        WHEREAS,
          pursuant to the Agreement and Plan of Merger (as amended, supplemented

        WHEREAS,
          to fund, in part, the Merger Funds, it is intended that the Sponsors and
          certain
          other investors (collectively, the “Initial Investors”) will
          directly or indirectly make cash equity contributions (the “Equity
          Contribution”) to Holdings and/or a direct or indirect parent thereof
          in exchange for Stock (which cash will be contributed to Merger Sub in

          for common stock of Merger Sub) in an aggregate amount equal to, when combined
          with the fair market value of the Stock of management and existing shareholders
          of the Parent rolled over or invested in connection with the Transactions,
          at
          least 15% (the “Minimum Equity Amount”) of the total sources
          (including the Existing Notes, the Existing Parent Notes and the Existing
          Oncor
          Notes, but excluding any transition bonds) required to consummate the Merger
          (the “Merger Consideration”), to redeem, refinance or repay
          certain existing indebtedness or repurchase receivables of the Parent and
          its
          Subsidiaries, including the Repaid Indebtedness (the

          in connection with the Transactions (such fees, premiums and expenses,
          together
          with the Merger Consideration and the Refinancing payment, the “Merger
          Funds”);

         

        WHEREAS,
          in order to fund, in part, the Merger Funds, (a) the Borrower will borrow
          on the Closing Date $6,750,000,000 in aggregate principal amount of senior
          unsecured interim loans (the “Borrower Senior Interim Loans”)
          under the Borrower Senior Interim Loan Agreement and (b) the Parent will
          borrow on the Closing Date $4,500,000,000 in aggregate principal amount
          of
          senior unsecured interim loans (the “Parent Senior Interim

        WHEREAS,
          in connection with the foregoing, the Borrower has requested that the Lenders
          extend credit to the Borrower in the form of (a) $16,450,000,000 in aggregate

        available
          to the Borrower on the Closing Date and at any time and from time to time
          prior
          to the Delayed Draw Term Loan Commitment Termination Date (the “Delayed
          Draw Term Loan Facility”) with approximately $2,150,000,000 of such
          amount to be borrowed on the Closing Date, (c) $1,250,000,000 in aggregate

          Credit
          Termination Date (the “Revolving Credit
          Facility”);

         

        WHEREAS,
          in connection with the foregoing, the Borrower has requested that the Lenders
          extend credit to the Borrower in the form of a revolving credit facility,
          the
          aggregate principal amount of which is capped by the MTM Exposure (the
          “Posting Facility”);

         

        WHEREAS,
          the proceeds of (a) the Initial Term Loans less $400,000,000 and (b) up
          to $250,000,000 of Revolving Credit Loans will be used by the Borrower,
          together
          with (i) the net proceeds of the Borrower Senior Interim Loans and (ii)
          cash on hand at the Borrower, to provide to the Parent a portion of the
          Merger
          Funds.  Up to $400,000,000 of proceeds of the Initial Term Loans will
          be used by the Borrower for general corporate purposes.  The proceeds
          of the Delayed Draw Term Loans will be used by the Borrower on and after
          the
          Closing Date for the purpose of funding the construction, engineering,
          design,
          improvement, testing, start-up, retesting, operation, repair, maintenance
          and
          development costs and other Capital Expenditures (including Environmental
          CapEx), interest during construction and related fees and expenses in connection
          with the construction of Oak Grove Unit 1, Oak Grove Unit 2 and Sandow
          Unit 5
          and environmental upgrades to the Borrower’s and its Subsidiaries’ existing
          power generation facilities (collectively, the “New Build
          Program”).  The proceeds of Revolving Credit Loans and
          Swingline Loans will be used by the Borrower on or after the Closing Date
          for
          working capital requirements and other general corporate purposes (including
          the
          financing of any acquisitions permitted hereunder and the provision of
          collateral support in respect of Commodity Hedging Agreements, including
          for the
          avoidance of any doubt, any speculative Commodity Hedging
          Agreements).  The proceeds of the Deposit L/C Loans shall be deposited
          into the Deposit L/C Loan Collateral Account for the purpose of cash
          collateralizing the Borrower’s obligations to the Deposit Letter of Credit
          Issuer in respect of Deposit Letters of Credit.  The Letters of Credit
          will be used by the Borrower for general corporate purposes (including
          the
          provision of collateral support in respect of Commodity Hedging Agreements,
          including, for the avoidance of any doubt, speculative Commodity Hedging
          Agreements).  The proceeds of the Posting Advances will be used by the
          Borrower (a) to fund margin payments on over-the-counter natural gas fixed
          for
          floating swap transactions between the Borrower and the Restricted Subsidiaries,
          on the one hand, and various counterparties, on the other, (b) to fund
          margin payments on NYMEX futures and swap positions maintained by the Borrower
          and the Restricted Subsidiaries and (c) for other general corporate
          purposes of the Borrower and its Subsidiaries (provided that such funds
          will be
          applied first to fund margin on Dealer Swaps to the extent such transactions
          are
          outstanding and any margin is due thereon and second for any of such other
          purposes); and

         

        WHEREAS,
          the Lenders and Letter of Credit Issuers are willing to make available
          to the
          Borrower such loans and facilities upon the terms and subject to the conditions
          set forth herein;

         

        AGREEMENT:

         

        NOW,
          THEREFORE, in consideration of the premises and the covenants and agreements
          contained herein, the parties hereto hereby agree as follows:

         

        SECTION
          1.                           Definitions.

         

        

         

        1.1.           Defined
          Terms

         

        .

         

        
          
             

          

          
            -2-

            
              

            

          

          
             

          

        

        (a)           As
          used herein, the following terms shall have the meanings specified in this
          Section 1.1 unless the context otherwise requires:

         

        “ABR”
          shall mean for any day a fluctuating rate per annum equal to the higher
          of
          (a) the Federal Funds Effective Rate plus 1/2 of 1% and (b) the
          rate of interest in effect for such day as publicly announced from time
          to time
          by the Administrative Agent as its “prime rate”.  The “prime rate” is
          a rate set by the Administrative Agent based upon various factors including
          the
          Administrative Agent’s costs and desired return, general economic conditions and
          other factors, and is used as a reference point for pricing some loans,
          which
          may be priced at, above, or below such announced rate.  If the
          Administrative Agent is unable to ascertain the Federal Funds Effective
          Rate due
          to its inability to obtain sufficient quotations in accordance with the
          definition thereof, after notice is provided to the Borrower, the ABR shall
          be
          determined without regard to clause (a) above until the circumstances giving
          rise to such inability no longer exist.  Any change in the ABR due to
          a change in such rate announced by the Administrative Agent or in the Federal
          Funds Effective Rate shall take effect at the opening of business on the
          day
          specified in the public announcement of such change.

         

        “ABR
          Loan” shall mean each Loan bearing interest based on the ABR and, in
          any event, shall include all Swingline Loans.

         

        “Acceptable
          Reinvestment Commitment” shall mean a binding commitment of the
          Borrower or any Restricted Subsidiary entered into at any time prior to
          the end
          of the Reinvestment Period to reinvest the proceeds of a Prepayment
          Event.

         

        “Acquired
          EBITDA” shall mean, with respect to any Acquired Entity or Business or
          any Converted Restricted Subsidiary (any of the foregoing, a “Pro Forma

          the

          of the
          same Type and (iv) may be repaid or prepaid in accordance with the provisions
          hereof, but once repaid or prepaid may not be reborrowed.

         

        (d)           Subject
          to and upon the terms and conditions herein set forth, each Lender having

          Revolving Credit Commitment severally, but not jointly, agrees to make
          a loan or

          exceeding such Lender’s Revolving Credit Commitment at suchtime, (E) shall
          not, after giving effect thereto and to the application of the proceeds
          thereof,
          result at any time in the aggregate amount of the Lenders’ Revolving Credit
          Exposures at such time exceeding the Total Revolving Credit Commitment
          then in
          effect, and (F) shall not exceed $250,000,000 in Revolving Credit Loans
          in the
          aggregate on the Closing Date to fund the Merger Funds.

         

        (e)           (1)  Subject
          to and upon the terms and conditions herein set forth, the Swingline Lender
          in
          its individual capacity agrees, at any time and from time to time on and
          after
          the Closing Date and prior to the Swingline Maturity Date, to make a loan
          or
          loans (each a “Swingline Loan” and, collectively, the
“Swingline Loans”) in Dollars to the Borrower, which
          Swingline
          Loans (i) shall be ABR Loans, (ii) shall have the benefit of the
          provisions of Section 2.1(e)(ii), (iii) shall not exceed at any time

          exceeding the Total Revolving Credit Commitment then in effect and (v) may
          be repaid and reborrowed in accordance with the provisions
          hereof.  The Swingline Lender shall not make any Swingline Loan after
          receiving a written notice from the Borrower or the Required Lenders stating
          that a Default or Event of Default exists and is continuing until such
          time as
          the Swingline Lender shall have received written notice (i) of rescission
          of all such notices from the party or parties originally delivering such
          notice
          or (ii) of the waiver of such Default or Event of Default in accordance
          with the provisions of Section 13.1 or (iii) that such Default or
          Event of Default is no longer continuing.

        (ii)           On
          any Business Day, the Swingline Lender may, in its sole discretion, give
          notice
          to the Revolving Credit Lenders, with a copy to the Borrower and the
          Administrative Agent, that all then-outstanding Swingline Loans shall be
          funded
          with a Borrowing of Revolving Credit Loans, in which case Revolving Credit
          Loans
          constituting ABR Loans (each such Borrowing, a “Mandatory
          Borrowing”) shall be made on the immediately succeeding Business Day by
          all Revolving Credit Lenders prorata based on each such
          Lender’s Revolving Credit Commitment Percentage, and the proceeds thereof shall
          be applied directly to the Swingline Lender to repay the Swingline Lender
          for
          such outstanding Swingline Loans.  Each Revolving Credit Lender hereby
          irrevocably agrees to make such Revolving Credit Loans upon one Business
          Day’s
          notice pursuant to each Mandatory Borrowing in the amount and in the manner
          specified in the preceding sentence and on the date specified to it in
          writing
          by the Swingline Lender notwithstanding (i) that the amount of the Mandatory
          Borrowing may not comply with the minimum amount for each Borrowing specified
          in
Section 2.2, (ii) whether any conditions specified in Section 7
          are then satisfied, (iii) whether a Default or an Event of Default has
          occurred
          and is continuing, (iv) the date of such Mandatory Borrowing or (v) any
          reduction in the Total Revolving Credit Commitment after any such Swingline
          Loans were made.  In the event that, in the sole judgment of the
          Swingline Lender, any Mandatory Borrowing cannot for any reason be made
          on the
          date otherwise required above (including as a result of the commencement
          of a
          proceeding under the Bankruptcy Code in respect of the Borrower), each
          Revolving
          Credit Lender hereby agrees that it shall forthwith purchase from the Swingline
          Lender (without recourse or warranty) such participation of the outstanding
          Swingline Loans as shall be necessary to cause each such Lender to share
          in such
          Swingline Loans ratably based upon their respective Revolving Credit Commitment
          Percentages; provided that all principal and interest payable on such
          Swingline Loans shall be for the account of the Swingline Lender until
          the date
          the respective participation is purchased and, to the extent attributable
          to the
          purchased participation, shall be payable to the Lender purchasing same
          from and
          after such date of purchase.

         

        (iii)           Resignation
          of Swingline Lender.  The Swingline Lender may resign as Swingline
          Lender upon 60 days’ prior written notice to the Administrative Agent, the
          Lenders and the Borrower.  If the Swingline Lender shall resign, then
          the Borrower may appoint from among the Lenders a successor Swingline Lender,
          whereupon such successor Swingline Lender shall succeed to the rights,
          powers
          and duties of the replaced or resigning Swingline Lender under this Agreement
          and the otherCredit Documents, and the term “Swingline Lender” shall mean such
          successor or such new Swingline Lender effective upon such
          appointment.  The acceptance of any appointment as a Swingline Lender
          hereunder shall be evidenced by an agreement entered into by such successor,
          in
          a form satisfactory to the Borrower and the Administrative Agent.  If
          the Swingline Lender resigns as Swingline Lender, it shall retain all rights
          of
          the Swingline Lender provided for hereunder with respect to Swingline Loans
          made
          by it and outstanding as of the effective date of such resignation, including
          the right to require the Lenders to make Revolving Credit Loans and fund
          risk
          participations in outstanding Swingline Loans.

         

        (f)           Each
          Lender may at its option make any LIBOR Loan by causing any domestic or
          foreign
          branch or Affiliate of such Lender to make such Loan; provided that
          (A) any exercise of such option shall not affect the obligation of the
          Borrower to repay such Loan and (B) in exercising such option, such Lender
          shall use its reasonable efforts to minimize any increased costs to the
          Borrower
          resulting therefrom (which obligation of the Lender shall not require it
          to
          take, or refrain from taking, actions that it determines would result in
          increased costs for which it will not be compensated hereunder or that
          it
          determines would be otherwise disadvantageous to it and in the event of
          such
          request for costs for which compensation is provided under this Agreement,
          the
          provisions of Section 2.10 shall apply).

          Minimum
          Borrowing Amount for such Type of

          Loans shall be in a minimum amount of at least the Minimum Borrowing Amount
          for
          Swingline Loans and in a multiple of $100,000 in excess thereof (except

        portion,
          if any, of each Borrowing requested to be made on such date in the manner
          provided below; provided that all Swingline Loans shall be made available
          in the full amount thereof by the Swingline Lender no later than 3:30 p.m.
          (New York City time) on the date requested; provided, further,
          that on the Closing Date, such funds may be made available at such earlier
          time
          as may be agreed among the Lenders, the Borrower and the Administrative
          Agent
          for the purpose of consummating the Transactions.

         

        (b)           Each
          Lender shall make available all amounts it is to fund to the Borrower under
          any
          Borrowing for its applicable Commitments in immediately available funds
          to the
          Administrative Agent at the Administrative Agent’s Office in Dollars, and the
          Administrative Agent will (except in the case of Mandatory Borrowings and
          Borrowings of Revolving Credit Loans to reimburse Unpaid Drawings under
          Revolving Letters of Credit) make available to the Borrower, by depositing
          to an
          account designated by the Borrower to the Administrative Agent the aggregate
          of
          the amounts so made available in Dollars.  Unless the Administrative
          Agent shall have been notified by any Lender prior to the date of any such
          Borrowing that such Lender does not intend to make available to the
          Administrative Agent its portion of the Borrowing or Borrowings to be made
          on
          such date, the Administrative Agent may assume that such Lender has made
          such
          amount available to the Administrative Agent on such date of Borrowing,
          and the
          Administrative Agent, in reliance upon such assumption, may (in its sole
          discretion and without any obligation to do so) make available to the Borrower
          a
          corresponding amount.  If such corresponding amount is not in fact
          made available to the Administrative Agent by such Lender and the Administrative
          Agent has made available such amount to the Borrower, the Administrative
          Agent
          shall be entitled to recover such corresponding amount from such
          Lender.  If such Lender does not pay such corresponding amount
          forthwith upon the Administrative Agent’s demand therefor the Administrative
          Agent shall promptly notify the Borrower and the Borrower shall immediately
          pay
          such corresponding amount to the Administrative Agent in Dollars.  The
          Administrative Agent shall also be entitled to recover from such Lender
          or the
          Borrower interest on such corresponding amount in respect of each day from
          the
          date such corresponding amount was made available by the Administrative
          Agent to
          the Borrower to the date such corresponding amount is recovered by the
          Administrative Agent, at a rate per annum equal to (i) if paid by such
          Lender, the Overnight Rate or (ii) if paid by the Borrower, the then-applicable
          rate of interest or fees, calculated in accordance with Section 2.8, for
          the respective Loans.

         

        (c)           Nothing
          in this Section 2.4 shall be deemed to relieve any Lender from its
          obligation to fulfill its commitments hereunder or to prejudice any rights
          that
          the Borrower may have against any Lender as a result of any default by
          such
          Lender hereunder (it being understood, however, that no Lender shall be
          responsible for the failure of any other Lender to fulfill its commitments
          hereunder).

         

        2.5.           Repayment
          of Loans; Evidence of Debt

          then-outstanding Initial Term Loans, (ii) on the Delayed Draw Term Loan
          Maturity
          Date, the then-outstanding Delayed Draw Term Loans, (iii) on the Deposit
          L/C
          Loan Maturity Date, the then-outstanding Deposit L/C Loans, (iv) on the
          relevant
          maturity date for any tranche of Incremental Term Loans, any then outstanding
          Incremental Term Loans of such tranche, (v) on the relevant maturity date
          for
          any tranche of Incremental Deposit L/C Loans, any then outstanding Incremental

          Date,
          all then outstanding Revolving Credit Loans and (vii) on the Swingline

          Borrower shall repay to the Administrative Agent, in Dollars, (i) for the
          benefit of the Lenders of Initial Term Loans, on the last Business Day
          of each
          March, June, September and December commencing December 31, 2007 (each,

        aggregate
          principal amount equal to 0.25% of the aggregate principal amount of all
          Initial
          Term Loans outstanding on the Closing Date (each, an “Initial Term Loan
          Repayment Amount”) (which payments shall be reduced as a result of
          prepayments to Initial Term Loans in accordance with Section 5.2(c)) and
          (ii) for the benefit of the Lenders of Delayed Draw Term Loans, on the
          last
          Business Day of each March, June, September and December commencing with
          the
          first such date to occur following the Delayed Draw Term Loan Commitment
          Termination Date (each, a “Delayed Draw Term Loan Repayment
          Date”), an aggregate principal amount equal to 0.25% of the aggregate
          principal amount of all Delayed Draw Term Loans outstanding on the Delayed
          Draw
          Term Loan Commitment Termination Date (each, a “Delayed Draw Term Loan
          Repayment Amount”) (which payments shall be reduced as a result of
          prepayments to Delayed Draw Term Loans in accordance with Section
          5.2(c)).

         

        (c)           In
          the event any Incremental Term Loans or Incremental Deposit L/C Loans are
          made,
          such Incremental Term Loans or Incremental Deposit L/C Loans, as applicable,
          shall be repaid in amounts and on dates as agreed between the Borrower
          and the
          relevant Lenders of such Incremental Term Loans or Incremental Deposit
          L/C
          Loans, subject to the requirements set forth in Section
          2.14.

         

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

         

        (e)           The
          Administrative Agent shall maintain the Register pursuant to
Section 13.6(b), and a subaccount for each Lender, in which Register
          and subaccounts (taken together) shall be recorded (i) the amount of each
          Loan
          made hereunder, whether such Loan is an Initial Term Loan, a Delayed Draw
          Term
          Loan, an Incremental Term Loan (and the relevant tranche thereof), a Deposit
          L/C
          Loan, an Incremental Deposit L/C Loan (and the relevant tranche thereof),
          a
          Revolving Credit Loan or Swingline Loan, as applicable, the Type of each
          Loan
          made and the Interest Period applicable thereto, (ii) the amount of any
          principal or interest due and payable or to become due and payable from

          amount
          of any sum received by the Administrative Agent hereunder from the Borrower
          and
          each Lender’s share thereof.

          entries made in the Register and accounts and subaccounts maintained pursuant
          to
clauses (d) and (e) of this Section 2.5 shall, to the
          extent permitted by Applicable Law, be prima facie evidence of the existence
          and
          amounts of the obligations of the Borrower therein recorded; provided,
however, that the failure of any Lender or the Administrative
          Agent to
          maintain such account, such Register or such subaccount, as applicable,
          or any
          error therein, shall not in any manner affect the obligation of the Borrower
          to
          repay (with applicable interest) the Loans made to the Borrower by such
          Lender
          in accordance with the terms of this Agreement.

         

        2.6.           Conversions
          and Continuations

         

        .

         

        (a)           Subject
          to the penultimate sentence of this clause 1, (x) the Borrower shall have
          the option on any Business Day to convert all or a portion equal to at
          least the
          Minimum Borrowing Amount of the outstanding principal amount of Initial
          Term
          Loans, Delayed Draw Term Loans, Deposit L/C Loans, Incremental Term Loans,
          Incremental Deposit L/C Loans or Revolving Credit Loans of one Type into
          a
          Borrowing or Borrowings of another Type and (y) the Borrower shall have
          the
          option on any Business Day to continue the outstanding principal amount
          of any
          LIBOR Loans as LIBOR Loans for an additional Interest Period; provided
          that (i) no partial conversion of LIBOR Loans shall reduce the outstanding
          principal amount of LIBOR Loans made pursuant to a single Borrowing to less than
          the Minimum Borrowing Amount, (ii) ABR Loans may not be converted into
          LIBOR
          Loans if a Default or Event

         

        
          
             

          

          
            -79-

            
              

            

          

          
             

          

        

        of
          Default is in existence on the date of the conversion and the Administrative
          Agent has or the Required Lenders have determined in its or their sole
          discretion not to permit such conversion, (iii) LIBOR Loans may not be
          continued as LIBOR Loans for an additional Interest Period if a Default
          or Event
          of Default is in existence on the date of the proposed continuation and
          the
          Administrative Agent has or the Required Lenders have determined in its
          or their
          sole discretion not to permit such continuation, (iv) Borrowings resulting
          from
          conversions pursuant to this Section 2.6 shall be limited in number as
          provided in Section 2.2 and (v) Swingline Loans may not be converted
          to LIBOR Loans.  Each such conversion or continuation shall be
          effected by the Borrower by giving the Administrative Agent at the
          Administrative Agent’s Office prior to 1:00 p.m. (New York City time) at least
          (i) three Business Days’, in the case of a continuation of, or conversion to,
          LIBOR Loans or (ii) one Business Day’s in the case of a conversion into ABR
          Loans, prior written notice (or telephonic notice promptly confirmed in
          writing)
          (each, a “Notice of Conversion or Continuation”) specifying the
          Loans to be so converted or continued, the Type of Loans to be converted
          into or
          continued and, if such Loans are to be converted into, or continued as,
          LIBOR
          Loans, the Interest Period to be initially applicable thereto (if no Interest
          Period is selected, the Borrower shall be deemed to have selected an Interest
          Period of one month’s duration).  The Administrative Agent shall give
          each applicable Lender notice as promptly as practicable of any such proposed
          conversion or continuation affecting any of its Loans.

         

        (b)           If
          any Default or Event of Default is in existence at the time of any proposed
          continuation of any LIBOR Loans and the Administrative Agent has or the
          Required
          Lenders have determined in its or their sole discretion not to permit such
          continuation, such LIBOR Loans shall be automatically converted on the
          last day
          of the current Interest Period into ABR Loans.  If upon the expiration
          of any Interest Period in respect of LIBOR Loans, the Borrower has failed
          to
          elect a new Interest Period to be applicable thereto as provided in
clause (a) above, the Borrower shall be deemed to
          have elected to convert such Borrowing of LIBOR Loans into a Borrowing
          of ABR
          Loans, effective as of the expiration date of such current Interest
          Period.

         

        (c)           Notwithstanding
          anything to the contrary herein, the Borrower may deliver a Notice of Conversion
          or Continuation pursuant to which the Borrower elects to irrevocably continue
          the outstanding principal amount of any Term Loans subject to an interest
          rate
          Hedging Agreement as LIBOR Loans for each Interest Period until the expiration
          of the term of such applicable Hedging Agreement.

         

        2.7.           Pro
          Rata Borrowings

         

        .  Each
          Borrowing of Initial Term Loans under this Agreement shall be made by the
          Lenders pro
          rata on the basis of their then-applicable Initial Term Loan
          Commitments.  Each Borrowing of Delayed Draw Term Loans under this
          Agreement shall be made by the Lenders pro rata
          on
          the basis of their then-applicable Delayed Draw Term Loan
          Commitments.  Each Borrowing of Deposit L/C Loans under this Agreement
          shall be made by the Lenders pro rata
          on
          the basis of their then-applicable Deposit L/C Loan Commitments.  Each
          Borrowing of Revolving Credit Loans under this Agreement shall be made
          by the
          Lenders pro rata on the basis of their then applicable Revolving Credit
          Commitments.  It is understood that (a) no Lender shall be responsible
          for any default by any other Lender in its obligation to make Loans hereunder
          and that each Lender severally but not jointly shall be obligated to make
          the
          Loans provided to be made by it hereunder, regardless of the failure of
          any
          other Lender to fulfill its commitments hereunder and (b) failure by a
          Lender to
          perform any of its obligations under any of the Credit Documents shall
          not
          release any Person from performance of its obligation under any Credit
          Document.

        (a)           The
          unpaid principal amount of each ABR Loan shall bear interest from the date
          of
          the Borrowing thereof until maturity (whether by acceleration or otherwise)
          at a
          rate per annum that shall at all times be the Applicable ABR Margin
plus the ABR, in each case, in effect from time to time.

         

        (b)           The
          unpaid principal amount of each LIBOR Loan shall bear interest from the
          date of
          the Borrowing thereof until maturity thereof (whether by acceleration or
          otherwise) at a rate per annum that shall at all times be the
          Applicable LIBOR Margin plus the relevant LIBOR Rate, in each case in
          effect from time to time.

         

        (c)           The
          unpaid average amount of the Aggregate Posting Advances Outstanding during
          each
          Posting Interest Period shall bear interest from and including the first
          date of
          such period to but excluding the first date of the next succeeding Weekly
          Interest Period at a rate per annum that shall at all times be the relevant
          LIBOR Rate for such Posting Interest Period.

         

        (d)           If
          all or a portion of (i) the principal amount of any Loan or Posting Advance
          or (ii) any interest payable thereon or any other amount hereunder shall
          not be paid when due (whether at the stated maturity, by acceleration or
          otherwise), such overdue amount shall bear interest at a rate per annum
          (the “Default Rate”) that is (x) in the case of overdue
          principal, the rate that would otherwise be applicable thereto plus 2% or
          (y) in the case of any overdue interest or other amounts due hereunder, to
          the extent permitted by Applicable Law, the rate described in
Section 2.8(a) (or, in the case of the Posting Facility, the rate
          described in Section 2.8(c)) plus 2% from the date of such
          non-payment to the date on which such amount is paid in full (after as
          well as
          before judgment).

