GUARANTY AND SURETYSHIP AGREEMENT                             (MELLON BANK LOGO)

With Power to Confess Judgement

--------------------------------------------------------------------------------

1. To induce Mellon Bank, N.A. ("Bank") to transact business and to make credit
accommodations with SUPERIOR WELL SERVICES, LTD. ("Debtor"), Undersigned, as
defined below, does hereby guarantee, absolutely and unconditionally, and does
hereby become surety for the full and timely payment of the principal of, and
interest on, all obligations, debts, dues, instruments, liabilities, advances,
judgements, damages, losses, claims, contracts, and choses in action, of
whatever nature and however arising, past, present or future, and any and all
extensions and renewals thereof in whole or in part, whether direct or indirect,
absolute or contingent, voluntary or involuntary, now due or to become due, and
whether owed to Bank from Debtor as drawer, maker, endorser, assignor,
guarantor, surety, or otherwise whatsoever ("Obligations"), except this Guaranty
and Suretyship Agreement ("Agreement") shall not extend to any obligation of
Debtor which is defined as "consumer credit" by Federal Reserve Board Regulation
Z, 12 C.F.R. Section 226.1 et seq., and is not exempted from the application of
that Regulation.  Undersigned will reimburse Bank or any subsequent holder
thereof for all expenses incurred, and not reimbursed by Debtor, in collection
of any Obligations.  If this Agreement is referred for collection to an
attorney, Undersigned will pay an attorney's fee equal to the lesser of (a) 20%
of the amount value or $500, whichever is greater, or (b) the maximum amount
permitted by law, and costs of legal proceedings.  The Undersigned's Obligations
hereunder shall be payable at Bank's offices at Pittsburgh, Pennsylvania.

2. This is a guaranty of payment and not merely of collection in the event of
any default by Debtor in payment or otherwise on any Obligations, Undersigned
will pay all or any portion of Obligations due or thereafter becoming due,
whether by acceleration or otherwise, without defalcation or offset of any kind,
without Bank first being required to make demand upon Debtor or pursue any of
its rights against Debtor, or against any other person, including other
guarantors; and without being required to liquidate or realize on any collateral
security.  In any right of action accruing to Bank, Bank may elect to proceed
against (a) Undersigned together with Debtor; (b) Undersigned and Debtor
individually; or (c) Undersigned only without having first commenced any action
against Debtor.

3. Undersigned hereby grants to Bank a security interest in, lien upon, and
right of setoff against, all deposit accounts, credits, securities, moneys or
other personal property of Undersigned which may at any time be in the
possession of, delivered to or owed by Bank, including any proceeds or returned
or unearned premiums of insurance, and the proceeds of all the foregoing
property.

4. Bank, without notice to Undersigned, may deal with Obligations and any
collateral security therefor in such manner as Bank may deem advisable and may
renew or extend Obligations or any part thereof; may accept partial payment, or
settle, release, or compromise the same; may demand additional collateral
security for Obligations, and substitute or release the same; and may compromise
or settle with or release and discharge from liability any of Undersigned or any
other guarantor of Obligations, or any other person liable to Bank for all or
part of the Obligations; all without impairing the liability of Undersigned
hereunder.

5. Undersigned hereby unconditionally waives: (a) notice of acceptance of this
Agreement by Bank and any notice of the incurring by Debtor of any Obligations;
(b) presentment for payment, notice of nonpayment, demand, protest, notice of
protest and notice of dishonor or default to any party including Undersigned;
(c) all other notices to which Undersigned may be entitled but which may legally
be waived; (d) demand for payment as a condition of liability under this
Agreement; (e) any disability of Debtor or defense available to Debtor,
including absence or cessation of Debtor's liability for any reason whatsoever;
(f) any defense or circumstance which might otherwise constitute a legal or
equitable discharge of a guarantor or surety; (g) all rights under any state or
federal statute dealing with or affecting the rights of creditors; and (h) until
Obligations are paid in full, any right to subrogation or realization on any of
Debtor's property, including participation in the marshalling of Debtor's
assets.

6. This Guaranty and Suretyship Agreement and Undersigned's payment obligations
hereunder shall continue to be effective or be reinstated, as the case may be,
if at any time payment of any of Obligations is rescinded or must otherwise be
restored or returned by Bank, all as though such payment had not been made,
Bank's good faith determination as to whether a payment must be restored or
returned shall be binding on Undersigned.

7. Until Obligations are paid in full, Undersigned hereby unconditionally
subordinates to Obligations all present and future debts, liabilities, or
obligations of Debtor to Undersigned, and all amounts due under such debts,
liabilities, or obligations shall be collected and paid over to Bank on account
of Obligations.  Undersigned, at Bank's request, shall execute a subordination
agreement in favor of Bank to further evidence and support the purpose of this
Paragraph 7.

8. Undersigned warrants to Bank: (a) no other agreement, representation or
special condition exists between Undersigned and Bank regarding the liability of
Undersigned hereunder; nor does any understanding exist between Undersigned and
Bank that the Obligations of Undersigned hereunder are or will be other that as
set out herein; and (b) as of the date hereof Undersigned has no defense
whatsoever to any action or proceeding that may be brought to enforce this
Agreement.

9. Undersigned will provide annual financial information to Bank within 120 days
of fiscal year end including balance sheets and income statements, in form and
content satisfactory to Bank and reviewed by an independent certified public
accountant not unsatisfactory to Bank.

10. No failure or delay on the part of Bank in exercising any right, power or
privilege hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of

                                                                     Page 1 of 2
<PAGE>

any right, power or privilege hereunder preclude any other or further exercise
thereof, or the exercise of any other right, power or privilege.  Failure by
Bank to insist upon strict performance hereof shall not constitute a
relinquishment of its right to demand strict performance at another time.
Receipt by Bank of any payment by any person on Obligations, with knowledge of a
default on any of Obligations of a breach of this Agreement, or both, shall not
be construed as a waiver of the default or breach.

11. THIS AGREEMENT IS A CONTINUING GUARANTY AND SHALL CONTINUE IN FORCE UNTIL
RECEIPT BY BANK OF WRITTEN NOTICE OF REVOCATION BY UNDERSIGNED OR RECEIPT OF
NOTICE OF UNDERSIGNED'S DEATH; AND IN EITHER OF SUCH EVENTS THIS AGREEMENT SHALL
CONTINUE IN EFFECT NEVERTHELESS UNTIL ALL EXISTING OBLIGATIONS OF DEBTOR TO BANK
ARE PAID; IT BEING CONTEMPLATED THAT DEBTOR MAY CREATE OR INCUR OBLIGATIONS,
REPAY AND SUBSEQUENTLY CREATE OR INCUR OBLIGATIONS WITHOUT NOTICE TO
UNDERSIGNED; AND UNDERSIGNED, BY PERMITTING THIS AGREEMENT TO REMAIN IN EFFECT,
SHALL BE BOUND.

