      The
        Credits

       

      SECTION
        2.01. Commitments.
        Subject
        to the terms and conditions set forth herein, each Lender agrees (a) to make
        Term Loans to the Borrower on the Effective Date in an aggregate principal
        amount not exceeding its Term Commitment and (b) to make Revolving Loans
        to the
        Borrower from time to time during the Revolving Availability Period in an
        aggregate principal amount that will not result in (x) such Lender’s Revolving
        Exposure exceeding such Lender’s Revolving Commitment or (y) the sum of the
        total Revolving Exposures exceeding the Revolving Commitments. Within the
        foregoing limits and subject to the terms and conditions set forth herein,
        the
        Borrower may borrow, prepay and reborrow Revolving Loans. Amounts repaid
        in
        respect of Term Loans may not be reborrowed.

       

      SECTION
        2.02. Loans
        and Borrowings.

       

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

       

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

       

      
        
          
          

        

        
          23

          
            

          

        

        
          
          

        

      

       

      (c)    At
        the
        commencement of each Interest Period for any Eurodollar Borrowing, such
        Borrowing shall be in an aggregate amount that is an integral multiple of
        $1,000,000 and not less than $5,000,000. At the time that each ABR Borrowing
        is
        made, such Borrowing shall be in an aggregate amount that is an integral
        multiple of $1,000,000 and not less than $1,000,000; provided
        that an
        ABR Revolving Borrowing may be in an aggregate amount that is equal to the
        entire unused balance of the total Revolving Commitments. Borrowings
        ofmore than one Type and Class may be outstanding at the same time;
        provided
        that
        there shall not at any time be more than a total of eight (8) Eurodollar
        Borrowings outstanding.

       

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

       

      SECTION
        2.03. Requests
        for Borrowings.
        To
        request a Revolving Borrowing or Term Borrowing, the Borrower shall notify
        the
        Administrative Agent of such request by telephone (a) in the case of a
        Eurodollar Borrowing, not later than 11:00 a.m., Los Angeles, California
        time,
        three Business Days before the date of the proposed Borrowing or (b) in the
        case
        of an ABR Borrowing, not later than 11:00 a.m., Los Angeles, California time,
        one Business Day before the date of the proposed Borrowing. Each such telephonic
        Borrowing Request shall be irrevocable and shall be confirmed promptly by
        hand
        delivery or telecopy to the Administrative Agent of a written Borrowing Request
        in a form approved by the Administrative Agent and signed by the Borrower.
        Each
        such telephonic and written Borrowing Request shall specify the following
        information in compliance with Section 2.02:

       

      (i)     whether
        the requested Borrowing is to be a Revolving Borrowing or a Term
        Borrowing;

       

      (ii)     the
        aggregate amount of such Borrowing;

       

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

       

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

       

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

       

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

       

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

       

      SECTION
        2.04. Funding
        of Borrowings.

       

      (a)    Each
        Lender shall make each Loan to be made by it hereunder on the proposed date
        thereof by wire transfer of immediately available funds by 10:00 a.m., Los
        Angeles, California time, to the account of the Administrative Agent most
        recently designated by it for such purpose by notice to the Lenders. The
        Administrative Agent will make such Loans

       

      
        
          
          

        

        
          24

          
            

          

        

        
          
          

        

      

       

      available
        to the Borrower by promptly crediting the amounts so received, in like funds,
        to
        an account of the Borrower designated by the Borrower in the applicable
        Borrowing Request.

       

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

       

      SECTION
        2.05. Interest
        Elections.

       

      (a)    Each
        Revolving Borrowing and Term Borrowing initially shall be of the Type specified
        in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing,
        shall have an initial Interest Period as specified in such Borrowing Request.
        Thereafter, the Borrower may elect to convert such Borrowing to a different
        Type
        or to continue such Borrowing and, in the case of a Eurodollar Borrowing,
        may
        elect Interest Periods therefor, all as provided in this Section. The Borrower
        may elect different options with respect to different portions of the affected
        Borrowing, in which case each such portion shall be allocated ratably among
        the
        Lenders holding the Loans comprising such Borrowing, and the Loans comprising
        each such portion shall be considered a separate Borrowing.

       

      (b)    To
        make
        an election pursuant to this Section, the Borrower shall notify the
        Administrative Agent of such election by telephone by the time that a Borrowing
        Request would be required under Section 2.03 if the Borrower were requesting
        a
        Borrowing of the Type resulting from such election to be made on the effective
        date of such election. Each such telephonic Interest Election Request shall
        be
        irrevocable and shall be confirmed promptly by hand delivery or telecopy
        to the
        Administrative Agent of a written Interest Election Request in a form approved
        by the Administrative Agent and signed by the Borrower.

       

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

       

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

       

      
        
          
          

        

        
          25

          
            

          

        

        
          
          

        

      

       

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

       

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

       

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

       

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

       

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

       

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

       

      SECTION
        2.06. Termination
        and Reduction of Commitments.

       

      (a)    Unless
        previously terminated, (i) the unused Term Commitments shall terminate at
        5:00
        p.m., Los Angeles, California time, on the Effective Date and (ii) the Revolving
        Commitments shall terminate on the Final Maturity Date.

       

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

       

      (c)    The
        Borrower shall notify the Administrative Agent of any election to terminate
        or
        reduce the Commitments under paragraph (b) of this Section at least three
        Business Days prior to the effective date of such termination or reduction,
        specifying such election and the effective date thereof. Promptly following
        receipt of any notice, the Administrative Agent shall advise the Lenders
        of the
        contents thereof. Each notice delivered by the Borrower pursuant to this
        Section
        shall be irrevocable; provided
        that a
        notice of termination of the Revolving Commitments delivered by the Borrower
        may
        state that such notice is conditioned upon the effectiveness of other credit
        facilities, in which case such notice may be revoked by the
        Borrower

      (by
        notice to the Administrative Agent on or prior to the specified effective
        date)
        if such condition is not satisfied. Any termination or reduction of the
        Commitments of any Class shall be permanent. Each reduction of the Commitments
        of any Class shall be made ratably among the Lenders in accordance with their
        respective Commitments of such Class.

       

      SECTION
        2.07. Repayment
        of Loans; Evidence of Debt.

       

      (a)    The
        Borrower hereby unconditionally promises to pay (i) to the Administrative
        Agent

        of
        each Revolving Loan on the Final Maturity Date; and (ii) to the Administrative
        Agent for the account of each Term Lender the then unpaid principal amount
        of
        the Term Loans of such Term Lender as provided in Section 2.08.

       

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

       

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

       

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

       

      (e)    Any
        Lender may request that Loans of any Class made by it be evidenced by a
        promissory note. In such event, the Borrower shall prepare, execute and deliver
        to such Lender a promissory note payable to the order of such Lender (or,
        if
        requested by such Lender, to such Lender and its registered assigns) and
        in a
        form approved by the Administrative Agent. Thereafter, the Loans evidenced
        by
        such promissory note and interest thereon shall at all times (including after
        assignment pursuant to Section 9.04) be represented by one or more promissory
        notes in such form payable to the order of the payee named therein (or, if
        such
        promissory note is a registered note, to such payee and its registered
        assigns).

       

      SECTION
        2.08. Amortization
        of Term Loans.

       

      (a)    Subject
        to adjustment pursuant to paragraph (c) of this Section, on each Repayment
        Date
        occurring prior to the Final Maturity Date, the Borrower shall pay to the
        Administrative Agent, for the account of the Term Lenders, a principal amount
        of
        the Term Loans in an aggregate amount equal to $1,500,000.

       

      
        
          
          

        

        
          27

          
            

          

        

        
          
          

        

      

       

      (b)    To
        the
        extent not previously paid, all Term Loans shall be due and payable on the
        Final
        Maturity Date.

       

      (c)    Any
        prepayment of a Term Borrowing shall be applied to reduce the subsequent
        scheduled repayments of Term Borrowings to be made pursuant to this Section
        ratably.

       

      SECTION
        2.09. Prepayment
        of Loans.

       

      (a)    Subject
        to prior notice in accordance with paragraph (e) of this Section, the Borrower
        shall have the right at any time and from time to time to prepay any Borrowing
        in whole or in part, without premium or penalty (subject, in the case of
        any
        prepayment of a Eurodollar Borrowing, to Section 2.14).

       

      (b)    On
        the
        date of any termination of the Revolving Commitments, the Borrower shall
        repay
        or prepay all outstanding Revolving Borrowings. If, as a result of any partial
        reduction of the Revolving Commitments, the sum of the Revolving Exposures
        would
        exceed the total Revolving Commitments after giving effect thereto, then
        the
        Borrower shall, on the date of such reduction, repay or prepay Revolving
        Borrowings in an amount equal to such excess.

       

      (c)    In
        the
        event that (i) all or a majority of the voting Capital Stock of UNS Gas or
        UNS
        Electric is sold, transferred or otherwise conveyed to any Person (other
        than a
        wholly-owned Subsidiary of UES), or (ii) all or substantially all of the
        assets
        of UNS Gas or UNS Electric are sold, transferred, leased or otherwise conveyed
        to any Person (other than a wholly-owned Subsidiary of UES), in each case
        in any
        one transaction or series of transactions, and at any time thereafter UES
        pays
        or makes a Restricted Payment in cash to the Borrower, the Borrower shall
        repay
        or prepay outstanding Borrowings (if any) in a principal amount equal to
        50% of
        each such cash Restricted Payment; provided,
        however,
        that
        (A) the Borrower shall repay or prepay in full the outstanding principal
        amount
        of the Term Loan prior to prepaying any Revolving Borrowings, and (B) the
        aggregate amount of repayments and prepayments required to be made by the
        Borrower pursuant to this paragraph (c) shall not exceed 50% of the aggregate
        net proceeds from any such transaction or transactions. The Borrower
        acknowledges and agrees that this paragraph (c) shall not constitute (1)
        a
        waiver of any Default or Event of Default that may occur if and to the extent
        that any such transaction is not permitted by the terms of this Agreement
        or any
        other Loan Document or (2) a consent by the Lenders to any such prohibited
        transaction.

       

      (d)    Prior
        to
        any optional or mandatory prepayment of Borrowings hereunder, the Borrower
        shall
        select the Borrowing or Borrowings to be prepaid and shall specify such
        selection in the notice of such prepayment pursuant to paragraph (e) of this
        Section.

       

      (e)    The
        Borrower shall notify the Administrative Agent by telephone (confirmed by
        telecopy) of any prepayment hereunder (i) in the case of prepayment of a
        Eurodollar Borrowing, not later than 11:00 a.m., Los Angeles, California
        time,
        three Business Days before the date of prepayment, or (ii) in the case of
        prepayment of an ABR Borrowing, not later than 11:00 a.m., Los Angeles,
        California time, one Business Day before the date of

      prepayment.
        Each such notice shall be irrevocable and shall specify the prepayment date
        and
        the principal amount of each Borrowing or portion thereof to be prepaid;
        provided
        that, if
        a notice of prepayment is given in connection with a conditional notice of
        termination of the Revolving Commitments as contemplated by Section 2.06,
        then
        such notice of prepayment may be revoked if such notice of termination is
        revoked in accordance with Section 2.06. Promptly following receipt of any
        such
        notice, the Administrative Agent shall advise the Lenders of the contents
        thereof. Each partial prepayment of any Borrowing shall be in an amount that
        would be permitted in the case of an advance of a Borrowing of the same Type
        as
        provided in Section 2.02. Each prepayment of a Borrowing shall be applied
        ratably to the Loans included in the prepaid Borrowing. Prepayments shall
        be
        accompanied by accrued interest to the extent required by Section 2.11 and
        any
        amounts required to be paid pursuant to Section 2.14 in connection with such
        prepayment.

       

      SECTION
        2.10. Fees.