         

        (e)           Interest
          on each Loan and on each Posting Advance shall accrue from and including
          the
          date of any Borrowing to but excluding the date of any repayment thereof
          and
          shall (including Posting Advances) be payable in Dollars; provided that
          any Loan that is repaid on the same date on which it is made shall bear
          interest
          for one day.  Except as provided below, interest shall be payable (i)
          in respect of each ABR Loan, quarterly in arrears on the tenth Business
          Day
          following the end of each March, June, September and December, (ii) in
          respect
          of each LIBOR Loan, on the last day of each Interest Period applicable
          thereto
          and, in the case of an Interest Period in excess of three months, on each
          date
          occurring at three-month intervals after the first day of such Interest
          Period,

          interest on ABR Loans shall only become due pursuant to this subclause
          (A) if
          the aggregate principal amount of the ABR Loans then outstanding is repaid
          in
          full, (B) at maturity (whether by acceleration or otherwise) and (C) after
          such
          maturity, on demand, and (iv) in respect of each Posting Advance, on each
          Weekly
          Interest Payment Date to the Posting Agent, for the account of the relevant
          Posting Lenders, the amount of interest applicable to the Posting Interest
          Period ending on such Weekly Interest Payment Date as computed pursuant
          to
Section 2.8(c) of this Agreement; provided that, to the extent any
          such interest payment on any Posting Advance is subject to a netting and/or
          settlement agreement, such interest payment shall be applied, paid or otherwise
          netted and/or settled, on behalf of the Borrower, as required
          thereunder.

         

        (f)           All
          computations of interest hereunder shall be made in accordance with
Section 5.5.

         

        (g)           The
          Administrative Agent, upon determining the interest rate for any Borrowing
          of
          LIBOR Loans, shall promptly notify the Borrower and the relevant Lenders
          thereof.  Each such determination shall, absent clearly demonstrable
          error, be final and conclusive and binding on all parties hereto.

         

        (h)           The
          Posting Agent, upon determining the LIBOR Rate for each Posting Interest
          Period,
          shall promptly notify the Borrower and the Posting Calculation Agent of
          such
          determination by

         

        
          
             

          

          
            -81-

            
              

            

          

          
             

          

        

        no
          later than 10:00 a.m. (New York City time) on the relevant Weekly Interest
          Payment Date.  Notice of such amount may be provided by email at the
          address set forth on Schedule 13.2.

         

        (i)           In
          the event that the Administrative Agent or the Borrower determine that
          any
          Section 9.1 Financials previously delivered were incorrect or inaccurate
          and
          such inaccuracy, if corrected, would have led to the application of a higher
          Applicable ABR Margin or Applicable LIBOR Margin for any period (an
“Applicable Period”) than the Applicable ABR Margin or
          Applicable LIBOR Margin applied for such Applicable Period, then (i) the
          Borrower shall as soon as practicable deliver to the Administrative Agent
          the
          correct Section 9.1 Financials for such Applicable Period, (ii) the Applicable
          ABR Margin or Applicable LIBOR Margin, as the case may be, shall be determined
          as if the pricing level for such higher Applicable ABR Margin or Applicable
          LIBOR Margin, as the case may be, were applicable for such Applicable Period,
          and (iii) the Borrower shall within 15 days after delivery of such financial
          statements pay to the Administrative Agent the accrued additional interest
          owing
          as a result of such increased Applicable ABR Margin or Applicable LIBOR
          Margin,
          as the case may be, for such Applicable Period, which payment shall be
          promptly
          applied by the Administrative Agent in accordance with this
          Agreement.  This Section 2.8(i) shall not limit the rights of
          the Administrative Agent and Lenders with respect to Section 2.8(d) and
Section 11.

         

        (j)           Within
          20 Business Days following the end of each March, June, September and December
          (commencing with December 31, 2007), (i) if the Shortfall Amount at the
          end of
          such month is positive, the Administrative Agent shall pay to the Borrower
          an
          amount equal to such Shortfall Amount and (ii) if the Shortfall Amount
          at the
          end of such month is negative, the Administrative Agent shall deliver notice
          to
          the Borrower of such Shortfall Amount and, within 10 Business Days of receipt
          of
          such notice, the Borrower shall pay to the Administrative Agent an amount
          equal
          to such Shortfall Amount (each such payment under clause (i) or (ii), a
          “Shortfall Payment”); provided that in no event shall the
          Borrower be obligated to make Shortfall Payments to the Administrative
          Agent
          that, in the aggregate, exceed the greater of (x) the aggregate amount
          of
          Shortfall Payments made by the Administrative Agent to the Borrower from
          the
          Closing Date through any such date of determination and (y) the Upside
          Amount as
          of the date of such determination (each such payment made pursuant to this
          clause (y) in excess of the amount in clause (x), an “Upside Amount
          Payment”).

         

        2.9.           Interest
          Periods

         

        .  At
          the time the Borrower gives a Notice of Borrowing or Notice of Conversion
          or
          Continuation in respect of the making of, or conversion into or continuation
          as,
          a Borrowing of LIBOR Loans in accordance with Section 2.6(a), the
          Borrower shall give the Administrative Agent written notice (or telephonic
          notice promptly confirmed in writing) of the Interest Period applicable
          to such
          Borrowing, which Interest Period shall, at the option of the Borrower be
          a one,
          two, three or six or (if available to all relevant Lenders participating
          in the
          relevant Credit Facility) a nine or twelve month period or a period of
          less than
          one month; provided that, notwithstanding the foregoing, the initial
          Interest Period beginning on the Closing Date may be for a period of less
          than
          one month if agreed upon by the Borrower and the Administrative
          Agent.

         

        Notwithstanding
          anything to the contrary contained above:

         

        (a)           the
          initial Interest Period for any Borrowing of LIBOR Loans shall commence
          on the
          date of such Borrowing (including the date of any conversion from a Borrowing
          of
          ABR Loans) and each Interest Period occurring thereafter in respect of
          such
          Borrowing shall commence on the day on which the next preceding Interest
          Period
          expires;

         

        (b)           if
          any Interest Period relating to a Borrowing of LIBOR Loans begins on the
          last
          Business Day of a calendar month or begins on a day for which there is
          no
          numerically corresponding day

         

        
          
             

          

          
            -82-

            
              

            

          

          
             

          

        

        in
          the calendar month at the end of such Interest Period, such Interest Period
          shall end on the last Business Day of the calendar month at the end of
          such
          Interest Period;

         

        (c)           if
          any Interest Period would otherwise expire on a day that is not a Business
          Day,
          such Interest Period shall expire on the next succeeding Business Day;
          provided that if any Interest Period in respect of a LIBOR Loan would
          otherwise expire on a day that is not a Business Day but is a day of the
          month
          after which no further Business Day occurs in such month, such Interest
          Period
          shall expire on the next preceding Business Day;

         

        (d)           the
          Borrower shall not be entitled to elect any Interest Period in respect
          of any
          LIBOR Loan if such Interest Period would extend beyond the applicable Maturity
          Date of such Loan; and

         

        (e)           Posting
          Interest Periods shall be governed by Section 14.

         

        2.10.           Increased
          Costs, Illegality, Etc.

         

        

         

        (a)           In
          the event that (x) in the case of clause (i) below, the
          Administrative Agent (or, in the case of the Posting Facility, the Posting
          Agent) or (y) in the case of clauses (ii) and (iii)
          below, any Lender shall have reasonably determined (which determination
          shall,
          absent clearly demonstrable error, be final and conclusive and binding
          upon all
          parties hereto):

         

        (i)       on
          any date for determining the LIBOR Rate for any Interest Period or on the
          date
          for determining the LIBOR Rate for any Posting Interest Period that (x) 
deposits in the principal amounts and currencies of the Loans or Posting
          Advances, as applicable, comprising such LIBOR Borrowing or Posting Advance,
          as
          the case may be, are not generally available in the relevant market or
          (y) by
          reason of any changes arising on or after the Closing Date affecting the
          interbank LIBOR market, adequate and fair means do not exist for ascertaining
          the applicable interest rate on the basis provided for in the definition
          of
          LIBOR Rate; or

         

        (ii)                  at
          any time, that such Lender shall incur increased costs or reductions in
          the
          amounts received or receivable hereunder with respect to any LIBOR Loans
          or with
          respect to any Posting Advances (other than any increase or reduction
          attributable to (i) Taxes indemnifiable under Section 5.4,
          (ii) net income taxes and franchise and excise taxes (imposed in lieu of
          net income taxes) imposed on any Agent or Lender or (iii) Taxes included
          under clauses (c) and (d) of the definition of “Excluded Taxes”)
          because of (x) any change since the date hereof in any Applicable Law (or
          in the
          interpretation or administration thereof and including the introduction
          of any
          new Applicable Law), such as, for example, without limitation, a change
          in
          official reserve requirements, and/or (y) other circumstances affecting
          the
          interbank LIBOR market or the position of such Lender in such market;
          or

         

        (iii)                  at
          any time, that the making or continuance of any LIBOR Loan or the making
          of any
          Posting Advance has become unlawful as a result of compliance by such Lender
          in
          good faith with any Applicable Law (or would conflict with any such Applicable
          Law not having the force of law even though the failure to comply therewith
          would not be unlawful), or has become impracticable as a result of a contingency
          occurring after the date hereof that materially and adversely affects the
          interbank LIBOR market;

         

        then,
          and in any such event, such Lender (or the Administrative Agent (or, in
          the case
          of the Posting Facility, the Posting Agent), in the case of
clause (i) above) shall within a reasonable time thereafter give
          notice (if by telephone, confirmed in writing) to the Borrower and to the
          Administrative Agent (or, in the case of the Posting Facility, the Posting
          Agent) of such determination (which notice the Administrative

        Agent
          (or the Posting Agent, as applicable) shall promptly transmit to each of
          the
          other Lenders).  Thereafter (x) in the case of
clause (i) above, LIBOR Loans or Posting Advances, as applicable,
          shall no longer be available until such time as the Administrative Agent
          (or the
          Posting Agent, as applicable) notifies the Borrower and the Lenders that
          the
          circumstances giving rise to such notice by the Administrative Agent (or
          the
          Posting Agent, as applicable) no longer exist (which notice the Administrative
          Agent (or the Posting Agent, as applicable) agrees to give at such time
          when
          such circumstances no longer exist), and any Notice of Borrowing or Notice
          of
          Conversion given by the Borrower with respect to LIBOR Loans or any notice
          given
          by the Posting Calculation Agent with respect to any Posting Advances,
          that have
          not yet been incurred shall be deemed rescinded by the Borrower or the
          Posting
          Calculation Agent, as applicable, (y) in the case of
clause (ii) above, the Borrower shall pay to such Lender, promptly
          after receipt of written demand therefor such additional amounts (in the
          form of
          an increased rate of or a different method of calculating, interest or
          otherwise, as such Lender in its reasonable discretion shall determine)
          as shall
          be required to compensate such Lender for such increased costs or reductions
          in
          amounts receivable hereunder (it being agreed that a written notice as
          to the
          additional amounts owed to such Lender, showing in reasonable detail the
          basis
          for the calculation thereof, submitted to the Borrower by such Lender shall,
          absent clearly demonstrable error, be final and conclusive and binding
          upon all
          parties hereto) and (z) in the case of subclause (iii) above,
          the Borrower shall take one of the actions specified in
Section 2.10(b) as promptly as possible and, in any event, within
          the time period required by Applicable Law.

         

        (b)           At
          any time that any LIBOR Loan or any Posting Advance is affected by the
          circumstances described in Section 2.10(a)(ii) or (iii), the
          Borrower may (and in the case of a LIBOR Loan or a Posting Advance, as
          the case
          may be, affected pursuant to Section 2.10(a)(iii) shall) either (x) if
          the affected LIBOR Loan or the affected Posting Advance, as the case may
          be, is
          then being made pursuant to a Borrowing, cancel such Borrowing by giving
          the
          Administrative Agent (or the Posting Agent, as applicable) telephonic notice
          (confirmed promptly in writing) thereof on the same date that the Borrower
          was
          notified by a Lender pursuant to Section 2.10(a)(ii) or (iii) or
          (y) if the affected LIBOR Loan or the affected Posting Advance, as the case
          may be, is then outstanding, upon at least three Business Days’ notice to the
          Administrative Agent (or the Posting Agent, as applicable) require the
          affected
          Lender to convert each such LIBOR Loan or such Posting Advance, as the
          case may
          be, into an ABR Loan; provided that if more than one Lender is affected
          at any time, then all affected Lenders must be treated in the same manner
          pursuant to this Section 2.10(b).

         

        (c)           If,
          after the date hereof, any Change in Law relating to capital adequacy of
          any
          Lender or compliance by any Lender or its parent with any Change in Law
          relating
          to capital adequacy occurring after the date hereof, has or would have
          the
          effect of reducing the rate of return on such Lender’s or its parent’s or its
          Affiliate’s capital or assets as a consequence of such Lender’s commitments or
          obligations hereunder to a level below that which such Lender or its parent
          or
          its Affiliate could have achieved but for such Change in Law (taking into
          consideration such Lender’s or its parent’s policies with respect to capital
          adequacy), then from time to time, promptly after demand by such Lender
          (with a
          copy to the Administrative Agent (or with respect to the Posting Facility,
          the
          Posting Agent), the Borrower shall pay to such Lender such additional amount
          or
          amounts as will compensate such Lender or its parent for such reduction,
          it
          being understood and agreed, however, that a Lender shall not be entitled
          to
          such compensation as a result of such Lender’s compliance with, or pursuant to
          any request or directive to comply with, any Applicable Law as in effect
          on the
          date hereof.  Each Lender, upon determining in good faith that any
          additional amounts will be payable pursuant to this Section 2.10(c), will
          give prompt written notice thereof to the Borrower, which notice shall
          set forth
          in reasonable detail the basis of the calculation of such additional amounts,
          although the failure to give any such notice shall not, subject to
Section 2.13, release or diminish the Borrower’s obligations to pay
          additional amounts pursuant to this Section 2.10(c) upon receipt of
          such notice.

        2.11.           Compensation

         

        .  If
          (i) any payment of principal of any LIBOR Loan is made by the Borrower
          to or for
          the account of a Lender other than on the last day of the Interest Period
          for
          such LIBOR Loan as a result of a payment or conversion pursuant to Section
          2.5, 2.6, 2.10, 5.1, 5.2 or 13.7, as a
          result of acceleration of the maturity of the Loans pursuant to Section
          11 or for any other reason, (ii) any Borrowing of LIBOR Loans is not
          made as
          a result of a withdrawn Notice of Borrowing, (iii)  any ABR Loan is
          not converted into a LIBOR Loan as a result of a withdrawn Notice of Conversion
          or Continuation, (iv) any LIBOR Loan is not continued as a LIBOR Loan,
          as the
          case may be, as a result of a withdrawn Notice of Conversion or Continuation
          or
          (v) any prepayment of principal of any LIBOR Loan is not made as a result
          of a
          withdrawn notice of prepayment pursuant to Section 5.1 or
5.2, the Borrower shall, after receipt of a written request
          by such
          Lender (which request shall set forth in reasonable detail the basis for
          requesting such amount), pay to the Administrative Agent for the account
          of such
          Lender any amounts required to compensate such Lender for any additional
          losses,
          costs or expenses that such Lender may reasonably incur as a result of
          such
          payment, failure to convert, failure to continue or failure to prepay,
          including
          any loss, cost or expense (excluding loss of anticipated profits) actually
          incurred by reason of the liquidation or reemployment of deposits or other
          funds
          acquired by any Lender to fund or maintain such LIBOR Loan.  It is
          agreed and understood that the provisions of this Section 2.11 shall not
          apply
          to any Posting Advances.

         

        2.12.           Change
          of Lending Office

         

        .  Each
          Lender agrees that, upon the occurrence of any event giving rise to the
          operation of Section 2.10(a)(ii), 2.10(a)(iii), 2.10(b),
3.5 or 5.4 with respect to such Lender, it
          will, if requested by
          the Borrower use reasonable efforts (subject to overall policy considerations
          of
          such Lender) to designate another lending office for any Loans or any Posting
          Advances affected by such event; provided that such designation is made
          on such terms that such Lender and its lending office suffer no economic,
          legal
          or regulatory disadvantage, with the object of avoiding the consequence
          of the
          event giving rise to the operation of any such Section.  Nothing in
          this Section 2.12 shall affect or postpone any of the obligations of the
          Borrower or the right of any Lender provided in Section 2.10, 3.5
          or 5.4.

         

        2.13.           Notice
          of Certain Costs

         

        .  Notwithstanding
          anything in this Agreement to the contrary, to the extent any notice required
          by
Section 2.10, 2.11, 3.5 or 5.4 is given by any
          Lender more than 180 days after such Lender has knowledge (or should have
          had knowledge) of the occurrence of the event giving rise to the additional
          cost, reduction in amounts, loss, tax or other additional amounts described
          in
          such Sections, such Lender shall not be entitled to compensation under
          Section 2.10, 2.11, 3.5 or 5.4, as the case may
          be, for any such amounts incurred or accruing prior to the 181st day prior
          to
          the giving of such notice to the Borrower.

         

        2.14.           Incremental
          Facilities

         

        .

         

        (a)           The
          Borrower may, at any time or from time to time after the Closing Date,
          by notice
          to the Administrative Agent (whereupon the Administrative Agent shall promptly
          deliver a copy to each of the Lenders), request (i) one or more additional
          tranches of term loans (the “Incremental Term Loans”), (ii) one
          or more additional tranches of deposit l/c loans (the “Incremental
          Deposit L/C Loans”), (iii) one or more increases in the amount of the
          Revolving Credit Commitments (each such increase, an “Incremental
          Revolving Commitment Increase”) or (iv) one or more incremental
          commodity cash collateral posting facilities (each, an “Incremental
          Posting Facility”); provided that (A) both at the time of any
          such request and after giving effect to the effectiveness of any Incremental
          Amendment referred to below, no Default or Event of Default shall exist
          and at
          the time that any such Incremental Term Loan, Incremental Deposit L/C Loan,
          Incremental Revolving Commitment Increase or Incremental Posting Facility
          is
          made or effected (and after giving effect thereto), no Default or Event
          of
          Default shall exist and the conditions in Section 7.1 shall be
          satisfied and (B) the Borrower shall be in compliance with

         

        
          
             

          

          
            -85-

            
              

            

          

          
             

          

        

        the
          covenant set forth in Section 10.9 determined on a Pro Forma Basis as of
          the date of the making of such Incremental Term Loan, Incremental Deposit
          L/C
          Loans, Incremental Revolving Commitment Increase or the entering into such
          Incremental Posting Facility, as the case may be, and as of the last day
          of the
          most recent Test Period, in each case as if such Incremental Term Loans,
          Incremental Deposit L/C Loans, Incremental Revolving Credit Commitment
          Increase
          or Incremental Posting Facility, as applicable, had been outstanding on
          the last
          day of such Test Period for testing compliance therewith.

         

        (b)           Each
          tranche of Incremental Term Loans, each tranche of Incremental Deposit
          L/C Loans
          and each Incremental Revolving Commitment Increase shall be in an aggregate
          principal amount that is not less than $50,000,000 (provided that such
          amount may be less than $50,000,000 if such amount represents all remaining
          availability under the limit set forth in the next
          sentence).  Notwithstanding anything to the contrary herein, the
          aggregate amount of all Incremental Term Loans, Incremental Deposit L/C
          Loans
          and the Incremental Revolving Commitment Increases shall not exceed
          $2,000,000,000.

         

        (c)           The
          Incremental Term Loans (i) shall rank pari passu in right of payment and
          of
          security with the Revolving Credit Loans, the Initial Term Loans, the Delayed
          Draw Term Loans, the Posting Advances and the Deposit L/C Loans, (ii) shall
          not
          mature earlier than the Initial Term Loan Maturity Date, (iii) shall have
          interest rates and amortization schedules determined by the Borrower and
          the
          lenders thereof and (iv) may have terms and conditions different from those
          of
          the Initial Term Loans and the Delayed Draw Term Loans; provided that,
          except with respect to the differences set forth in clauses (ii) and
(iii) above, any differences must be reasonably acceptable to
          the
          Administrative Agent.

         

        (d)           The
          Incremental Deposit L/C Loans (i) shall rank pari passu in right of payment
          and
          of security with the Revolving Credit Loans, the Initial Term Loans, the
          Delayed
          Draw Term Loans, the Posting Advances and the Deposit L/C Loans, (ii) shall
          not
          mature earlier than the Deposit L/C Loan Maturity Date, (iii) shall have
          interest rates and amortization schedules determined by the Borrower and
          the
          lenders thereof and (iv) may have terms and conditions different from those
          of
          the Deposit L/C Loans; provided that, except with respect to the
          differences set forth in clauses (ii) and (iii) above, any
          differences must be reasonably acceptable to the Administrative
          Agent.

         

        (e)           Each
          Incremental Posting Facility shall rank pari passu in right of payment
          and of
          security with the Revolving Credit Loans, the Initial Term Loans, the Delayed
          Draw Term Loans, the Posting Advances and the Deposit L/C Loans.

         

        (f)           Each
          notice from the Borrower pursuant to this Section 2.14 shall set forth
          the requested amount and proposed terms of the relevant Incremental Term
          Loans,
          Incremental Deposit L/C Loans, Incremental Revolving Commitment Increases
          or
          Incremental Posting Facilities.  Incremental Term Loans and
          Incremental Deposit L/C Loans may be made, and Incremental Revolving Commitment
          Increases and Incremental Posting Facilities may be provided, by any existing
          Lender (it being understood that (i) no existing Lender will have an obligation
          to make a portion of any Incremental Term Loan, Incremental Deposit L/C
          Loan or
          any Incremental Posting Facility, (ii) no existing Lender with a Revolving
          Credit Commitment will have any obligation to provide a portion of any
          Incremental Revolving Commitment Increase and (iii) the Borrower shall
          have no
          obligation to offer any existing Lender the opportunity to provide any
          such
          Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving
          Credit Increases or Incremental Posting Facilities) or by any other bank
          or
          other financial institution (any such other bank or other financial institution
          being called an “Additional Lender”); provided that the
          Administrative Agent shall have consented (not to be unreasonably withheld)
          to
          such Lender’s or Additional Lender’s making such Incremental Term Loans,
          Incremental Deposit L/C Loans or providing

         

        
          
             

          

          
            -86-

            
              

            

          

          
             

          

        

        such
          Incremental Revolving Commitment Increases if such consent would be required
          under Section 13.6(b) for an assignment of Loans or Commitments, as
          applicable, to such Lender or Additional Lender.

         

        (g)           Commitments
          in respect of Incremental Term Loans, Incremental Deposit L/C Loans, Incremental
          Revolving Commitment Increases and Incremental Posting Facilities shall
          become
          Commitments (or in the case of an Incremental Revolving Commitment Increase
          to
          be provided by an existing Lender with a Revolving Credit Commitment, an
          increase in such Lender’s applicable Revolving Credit Commitment) under this
          Agreement pursuant to an amendment (an “Incremental Amendment”)
          to this Agreement (which shall be substantially in the form of Exhibit L
          to this Agreement) and, as appropriate, the other Credit Documents, executed
          by
          the Borrower, each Lender agreeing to provide such Commitment, if any,
          each
          Additional Lender, if any, except with respect to any Incremental Posting
          Facility, the Administrative Agent and, with respect to any Incremental
          Posting
          Facility, the relevant posting and calculation agents. The Incremental
          Amendment
          may, subject to Section 2.14(c), (d) or (e) as the case may
          be, without the consent of any other Lenders, effect such amendments to
          this
          Agreement and the other Credit Documents as may be necessary, in the reasonable
          opinion of the Administrative Agent and the Borrower, to effect the provisions
          of this Section. The effectiveness of any Incremental Amendment shall be
          subject
          to the satisfaction on the date hereof (each an “Incremental Facility
          Closing Date”) of the conditions in Section 7.1 and such
          other conditions as the parties thereto shall agree.  The Borrower may
          use the proceeds of the Incremental Term Loans, Incremental Deposit L/C
          Loans,
          Incremental Revolving Commitment Increases and Incremental Posting Facilities
          for any purpose not prohibited by this Agreement.

         

        (h)           No
          Lender shall be obligated to provide any Incremental Term Loans, Incremental
          Deposit L/C Loans, Incremental Revolving Commitment Increases or Incremental
          Posting Facilities, unless it so agrees and the Borrower shall not be obligated
          to offer any existing Lender the opportunity to provide any Incremental
          Term
          Loans, Incremental Deposit L/C Loans, Incremental Revolving Credit Increases
          or
          Incremental Posting Facilities.  Upon each increase in the Revolving
          Credit Commitments pursuant to this Section, each Lender with a Revolving
          Credit
          Commitment immediately prior to such increase will automatically and without
          further act be deemed to have assigned to each Lender providing a portion
          of the
          Incremental Revolving Commitment Increase (each an “Incremental
          Revolving Commitment Increase Lender”) in respect of such increase, and
          each such Incremental Revolving Commitment Increase Lender will automatically
          and without further act be deemed to have assumed, a portion of such Lender’s
          participations hereunder in outstanding Revolving Letters of Credit and
          Swingline Loans such that, after giving effect to each such deemed assignment
          and assumption of participations, the percentage of the aggregate outstanding
          (i) participations hereunder in Revolving Letters of Credit and
          (ii) participations hereunder in Swingline Loans held by each Lender with a
          Revolving Credit Commitment (including each such Incremental Revolving
          Commitment Increase Lender) will equal the percentage of the aggregate
          Revolving
          Credit Commitments of all Lenders represented by such Lender’s Revolving Credit
          Commitment.  If, on the date of such increase, there are any Revolving
          Credit Loans outstanding, such Revolving Credit Loans shall on or prior
          to the
          effectiveness of such Incremental Revolving Commitment Increase be prepaid
          from
          the proceeds of additional Revolving Credit Loans made hereunder (reflecting
          such increase in Revolving Credit Commitments), which prepayment shall
          be
          accompanied by accrued interest on the Revolving Credit Loans being prepaid
          and
          any costs incurred by any Lender in accordance with
Section 2.11.  The Administrative Agent and the Lenders
          hereby agree that the minimum borrowing, pro rata borrowing and pro
          rata payment requirements contained elsewhere in this Agreement shall
          not
          apply to the transactions effected pursuant to the immediately preceding
          sentence.

        (a)           Revolving
          Letters of Credit.  (2)  Subject to and upon the terms
          and conditions herein set forth, at any time and from time to time on and
          after
          the Closing Date and prior to the Revolving L/C Maturity Date, each Revolving
          Letter of Credit Issuer agrees, in reliance upon the agreements of the
          Revolving
          Credit Lenders set forth in this Section 3, to issue upon the request of
          the Borrower and for the direct or indirect benefit of the Borrower and
          the
          Restricted Subsidiaries and for the direct or indirect benefit of the Parent
          and
          its other Subsidiaries (excluding the Oncor Subsidiaries) so long as the
          aggregate Stated Amount of all Letters of Credit issued for the Parent
          and its
          other Subsidiaries’ benefit does not exceed $250,000,000, a letter of credit or
          letters of credit (the “Revolving Letters of Credit” and each,
          a “Revolving Letter of Credit”) in such form and with such
          Issuer Documents as may be approved by the Revolving Letter of Credit Issuer
          in
          its reasonable discretion; provided that the Borrower shall be a
          co-applicant, and jointly and severally liable with respect to each Revolving
          Letter of Credit issued for the account of the Parent and its other
          Subsidiaries, US Holdings or a Restricted Subsidiary.