12. This Agreement is freely assignable and transferable by Bank; however, the
duties and obligations of Undersigned may not be delegated or transferred by
Undersigned without the written consent of Bank. The rights and privileges of
Bank shall inure to the benefit of its successors and assigns, and the duties
and obligations of Undersigned shall bind Undersigned's heirs, personal
representatives, successors and assigns.

13. If any provision hereof shall for any reason be held invalid or
unenforceable, no other provision shall be affected thereby, and this Agreement
shall be construed as if the invalid or unenforceable provision had never been a
part of it.

14. As used herein, "Undersigned" refers individually and collectively to all
signers of this Agreement, including in the case of any partnership all general
partners of such partnership individually and collectively, whether or not such
partners sign below. Undersigned shall each be jointly and severally bound by
the terms hereof, and each general partner of any partnership executing this
Agreement shall be bound hereby both in such general partner's individual and
partnership capacities.

15. This Agreement shall in all respects be governed by the laws of the state
where Undersigned's Obligations hereunder are payable as set forth herein.

16. UNDERSIGNED HEREBY EMPOWERS THE PROTHONOTARY OR ANY ATTORNEY OF ANY COURT OF
RECORD TO APPEAR FOR UNDERSIGNED AND TO CONFESS JUDGMENT AS OFTEN AS NECESSARY
AGAINST UNDERSIGNED IN FAVOR OF THE HOLDER HEREOF, AS OF ANY TERM, FOR THE ABOVE
DESCRIBED OBLIGATIONS PLUS INTEREST DUE, TOGETHER WITH COSTS OF SUIT AND AN
ATTORNEY'S COMMISSION EQUAL TO THE LESSER OF (A) 20% OF ALL SUCH OBLIGATIONS OR
$500, WHICHEVER IS GREATER, OR (B) THE MAXIMUM AMOUNT PERMITTED BY LAW, WITH
RELEASE OF ALL ERRORS, UNDERSIGNED WAIVES ALL LAWS EXEMPTING REAL OR PERSONAL
PROPERTY FROM EXECUTION.

      Lender the then unpaid principal amount of each Revolving Loan made by such
      Lender to such Borrower on the Availability Termination Date for such Borrower,
      (ii) to the Agent for the account of each Lender the then unpaid principal
      amount of each Competitive Loan made by such Lender to such Borrower on the
      last
      day of the Interest Period applicable to such Loan, which shall not be later
      than the Availability Termination Date for such Borrower and (iii) to
      the
      Swingline Lender the then unpaid principal amount of each Swingline Loan made
      to
      such Borrower on the earlier of the Availability Termination Date for such
      Borrower and the fifth Business Day after such Swingline Loan is made;
provided
      that on
      each date that a Revolving Loan or Competitive Loan is made to a Borrower,
      such
      Borrower shall repay all Swingline Loans made to such Borrower and then
      outstanding. Notwithstanding the termination of the Commitments under this
      Agreement, until all of the Obligations of each Borrower (other than contingent
      indemnity obligations) shall have been fully paid and satisfied and all
      financing arrangements between each Borrower and the Lenders hereunder and
      under
      the other Loan Documents shall have been terminated, all of the rights and
      remedies with respect to such Borrower and its Obligations under this Agreement
      and the other Loan Documents shall survive.

     

    2.3.  Loans.
      Each
      Advance hereunder shall consist of (a) Revolving Loans made by the Lenders
      ratably in accordance with their Pro Rata Shares of the Aggregate Commitment,
      (b) Competitive Loans or (c) Swingline Loans.

     

    2.4.  Competitive
      Bid Procedure.
      (a)
      Subject
      to the terms and conditions set forth herein, each Borrower may request
      Competitive Bids and may (but shall not have any obligation to) accept
      Competitive Bids and borrow Competitive Loans from time to time prior to the
      Availability Termination Date for such Borrower; provided
      that
      (i) the Aggregate Outstanding Credit Exposure at any time shall not
      exceed
      the Aggregate Commitment and (ii) at no time shall the Subsidiary Credit
      Exposure of any Borrowing Subsidiary exceed the Subsidiary Sublimit of such
      Borrowing Subsidiary. Within the foregoing limits and subject to the terms
      and
      conditions set forth herein, each Borrower may, severally and not jointly with
      the other Borrowers, borrow, repay and reborrow Competitive Loans.

     

    To
      request Competitive Bids, the applicable Borrower shall notify the Agent of
      such
      request by telephone, in the case of a Eurodollar Advance, not later than 11:00
      a.m., New York time, four Business Days before the date of the proposed Advance
      and, in the case of a Fixed Rate Advance, not later than 10:00 a.m., New York
      time, one Business Day before the date of the proposed Advance; provided
      that
      each Borrower may submit up to (but not more than) two Competitive Bid Requests
      on the same day, but a Competitive Bid Request shall not be made within five
      Business Days after the date of any previous Competitive Bid Request, unless
      any
      and all such previous Competitive Bid Requests shall have been withdrawn or
      all
      Competitive Bids received in response thereto rejected. Each such telephonic
      Competitive Bid Request shall be confirmed promptly by hand delivery or telecopy
      to the Agent of a written Competitive Bid Request 

     

     

    
      
        
        

      

      
        19

        
          

        

      

      
        
        

      

    

     

    in
      a form
      approved by the Agent and signed by the applicable Borrower. Each such
      telephonic and written Competitive Bid Request shall specify the following
      information:

     

    
      	(i)  	
              the
                Borrower requesting an Advance;

            

    

     

    
      	(ii)  	
              the
                aggregate amount of the requested
                Advance;

            

    

     

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

            

    

     

    
      	(iv)  	
              whether
                such Advance is to be a Eurodollar Rate Advance or a Fixed Rate Advance;
                and

            

    

     

    
      	(v)  	
              the
                Interest Period to be applicable to such Advance, which shall be
                a period
                contemplated by the definition of the term “Interest
                Period”.

            

    

     

    Promptly
      following receipt of a Competitive Bid Request in accordance with this Section,
      the Agent shall notify the Lenders of the details thereof by telecopy, inviting
      the Lenders to submit Competitive Bids.

     

    (b)
        Each
      Lender may (but shall not have any obligation to) make one or more Competitive
      Bids to the applicable Borrower in response to a Competitive Bid Request. Each
      Competitive Bid by a Lender must be in a form approved by the Agent and must
      be
      received by the Agent by telecopy, in the case of a Eurodollar Rate Advance,
      not
      later than 10:30 a.m., New York time, three Business Days before the
      proposed date of such Advance, and in the case of a Fixed Rate Advance, not
      later than 10:30 a.m., New York time, on the proposed date of such Advance.
      Competitive Bids that do not conform substantially to the form approved by
      the
      Agent may be rejected by the Agent, and the Agent shall notify the applicable
      Lender as promptly as practicable. Each Competitive Bid shall specify
      (i) the principal amount (which shall be a minimum of $5,000,000 and
      an
      integral multiple of $1,000,000 and which may equal the entire principal amount
      of the Advance requested by such Borrower) of the Competitive Loan or Loans
      that
      the Lender is willing to make, (ii) the Competitive Bid Rate or Rates
      at
      which the Lender is prepared to make such Loan or Loans (expressed as a
      percentage rate per annum in the form of a decimal to no more than four decimal
      places) and (iii) the Interest Period applicable to each such Loan and
      the
      last day thereof.