       

      (a)    The
        Borrower agrees to pay to the Administrative Agent for the account of each
        Revolving Lender a commitment fee, which shall accrue at a rate equal to
        0.25%
per
        annum
        on the
        daily unused amount of each Revolving Commitment of such Revolving Lender
        during
        the period from and including the Effective Date to but excluding the date
        on
        which such Revolving Commitment terminates. Accrued commitment fees shall
        be
        payable quarterly in arrears on the last Business Day of March, June, September
        and December of each year and on the date on which the Revolving Commitments
        terminate. All commitment fees shall be computed on the basis of a year of
        360
        days and shall be payable for the actual number of days elapsed (including
        the
        first day but excluding the last day).

       

      (b)    The
        Borrower agrees to pay to the Administrative Agent, for its own account,
        fees
        payable in the amounts and at the times separately agreed upon by the Borrower
        and the Administrative Agent.

       

      (c)    All
        fees
        payable hereunder shall be paid on the dates due, in immediately available
        funds, to the Administrative Agent for distribution, in the case of commitment
        fees, to the Lenders entitled thereto. Fees paid shall not be refundable
        under
        any circumstances.

       

      SECTION
        2.11. Interest.

       

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

       

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

       

      (c)    Notwithstanding
        the foregoing, upon the occurrence and during the continuance of an Event
        of
        Default, (i) each ABR Loan shall bear interest at a rate of 2.0% per
        annum
        in
        excess of the rate set forth in paragraph (a) of this Section and (ii) each
        Eurodollar Loan shall bear interest at a rate of 2.0% per
        annum
        in
        excess of the rate set forth in paragraph (b) of this Section until the
        Interest Period applicable thereto shall have expired and thereafter at a
        per annum
        rate
        equal to the Alternate Base Rate plus
        the
        Applicable Rate for ABR 

       

      
        
          
          

        

        
          29

          
            

          

        

        
          
          

        

      

       

      Loans
        plus 2.0%.
        In addition, if any principal of or interest on any Loan or any fee or other
        amount payable by the Borrower hereunder is not paid when due, whether at
        stated
        maturity, upon acceleration or otherwise, such overdue amount shall bear
        interest, after as well as before judgment, at a rate per
        annum
        equal to
        (A) in the case of overdue principal of any Loan, 2.0% plus
        the rate
        otherwise applicable to such Loan as provided in the preceding paragraphs
        of
        this Section or (B) in the case of any other amount, 2.0% plus
        the rate
        applicable to ABR Loans as provided in paragraph (a) of this
        Section.

       

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

       

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

       

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

       

      (a)     the
        Administrative Agent determines (which determination shall be conclusive
        absent
        manifest error) that adequate and reasonable means do not exist for ascertaining
        the Adjusted LIBO Rate for such Interest Period; or

       

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

       

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

       

      
        
          
          

        

        
          30

          
            

          

        

        
          
          

        

      

      SECTION
        2.13. Increased
        Costs.

       

      (a)    If
        any
        Change in Law shall:

       

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

       

      (ii)     impose
        on
        any Lender, the Administrative Agent or the London interbank market any other
        condition affecting this Agreement or Eurodollar Loans made by such
        Lender;

       

      and
        the
        result of any of the foregoing shall be to increase the cost to such Lender
        of
        making or maintaining any Eurodollar Loan (or of maintaining its obligation
        to
        make any such Loan) or to reduce the amount of any sum received or receivable
        by
        such Lender or the Administrative Agent hereunder (whether of principal,
        interest or otherwise), then the Borrower will pay to such Lender or the
        Administrative Agent, as the case may be, such additional amount or amounts
        as
        will compensate such Lender or the Administrative Agent, as the case may
        be, for
        such additional costs incurred or reduction suffered.

       

      (b)    If
        any
        Lender determines that any Change in Law regarding capital requirements has
        or
        would have the effect of reducing the rate of return on such Lender’s capital or
        on the capital of such Lender’s holding company, if any, as a consequence of
        this Agreement or the Loans made by such Lender, to a level below that which
        such Lender or such Lender’s holding company could have achieved but for such
        Change in Law (taking into consideration such Lender’s policies and the policies
        of such Lender’s holding company with respect to capital adequacy), then from
        time to time the Borrower will pay to such Lender such additional amount
        or
        amounts as will compensate such Lender or such Lender’s holding company for any
        such reduction suffered.

       

      (c)    A
        certificate of a Lender setting forth the amount or amounts necessary to
        compensate such Lender or its holding company, as the case may be, as specified
        in paragraph (a) or (b) of this Section shall be delivered to the Borrower
        and
        shall be conclusive absent manifest error. The Borrower shall pay such Lender
        the amount shown as due on any such certificate within 10 days after receipt
        thereof.

       

      (d)    Failure
        or delay on the part of any Lender to demand compensation pursuant to this
        Section shall not constitute a waiver of such Lender’s right to demand such
        compensation; provided
        that the
        Borrower shall not be required to compensate a Lender pursuant to this Section
        for any increased costs or reductions incurred more than 270 days prior to
        the
        date that such Lender notifies the Borrower of the Change in Law giving rise
        to
        such increased costs or reductions and of such Lender’s intention to claim
        compensation therefor; provided further
        that, if
        the Change in Law giving rise to such increased costs or reductions is
        retroactive, then the 270-day period referred to above shall be extended
        to
        include the period of retroactive effect thereof.

      SECTION
        2.14. Break
        Funding Payments.
        In the
        event of (a) the payment of any principal of any Eurodollar Loan other than
        on
        the last day of an Interest Period applicable thereto (including as a result
        of
        an Event of Default), (b) the conversion of any Eurodollar Loan other than
        on
        the last day of the Interest Period applicable thereto, (c) the failure to
        borrow, convert, continue or prepay any Revolving Loan or Term Loan on the
        date
        specified in any notice delivered pursuant hereto (regardless of whether
        such
        notice may be revoked under Section 2.06(c) and is revoked in accordance
        therewith), or (d) the assignment of any Eurodollar Loan other than on the
        last
        day of the Interest Period applicable thereto as a result of a request by
        the
        Borrower pursuant to Section 2.17, then, in any such event, the Borrower
        shall
        compensate each Lender for the loss, cost and expense attributable to such
        event. In the case of a Eurodollar Loan, such loss, cost or expense to any
        applicable Lender shall be deemed to include an amount determined by such
        Lender
        to be the excess, if any, of (i) the amount of interest which would have
        accrued
        on the principal amount of such Loan had such event not occurred, at the
        Adjusted LIBO Rate that would have been applicable to such Loan, for the
        period
        from the date of such event to the last day of the then current Interest
        Period
        therefor (or, in the case of a failure to borrow, convert or continue, for
        the
        period that would have been the Interest Period for such Loan), over (ii)
        the
        amount of interest which would accrue on such principal amount for such period
        at the interest rate which such Lender would bid were it to bid, at the
        commencement of such period, for dollar deposits of a comparable amount and
        period from other banks in the Eurodollar market. A certificate of any Lender
        setting forth any amount or amounts that such Lender is entitled to receive
        pursuant to this Section shall be delivered to the Borrower and shall be
        conclusive absent manifest error. The Borrower shall pay such Lender the
        amount
        shown as due on any such certificate within 10 days after receipt
        thereof.

       

      SECTION
        2.15. Taxes.

       

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

       

      (b)    The
        Borrower shall indemnify the Administrative Agent and each Lender, within
        10
        days after written demand therefor, for the full amount of any Indemnified
        Taxes
        or Other Taxes paid by the Administrative 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 hereunder or under any other Loan Document (including Indemnified
        Taxes
        or Other Taxes imposed or asserted on or attributable to amounts payable
        under
        this Section) and any penalties, interest and reasonable expenses arising
        therefrom or with respect thereto, whether or not such Indemnified Taxes
        or
        Other Taxes were correctly or legally imposed or asserted by the relevant
        Governmental Authority. A certificate as to the amount of such payment or
        liability delivered to the Borrower 

       

      
        
          
          

        

        
          32

          
            

          

        

        
          
          

        

      

       

      by
        a
        Lender, or by the Administrative Agent on its own behalf or on behalf of
        a
        Lender, shall be conclusive absent manifest error.

       

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

       

      (d)    Any
        Foreign Lender shall deliver to the Borrower (with a copy to the Administrative
        Agent), at the time or times prescribed by applicable law, such properly
        completed and executed documentation prescribed by the law of the jurisdiction
        in which the Borrower is located, or by any treaty to which such jurisdiction
        is
        a party, or reasonably requested by the Borrower as will permit such payments
        to
        be made without withholding.

       

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

       

      SECTION
        2.16. Payments
        Generally; Pro
        Rata
        Treatment; Sharing of Set-offs.

       

      (a)    The
        Borrower shall make each payment required to be made by it hereunder or under
        any other Loan Document (whether of principal, interest or fees, or of amounts
        payable under Section 2.13, 2.14 or 2.15, or otherwise) prior to 10:00 a.m.,
        Los
        Angeles, California time, on the date when due, in immediately available
        funds,
        without set-off, counterclaim, recoupment or deduction of any kind. Any amounts
        received after such time on any date may, in the discretion of the
        Administrative Agent, be deemed to have been received on the next succeeding
        Business Day for purposes of calculating interest thereon. All such payments
        shall be made to the Administrative Agent at its offices located at 445 South
        Figueroa Street, Los Angeles, California 90071 (or such other office as the
        Administrative Agent shall from time to time designate to the Borrower),
        except
        that payments pursuant to Sections 2.13, 2.14, 2.15 and 9.03 shall be made
        directly to the Persons entitled thereto and payments pursuant to other Loan
        Documents shall be made to the Persons specified therein. The Administrative
        Agent shall distribute any such payments received by it for the account of
        any
        other Person to the appropriate recipient promptly following receipt thereof.
        If
        any payment hereunder or under any other Loan Document shall be due on a
        day
        that is not a Business Day, the date for payment shall be extended to the
        next
        succeeding Business Day, and, in the case of any commitments fees or any
        payment
        accruing interest, such commitment fees and such interest shall be payable
        for
        the period of such extension. All payments under each Loan Document shall
        be
        made in dollars.

       

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

       

      
        
          
          

        

        
          33

          
            

          

        

        
          
          

        

      

       

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

       

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

       

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

       

      SECTION
        2.17. Mitigation
        Obligations; Replacement of Lenders.

       

      (a)    If
        any
        Lender requests compensation under Section 2.13, or if the Borrower is required
        to pay any additional amount to any Lender or any Governmental Authority
        for the
        account of any Lender pursuant to Section 2.15, then such Lender shall use
        reasonable efforts to designate a different lending office for funding or
        booking its Loans hereunder or to assign its rights and obligations hereunder
        to
        another of its offices, branches or affiliates, if, in the judgment of such
        Lender, such designation or assignment (i) would eliminate or
        reduce

       

      
        
          
          

        

        
          34

          
            

          

        

        
          
          

        

      

       

      amounts
        payable pursuant to Section 2.13 or 2.15, as the case may be, in the future
        and
        (ii) would not subject such Lender to any unreimbursed cost or expense and
        would
        not otherwise be disadvantageous to such Lender. The Borrower hereby agrees
        to
        pay all reasonable costs and expenses incurred by any Lender in connection
        with
        any such designation or assignment.