         

        (ii)           Notwithstanding
          the foregoing, (A) no Revolving Letter of Credit shall be issued the Stated
          Amount of which, when added to the Revolving Letters of Credit Outstanding
          at
          such time, would exceed the Revolving Letter of Credit Commitment then
          in
          effect; (B) no Revolving Letter of Credit shall be issued the Stated Amount
          of which would cause the aggregate amount of the Revolving Credit Exposures
          at
          such time to exceed the Total Revolving Credit Commitment then in effect;
          (C)
          each Revolving Letter of Credit shall have an expiration date occurring
          no later
          than the earlier of (x) one year after the date of issuance thereof, unless
          otherwise agreed upon by the Administrative Agent and the Revolving Letter
          of
          Credit Issuer, or as provided under Section 3.2(b) and (y) the Revolving
          L/C Maturity Date; (D) each Revolving Letter of Credit shall be denominated
          in Dollars; (E) no Revolving Letter of Credit shall be issued if it would
          be illegal under any Applicable Law for the beneficiary of the Revolving
          Letter
          of Credit to have a Revolving Letter of Credit issued in its favor; (F) no
          Revolving Letter of Credit shall be issued after the Revolving Letter of
          Credit
          Issuer  has received a written notice from the Borrower or the
          Administrative Agent or the Required Lenders stating that a Default or
          an Event
          of Default has occurred and is continuing until such time as the Revolving
          Letter of Credit Issuer shall have received a written notice (x) of
          rescission of such notice from the party or parties originally delivering
          such
          notice, (y) of the waiver of such Default or Event of Default in accordance
          with the provisions of Section 13.1 or (z) that such Default or
          Event of Default is no longer continuing; and (G) other than in the case
          of
          Existing Letters of Credit, no Revolving Letter of Credit shall be issued
          by a
          Revolving Letter of Credit Issuer the Stated Amount of which, when added
          to the
          Revolving Letters of Credit Outstandings with respect to such Revolving
          Letter
          of Credit Issuer, would exceed the Specified Revolving Letter of Credit
          Commitment of such Revolving Letter of Credit Issuer then in
          effect.

         

        (b)           Deposit
          Letters of Credit.  (3)  Subject to and upon the terms
          and conditions herein set forth, at any time and from time to time on and
          after
          the Closing Date and prior to the Deposit L/C Maturity Date, the Deposit
          Letter
          of Credit Issuer agrees to issue upon the request of and for the account
          of the
          Borrower and the Restricted Subsidiaries and for the direct or indirect
          benefit
          of the Parent and its other Subsidiaries (excluding the Oncor Subsidiaries)
          so
          long as the aggregate Stated Amount of all Letters of Credit issued for
          the
          Parent and its other Subsidiaries’ (excluding the Oncor Subsidiaries) benefit
          does not exceed $250,000,000, a letter of credit or letters of credit (the
          “Deposit Letters of Credit” and each a “Deposit Letter
          of Credit”) in such form and with such Issuer Documents as may be
          approved by the Deposit Letter of Credit Issuer in its reasonable discretion;
          provided that the Borrower shall be a co-applicant, and be jointly and
          severally liable, with respect to each Deposit Letter of Credit issued
          for the
          account of the Parent and its other Subsidiaries, US Holdings or a Restricted
          Subsidiary.

        (ii)           Notwithstanding
          the foregoing, (A) no Deposit Letter of Credit shall be issued the Stated
          Amount
          of which, when added to the Deposit Letters of Credit Outstanding at such
          time,
          would exceed the Deposit L/C Loan Collateral Account Balance, (B) each
          Deposit
          Letter of Credit shall have an expiration date occurring no later than
          the
          earlier of (x) one year after the date of issuance thereof, unless otherwise
          agreed upon by the Administrative Agent and the Deposit Letter of Credit
          Issuer
          or as provided under Section 3.2(b) and (y) the Deposit L/C Maturity
          Date, (C) each Deposit Letter of Credit shall be denominated in Dollars,
          (D) no
          Deposit Letter of Credit shall be issued if it would be illegal under any
          Applicable Law for the beneficiary of the Deposit Letter of Credit to have
          a
          Deposit Letter of Credit issued in its favor, and (E) no Deposit Letter
          of
          Credit shall be issued after the Deposit Letter of Credit Issuer has received
          a
          written notice from the Borrower or the Administrative Agent or the Required
          Lenders stating that a Default or an Event of Default has occurred and
          is
          continuing until such time as the Deposit Letter of Credit Issuer shall
          have
          received a written notice (x) of rescission of such notice from the party
          or
          parties originally delivering such notice, (y) of the waiver of such Default
          or
          Event of Default in accordance with the provisions of Section 13.1 or (z)
          that such Default or Event of Default is no longer continuing.

         

        3.2.           Letter
          of Credit Requests

         

        .

         

        (a)           Whenever
          the Borrower desires that a Letter of Credit be issued, the Borrower shall
          give
          the Administrative Agent and the applicable Letter of Credit Issuer a Letter
          of
          Credit Request by no later than 1:00 p.m. (New York City time) at least two
          (or such lesser number as may be agreed upon by the Administrative Agent
          and
          such Letter of Credit Issuer) Business Days prior to the proposed date
          of
          issuance.  Each notice shall be executed by the Borrower, shall
          specify whether such Letter of Credit is to be a Revolving Letter of Credit
          or
          Deposit Letter of Credit and shall be in the form of Exhibit G, or
          such other form (including by electronic or fax transmission) as agreed
          between
          the Borrower, the Administrative Agent and the applicable Letter of Credit
          Issuer (each a “Letter of Credit Request”).

         

        (b)           If
          the Borrower so requests in any applicable Letter of Credit Request, any
          Letter
          of Credit Issuer may, in its sole and absolute discretion, agree to issue
          a
          Letter of Credit that has automatic extension provisions (each, an
“Auto-Extension Letter of Credit”); provided that any
          such Auto-Extension Letter of Credit must permit the Letter of Credit Issuer
          to
          prevent any such extension at least once in each twelve-month period (commencing
          with the date of issuance of such Letter of Credit) by giving prior notice
          to
          the beneficiary thereof not later than a day (the “Non-Extension Notice
          Date”) in each such twelve-month period to be agreed upon at the time
          such Letter of Credit is issued.  Unless otherwise directed by a
          Letter of Credit Issuer, the Borrower shall not be required to make a specific
          request to such Letter of Credit Issuer for any such extension.  Once
          an Auto-Extension Letter of Credit has been issued, the Borrower and, in
          the
          case of Revolving Letters of Credit, the Revolving Credit Lenders shall
          be
          deemed to have authorized (but may not require) such Letter of Credit Issuer
          to
          permit the extension of such Letter of Credit at any time to an expiry
          date not
          later than, in the case of any Revolving Letter of Credit, the Revolving
          L/C
          Maturity Date, and in the case of any Deposit Letter of Credit, the Deposit
          L/C
          Maturity Date; provided, however, that such Letter of Credit
          Issuer shall not permit any such extension if (A) such Letter of Credit
          Issuer
          has determined that it would not be permitted, or would have no obligation,
          at
          such time to issue such Letter of Credit in its revised form (as extended)
          under
          the terms hereof (by reason of the provisions of clause (ii) of either
Sections 3.1(a) or (b), as applicable, or otherwise), or (B) it
          has received notice (which may be by telephone or in writing) on or before
          the
          day that is five Business Days before the Non-Extension Notice Date from
          the
          Administrative Agent or the Borrower that one or more of the applicable
          conditions specified in Section 7 are not then satisfied, and in each
          such case directing such Letter of Credit Issuer not to permit such
          extension.

         

        
          
             

          

          
            -89-

            
              

            

          

          
             

          

        

        

         

        (c)           Each
          Letter of Credit Issuer shall, at least once each week, provide the
          Administrative Agent a list of all Letters of Credit (including any Existing
          Letter of Credit) issued by it that are outstanding at such time and specifying
          whether such Letters of Credit are Revolving Letters of Credit or Deposit
          Letters of Credit; provided that upon written request from the
          Administrative Agent, such Letter of Credit Issuer shall thereafter notify
          the
          Administrative Agent in writing on each Business Day of all Letters of
          Credit
          issued on the prior Business Day by such Letter of Credit Issuer and specifying
          whether such Letters of Credit are Revolving Letters of Credit or Deposit
          Letters of Credit.

         

        (d)           The
          making of each Letter of Credit Request shall be deemed to be a representation
          and warranty by the Borrower that the Letter of Credit may be issued in
          accordance with, and will not violate the requirements of, Section
          3.1(a)(ii) or Section 3.1(b)(ii), as applicable.

         

        3.3.           Revolving
          Letter of Credit Participations

         

        .

         

        (a)           Immediately
          upon the issuance by the Revolving Letter of Credit Issuer of any Revolving
          Letter of Credit (and on the Closing Date in respect of Existing Letters
          of
          Credit denoted as “Revolving Letters of Credit” on Schedule 1.1(b)), the
          Revolving Letter of Credit Issuer shall be deemed to have sold and transferred
          to each Revolving Credit Lender (each such Revolving Credit Lender, in
          its
          capacity under this Section 3.3, a “Revolving L/C
          Participant”), and each such Revolving L/C Participant shall be deemed
          irrevocably and unconditionally to have purchased and received from the
          Revolving Letter of Credit Issuer, without recourse or warranty, an undivided
          interest and participation (each a “Revolving L/C
          Participation”), to the extent of such Revolving L/C Participant’s
          Revolving Credit Commitment Percentage, in each Revolving Letter of Credit,
          each
          substitute therefor, each drawing made thereunder and the obligations of
          the
          Borrower under this Agreement with respect thereto, and any security therefor
          or
          guaranty pertaining thereto.

         

        (b)           In
          determining whether to pay under any Revolving Letter of Credit, the Revolving
          Letter of Credit Issuer shall have no obligation relative to the Revolving
          L/C
          Participants other than to confirm that (i) any documents required to be
          delivered under such Revolving Letter of Credit have been delivered, (ii)
          the
          Revolving Letter of Credit Issuer has examined the documents with reasonable
          care and (iii) the documents appear to comply on their face with the
          requirements of such Revolving Letter of Credit.  Any action taken or
          omitted to be taken by the Revolving Letter of Credit Issuer under or in
          connection with any Revolving Letter of Credit issued by it, if taken or
          omitted
          in the absence of gross negligence or willful misconduct, shall not create
          for
          the Revolving Letter of Credit Issuer any resulting liability.

         

        (c)           Whenever
          the Revolving Letter of Credit Issuer receives a payment in respect of
          an unpaid
          reimbursement obligation as to which the Administrative Agent has received
          for
          the account of the Revolving Letter of Credit Issuer any payments from
          the
          Revolving L/C Participants, the Revolving Letter of Credit Issuer shall
          pay to
          the Administrative Agent and the Administrative Agent shall promptly pay
          to each
          Revolving L/C Participant that has paid its Revolving Credit Commitment
          Percentage of such reimbursement obligation, in Dollars and in immediately
          available funds, an amount equal to such Revolving L/C Participant’s share
          (based upon the proportionate aggregate amount originally funded by such
          Revolving L/C Participant to the aggregate amount funded by all Revolving
          L/C
          Participants) of the principal amount so paid in respect of such reimbursement
          obligation and interest thereon accruing after the purchase of the respective
          Revolving L/C Participations at the Overnight Rate.

         

        (d)           The
          obligations of the Revolving L/C Participants to make payments to the
          Administrative Agent for the account of the Revolving Letter of Credit
          Issuer
          with respect to Revolving Letters of Credit shall be irrevocable and not
          subject
          to counterclaim, set-off or other defense or any other

         

        
          
             

          

          
            -90-

            
              

            

          

          
             

          

        

        qualification
          or exception whatsoever and shall be made in accordance with the terms
          and
          conditions of this Agreement under all circumstances, including under any
          of the
          following circumstances:

         

        (i)       any
          lack of validity or enforceability of this Agreement or any of the other
          Credit
          Documents;

         

        (ii)                  the
          existence of any claim, set-off, defense or other right that the Borrower
          may
          have at any time against a beneficiary named in a Revolving Letter of Credit,
          any transferee of any Revolving Letter of Credit (or any Person for whom
          any
          such transferee may be acting), the Administrative Agent, the Revolving
          Letter
          of Credit Issuer, any Lender or other Person, whether in connection with
          this
          Agreement, any Revolving Letter of Credit, the transactions contemplated
          herein
          or any unrelated transactions (including any underlying transaction between
          the
          Borrower and the beneficiary named in any such Revolving Letter of
          Credit);

         

        (iii)                  any
          draft, certificate or any other document presented under any Revolving
          Letter of
          Credit proving to be forged, fraudulent, invalid or insufficient in any
          respect
          or any statement therein being untrue or inaccurate in any respect;

         

        (iv)                  the
          surrender or impairment of any security for the performance or observance
          of any
          of the terms of any of the Credit Documents; or

         

        (v)                  the
          occurrence of any Default or Event of Default;

         

        provided,
          however, that no Revolving L/C Participant shall be obligated to pay to
          the Administrative Agent for the account of the Revolving Letter of Credit
          Issuer its Revolving Credit Commitment Percentage of any unreimbursed amount
          arising from any wrongful payment made by the Revolving Letter of Credit
          Issuer
          under a Revolving Letter of Credit as a result of acts or omissions constituting
          willful misconduct or gross negligence on the part of the Revolving Letter
          of
          Credit Issuer.

         

        3.4.           Agreement
          to Repay Letter of Credit Drawings

         

        .

         

        (a)           The
          Borrower hereby agrees to reimburse the applicable Letter of Credit Issuer,
          by
          making payment in Dollars to the Administrative Agent in immediately available
          funds, for any payment or disbursement made by such Letter of Credit Issuer
          under any Letter of Credit (each such amount so paid until reimbursed,
          an
“Unpaid Drawing”) (i) within two Business Days of the date
          of such payment or disbursement, if such Letter of Credit Issuer provides
          notice
          to the Borrower of such payment or disbursement prior to 10:00 a.m.
          (New York City time) on such next succeeding Business Day from the date of
          such payment or disbursement or (ii) if such notice is received after such
          time,
          on the second Business Day following the date of receipt of such notice
          (such
          required date for reimbursement under clause (i) or (ii), as applicable,
          the
“Reimbursement Date”), with interest on the amount so paid or
          disbursed by such Letter of Credit Issuer, from and including the date
          of such
          payment or disbursement to but excluding the Reimbursement Date, at the
          per
          annum rate for each day equal to the Overnight Rate; provided that,
          notwithstanding anything contained in this Agreement to the contrary,
          (i) in the case of any Unpaid Drawings under any Revolving Letters of
          Credit, (A) unless the Borrower shall have notified the Administrative
          Agent and
          the relevant Letter of Credit Issuer prior to 10:00 a.m. (New York City
          time) on the Reimbursement Date that the Borrower intends to reimburse
          the
          relevant Letter of Credit Issuer for the amount of such drawing with funds
          other
          than the proceeds of Revolving Loans, the Borrower shall be deemed to have
          given
          a Notice of Borrowing requesting that, with respect to Revolving Letters
          of
          Credit, the Lenders with Revolving Credit Commitments make Revolving Credit
          Loans (which shall be ABR Loans) on the Reimbursement Date in the amount
          of such
          Unpaid Drawing and (B) the Administrative Agent shall promptly notify each
          Revolving Credit Lender of such drawing and the amount of its
          Revolving

         

        
          
             

          

          
            -91-

            
              

            

          

          
             

          

        

        Credit
          Loan to be made in respect thereof (without regard to the Minimum Borrowing
          Amount), and each Revolving L/C Participant shall be irrevocably obligated
          to
          make a Revolving Credit Loan to the Borrower in the manner deemed to have
          been
          requested in the amount of its Revolving Credit Commitment Percentage of
          the
          applicable Unpaid Drawing by 2:00 p.m. (New York City time) on such
          Reimbursement Date by making the amount of such Revolving Credit Loan available
          to the Administrative Agent and the Administrative Agent shall use the
          proceeds
          of such Revolving Credit Loans solely for purpose of reimbursing the relevant
          Letter of Credit Issuer for the related Unpaid Drawing or (ii), in the
          case of
          any Unpaid Drawing under any Deposit Letter of Credit, unless the Borrower
          shall
          have notified the Administrative Agent and the relevant Letter of Credit
          Issuer
          prior to 10:00 a.m. (New York City time) on the Reimbursement Date that
          the
          Borrower intends to reimburse the relevant Letter of Credit Issuer for
          the
          amount of such drawing with its own funds, the Collateral Agent shall promptly
          cause the amounts on deposit in the Deposit L/C Loan Collateral Account
          to be
          applied to repay in full the amount of such Unpaid Drawing.

         

        In
          the event that the Borrower fails to Cash Collateralize any Revolving Letter
          of
          Credit that is outstanding on the Revolving Credit Termination Date, the
          full
          amount of the Revolving Letters of Credit Outstanding in respect of such
          Revolving Letter of Credit shall be deemed to be an Unpaid Drawing subject
          to
          the provisions of this Section 3.4 except that the Revolving Letter of
          Credit Issuer shall hold the proceeds received from the Lenders as contemplated
          above as cash collateral for such Revolving Letter of Credit to reimburse
          any
          Drawing under such Revolving Letter of Credit and shall use such proceeds
          first,
          to reimburse itself for any Drawings made in respect of such Revolving
          Letter of
          Credit following the Revolving L/C Maturity Date, second, to the extent
          such
          Revolving Letter of Credit expires or is returned undrawn while any such
          cash
          collateral remains, to the repayment of obligations in respect of any Revolving
          Credit Loans that have not been paid at such time and third, to the Borrower
          or
          as otherwise directed by a court of competent jurisdiction.

         

        (b)           The
          obligations of the Borrower under this Section 3.4 to reimburse the
          Letter of Credit Issuers with respect to Unpaid Drawings (including, in
          each
          case, interest thereon) shall be absolute and unconditional under any and
          all
          circumstances and irrespective of any set-off, counterclaim or defense
          to
          payment that the Borrower or any other Person may have or have had against
          any
          Letter of Credit Issuer, the Administrative Agent or any Lender (including
          in
          its capacity as a Revolving L/C Participant), including any defense based
          upon
          the failure of any drawing under a Letter of Credit (each a
“Drawing”) to conform to the terms of the Letter of Credit or
          any non-application or misapplication by the beneficiary of the proceeds
          of such
          Drawing; provided that the Borrower shall not be obligated to reimburse
          any Letter of Credit Issuer for any wrongful payment made by such Letter
          of
          Credit Issuer under the Letter of Credit issued by it as a result of acts
          or
          omissions constituting willful misconduct or gross negligence on the part
          of
          such Letter of Credit Issuer.

         

        3.5.           Increased
          Costs

         

        .  If
          after the date hereof, the adoption of any Applicable Law, or any change
          therein, or any change in the interpretation or administration thereof
          by any
          Governmental Authority, central bank or comparable agency charged with
          the
          interpretation or administration thereof, or actual compliance by a Letter
          of
          Credit Issuer or any Revolving L/C Participant with any request or directive
          made or adopted after the date hereof (whether or not having the force
          of law),
          by any such authority, central bank or comparable agency shall either (a)
          impose, modify or make applicable any reserve, deposit, capital adequacy
          or
          similar requirement against letters of credit issued by any Letter of Credit
          Issuer, or any Revolving L/C Participant’s Revolving L/C Participation therein,
          or (b) impose on any Letter of Credit Issuer or any Revolving L/C Participant
          any other conditions or liabilities affecting its obligations under this

          reduce
          the amount of any sum received or receivable by such Letter of Credit Issuer
          or
          such Revolving L/C Participant hereunder (other than any such increase
          or
          reduction attributable to (i) taxes indemnifiable under Section 5.4, (ii)
          net income taxes and franchise and excise taxes (imposed in lieu of net

          after
          receipt of written demand to the Borrower by such Letter of Credit Issuer

          such Revolving L/C Participant, as the case may be (a copy of which notice
          shall
          be sent by such Letter of Credit Issuer or such Revolving L/C Participant
          to the

          such Revolving L/C Participant such additional amount or amounts as will
          compensate such Letter of Credit Issuer or such Revolving L/C Participant
          for
          such increased cost or reduction, it being understood and agreed, however,
          that
          any Letter of Credit Issuer or a Revolving L/C Participant shall not be
          entitled
          to such compensation as a result of such Person’s compliance with, or pursuant
          to any request or directive to comply with, any such Applicable Law as

          on the date hereof.  A certificate submitted to the Borrower by the

          Issuer or
          such Revolving L/C Participant to the Administrative Agent), setting forth
          in reasonable detail the basis for the determination of such additional
          amount
          or amounts necessary to compensate such Letter of Credit Issuer or such
          Revolving L/C Participant as aforesaid shall be conclusive and binding

          Borrower absent clearly demonstrable error.

         

        3.6.           New
          or Successor Letter of Credit Issuer

         

        .

         

        (a)           Any
          Letter of Credit Issuer may resign as a Letter of Credit Issuer upon 30
          days’
prior written notice to the Administrative Agent, the Lenders and the
          Borrower.  The Borrower may add Revolving Letter of Credit Issuers
          and/or Deposit Letter of Credit Issuers at any time upon notice to the
          Administrative Agent.  If a Letter of Credit Issuer shall resign or be
          replaced, or if the Borrower shall decide to add a new Letter of Credit
          Issuer
          under this Agreement, then the Borrower may appoint from among the Lenders
          a
          successor issuer of Letters of Credit under the applicable Credit Facility
          or a
          new Letter of Credit Issuer under the applicable Credit Facility, as the
          case
          may be, or, with the consent of the Administrative Agent (such consent
          not to be
          unreasonably withheld), another successor or new issuer of Letters of Credit
          under the applicable Credit Facility, whereupon such successor issuer shall
          succeed to the rights, powers and duties of the replaced or resigning Letter
          of
          Credit Issuer under this Agreement and the other Credit Documents, or such
          new
          issuer of Letters of Credit shall be granted the rights, powers and duties
          of a
          Revolving Letter of Credit Issuer or Deposit Letter of Credit Issuer, as
          applicable, hereunder, and the term “Revolving Letter of Credit Issuer” or
“Deposit Letter of Credit Issuer”, as applicable, shall mean such successor or
          include such new issuer of Letters of Credit under the applicable Credit
          Facility effective upon such appointment.  At the time such
          resignation or replacement shall become effective, the Borrower shall pay
          to the
          resigning or replaced Letter of Credit Issuer all accrued and unpaid fees
          owing
          to such Letter of Credit Issuer pursuant to Section
          4.1(d).  The acceptance of any appointment as a Letter of Credit
          Issuer hereunder whether as a successor issuer or new issuer of Letters
          of
          Credit in accordance with this Agreement, shall be evidenced by an agreement
          entered into by such new or successor issuer of Letters of Credit, in a
          form
          satisfactory to the Borrower and the Administrative Agent and, from and
          after
          the effective date of such agreement, such new or successor issuer of Letters
          of
          Credit shall become a “Revolving Letter of Credit Issuer” or “Deposit Letter of
          Credit Issuer”, as applicable, hereunder.  After the resignation or
          replacement of a Letter of Credit Issuer hereunder, the resigning or replaced
          Letter of Credit Issuer shall remain a party hereto and shall continue
          to have
          all the rights and obligations of a Letter of Credit Issuer under this
          Agreement
          and the other Credit Documents with respect to Letters of Credit issued
          by it
          prior to such resignation or replacement, but shall not be required to
          issue
          additional Letters of Credit.  In connection with any resignation or
          replacement pursuant to this clause (a) (but, in case of any such
          resignation, only to the extent that a successor issuer of Letters of Credit
          shall

        have
          been appointed), either (i) the Borrower, the resigning or replaced Letter
          of
          Credit Issuer and the successor issuer of Letters of Credit shall arrange
          to
          have any outstanding Letters of Credit issued by the resigning or replaced
          Letter of Credit Issuer replaced with Letters of Credit issued by the successor
          issuer of Letters of Credit or (ii) in the case of Revolving Letters of
          Credit,
          the Borrower shall cause the successor issuer of Revolving Letters of Credit,
          if
          such successor issuer is reasonably satisfactory to the replaced or resigning
          Revolving Letter of Credit Issuer, to issue “back-stop” Revolving Letters of
          Credit naming the resigning or replaced Revolving Letter of Credit Issuer
          as
          beneficiary for each outstanding Revolving Letter of Credit issued by the
          resigning or replaced Revolving Letter of Credit Issuer, which new Revolving
          Letters of Credit shall have a face amount equal to the Revolving Letters
          of
          Credit being back-stopped and the sole requirement for drawing on such
          new
          Revolving Letters of Credit shall be a drawing on the corresponding back-stopped
          Revolving Letters of Credit.  After any resigning or replaced Letter
          of Credit Issuer’s resignation or replacement as Letter of Credit Issuer, the
          provisions of this Agreement relating to a Letter of Credit Issuer shall
          inure
          to its benefit as to any actions taken or omitted to be taken by it (A)
          while it
          was a Letter of Credit Issuer under this Agreement or (B) at any time with
          respect to Letters of Credit issued by such Letter of Credit
          Issuer.

         

        (b)           To
          the extent that there are, at the time of any resignation or replacement
          as set
          forth in clause (a) above, any outstanding Letters of Credit, nothing
          herein shall be deemed to impact or impair any rights and obligations of
          any of
          the parties hereto with respect to such outstanding Letters of Credit
          (including, without limitation, any obligations related to the payment
          of Fees
          or the reimbursement or funding of amounts drawn), except that the Borrower,
          the
          resigning or replaced Letter of Credit Issuer and the successor issuer
          of
          Letters of Credit shall have the obligations regarding outstanding Letters
          of
          Credit described in clause (a) above.