     

    (c)
        The
      Agent
      shall promptly notify the applicable Borrower by telecopy of the Competitive
      Bid
      Rate and the principal amount specified in each Competitive Bid and the identity
      of the Lender that shall have made such Competitive Bid.

     

    (d)
        Subject
      only to the provisions of this paragraph, the applicable Borrower may accept
      or
      reject any Competitive Bid. Such Borrower shall notify the Agent by telephone,
      confirmed by telecopy in a form approved by the Agent, whether and to what
      extent it has decided to accept or reject each Competitive Bid, in the case
      of a
      Eurodollar Rate Advance, not later than 10:30 a.m., New York time, three
      Business Days before the date of the proposed Advance, and in the case of a
      Fixed Rate Advance, not later than 10:30 a.m., New York time, on the proposed
      date of the Advance; provided
      that
      (i) the failure of a Borrower to give such notice shall be deemed to
      be a
      rejection of each Competitive Bid, (ii) a Borrower shall not accept
      a
      Competitive Bid made at a particular Competitive Bid Rate if such Borrower
      rejects a 

     

     

    
      
        
        

      

      
        20

        
          

        

      

      
        
        

      

    

     

    Competitive
      Bid made at a lower Competitive Bid Rate, (iii) the aggregate amount
      of the
      Competitive Bids accepted by a Borrower shall not exceed the aggregate amount
      of
      the requested Advance specified in the related Competitive Bid Request,
      (iv) to the extent necessary to comply with clause (iii) above,
      a
      Borrower may accept Competitive Bids at the same Competitive Bid Rate in part,
      which acceptance, in the case of multiple Competitive Bids at such Competitive
      Bid Rate, shall be made pro rata in accordance with the amount of each such
      Competitive Bid, and (v) except pursuant to clause (iv) above,
      no
      Competitive Bid shall be accepted for a Competitive Loan unless such Competitive
      Loan is in a minimum principal amount of $5,000,000 and an integral multiple
      of
      $1,000,000; provided
      further
      that if
      a Competitive Loan must be in an amount less than $5,000,000 because of the
      provisions of clause (iv) above, such Competitive Loan may be for a
      minimum
      of $1,000,000 or any integral multiple thereof, and in calculating the pro
      rata
      allocation of acceptances of portions of multiple Competitive Bids at a
      particular Competitive Bid Rate pursuant to clause (iv) the amounts
      shall
      be rounded to integral multiples of $1,000,000 in a manner determined by the
      applicable Borrower. A notice given by a Borrower pursuant to this paragraph
      shall be irrevocable.

     

    (e)
        The
      Agent
      shall promptly notify each bidding Lender by telecopy whether or not its
      Competitive Bid has been accepted (and, if so, the amount and Competitive Bid
      Rate so accepted), and each successful bidder will thereupon become bound,
      subject to the terms and conditions hereof, to make the Competitive Loan in
      respect of which its Competitive Bid has been accepted.

     

    (f)
        If
      the
      Agent shall elect to submit a Competitive Bid in its capacity as a Lender,
      it
      shall submit such Competitive Bid directly to the applicable Borrower at least
      one quarter of an hour earlier than the time by which the other Lenders are
      required to submit their Competitive Bids to the Agent pursuant to
      paragraph (b) of this Section.

     

    2.5.  Swingline
      Loans.
      (a)
      Subject
      to the terms and conditions set forth herein, the Swingline Lender agrees to
      make Swingline Loans to each Borrower from time to time from and including
      the
      Closing Date and prior to the Availability Termination Date for such Borrower,
      in an amount that will not result in the Swingline Exposure exceeding
      $100,000,000; provided
      that
      (i) at no time shall the Aggregate Outstanding Credit Exposure exceed
      the
      Aggregate Commitment, (ii) at no time shall the Committed Credit Exposure of
      any
      Lender exceed its Commitment and (iii) at no time shall the Subsidiary
      Credit Exposure of any Borrowing Subsidiary exceed the Subsidiary Sublimit
      of
      such Borrowing Subsidiary; and provided further
      that the
      Swingline Lender shall not be required to make a Swingline Loan to refinance
      an
      outstanding Swingline Loan. Within the foregoing limits and subject to the
      terms
      and conditions set forth herein, each Borrower may, severally and not jointly
      with the other Borrowers, borrow, prepay and reborrow Swingline
      Loans.

     

    (b)
        Each
      Swingline Loan shall bear interest at (i) the rate per annum applicable
      to
      Floating Rate Advances or (ii) any other rate per annum (computed on
      the
      basis of the actual number of days elapsed over a year of 360 days) which shall
      be quoted by the Swingline Lender on the date such Loan is made and accepted
      by
      the applicable Borrower as provided in this Section 2.5; provided,
      that
      commencing on any date on which the Swingline Lender requires the Lenders to
      acquire participations in a Swingline Loan pursuant to Section 2.5(d),
      such
      Loan shall bear interest at the rate per annum applicable to Floating Rate
      Advances.

     

    
      
        
        

      

      
        21

        
          

        

      

      
        
        

      

    

    (c)
        To
      request a Swingline Loan, the applicable Borrower shall notify the Swingline
      Lender of such request by telephone (confirmed by telecopy), not later than
      12:00 noon, New York time, on the day of a proposed Swingline Loan. Each such
      notice shall be irrevocable and shall specify the requested date (which shall
      be
      a Business Day) and amount of the requested Swingline Loan. If so requested
      by
      the applicable Borrower, the Swingline Lender will quote an interest rate that,
      if accepted by such Borrower, will be applicable to the requested Swingline
      Loan, and such Borrower will promptly notify the Swingline Lender in the event
      it accepts such rate. The Swingline Lender will promptly advise the Agent of
      any
      such notice received from such Borrower. The Swingline Lender shall make each
      Swingline Loan available to such Borrower by means of a credit to an account
      with the Swingline Lender specified by such Borrower by 3:00 p.m., New York
      time, on the requested date of such Swingline Loan.