       

      (b)    If
        (i)
        any Lender requests compensation under Section 2.13, (ii) the Borrower is
        required to pay any additional amount to any Lender or any Governmental
        Authority for the account of any Lender pursuant to Section 2.15, (iii) any
        Lender defaults in its obligation to fund Loans hereunder, or (iv) any Lender
        has not consented to a proposed amendment, waiver or modification under this
        Agreement that requires the consent of all Lenders and which has been approved
        by the Required Lenders, then the Borrower may, at its sole expense and effort,
        upon notice to such Lender and the Administrative Agent, require such Lender
        to
        assign and delegate, without recourse (in accordance with and subject to
        the
        restrictions contained in Section 9.04), all of its interests, rights and
        obligations under this Agreement to an assignee that shall assume such
        obligations (which assignee may be another Lender, if a Lender accepts such
        assignment); provided
        that (A)
        the Borrower shall have received the prior written consent of the Administrative
        Agent, which consent shall not unreasonably be withheld, (B) such Lender
        shall
        have received payment of an amount equal to the outstanding principal of
        its
        Loans, accrued interest thereon, accrued fees and all other amounts payable
        to
        it hereunder, from the assignee (to the extent of such outstanding principal
        and
        accrued interest and fees) or the Borrower (in the case of all other amounts)
        and (C) in the case of any such assignment resulting from a claim for
        compensation under Section 2.13 or payments required to be made pursuant
        to
        Section 2.15, such assignment will result in a reduction in such compensation
        or
        payments. A Lender shall not be required to make any such assignment and
        delegation if, prior thereto, as a result of a waiver by such Lender or
        otherwise, the circumstances entitling the Borrower to require such assignment
        and delegation cease to apply. 

       

      SECTION
        2.18. Illegality.
        Notwithstanding any other provision of this Agreement, if any Change in Law
        makes it unlawful, or any Governmental Authority asserts that it is unlawful,
        for any Lender to perform its obligations hereunder to make, continue or
        convert
        into Eurodollar Loans, then, on notice thereof and demand therefor by such
        Lender to the Borrower through the Administrative Agent, (a) the obligation
        of
        such Lender to make, continue or convert into Eurodollar Loans shall be
        suspended until the Administrative Agent notifies the Borrower that such
        Lender
        has determined that the circumstances causing such suspension no longer exist,
        and (b) the Borrower shall forthwith prepay in full all Eurodollar Loans
        of such
        Lender then outstanding, together with accrued and unpaid interest thereon,
        unless the Borrower, within five Business Days of such notice and demand,
        converts all Eurodollar Loans of all Lenders then outstanding into ABR Loans
        in
        accordance with the terms hereof. 

       

      SECTION
        2.19. New
        Lenders.
        On the
        Effective Date, (a) each New Revolving Lender and Increasing Revolving Lender
        shall purchase by assignment from the Existing Revolving Lenders such portion
        of
        the Revolving Loans (if any) owing to them as shall be designated by the
        Administrative Agent such that, after giving effect to all such purchases
        and
        assignments, the outstanding Revolving Loans owing to each Revolving Lender
        shall equal such Revolving Lender’s Applicable Percentage of the aggregate
        amount of Revolving Loans owing to all Revolving Lenders, and (b) after giving
        effect to the repayment of the Term Loans (as defined in the Existing Credit
        Agreement) contemplated by Section 4.01(l), each New Term

       

      
        
          
          

        

        
          35

          
            

          

        

        
          
          

        

      

       

      Lender
        and Increasing Term Lender shall purchase by assignment from the Existing
        Term
        Lenders such portion of the Term Loans owing to them as shall be designated
        by
        the Administrative Agent such that, after giving effect to all such purchases
        and assignments, the outstanding Term Loans owing to each Term Lender shall
        equal such Term Lender’s Applicable Percentage of the aggregate amount of Term
        Loans owing to all Term Lenders . 

       

      ARTICLE
        III

      Representations
        and Warranties

       

      The
        Borrower represents and warrants to the Administrative Agent and the Lenders
        that:

       

      SECTION
        3.01. Organization;
        Powers.
        The
        Borrower and each Subsidiary is duly organized, validly existing and in good
        standing under the laws of the jurisdiction of its organization, has all
        requisite corporate, partnership, limited liability company or other applicable
        organizational power and authority to carry on its business as now conducted
        and, except where the failure to do so, individually or in the aggregate,
        could
        not reasonably be expected to result in a Material Adverse Effect, is qualified
        to do business, and is in good standing, in every jurisdiction where such
        qualification is required.

       

      SECTION
        3.02. Authorization;
        Enforceability.
        The
        Transactions are within the Borrower’s corporate powers and have been duly
        authorized by all necessary corporate and, if required, stockholder action.
        This
        Agreement has been duly executed and delivered by the Borrower and constitutes,
        and each other Loan Document to which the Borrower is to be a party, when
        executed and delivered by the Borrower, will constitute, a legal, valid and
        binding obligation of the Borrower, enforceable against the Borrower in
        accordance with its terms, subject to applicable bankruptcy, insolvency,
        reorganization, moratorium or other laws affecting creditors’ rights generally
        and subject to general principles of equity, regardless of whether considered
        in
        a proceeding in equity or at law.

       

      SECTION
        3.03. Governmental
        Approvals; No Conflicts.
        The
        Transactions (a) do not require any consent or approval of, registration
        or
        filing with, or any other action by, any Governmental Authority, except such
        as
        have been obtained or made and are in full force and effect and except filings
        necessary to perfect Liens created under the Loan Documents, (b) will not
        violate any Requirement of Law, (c) will not violate or result in a default
        under any indenture, agreement or other instrument binding upon the Borrower
        or
        any Subsidiary or its assets, or give rise to a right thereunder to require
        any
        payment to be made by the Borrower or any Subsidiary, and (d) will not result
        in
        the creation or imposition of any Lien on any asset of the Borrower or any
        Subsidiary, except Liens created under the Loan Documents.

       

      SECTION
        3.04. Financial
        Condition; No Material Adverse Change.

       

      (a)    The
        audited consolidated balance sheet and related statements of income,
        stockholders’ equity and cash flows of the Borrower and the Subsidiaries for the
        fiscal year ended December 31, 2005 and the most recent financial statements
        delivered by the Borrower pursuant to Section 5.01(a) or (b) present fairly,
        in
        all material respects, the financial position and results of operations and
        cash
        flows of the Borrower and the Subsidiaries as of such dates

       

      
        
          
          

        

        
          36

          
            

          

        

        
          
          

        

      

       

      and
        for
        such periods in accordance with GAAP, subject to year-end audit adjustments
        and
        the absence of footnotes in the case of the statements delivered pursuant
        to
        Section 5.01(b). Neither the Borrower nor any Subsidiary had, at the date
        of the
        most recent balance sheet referred to above, any Guarantee, contingent liability
        or liability for taxes, or any long-term lease or unusual forward or long-term
        commitment, including any interest rate or foreign currency swap or exchange
        transaction, which, in any case, was material to the Borrower and the
        Subsidiaries, taken as a whole, and which was not reflected in the foregoing
        statements or in the notes thereto. Except as set forth on Schedule 3.04,
        during
        the period from December 31, 2005 to and including the Effective Date there
        has
        been no sale, transfer or other disposition by the Borrower or any Subsidiary
        of
        any part of its business or property, and no purchase or other acquisition
        of
        any business or property (including any Capital Stock of any other Person),
        which, in either case, is material in relation to the consolidated financial
        condition of the Borrower and the Subsidiaries taken as a whole at December
        31,
        2005.

       

      (b)    Except
        to
        the extent that any specific change is explicitly disclosed in the Disclosure
        Documents, since December 31, 2005, there has been no material adverse
        change in the financial condition, results of operations, business or prospects

        infringe upon the rights of any other Person, except for any such infringements
        that, individually or in the aggregate, could not reasonably be expected
        to
        result in a Material Adverse Effect.

      (b)    Except
        as
        explicitly disclosed in the Disclosure Documents and except with respect
        to any
        other matters that, individually or in the aggregate, could not reasonably

“margin stock” within the respective meanings of each of the quoted terms under
        Regulation U as now and from time to time hereafter in effect or for any
        purpose
        that violates the provisions of the regulations of the Board. If requested
        by
        any Lender or the Administrative Agent, the Borrower will furnish to the
        Administrative Agent and each Lender a statement to the foregoing effect
        in
        conformity with the requirements of FR Form G-3 or FR Form U-1 referred to

        Requirement of Law (other than Regulation X of the Board and Requirements
        of Law
        pertaining to utility regulation) which limits its ability to incur
        Indebtedness. 

       

      SECTION
        3.10. Taxes.
        Each of
        the Borrower and the Subsidiaries has timely filed or caused to be filed

        contested in good faith by appropriate proceedings and for which the Borrower
        or
        such Subsidiary, as applicable, has set aside on its books adequate reserves
        or
        (b) to the extent that the failure to do so could not reasonably be expected

        result in a Material Adverse Effect. 

       

      SECTION
        3.11. ERISA.
        No
        ERISA Event has occurred or is reasonably expected to occur that, when taken
        together with all other such ERISA Events for which liability is reasonably
        expected to occur, could reasonably be expected to result in a Material Adverse
        Effect. The present value of all accumulated benefit obligations under each
        Plan
        (based on the assumptions used for purposes of Statement of Financial Accounting
        Standards No. 87) did not, as of the date of the most recent financial
        statements reflecting such amounts, exceed the fair market value of the assets
        of such Plan by an amount that has resulted or could reasonably be

      expected
        to result in a Material Adverse Effect. The present value of all accumulated
        benefit obligations of all underfunded Plans (based on the assumptions used
        for
        purposes of Statement of Financial Accounting Standards No. 87) did not, as
        of the date of the most recent financial statements reflecting such amounts,
        exceed the fair market value of the assets of all such underfunded Plans
        by an
        amount that has resulted or could reasonably be expected to result in a Material
        Adverse Effect. 

       

      SECTION
        3.12. Security
        Documents.
        On the
        Effective Date, the provisions of the Security Documents are effective to
        create, in favor of the Administrative Agent for the benefit of the secured
        parties thereunder, legal, valid and enforceable Liens on or in all of the
        Collateral subject thereto, and all necessary deliveries of property to the
        Administrative Agent and all necessary and appropriate recordings and filings
        have been made in all necessary and appropriate public offices so that the
        Liens
        created by such Security Documents constitute perfected Liens on or in all
        rights, titles, estates and interests of the Borrower and any applicable
        Subsidiaries in the Collateral covered thereby, prior and superior to all
        other
        Liens, and all necessary and appropriate consents to the creation and perfection
        of such Liens have been obtained. No mortgage or financing statement or other
        instrument or recordation covering all or any part of the Collateral is on
        file
        in any recording office which has not been terminated or released, except
        as may
        have been filed in favor of the Administrative Agent. 

       

      SECTION
        3.13. Disclosure.
        The
        Borrower has disclosed to the Lenders all agreements, instruments and corporate
        or other restrictions to which it or any Subsidiary is subject, and all other
        matters known to it, that, individually or in the aggregate, could reasonably
        be
        expected to result in a Material Adverse Effect. Neither the Information
        Memorandum nor any of the other reports, financial statements, certificates
        or
        other information furnished by or on behalf of the Borrower to the
        Administrative Agent or any Lender in connection with the negotiation of
        this
        Agreement or any other Loan Document or delivered hereunder (as modified
        or
        supplemented by, and taken together with, other information so furnished)
        contains any material misstatement of a fact or omits to state any material
        fact
        necessary to make the statements therein, in the light of the circumstances
        under which they were made, not misleading; provided
        that,
        with respect to forward looking statements, the Borrower represents only
        that
        such information was prepared in good faith based upon assumptions believed
        to
        be reasonable at the time and notes that there can be no assurance that such
        expectations, beliefs or projections will be achieved or accomplished and
        that
        such projections are subject to an increasing degree of uncertainty as they
        relate to later periods of time. 

       

      SECTION
        3.14. Solvency.
        The
        Borrower is Solvent. 

       

      SECTION
        3.15. Labor
        Matters.
        There
        are no strikes or other labor disputes against the Borrower or any Subsidiary
        pending or, to the knowledge of the Borrower, threatened that (individually
        or
        in the aggregate) could reasonably be expected to have a Material Adverse
        Effect. Hours worked by and payment made to employees of the Borrower and
        the
        Subsidiaries have not been in violation of the Fair Labor Standards Act or
        any
        other applicable Requirement of Law dealing with such matters that (individually
        or in the aggregate) could reasonably be expected to have a Material Adverse
        Effect. All payments due from the Borrower or any Subsidiary on account of
        employee health and welfare insurance that (individually or in the

      aggregate)
        could reasonably be expected to have a Material Adverse Effect if not paid
        have
        been paid or accrued as a liability on the books of the Borrower or the relevant
        Subsidiary.