         

        3.7.           Role
          of Letter of Credit Issuer

         

        .  Each
          Lender and the Borrower agree that, in paying any Drawing under a Letter
          of
          Credit, the relevant Letter of Credit Issuer shall not have any responsibility
          to obtain any document (other than any sight draft, certificates and documents
          expressly required by the Letter of Credit) or to ascertain or inquire
          as to the
          validity or accuracy of any such document or the authority of the Person
          executing or delivering any such document.  None of the Letter of
          Credit Issuers, the Administrative Agent, any of their respective affiliates
          nor
          any correspondent, participant or assignee of any Letter of Credit Issuer
          shall
          be liable to any Lender for (i) any action taken or omitted in connection
          herewith at the request or with the approval of the Required Lenders;
          (ii) any action taken or omitted in the absence of gross negligence or
          willful misconduct; or (iii) the due execution, effectiveness, validity or
          enforceability of any document or instrument related to any Letter of Credit
          or
          Issuer Document.  The Borrower hereby assumes all risks of the acts or
          omissions of any beneficiary or transferee with respect to its use of any
          Letter
          of Credit; provided that this assumption is not intended to, and shall
          not, preclude the Borrower’s pursuing such rights and remedies as it may have
          against the beneficiary or transferee at law or under any other
          agreement.  None of the Letter of Credit Issuers, the Administrative
          Agent, any of their respective affiliates nor any correspondent, participant
          or
          assignee of any Letter of Credit Issuer shall beliable or responsible for
          any of
          the matters described in Section 3.3(d); provided that anything in
          such Section to the contrary notwithstanding, the Borrower may have a claim
          against a Letter of Credit Issuer, and such Letter of Credit Issuer may
          be
          liable to the Borrower, to the extent, but only to the extent, of any direct,
          as
          opposed to consequential or exemplary, damages suffered by the Borrower
          which
          the Borrower proves were caused by such Letter of Credit Issuer’s willful
          misconduct or gross negligence or such Letter of Credit Issuer’s willful failure
          to pay under any Letter of Credit after the presentation to it by the
          beneficiary of a sight draft and certificate(s) strictly complying with
          the
          terms and conditions of a Letter of Credit.  In furtherance and not in
          limitation of the foregoing, each Letter of Credit Issuer may accept documents
          that appear on their face to be in order, without responsibility for further
          investigation, regardless of any notice or information to the contrary,
          and no
          Letter of Credit Issuer shall be responsible for the validity or sufficiency
          of
          any instrument transferring or assigning or purporting to transfer or assign
          a
          Let

        ter
          of Credit or the rights or benefits thereunder or proceeds thereof, in
          whole or
          in part, which may prove to be invalid or ineffective for any
          reason.

         

        3.8.           Cash
          Collateral

         

        .

         

        (a)           Upon
          the request of the Required Lenders or the Administrative Agent if, as of
          the Revolving L/C Maturity Date, there are any Revolving Letters of Credit
          Outstanding, the Borrower shall immediately Cash Collateralize the then
          Revolving Letters of Credit Outstanding.

         

        (b)           If
          any Event of Default shall occur and be continuing, the Revolving Credit
          Lenders
          with Revolving Letter of Credit Exposure representing greater than 50%
          of the
          total Revolving Letter of Credit Exposure or the Administrative Agent may
          require that the Revolving L/C Obligations be Cash Collateralized.

         

        (c)           For
          purposes of this Section 3.8, Section 5.2(b) and Section
          11, “Cash Collateralize” means to pledge and deposit with
          or deliver to the Administrative Agent, for the benefit of the Revolving
          Letter
          of Credit Issuer and the Revolving Credit Lenders, as collateral for the
          Revolving L/C Obligations, cash or deposit account balances in an amount
          equal
          to 100% of the amount of the Revolving Letters of Credit Outstanding required
          to
          be Cash Collateralized pursuant to documentation in form and substance
          reasonably satisfactory to the Administrative Agent and the Revolving Letter
          of
          Credit Issuer (which documents are hereby consented to by the Revolving
          Credit
          Lenders).  Derivatives of such terms have corresponding
          meanings.  The Borrower hereby grants to the Administrative Agent, for
          the benefit of the Revolving Letter of Credit Issuer and the Revolving
          L/C
          Participants, a security interest in all such cash, deposit accounts and
          all
          balances therein and all proceeds of the documentation in form and substance
          reasonably satisfactory to the Administrative Agent and the Revolving Letters
          of
          Credit Issuer (which documents are hereby consented to by the Revolving
          Credit
          Lenders).  Such cash collateral shall be maintained in blocked,
          interest bearing deposit accounts established by and in the name of the
          Administrative Agent.

         

        3.9.           Deposit
          L/C Loan Collateral Account

         

        .  On
          the Closing Date, the Borrower shall establish the Deposit L/C Loan Collateral
          Account for the purpose of cash collateralizing the Borrower’s obligations to
          the Deposit Letter of Credit Issuer in respect of the Deposit Letters of
          Credit.  On the Closing Date, the proceeds of the Deposit L/C Loans,
          together with other funds (if any) provided by the Borrower, shall be deposited
          into the Deposit L/C Loan Collateral Account such that, and the Borrower
          agrees
          that at all times thereafter, and shall immediately cause additional funds
          to be
          deposited and held in the Deposit L/C Loan Collateral Account from time
          to time
          in order that, the Deposit L/C Loan Collateral Account Balance shall at
          least
          equal the Deposit Letters of Credit Outstanding.  The Borrower hereby
          grants to the Collateral Agent, for the benefit of the Deposit Letter of
          Credit
          Issuer, a security interest in the Deposit L/C Loan Collateral Account
          and all
          cash and balances therein and all proceeds of the foregoing, as security
          for the
          Deposit L/C Obligations (and, in addition, grants a security interest therein,
          for the benefit of the Secured Parties as collateral security for the
          Obligations; provided that amounts on deposit in the Deposit L/C Loan
          Collateral Account shall be applied, first, to repay the Deposit L/C Obligations
          and, then, all other Obligations).  Except as expressly provided
          herein or in any other Credit Document, no Person shall have the right
          to make
          any withdrawal from the Deposit L/C Loan Collateral Account or to exercise
          any
          right or power with respect thereto; provided that at any time the
          Borrower shall fail to reimburse any Deposit Letter of Credit Issuer for
          any
          Unpaid Drawing in accordance with Section 3.4(a), the Borrower hereby
          absolutely, unconditionally and irrevocably agrees that the Collateral
          Agent
          shall be entitled to instruct the depositary bank (the “Depositary
          Bank”) of the Deposit L/C Loan Collateral Account to withdraw therefrom
          and pay to the Administrative Agent for account of such Deposit Letter
          of Credit
          Issuer amounts equal to such Unpaid Drawings.  Amounts in the Deposit
          L/C Loan Collateral Ac

        count
          shall be invested by the Depositary Bank in the manner as instructed by
          the
          Administrative Agent (and agreed to by the Depositary Bank).  To the
          extent amounts are invested in Deposit L/C Permitted Investments, the Borrower
          shall bear the risk of loss of principal with respect to any such
          investments.  To the extent amounts are invested in anything other
          than Deposit L/C Permitted Investments, the Administrative Agent shall
          bear the
          risk of loss of principal with respect to any such investments.  So
          long as no Event of Default shall have occurred and be continuing, upon
          at least
          three Business Days’ prior written notice to the Collateral Agent and the
          Administrative Agent, the Borrower may, at any time and from time to time,
          request release of and payment to the Borrower of (and the Collateral Agent
          hereby agrees to instruct the Depositary Bank to release and pay to the
          Borrower) any amounts on deposit in the Deposit L/C Loan Collateral Account
          in
          excess of the Deposit Letter of Credit Commitment (reduced by the aggregate
          amounts withdrawn by the Deposit Letter of Credit Issuer and not subsequently
          deposited by the Borrower), (provided that the Collateral Agent shall
          have received prior confirmation of the amount of such excess from the
          Administrative Agent).  In addition, the Collateral Agent hereby
          agrees to instruct the Depositary Bank to release and pay to the Borrower
          amounts (if any) remaining on deposit in the Deposit L/C Loan Collateral
          Account
          after the termination or cancellation of all Deposit Letters of Credit
          and the
          repayment in full of all outstanding Deposit L/C Loans and Deposit L/C
          Obligations.

         

        3.10.           Existing
          Letters of Credit

         

        .  Subject
          to the terms and conditions hereof, (a) each Existing Letter of Credit
          that is
          outstanding on the Closing Date, listed on Schedule 1.1(b) and denoted
          thereon as a “Deposit Letter of Credit” shall, effective as of the Closing Date
          and without any further action by the Borrower, be continued as a Deposit
          Letter
          of Credit hereunder and from and after the Closing Date shall be deemed
          a
          Deposit Letter of Credit for all purposes hereof and shall be subject to
          and
          governed by the terms and conditions hereof and (b) each Existing Letter

          the
          Parent or its other Subsidiaries, US Holdings or such Restricted Subsidiaries
          inures to the benefit of the Borrower, and that the Borrower’s business derives

          Credit Loans minus the Fronting Fee on the average daily Stated Amount of
          such Revolving Letter of Credit.  Such Revolving Letter of Credit Fees
          shall be due and payable (x) quarterly in arrears on the tenth Business Day

          following the Closing Date, the Borrower may, at its option, on one or
          more
          occasions repay up to 35% of the aggregate principal amount of the Initial
          Tranche B-3 Term Loans subject to a prepayment premium on the principal
          amount
          of Initial Tranche B-3 Term Loans being prepaid equal to the LIBOR Rate
          for an
          interest period of three months plus the Applicable LIBOR Margin in
          effect on such date, plus accrued and unpaid interest thereon to the date
          of such repayment, with the net cash proceeds of one or more Equity Offerings;
          provided that (i) that at least 50% of the sum of the original aggregate
          principal amount of Initial Tranche B-3 Term Loans remains outstanding
          immediately after the occurrence of each such repayment and (ii) that each
          such
          repayment occurs within 90 days of the date of closing of each such Equity
          Offering.

         

        (c)           In
          the event that, prior to the date which is 3 years following the Closing
          Date,
          there shall occur any amendment, amendment and restatement or other modification
          of this Agreement which reduces the Applicable ABR Margin or the Applicable
          LIBOR Margin with respect to the Initial Tranche B-2 Term Loans or any
          prepayment or refinancing of the Initial Tranche B-2 Term Loans with proceeds
          of
          new term loans having lower applicable margins or applicable yield (after
          giving
          effect to any premiums paid on such new term loans) than the Applicable
          ABR
          Margin or the Applicable LIBOR Margin for the Initial Tranche B-2 Term
          Loans as
          of the Closing Date, each such amendment, amendment and restatement,
          modification, prepayment or refinancing, as the case may be, shall be
          accompanied by a fee or prepayment premium, as applicable, equal to (i)
          3%, if
          such amendment, amendment and restatement, modification, prepayment or
          refinancing, as the case may be, occurs after the Closing Date but prior
          to the
          first anniversary of the Closing Date, (ii) 2%, if such amendment, amendment
          and
          restatement, modification, prepayment or refinancing, as the case may be,
          occurs
          on or after the first anniversary of the Closing Date but prior to the
          second
          anniversary of the Closing Date and (iii) 1%, if such amendment, amendment
          and
          restatement, modification, prepayment or refinancing, as the case may be,
          occurs
          on or after the second anniversary of the Closing Date but prior to the
          third
          anniversary of the Closing Date.  As a condition to effectiveness of
          any assignment pursuant to Section 13.7(b) in respect of any amendment,
          amendment and restatement or modification to this Agreement effective prior
          to
          the third anniversary of the ClosingDate that has the effect of reducing
          the
          Applicable ABR Margin or Applicable LIBOR Margin for the Initial Tranche
          B-2
          Term Loans from the Applicable ABR Margin or Applicable LIBOR Margin in
          effect
          on the Closing Date, the Borrower shall pay to such Non-Consenting Lender
          of
          Initial Tranche B-2 Term Loans a premium equal to the premium that would
          apply
          if such Non-Consenting Lender’s Initial Tranche B-2 Term Loans being assigned
          were being prepaid and subject to the premium set forth in the immediately
          preceding sentence.

        (a)           Term
          Loan Prepayments.  (1) (A)  On each occasion that a
          Prepayment Event occurs, the Borrower shall, within three Business Days
          after
          the occurrence of such Prepayment Event (or, in the case of Deferred Net
          Cash
          Proceeds, within three Business Days after the Deferred Net Cash Proceeds
          Payment Date), prepay, in accordance with clauses (c) and (d)
          below, Term Loans in a principal amount equal to 100% of the Net Cash Proceeds
          from such Prepayment Event.  (B) In the event that any Initial Tranche
          B-3 Term Loans are repaid (the “PE RepaidTranche
          B-3Loans”) prior to the third an

        niversary
          of the Closing Date pursuant to this Section 5.2(a)(i), the Borrower
          shall pay to Term Lenders having such PE Repaid Tranche B-3 Loans, the
          Applicable Premium as of the date of such prepayment.

         

        (ii)           Not
          later than the date that is ninety days after the last day of any fiscal
          year
          (commencing with and including the fiscal year ending on or about December
          31,
          2008), the Borrower shall prepay, in accordance with clauses (c) and
(d) below, Term Loans in a principal amount equal to (x) 50%
          of Excess
          Cash Flow for such fiscal year; provided that (A) the percentage in this
Section 5.2(a)(ii) shall be reduced to 25% if, on the date that such
          prepayment is required to be made, the Consolidated Total Debt to Consolidated
          EBITDA Ratio is less than or equal to 6.00 to 1.0 but greater than 4.75
          to 1.0
          and (B) no prepayment of any Term Loans shall be required under this Section
          5.2(a)(ii) if, on the date that such prepayment is required to be made, the
          Consolidated Total Debt to Consolidated EBITDA Ratio is less than or equal
          to
          4.75 to 1.00, minus (y) the principal amount of Term Loans voluntarily
          prepaid pursuant to Section 5.1 during such fiscal year.

         

        (b)           Repayment
          of Revolving Credit Loans.  If on any date the aggregate amount of
          the Lenders’ Revolving Credit Exposures (collectively, the “Aggregate
          Revolving Credit Outstandings”) for any reason exceeds 100% of the
          Total Revolving Credit Commitment then in effect, the Borrower shall forthwith
          repay on such date the principal amount of any Swingline Loans and, after
          all
          Swingline Loans have been paid in full, the Revolving Credit Loans in an
          amount
          necessary to eliminate such deficiency.  If, after giving effect to
          the prepayment of all outstanding Swingline Loans and Revolving Credit
          Loans,
          the Aggregate Revolving Credit Outstandings exceed the Total Revolving
          Credit
          Commitment then in effect, the Borrower shall Cash Collateralize the Revolving
          L/C Obligations to the extent of such excess.

         

        (c)           Application
          to Repayment Amounts.  Subject to Section 5.2(h), each
          prepayment of Term Loans required by Sections 5.2(a)(i)  and
(ii) shall be allocated pro rata among the Initial Term Loans,
          the Delayed Draw Term Loans and the Incremental Term Loans based upon the
          applicable remaining Repayment Amounts due in respect thereof and be applied
          to
          reduce the scheduled Repayment Amounts in direct order of maturity;
provided that, subject to the pro rata application to Repayment Amounts
          within any Class of Term Loans, the Borrower may allocate such prepayment
          in its
          sole discretion among the Class or Classes of Term Loans as the Borrower
          may
          specify.  Subject to Section 5.2(h), with respect to each such
          prepayment, the Borrower will, not later than the date specified in Section
          5.2(a) for making such prepayment, give the Administrative Agent telephonic
          notice (promptly confirmed in writing and which shall include a calculation
          of
          the amount of such prepayment to be applied to eachClass of Term Loans)
          requesting that the Administrative Agent provide notice of such prepayment
          to
          each Lender of Term Loans.

         

        (d)           Application
          to Term Loans, Deposit L/C Loans and Incremental Deposit L/C
          Loans.  With respect to each prepayment of Term Loans, Deposit L/C
          Loans and Incremental Deposit L/C Loans elected to be made by the Borrower
          pursuant to Section 5.1 or, in the case of the Term Loans only, required
          by Sections 5.2(a)(i) and (ii), the Borrower may designate the
          Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant
          to
          which made; provided that (x) the Borrower pays any amounts, if any,
          required to be paid pursuant to Section 2.11 with respect to prepayments
          of LIBOR Loans made on any date other than the last day of the applicable
          Interest Period and (y) no prepayment made pursuant to Section 5.1 or
Section 5.2(a)(i) and (a)(ii) of Delayed Draw Term Loans shall be
          applied to the Delayed Draw Term Loans of any Defaulting Lender.  In
          the absence of a Rejection Notice or a designation by the Borrower as described
          in the preceding sentence, the Administrative Agent shall, subject to the
          above,
          make such designation in its reasonable discretion with a view, but no
          obligation, to minimize breakage costs owing under Section
          2.11.  Upon any prepayment of Deposit L/C Loans, the Deposit
          Letter of Credit Commitment shall be reduced by an amount equal to such
          prepayment and the

         

        
          
             

          

          
            -101-

            
              

            

          

          
             

          

        

        Borrower
          shall be permitted to withdraw an amount up to the amount of such prepayment
          from the Deposit L/C Loan Collateral Account to complete such prepayment;
          provided that after giving effect to such withdrawal, the Deposit Letters
          of Credit Outstanding at such time would not exceed the Deposit L/C Loan
          Collateral Account Balance.

         

        (e)           Application
          to Revolving Credit Loans.  With respect to each prepayment of
          Revolving Credit Loans elected to be made by the Borrower pursuant to Section
          5.1 or required by Section 5.2(b), the Borrower may designate (i) the
          Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant
          to
          which made and (ii) the Revolving Credit Loans to be prepaid; provided
          that (x) each prepayment of any Loans made pursuant to a Borrowing shall
          be
          applied pro rata among such Loans; and (y) notwithstanding the
          provisions of the preceding clause (x), no prepayment made pursuant to
          Section 5.1 or Section 5.2(b) of Revolving Credit Loans shall be
          applied to the Revolving Credit Loans of any Defaulting Lender.  In
          the absence of a designation by the Borrower as described in the preceding
          sentence, the Administrative Agent shall, subject to the above, make such
          designation in its reasonable discretion with a view, but no obligation,
          to
          minimize breakage costs owing under Section 2.11.

         

        (f)           LIBOR
          Interest Periods.  In lieu of making any payment pursuant to this
Section 5.2 in respect of any LIBOR Loan other than on the last day
          of the Interest Period therefor so long as no Event of Default shall have
          occurred and be continuing, the Borrower at its option may deposit with
          the
          Administrative Agent an amount equal to the amount of the LIBOR Loan to
          be
          prepaid and such LIBOR Loan shall be repaid on the last day of the Interest
          Period therefor in the required amount.  Such deposit shall be held by
          the Administrative Agent in a corporate time deposit account established
          on
          terms reasonably satisfactory to the Administrative Agent, earning interest
          at
          the then customary rate for accounts of such type.  Such deposit shall
          constitute cash collateral for the LIBOR Loans to be so prepaid; provided
          that the Borrower may at any time direct that such deposit be applied to
          make
          the applicable payment required pursuant to this
Section 5.2.

         

        (g)           Minimum
          Amount.  No prepayment shall be required pursuant to
Section 5.2(a)(i) in the case of any Prepayment Event yielding Net
          Cash Proceeds of less than $5,000,000 in the aggregate and (ii) unless and
          until the amount at any time of Net Cash Proceeds from Prepayment Events
          required to be applied at or prior to such time pursuant to such Section
          and not
          yet applied at or prior to such time to prepay Term Loans pursuant to such
          Section exceeds (x) $25,000,000 for a single Prepayment Event or (y)
          $100,000,000 in the aggregate for all Prepayment Events (other than those
          that
          are either under the threshold specified in subclause (i) or over the
          threshold specified in subclause (ii)(x)) in any one fiscal year, at
          which time all such Net Cash Proceeds referred to in this subclause (ii)
          with respect to such fiscal year shall be applied as a prepayment in accordance
          with this Section 5.2.

         

        (h)           Rejection
          Right.  The Borrower shall notify the Administrative Agent in
          writing of any mandatory prepayment of Term Loans required to be made pursuant
          to Section 5.2(a), in each case at least three Business Days prior to the
          date of such prepayment.  Each such notice shall specify the date of
          such prepayment and provide a reasonably detailed calculation of the amount
          of
          such prepayment.  The Administrative Agent will promptly notify each
          Lender holding Term Loans of the contents of the Borrower’s prepayment notice
          and of such Lender’s pro rata share of the prepayment.  Each
          Lender may reject all or a portion of its pro rata share of any such
          prepayment of Term Loans required to be made pursuant to Section 5.2(a)
          (such declined amounts, the “Declined Proceeds”) by providing
          written notice (each, a “Rejection Notice”) to the
          Administrative Agent and the Borrower no later than 5:00 p.m. (New York
          time)
          one Business Day after the date of such Lender’s receipt of notice from the
          Administrative Agent regarding such prepayment.  Each Rejection Notice
          shall specify the principal amount of the mandatory prepayment of Term
          Loans to
          be rejected by such Lender.  If a Lender fails to deliver a Rejection
          Notice to the Administrative Agent within the time frame specified above
          or such
          Rejection Notice fails

         

        
          
             

          

          
            -102-

            
              

            

          

          
             

          

        

        to
          specify the principal amount of the Term Loans to be rejected, any such
          failure
          will be deemed an acceptance of the total amount of such prepayment of
          Term
          Loans.  Any Declined Proceeds remaining thereafter shall be retained
          by the Borrower (“Retained Declined Proceeds”).

         

        (i)           Foreign
          Net Cash Proceeds and Excess Cash Flow.  Notwithstanding any other
          provisions of this Section 5.2, (i) to the extent that any or all of
          the Net Cash Proceeds from a Recovery Prepayment Event (a “Foreign
          Recovery Event”) of, or any Disposition by, a Restricted Foreign
          Subsidiary giving rise to an Asset Sale Prepayment Event (a “Foreign
          Asset Sale”) or any amount included in Excess Cash Flow and
          attributable to Foreign Subsidiaries are prohibited or delayed by applicable
          local law from being repatriated to the United States, such portion of
          the Net
          Cash Proceeds or Excess Cash Flow so affected will not be required to be
          applied
          to repay Term Loans at the times provided in this Section 5.2 but may be
          retained by the applicable Restricted Foreign Subsidiary so long, but only
          so
          long, as the applicable local law will not permit repatriation to the United
          States (the Borrower hereby agreeing to cause the applicable Restricted
          Foreign
          Subsidiary to promptly take all actions required by the applicable local
          law to
          permit such repatriation), and once such repatriation of any of such affected
          Net Cash Proceeds or Excess Cash Flow is permitted under the applicable
          local
          law, such repatriation will be immediately effected and such repatriated
          Net
          Cash Proceeds will be promptly (and in any event not later than two Business
          Days after such repatriation) applied (net of additional taxes payable
          or
          reserved against as a result thereof) to the repayment of the Term Loans
          as
          required pursuant to this Section 5.2 and (ii) to the extent that
          the Borrower has determined in good faith that repatriation of any of or
          all the
          Net Cash Proceeds of any Foreign Recovery Event, any Foreign Asset Sale
          or
          Excess Cash Flow would have a material adverse tax consequence with respect
          to
          such Net Cash Proceeds or Excess Cash Flow, the Net Cash Proceeds or Excess
          Cash
          Flow so affected may be retained by the applicable Restricted Foreign
          Subsidiary; provided that, in the case of this clause (ii), on or
          before the date on which any Net Cash Proceeds or Excess Cash Flow so retained
          would otherwise have been required to be applied to reinvestments or prepayments
          pursuant to Section 5.2(a), (x) the Borrower applies an amount equal
          to such Net Cash Proceeds or Excess Cash Flow to such reinvestments or
          prepayments as if such Net Cash Proceeds or Excess Cash Flow had been received
          by the Borrower rather than such Restricted Foreign Subsidiary, less the
          amount
          of additional taxes that would have been payable or reserved against if
          such Net
          Cash Proceeds or Excess Cash Flow had been repatriated (or, if less, the
          Net
          Cash Proceeds or Excess Cash Flow that would be calculated if received
          by such
          Foreign Subsidiary) or (y) such Net Cash Proceeds or Excess Cash Flow are
          applied to the repayment of Indebtedness of a Restricted Foreign
          Subsidiary.

          and Place of Payment

         

        .

         

        (a)           Except
          as otherwise specifically provided herein, all payments under this Agreement
          shall be made by the Borrower without set-off, counterclaim or deduction
          of any
          kind, to the Administrative Agent for the ratable account of the Lenders
          entitled thereto, the Letter of Credit Issuer or the Swingline Lender entitled
          thereto, as the case may be, not later than 2:00 p.m. (New York City time),
          in each case, on the date when due and shall be made in immediately available
          funds at the Administrative Agent’s Office or at such other office as the
          Administrative Agent shall specify for such purpose by notice to the Borrower,
          it being understood that written or facsimile notice by the Borrower to
          the
          Administrative Agent to make a payment from the funds in the Borrower’s account
          at the Administrative Agent’s Office shall constitute the making of such payment
          to the extent of such funds held in such account.  All repayments or
          prepayments of any Loans (whether of principal, interest or otherwise)
          hereunder
          and all other payments under each Credit Document shall be made in
          Dollars.  The Administrative Agent will thereafter cause to be
          distributed on the same day (if payment was actually received by the
          Administrative Agent prior to 2:00 p.m. (New York City time) or, otherwise,
          on the next Business Day) like funds relating to the payment of principal
          or
          interest or fees ratably to the Lenders entitled thereto.

          payments under this Agreement that are made later than 2:00 p.m. (New York
          City time) shall be deemed to have been made on the next succeeding Business
          Day.  Whenever any payment to be made hereunder shall be stated to be
          due on a day that is not a Business Day, the due date thereof shall be
          extended
          to the next succeeding Business Day and, with respect to payments of principal,
          interest shall be payable during such extension at the applicable rate
          in effect
          immediately prior to such extension.

        (a)           Any
          and all payments made by or on behalf of the Borrower or any Guarantor
          under
          this Agreement or any other Credit Document shall be made free and clear
          of, and
          without deduction or withholding for or on account of, any Indemnified
          Taxes; provided that if the Borrower or any Guarantor or
          the Administrative Agent (or, in the case of the Posting Facility, the
          Posting
          Agent) shall be required by Applicable Law to deduct or withhold any Indemnified
          Taxes from such payments, then (i) the sum payable by the Borrower or any
          Guarantor shall be increased as necessary so that after making all required
          deductions and withholdings (including deductions or withholdings applicable
          to
          additional sums payable under this Section 5.4) the Administrative
          Agent, the Collateral Agent, the Posting Agent or any Lender (which term shall
          include each Letter of Credit Issuer and the Swingline Lender for purposes
          of
Section 5.4 and for the purposes of the definition of Excluded Taxes), as
          the case may be, receives an amount equal to the sum it would have received
          had
          no such deductions or withholdings been made, (ii) the Borrower or such
          Guarantor or the Administrative Agent (or, in the case of the Posting Facility,
          the Posting Agent) shall make such deductions or withholdings and (iii) the
          Borrower or such Guarantor or the Administrative Agent (or, in the case
          of the
          Posting Facility, the Posting Agent) shall timely pay the full amount deducted
          or withheld to the relevant Governmental Authority within the time allowed
          and
          in accordance with Applicable Law.  Whenever any Indemnified Taxes are
          payable by the Borrower or such Guarantor, as promptly as possible thereafter,
          the Borrower or Guarantor shall send to the Administrative Agent (or, in
          the
          case of the Posting Facility, the Posting Agent) for its own account or
          for the
          account of such Lender, as the case may be, a certified copy of an original
          official receipt (or other evidence acceptable to such Lender, acting
          reasonably) received by the Borrower or such Guarantor showing payment
          thereof.