     

    (d)
        The
      Swingline Lender may by written notice given to the Agent not later than 10:00
      a.m., New York time, on any Business Day require the Lenders to acquire
      participations on such Business Day in all or a portion of the Swingline Loans
      outstanding. Such notice shall specify the aggregate amount of Swingline Loans
      in which Lenders will participate. Promptly upon receipt of such notice, the
      Agent will give notice thereof to each Lender, specifying in such notice such
      Lender’s Pro Rata Share of such Swingline Loan or Loans. Each Lender hereby
      absolutely and unconditionally agrees, upon receipt of notice as provided above,
      to pay to the Agent, for the account of the Swingline Lender, such Lender’s Pro
      Rata Share of such Swingline Loan or Loans. Each Lender acknowledges and agrees
      that its obligation to acquire participations in Swingline Loans pursuant to
      this paragraph is absolute and unconditional and shall not be affected by any
      circumstance whatsoever, including the occurrence and continuance of a Default
      or reduction or termination of the Commitments, and that each such payment
      shall
      be made without any offset, abatement, withholding or reduction whatsoever.
      Each
      Lender shall comply with its obligation under this paragraph by wire transfer
      of
      immediately available funds, in the same manner as provided in Section 2.11
      with
      respect to Loans made by such Lender (and Section 2.11 shall apply, mutatis
      mutandis,
      to the
      payment obligations of the Lenders), and the Agent shall promptly pay to the
      Swingline Lender the amounts so received by it from the Lenders. The Agent
      shall
      notify the Company and the applicable Borrower of any participation in any
      Swingline Loan acquired pursuant to this paragraph, and thereafter payments
      in
      respect of such Swingline Loan shall be made to the Agent and not to the
      Swingline Lender. Any amounts received by the Swingline Lender from such
      Borrower (or other party on behalf of such Borrower) in respect of a Swingline
      Loan after receipt by the Swingline Lender of the proceeds of a sale of
      participation therein shall be promptly remitted to the Agent; any such amounts
      received by the Agent shall be promptly remitted by the Agent to the Lenders
      that shall have made their payments pursuant to this paragraph and to the
      Swingline Lender, as their interests may appear. The purchase of participations
      in a Swingline Loan pursuant to this paragraph shall not relieve such Borrower
      of any default in the payment thereof.

     

    2.6.  Letters
      of Credit.

     

    (a)
        General.
      Subject
      to the terms and conditions set forth herein, (i) each Borrower may request
      the
      issuance of Letters of Credit for its own account and (ii) the Company may
      request the issuance of Letters of Credit for its own account and, jointly,
      for
      the account of any of its Subsidiaries (and in each case under this clause
      (ii),
      the Company shall be considered the 

     

    
      
        
        

      

      
        22

        
          

        

      

      
        
        

      

    

     

    sole
      Borrower under such Letter of Credit for purposes of this Agreement
      notwithstanding any listing of any Subsidiary as an account party or applicant
      with respect to such Letter of Credit), in each case in a form reasonably
      acceptable to the Agent and the applicable Issuing Bank, at any time and from
      time to time prior to the Availability Termination Date for such Borrower (with
      respect to any Letter of Credit referred to in clause (i) of this sentence)
      or
      the Company (with respect to any Letter of Credit referred to in clause (ii)
      of
      this sentence), as the case may be. In the event any Letter of Credit is issued
      for the account of a Borrowing Subsidiary under clause (ii) of the preceding
      sentence and the Company is solely liable under such Letter of Credit as
      provided in the preceding sentence, the LC Exposure related to such Letter
      of
      Credit shall not be included in the Subsidiary Credit Exposure for such
      Borrowing Subsidiary or otherwise applied or measured against the Subsidiary
      Sublimit for such Borrowing Subsidiary. In the event of any inconsistency
      between the terms and conditions of this Agreement and the terms and conditions
      of any form of letter of credit application or other agreement submitted by
      a
      Borrower to, or entered into by a Borrower with, an Issuing Bank relating to
      any
      Letter of Credit, the terms and conditions of this Agreement shall control.
      The
      Company unconditionally and irrevocably agrees that, in connection with any
      Letter of Credit referred to in clause (ii) of the first sentence of this
      paragraph, it will be fully responsible for the reimbursement of LC
      Disbursements, the payment of interest thereon and the payment of LC
      Participation Fees and other fees due under Section 2.8.2 to the same extent
      as
      if it were the sole account party in respect of such Letter of Credit (the
      Company hereby irrevocably waiving any defenses that might otherwise be
      available to it as a guarantor of the obligations of any Subsidiary that shall
      be a joint account party in respect of any such Letter of Credit).

     

    (b)
        Notice
      of Issuance, Amendment, Renewal, Extension; Certain Conditions.
      To
      request the issuance of a Letter of Credit (or the amendment, renewal or
      extension of an outstanding Letter of Credit), the applicable Borrower shall
      hand deliver or telecopy (or transmit by electronic communication, if
      arrangements for doing so have been approved by the applicable Issuing Bank)
      to
      the applicable Issuing Bank and the Agent (reasonably in advance of the
      requested date of issuance, amendment, renewal or extension) a notice requesting
      the issuance of a Letter of Credit, or identifying the Letter of Credit to
      be
      amended, renewed or extended, and specifying the date of issuance, amendment,
      renewal or extension (which shall be a Business Day), the date on which such
      Letter of Credit is to expire (which shall comply with paragraph (c)
      of
      this Section), the amount of such Letter of Credit, the account party or account
      parties with respect to such Letter of Credit, the name and address of the
      beneficiary thereof and such other information as shall be necessary to prepare,
      amend, renew or extend such Letter of Credit. If requested by the applicable
      Issuing Bank, such Borrower also shall submit a letter of credit application
      on
      such Issuing Bank’s standard form in connection with any request for a Letter of
      Credit. A Letter of Credit shall be issued, amended, renewed or extended only
      if
      (and upon issuance, amendment, renewal or extension of each Letter of Credit,
      such Borrower shall be deemed to represent and warrant that), after giving
      effect to such issuance, amendment, renewal or extension (i) the Aggregate
      Outstanding Credit Exposure will not exceed the Aggregate Commitment, (ii)
      the
      Committed Credit Exposure of any Lender will not exceed its Commitment,
      (iii) the Subsidiary Credit Exposure of any Borrowing Subsidiary will
      not
      exceed the Subsidiary Sublimit of such Borrowing Subsidiary, (iv) the portion
      of
      the LC Exposure attributable to Letters of Credit issued by the applicable
      Issuing Bank will not exceed the LC Commitment of such Issuing Bank and (v)
      if
      the Commitment Termination Date shall have been extended pursuant to Section
      2.23(a) with respect to some of but not all the Lenders, the 

     

    
      
        
        

      

      
        23

        
          

        

      

      
        
        

      

    

     

    portion
      of the LC Exposure attributable to Letters of Credit with expiry dates after
      the
      Existing Commitment Termination Date (as defined in Section 2.23(a)) will not
      exceed the portion of the Aggregate Commitment attributable to the Commitments
      of the Consenting Lenders (as defined in Section 2.23(a)). If the Required
      Lenders notify the Issuing Banks that a Default exists and instruct the Issuing
      Banks to suspend the issuance, amendment, renewal or extension of Letters of
      Credit, no Issuing Bank shall issue, amend, renew or extend any Letter of Credit
      without the consent of the Required Lenders until such notice is withdrawn
      by
      the Required Lenders (and each Lender that shall have delivered such notice
      agrees promptly to withdraw it at such time as no Default exists).

     

    (c)
        Expiration
      Date.
      Each
      Letter of Credit shall expire at or prior to the close of business on the
      earlier of (i) the date one year after the date of the issuance of such
      Letter of Credit (or, in the case of any renewal or extension thereof, one
      year
      after such renewal or extension) and (ii) the date that is five Business
      Days prior to the Availability Termination Date for the applicable
      Borrower.