        Governmental Authorities respecting Environmental Laws, except to the extent
        that the same are being contested in good faith by appropriate proceedings

        become due and payable, and such failure shall continue unremedied for a
        period
        of five days; 

       

      (c)     any
        representation or warranty made or deemed made by or on behalf of the Borrower

      The
        Administrative Agent

       

      Each
        of
        the Lenders hereby irrevocably appoints the Administrative Agent as its agent
        and authorizes the Administrative Agent to take such actions on its behalf
        and
        to exercise such powers as are delegated to the Administrative Agent by the
        terms of the Loan Documents, together with such actions and powers as are
        reasonably incidental thereto. The Required Lenders or the Borrower may at
        any
        time, with the consent of the Borrower (provided
        that
        such consent shall not be required if an Event of Default under clause (a),
        (b),
        (h), (i) or (j) of Article VII shall have occurred and be continuing) or
        the
        Required Lenders, as the case may be, replace the Administrative Agent (it
        being
        understood that any such replacement Administrative Agent shall be a Person
        that
        serves as administrative agent for other credit facilities of a comparable
        size), provided
        that the
        Required Lenders or the Borrower may not replace the Administrative Agent
        unless, after giving effect to such replacement and each contemporaneous
        assignment the Required Lenders or the Borrower shall have arranged in
        connection with such replacement, (i) neither the Administrative Agent nor
        any
        of its Affiliates shall have outstanding any Loan or Commitment or other
        obligation of any kind under this Agreement or any other Loan Document and
        (ii)
        each of the Administrative Agent and its Affiliates shall have received payment
        in full of all amounts owing to it under or in respect of this Agreement
        and
        each other Loan Document. 

       

      The
        bank
        serving as the Administrative Agent hereunder shall have the same rights
        and
        powers in its capacity as a Lender as any other Lender and may exercise the
        same
        as

      though
        it
        were not the Administrative Agent, and such bank and its Affiliates may accept
        deposits from, lend money to and generally engage in any kind of business
        with
        the Borrower or any Subsidiary or other Affiliate thereof as if it were not
        the
        Administrative Agent hereunder. 

       

      The
        Administrative Agent shall not have any duties or obligations except those
        expressly set forth in the Loan Documents. Without limiting the generality
        of
        the foregoing, (a) the Administrative Agent shall not be subject to any
        fiduciary or other implied duties, regardless of whether a Default has occurred
        and is continuing, (b) the Administrative Agent shall not have any duty to
        take
        any discretionary action or exercise any discretionary powers, except
        discretionary rights and powers expressly contemplated by the Loan Documents
        that the Administrative Agent is required to exercise in writing as directed
        by
        the Required Lenders (or such other number or percentage of the Lenders as
        shall
        be necessary under the circumstances as provided in Section 9.02), and (c)
        except as expressly set forth in the Loan Documents, the Administrative Agent
        shall not have any duty to disclose, and shall not be liable for the failure
        to
        disclose, any information relating to the Borrower or any of the Subsidiaries
        that is communicated to or obtained by the bank serving as Administrative
        Agent
        or any of its Affiliates in any capacity. The Administrative Agent shall
        not be
        liable for any action taken or not taken by it with the consent or at the
        request of the Required Lenders (or such other number or percentage of the
        Lenders as shall be necessary under the circumstances as provided in Section
        9.02) or in the absence of its own gross negligence or willful misconduct.
        The
        Administrative Agent shall be deemed not to have knowledge of any Default
        unless
        and until written notice thereof is given to the Administrative Agent by
        the
        Borrower or a Lender, and the Administrative Agent shall not be responsible
        for
        or have any duty to ascertain or inquire into (i) any statement, warranty
        or
        representation made in or in connection with any Loan Document, (ii) the
        contents of any certificate, report or other document delivered hereunder
        or in
        connection with any Loan Document, (iii) the performance or observance of
        any of
        the covenants, agreements or other terms or conditions set forth in any Loan
        Document, (iv) the validity, enforceability, effectiveness or genuineness
        of any
        Loan Document or any other agreement, instrument or document, or (v) the
        satisfaction of any condition set forth in Article IV or elsewhere in any
        Loan
        Document, other than to confirm receipt of items expressly required to be
        delivered to the Administrative Agent. 

       

      Notwithstanding
        anything herein to the contrary, no Lender identified as a Co-Syndication
        Agent
        or a Co-Documentation Agent shall have any separate duties, responsibilities,
        obligations or authority as Co-Syndication Agent or Co-Documentation Agent.
        

       

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

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

       

      Subject
        to the appointment and acceptance of a successor Administrative Agent as
        provided in this paragraph, the Administrative Agent may resign at any time
        by
        notifying the Lenders and the Borrower. Upon any such resignation, the Required
        Lenders shall have the right, in consultation with the Borrower, to appoint
        a
        successor. If no successor shall have been so appointed by the Required Lenders
        and shall have accepted such appointment within 30 days after the retiring
        Administrative Agent gives notice of its resignation, then the retiring
        Administrative Agent may, on behalf of the Lenders, appoint a successor
        Administrative Agent, which shall be any commercial bank organized under
        the
        laws of the United States of America or any State thereof having a combined
        capital and surplus and undivided profits of not less than $500,000,000.
        Upon
        the acceptance of its appointment as Administrative Agent hereunder by a
        successor, such successor shall succeed to and become vested with all the
        rights, powers, privileges and duties of the retiring Administrative Agent,
        and
        the retiring Administrative Agent shall be discharged from its duties and
        obligations hereunder. The fees payable by the Borrower to a successor
        Administrative Agent shall be the same as those payable to its predecessor
        unless otherwise agreed between the Borrower and such successor. After the
        Administrative Agent’s resignation hereunder, the provisions of this Article and
        Section 9.03 shall continue in effect for the benefit of such retiring
        Administrative Agent, its sub-agents and their respective Related Parties
        in
        respect of any actions taken or omitted to be taken by any of them while
        it was
        acting as Administrative Agent. 

       

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

      SECTION
        9.02. Waivers;
        Amendments.

       

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

       

      (b)    Neither
        this Agreement nor any other Loan Document nor any provision hereof or thereof
        may be waived, amended or modified except pursuant to an agreement or agreements
        in writing entered into by the Borrower and the Required Lenders or by the
        Borrower and the Administrative Agent with the consent of the Required Lenders,
        or, in the case of any other Loan Document, pursuant to an agreement or
        agreements in writing entered into by the Administrative Agent and the Borrower,
        in each case with the consent of the Required Lenders;

       

      
        
          
          

        

        
          63

          
            

          

        

        
          
          

        

      

       

      provided
        that no such agreement shall (i) increase the Commitment of any Lender without
        the written consent of such Lender; (ii) reduce the principal amount of any
        Loan
        or reduce the rate of interest thereon, or reduce any fees payable hereunder,
        without the written consent of each Lender affected thereby; (iii) postpone
        the
        scheduled date of payment of the principal amount of any Loan, or any interest
        thereon, or reduce the amount of, waive or excuse any such payment, or postpone
        the scheduled date of expiration of any Commitment, without the written consent
        of each Lender affected thereby; (iv) change Section 2.16(b) or (c) in a
        manner
        that would alter the pro
        rata
        sharing
        of payments required thereby, without the written consent of each Lender;
        (v)
        change any of the provisions of this Section or the definition of “Required
        Lenders” or any other provision of any Loan Document specifying the number or
        percentage of Lenders (or Lenders of any Class) required to waive, amend
        or
        modify any rights hereunder or make any determination or grant any consent
        hereunder, without the written consent of each Lender (or each Lender of
        such
        Class, if applicable); (vi) change any provisions of any Loan Document in
        a
        manner that by its terms adversely affects the rights in respect of payments
        or
        Collateral of Lenders holding Loans of any Class differently from those holdings
        Loans of any other Class, without the written consent of Lenders holding
        a
        majority in interest of the outstanding Loans and unused Commitments of each
        affected Class; (vii) release all or substantially all the Collateral from
        the
        Liens of the Security Documents without the consent of each Lender; or (viii)
        amend, modify or waive any condition precedent set forth in Section 4.02
        with
        respect to the making of Loans of any Class, without the prior written consent
        of Lenders holding a majority in interest of the Commitments of such Class;
        provided further
        that (A)
        no such agreement shall amend, modify or otherwise affect the rights or duties
        of the Administrative Agent hereunder without the prior written consent of
        the
        Administrative Agent; and (B) any waiver, amendment or modification of this
        Agreement that by its terms affects the rights or duties under this Agreement
        of
        the Revolving Lenders (but not the Term Lenders) or the Term Lenders (but
        not
        the Revolving Lenders) may be effected by an agreement or agreements in writing
        entered into by the Borrower and the requisite percentage in interest of
        the
        affected Class of Lenders that would be required to consent thereto under
        this
        Section if such Class of Lenders were the only Class of Lenders hereunder
        at
        such time. In furtherance of clause (viii) of this Section 9.02(b), (x) any
        amendment or modification to or waiver of Section 6.12 or 6.13 of this Agreement
        and (y) any amendment or modification to or waiver of any provision of this
        Agreement or any other Loan Document at a time when any Default or Event
        of
        Default has occurred and is continuing that would have the effect of eliminating
        any such Default or Event of Default shall not be deemed to be effective
        for
        purposes of determining whether the conditions precedent set forth in Section
        4.02 to the making of any Loan of any Class have been satisfied unless the
        Lenders holding a majority in interest of the Commitments of such Class shall
        have consented to such amendment, modification or waiver, provided
        that the
        foregoing shall not be construed to affect any amendment or modification
        to any
        provision of this Agreement or any other Loan Document (other than any amendment
        or modification to Section 6.12 or 6.13 of this Agreement) if no Default
        or
        Event of Default has occurred and is continuing at the time of such amendment
        or
        modification. Notwithstanding the foregoing, any provision of this Agreement
        requiring the consent of a Lender unwilling to provide such consent may be
        amended by an agreement in writing entered into by the Borrower, the Required
        Lenders and the Administrative Agent if (1) by the terms of such agreement
        the
        Commitment of each such opposing Lender shall terminate upon the effectiveness
        of such amendment and (2) at the time such amendment becomes effective, each
        such opposing Lender receives payment in full of the principal of and
        interest

        Indemnity; Damage Waiver.
        

       

      (a)    The
        Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by
        the
        Administrative Agent, the Arranger and their respective Affiliates (including
        due diligence expenses and the reasonable fees, charges and disbursements
        of
        counsel for the Administrative Agent and the Arranger) in connection with
        the
        arrangement and syndication of the credit facilities provided for herein,
        the
        preparation, execution, delivery and administration of the Loan Documents
        or any

        not
        the transactions contemplated hereby or thereby shall be consummated); (ii)
        all
        out-of-pocket expenses and charges of the Arranger in connection with any

        connection with the enforcement or protection of its rights in connection
        with

        with the Loans made hereunder, including all such out-of-pocket expenses
        incurred during any workout, restructuring or negotiations in respect of
        such
        Loans. 

       

      (b)    The
        Borrower shall indemnify the Administrative Agent, the Arranger and each
        Lender,
        and each Related Party of any of the foregoing Persons (each such Person
        being
        called an “Indemnitee”),
        against, and hold each Indemnitee harmless from, any and all losses, claims,
        damages, liabilities and related expenses, including the fees, charges and
        disbursements of any counsel for any Indemnitee, incurred by or asserted

        any Subsidiary or (iv) any actual or prospective claim, litigation,
        investigation or proceeding relating to any of the foregoing, whether based
        on
        contract, tort or any other theory and regardless of whether any Indemnitee
        is a
        party thereto; provided
        that
        such indemnity shall not, as to any Indemnitee, be available to the extent
        that
        such losses, claims, damages, liabilities or related expenses are determined
        by
        a court of competent jurisdiction by final and nonappealable judgment to
        have
        resulted primarily from the gross negligence, willful misconduct or bad faith
        of
        such Indemnitee. 

