Information as provided in this Section shall be considered to have complied
      with its obligation to do so if such Person has exercised the same degree of
      care to maintain the confidentiality of such Information as such Person would
      accord to its own confidential information; and nothing in the foregoing
      authorization shall apply to any disclosure that would constitute a violation
      of
      applicable federal and state securities laws.

     

    EACH
      LENDER
      ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 10.12 FURNISHED TO IT
      PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION
      CONCERNING THE BORROWERS AND ITS AFFILIATES AND  THEIR RELATED PARTIES
      OR THEIR RESPECTIVE SECURITIES, AND CONFIRMS THAT IT HAS DEVELOPED COMPLIANCE
      PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT
      WILL
      HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES
      AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES
      LAWS.

     

    ALL
      INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE
      BORROWERS OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF
      ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY
      CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT THE BORROWER, CREDIT PARTIES
      AND
      THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES.  ACCORDINGLY,
      EACH LENDER REPRESENTS TO THE BORROWER AND THE ADMINISTRATIVE AGENT THAT IT
      HAS
      IDENTIFIED IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE
      INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE
      WITH
      ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE
      SECURITIES LAWS.

     

    Section
      10.13.  Security
      Agreement.  Each of the Lenders, for itself and for each of its
      Affiliates, and each Issuing Bank hereby (i) approves the Security Agreement
      and
      (ii) irrevocably authorizes and directs the Collateral Agent, and any successor
      thereof appointed pursuant to Article 9, to take
      such actions on its behalf and to exercise such powers as are delegated to
      the
      Collateral Agent by the terms of the Security Agreement, together with such
      actions and powers as are reasonably incidental thereto.  The
      Collateral Agent is hereby authorized and directed to execute and deliver the
      Security Agreement on behalf of the Lenders.  Until the Final Payment
      Date shall have occurred, to the extent the Security Agreement amends, modifies
      or supplements any term or provision hereof, it shall constitute an amendment
      and modification to, and supplement of, this Agreement.  Each Lender
      that is now, or hereafter becomes, a party to this Agreement (including each
      Person that becomes a Lender pursuant to Section
      10.04) and each Person (including any Affiliate of a Lender that party to
      any Secured Hedging Agreement) otherwise claiming rights pursuant to this
      Agreement (a) consents to the provisions of the Security Agreement and (b)
      agrees by being or becoming a Lender hereunder or otherwise claiming any such
      rights, to become or be bound by the Security Agreement and each other document
      entered into by the Administrative Agent on behalf of the Secured Parties
      pursuant to the terms and provisions of the Security Agreement.

     

    Section
      10.14.  Amendment
      and Restatement and Continuing Effect.  This Agreement
      constitutes for all purposes an amendment and a restatement of the Existing
      Facility and as of the Effective Date all commitments or loans outstanding,
      or
      any letter of credit issued, under the Existing Facility shall constitute
      Commitments and Letters of Credit under this Agreement.  The Existing
      Facility, as amended and restated hereby, continues in full force and effect
      as
      so amended and restated by this Agreement.

     

    Section
      10.15.  USA
      Patriot Act.  Each Lender hereby notifies the Borrower that
      pursuant to the requirements of the Patriot Act, it is required to obtain,
      verify and record information that identifies the Borrower, which information
      includes the name and address of the Borrower and other information that will
      allow such Lender to identify the Borrower in accordance with the Patriot
      Act.

     

    Section
      10.16.  Releases.  (a)
      On the Effective Date, without further action by any party to the Loan
      Documents, (i) each Subsidiary listed on Schedule 10.16(a) (the
“Released Parties”) shall cease to be a Subsidiary Guarantor or
      a Borrower, (ii) each of the Released Parties shall cease to be a “Grantor”
under the Security Agreement, (iii) any property of a Released Party in which
      a
      security interest is granted by such Released Party pursuant to the Security
      Documents shall be released from such security interest and shall no longer
      constitute Collateral and (iv) the Released Parties shall cease to be parties
      to
      the Loan Documents or to have any rights or obligations thereunder.

     

    (b)  The
      Administrative
      Agent shall (i) from time to time upon the reasonable request of the Company,
      at
      the sole expense of the Company, execute and deliver to the Company such
      instruments and documents as the Company may reasonably request to fully effect
      solely the foregoing releases, terminations and discharges, and (ii) return
      to
      the Company any certificate or other instruments delivered to the Administrative
      Agent in connection with the Existing Credit Agreement and Security Documents
      all security interests in which are released pursuant to Section 10.16(a).