     

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

     

    (e)
        Reimbursement.
      If an
      Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit,
      the applicable Borrower shall reimburse such LC Disbursement by paying to the
      Agent an amount equal to such LC Disbursement not later than 12:00 noon, New
      York City time, on the date that such LC Disbursement is made, if such Borrower
      shall have received notice of such LC Disbursement prior to 10:00 a.m., New
      York
      City time, on such date, or, if such notice has not been received by such
      Borrower prior to such time on such date, then not later than 12:00 noon, New
      York City time, on (i) the Business Day that such Borrower receives
      such
      notice, if such notice is received prior to 10:00 a.m., New York City time,
      on
      the day of receipt, or (ii) the Business Day immediately following the
      day
      that such Borrower receives such notice, if such notice is not received prior
      to
      such time on the day of receipt; provided
      that, if
      such LC Disbursement is not less than $1,000,000, such Borrower may, subject
      to
      the conditions to borrowing set forth herein, request in accordance with Section
      2.1 or 2.5 that such payment be financed with a Floating Rate Advance or
      Swingline Loan in an equivalent amount and, to the extent so financed, such
      Borrower’s obligation to make such

     

    
      
        
        

      

      
        24

        
          

        

      

      
        
        

      

    

     

    payment
      shall be discharged and replaced by the resulting Floating Rate Advance or
      Swingline Loan. If such Borrower fails to make such payment when due, the Agent
      shall notify each Lender of the applicable LC Disbursement, the payment then
      due
      from such Borrower in respect thereof and such Lender’s Pro Rata Share thereof.
      Promptly following receipt of such notice, each Lender shall pay to the Agent
      its Pro Rata Share of the payment then due from such Borrower, in the same
      manner as provided in Section 2.11 with respect to Loans made by such
      Lender (and Section 2.11 shall apply, mutatis mutandis,
      to the
      payment obligations of the Lenders), and the Agent shall promptly pay to such
      Issuing Bank the amounts so received by it from the Lenders. Promptly following
      receipt by the Agent of any payment from such Borrower pursuant to this
      paragraph, the Agent shall distribute such payment to such Issuing Bank or,
      to
      the extent that Lenders have made payments pursuant to this paragraph to
      reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as
      their
      interests may appear. Any payment made by a Lender pursuant to this paragraph
      to
      reimburse an Issuing Bank for any LC Disbursement (other than the funding of
      a
      Floating Rate Advance or a Swingline Loan as contemplated above) shall not
      constitute a Loan and shall not relieve such Borrower of its obligation to
      reimburse such LC Disbursement.

     

    (f)
        Obligations
      Absolute.
      Each
      Borrower’s obligation to reimburse LC Disbursements as provided in
      paragraph (e) of this Section shall be several, shall be absolute,
      unconditional and irrevocable, and shall be performed strictly in accordance
      with the terms of this Agreement under any and all circumstances whatsoever
      and
      irrespective of (i) any lack of validity or enforceability of any Letter
      of
      Credit or this Agreement, or any term or provision therein, (ii) any
      draft
      or other document presented under a Letter of Credit proving to be forged,
      fraudulent or invalid in any respect or any statement therein being untrue
      or
      inaccurate in any respect, (iii) payment by an Issuing Bank under a
      Letter
      of Credit against presentation of a draft or other document that does not comply
      with the terms of such Letter of Credit, or (iv) any other event or
      circumstance whatsoever, whether or not similar to any of the foregoing, that
      might, but for the provisions of this Section, constitute a legal or equitable
      discharge of, or provide a right of setoff against, such Borrower’s obligations
      hereunder. None of the Agent, the Lenders or the Issuing Banks, or any of their
      respective affiliates, directors, officers or employees, shall have any
      liability or responsibility by reason of or in connection with the issuance
      or
      transfer of any Letter of Credit or any payment or failure to make any payment
      thereunder (irrespective of any of the circumstances referred to in the
      preceding sentence), or any error, omission, interruption, loss or delay in
      transmission or delivery of any draft, notice or other communication under
      or
      relating to any Letter of Credit (including any document required to make a
      drawing thereunder), any error in interpretation of technical terms or any
      consequence arising from causes beyond the control of the applicable Issuing
      Bank; provided
      that the
      foregoing shall not be construed to excuse an Issuing Bank from liability to
      a
      Borrower to the extent of any direct damages (as opposed to consequential
      damages, claims in respect of which are hereby waived by each Borrower to the
      extent permitted by applicable law) suffered by such Borrower that are caused
      by
      such Issuing Bank’s failure to exercise care when determining whether drafts and
      other documents presented under a Letter of Credit comply with the terms
      thereof. The parties hereto expressly agree that, in the absence of gross
      negligence or willful misconduct on the part of an Issuing Bank (as finally
      determined by a court of competent jurisdiction), an Issuing Bank shall be
      deemed to have exercised care in each such determination. In furtherance of
      the
      foregoing and without limiting the generality thereof and subject to any
      non-waivable provisions of the laws and/or other rules to which a Letter of
      Credit 

     

    
      
        
        

      

      
        25

        
          

        

      

      
        
        

      

    

     

    is
      subject, the parties agree that, with respect to documents presented which
      appear on their face to be in substantial compliance with the terms of a Letter
      of Credit, an Issuing Bank may, in its sole discretion, either accept and make
      payment upon such documents without responsibility for further investigation,
      regardless of any notice or information to the contrary, or refuse to accept
      and
      make payment upon such documents if such documents are not in strict compliance
      with the terms of such Letter of Credit.

     

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

     

    (h)
        Interim
      Interest.
      If an
      Issuing Bank shall make any LC Disbursement, then, unless the applicable
      Borrower shall reimburse such LC Disbursement in full on the date such LC
      Disbursement is made, the unpaid amount thereof shall bear interest, for each
      day from and including the date such LC Disbursement is made to but excluding
      the date that such Borrower reimburses such LC Disbursement, at the rate per
      annum then applicable to Floating Rate Advances; provided
      that, if
      such Borrower fails to reimburse such LC Disbursement when due pursuant to
      paragraph (e) of this Section, then Section 2.14 shall apply.
      Interest
      accrued pursuant to this paragraph shall be for the account of such Issuing
      Bank, except that interest accrued on and after the date of payment by any
      Lender pursuant to paragraph (e) of this Section to reimburse such Issuing
      Bank shall be for the account of such Lender to the extent of such
      payment.