       

      (c)    To
        the
        extent that the Borrower fails to pay any amount required to be paid by it

        Section, each Lender severally agrees to pay to the Administrative Agent
        or the

        of the time that the applicable unreimbursed expense or indemnity payment
        is
        sought) of such unpaid amount; provided
        that the
        unreimbursed expense or indemnified loss, claim, damage, liability or related
        expense, as the case may be, was incurred by or asserted against the
        Administrative Agent or the Arranger in its capacity as such.

      (d)    To
        the
        extent permitted by applicable law, the Borrower shall not assert, and hereby
        waives, any claim against any Indemnitee, on any theory of liability, for
        special, indirect, consequential or punitive damages (as opposed to direct
        or
        actual damages) arising out of, in connection with, or as a result of, this
        Agreement, any other Loan Document or any agreement or instrument contemplated
        hereby, the Transactions, any Loan or the use of the proceeds thereof.

        of
        the parties hereto and their respective successors and assigns permitted
        hereby,
        except that the Borrower may not assign or otherwise transfer any of its
        rights
        or obligations hereunder without the prior written consent of each Lender
        (and
        any attempted assignment or transfer by the Borrower without such consent
        shall
        be null and void). Nothing in this Agreement, expressed or implied, shall
        be
        construed to confer upon any Person (other than the parties hereto, their
        respective successors and assigns permitted hereby and, to the extent expressly
        contemplated hereby, the Related Parties of each of the Agents, the Arranger
        and
        the Lenders) any legal or equitable right, remedy or claim under or by reason
        of

      (b)    Any
        Lender may assign to one or more assignees all or a portion of its rights
        and
        obligations under this Agreement (including all or a portion of its Revolving
        Commitment, its Term Commitment and the Loans at the time owing to it);
provided
        that (i)
        except in the case of an assignment of a Term Commitment or a Term Loan to
        a
        Lender, an Affiliate of a Lender or an Approved Fund of any Lender, the
        Administrative Agent must give its prior written consent to such assignment
        (which consent shall not be unreasonably withheld), (ii) except in the case
        of
        an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of

        of
        an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of
        any
        Lender or an assignment of the entire remaining amount of the assigning Lender’s
        Commitments, the aggregate amount of the Commitments of the assigning Lender
        subject to each such assignment (determined as of the date the Assignment
        and
        Assumption with respect to such assignment is delivered to the Administrative
        Agent) shall be in an aggregate amount of not less than $5,000,000 (or
        $1,000,000 in the case of an assignment of a Term Lender’s Term Commitment or
        Term Loans) unless each of the Borrower and the Administrative Agent otherwise
        consent, (iv) each partial assignment by a Lender of its Revolving Commitment
        and Revolving Exposure or its Term Commitment and Term Loans shall be made
        as an
        assignment of a proportionate part of all the assigning Lender’s rights and
        obligations under this Agreement in respect of its Revolving Commitment and
        Revolving Exposure or its Term Commitment and Term Loans, as the case may
        be,
        (v) the parties to each assignment shall execute and deliver to the
        Administrative Agent an Assignment and Assumption, together with a processing
        and recordation fee of $3,500, and (vi) the assignee, if it shall not be
        a
        Lender, shall deliver to the Administrative Agent an Administrative
        Questionnaire; and provided further
        that any
        consent of the Borrower otherwise required under this paragraph shall not
        be
        required (A) if an Event of Default shall have occurred

      and
        be
        continuing or (B) in connection with the initial syndication of the Commitments
        and Loans. Subject to acceptance and recording thereof pursuant to paragraph
        (d)
        of this Section, from and after the effective date specified in each Assignment
        and Assumption the assignee thereunder shall be a party hereto and, to the
        extent of the interest assigned by such Assignment and Assumption, have the
        rights and obligations of a Lender under this Agreement, and the assigning
        Lender thereunder shall, to the extent of the interest assigned by such
        Assignment and Assumption, be released from its obligations under this Agreement
        (and, in the case of an Assignment and Assumption covering all of the assigning
        Lender’s rights and obligations under this Agreement, such Lender shall cease to
        be a party hereto but shall continue to be entitled to the benefits of Sections
        2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a Lender of rights
        or
        obligations under this Agreement that does not comply with this paragraph
        shall
        be treated for purposes of this Agreement as a sale by such Lender of a
        participation in such rights and obligations in accordance with paragraph
        (e) of
        this Section. 

       

      (c)    The
        Administrative Agent, acting for this purpose as an agent of the Borrower,
        shall
        maintain at one of its offices in California a copy of each Assignment and
        Assumption delivered to it and a register for the recordation of the names
        and
        addresses of the Lenders, and the Commitments of, and principal amount of
        the
        Loans owing to, each Lender pursuant to the terms hereof from time to time
        (the
“Register”).
        The
        entries in the Register shall be conclusive, and the Borrower, the
        Administrative Agent and the Lenders may treat each Person whose name is
        recorded in the Register pursuant to the terms hereof as a Lender hereunder
        for
        all purposes of this Agreement, notwithstanding notice to the contrary. The
        Register shall be available for inspection by the Borrower and any Lender
        at any
        reasonable time and from time to time upon reasonable prior notice.

       

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

       

      (e)    Any
        Lender may, without the consent of the Borrower or the Administrative Agent,
        sell participations to one or more banks or other entities (a “Participant”)
        in all
        or a portion of such Lender’s rights and obligations under this Agreement
        (including all or a portion of its Revolving Commitment, its Term Commitment
        and
        the Loans owing to it); provided
        that (i)
        such Lender’s obligations under this Agreement shall remain unchanged, (ii) such
        Lender shall remain solely responsible to the other parties hereto for the
        performance of such obligations and (iii) the Borrower, the Administrative
        Agent
        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 the Loan Documents and to approve any amendment, modification or
        waiver
        of any provision of the Loan Documents; provided
        that
        such agreement or instrument may provide that such Lender will not, without
        the
        consent of the Participant, agree to any amendment, modification or
        waiver

       

      
        
          
          

        

        
          67

          
            

          

        

        
          
          

        

      

       

      described
        in the first proviso to Section 9.02(b) that affects such Participant. Subject
        to paragraph (f) of this Section, the Borrower agrees that each Participant
        shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the
        same
        extent as if it were a Lender and had acquired its interest by assignment
        pursuant to paragraph (b) of this Section. To the extent permitted by law,
        each
        Participant also shall be entitled to the benefits of Section 9.08 as though
        it
        were a Lender, provided such Participant agrees to be subject to Section
        2.16(c)
        as though it were a Lender. 

       

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

       

      (g)    Any
        Lender may at any time pledge or assign a security interest in all or any
        portion of its rights under this Agreement to secure obligations of such
        Lender,
        including any pledge or assignment to secure obligations to a Federal Reserve
        Bank, and this Section shall not apply to any such pledge or assignment of
        a
        security interest; provided
        that no
        such pledge or assignment of a security interest shall release a Lender from
        any
        of its obligations hereunder or substitute any such pledgee or assignee for
        such
        Lender as a party hereto. In
        the
        case of any Lender that is a fund that invests in bank loans, such Lender
        may,
        without the consent of the Borrower or Administrative Agent, assign or pledge
        all or any portion of its rights under this Agreement, including the Loans
        and
        notes or any other instrument evidencing its rights as a Lender under this
        Agreement, to any holder of, trustee for, or any other representative of
        holders
        of, obligations owed or securities issued, by such fund, as security for
        such
        obligations or securities; provided
        that any
        foreclosure or similar action by such trustee or representative shall be
        subject
        to the provisions of Section 9.04(b) concerning assignments. 

       

      (h)    Notwithstanding
        anything to the contrary contained herein, any Lender (a “Granting
        Lender”)
        may
        grant to a special purpose funding vehicle (an “SPC”),
        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 to the Borrower pursuant to this Agreement; provided
        that (i)
        nothing herein shall constitute a commitment by any SPC to make any Loan
        and
        (ii) if an SPC 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 SPC 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 SPC 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 SPC, it will not institute
        against, or join any other person in instituting against, such SPC in connection
        with its activities as an SPC hereunder 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 in this Section 9.04, any SPC may
        (i)
        with notice to, but without the prior written consent of, the Borrower and
        the
        Administrative Agent and without 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 the Administrative
        Agent) providing liquidity and/or credit support to or for the account of
        such
        SPC to support the funding or maintenance of Loans and (ii) disclose on a
        confidential basis consistent with the provisions of Section 9.12 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
        SPC. The provisions of this Section relating any SPC may not be amended without
        the written consent of such SPC. 

       

      SECTION
        9.05. Survival.
        All
        covenants, agreements, representations and warranties made by the Borrower
        in
        the Loan Documents and in the certificates or other instruments delivered
        in
        connection with or pursuant to this Agreement or any other Loan Document
        shall
        be considered to have been relied upon by the other parties hereto and shall
        survive the execution and delivery of the Loan Documents and the making of
        any
        Loans, regardless of any investigation made by any such other party or on
        its
        behalf and notwithstanding that any Agent or any Lender may have had notice
        or
        knowledge of any Default or incorrect representation or warranty at the time
        any
        credit is extended hereunder, and shall continue in full force and effect
        as
        long as the principal of or any accrued interest on any Loan or any fee or
        any
        other amount payable under this Agreement is outstanding and unpaid and so
        long
        as any Commitment has not expired or terminated. The provisions of Sections
        2.13, 2.14, 2.15 and 9.03 and Article VIII shall survive and remain in full
        force and effect regardless of the consummation of the transactions contemplated
        hereby, the repayment of the Loans, the expiration or termination of the
        Commitments or the termination of this Agreement or any provision hereof.
        

       

      SECTION
        9.06. Counterparts;
        Integration; Effectiveness.
        This
        Agreement may be executed in counterparts (and by different parties hereto
        on
        different counterparts), each of which shall constitute an original, but
        all of
        which when taken together shall constitute a single contract. This Agreement,
        the other Loan Documents and any separate letter agreements with respect
        to fees
        payable to the Agents and the Arranger constitute the entire contract among
        the
        parties relating to the subject matter hereof and supersede any and all previous
        agreements and understandings, oral or written, relating to the subject matter
        hereof. Except as provided in Section 4.01, this Agreement shall become
        effective when it shall have been executed by the Administrative Agent and
        when
        the Administrative Agent shall have received counterparts hereof which, when
        taken together, bear the signatures of each of the other parties hereto,
        and
        thereafter shall be binding upon and inure to the benefit of the parties
        hereto
        and their respective successors and assigns. Delivery of an executed counterpart
        of a signature page of this Agreement by telecopy shall be effective as delivery
        of a manually executed counterpart of this Agreement. 

       

      SECTION
        9.07. Severability.
        Any
        provision of this Agreement held to be invalid, illegal or unenforceable
        in any
        jurisdiction shall, as to such jurisdiction, be ineffective to the extent
        of
        such invalidity, illegality or unenforceability without affecting the validity,
        legality and enforceability of the remaining provisions hereof, and the
        invalidity of a particular provision in a particular jurisdiction shall not
        invalidate such provision in any other jurisdiction.

      SECTION
        9.08. Right
        of Setoff.
        If an
        Event of Default shall have occurred and be continuing, each Lender and each
        of
        its Affiliates is hereby authorized at any time and from time to time, to
        the
        fullest extent permitted by law, upon any amount becoming due and payable
        by the
        Borrower hereunder (whether at the stated maturity, by acceleration or
        otherwise), to set off and apply any and all deposits (general or special,
        time
        or demand, provisional or final) at any time held and other obligations at
        any
        time owing by such Lender or Affiliate to or for the credit or the account
        of
        the Borrower against any of and all the obligations of the Borrower now or
        hereafter existing under this Agreement held by such Lender, irrespective
        of
        whether or not such Lender shall have made any demand under this Agreement
        and
        although such obligations may be unmatured. The rights of each Lender under
        this
        Section are in addition to other rights and remedies (including other rights
        of
        setoff) which such Lender may have. 