         

        (b)           The
          Borrower shall timely pay and shall indemnify and hold harmless the
          Administrative Agent, the Posting Agent, the Collateral Agent and each
          Lender
          with regard to any Other Taxes (whether or not such Other Taxes were correctly
          or legally imposed or asserted by the relevant Governmental
          Authority).

         

        (c)           The
          Borrower shall indemnify and hold harmless the Administrative Agent, the
          Posting
          Agent, the Collateral Agent and each Lender within fifteen Business Days
          after
          written demand therefor, for the full amount of any Indemnified Taxes imposed
          on
          the Administrative Agent, the Posting Agent, the Collateral Agent or such
          Lender
          as the case may be, on or with respect to any payment by or on account
          of any
          obligation of the Borrower or any Guarantor hereunder or under any other
          Credit
          Document (including Indemnified Taxes imposed or asserted on or attributable
          to
          amounts payable under this Section 5.4) and any reasonable expenses
          arising therefrom or with respect thereto, whether or not such Indemnified
          Taxes
          were correctly or legally imposed or asserted by the relevant Governmental
          Authority.  A certificate setting forth reasonable detail as to the
          amount of such payment or liability delivered to the Borrower by a Lender,
          the
          Administrative Agent, the Posting Agent or the Collateral Agent (as applicable)
          on its own behalf or on behalf of a Lender shall be conclusive absent manifest
          error.

         

        (d)           Any
          Non-U.S. Lender that is entitled to an exemption from or reduction of
          withholding tax under the law of the jurisdiction in which the Borrower
          is
          resident for tax purposes, or under

        any
          treaty to which such jurisdiction is a party, with respect to payments
          hereunder
          or under any other Credit Document shall, to the extent it is legally able
          to do
          so, deliver to the Borrower (with a copy to the Administrative Agent (or,
          in the
          case of the Posting Facility, the Posting Agent)), at the time or times
          prescribed by Applicable Law or reasonably requested by the Borrower or
          the
          Administrative Agent (or, in the case of the Posting Facility, the Posting
          Agent), such properly completed and executed documentation prescribed by
          Applicable Law as will permit such payments to be made without withholding
          or at
          a reduced rate of withholding.  A Lender’s obligation under the prior
          sentence shall apply only if the Borrower or the Administrative Agent has
          made a
          request for such documentation.  In addition, any Lender, if requested
          by the Borrower or the Administrative Agent (or, in the case of the Posting
          Facility, the Posting Agent), shall deliver such other documentation prescribed
          by Applicable Law or reasonably requested by the Borrower or the Administrative
          Agent (or, in the case of the Posting Facility, the Posting Agent) as will
          enable the Borrower or the Administrative Agent (or, in the case of the
          Posting
          Facility, the Posting Agent) to determine whether or not such Lender is
          subject
          to backup withholding or information reporting requirements.

         

        (e)           Each
          Non-U.S. Lender with respect to any Loan or Posting Advance made to the
          Borrower
          shall, to the extent it is legally entitled to do so:

         

        (i)       deliver
          to the Borrower and the Administrative Agent (or, in the case of the Posting
          Facility, the Posting Agent), prior to the date on which the first payment
          to
          the Non-U.S. Lender is due hereunder, two copies of (x) in the case of a
          Non-U.S. Lender claiming exemption from U.S. federal withholding tax under
          Section 871(h) or 881(c) of the Code with respect to payments of “portfolio
          interest”, United States Internal Revenue Service Form W-8BEN (together
          with a certificate substantially in the form of Exhibit Q representing
          that such Non-U.S. Lender is not a bank for purposes of Section 881(c) of
          the Code, is not a 10-percent shareholder (within the meaning of
          Section 871(h)(3)(B) of the Code) of the Borrower, any interest payment
          received by such non-U.S. Lender under this Agreement or any other Credit
          Document is not effectively connected with the conduct of a trade or business
          in
          the United States and is not a controlled foreign corporation related to
          the
          Borrower (within the meaning of Section 864(d)(4) of the Code)), (y)
          Internal Revenue Service Form W-8BEN or Form W-8ECI, in each case properly
          completed and duly executed by such Non-U.S. Lender claiming complete exemption
          from, or reduced rate of, U.S. Federal withholding tax on payments by the
          Borrower under this Agreement or (z) if a Non-U.S. Lender does not act or
          ceases to act for its own account with respect to any portion of anysums
          paid or
          payable to such Lender under any of the Credit Documents (for example,
          in the
          case of a typical participation or where Non-U.S. Lender is a pass through
          entity) Internal Revenue Service Form W-8IMY and all necessary attachments
          (including the forms described in clauses (x) and (y) above, as
          required); and

         

        (ii)                  deliver
          to the Borrower and the Administrative Agent (or, in the case of the Posting
          Facility, the Posting Agent) two further copies of any such form or
          certification (or any applicable successor form) on or before the date
          that any
          such form or certification expires or becomes obsolete and after the occurrence
          of any event requiring a change in the most recent form previously delivered
          by
          it to the Borrower.

         

        If
          in any such case any Change in Law has occurred prior to the date on which
          any
          such delivery would otherwise be required that renders any such form
          inapplicable or would prevent such Non-U.S. Lender from duly completing
          and
          delivering any such form with respect to it, such Non-U.S. Lender shall
          promptly
          so advise the Borrower and the Administrative Agent (or, in the case of
          the
          Posting Facility, the Posting Agent).

        (f)           If
          any Lender, the Administrative Agent, the Posting Agent or the Collateral
          Agent,
          as applicable, determines, in its sole discretion, that it had received
          and
          retained a refund of an Indemnified Tax (including an Other Tax) for which
          a
          payment has been made by the Borrower pursuant to this Agreement, which
          refund
          in the good faith judgment of such Lender, the Administrative Agent, the
          Posting
          Agent or the Collateral Agent, as the case may be, is attributable to such
          payment made by the Borrower, then the Lender, the Administrative Agent,
          the
          Posting Agent or the Collateral Agent, as the case may be, shall reimburse
          the
          Borrower for such amount (net of all out-of-pocket expenses of such Lender,
          the
          Administrative Agent, the Posting Agent or the Collateral Agent, as the
          case may
          be, and without interest other than any interest received thereon from
          the
          relevant Governmental Authority with respect to such refund) as the Lender,
          Administrative Agent, the Posting Agent or the Collateral Agent, as the
          case may
          be, determines in its sole discretion to be the proportion of the refund
          as will
          leave it, after such reimbursement, in no better or worse position (taking
          into
          account expenses or any taxes imposed on the refund) than it would have
          been in
          if the payment had not been required; provided that the Borrower, upon
          the request of the Lender, the Administrative Agent, the Posting Agent
          or the
          Collateral Agent, agrees to repay the amount paid over to the Borrower
          (plus any penalties, interest or other charges imposed by the relevant
          Governmental Authority) to the Lender, the Administrative Agent, the Posting
          Agent or the Collateral Agent in the event the Lender, the Administrative
          Agent,
          the Posting Agent or the Collateral Agent is required to repay such refund
          to
          such Governmental Authority.  A Lender, the Administrative Agent, the
          Posting Agent or the Collateral Agent shall claim any refund that it determines
          is available to it, unless it concludes in its sole discretion that it
          would be
          adversely affected by making such a claim.  Neither the Lender, the
          Administrative Agent, the Posting Agent nor the Collateral Agent shall
          be
          obliged to disclose any information regarding its tax affairs or computations
          to
          any Credit Party in connection with this clause (f) or any other
          provision of this Section 5.4.

         

        (g)           If
          the Borrower determines that a reasonable basis exists for contesting a
          Tax,
          each Lender or Agent, as the case may be, shall use reasonable efforts
          to
          cooperate with the Borrower as the Borrower may reasonably request in
          challenging such Tax.  Subject to the provisions of Section
          2.12, each Lender and Agent agrees to use reasonable efforts to cooperate
          with the Borrower as the Borrower may reasonably request to minimize any
          amount
          payable by the Borrower or any Guarantor pursuant to this Section
          5.4.  The Borrower shall indemnify and hold each Lender and Agent
          harmless against any out-of-pocket expenses incurred by such Person in
          connection with any request made by the Borrower pursuant to this Section
          5.4(g).  Nothing in this Section 5.4(g) shall obligate any
          Lender or Agent to take any action that such Person, in its sole judgment,
          determines may result in a material detriment to such Person.

         

        (h)           Each
          Lender and Agent with respect to any Loan or Posting Advance made to the
          Borrower that is a United States person under Section 7701(a)(30) of the
          Code
          (each, a “U.S. Lender”) shall deliver to the Borrower and the
          Administrative Agent (or, in the case of the Posting Facility, the Posting
          Agent) two United States Internal Revenue Service Forms W-9 (or substitute
          or
          successor form), properly completed and duly executed, certifying that
          such
          Lender or Agent is exempt from United States backup withholding (i) on
          or prior
          to the Closing Date (or on or prior to the date it becomes a party to this
          Agreement), (ii) on or before the date that such form expires or becomes
          obsolete, (iii) after the occurrence of a change in the Agent’s or Lender’s
          circumstances requiring a change in the most recent form previously delivered
          by
          it to the Borrower and the Administrative Agent (or, in the case of the
          Posting
          Facility, the Posting Agent) and (iv) from time to time thereafter if reasonably
          requested by the Borrower or the Administrative Agent (or, in the case
          of the
          Posting Facility, the Posting Agent).

         

        (i)           The
          agreements in this Section 5.4 shall survive the termination of this
          Agreement and the payment of the Loans, Posting Advances and all other
          amounts
          payable hereunder.

        (a)           Except
          as provided in the next succeeding sentence, interest on LIBOR Loans, Posting
          Advances and ABR Loans shall be calculated on the basis of a 360-day year
          for
          the actual days elapsed.  Interest on ABR Loans in respect of which
          the rate of interest is calculated on the basis of the Administrative Agent’s
          prime rate and interest on overdue interest shall be calculated on the
          basis of
          a 365- (or 366-, as the case may be) day year for the actual days
          elapsed.

         

        (b)           Fees
          (other than the Maintenance Fee) and the average daily Stated Amount of
          Letters
          of Credit shall be calculated on the basis of a 360-day year for the actual
          days
          elapsed.

         

        (c)           The
          Maintenance Fee shall be calculated by the Posting Calculation Agent in
          the
          manner set forth in the Posting Facility Fee Letter.

         

        (d)           Whenever
          the Posting Calculation Agent makes a determination or calculation under
          this
          Agreement or in respect of the transactions contemplated hereby, the Posting
          Calculation Agent shall make such determination or calculation (i) in good
          faith, (ii) in a commercially reasonable manner, (iii) with respect to
          calculations or determinations involving transaction valuations, consistent
          with
          its practices and procedures for valuing similar transactions and (iv)
          in
          consultation with the Borrower.  The Borrower may, acting in good
          faith, dispute a calculation or determination by the Posting Calculation
          Agent
          which it believes is inaccurate (provided that the Borrower shall make
          any determination or calculation relating to such dispute in a commercially
          reasonable manner).  In the event of such a dispute, the Borrower and
          the Posting Calculation Agent shall first endeavor to resolve such
          dispute.  If the Borrower and the Posting Calculation Agent are unable
          to resolve such dispute within five Business Days, the Borrower and Posting
          Calculation Agent shall mutually select a dealer (with respect to commodity
          related calculations) or a financial institution (with respect to financial
          calculations) that customarily acts as a calculation agent for similar
          transactions to act as Posting Calculation Agent with respect to the issue
          in
          dispute.  If the Borrower and the Posting Calculation Agent cannot
          agree on a dealer or financial institution within one Business Day, then
          each
          shall appoint a dealer or financial institution and the appointed dealers
          or
          financial institutions shall together appoint a third dealer or financial
          institution as Posting Calculation Agent for making the relevant determination,
          and the decision of such Person shall be final and binding upon the
          parties.  The dealers or financial institutions selected by a party
          shall not be parties to this Agreement or Affiliates of a party to this
          Agreement.  It is understood and agreed that, for the avoidance of
          doubt, the Disclaimer for Mark-to-Market Calculation (set forth in
Exhibit O hereto) does not limit the Borrower’s rights under this
Section 5.5(d).

          of this Agreement, the Borrower shall not be obligated to pay any interest
          or
          other amounts under or in connection with this Agreement or otherwise in
          respect
          of the Obligations in excess of the amount or rate permitted under or consistent
          with any applicable law, rule or regulation.

         

        (b)           Payment
          at Highest Lawful Rate.  If the Borrower is not obliged to make a
          payment that it would otherwise be required to make, as a result of Section
          5.6(a), the Borrower shall make such payment to the maximum extent permitted
          by or consistent with applicable laws, rules and regulations.

         

        (c)           Adjustment
          if Any Payment Exceeds Lawful Rate.  If any provision of this
          Agreement or any of the other Credit Documents would obligate the Borrower
          to
          make any payment of interest or other amount payable to any Lender in an
          amount
          or calculated at a rate that would be prohib

        ited
          by any Applicable Law, then notwithstanding such provision, such amount
          or rate
          shall be deemed to have been adjusted with retroactive effect to the maximum
          amount or rate of interest, as the case may be, as would not be so prohibited
          by
          Applicable Law, such adjustment to be effected, to the extent necessary,
          by
          reducing the amount or rate of interest required to be paid by the Borrower
          to
          the affected Lender under Section 2.8.

         

        (d)           Spreading.  In
          determining whether the interest hereunder is in excess of the amount or
          rate
          permitted under or consistent with any Applicable Law, the total amount
          of
          interest shall be spread throughout the entire term of this Agreement until
          its
          payment in full.

         

        (e)           Notwithstanding
          the foregoing, and after giving effect to all adjustments contemplated
          thereby,
          if any Lender shall have received from the Borrower an amount in excess
          of the
          maximum permitted by any Applicable Law, then the Borrower shall be entitled,
          by
          notice in writing to the Administrative Agent to obtain reimbursement from
          that
          Lender in an amount equal to such excess, and pending such reimbursement,
          such
          amount shall be deemed to be an amount payable by that Lender to the
          Borrower.

          case of
          Collateral consisting of mining properties) after the Closing Date or such

          discretion.

          Adverse Effect and (c) is in compliance with all Applicable Laws, except
          to the
          extent that the failure to be in compliance could not reasonably be expected

          of the written factual information and written data (taken as a whole)
          heretofore or contemporaneously furnished by or on behalf of US Holdings,
          the
          Borrower, any of the Subsidiaries of the Borrower or any of their respective

          untrue
          statement of any material fact or omitted to state any material fact necessary

          was furnished, it being understood and agreed that for purposes of this

          projections (including financial estimates, forecasts and other forward-looking
          information) contained in the information and data referred to in Section
          8.8(a) were prepared in good faith based upon estimates and assumptions
          believed by such Persons to be reasonable at the time made, it being recognized
          by the Agents and Lenders that such projections as to future events are
          not to
          be viewed as facts and that actual results during the period or periods
          covered
          by any such projections may differ from the projected results and such

          of operations for the respective periods covered thereby subject, in the
          case of

          Forma Balance Sheet, the “Pro Forma Financial Statements”),
          copies of which have heretofore been furnished to the Administrative Agent,
          have
          been prepared based on the historical financial statements of US Holdings
          and
          have been prepared in good faith, based on assumptions believed by US Holdings
          to be reasonable as of the date of delivery thereof, and, subject to the
          qualifications and limitations contained in the notes attached thereto,
          present
          fairly in all material respects on a Pro Forma Basis the estimated financial
          position of US Holdings and its consolidated Subsidiaries as at June 30,
          2007
          and their estimated results of operations for the period covered
          thereby.  The financial statements referred to in this
Section 8.9 have been prepared in accordance with GAAP consistently
          applied except to the extent provided in the notes to said financial
          statements.  There has been no Material Adverse Effect since the
          Closing Date.

          Matters

          returns,

          other than those (i) not yet delinquent or (ii) contested in good
          faith as to which adequate reserves have been provided to the extent required
          by

        with
          GAAP, (b) each of US Holdings, the Borrower and each of the Restricted
          Subsidiaries has provided adequate reserves in accordance with GAAP for
          the
          payment of, all federal, state, provincial and foreign Taxes not yet due
          and
          payable and (c) each of US Holdings, the Borrower and each of the Restricted
          Subsidiaries has satisfied all of its Tax withholding obligations.

          exist)
          nor has the Borrower or any ERISA Affiliate been notified in writing that

          breach
          of any of the representations, warranties or agreements in this Section
          8.11(a) would not result, individually or in the aggregate, in an amount of
          liability that would be reasonably likely to have a Material Adverse
          Effect.  No Plan has an Unfunded Current Liability that would,
          individually or when taken together with any other liabilities referenced
          in
          this Section 8.11(a), be reasonably likely to have a Material Adverse
          Effect.  With respect to Plans that are Multiemployer Plans, the
          representations and warranties in this Section 8.11(a), other than any
          made with respect to (i) liability under Section 4201 or 4204 of ERISA or
          (ii) liability for termination or reorganization of such Multiemployer
          Plans

          Law, except for any failure to so comply, establish, administer or operate
          the
          Foreign Plans as would not reasonably be expected to have a Material Adverse
          Effect.  All contributions or other payments which are due with
          respect to each Foreign Plan have been made in full and there are no funding
          deficiencies thereunder, except to the extent any such events would not,
          individually or in the aggregate, reasonably be expected to have a Material
          Adverse Effect.

          Parent’s or any direct or indirect parent thereof), as applicable, Form 10-K or
          10-Q, as applicable, filed with the SEC; provided that, with respect to
          each of subclauses (A) and (B) of this paragraph, to the extent
          such information relates to US Holdings, the Parent or a parent of the
          Parent,
          such information is accompanied by consolidating or other information that
          explains in reasonable detail the differences between the information relating
          to US Holdings, the Parent or such parent, on the one hand, and the information
          relating to the Borrower and the Restricted Subsidiaries on a standalone
          basis,
          on the other hand.

         

        
          
             

          

          
            -119-

            
              

            

          

          
             

          

        

        

         

        9.2.           Books,
          Records and Inspections

         

        .  The
          Borrower will, and will cause each Restricted Subsidiary to, permit officers
          and
          designated representatives of the Administrative Agent or the Required
          Lenders
          (as accompanied by the Administrative Agent) to visit and inspect any of
          the
          properties or assets of the Borrower or such Restricted Subsidiary in
          whomsoever’s possession to the extent that it is within such party’s control to
          permit such inspection (and shall use commercially reasonable efforts to
          cause
          such inspection to be permitted to the extent that it is not within such
          party’s
          control to permit such inspection), and to examine the books and records
          of the
          Borrower and any such Restricted Subsidiary and discuss the affairs, finances
          and accounts of the Borrower and of any such Restricted Subsidiary with,
          and be
          advised as to the same by, its and their officers and independent accountants,
          all at such reasonable times and intervals and to such reasonable extent
          as the
          Administrative Agent or Required Lenders may desire (and subject, in the
          case of
          any such meetings or advice from such independent accountants, to such
          accountants’ customary policies and procedures); provided that, excluding
          any such visits and inspections during the continuation of an Event of
          Default
          (a) only the Administrative Agent, whether on its own or in conjunction
          with the
          Required Lenders, may exercise rights of the Administrative Agent and the
          Lenders under this Section 9.2, (b) the Administrative Agent shall
          not exercise such rights more than two times in any calendar year and (c)
          only
          one such visit shall be at the Borrower’s expense; providedfurther
          that when an Event of Default exists, the Administrative Agent (or any
          of its
          representatives or independent contractors) or any representative of any
          Lender
          may do any of the foregoing at the expense of the Borrower at any time
          during
          normal business hours and upon reasonable advance notice.  The
          Administrative Agent and the Required Lenders shall give the Borrower the
          opportunity to participate in any discussions with the Borrower’s independent
          public accountants.

         

        9.3.           Maintenance
          of Insurance

         

        .  The
          Borrower will, and will cause each Material Subsidiary that is a Restricted
          Subsidiary to, at all times maintain in full force and effect, pursuant
          to
          self-insurance arrangements or with insurance companies that the Borrower
          believes (in the good faith judgment of the management of the Borrower,
          as
          applicable) are financially sound and responsible at the time the relevant
          coverage is placed or renewed, insurance in at least such amounts (after
          giving
          effect to any self-insurance which the Borrower believes (in the good faith
          judgment of management of the Borrower, as applicable) is reasonable and
          prudent
          in light of the size and nature of its business) and against at least such
          risks
          (and with such risk retentions) as the Borrower believes (in the good faith
          judgment of management of the Borrower, as applicable) is reasonable and
          prudent
          in light of the size and nature of its business; and will furnish to the
          Administrative Agent, upon written reasonable request from the Administrative
          Agent, information presented in reasonable detail as to the insurance so
          carried.  With respect to each Mortgaged Property, obtain flood
          insurance in such total amount as the Administrative Agent may from time
          to time
          require, if at any time the area in which any improvements located on any
          Mortgaged Property is designated a “flood hazard area” in any Flood Insurance
          Rate Map published by the Federal Emergency Management Agency (or any successor
          agency), and otherwise comply with the National Flood Insurance Program
          as set
          forth in the Flood Disaster Protection Act of 1973, as amended from time
          to
          time.

          of Taxes

         

        .  The
          Borrower will pay and discharge, and will cause each of the Restricted
          Subsidiaries to pay and discharge, all Taxes, assessments and governmental
          charges or levies imposed upon it or upon its income or profits, or upon
          any
          properties belonging to it, prior to the date on which penalties attach
          thereto,
          and all lawful claims in respect of any Taxes imposed, assessed or levied
          that,
          if unpaid, could reasonably be expected to become a material Lien upon
          any
          properties of the Borrower or any Restricted Subsidiary of the Borrower;
          provided that neither the Borrower nor any such Restricted Subsidiary
          shall be required to pay any such tax, assessment, charge, levy or claim
          that is
          being contested in good faith and by proper proceedings if it has maintained
          adequate reserves (in the good faith judgment of management of the Borrower)
          with respect thereto in accordance with GAAP or the failure to pay could
          not
          reasonably be expected to result in a Material Adverse Effect.

        9.5.           Consolidated
          Corporate Franchises

         

        .  The
          Borrower will do, and will cause each Material Subsidiary that is a Restricted
          Subsidiary to do, or cause to be done, all things necessary to preserve
          and keep
          in full force and effect its existence, corporate rights and authority,
          except
          to the extent that the failure to do so could not reasonably be expected
          to have
          a Material Adverse Effect; provided, however, that the Borrower
          and the Restricted Subsidiaries may consummate any transaction permitted
          under
Section 10.3, 10.4 or 10.5.

         

        9.6.           Compliance
          with Statutes, Regulations, Etc.

         

          The
          Borrower will, and will cause each Restricted Subsidiary to, comply with
          all
          Applicable Laws applicable to it or its property, including all governmental
          approvals or authorizations required to conduct its business, and to maintain
          all such governmental approvals or authorizations in full force and effect,
          in
          each case except where the failure to do so could not reasonably be expected
          to
          have a Material Adverse Effect.

          aggregate
          (including in the aggregate such events previously disclosed or exempt
          from
          disclosure hereunder, to the extent the liability therefor remains outstanding),
          would be reasonably likely to have a Material Adverse Effect, the Borrower
          will
          deliver to the Administrative Agent a certificate of an Authorized Officer
          or
          any other senior officer of the Borrower setting forth details as to such
          occurrence and the action, if any, that the Borrower or such ERISA Affiliate
          is

        customary
          for the type of assets covered by such Mortgage may be delivered within
          a
          commercially reasonable period of time after the delivery of a Mortgage

          are not reasonably available at the time the Mortgage is delivered.

         

        (d)           With
          respect to any Post-Closing Mortgaged Property, within 120 days (or 180
          days in
          the case of Collateral consisting of mining properties), unless extended
          by the
          Collateral Agent in its sole discretion, the Borrower will deliver, or
          cause to
          be delivered, to the Collateral Agent (i) a Mortgage with respect to each
          Post-Closing Mortgaged Property, executed by a duly authorized officer
          of each
          obligor party thereto, (ii) title insurance of the type described in
Section 6.2(f)(iii) with respect to each such Mortgaged Property and
          (iii) for each Post-Closing Mortgaged Property consisting of a nuclear or
          coal-fired power plant, a Survey; provided that, notwithstanding the foregoing,
          with respect to the oil, gas and other mineral interests described in item
          4
          under part B of Schedule 1.1(c), the Post-Closing Mortgages will describe
          the mortgaged mineral interests in the manner customary for the mortgaging
          of
          similar mineral interests in similar transactions and there will be no
          title
          insurance or Surveys in connection with such Post-Closing Mortgaged Properties.
          Within 180 days after the granting of each Mortgage with respect to a Closing
          Date Mortgaged Property, the Borrower shall deliver to the Collateral Agent
          a
          Survey with respect to such Closing Date Mortgaged Property constituting
          a
          nuclear or coal fired power generation station.  The Borrower, within
          30 days of the Closing Date, will deliver, or cause to be delivered, (i)
          to the
          extent not delivered pursuant to Section 6.2(f)(v), a completed Federal
          Emergency Management Agency Standard Flood Determination with respect to
          each
          Closing Date Mortgaged Property, in each case in form and substance reasonably
          satisfactory to the Collateral Agent, (ii) evidence of flood insurance
          with
          respect to each Closing Date Mortgaged Property, to the extent and in amounts
          required by  Applicable Laws, in each case in form and substance
          reasonably satisfactory to the Collateral Agent and (iii) revised insurance
          certificates of the type required to be delivered pursuant to Section 6.15
          to
          reflect that such insurance covers all Mortgaged Property and designating
          the
          amount of insurance applicable to each such Mortgaged Property, in each
          case in
          form and substance reasonably acceptable to the Collateral Agent.

         

        (e)           Notwithstanding
          anything herein to the contrary, if the Collateral Agent determines in
          its
          reasonable judgment (confirmed in writing to the Borrower and the Administrative
          Agent) that the cost or other consequences (including adverse tax and accounting
          consequences) of creating or perfecting any Lien on any property is excessive
          in
          relation to the benefits afforded to the Secured Party thereby, then such
          property may be excluded from the Collateral for all purposes of the Credit
          Documents.