     

    (i)
        Cash
      Collateralization.
      If any
      Default with respect to a Borrower shall occur and be continuing, on the
      Business Day that such Borrower receives notice from the Agent or the Required
      Lenders (or, if the maturity of the Loans has been accelerated, Lenders with
      LC
      Exposures representing greater than 50% of the total LC Exposure) demanding
      the
      deposit of cash collateral pursuant to this paragraph, such Borrower shall
      deposit in an account with the Agent, in the name of the Agent and for the
      benefit of the Lenders, an amount in cash equal to the portion of the LC
      Exposure as of such date attributable to Letters of Credit issued for the
      account of such Borrower, plus any accrued and unpaid interest thereon;
provided
      that the
      obligation to deposit such cash collateral shall become effective immediately,
      and such deposit shall become immediately due and payable, without demand or
      other notice of any kind, upon the occurrence of any Default with respect to
      such Borrower described in Sections 7.6 or 7.7. Such deposit shall be
      held
      by the Agent as collateral for the payment and performance of the obligations
      of
      such Borrower under this Agreement. The Agent shall have exclusive dominion
      and
      control, including the exclusive right of withdrawal, over such account. Other
      than any interest earned on the investment of such deposits, which investments
      shall be made at the option and sole discretion of the Agent and at such
      Borrower’s risk and expense, such deposits shall not bear interest. Interest or
      profits, if any, on such investments shall accumulate in such account. Moneys
      in
      such account shall be applied by the Agent to reimburse each Issuing Bank for
      LC
      Disbursements under Letters of Credit issued for the account of such Borrower
      for which it has not been reimbursed and, to the extent not so applied, shall
      be
      held for the 

     

    
      
        
        

      

      
        26

        
          

        

      

      
        
        

      

    

     

    satisfaction
      of future reimbursement obligations under Letters of Credit issued for the
      account of such Borrower or, if the maturity of the Loans has been accelerated
      (but subject to the consent of Lenders with LC Exposures representing greater
      than 50% of the total LC Exposure), be applied to satisfy other obligations
      of
      such Borrower under this Agreement. If any Borrower is required to provide
      an
      amount of cash collateral hereunder as a result of the occurrence of a Default
      with respect to such Borrower, such amount (to the extent not applied as
      aforesaid) shall be returned to such Borrower within three Business Days after
      all Defaults with respect to such Borrower have been cured or
      waived.

     

    (j)
        Designation
      of Additional Issuing Banks.
      From
      time to time, the Borrowers may by notice to the Agent and the Lenders designate
      as additional Issuing Banks one or more Lenders that agree to serve in such
      capacity as provided below. The acceptance by a Lender of any appointment as
      an
      Issuing Bank hereunder shall be evidenced by an agreement (an “Issuing
      Bank Agreement”),
      which
      shall be in a form satisfactory to the Borrowers and the Agent, shall set forth
      the LC Commitment of such Lender and shall be executed by such Lender, the
      Borrowers and the Agent and, from and after the effective date of such
      agreement, (i) such Lender shall have all the rights and obligations of an
      Issuing Bank under this Agreement and the other Loan Documents and (ii)
      references herein and in the other Loan Documents to the term “Issuing Bank”
      shall be deemed to include such Lender in its capacity as an Issuing
      Bank.

     

    2.7.  Types
      of Advances.
      Revolving Advances may be Floating Rate Advances or Eurodollar Advances, or
      a
      combination thereof, selected by the applicable Borrower in accordance with
      Sections 2.10 and 2.11. Swingline Loans will be Floating Rate Advances.
      Competitive Loans may be Eurodollar Rate Advances or Fixed Rate Advances, or
      a
      combination thereof, selected by the applicable Borrower in accordance with
      Section 2.4.

     

    2.8.  Facility
      Fee; Letter of Credit Fees; Reductions in Aggregate Commitment.

     

    2.8.1
        Facility Fee.  The Company agrees to pay to the
      Agent for the account of each Lender a facility fee (the “Facility Fee”) at a

    per
      annum
      rate equal to the  Applicable Fee Rate on such Lender’s Commitment
      (whether used or unused) from and including the 

    Closing
      Date to and including the Facility Termination Date, payable quarterly in
      arrears on each Payment Date hereafter and on the Facility Termination
      Date, 

    provided
      that, if any Lender continues to have Revolving Credit Exposure outstanding
      hereunder after the termination of its Commitment (including, without

    limitation,
      during any period when Loans or Letters of Credit may be outstanding but new
      Loans or Letters of Credit may not be borrowed or issued hereunder),

    then
      the
      Facility Fee shall continue to accrue on the aggregate principal amount of
      the
      Revolving Credit Exposure of such Lender until such Lender ceases to

    have
      any
      Revolving Credit
      Exposure and shall be payable on demand.<?xml:namespace prefix = o
      />

     

    2.8.2
        Letter
      of Credit Fees.
      Each
      Borrower agrees, severally and not jointly with the other Borrowers, to pay
      (i)
      to the Agent for the account of each Lender a participation fee with respect
      to
      its participations in Letters of Credit issued for the account of such Borrower
      (the “LC Participation Fee”), which shall accrue at the Applicable Fee Rate on
      the average daily amount of 

     

    
      
        
        

      

      
        27

        
          

        

      

      
        
        

      

    

     

    that
      portion of such Lender’s LC Exposure (excluding any portion thereof attributable
      to unreimbursed LC Disbursements) attributable to Letters of Credit

    issued  for
      the account of such Borrower during the period from and including the Closing
      Date to but excluding the later of the date on which such Lender’s 

    Commitment
      terminates and the date on which such Lender ceases to have any LC Exposure,
      and
      (ii) to each Issuing Bank a fronting fee, which shall accrue at 

    the
      rate
      or rates per annum
      separately agreed upon between such Borrower and such Issuing Bank on the
      average daily amount of the LC Exposure attributable 

    to
      Letters of Credit issued by such Issuing Bank for the account of such Borrower
      (excluding any portion thereof attributable to unreimbursed LC 

    disbursements)
      during the period from and including the Closing Date to but excluding the
      later
      of the date of termination of the Commitments and the date on 

    which
      there ceases to be any LC Exposure, as well as each Issuing Bank’s standard fees
      with respect to the issuance, amendment, renewal or extension of any

    Letter
      of
      Credit issued by such Issuing Bank for the account of such Borrower or
      processing of drawings thereunder. LC Participation Fees and fronting fees
      

    accrued
      through and including the last day of March, June, September and December of
      each year shall be payable on the third Business Day following such

    last
      day,
      commencing on the first such date to occur after the Closing Date; provided
      that all
      such fees accrued for the account of any Borrower shall be payable 

    on
      the
      Availability Termination Date for such Borrower and any such fees accruing
      after
      the Availability Termination Date for such Borrower shall be payable on

    demand.
      Any other fees payable to an Issuing Bank pursuant to this paragraph shall
      be
      payable promptly upon receipt of an invoice therefor.

     

    2.8.3
        Termination
      of and Reductions in Aggregate Commitment and Subsidiary
      Sublimits.
      The
      Aggregate Commitment and the Commitment of each Lender will automatically
      terminate on the Commitment Termination Date. The Company may permanently reduce
      the Aggregate Commitment and each Borrowing Subsidiary may permanently
      reduce its respective Subsidiary Sublimit, in whole or in part, ratably among
      the Lenders in integral multiples of $5,000,000, upon at least ten (10) Business
      Days’ written notice to the Agent, which notice shall specify the amount of any
      such reduction, provided, however,
      that (i)
      the amount of the Aggregate Commitment may not be reduced below the
      Aggregate Outstanding Credit Exposure and (ii) the Subsidiary Sublimit
      of
      any Borrowing Subsidiary may not be reduced below the Subsidiary Credit Exposure
      of such Borrowing Subsidiary.