       

      SECTION
        9.09. Governing
        Law; Jurisdiction; Consent to Service of Process.
        

       

      (a)    This
        Agreement shall be construed in accordance with and governed by the law of
        the
        State of New York. 

       

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

       

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

       

      (d)    Each
        party to this Agreement irrevocably consents to service of process in the
        manner
        provided for notices in Section 9.01. Nothing in this Agreement or any other
        Loan Document will affect the right of any party to this Agreement to serve
        process in any other manner permitted by law. 

       

      SECTION
        9.10. WAIVER
        OF JURY TRIAL.
        EACH
        PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
        LAW,
        ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING

      DIRECTLY
        OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
        CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).
        EACH
        PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
        OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY
        WOULD
        NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND
        (B)
        ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
        INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
        CERTIFICATIONS IN THIS SECTION. 

       

      SECTION
        9.11. Headings.

      SECTION
        9.12. Confidentiality.
        Each of
        the Administrative Agent and the Lenders agrees to maintain the confidentiality
        of the Information (as defined below), except that Information may be disclosed
        (a) to its and its Affiliates’ directors, officers, employees and agents,
        including accountants, auditors, legal counsel and other advisors (it being
        understood that the Persons to whom such disclosure is made will be informed
        of
        the confidential nature of such Information and instructed to keep such
        Information confidential), (b) to the extent requested by any regulatory
        authority, (c) to the extent required by applicable laws or regulations or

        or
        the enforcement of rights hereunder, (f) subject to an agreement containing
        provisions substantially the same as those of this Section, to (i) any assignee
        of or Participant in, or any prospective assignee of or Participant in, any
        of
        its rights or obligations under this Agreement or (ii) any actual or prospective
        counterparty (or its advisors) to any swap or derivative transaction relating
        to
        the Borrower and its obligations, (g) with the consent of the Borrower or
        (h) to
        the extent such Information (i) becomes publicly available other than as
        a
        result of a breach of this Section or (ii) becomes available to any Agent
        or any
        Lender on a nonconfidential basis from a source other than the Borrower.
        For the
        purposes of this Section, “Information”
means
        all information received from the Borrower relating to the Borrower or its
        business, other than any such information that is available to any Agent
        or any
        Lender on a nonconfidential basis prior to disclosure by the Borrower;
provided
        that, in
        the case of information received from the Borrower after the date hereof,
        such
        information is clearly identified at the time of delivery as confidential.
        Any
        Person required to maintain the confidentiality of Information as provided
        in
        this Section shall be considered to have complied with its obligation to
        do so
        if such Person has exercised the same degree of care to maintain the
        confidentiality of such Information as such Person would accord to its own
        confidential information. 

       

      SECTION
        9.13. Interest
        Rate Limitation.
        Notwithstanding anything herein to the contrary, if at any time the interest
        rate applicable to any Loan, together with all fees, charges and other amounts
        which are treated as interest on such Loan under applicable law (collectively
        the “Charges”),
        shall
        exceed the maximum lawful rate (the “Maximum
        Rate”)
        which
        may be contracted for, charged, taken, received or reserved by the Lender
        holding such Loan in accordance with applicable law, the rate of interest
        payable in respect of such Loan hereunder,

      together
        with all Charges payable in respect thereof, shall be limited to the Maximum
        Rate and, to the extent lawful, the interest and Charges that would have
        been
        payable in respect of such Loan but were not payable as a result of the
        operation of this Section shall be cumulated and the interest and Charges
        payable to such Lender in respect of other Loans or periods shall be increased
        (but not above the Maximum Rate therefor) until such cumulated amount, together
        with interest thereon at the Federal Funds Effective Rate to the date of
        repayment, shall have been received by such Lender.

       

      SECTION
        9.14. Patriot
        Act Notice.
        Each
        Lender and each Agent (for itself and not on behalf of any other party) 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 and record information that identifies the Borrower,
        which information includes the name and address of the Borrower and other
        information that will allow such Lender or such Agent, as applicable, to
        identify the Borrower in accordance with the Patriot Act.

    This
      AMENDED AND RESTATED PLEDGE AGREEMENT, dated as of August 11, 2006 (the
“Pledge
      Agreement”),
      between UNISOURCE ENERGY CORPORATION, an Arizona corporation (the “Pledgor”

“Borrower”),
      and
      UNION BANK OF CALIFORNIA, N.A., as administrative agent (in such capacity,
      the
“Administrative
      Agent”)
      for
      the lenders (the “Lenders”)
      from
      time to time parties to the Amended and Restated Credit Agreement, dated as
      of
      August 11, 2006 (as the same may be amended, supplemented or otherwise modified

      Pledgor and the Administrative Agent previously entered into that certain Pledge
      Agreement, dated as of April 15, 2005 (as amended, supplemented or otherwise
      modified from time to time prior to the date hereof, the “Existing
      Pledge Agreement”).
      

     

    B. Pursuant
      to the Credit Agreement, the Lenders have severally agreed to make Loans and
      other extensions of credit (collectively, the “Extensions
      of Credit”)
      to the
      Borrower upon the terms and subject to the conditions set forth therein. One
      or
      more Lenders or affiliates of Lenders may from time to time enter into Hedge
      Agreements (as defined in the Credit Agreement) with the Borrower.

     

    C.     It
      is a
      condition precedent to the obligation of the Lenders to make their respective
      Extensions of Credit to the Borrower under the Credit Agreement that the Pledgor
      shall have executed and delivered this Pledge Agreement to the Administrative
      Agent for the benefit of the Lenders.

     

    D.     The
      Pledgor is the legal and beneficial owner of the shares of stock, membership
      interests, partnership interests or similar equity interests, as the case may
      be
      (such shares of stock, membership interests, partnership interests or similar
      equity interests, as the case may be, together with any shares of stock,
      membership interests, partnership interests or similar equity interests, as
      the
      case may be, described in Section 8(b), the “Pledged
      Shares”),
      described on Schedule I hereto, as such Schedule may be updated or amended
      from
      time to time, and issued by the Persons named therein, which Pledged Shares
      constitute the percentage of all the issued and outstanding shares of capital
      stock, membership interests, partnership interests or similar equity interests,
      as the case may be, of such Persons identified on such Schedule I, as such
      Schedule may be updated or amended from time to time. The Pledgor is the legal
      and beneficial owner of the Indebtedness owed to the Pledgor from any Subsidiary
      (such Indebtedness, together with any future Indebtedness at any time owed
      to
      the Pledgor from any Subsidiary, the “Pledged
      Debt”)
      described on Schedule II hereto, as such Schedule may be updated or amended
      from
      time to time.

      good

      all fees and disbursements of counsel to the Administrative Agent or to the
      Lenders that are required to be paid by the Borrower or any Subsidiary pursuant
      to the terms of the Credit Agreement or any other Loan Document) and (ii) all
      obligations and liabilities of the Borrower to any Lender or any affiliate
      of a

     as
      a whole and not to any particular provision of this Pledge Agreement, and
      Section references are to Sections of this Pledge Agreement unless otherwise

    2.     Grant
      of Security.
      The
      Pledgor hereby transfers, assigns and pledges to the Administrative Agent for
      the benefit of the Lenders, and hereby grants to the Administrative Agent for
      the benefit of the Lenders a security interest in, the following, whether now
      owned or existing or hereafter acquired or existing (collectively, the
“Collateral”):

     

    (a)     the
      Pledged Shares and the certificates representing the Pledged Shares and any
      interest of the Pledgor in the entries on the books of any financial
      intermediary pertaining to the Pledged Shares, and all dividends, cash,
      warrants, rights, instruments and other property or proceeds from time to time
      received, receivable or otherwise distributed in respect of or in exchange
      for
      any or all of the Pledged Shares;

     

    (b)     the
      Pledged Debt and the instruments evidencing the Pledged Debt, and all interest,
      cash, instruments and other property or proceeds from time to time received,
      receivable or otherwise distributed in respect of or in exchange for any or
      all
      of the Pledged Debt; and

     

    (c)     to
      the
      extent not covered by clauses (a) and (b) above, respectively, all proceeds
      of
      any or all of the foregoing Collateral. For purposes of this Pledge Agreement,
      the term “proceeds” includes whatever is receivable or received when Collateral
      or proceeds are sold, exchanged, collected or otherwise disposed of, whether
      such disposition is voluntary or involuntary, and includes, without limitation,
      proceeds of any indemnity or guaranty payable to the Pledgor or the
      Administrative Agent from time to time with respect to any of the
      Collateral.

     

    3.     Security
      for Obligations.
      This
      Pledge Agreement secures, and the Collateral is collateral security for, the
      payment of all Obligations. Without limiting the generality of the foregoing,
      this Pledge Agreement secures the payment of all amounts that constitute part
      of
      the Obligations and would be owed by the Pledgor to the Administrative Agent
      or
      the Lenders under the Loan Documents but for the fact that they are
      unenforceable or not allowable due to the existence of a bankruptcy,
      reorganization or similar proceeding involving the Pledgor.

     

    4.     Delivery
      of the Collateral.
      All
      certificates or instruments, if any, representing or evidencing the Collateral
      shall be promptly delivered to and held by or on behalf of the Administrative
      Agent pursuant hereto and shall be in suitable form for transfer by delivery,
      or
      shall be accompanied by duly executed instruments of transfer or assignment
      in
      blank, all in form and substance reasonably satisfactory to the Administrative
      Agent. The Administrative Agent shall have the right, at any time after the
      occurrence and during the continuance of an Event of Default and without notice
      to the Pledgor, to transfer to or to register in the name of the Administrative
      Agent or any of its nominees any or all of the Pledged Shares.

      and Warranties.

      all
      the issued and outstanding Capital Stock of each domestic Subsidiary directly
      owned by the Pledgor as identified on Schedule I, as such Schedule may be
      updated or amended from time to time.

     

    (b)     The
      Pledged Debt set forth on Schedule II hereto (as such Schedule may be updated
      or
      amended from time to time) represents all Indebtedness of any Subsidiary owed
      to
      the Pledgor.

     

    (c)     The
      Pledgor is the legal and beneficial owner of the Collateral, as indicated on
      Schedule I and Schedule II, as such Schedules may be updated or amended from
      time to time, pledged or assigned by the Pledgor hereunder free and clear of
      any
      Lien, except for the Lien created by this Pledge Agreement or Liens permitted
      under Section 8 hereof.

     

    (d)     As
      of the
      date of this Pledge Agreement, the Pledged Shares pledged by the Pledgor
      hereunder have been duly authorized and validly issued and are fully paid and
      non-assessable.

     

    (e)     The
      execution and delivery by the Pledgor of this Pledge Agreement and the creation
      of a security interest in the Collateral pledged by the Pledgor hereunder
      pursuant hereto create a valid and perfected first priority security interest
      in
      the Collateral, prior to any other Liens, securing the payment of the
      Obligations.

     

    (f)     The
      Pledgor has full power, authority and legal right to create a security interest
      in all the Collateral pledged by the Pledgor pursuant to this Pledge Agreement
      and will defend its and the Administrative Agent’s title or interest thereto or
      therein (and in the proceeds thereof) against any and all Liens (other than
      the
      Lien of this Pledge Agreement), however arising, or any and all Persons
      whomsoever.