          Agent (i) a title insurance bring down and endorsements to the title insurance
          policy insuring the Mortgaged Property upon which such Project was constructed
          amending such title insurance policy to update the policy to a then current
          date
          and reflect that such policy shall be free and clear of all mechanics,
          material-men or other similar liens, except to the extent the same constitute
          Liens expressly permitted pursuant to Section 10.2, (ii) all lien waivers
          from the contractors and subcontractors relating to such Project as shall
          be
          required to be delivered pursuant to the applicable EPC Contract and shall
          use
          commercially reasonable efforts to deliver to the Collateral Agent such
          other
          lien waivers from such contractors and subcontractors as shall be reasonably
          requested by the Collateral Agent and (iii) a Survey of such Mortgaged
          Property

          Applicable Laws (including state and federal Environmental Laws and regulatory

          Indebtedness being refinanced, or any guarantee thereof, constituted
          subordinated Indebtedness, then such replacement or refinancing Indebtedness,
          or
          such guarantee, respectively, shall be subordinated to the Obligations
          to
          substantially the same extent; and

Section 10.5(v) and (II) loans and advances to any direct or
          indirect parent of the Borrower made pursuant to Section 10.5(m),
          not in excess of the sum of (1) $500,000,000 plus (2) the Applicable
          Equity Amount at the time of such prepayment, repurchase, redemption or
          other
          defeasance plus (3) to the extent the Consolidated Secured Debt to
          Consolidated EBITDA Ratio is not greater than 5.0 to 1.0 on a Pro Forma
          Basis,
          to the making of such prepayment, repurchase, redemption or defeasance,
          the
          Applicable Amount at the time of such prepayment, repurchase, redemption
          or
          other defeasance; (ii) in the case of Permitted Additional Debt, with the
          proceeds of other Permitted Additional Debt and (iii) in the case of the

          foregoing, nothing in this Section 10.7 shall prohibit (A) the repayment
          or prepayment of intercompany subordinated Indebtedness owed among the
          Borrower
          and/or the Restricted Subsidiaries, in either case unless a Default or
          an Event
          of Default has occurred and is continuing and the Borrower has received
          a notice
          from the Collateral Agent instructing it not to make or permit any such
          repayment or prepayment or (B) transfers of credit positions in connection
          with
          intercompany debt restructurings so long as such Indebtedness is permitted
          by
Section 10.1 after giving effect to such transfer.  For the
          avoidance of doubt, nothing in this Section 10.7 shall restrict the
          making of any prepayment of accrued but unpaid interest and/or original
          issue
          discount in respect of either the Borrower Senior Facility or any Refinanced
          Bridge Indebtedness Documentation in accordance with “Optional Interest
          Repayment” provisions thereof at the end of any accrued period ending after the
          fifth anniversary of the Closing Date.

         

        (b)           The
          Borrower will not, and will not permit to the Restricted Subsidiaries to
          waive,
          amend, modify, terminate or release any Permitted Additional Debt that
          is
          subordinated to the Obligations, any Limited Notes or the Borrower Senior
          Interim Loan Agreement, in each case, that to the extent that any such
          waiver,
          amendment, modification, termination or release, taken as a whole, would
          be
          adverse to the Lenders in any material respect.

         

        10.8.           Limitations
          on Sale Leasebacks

         

        .  The
          Borrower will not, and will not permit the Restricted Subsidiaries to,
          enter
          into or effect any Sale Leasebacks after the Closing Date, other than Permitted
          Sale Leasebacks.

          respective obligations under any netting and/or settlement agreement with

          required to be prepaid other than by a regularly scheduled required prepayment
          (other than any Hedging Obligations or Indebtedness under any Permitted
          Receivables Financing) or as a mandatory prepayment, prior to the stated
          maturity thereof; provided that this clause (b) shall not apply to
          secured Indebtedness that becomes due as a result of the voluntary sale

          (i) such pro forma adjustment to Consolidated EBITDA shall be given solely
          for
          the purpose of determining the existence of a Default or Event of Default

          the covenant set forth in such Section with respect to any Test Period
          that
          includes the fiscal quarter for which such Cure Right was exercised and

          any other purpose under any Credit Document and (ii) no other adjustment
          under
          any other financial definition shall be made as a result of the exercise

          the purposes of Section 7), the Borrower shall be deemed to have
          satisfied the requirements of such covenant as of the relevant date of
          determination with the same effect as though there had been no failure
          to comply
          therewith at such date, and the applicable Default or Event of Default
          under
Section 11.3 that had occurred shall be deemed cured for purposes

          one fiscal quarter for which no Cure Right is exercised and (ii) with respect

          any exercise of the Cure Right, the Cure Amount shall be no greater than
          the
          amount required to cause the Borrower to be in compliance with the covenant
          set
          forth in Section 10.9.

          not have
          any duties or responsibilities except those expressly set forth herein
          or in any
          other Credit Document, any fiduciary relationship with any of the Administrative
          Agent, the Posting Agent, the Lenders, the Swingline Lender or the Letter
          of
          Credit Issuers or any agency or trust obligations with respect to any Credit
          Party, and no implied covenants, functions, responsibilities, duties,
          obligations or liabilities shall be read into this Agreement or any other
          Credit
          Document or otherwise exist against the Collateral Agent.

          execute any of its duties under this Agreement and the other Credit Documents
          by
          or through agents, sub-agents, employees or attorneys-in-fact and shall
          be
          entitled to advice of counsel concerning all matters pertaining to such
          duties.  Neither the Administrative Agent, the Posting Agent nor the

          of any
          agents, sub-agents or attorneys-in-fact selected by it in the absence of
          gross
          negligence or willful misconduct (as determined in the final judgment of
          a court
          of competent jurisdiction).

         

        12.3.           Exculpatory
          Provisions

         

        .

         

        (a)           No
          Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
          or Affiliates shall be (a) liable for any action lawfully taken or omitted
          to be
          taken by any of them under or in connection with this Agreement or any
          other
          Credit Document (except for its or such Person’s own gross negligence or willful
          misconduct, as determined in the final judgment of a court of competent
          jurisdiction, in connection with its duties expressly set forth herein)
          or (b)
          responsible in any manner to any of the Lenders or any participant for
          any
          recitals, statements, representations or warranties made by any of US Holdings,
          the Borrower, any other Guarantor, any other Credit Party or any officer
          thereof
          contained in this Agreement or any other Credit Document or in any certificate,
          report, statement or other document referred to or provided for in, or
          received
          by such Agent under or in connection with, this Agreement or any other
          Credit
          Document or for the value, validity, effectiveness, genuineness, enforceability
          or sufficiency of this Agreement or any other Credit Document, or the perfection
          or priority of any Lien or security interest created or purported to be
          created
          under the Security Documents, or for any failure of US Holdings, the Borrower,
          any other Guarantor or any other Credit Party to perform its obligations
          hereunder or thereunder.  No Agent shall be under any obligation to
          any Lender to ascertain or to inquire as to the observance or performance
          of any
          of the agreements contained in, or conditions of, this Agreement or any
          other
          Credit Document, or to inspect the properties, books or records of any
          Credit
          Party or any Affiliate thereof.  The Collateral Agent shall not be
          under any obligation to the Administrative Agent, the Posting Agent, any
          Lender
          or any Letter of Credit Issuer to ascertain or to inquire as to the observance
          or performance of any of the agreements contained in, or conditions of,
          this
          Agreement or any other Credit Document, or to inspect the properties, books
          or
          records of any Credit Party.

         

        (b)           Each
          Lender confirms to the Administrative Agent, the Posting Agent, each other
          Lender and each of their respective Related Parties that it (i) possesses
          (individually or through its Related Parties) such knowledge and experience
          in
          financial and business matters that it is capable, without reliance on
          the
          Administrative Agent, the Posting Agent, any other Lender or any of their
          respective Related Parties, of evaluating the merits and risks (including
          tax,
          legal, regulatory, credit, accounting and other financial matters) of (x)
          entering into this Agreement, (y) making Loans, making Posting Advances
          and
          other extensions of credit hereunder and under the other Credit Documents
          and
          (z) in taking or not taking actions hereunder and thereunder, (ii) is
          financially able to bear such risks and (iii) has determined that entering
          into
          this Agreement and making Loans, making Posting Advances and other extensions
          of
          credit hereunder and under the other Credit Documents is suitable and
          appropriate for it.

         

        (c)           Each
          Lender acknowledges that (i) it is solely responsible for making its own
          independent appraisal and investigation of all risks arising under or in
          connection with this Agreement and the other Credit Documents, (ii) that
          it has,
          independently and without reliance upon the Administrative

        Agent,
          the Posting Agent, any other Lender or any of their respective Related
          Parties,
          made its own appraisal and investigation of all risks associated with,
          and its
          own credit analysis and decision to enter into, this Agreement based on
          such
          documents and information, as it has deemed appropriate and (iii) it will,
          independently and without reliance upon the Administrative Agent, the Posting
          Agent, any other Lender or any of their respective Related Parties, continue
          to
          be solely responsible for making its own appraisal and investigation of
          all
          risks arising under or in connection with, and its own credit analysis
          and
          decision to take or not take action under, this Agreement and the other
          Credit
          Documents based on such documents and information as it shall from time
          to time
          deem appropriate, which may include, in each case:

         

        (i)       the
          financial condition, status and capitalization of the Borrower and each
          other
          Credit Party;

         

        (ii)                  the
          legality, validity, effectiveness, adequacy or enforceability of this Agreement
          and each other Credit Document and any other agreement, arrangement or
          document
          entered into, made or executed in anticipation of, under or in connection
          with
          any Credit Document;

         

        (iii)                  determining
          compliance or non-compliance with any condition hereunder to the making
          of a
          Loan or Posting Advance, or the issuance of a Letter of Credit and the
          form and
          substance of all evidence delivered in connection with establishing the
          satisfaction of each such condition;

         

        (iv)                  the
          adequacy, accuracy and/or completeness of any information delivered by
          the
          Administrative Agent, the Posting Agent, any other Lender or by any of
          their
          respective Related Parties under or in connection with this Agreement or
          any
          other Credit Document, the transactions contemplated hereby and thereby
          or any
          other agreement, arrangement or document entered into, made or executed
          in
          anticipation of, under or in connection with any Credit Document.

         

        12.4.           Reliance
          by Agents

         

        .  The
          Administrative Agent, the Posting Agent and the Collateral Agent shall
          be
          entitled to rely, and shall be fully protected in relying, upon any writing,
          resolution, notice, consent, certificate, affidavit, letter, telecopy,
          telex,
          electronic mail, or teletype message, statement, order or other document
          or
          instruction believed by it to be genuine and correct and to have been signed,
          sent or made by the proper Person or Persons and upon advice and statements
          of
          legal counsel (including counsel to US Holdings and/or the Borrower),
          independent accountants and other experts selected by the Administrative
          Agent,
          the Posting Agent or the Collateral Agent.  The Administrative Agent
          and the Posting Agent may deem and treat the Lender specified in the Register
          with respect to any amount owing hereunder as the owner thereof for all
          purposes
          unless a written notice of assignment, negotiation or transfer thereof
          shall
          have been filed with the Administrative Agent and the Posting
          Agent.  The Administrative Agent, the Posting Agent and the Collateral
          Agent shall be fully justified in failing or refusing to take any action
          under
          this Agreement or any other Credit Document unless it shall first receive
          such
          advice or concurrence of the Required Lenders (or the Required Posting
          Lenders,
          as applicable) as it deems appropriate or it shall first be indemnified
          to its
          satisfaction by the Lenders against any and all liability and expense that
          may
          be incurred by it by reason of taking or continuing to take any such
          action.  The Administrative Agent, the Posting Agent and the
          Collateral Agent shall in all cases be fully protected in acting, or in
          refraining from acting, under this Agreement and the other Credit Documents
          in
          accordance with a request of the Required Lenders (or the Required Posting
          Lenders, as applicable), and such request and any action taken or failure
          to act
          pursuant thereto shall be binding upon all the Lenders and all future holders
          of
          the Loans and/or Posting Advances; provided that the Administrative
          Agent, the Posting Agent and Collateral Agent shall not be required to
          take any
          action that, in its opinion or in the opinion of its counsel, may expose
          it to
          liability or that is contrary to any Credit Document or Applicable
          Law.  For purposes of determining compliance with the conditions
          specified in Sections 6 and 7 on the Closing

         

        
          
             

          

          
            -158-

            
              

            

          

          
             

          

        

        Date,
          each Lender that has signed this Agreement shall be deemed to have consented
          to,
          approved or accepted or to be satisfied with, each document or other matter
          required thereunder to be consented to or approved by or acceptable or
          satisfactory to a Lender unless the Administrative Agent shall have received
          notice from such Lender prior to the proposed Closing Date specifying its
          objection thereto.

         

        12.5.           Notice
          of Default

         

        .  Neither
          the Administrative Agent, the Posting Agent nor the Collateral Agent shall
          be
          deemed to have knowledge or notice of the occurrence of any Default or
          Event of
          Default hereunder unless the Administrative Agent, the Posting Agent or
          Collateral Agent, as applicable, has received notice from a Lender, US
          Holdings
          or the Borrower referring to this Agreement, describing such Default or
          Event of
          Default and stating that such notice is a “notice of default”.  In the
          event that the Administrative Agent or the Posting Agent receives such
          a notice,
          it shall give notice thereof to the Lenders, the Administrative Agent,
          the
          Posting Agent and the Collateral Agent.  The Administrative Agent and
          the Posting Agent shall take such action with respect to such Default or
          Event
          of Default as shall be reasonably directed by the Required Lenders (or
          Required
          Posting Lenders, as applicable); provided that unless and until the
          Administrative Agent or the Posting Agent shall have received such directions,
          the Administrative Agent and the Posting Agent may (but shall not be obligated
          to) take such action, or refrain from taking such action, with respect
          to such
          Default or Event of Default as is within its authority to take under this
          Agreement and otherwise as it shall deem advisable in the best interests
          of the
          Lenders except to the extent that this Agreement requires that such action
          be
          taken only with the approval of the Required Lenders (or the Required Posting
          Lenders, as applicable) or each of the Lenders, as applicable.

         

        12.6.           Non-Reliance
          on Administrative Agent, the Posting Agent, Collateral Agent and Other
          Lenders

         

        .  Each
          Lender expressly acknowledges that neither the Administrative Agent, the
          Posting
          Agent nor the Collateral Agent nor any of their respective officers, directors,
          employees, agents, attorneys-in-fact or Affiliates has made any representations
          or warranties to it and that no act by the Administrative Agent, the Posting
          Agent or Collateral Agent hereinafter taken, including any review of the
          affairs
          of US Holdings, the Borrower, any other Guarantor or any other Credit Party,
          shall be deemed to constitute any representation or warranty by the
          Administrative Agent, the Posting Agent or Collateral Agent to any Lender
          or the
          Letter of Credit Issuer.  Each Lender and the Letter of Credit Issuer
          represents to the Administrative Agent, the Posting Agent and the Collateral
          Agent that it has, independently and without reliance upon the Administrative
          Agent, Collateral Agent, the Posting Agent or any other Lender, and based
          on
          such documents and information as it has deemed appropriate, made its own
          appraisal of and investigation into the business, operations, property,
          financial and other condition and creditworthiness of US Holdings, the
          Borrower,
          each other Guarantor and each other Credit Party and made its own decision
          to
          make its Loans and/or Posting Advances hereunder and enter into this
          Agreement.  Each Lender also represents that it will, independently
          and without reliance upon the Administrative Agent, Collateral Agent, the
          Posting Agent or any other Lender, and based on such documents and information
          as it shall deem appropriate at the time, continue to make its own credit
          analysis, appraisals and decisions in taking or not taking action under
          this
          Agreement and the other Credit Documents, and to make such investigation
          as it
          deems necessary to inform itself as to the business, operations, property,
          financial and other condition and creditworthiness of US Holdings, the
          Borrower,
          each other Guarantor and each other Credit Party.  Except for notices,
          reports and other documents expressly required to be furnished to the Lenders
          by
          the Administrative Agent or the Posting Agent hereunder, neither the
          Administrative Agent, the Posting Agent nor the Collateral Agent shall
          have any
          duty or responsibility to provide any Lender with any credit or other
          information concerning the business, assets, operations, properties, financial
          condition, prospects or creditworthiness of US Holdings, the Borrower,
          any other
          Guarantor or any other Credit Party that may come into the possession of
          the
          Administrative Agent, the Posting Agent or Collateral Agent any of their
          respective officers, directors, employees, agents, attorneys-in-fact or
          Affiliates.

        12.7.           Indemnification

         

        .  The
          Lenders agree to indemnify each Agent, each in its capacity as such (to
          the
          extent not reimbursed by the Credit Parties and without limiting the obligation
          of the Credit Parties to do so), ratably according to their respective
          portions
          of the Total Credit Exposure in effect on the date on which indemnification
          is
          sought (or, if indemnification is sought after the date upon which the
          Commitments shall have terminated and the Loans and Posting Advances shall
          have
          been paid in full, ratably in accordance with their respective portions
          of the
          Total Credit Exposure in effect immediately prior to such date), from and
          against any and all liabilities, obligations, losses, damages, penalties,
          actions, judgments, suits, costs, expenses or disbursements of any kind
          whatsoever that may at any time occur (including at any time following
          the
          payment of the Loans and the Posting Advances) be imposed on, incurred
          by or
          asserted against such Agent in any way relating to or arising out of the
          Commitments, this Agreement, any of the other Credit Documents or any documents
          contemplated by or referred to herein or therein or the transactions
          contemplated hereby or thereby or any action taken or omitted by such Agent
          under or in connection with any of the foregoing (SUBJECT TO THE PROVISO
          BELOW, WHETHER OR NOT CAUSED BY OR ARISING IN WHOLE OR IN  PART, OUT
          OF THE COMPARATIVE, CONTRIBUTORY OR SOLE ORDINARY NEGLIGENCE OF THE INDEMNIFIED
          PARTY); provided that no Lender shall be liable to any Agent for
          the payment of any portion of such liabilities, obligations, losses, damages,
          penalties, actions, judgments, suits, costs, expenses or disbursements
          resulting
          from such Agent’s gross negligence or willful misconduct as determined by a
          final judgment of a court of competent jurisdiction; provided,
further, that no action taken in accordance with the directions
          of the
          Required Lenders (or such other number or percentage of the Lenders as
          shall be
          required by the Credit Documents) shall be deemed to constitute gross negligence
          or willful misconduct for purposes of this
Section 12.7.  In the case of any investigation,
          litigation or proceeding giving rise to any liabilities, obligations, losses,
          damages, penalties, actions, judgments, suits, costs, expenses or disbursements
          of any kind whatsoever that may at any time occur, be imposed upon, incurred
          by
          or asserted against the Administrative Agent, the Posting Agent or the
          Collateral Agent in any way relating to or arising out of the Commitments,
          this
          Agreement, any of the other Credit Documents or any documents contemplated
          by or
          referred to herein or therein or the transactions contemplated hereby or
          thereby
          or any action taken or omitted by such Agent under or in connection with
          any of
          the foregoing (including at any time following the payment of the Loans
          and
          Posting Advances), this Section 12.7 applies whether any such
          investigation, litigation or proceeding is brought by any Lender or any
          other
          Person.  Without limitation of the foregoing, each Lender shall
          reimburse such Agent upon demand for its ratable share of any costs or
          out-of-pocket expenses (including attorneys’ fees) incurred by such Agent in
          connection with the preparation, execution, delivery, administration,
          modification, amendment or enforcement (whether through negotiations, legal
          proceedings or otherwise) of, or legal advice rendered in respect of rights
          or
          responsibilities under, this Agreement, any other Credit Document, or any
          document contemplated by or referred to herein, to the extent that such
          Agent is
          not reimbursed for such expenses by or on behalf of the Borrower;
provided that such reimbursement by the Lenders shall not affect the
          Borrower’s continuing reimbursement obligations with respect
          thereto.  If any indemnity furnished to any Agent for any purpose
          shall, in the opinion of such Agent, be insufficient or become impaired,
          such
          Agent may call for additional indemnity and cease, or not commence, to
          do the
          acts indemnified against until such additional indemnity is furnished;
          provided in no event shall this sentence require any Lender to indemnify
          any Agent against any liability, obligation, loss, damage, penalty, action,
          judgment, suit, cost, expense or disbursement in excess of such Lender’s pro
          rata portion thereof; and providedfurther, this sentence
          shall not be deemed to require any Lender to indemnify any Agent against
          any
          liability, obligation, loss, damage, penalty, action, judgment, suit, cost,
          expense or disbursement resulting from such Agent’s gross negligence or willful
          misconduct (as determined by a final judgment of court of competent
          jurisdiction).  The agreements in this Section 12.7 shall
          survive the payment of the Loans, the Posting Advances and all other amounts
          payable hereunder.

        12.8.           Agents
          in its Individual Capacities

         

        .  Each
          Agent and its Affiliates may make loans to, accept deposits from and generally
          engage in any kind of business with US Holdings, the Borrower, any other
          Guarantor, and any other Credit Party as though such Agent were not an
          Agent
          hereunder and under the other Credit Documents.  With respect to the
          Loans or Posting Advances made by it, each Agent shall have the same rights
          and
          powers under this Agreement and the other Credit Documents as any Lender
          and may
          exercise the same as though it were not an Agent, and the terms “Lender” and
“Lenders” shall include each Agent in its individual capacity.

         

        12.9.           Successor
          Agents

         

        .  (b)
          Each of the Administrative Agent and Collateral Agent may resign at any
          time by
          notifying the other Agent, the Lenders, the Letter of Credit Issuers and
          the
          Borrower.  Upon receipt of any such notice of resignation, the
          Required Lenders shall have the right, subject to the consent of the Borrower
          (not to be unreasonably withheld or delayed), to appoint a successor, which
          shall be a bank with an office in the United States, or an Affiliate of
          any such
          bank with an office in the United States.  If no such successor shall
          have been so appointed by the Required 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 the
          Letter
          of Credit Issuers, appoint a successor Agent meeting the qualifications
          set
          forth above; provided that if such Agent shall notify the Borrower and
          the Lenders that no qualifying person has accepted such appointment, then
          such
          resignation shall nonetheless become effective in accordance with such
          notice
          and (x) the retiring Agent shall be discharged from its duties and obligations
          hereunder and under the other Credit Documents (except that in the case
          of any
          collateral security held by the Collateral Agent on behalf of the Secured
          Parties under any of the Credit Documents, the retiring Collateral Agent
          shall
          continue to hold such collateral security until such time as a successor
          Collateral Agent is appointed) and (y) all payments, communications and
          determinations provided to be made by, to or through such Agent shall instead
          be
          made by or to each Lender and the Letter of Credit Issuer directly, until
          such
          time as the Required Lenders with (except after the occurrence and during
          the
          continuation of a Default or Event of Default) the consent of the Borrower
          (not
          to be unreasonably withheld) appoint successor Agents as provided for above
          in
          this paragraph.  Upon the acceptance of a successor’s appointment as
          the Administrative Agent or Collateral Agent, as the case may be, hereunder,
          and
          upon the execution and filing or recording of such financing statements,
          or
          amendments thereto, and such amendments or supplements to the Mortgages,
          and
          such other instruments or notices, as may be necessary or desirable, or
          as the
          Required Lenders may request, in order to continue the perfection of the
          Liens
          granted or purported to be granted by the Security Documents, such successor
          shall succeed to and become vested with all of the rights, powers, privileges
          and duties of the retiring (or retired) Agent, and the retiring Agent shall
          be
          discharged from all of its duties and obligations hereunder or under the
          other
          Credit Documents (if not already discharged therefrom as provided above
          in this
          Section).  The fees payable by the Borrower (following the
          effectiveness of such appointment) to such Agent shall be the same as those
          payable to its predecessor unless otherwise agreed between the Borrower
          and such
          successor.  After the retiring Agent’s resignation hereunder and under
          the other Credit Documents, the provisions of this Section 12 (including
12.7) and Section 13.5 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
          the
          retiring Agent was acting as an Agent.

         

        (b)           Without
          limitation to Section 3.6(a) or 13.9, any resignation by Citibank,
          N.A. as Administrative Agent pursuant to this Section 12.9 shall also
          constitute its resignation as a Letter of Credit Issuer and Swingline
          Lender.  Upon the acceptance of a successor’s appointment as
          Administrative Agent hereunder, (a) such successor shall succeed to and
          become vested with all of the rights, powers, privileges and duties of
          the
          retiring Letter of Credit Issuer and Swingline Lender, (b) the retiring
          Letter of Credit Issuer and Swingline Lender shall be discharged from all
          of
          their respective duties and obligations hereunder or under the other Credit
          Documents, and (c) the successor Letter of Credit Issuer shall issue
          letters of credit in substitution for the Letters of Credit, if any, outstanding
          at the time of such succession

         

        
          
             

          

          
            -161-

            
              

            

          

          
             

          

        

        or
          make other arrangements satisfactory to the retiring Letter of Credit Issuer
          to
          effectively assume the obligations of the retiring Letter of Credit Issuer
          with
          respect to such Letters of Credit.

         

        (c)           The
          Posting Agent may resign at any time by giving 30 days’ prior written notice to
          the Posting Lenders and the Borrower.  Upon any such resignation, the
          Required Posting Lenders shall have the right to appoint a successor Posting
          Agent acceptable to the Borrower.  If no successor shall have been so
          appointed by the Required Posting Lenders and shall have accepted such
          appointments within 30 days after the Posting Agent gives notice of its
          resignation, then the Posting Agent may, on behalf of the Posting Lenders,
          appoint a successor Posting Agent, having a combined capital and surplus
          of at
          least $500,000,000 or an Affiliate of any such bank and in any case, the
          Posting
          Agent’s resignation shall become effective on the 30th day after such notice
          of
          resignation.  If neither the Required Posting Lenders nor the Posting
          Agent shall have appointed a successor Posting Agent within 30 days of
          the date
          of such notice of resignation, the Required Posting Lenders shall be deemed
          to
          succeed to and become vested with all the rights, powers, privileges and
          duties
          of the retiring Posting Agent until such time as the Required Posting Lenders
          appoint a successor Posting Agent in accordance with this paragraph and
          such
          successor Posting Agent accepts such appointment.  Upon the acceptance
          of any appointment as Posting Agent hereunder by a successor bank (or the
          Required Posting Lenders have been deemed to succeed the retiring Posting
          Agent
          pursuant to the immediately preceding sentence), such successor shall succeed
          to
          and become vested with all the rights, powers, privileges and duties of
          the
          retiring Posting Agent and the Posting Agent shall be discharged from its
          duties
          and obligations hereunder.  After the Posting Agent’s resignation
          hereunder, the provisions of this paragraph and Sections 12.7, 13.5 and
          14.11
          shall continue in effect for its benefit in respect of any actions taken
          or
          omitted to be taken by it while it was acting as the Posting
          Agent.  The Posting Calculation Agent and the Posting Lenders agree
          that unless the Borrower otherwise consents in writing, the Posting Calculation
          Agent may not resign as the Posting Calculation Agent.