     

    2.9.  Minimum
      Amount of Each Advance.
      Each
      Eurodollar Advance shall be in the minimum amount of $5,000,000 (and in
      multiples of $1,000,000 if in excess thereof), and each Floating Rate Advance
      shall be in the minimum amount of $5,000,000 (and in multiples of $1,000,000
      if
      in excess thereof), provided, however,
      that (i)
      any Floating Rate Advance may be in the amount of the Available Aggregate
      Commitment and (ii)  any Floating Rate Advance to a Borrowing Subsidiary
      may be in the amount equal to the lesser of the Available Aggregate Commitment
      and the amount by which the Subsidiary Sublimit of such Borrowing Subsidiary
      exceeds the Subsidiary Credit Exposure of such Borrowing
      Subsidiary.

    2.10.  Optional
      Principal Payments.
      Each
      Borrower may from time to time pay, without penalty or premium, all outstanding
      Floating Rate Advances of such Borrower, or any portion of such outstanding
      Floating Rate Advances, in a minimum aggregate amount of $5,000,000 or any
      integral multiple of $1,000,000 in excess thereof, upon one (1) Business Day’s
      prior notice to the Agent. Each Borrower may from time to time pay, subject
      to
      the payment of any funding indemnification amounts required by Section 3.4
      but
      without penalty or premium, all outstanding Eurodollar Advances of such
      Borrower, or, in a minimum aggregate amount of $5,000,000 or any integral
      multiple of $1,000,000 in excess thereof, any portion of such outstanding
      Eurodollar Advances upon three (3) Business Days’ prior notice to the Agent;
provided
      that no
      Competitive Loan may be prepaid without the consent of the applicable
      Lender.

     

    2.11.  Method
      of Selecting Types and Interest Periods for New Revolving
      Advances.
      The
      applicable Borrower shall select the Type of each Revolving Advance and, in
      the
      case of each Revolving Eurodollar Advance, the Interest Period applicable
      thereto; provided
      that
      there shall be no more than three (3) Interest Periods in effect with respect
      to
      all of the Revolving Loans of any single Borrower at any time, unless such
      limit
      has been waived by the Agent in its sole discretion. The applicable Borrower
      shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than
      11:00 a.m. (New York time) on the Borrowing Date of each Revolving Floating
      Rate
      Advance and three Business Days before the Borrowing Date for each Revolving
      Eurodollar Advance, specifying:

     

    
      	(i)  	
              the
                Borrower requesting such Borrowing,

            

    

     

    
      	(ii)  	
              the
                Borrowing Date, which shall be a Business Day, of such
                Advance,

            

    

     

    
      	(iii)  	
              the
                aggregate amount of such Advance,

            

    

     

    
      	(iv)  	
              the
                Type of Advance selected, and

            

    

     

    
      	(v)  	
              in
                the case of each Eurodollar Advance, the Interest Period applicable
                thereto.

            

    

     

    The
      Agent
      shall provide written notice of each request for borrowing under this Section
      2.11 by 11:00 a.m. (New York time) (or, if later, within one hour after receipt
      of the applicable Borrowing Notice from such Borrower) on each Borrowing Date
      for each Floating Rate Advance or on the third Business Day prior to each
      Borrowing Date for each Eurodollar Advance, as applicable. Not later than 1:00
      p.m. (New York time) on each Borrowing Date, each Lender shall make available
      its Revolving Loan or Revolving Loans in Federal or other funds immediately
      available in New York to the Agent at its address specified pursuant
      to
      Article XIII. The Agent will promptly make the funds so received from the
      Lenders available to such Borrower at the Agent’s aforesaid
      address.

     

    2.12.  Conversion
      and Continuation of Outstanding Revolving Advances; No Conversion or
      Continuation of Revolving Eurodollar Advances After Default.
      Revolving Floating Rate Advances shall continue as Floating Rate Advances unless
      and until such Revolving Floating Rate Advances are converted into Revolving
      Eurodollar Advances pursuant to this Section 2.12 or are repaid in accordance
      with Section 2.10. Each Revolving Eurodollar Advance shall continue as a
      Eurodollar Advance until the end of the then applicable Interest Period
      therefor, at which time such Revolving Eurodollar Advance shall be
      automatically

    converted
      into a Revolving Floating Rate Advance unless (x) such Revolving Eurodollar
      Advance is or was repaid in accordance with Section 2.10 or (y) the applicable
      Borrower shall have given the Agent a Conversion/Continuation Notice (as defined
      below) requesting that, at the end of such Interest Period, such Revolving
      Eurodollar Advance continue as a Revolving Eurodollar Advance for the same
      or
      another Interest Period. Subject to the terms of Section 2.9, a Borrower may
      elect from time to time to convert all or any part of a Revolving Advance of
      any
      Type into any other Type or Types of Advances; provided
      that any
      conversion of any Revolving Eurodollar Advance shall be made on, and only on,
      the last day of the Interest Period applicable thereto. Notwithstanding anything
      to the contrary contained in this Section 2.12, during the continuance of a
      Default or an Unmatured Default with respect to a Borrower, the Agent may (or
      shall at the direction of the Required Lenders), by notice to such Borrower,
      declare that no Revolving Advance of such Borrower may be made, converted or
      continued as a Eurodollar Advance. The applicable Borrower shall give the Agent
      irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a
      Revolving Advance or continuation of a Revolving Eurodollar Advance not later
      than 11:00 a.m. (New York time) at least one (1) Business Day, in the case
      of a
      conversion into a Revolving Floating Rate Advance, or three (3) Business Days,
      in the case of a conversion into or continuation of a Revolving Eurodollar
      Advance, prior to the date of the requested conversion or continuation,
      specifying:

     

    
      	(i)  	
              the
                requested date, which shall be a Business Day, of such conversion
                or
                continuation, 

            

    

     

    
      	(ii)  	
              the
                aggregate amount and Type of the Advance to be converted or continued,
                and
                

            

    

     

    
      	(iii)  	
              the
                amount of the Advance to be converted into or continued as a Eurodollar
                Advance and the duration of the Interest Period applicable
                thereto.

            

    

     

    This
      Section shall not apply to Competitive Loans or Swingline Loans, which may
      not
      be converted or continued.

     

    2.13.   Interest
      Rates, etc.
      Each
      Floating Rate Advance shall bear interest on the outstanding principal amount
      thereof, for each day from and including the date such Advance is made or is
      automatically converted from a Eurodollar Advance into a Floating Rate Advance
      pursuant to Section 2.12, to but excluding the date it is paid or is converted
      into a Eurodollar Advance pursuant to Section 2.12, at a rate per annum equal
      to
      the Floating Rate for such day. Changes in the rate of interest on that portion
      of any Advance maintained as a Floating Rate Advance will take effect
      simultaneously with each change in the Alternate Base Rate. Each Eurodollar
      Advance shall bear interest on the outstanding principal amount thereof from
      and
      including the first day of the Interest Period applicable thereto to (but not
      including) the last day of such Interest Period at the Eurodollar Rate
      determined by the Agent as applicable to such Eurodollar Advance based upon
      the
      applicable Borrower’s selections under Sections 2.10 and 2.11 and otherwise in
      accordance with the terms hereof. Each Fixed Rate Advance shall bear interest
      at
      the Fixed Rate applicable thereto.