     

    (g)     No
      authorization, approval or other action by, and no notice to or filing with,
      any
      Government Authority or regulatory body, other than the filing of a UCC-1
      financing statement with the Arizona Secretary of State, is required for either
      (i) the pledge by the Pledgor of the Collateral pursuant to this Pledge
      Agreement and the grant by the Pledgor of the security interest granted hereby,
      (ii) except as set forth in Section 26, the execution, delivery or performance
      of this Pledge Agreement by the Pledgor or (iii) except as set forth in Section
      26, the exercise by the Administrative Agent of the voting or other rights,
      or
      the remedies in respect of the Collateral, provided for in this Pledge Agreement
      (except as may be required in connection with a disposition of Collateral by
      laws affecting the offering and sale of securities generally).

     

    6.     Further
      Assurances.
      The
      Pledgor agrees that at any time and from time to time, at the expense of the
      Pledgor, it will promptly execute and deliver all further instruments and
      documents, and take all further action, that may be necessary, or that the
      Administrative Agent may reasonably request, in order to perfect and protect
      any
      pledge, assignment or security

     

    
      
        
        

      

      
        B-4

        
          

        

      

      
        
        

      

    

     

    interest
      granted or purported to be granted hereby or to enable the Administrative Agent
      to exercise and enforce its rights and remedies hereunder with respect to any
      Collateral. The Pledgor hereby authorizes the Administrative Agent to file
      one
      or more financing or continuation statements, and amendments thereto, relative
      to all or any part of the Collateral without the signature of the
      Pledgor.

      and

     

    (ii)     the
      Administrative Agent shall execute and deliver (or cause to be executed and

      the
      voting and other rights that it is entitled to exercise pursuant to paragraph
      (i) above.

     

    (b)     Subject

      in trust for the benefit of the Administrative Agent, be segregated from the
      other property or funds of the Pledgor and be forthwith delivered to the
      Administrative Agent as Collateral in the same form as so received (with any

      vested in the Administrative Agent, which shall thereupon have the sole right
      to
      exercise or refrain from exercising such voting and other consensual rights
      during the continuance of such Event of Default;

     

    (ii)     all
      rights of the Pledgor to receive the dividends, distributions and principal
      and
      interest payments that the Pledgor would otherwise be authorized to receive
      and
      retain pursuant to Section 7(b) shall cease, and all

     

    
      
        
        

      

      
        B-5

        
          

        

      

      
        
        

      

    

     

    such
      rights shall thereupon become vested in the Administrative Agent, which shall
      thereupon have the sole right to receive and hold as Collateral such dividends,
      distributions and principal and interest payments during the continuance of
      such
      Event of Default;

     

    (iii)     all

      to
      the Administrative Agent as Collateral in the same form as so received (with
      any
      necessary indorsements); and

     

    (iv)     in
      order
      to permit the Administrative Agent to receive all dividends, distributions
      and
      principal and interest payments to which it may be entitled under Section 7(b)
      above, to exercise the voting and other consensual rights that it may be
      entitled to exercise pursuant to Section 7(c)(i) above, and to receive all
      dividends, distributions and principal and interest payments that it may be

      written notice from the Administrative Agent, from time to time execute and
      deliver to the Administrative Agent appropriate proxies, dividend payment orders

      Agreement, provided

      the event the Pledgor sells assets or any other Collateral expressly permitted
      by the Credit Agreement and such assets are or include Collateral, the
      Administrative Agent shall release such Collateral to the Pledgor free and
      clear
      of the Lien under this Pledge Agreement concurrently with the consummation
      of
      such sale.

     

    (b)     The
      Pledgor shall (i) cause UES, UED and Millennium not to issue any stock or other

        B-6

        
          

        

      

      
        
        

      

    

     

    date
      hereof or hereafter created or acquired, and such additional shares of stock
      or
      other securities shall thereafter constitute Pledged Shares for all purposes;
      provided
      that the
      Pledgor shall not be required to pledge, and the Pledged Shares shall not
      include the Capital Stock of, any
      Subsidiary that is subject to regulation as a utility under the laws of any

      and
      (iv) pledge hereunder, immediately upon its acquisition or funding thereof,

      of the Lenders.

     

    9.     Administrative
      Agent Appointed Attorney-in-Fact.
      The
      Pledgor hereby irrevocably appoints the Administrative Agent as the Pledgor’s
      attorney-in-fact, with full authority in the place and stead of the Pledgor
      and
      in the name of the Pledgor or otherwise to take any action and to execute any
      instrument, in each case after the occurrence and during the continuance of
      an
      Event of Default, that the Administrative Agent may deem reasonably necessary
      or
      advisable to accomplish the purposes of this Pledge Agreement, including,
      without limitation, to receive, indorse and collect all instruments made payable
      to the Pledgor representing any dividend, distribution or principal or interest
      payment in respect of the Collateral or any part thereof and to give full
      discharge for the same.

     

    10.    The
      Administrative Agent’s Duties.
      The
      powers conferred on the Administrative Agent hereunder are solely to protect
      its
      interest in the Collateral and shall not impose any duty upon it to exercise
      any
      such powers. Except for the safe custody of any Collateral in its possession and
      the accounting for moneys actually received by it hereunder, the Administrative
      Agent shall have no duty as to any Collateral, as to ascertaining or taking
      action with respect to calls, conversions, exchanges, maturities, tenders or
      other matters relative to any Pledged Shares, whether or not the Administrative
      Agent or any Lender has or is deemed to have knowledge of such matters, or
      as to
      the taking of any necessary steps to preserve rights against any parties or
      any
      other rights pertaining to any Collateral. The Administrative Agent shall be
      deemed to have exercised reasonable care in the custody and preservation of
      any
      Collateral in its possession if such Collateral is accorded treatment
      substantially equal to that which the Administrative Agen accords its own
      property consisting of negotiable securities.

     

    11.   Remedies.
      If any
      Event of Default shall have occurred and be continuing, the provisions set
      forth
      below shall apply, subject to the receipt of any required regulatory approvals
      (including, without limitation, any required approvals from the ACC) with
      respect to the portion of the Collateral consisting of the common stock of
      a
      Subsidiary which owns or controls a company subject to regulation as a
      utility:

     

    (a)     The
      Administrative Agent may exercise in respect of the Collateral, in addition
      to
      other rights and remedies provided for herein or otherwise available to it,
      all
      the rights and remedies of a secured party upon default under the Uniform
      Commercial Code in effect in the State of New York at such time (the
“New
      York UCC”)
      (whether or not the New York UCC applies to the affected Collateral) and also
      may without notice except as specified below, sell the Collateral or any part
      thereof in one or more parcels at public or private sale, at any exchange
      broker’s board or at any of the Administrative Agent’s offices or elsewhere, for
      cash, on credit or for future delivery, as such time or times at such price
      or
      prices and upon such other terms as are

     

    
      
        
        

      

      
        B-7

        
          

        

      

      
        
        

      

    

     

    commercially
      reasonable irrespective of the impact of any such sales on the market price
      of
      the Collateral. Each purchaser at any such sale shall hold the property sold
      absolutely free from any claim or right on the part of the Pledgor, and the
      Pledgor hereby waives (to the extent permitted by law) all rights of redemption,
      stay and/or appraisal which it now has or may at any time in the future have
      under any rule of law or statute now existing or hereafter enacted. The Pledgor
      agrees that, to the extent notice of sale shall be required by law, at least
      ten
      days’ notice to the Pledgor of the time and place of any public sale or the time
      after which any private sale is to be made shall constitute reasonable
      notification. The Administrative Agent shall not be obligated to make any sale
      of Collateral regardless of notice of sale having been given. The Administrative
      Agent may adjourn any public or private sale from time to time by announcement
      at the time and place fixed therefor, and such sale may, without further notice,
      be made at the time and place to which it was so adjourned. To the extent
      permitted by law, the Pledgor hereby waives any claim against the Administrative
      Agent arising by reason of the fact that the price at which any Collateral
      may
      have been sold at such a private sale was less than the price that might have
      been obtained at a public sale, even if the Administrative Agent accepts the
      first offer received and does not offer such Collateral to more than one
      offeree.

     

    (b)     All
      cash
      and cash proceeds received by the Administrative Agent in respect of any sale
      of, collection from, or other realization upon, all or any part of the
      Collateral may, in the discretion of the Administrative Agent, be held by the
      Administrative Agent as collateral for, and/or then or at any time thereafter
      applied (after payment of any amounts payable to the Administrative Agent
      pursuant to Section 9.03 of the Credit Agreement) in whole or in part by the
      Administrative Agent for the benefit of the Lenders against, all or any part
      of
      the Obligations in such order as the Administrative Agent shall elect. Any
      surplus of such cash or cash proceeds held by the Administrative Agent and
      remaining after payment in full of all the Obligations shall be paid over to
      the
      Pledgor or to any other Person that may be lawfully entitled to receive such
      surplus.

     

    (c)     The
      Administrative Agent may exercise any and all rights and remedies of the Pledgor
      in respect of the Collateral.

     

    (d)     All
      payments received by the Pledgor after the occurrence and during the continuance
      of an Event of Default in respect of the Collateral shall be received in trust
      for the benefit of the Administrative Agent, shall be segregated from other
      funds of the Pledgor and shall be forthwith paid over to the Administrative
      Agent in the same form as so received (with any necessary
      indorsement).

     

    12.     Amendments,
      etc. with Respect to the Obligations; Waiver of Rights.
      The
      Pledgor shall remain obligated hereunder notwithstanding that, without any
      reservation of rights against the Pledgor and without notice to or further
      assent by the Pledgor, any demand for payment of any of the Obligations made
      by
      the Administrative Agent or any Lender may be rescinded by such party and any
      of
      the Obligations continued, and the Obligations, or the liability of any other
      party upon or for any part thereof, or any collateral security or guarantee
      therefor or right of offset with respect thereto, may, from time to time, in

     released
      by the Administrative Agent or any Lender, and the Credit Agreement, the other
      Loan Documents and any other documents executed and delivered in connection
      therewith and the Specified Hedge Agreements and any other documents executed
      and delivered in connection therewith may be amended, modified, supplemented
      or
      terminated, in whole or in part, as the Administrative Agent (or the Required
      Lenders, as the case may be, or, in the case of any Specified Hedge Agreement,
      the Lender or Lender’s affiliate party thereto) may deem advisable from time to
      time, and any collateral security, guarantee or right of offset at any time
      held

      this Pledge Agreement or any property subject thereto. When making any demand
      hereunder against the Pledgor, the Administrative Agent or any Lender may,
      but
      shall be under no obligation to, make a similar demand on any other pledgor,
      and
      any failure by the Administrative Agent or any Lender to make any such demand
      or
      to collect any payments from any other pledgor or any release of any other
      pledgor shall not relieve the Pledgor of its obligations or liabilities
      hereunder, and shall not impair or affect the rights and remedies, express
      or
      implied, or as a matter of law, of the Administrative Agent or any Lender
      against the Pledgor. For the purposes hereof, “demand” shall include the
      commencement and continuance of any legal proceedings.

     

    13.     Continuing
      Security Interest, Assignments Under the Credit Agreement.
      This
      Pledge Agreement shall create a continuing security interest in the Collateral
      and shall (a) remain in full force and effect until the payment in full in
      cash
      of the Obligations and the termination of all Commitments under the Credit
      Agreement, (b) be binding upon the Pledgor, its successors and assigns and
      (c)
      inure, together with the rights and remedies of the Administrative Agent
      hereunder, to the benefit of the Administrative Agent, the Lenders and their
      respective successors, transferees and assigns.

     

    14.     Reinstatement.
      This
      Pledge Agreement shall continue to be effective, or be reinstated, as the case
      may be, if at any time payment, or any part thereof, of any of the Obligations
      is rescinded or must otherwise be restored or returned by the Administrative
      Agent or any Lender upon the insolvency, bankruptcy, dissolution, liquidation
      or
      reorganization of the Pledgor, or upon or as a result of the appointment of
      a
      receiver, intervenor or conservator of, or trustee or similar officer for,
      the
      Pledgor or any substantial part of the property of the Pledgor, or otherwise,
      all as though such payments had not been made.