         

        12.10.                      Withholding
          Tax

         

        .  To
          the extent required by any Applicable Law, the Administrative Agent (or,
          with
          respect to the Posting Facility, the Posting Agent) may withhold from any
          interest payment to any Lender an amount equivalent to any applicable
          withholding tax.  If the Internal Revenue Service or any authority of
          the United States or other jurisdiction asserts a claim that the Administrative
          Agent (or, with respect to the Posting Facility, the Posting Agent) did
          not
          properly withhold tax from amounts paid to or for the account of any Lender
          (because the appropriate form was not delivered, was not properly executed,
          or
          because such Lender failed to notify the Administrative Agent or (or, with
          respect to the Posting Facility, the Posting Agent) of a change in circumstances
          that rendered the exemption from, or reduction of, withholding tax ineffective,
          or for any other reason), such Lender shall indemnify the Administrative
          Agent
          (or, with respect to the Posting Facility, the Posting Agent) (to the extent
          that the Administrative Agent (or, with respect to the Posting Facility,
          the
          Posting Agent) has not already been reimbursed by the Borrower (solely
          to the
          extent required by this Agreement) and without limiting the obligation
          of the
          Borrower to do so) fully for all amounts paid, directly or indirectly,
          by the
          Administrative Agent (or, with respect to the Posting Facility, the Posting
          Agent) as tax or otherwise, including penalties and interest, together
          with all
          expenses incurred, including legal expenses, allocated staff costs and
          any out
          of pocket expenses.

          Indenture Act

         

        .  In
          the event that Citibank, N.A. or any of its Affiliates shall be or become
          an
          indenture trustee under the Trust Indenture Act of 1939 (as amended, the
          “Trust Indenture Act”) in respect of any securities issued or
          guaranteed by any Credit Party, and agree that any payment or property
          received
          in satisfaction of or in respect of any Obligation of such Credit Party
          hereunder or under any other Credit Document by or on behalf of Citibank,
          N.A.,
          in its capacity as the Administrative Agent or the Collateral Agent for
          the
          benefit of any Lender or Secured Party under any Credit Document (other
          than
          Citibank, N.A. or an Affiliate of Citibank, N.A.) and which is applied
          in
          accordance with

        the
          Credit Documents shall be deemed to be exempt from the requirements of
          Section
          311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust
          Indenture Act.

         

        12.12.                      Intercreditor
          Agreement

         

        .  The
          Collateral Agent is hereby authorized to enter into the Intercreditor Agreement,
          and the parties hereto acknowledge that the Intercreditor Agreement is
          binding
          upon them.  Each Lender (a) hereby agrees that it will be bound by and
          will take no actions contrary to the provisions of the Intercreditor Agreement
          and (b) hereby authorizes and instructs the Collateral Agent to enter into
          the
          Intercreditor Agreement and to subject the Liens on the Collateral securing

          to the
          Intercreditor Agreement and (ii) any other intercreditor arrangements,
          in the
          case of clauses (i) and (ii) to the extent required to give effect
          to the establishment of intercreditor rights and privileges as contemplated
          and
          required by Section 10.2 of this Agreement.

         

        12.13.                      Security
          Documents and Guarantee

         

        .  iv) Agents

          for and
          representative of the Secured Parties with respect to the Collateral and
          the
          Security Documents.  Subject to Section 13.1, without further
          written consent or authorization from any Secured Party, the Administrative
          Agent or Collateral Agent, as applicable, may execute any documents or
          instruments necessary to in connection with a sale or disposition of assets
          permitted by this Agreement, (i) release any Lien encumbering any item of
          Collateral that is the subject of such sale or other disposition of assets,

          required
          to give such consent under Section 13.1) have otherwise consented or (ii)
          release any Guarantor from the Guarantee, or with respect to which Required
          Lenders (or such other Lenders as may be required to give such consent
          under
Section 13.1) have otherwise consented.

         

        (b)           Right
          to Realize on Collateral and Enforce Guarantee.  Anything
          contained in any of the Credit Documents to the contrary notwithstanding,
          US
          Holdings, the Borrower, the Agents and each Secured Party hereby agree
          that (i)

          that all
          powers, rights and remedies hereunder may be exercised solely by the

          hereof and all powers, rights and remedies under the Security Documents
          and
          Guarantee may be exercised solely by the Collateral Agent, on behalf of
          the
          Secured Parties, and (ii) in the event of a foreclosure by the Collateral
          Agent

          disposition, the Collateral Agent or any Secured Party may be the purchaser

        Any

          to
          approve or disapprove any amendment, modification, supplement, waiver or
          consent
          hereunder, except that the Commitment of such Lender may not be increased
          or
          extended without the consent of such Lender (it being understood that any
          Commitments, Loans or Posting Advances held or deemed held by any Defaulting
          Lender shall be excluded for a vote of the Lenders hereunder requiring
          any
          consent of the Lenders, except as expressly provided for by this
          Agreement).

         

        Notwithstanding
          the foregoing, in addition to any credit extensions and related Incremental
          Amendment(s) effectuated without the consent of Lenders in accordance with
          Section 2.14, this Agreement may be amended (or amended and

          more
          additional credit facilities to this Agreement and to permit the extensions
          of

          and
          the other Credit Documents with the Loans, Posting Advances and Commitments
          and
          the accrued interest and Fees in respect thereof and (b) to include
          appropriately the Lenders holding such credit facilities in any determination
          of
          the Required Lenders and other definitions related to such new Loans, Posting
          Advances and Commitments.

          shall be substantially identical to, or less favorable to the Lenders providing
          such Replacement Term Loans than those applicable to such Refinanced Term
          Loans,
          except to the extent necessary to provide for covenants and other terms
          applicable to any period after the latest final maturity of the Term Loans

          life
          to maturity of such Replacement Deposit L/C Loans shall not be shorter
          than the
          weighted average life to maturity of such Refinanced Deposit L/C Loans

          another Credit Party, to the extent such sale or other disposition is made
          in
          compliance with the terms of this Agreement (and the Collateral Agent may
          rely
          conclusively on a certificate to that effect provided to it by any Credit
          Party

          whose consent may be required in accordance with this Section 13.1),
          (v) to the extent the property constituting such Collateral is owned by any
          Subsidiary Guarantor, upon the release of such Subsidiary Guarantor from
          its

          connection with any exercise of remedies of the Collateral Agent pursuant
          to the
          Collateral Documents.  Any such release shall not in any manner
          discharge, affect or impair the Obligations or any Liens (other than those
          being
          released) upon (or obligations (other than those being released) of the
          Credit
          Parties in respect of) all interests retained by the Credit Parties, including
          the proceeds of any sale, all of which shall continue to constitute part
          of the
          Collateral except to the extent otherwise released in accordance with the
          provisions of the Credit Documents.  Additionally, the Lenders hereby
          irrevocably agree that the Subsidiary Guarantors shall be released from
          the
          Guarantee upon consummation of any transaction resulting in such Subsidiary
          ceasing to constitute a Restricted Subsidiary.  The Lenders hereby
          authorize the Administrative Agent and the Collateral Agent, as applicable,
          to

          without
          the further consent or joinder of any Lender.

          the Posting Agent, in connection with the Posting Facility, in each case
          otherwise consents (which consents shall not be unreasonably withheld or
          delayed); provided that no such consent of the Borrower shall be required
          if an Event of Default under Section 11.1 or Section 11.5 has
          occurred and is continuing with respect to US Holdings or the Borrower;

          stated above;

         

        (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;
provided that this clause shall not be construed to prohibit the
          assignment of a proportionate part of all the assigning Lender’s rights and
          obligations in respect of one Class of Commitments, Posting Advances or
          Loans;

         

        (C)           The
          parties to each assignment shall execute and deliver to the Administrative
          Agent
          an Assignment and Acceptance, together with a processing and recordation
          fee in
          the amount of $3,500; provided that the Administrative Agent or the
          Posting Agent, as applicable. may, in its sole discretion, elect to waive
          such
          processing and recordation fee in the case of any assignment; and

         

        (D)           the

          to acceptance and recording thereof pursuant to clause (b)(iv) of
          this Section 13.6, from and after the effective date specified in each
          Assignment and Acceptance, the assignee thereunder shall be a party hereto

          to the extent of the interest assigned by such Assignment and Acceptance,
          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 Acceptance, be released from its obligations under this
          Agreement
          (and, in the case of an Assignment and Acceptance 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 2.10, 2.11, 3.5, 5.4 and
13.5).  Any assignment or transfer by a
          Lender of rights or
          obligations under this Agreement that does not comply with this
Section 13.6 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 clause (c) of this Section 13.6.

         

        (iv)           The

          Acceptance delivered to it and a register for the recordation of the names
          and
          addresses of the Lenders, and the Commitments of, and principal amount
          of the
          Loans, Posting Advances and any payment made by any Letter of Credit Issuer
          under any Letter of Credit owing to, each Lender pursuant to the terms
          hereof
          from time to time (the “Register”).  Further, each
          Register shall contain the name and address of the Administrative Agent
          and the
          lending office through which each such Person acts under this
          Agreement.  The entries in the Register shall be conclusive, and the

          Agent, the Letter of Credit Issuers and the Lenders shall 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 US
          Holdings, the Borrower, the Collateral Agent, the Posting Agent, the Letter
          of
          Credit Issuers 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 Acceptance 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 clause (b) of this
Section 13.6 (unless waived) and any written consent to such assignment
          required by clause (b) of this Section 13.6, the Administrative
          Agent shall accept such Assignment and Acceptance and record the information
          contained therein in the Register.

         

        (c)           (2)
          Any Lender may, without the consent of US Holdings, the Borrower, the
          Administrative Agent, the Posting Agent, any Letter of Credit Issuer or
          the
          Swingline Lender, sell participations to one or more banks or other entities
          (each, a “Participant”) in all or a portion of such Lender’s
          rights and obligations under this Agreement (including all or a portion
          of its
          Commitments, Posting Advances and the Loans owing to it); provided that
          (A) such Lender’s obligations under this Agreement shall remain unchanged, (B)
          such Lender shall remain solely responsible to the other parties hereto
          for the
          performance of such obligations and (C) US Holdings, the Borrower, the
          Administrative Agent, the Posting Agent, the Letter of Credit Issuers 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 or any other Credit Document;
          provided that such agreement or instrument may provide that such Lender
          will not, without the consent of the Participant, agree to any consent,
          amendment, modification, supplement or waiver described in clauses (i) or
(vii) of the second proviso of the first paragraph of Section 13.1
          that affects such Participant.  Subject to clause (c)(ii)
          of this Section 13.6, the Borrower agrees that each Participant shall be
          entitled to the benefits of Sections 2.10, 2.11 and 5.4 to
          the same extent as if it were a Lender, and provided that such Participant
          agrees to be subject to the requirements of those Sections as though it
          were a
          Lender and had acquired its interest by assignment pursuant to clause (b)
          of this Section 13.6  To the extent permitted by Applicable
          Law, each Participant also shall be entitled to the benefits of
Section 13.8(b) as though it were a Lender; provided such
          Participant agrees to be subject to Section 13.8(a) as though it were a
          Lender.

         

        (ii)           A
          Participant shall not be entitled to receive any greater payment under
          Section 2.10, 2.11, or 5.4 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 Borrower’s prior written consent (which consent shall not be
          unreasonably withheld or delayed).

         

        (iii)           Each
          Lender that sells a participation shall, acting for this purpose as an
          agent of
          the Borrower, maintain a register on which it enters the name and address
          of
          each participant and the principal amounts of each participant’s interest in the
          Loans or Posting Advances (or other rights or obligations) held by it (the
          “Participant Register”).  The entries in the
          Participant Register shall be conclusive, and such lender shall treat each
          Person whose  name is recorded in the Participant Register as the
          owner of such Loan, Posting Advance or other obligation hereunder as the
          owner
          thereof for all purposes of this Agreement notwithstanding any notice to
          the
          contrary.  Any such Participant Register shall be available for
          inspection by the Administrative Agent, the Posting Agent and the Borrower
          at
          any reasonable time and from time to time upon reasonable prior
          notice.

        (d)           Any
          Lender may, without the consent of US Holdings, the Borrower, the Administrative
          Agent or the Posting Agent, 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 13.6 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.  In order to facilitate such pledge or assignment
          or for any other reason, the Borrower hereby agrees that, upon request
          of any
          Lender at any time and from time to time after any Borrower has made its
          initial
          borrowing hereunder, the Borrower shall provide to such Lender, at the
          Borrower’s own expense, a promissory note, substantially in the form of
Exhibit K-1, K-2-A, K-2-B, K-2-C, K-3 or
K-4, evidencing the Revolving
          Credit Loans and Swingline Loans, Initial
          Tranche B-1 Term Loans, Initial Tranche B-2 Term Loans, Initial Tranche
          B-3 Term
          Loans, Delayed Draw Term Loans and Deposit L/C Loans, respectively, owing
          to
          such Lender.

         

        (e)           Subject
          to Section 13.16, the Borrower authorizes each Lender to disclose to any
          Participant, secured creditor of such Lender or assignee (each, a
“Transferee”), any prospective Transferee and any prospective
          direct or indirect contractual counterparties to any swap or derivative
          transactions to be entered into in connection with or relating to Loans
          or
          Posting Advances made hereunder any and all financial information in such
          Lender’s possession concerning the Borrower and its Affiliates that has been
          delivered to such Lender by or on behalf of the Borrower and its Affiliates
          pursuant to this Agreement or that has been delivered to such Lender by
          or on
          behalf of the Borrower and its Affiliates in connection with such Lender’s
          credit evaluation of the Borrower and its Affiliates prior to becoming
          a party
          to this Agreement.

         

        (f)           The
          words “execution,” “signed,” “signature,” and words of like import in any
          Assignment and Acceptance shall be deemed to include electronic signatures
          or
          the keeping of records in electronic form, each of which shall be of the
          same
          legal effect, validity or enforceability as a manually executed signature
          or the
          use of a paper-based recordkeeping system, as the case may be, to the extent
          and
          as provided for in any applicable law, including the Federal Electronic
          Signatures in Global and National Commerce Act, the New York State Electronic
          Signatures and Records Act, or any other similar state laws based on the
          Uniform
          Electronic Transactions Act.

         

        (g)           SPV
          Lender.  Notwithstanding anything to the contrary contained
          herein, any Lender (a “Granting Lender”) may grant to a special
          purpose funding vehicle (a “SPV”), identified as such in
          writing from time to time by the Granting Lender to the Administrative
          Agent and
          the Borrower, the option to provide to the Borrower all or any part of
          any Loan
          that such Granting Lender would otherwise be obligated to make the Borrower
          pursuant to this Agreement; provided that (i) nothing herein shall
          constitute a commitment by any SPV to make any Loan and (ii) if an SPV
          elects
          not to exercise such option or otherwise fails to provide all or any part
          of
          such Loan, the Granting Lender shall be obligated to make such Loan pursuant
          to
          the terms hereof.  The making of a Loan by an SPV hereunder shall
          utilize the Commitment of the Granting Lender to the same extent, and as
          if,
          such Loan were made by such Granting Lender.  Each party hereto hereby
          agrees that no SPV shall be liable for any indemnity or similar payment
          obligation under this Agreement (all liability for which shall remain with
          the
          Granting Lender).  In furtherance of the foregoing, each party hereto
          hereby agrees (which agreement shall survive the termination of this Agreement)
          that, prior to the date that is one year and one day after the payment
          in full
          of all outstanding commercial paper or other senior indebtedness of any
          SPV, it
          shall not institute against, or join any other person in instituting against,
          such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation
          proceedings under the laws of the United States or any State
          thereof.  In addition, notwithstanding anything to the contrary
          contained in this Section 13.6, any SPV may (i) with notice to, but
          without the prior written consent of, the Borrower and the Administrative
          Agent
          and with

        out
          paying any processing fee therefor, assign all or a portion of its interests
          in
          any Loans to the Granting Lender or to any financial institutions (consented
          to
          by the Borrower and Administrative Agent) providing liquidity and/or credit
          support to or for the account of such SPV to support the funding or maintenance
          of Loans and (ii) disclose on a confidential basis any non-public information
          relating to its Loans to any rating agency, commercial paper dealer or
          provider
          of any surety, guarantee or credit or liquidity enhancement to such
          SPV.  This Section 13.6(g) may not be amended without the
          written consent of the SPV.  Notwithstanding anything to the contrary
          in this Agreement, (x) no SPV shall be entitled to any greater rights under
          Sections 2.10, 2.11, and 5.4 than its Granting Lender would
          have been entitled to absent the use of such SPV and (y) each SPV agrees
          to be
          subject to the requirements of Sections 2.10, 2.11, and 5.4
          as though it were a Lender and has acquired its interest by assignment
          pursuant
          to clause (b) of this Section 13.6.

        (a)           The
          Borrower shall be permitted to replace any Lender that (a) requests
          reimbursement for amounts owing pursuant to Section 2.10, 3.5
          or 5.4, (b) is affected in the manner described in Section
          2.10(a)(iii) and as a result thereof any of the actions described in such
          Section is required to be taken or (c) becomes a Defaulting Lender, with
          a
          replacement bank or other financial institution; provided that (i) such
          replacement does not conflict with any Applicable Law, (ii) no Event of
          Default
          under Section 11.1 or 11.5 shall have occurred and be continuing
          at the time of such replacement, (iii) the Borrower shall repay (or the
          replacement bank or institution shall purchase, at par) all Loans, Posting
          Advances and other amounts (other than any disputed amounts), pursuant
          to
Section 2.10, 2.11, 3.5 or 5.4, as the case may
          be) owing to such replaced Lender prior to the date of replacement, (iv)
          the
          replacement bank or institution, if not already a Lender, and the terms
          and
          conditions of such replacement, shall be reasonably satisfactory to the
          Administrative Agent (or, in the case of any Posting Lender, the Posting
          Agent),
          (v) the replaced Lender shall be obligated to make such replacement in
          accordance with the provisions of Section 13.6 (provided that the
          Borrower shall be obligated to pay the registration and processing fee
          referred
          to therein) and (vi) any such replacement shall not be deemed to be a
          waiver of any rights that the Borrower, the Administrative Agent, the Posting
          Agent or any other Lender shall have against the replaced Lender.

         

        (b)           If
          any Lender (such Lender, a “Non-Consenting Lender”) has failed
          to consent to a proposed amendment, modification, supplement, waiver, discharge
          or termination that pursuant to the terms of Section 13.1 requires the
          consent of all of the Lenders or all Lenders affected and with respect
          to which
          the Required Lenders (or the Required Posting Lenders, as applicable) shall
          have
          granted their consent, then provided no Event of Default then exists, the
          Borrower shall have the right (unless such Non-Consenting Lender grants
          such
          consent) to replace such Non-Consenting Lender by requiring such Non-Consenting
          Lender to assign its Loans, Posting Advances and its Commitments hereunder
          to
          one or more assignees reasonably acceptable to the Administrative Agent
          or, with
          respect to the Posting Facility, the Posting Agent; provided
          that:  (a) all Obligations of the Borrower owing to such
          Non-Consenting Lender being replaced shall be paid in full to such
          Non-Consenting Lender concurrently with such assignment, and (b) the replacement
          Lender shall purchase the foregoing by paying to such Non-Consenting Lender
          a
          price equal to the principal amount thereof plus accrued and unpaid
          interest thereon.  In connection with any such assignment, the
          Borrower, Administrative Agent, the Posting Agent, such Non-Consenting
          Lender
          and the replacement Lender shall otherwise comply with Section
          13.6.

         

        13.8.           Adjustments;
          Set-off

         

        .

         

        (a)           If
          any Lender (a “benefited Lender”) shall at any time receive any
          payment of all or part of its Loans or Posting Advances, or interest thereon,
          or
          receive any collateral in respect thereof (whether voluntarily or involuntarily,
          by set-off, pursuant to events or proceedings of the nature
          referred

         

        
          
             

          

          
            -175-

            
              

            

          

          
             

          

        

        to
          in Section 11.5, or otherwise), in a greater proportion than any such
          payment to or collateral received by any other Lender, if any, in respect
          of
          such other Lender’s Loans or Posting Advances, or interest thereon, such
          benefited Lender shall purchase for cash from the other Lenders a participating
          interest in such portion of each such other Lender’s Loan or Posting Advance, or
          shall provide such other Lenders with the benefits of any such collateral,
          or
          the proceeds thereof, as shall be necessary to cause such benefited Lender
          to
          share the excess payment or benefits of such collateral or proceeds ratably
          with
          each of the Lenders; provided, however, that if all or any portion
          of such excess payment or benefits is thereafter recovered from such benefited
          Lender, such purchase shall be rescinded, and the purchase price and benefits
          returned, to the extent of such recovery, but without interest.

         

        (b)           After
          the occurrence and during the continuance of an Event of Default, in addition
          to
          any rights and remedies of the Lenders provided by Applicable Law, each
          Lender
          shall have the right, without prior notice to US Holdings, the Borrower,
          any
          such notice being expressly waived by US Holdings, the Borrower to the
          extent
          permitted by Applicable Law, upon any amount becoming due and payable by
          the
          Borrower hereunder (whether at the stated maturity, by acceleration or
          otherwise) to set-off and appropriate and apply against such amount any
          and all
          deposits (general or special, time or demand, provisional or final), in
          any
          currency, and any other credits, indebtedness or claims, in any currency,
          in
          each case whether direct or indirect, absolute or contingent, matured or
          unmatured, at any time held or owing by such Lender or any branch or agency
          thereof to or for the credit or the account of the Borrower.  Each
          Lender agrees promptly to notify the Borrower and the Administrative Agent
          after
          any such set-off and application made by such Lender; provided that the
          failure to give such notice shall not affect the validity of such set-off
          and
          application.

         

        13.9.           Counterparts

         

        .  This
          Agreement may be executed by one or more of the parties to this Agreement
          on any
          number of separate counterparts (including by facsimile or other electronic
          transmission), and all of said counterparts taken together shall be deemed
          to
          constitute one and the same instrument.  A set of the copies of this
          Agreement signed by all the parties shall be lodged with the Borrower and
          the
          Administrative Agent.

         

        13.10.                      Severability

         

        .  Any
          provision of this Agreement that is prohibited or unenforceable in any
          jurisdiction shall, as to such jurisdiction, be ineffective to the extent
          of
          such prohibition or unenforceability without invalidating the remaining
          provisions hereof, and any such prohibition or unenforceability in any
          jurisdiction shall not invalidate or render unenforceable such provision
          in any
          other jurisdiction.

          the Administrative Agent, the Posting Agent nor any other Agent has any
          obligation to disclose any of such interests by virtue of any advisory,

          or
          similar duty to US Holdings, the Borrower or any other Affiliates, in connection

          Communications in an electronic/soft medium in a format reasonably acceptable
          to

          that:  (i) upon written request by the Administrative Agent, US
          Holdings or the Borrower shall deliver paper copies of such documents to
          the
          Administrative Agent for further distribution to each Lender until a written
          request to cease delivering paper copies is given by the Administrative
          Agent
          and (ii) US Holdings or the Borrower shall notify (which may be by facsimile

          Administrative Agent at its e-mail address set forth above shall constitute
          effective delivery of the Communications to the Administrative Agent for

          it (as provided in the next sentence) specifying that the Communications
          have
          been posted to the Platform shall constitute effective delivery of the
          Communications to such Lender for purposes of the Credit

          in writing (including by electronic communication) from time to time of
          such
          Lender’s e-mail address to which the foregoing notice may be sent by electronic

          Communications available to the Lenders by posting the Communications on
          Intralinks or a substantially similar electronic transmission system (the
          “Platform”), so long as the access to such Platform is limited
          (i) to the Agents, the Letter of Credit Issuers, the Lenders or any bonafide
          potential Transferee and (ii) remains subject the confidentiality requirements
          set forth in Section 13.16.

          PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”.  THE AGENT PARTIES
          (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE
          COMMUNICATIONS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM
          LIABILITY
          FOR ERRORS IN OR OMISSIONS FROM THE COMMUNICATIONS.  NO WARRANTY OF
          ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF
          MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF

          PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY
          ANY AGENT
          PARTY IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM.  In no
          event shall any Agent or their Related Parties (collectively, the “Agent
          Parties” and each an “Agent Party”) have any liability
          to US Holdings, the Borrower, any Lender, any Letter of Credit Issuer or
          any
          other Person for losses, claims, damages, liabilities or expenses of any
          kind
          (whether in tort, contract or otherwise) arising out of US Holdings’, the
          Borrower’s or any Agent’s transmission of Communications through the internet,
          except to the extent the liability of any Agent Party resulted from such
          Agent
          Party’s (or any of its Related Parties’ (other than trustees or advisors)) gross
          negligence, bad faith or willful misconduct or material breach of the Credit
          Documents (as determined in a final non-appealable judgment of a court
          of
          competent jurisdiction).

         

        (e)           The
          Borrower and each Lender acknowledge that certain of the Lenders may be
          “public-side” Lenders (Lenders that do not wish to receive material non-public
          information with respect to US Holdings, the Borrower, the Subsidiaries
          of the
          Borrower or their securities) and, if documents or notices required to
          be
          delivered pursuant to the Credit Documents or otherwise are being distributed
          through the Platform, any document or notice that US Holdings or the Borrower
          has indicated contains only publicly available information with respect
          to US
          Holdings, the Borrower and the Subsidiaries of the Borrower and their securities
          may be posted on that portion of the Platform designated for such public-side
          Lenders.  If US Holdings or the Borrower has not indicated whether a
          document or notice delivered contains only publicly available information,
          the
          Administrative Agent shall post such document or notice solely on that
          portion
          of the Platform designated for Lenders who wish to receive material nonpublic
          information with respect to US Holdings, the Borrower, the Subsidiaries
          of the
          Borrower and their securities.  Notwithstanding the foregoing, US
          Holdings and the Borrower shall use commercially reasonable efforts to
          indicate
          whether any document or notice contains only publicly available
          information.

        .  Each
          Lender hereby notifies the Borrower that pursuant to the requirements of
          the USA
          Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26,
          2001)) (the “Patriot Act”), it is required to obtain, verify

        Party,
          which information includes the name and address of each Credit Party and
          other
          information that will allow such Lender to identify each Credit Party in
          accordance with the Patriot Act.