     

    15.     Notices.
      All
      notices, requests and demands pursuant hereto shall be made in accordance with
      Section 9.01 of the Credit Agreement, provided
      that any
      such notice, request or demand shall be addressed to the Pledgor at the notice

    16.     Counterparts.
      This
      Pledge Agreement may be executed by one or more of the parties on any number
      of
      separate counterparts, and all of said counterparts taken together shall be
      deemed to constitute one and the same instrument. A set of the counterparts
      of

    17.     Severability.
      Any
      provision of this Pledge 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.

     

    18.     Integration.
      This
      Pledge Agreement represents the agreement of the Pledgor with respect to the
      subject matter hereof and there are no promises or representations by the
      Administrative Agent or any Lender relative to the subject matter hereof not
      reflected herein or in the other Loan Documents.

     

    19.     Amendments
      in Writing; No Waiver; Cumulative Remedies.

     

    (a)     None
      of
      the terms or provisions of this Pledge Agreement may be waived, amended,
      supplemented or otherwise modified except by a written instrument executed
      by
      the Pledgor and the Administrative Agent in accordance with Section 9.02 of
      the
      Credit Agreement.

     

    (b)     Neither
      the Administrative Agent nor any Lender shall by any act (except by a written
      instrument pursuant to Section 19(a)), delay, indulgence, omission or otherwise
      be deemed to have waived any right or remedy hereunder or to have acquiesced
      in
      any Default or in any breach of any of the terms and conditions hereof. No
      failure to exercise, nor any delay in exercising, on the part of the
      Administrative Agent or any Lender, any right, power or privilege hereunder
      shall operate as a waiver thereof. No single or partial exercise of any right,
      power or privilege hereunder shall preclude any other or further exercise
      thereof or the exercise of any other right, power or privilege. A waiver by
      the
      Administrative Agent or any Lender of any right or remedy hereunder on any
      one
      occasion shall not be construed as a bar to any right or remedy that the
      Administrative Agent or such Lender would otherwise have on any future
      occasion.

     

    (c)     he
      rights and
      remedies herein provided are cumulative, may be exercised singly or concurrently
      and are not exclusive of any other rights or remedies provided by
      law.

     

    20.     Section
      Headings.
      The
      Section headings used in this Pledge Agreement are for convenience of reference
      only and are not to affect the construction hereof or be taken into
      consideration in the interpretation hereof.

     

    21.     Successors
      and Assigns.
      This
      Pledge Agreement shall be binding upon the successors and assigns of the Pledgor
      and shall inure to the benefit of the Administrative Agent and the Lenders
      and
      their successors and assigns; provided
      that the
      Pledgor may not assign, transfer or delegate any of its rights or obligations
      under this Pledge Agreement without the prior written consent of the
      Administrative Agent, and any such attempted assignment, transfer or delegation
      shall be null and void.

      for the Southern District of New York and appellate courts from any
      thereof;

     

    (b)     consents

      special, exemplary, punitive or consequential damages.

     

    24.     GOVERNING
      LAW.
      THIS
      PLEDGE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
      ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     

    25.     Obligations
      Absolute; Waivers and Acknowledgments; Subrogation.

     

    (a)     Obligations
      Absolute.

      actions. The liability of the Pledgor under this Agreement shall be irrevocable,
      absolute and unconditional irrespective of, and the Pledgor hereby irrevocably

      in
      respect of the Loan Documents, or any other amendment or waiver of or any
      consent to departure from any Loan Document, including, without limitation,
      any
      increase in the Obligations resulting from the extension of additional credit
      to
      the Borrower or any of the Subsidiaries or otherwise; 

     

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

     

    (iv)     any
      manner of application of Collateral or any other collateral, or proceeds
      thereof, to all or any of the Obligations, or any manner of sale or other
      disposition of any Collateral or any other collateral for all or any of the
      Obligations or any other Obligations of the Borrower under the Loan Documents
      or
      any other assets of the Borrower or any of the Subsidiaries;

     

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

     

    (vi)     any
      failure of the Administrative Agent or any Lender to disclose to the Pledgor
      any
      information relating to the business, condition (financial or otherwise),
      operations, performance or properties of the Borrower now or hereafter known
      to
      the Administrative Agent or any Lender (the Pledgor waiving any duty on the
      part
      of Administrative Agent and the Lenders to disclose such
      information);

     

    (vii)     the
      failure of any other Person to execute or deliver any other agreement or the
      release or reduction of liability of any other pledgor or any surety with
      respect to the Obligations; or

     

    (viii)     any
      other
      circumstance (including, without limitation, any statute of limitations) or
      any
      existence of or reliance on any representation by the Administrative Agent
      or
      any Lender that might otherwise constitute a defense available to, or a
      discharge of, the Pledgor or any surety.

     

    (b)     Waivers
      and Acknowledgments.

     

    (i)     The
      Pledgor hereby unconditionally and irrevocably waives promptness, diligence,

      that the Administrative Agent or any Lender protect, secure, perfect or insure
      any Lien or any property subject thereto or exhaust any right or take any action
      against any other Person or any collateral.

     

    
      
        
        

      

      
        B-12

        
          

        

      

      
        
        

      

    

     

    (ii)     The
      Pledgor hereby unconditionally and irrevocably waives any right to revoke this
      Agreement and acknowledges that this Agreement is continuing in nature and
      applies to all Obligations, whether existing now or in the future.

     

    (iii)     The
      Pledgor hereby unconditionally and irrevocably waives (x) any defense arising
      by
      reason of any claim or defense based upon an election of remedies by the
      Administrative Agent or any Lender that in any manner impairs, reduces, releases
      or otherwise adversely affects the subrogation, reimbursement, exoneration,
      contribution or indemnification rights of the Pledgor or other rights of the
      Pledgor to proceed against any guarantor or any other Person or any collateral
      and (y) any defense based on any right of set-off or counterclaim against or
      in
      respect of the obligations of the Pledgor hereunder.

     

    (iv)     The
      Pledgor acknowledges that the Administrative Agent or any Lender may, without
      notice to or demand upon the Pledgor and without affecting the liability of
      the
      Pledgor under this Agreement, foreclose under any mortgage by nonjudicial sale,
      and the Pledgor hereby waives any defense to the recovery by the Administrative
      Agent or any Lender against the Pledgor of any deficiency after such nonjudicial
      sale and any defense or benefits that may be afforded by applicable
      law.

     

    (v)     The
      Pledgor hereby unconditionally and irrevocably waives any duty on the part
      of
      the Administrative Agent or any the Lender to disclose to the Pledgor any
      matter, fact or thing relating to the business, condition (financial or
      otherwise), operations, performance, properties or prospects of the Borrower
      or
      any of the Subsidiaries now or hereafter known by the Administrative Agent
      or
      any Lender.

     

    (vi)     The
      Pledgor acknowledges that it will receive substantial direct and indirect
      benefits from the financing arrangements contemplated by the Loan Documents
      and
      that the waivers set forth in this Section 25 are knowingly made in
      contemplation of such benefits.

     

    (c)     Subrogation.
      The
      Pledgor hereby unconditionally and irrevocably agrees not to exercise any rights
      that it may now have or hereafter acquire against any insider Person that arise
      from the existence, payment, performance or enforcement of the Obligations
      under
      or in respect of this Agreement or the enforcement of the security interests
      under this Agreement, including, without limitation, any right of subrogation,
      reimbursement, exoneration, contribution or indemnification and any right to
      participate in any claim or remedy of the Administrative Agent or any Lender
      against any insider Person or any collateral, whether or not such claim, remedy
      or right arises in equity or under contract, statute or common law, including,
      without limitation, the right to take or receive from any insider Person,
      directly or indirectly, in cash or other property or by set-off or in any other
      manner, payment or security on account of such claim, remedy or right, unless
      and until all of the Obligations and all other amounts payable under this
      Agreement shall have been paid in full in cash and the Commitments shall have
      expired

     

    
      
        
        

      

      
        B-13

        
          

        

      

      
        
        

      

    

     

    or
      been
      terminated. If any amount shall be paid to the Pledgor in violation of the
      immediately preceding sentence at any time prior to the later of (i) the payment
      in full in cash of the Obligations and all other amounts payable under this
      Agreement and (ii) the Final Maturity Date, such amount shall be received and
      held in trust for the benefit of the Administrative Agent, shall be segregated
      from other property and funds of the Pledgor and shall forthwith be paid or
      delivered to the Administrative Agent in the same form as so received (with
      any
      necessary endorsement or assignment) to be credited and applied to the
      Obligations and all other amounts payable under this Agreement, whether matured
      or unmatured, in accordance with the terms of the Loan Documents, or to be
      held
      as collateral for any Obligations or other amounts payable under this Agreement
      thereafter arising. If (x) all of the Obligations and all other amounts payable
      under this Agreement shall have been paid in full in cash and (y) the Final
      Maturity Date shall have occurred, the Administrative Agent will, at the
      Pledgor’s request and expense, execute and deliver to the Pledgor appropriate
      documents, without recourse and without representation or warranty, necessary
      to
      evidence the transfer by subrogation to the Pledgor of an interest in the
      Obligations resulting from such payment made by the Pledgor pursuant to this
      Agreement.

     

    26.     Actions
      Requiring Approval.

     

    (a)     If
      an
      Event of Default shall have occurred and be continuing, the Pledgor shall take
      any action which the Administrative Agent may request in the exercise of its
      rights and remedies under this Pledge Agreement in order to transfer or assign
      the Collateral to the Administrative Agent or to such one or more third parties
      as the Administrative Agent may designate, or to a combination of the foregoing.
      The parties hereto acknowledge that, in connection with the exercise of remedies
      hereunder with respect to any portion of the Collateral consisting of the common
      stock of a Subsidiary that owns or controls a company subject to regulation
      as a
      utility, the receipt of consent or approval from certain Governmental
      Authorities (including, without limitation, the ACC) may be required. To enforce
      the provisions of this Section 26, the Administrative Agent is empowered to
      seek
      from any Governmental Authority (including, without limitation, the ACC), to
      the
      extent required, consent to or approval of any involuntary transfer of control
      of any entity whose Collateral is subject to this Pledge Agreement for the
      purpose of seeking a bona fide purchaser to whom control will ultimately be
      transferred. The Pledgor agrees to cooperate with any such purchaser and with
      the Administrative Agent in the preparation, execution and filing of any forms
      and providing any information that may be necessary or helpful in obtaining
      any
      applicable Governmental Authority’s consent to the assignment to such purchaser
      of the Collateral. The Pledgor hereby agrees to consent to any such involuntary
      transfer of control upon the request of the Administrative Agent after and
      during the continuation of an Event of Default and, without limiting any rights
      of the Administrative Agent under this Pledge Agreement, to authorize the
      Administrative Agent to nominate a trustee or receiver to assume control of
      the
      Collateral, subject only to required judicial or other consent required by
      Governmental Authorities, in order to effectuate the transactions contemplated
      in this Section 26. Such trustee or receiver shall have all the rights and
      powers as provided to it by law or court order, or to the Administrative Agent
      under this

     

    
      
        
        

      

      
        B-14

        
          

        

      

      
        
        

      

    

     

     Pledge
      Agreement. The Pledgor shall cooperate fully in obtaining the approval or
      consent of each Governmental Authority required to effectuate the
      foregoing.

     

    (b)     If
      an
      Event of Default shall have occurred and be continuing, the Pledgor shall use
      its best efforts to assist in obtaining consent or approval of any Governmental
      Authority (including, without limitation, the ACC), if required, for any action
      or transactions contemplated by this Pledge Agreement, including, without
      limitation, the preparation, execution and filing of the transferor’s or
      assignor’s portion of any application or applications for consent to the
      transfer of control or assignment necessary or appropriate under applicable
      rules and regulations for approval of the transfer or assignment of any portion
      of the Collateral.