         

        13.19.                      Payments
          Set Aside

         

        .  To
          the extent that any payment by or on behalf of the Borrower is made to
          any Agent
          or any Lender, or any Agent or any Lender exercises its right of setoff,
          and
          such payment or the proceeds of such setoff or any part thereof is subsequently
          invalidated, declared to be fraudulent or preferential, set aside or required
          (including pursuant to any settlement entered into by such Agent or such
          Lender
          in its discretion) to be repaid to a trustee, receiver or any other party,
          in
          connection with any proceeding or otherwise, then (a) to the extent of
          such
          recovery, the obligation or part thereof originally intended to be satisfied
          shall be revived and continued in full force and effect as if such payment
          had
          not been made or such setoff had not occurred, and (b) each Lender severally
          agrees to pay to the Administrative Agent upon demand its applicable share
          of
          any amount so recovered from or repaid by any Agent, plus interest
          thereon from the date of such demand to the date such payment is made at
          a rate
          per annum equal to the applicable Overnight Rate from time to time in
          effect.

         

        13.20.                      Separateness

         

        .  v)
          The Secured Parties hereby acknowledge (i) the legal separateness of US
          Holdings, the Borrower and the Subsidiaries of the Borrower from the Oncor
          Subsidiaries, (ii) that the lenders under the Oncor Credit Facility and
          the
          noteholders under the Existing Oncor Notes and under the transition bonds
          have
          likely advanced funds thereunder in reliance upon the separateness of the
          Oncor
          Subsidiaries from US Holdings, the Borrower and the Subsidiaries of the
          Borrower, (iii) that the Oncor Subsidiaries have assets and liabilities
          that are
          separate from those of US Holdings, the Borrower and the Subsidiaries of
          the
          Borrower, (iv) that the Obligations are obligations and liabilities of
          the
          Borrower and the other Credit Parties only, and are not the obligations
          or
          liabilities of any of the Oncor Subsidiaries, (v) that the Secured Parties
          shall
          look solely to the Borrower and the Guarantors and such Persons’ assets, and not
          to any assets, or to the pledge of any assets, owned by any of the Oncor
          Subsidiaries, for the repayment of any amounts payable pursuant to this
          Agreement and for satisfaction of any other Obligations and (vi) that none
          of
          the Oncor Subsidiaries shall be personally liable to the Secured Parties
          for any
          amounts payable, or any other Obligation, under the Credit
          Documents.

         

        (b)           The
          Secured Parties hereby acknowledge and agree that the Secured Parties shall
          not
          (i) initiate any legal proceeding to procure the appointment of an
          administrative receiver, or (ii) institute any bankruptcy, reorganization,
          insolvency, winding up, liquidation, or any like proceeding under applicable
          law, against any of the Oncor Subsidiaries, or against any of the Oncor
          Subsidiaries’ assets.  The Secured Parties further acknowledge and
          agree that each of the Oncor Subsidiaries is a third party beneficiary
          of the
          forgoing covenant and shall have the right to specifically enforce such
          covenant
          in any proceeding at law or in equity.

        (a)           By
          no later than 9:00 p.m. (New York time) on each Business Day (unless it
          has been
          prevented from doing so due to a technical delay or failure (which shall
          not
          include a delay or failure that could have been reasonably avoided or for
          which
          alternative provision could reasonably have been made) or as a result of
          a
          Market Disruption Event), the Posting Calculation Agent shall determine
          the MTM
          Exposure as of the close of business on such Business Day.  Promptly
          after making such determination, it shall advise the Posting Agent and
          the
          Borrower of that determination in a form substantially similar to Exhibit
          P (each, a “Daily Notice”) (which Daily Notice shall be
          provided via email to the addresses of the Borrower and the Posting Agent
          set
          forth on Schedule 13.2).  If a Market Disruption
          Event

         

        
          
             

          

          
            -181-

            
              

            

          

          
             

          

        

        has
          occurred, then the Posting Calculation Agent shall, as promptly as reasonably
          practicable, determine the MTM Exposure in accordance with the Disruption
          Fallbacks and any other relevant provisions of the Commodity
          Definitions.  If such determination is prevented due to a technical
          delay or failure described above, the Posting Calculation Agent shall make
          such
          determination as promptly as reasonably practicable after such matter is
          remedied.

         

        (b)           After
          5:00 p.m. (New York time), on any Business Day, the Posting Calculation
          Agent
          shall endeavor, in a commercially reasonable manner, to estimate (based
          on such
          factors and information as it deems reasonably relevant and are then available
          to it) the MTM Exposure for such Business Day (the “Estimated MTM
          Exposure”) and provide the same to the Borrower and the Posting Agent
          (via email to the addresses of the Borrower and the Posting Agent set forth
          on
          Schedule 13.2); provided that (i) the Posting Calculation Agent shall not
          be
          required to provide such Estimated MTM Exposure within any specified time
          period, (ii) the Borrower  acknowledges that the Estimated MTM
          Exposure for any Business Day may differ significantly from the actual
          MTM
          Exposure determined by the Posting Calculation Agent for that Business
          Day
          pursuant to clause (a) above (the “Actual MTM Exposure”), (iii)
          that any difference between the Estimated MTM Exposure and the Actual MTM
          Exposure for any Business Day shall in no way limit or diminish the obligations
          of the Borrower, the Posting Agent, the Posting Lenders or the Posting
          Calculation Agent hereunder, which shall be based on the Actual MTM Exposure,
          (iv) the Borrower shall be solely responsible for whether and the extent to
          which it makes use of any Estimated MTM Exposure it receives and shall have no
          claim of any nature against the Posting Calculation Agent, the Posting
          Agent or
          any Lender as a result of or based on its use of such Estimated MTM Exposure
          or
          any difference between the Estimated MTM Exposure and the Actual MTM Exposure
          for any Business Day and (v) that the Posting Calculation Agent shall not
          be
          required, and shall have no obligation, to provide any backup data or other
          information supporting or reconciling any differences between an Estimate
          MTM
          Exposure and an Actual MTM Exposure.

         

        (c)           Without
          limiting clauses (a) and (b) above, the Borrower acknowledges that
          each Daily Notice and each Estimated MTM Exposure provided by the Posting
          Calculation Agent shall include, and be subject to, the Posting Calculation
          Agent’s standard disclaimer relating to mark-to-market calculations, a copy of
          which is set forth in Exhibit O hereto.

         

        14.3.           Computation
          of Posting Advance Amounts or Posting Repayment Amounts

         

        .

         

        (a)           The
          Posting Calculation Agent shall calculate the MTM Exposure as of the close
          of
          business on the Business Day immediately preceding the Closing Date (the
          “Closing Date MTM Exposure”) and shall provide the same to the
          Borrower in writing no later than 9:00 p.m. (New York time) on the day
          preceding
          the Closing Date.  The amount of the Posting Advance to be made on the
          Closing Date shall equal the Closing Date MTM Exposure (the “Initial
          Posting Advance Amount”).

         

        (b)           On
          each Computation Date, the Posting Calculation Agent shall determine the
          amount
          by which the MTM Exposure for that Computation Date is greater than or
          less than
          the Aggregate Posting Advances Outstanding as of that Computation
          Date.  If such MTM Exposure exceeds such Aggregate Posting Advances
          Outstanding, then such excess (rounded up or down to the nearest integral
          multiple of $100,000) shall be the “Posting Advance Amount” for
          that Computation Date and the related Posting Advance Date.  If such
          Aggregate Posting Advances Outstanding exceed such MTM Exposure, then such
          excess (rounded up or down to the nearest integral multiple of $100,000)
          shall
          be the “Posting Repayment Amount” for that Computation Date and
          the related Posting Repayment Date.

         

        (c)           By
          no later than 9:00 p.m. (New York time), on each Computation Date (unless
          it has

          made) or as a result of a Market Disruption Event), the Posting Calculation
          Agent shall notify the Posting Agent and the Borrower of the Posting Advance
          Amount or Posting Repayment Amount (as applicable) for such Computation
          Date,
          which shall be included in, if applicable, the Daily Notice for that date
          (and
          may be provided via email to the addresses of the Borrower and the Posting
          Agent
          set forth on Schedule 13.2).

         

        (d)           If
          the Daily Notice for any Computation Date specifies a Posting Repayment
          Amount,
          then by no later than 10:00 a.m. (New York time) on the first Business
          Day after
          such Daily Notice has been given, the Borrower may advise the Posting Agent
          that
          it has elected to repay such Posting Repayment Amount on the first Business
          Day
          following such Computation Date and such Posting Repayment Amount shall
          be due
          on such date.

         

        14.4.           Posting
          Advances Amounts

         

        .

         

        (a)           Subject
          to the terms and conditions herein set forth, each Posting Lender, severally,
          and not jointly, agrees to make a Posting Advance in Dollars on the Closing
          Date
          to the Borrower in an amount equal to such Posting Lender’s Posting Percentage
          (based on its Posting Commitment) of the Initial Posting Advance
          Amount.

         

        (b)           Subject
          to the terms and conditions herein set forth, each Posting Lender, severally,
          and not jointly, agrees to make a Posting Advance in Dollars on each Posting
          Advance Date (other than the Closing Date) to the Borrower in an amount
          equal to
          such Posting Lender’s Posting Percentage of the Posting Advance Amount for that
          Posting Advance Date.

         

        (c)           No
          later than 2:00 p.m. (New York time) on each Posting Advance Date, each
          Posting Lender will make available its Posting Percentage of each Borrowing
          of
          Posting Advances to be made on such date in the manner provided below;
          provided, further, that on the Closing Date, such funds may be
          made available at such earlier time as may be agreed among the Posting
          Lenders,
          the Borrower and the Posting Agent.

         

        (d)           Each
          Posting Lender shall make available all amounts it is to make available
          to the
          Borrower under any Borrowing of Posting Advances for its applicable Commitments
          in immediately available funds pursuant to the Payment Instructions (subject
          to
          any alternative Payment Instructions or netting and/or settlement agreements
          as
          in effect from time to time), to the Posting Agent, and the Posting Agent
          will
          apply such amounts in accordance with the Payment
          Instructions.  Unless the Posting Agent shall have been notified by
          any Posting Lender prior to the date of any such Borrowing of such Posting
          Advances that such Lender does not intend to make available to the Posting
          Agent
          such Lender’s portion of the Borrowing of such Posting Advances to be made on
          such date, the Posting Agent may assume that such Lender has made such
          amount
          available to the Posting Agent on such date of such Borrowing, and the
          Posting
          Agent, in reliance upon such assumption, may (in its sole discretion and
          without
          any obligation to do so) make available to the Borrower on such date a
          corresponding amount.  If such corresponding amount is not in fact
          made available to the Posting Agent by such Lender and the Posting Agent
          has
          made available such amount to the Borrower, the Posting Agent shall be
          entitled
          to recover such corresponding amount from such Lender.  If such Lender
          does not pay such corresponding amount forthwith upon the Posting Agent’s demand
          therefor the Posting Agent shall promptly notify the Borrower and the Borrower
          shall immediately pay such corresponding amount to the Posting Agent in
          Dollars.  The Posting Agent shall also be entitled to recover from
          such Lender or the Borrower interest on such corresponding amount in respect
          of
          each day from the date such corresponding amount was made available by
          the
          Posting Agent to the Borrower to the date such corresponding amount is
          recovered
          by the Posting Agent, at a rate per annum equal to (i) if paid by such
          Lender,
          the Overnight Rate or (ii) if paid by the Borrower, the then-applicable
          rate of
          interest or fees, calculated in accordance with Section 2.8, for the respective
          Post

         

        
          
             

          

          
            -183-

            
              

            

          

          
             

          

        

        ing
          Advances.  If such Lender shall repay to the Posting Agent such
          corresponding amount, such amount shall constitute such Lender’s portion of such
          Posting Advance for purposes of this Agreement.

         

        (e)           Nothing
          in this Section 14.4 shall be deemed to relieve any Posting Lender from
          its
          obligation to fulfill its commitments hereunder or to prejudice any rights
          that
          the Borrower may have against any Lender as a result of any default by
          such
          Lender hereunder (it being understood, however, that no Lender shall be
          responsible for the failure of any other Lender to fulfill its commitments
          hereunder).

         

        (f)           Each
          Posting Advance shall be made by the Posting Lenders pro rata in accordance
          with
          their then-applicable Posting Commitments; provided, however, that
          the failure of any Lender to make any Posting Advance shall not in itself
          relieve any other Lender of its obligation to lend hereunder (it being
          understood, however, that no Lender shall be responsible for the failure
          of any
          other Lender to make any Posting Advance required to be made by such other
          Lender).

         

        14.5.           Posting
          Repayment Amounts by the Borrower

         

        .

         

        (a)           On
          each Posting Repayment Date, the Borrower shall repay to the Posting Agent,
          for
          the benefit of the Posting Lenders an amount equal to the Posting Repayment
          Amount for that Posting Repayment Date; provided, however, that at any
          time that the Posting Lender and the Dealer are not Affiliates, the Borrower
          shall not be required to repay any Posting Repayment Amount to any Posting
          Lender while such Posting Lender is a Defaulting Lender until the earlier
          of (i)
          the 60th day
          following the date such Posting Repayment Amount is due and (ii) two Business
          Days following the date upon which such Posting Lender ceases to be a Defaulting
          Lender.

         

        (b)           On
          the Posting Facility Maturity Date, the Borrower shall repay to the Lenders
          the
          Aggregate Posting Advances Outstanding.

         

        14.6.           Payment
          Instructions; Netting and/or Settlement Agreements

         

        .

         

        (a)           From
          time to time, the Borrower may establish with the Posting Agent Payment
          Instructions regarding the making of Posting Advances hereunder.  So
          long as any such Payment Instruction remains in effect, the terms thereof
          shall
          supersede any conflicting terms set forth herein.

         

        (b)           From
          time to time, the Borrower may request that the Posting Agent, on behalf
          of the
          Posting Lenders, enter into netting and/or settlement agreements with the
          Dealer
          in order to facilitate the timely payment of amounts payable to or from
          the
          Lenders hereunder and to or from the Dealer.  So long as any such
          payment netting and/or settlement arrangement remains in effect, the terms
          thereof shall supersede any conflicting terms set forth herein.

         

        14.7.           Deemed
          Transactions

         

        .

         

        (a)           The
          “Deemed Transactions” shall consist of a portfolio of
          hypothetical over-the-counter fixed-for-floating swap transactions under
          which
          the Borrower (and its Restricted Subsidiaries) are, on a net volume basis,
          the
“floating price” payor (or has an equivalent position) and which have the net
          volumes and fixed prices and relate to the delivery periods in Columns
          I, II,
          III and IV of Schedule 1.1(e).

         

        (b)           The
          volumes subject to the Deemed Transactions may, from time to time, be subject
          to
          adjustment as follows:

         

        
          
             

          

          
            -184-

            
              

            

          

          
             

          

        

        

         

        (i)       with
          respect to the monthly volumes referenced in Column III of Schedule
          1.1(e) hereto, the Borrower may:

         

        (A)           without
          any additional fee, (x) increase the volumes in earlier periods if it
          simultaneously and permanently decreases by the same amount the volumes
          in later
          periods or (y) decrease the volume in any period without increasing the
          volume
          in any other period, and

         

        (B)           decrease
          volumes in earlier periods and simultaneously and permanently increases
          by the
          same amount the volumes in the later periods; provided that, prior to the
          effectiveness of any such simultaneous decrease in earlier volumes and
          increases
          in later volumes, the Borrower shall have paid to the Posting Lead Arranger
          and
          Bookrunner the Ad Hoc Adjustment Maintenance Fee (as defined in the Posting
          Facility Fee Letter) in respect of such change; and

         

        (ii)                  with
          respect to the monthly volumes referenced in Column II of Schedule
          1.1(e), the Borrower may reduce such volumes on a pro rata basis across all
          periods, so long as the Borrower pays to the Posting Lead Arranger and
          Bookrunner, the Partial Termination Maintenance Fee (as defined in the
          Posting
          Facility Fee Letter) for the volumes so reduced accrued through the date
          of such
          reduction; provided that, the Borrower may make no more than six volume
          adjustments in any consecutive 12 month period and no more than one volume
          adjustment during any period of 30 consecutive days.

         

        14.8.           Evidence
          of Indebtedness

         

        .

         

        (a)           Each
          Posting Lender shall maintain in accordance with its usual practice an
          account
          or accounts evidencing the Indebtedness to such Lender resulting from each
          Posting Advance made by such Lender from time to time, including the amounts
          of
          principal and interest payable and paid to such Lender from time to time
          under
          this Agreement.

         

        (b)           The
          Posting Agent shall maintain accounts in which it will record (i) the amount
          and
          date of each Posting Advance made hereunder, (ii) the amount of any principal
          or
          interest due and payable or to become due and payable from the Borrower
          to each
          Posting Lender hereunder and (iii) the amount of any sum received by the
          Posting
          Agent hereunder from the Borrower and each Lender’s share thereof.

         

        (c)           The
          entries made in the accounts maintained pursuant to clauses (a) and
(b) above shall, to the extent permitted by Applicable Law,
          be prima
          facie evidence of the existence and amounts of the obligations therein
          recorded;
provided, however, that the failure of any Lender or the Posting
          Agent to maintain such accounts or any error therein shall not in any manner
          affect the obligations of the Borrower to repay the Posting Advances Outstanding
          in accordance with their terms.

         

        14.9.           Termination
          and Reduction of Posting Commitments

         

        .

         

        (a)           The
          Posting Commitments shall terminate automatically at 5:00 p.m. (New York
          time)
          on the Posting Facility Maturity Date.

         

        (b)           Subject
          to clause (c) below, upon at least ten Business Days’ prior irrevocable
          written notice to the Posting Agent, the Borrower may at the end of any
          calendar
          month, in whole permanently terminate the Posting Commitments.  The
          Posting Agent shall advise the Posting Lenders of any notice given pursuant
          to
          this clause (b).

         

        
          
             

          

          
            -185-

            
              

            

          

          
             

          

        

        

         

        (c)           If
          the Posting Commitments terminate in whole prior to December 31, 2012 for
          any
          reason other than as a result of a Lender Default, the Borrower shall pay
          to the
          Posting Lead Arranger and Bookrunner, the Final Termination Maintenance
          Fee (as
          defined in the Posting Facility Fee Letter).

         

        (d)           The
          Borrower shall pay to the Facility Lead Arranger and Bookrunner on the
          date of
          the termination of the Posting Commitments, any Maintenance Fees accrued
          through
          the date of such termination.

         

        14.10.                      Pro
          Rata Treatment

         

        .  Each
          Posting Advance shall be allocated pro rata among the Lenders in accordance
          with
          their respective Posting Commitments (or, if such Posting Commitments shall
          have
          expired or been terminated, in accordance with the respective principal
          amounts
          of their Posting Advances Outstanding).  Each repayment of any Posting
          Advance and each payment of interest on the Posting Advances shall be allocated
          pro rata among the Lenders in accordance with their respective Posting
          Commitments (or, if such Posting Commitments shall have expired or been
          terminated, in accordance with the respective principal amounts of their
          Posting
          Advances Outstanding).  Each Lender agrees that in computing such
          Lender’s portion of any Posting Advance to be made hereunder, the Posting Agent
          may, in its discretion, round each Lender’s percentage of such Posting Advance
          to the next higher or lower whole dollar amount.

         

        14.11.                      Trading
          Acknowledgment

         

        .  The
          Borrower hereby acknowledges that, with respect to Goldman Sachs Credit
          Partners
          L.P., (i) one or more of its affiliates (“Trading Affiliates”)
          are merchants of crude oil, petroleum products, natural gas, electricity
          and
          other commodities and may, from time to time, be dealing with prospective
          counterparties, or pursuing trading or hedging strategies, in connection
          with
          aspects of such Trading Affiliates’ business that are unrelated to the Posting
          Facility and that such dealings and such trading or hedging strategies
          may be
          different from or opposite to those being pursued by, for, or in connection
          with, the Posting Facility or by or for any Credit Party or such Person’s
          account, (ii) nothing herein or in the Credit Documents shall be construed
          to
          prevent any such Trading Affiliate, or any of its partners, officers, employees
          or affiliates, in any way from purchasing, selling or otherwise trading
          in crude
          oil, petroleum products, natural gas or any other commodity for its or
          their own
          account or for the account of others, whether prior to, simultaneously
          with or
          subsequent to the term of the Posting Facility and (iii) such trading and
          hedging activities may be in conflict with or have an adverse effect on
          the
          trading or hedging activities of a Credit Party or transactions to which
          any
          Credit Party is a party (including transactions that may be referenced

                      AMENDED AND RESTATED PROMISSORY NOTE

               $1,850,000                               Dated: November 13, 2006
                                          Amended and Restated: October 25, 2007

      FOR VALUE RECEIVED, HALO Investments Ltd., a Belize international business
corporation with a registered address at Jasmine Court, 35A Regent Street, PO
Box 1777, Belize City, Belize (the "Maker"), hereby promises to pay to Averox
Inc., a Nevada corporation (the "Company"), the principal sum of One Million
Eight Hundred Fifty Thousand Dollars ($1,850,000), which will be paid in lawful
money of the United States of America, with interest thereon as set forth
herein. The principal amount outstanding under this Note and all accrued
interest thereon shall be paid in full to the Company on November 12, 2007 (the
"Maturity Date"). This Note is being delivered in connection with the
transactions contemplated by that certain Stock Purchase Agreement entered into
as of November 13, 2006 by and between the Company and the Maker and certain
other purchasers of the Company's common stock.

            1. Payment of Principal. The principal sum of $1,125,000 has
previously been paid prior to the amendment and restatement of this Note. From
the date hereof until the Maturity Date, the Maker hereby agrees to pay in the
balance of the principal sum outstanding under this Note in accordance with the
payment plan provided below:

            (i) The principal sum of $65,000 together with interest thereon as
provided in paragraph 2 shall be paid on or before the first day of each month
beginning with the month of November, 2007 up to and including the month of
August, 2008; and

            (v) The remaining principal balance of this Note together with
interest thereon as provided in paragraph 2 shall be paid on or before September
1, 2008.

            2. Interest. Interest shall accrue on the outstanding principal
amount hereof at a rate equal to the prime rate as published by The Wall Street
Journal from time to time (the "Prime Rate") plus two and a half percent (2.5%)
per annum, computed on the basis of a 360-day year and shall be payable in
arrears in full on the Maturity Date. In the event that any interest rate
provided for herein shall be determined to be unlawful, such interest rate shall
be computed at the highest rate permitted by applicable law.

            3. Voluntary Prepayments. Notwithstanding the required payments of
outstanding principal to be made in accordance with Section 1 above, Maker may
make optional prepayments of all or any portion of the then outstanding
principal and accrued, but unpaid interest under this Note, without premium or
penalty of any kind.

            4. Payments to the Company. Payments under this Note shall be made
in lawful money of the United States of America and in immediately available
funds by wire transfer or certified check as directed by the Company.

            5. Events of Default. The occurrence of any one or more of the
following events shall constitute an "Event of Default" hereunder:

                  (a) the Maker shall fail to make any payment due according to
the payment schedule set forth in Section 1 above (or upon acceleration of the
payment due under this Note pursuant to Section 5) of the outstanding principal
and accrued, but unpaid interest due and payable on this Note and such failure
shall have continued for a period of ten (10) days after written notice by the
Company to the Maker that such payment is due and unpaid;

                  (b) the Maker shall fail to make any payment due under the
terms of that certain Promissory Note dated the date hereof in the principal
amount of $650,000 of the Maker to the Company and such failure shall have
continued for a period of ten (10) days after written notice by the Company to
the Maker that such payment is due and unpaid;

                  (c) the commencement of any proceedings (i) in bankruptcy by
or against the Maker, (ii) for the dissolution, full or partial liquidation or
reorganization of the Maker, (iii) alleging that the Maker is insolvent or

<PAGE>

unable to pay its debts as they mature, or (iv) for the readjustment or
arrangement of the Maker's debts, whether under the United States Bankruptcy
Code or under any other law relating to creditors' right, whether state, federal
or foreign, now or hereafter existing for the relief of debtors, or the
commencement of any analogous statutory or non-statutory proceedings involving
the Maker; provided, however, that if such commencement of proceedings against
the Maker is involuntary, such action shall not constitute an Event of Default
unless such proceedings are not dismissed within thirty (30) days after the
commencement of such proceedings; or

                  (d)(i) the appointment of a receiver or trustee for the Maker,
or for any substantial part of the Maker's assets, (ii) a general assignment for
the benefit of creditors of the Maker, (iii) the Maker having been adjudicated
bankrupt or insolvent or (iv) the Maker filing a petition seeking to take
advantage of any other law providing for the relief of debtors. Notwithstanding
the foregoing, if such appointment or commencement of proceedings against the
Maker is involuntary, such action shall not constitute an Event of Default
unless such appointment is not revoked or such proceedings are not dismissed
within thirty (30) days after the commencement of such proceedings; or

                  (e) the entry or filing of any judgment or order in excess of
$100,000 against the Maker which remains unsatisfied or undischarged and in
effect for thirty (30) days after such entry or filing without a stay of
enforcement or execution.

            6. Remedies. If at any time an Event of Default shall have occurred,
then at the sole discretion of the Maker (i) all outstanding principal and
accrued, but unpaid interest owing under this Note shall immediately become due
and payable, together with reasonable attorneys' fees if the collection hereof
is placed in the hands of an attorney to obtain or enforce payment hereof; or
(ii) the Maker shall return to the Company such portion of the Shares that at
the time of the Event of Default had not been paid for in full.

            7. Miscellaneous.

                  (a) Binding Effect; Assignment. This Note shall be binding
upon the Maker and its successors and assigns. This Note may not be assigned by
the Maker to any Person. This Note may be assigned by the Company to any
affiliate of the Company.

                  (b) Remedies Not Waived. No course of dealing between the
Maker and the Company or any delay on the part of the Company in exercising any
rights hereunder shall operate as a waiver of any right. Any waiver by the
Company of any default under this Note shall not operate as or be construed to
be a waiver of any other default of such provision or of any default of any
other provision of this Note. All rights and remedies of the Company hereunder
are cumulative.

                  (c) Suits for Enforcement. Upon the occurrence and during the
continuation of any one or more Events of Default, the Company may proceed to
protect and enforce its rights hereunder by suit in equity, action at law or by
other appropriate proceeding, whether for the specific performance of any
covenant or agreement contained in this Note or in aid of the exercise of any
power granted in this Note, or may proceed to enforce the payment of this Note,
or to enforce any other legal or equitable right of the Company.

                  (d) Collection Costs. In case of any default under this Note,
the Maker will pay to the Company such amounts as shall be sufficient to cover
the costs and expenses of Company including reasonable attorney's fees and
expenses actually incurred due to such Event of Default.

                  (e) Amendments. This Note may not be amended except by an
instrument in writing signed by the Maker and the Company.

                  (f) Waivers. The Maker expressly waives any presentment,
demand, protest, notice of protest, or notice of any kind except as expressly
provided in this Note.

                  (g) GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE
TO PRINCIPLES OF CONFLICTS OF LAWS.

IN CONNECTION WITH THIS NOTE MAY BE BROUGHT IN A COURT OF RECORD OF THE STATE OF