     

    2.14.  Rates
      Applicable After Default.
      During
      the continuance of a Default with respect to any Borrower, the Required Lenders
      may, at their option, by notice to such Borrower (which notice may be revoked
      at
      the option of the Required Lenders notwithstanding any provision of

     

    
      
        
        

      

      
        30

        
          

        

      

      
        
        

      

    

     

    Section 8.2
      requiring unanimous consent of the Lenders to changes in interest rates),
      declare that (i) each Eurodollar Advance shall bear interest for the remainder
      of the applicable Interest Period at the rate otherwise applicable during such
      Interest Period plus 2% per annum and (ii) each Floating Rate Advance shall
      bear
      interest at a rate per annum equal to the Floating Rate in effect from time
      to
      time plus 2% per annum, provided
      that,
      during the continuance of a Default with respect to any Borrower under Section
      7.6 or 7.7, the interest rates set forth in clauses (i) and (ii) above shall
      be
      applicable to all Advances, fees and other Obligations of such Borrower
      hereunder without any election or action on the part of the Agent or any
      Lender. 

     

    2.15.  Funding
      of Loans; Method of Payment.
      All
      payments of the Obligations hereunder shall be made, without setoff, deduction
      or counterclaim, in immediately available funds to the Agent at the Agent’s
      address specified pursuant to Article XIII, or at any other Lending Installation
      of the Agent specified in writing by the Agent, by 12:00 noon (New York time)
      on
      the date when due and shall be applied ratably by the Agent among the Lenders.
      Each payment delivered to the Agent for the account of any Lender shall be
      delivered promptly by the Agent to such Lender in the same type of funds that
      the Agent received at its address specified pursuant to Article XIII or at
      any
      Lending Installation specified in a notice received by the Agent from such
      Lender. The Agent is hereby authorized to charge the account of any Borrower
      maintained with JPMCB for each payment of principal, interest and fees owed
      by
      such Borrower as it becomes due hereunder.

     

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

     

    
      	(ii)  	
              The
                Agent shall also maintain accounts in which it will record (a) the
                date
                and the amount of each Loan made to each Borrower hereunder, the
                Type
                thereof and the Interest Period (in the case of a Eurodollar Advance)
                with
                respect thereto, (b) the amount of any principal or interest due
                and
                payable or to become due and payable from each Borrower to each Lender
                hereunder, (c) the effective date and amount of each Assignment Agreement
                delivered to and accepted by it pursuant to Section 12.3 and the
                parties
                thereto, (d) the amount of any sum received by the Agent hereunder
                from
                each Borrower and each Lender’s share thereof, and (e) all other
                appropriate debits and credits as provided in this Agreement, including,
                without limitation, all fees, charges, expenses and
                interest.

            

    

     

    
      	(iii)  	
              The
                entries maintained in the accounts maintained pursuant to paragraphs
                (i)
                and (ii) above shall be prima facie
                evidence absent manifest error of the existence and amounts of the
                Obligations therein recorded; provided, however,
                that the failure of the Agent or any Lender to maintain such accounts
                or
                any error therein shall not in any manner affect the obligation of
                such
                Borrower to repay the Obligations in accordance with their terms.
                

            

    

     

    
      	(iv)  	
              Any
                Lender may request that its Loans be evidenced by a promissory note
                in
                substantially the form of Exhibit E (a “Note”). In such event, the
                applicable 

            

    

     

     

    
      
        
        

      

      
        31

        
          

        

      

      
        
        

      

    

     

    
      Borrower
        shall prepare, execute and deliver to such Lender such Note payable to the
        order
        of such Lender. Thereafter, the Loans evidenced by such Note and 

      interest
        thereon shall at all times (prior to any assignment pursuant to Section 12.3)
        be
        represented by one or more Notes payable to the order of the payee named
        

      therein,
        except to the extent that any such Lender subsequently returns any such Note
        for
        cancellation and requests that such Loans once again be evidenced as

      described
        in paragraphs (i) and (ii) above.

       

    

    2.17.  Telephonic
      Notices.
      Each
      Borrower hereby authorizes the Lenders and the Agent to extend, convert or
      continue Advances, effect selections of Types of Advances and to transfer funds
      based on telephonic notices made by any person or persons the Agent or any
      Lender in good faith believes to be acting on behalf of such Borrower, it being
      understood that the foregoing authorization is specifically intended to allow
      Borrowing Notices and Conversion/Continuation Notices to be given
      telephonically. Each Borrower agrees to deliver promptly to the Agent a written
      confirmation, signed by an Authorized Officer, if such confirmation is requested
      by the Agent or any Lender, of each telephonic notice. If the written
      confirmation differs in any material respect from the action taken by the Agent
      and the Lenders, the records of the Agent and the Lenders shall govern absent
      manifest error. 

     

    2.18.  Interest
      Payment Dates; Interest and Fee Basis.
      Interest accrued on each Floating Rate Advance shall be payable in arrears
      on
      each Payment Date, commencing with the first such date to occur after the
      Closing Date, on any date on which such Floating Rate Advance is prepaid,
      whether due to acceleration or otherwise, and at maturity. Interest accrued
      on
      that portion of the outstanding principal amount of any Floating Rate Advance
      converted into a Eurodollar Advance on a day other than a Payment Date shall
      be
      payable on the date of conversion. Interest accrued on each Eurodollar Advance
      shall be payable on the last day of each applicable Interest Period, on any
      date
      on which the Eurodollar Advance is prepaid, whether by acceleration or
      otherwise, and at maturity. Interest accrued on each Eurodollar Advance having
      an Interest Period longer than three months shall also be payable on the last
      day of each three-month interval during such Interest Period. Interest accrued
      on each Fixed Rate Loan shall be payable on the last day of the Interest Period
      applicable to the Advance of which such Loan is a part and, in the case of
      a
      Fixed Rate Advance with an Interest Period of more than 90 days’ duration
      (unless otherwise specified in the applicable Competitive Bid Request), each
      day
      prior to the last day of such Interest Period that occurs at intervals of 90
      days’ duration after the first day of such Interest Period, and any other dates
      that are specified in the applicable Competitive Bid Request as dates for
      payment of interest with respect to such Advance. Interest accrued on each
      Swingline Loan shall be payable on the day that such Loan is required to be
      repaid. Interest accrued on any Advance that is not paid when due shall be
      payable on demand and on the date of payment in full. Interest on Eurodollar
      Advances, Fixed Rate Loans and fees hereunder shall be calculated for actual
      days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances
      shall be calculated for actual days elapsed on the basis of a 365/366-day year.
      Interest shall be payable for the day an Advance is made but not for the day
      of
      any payment on the amount paid if payment is received prior to 12:00 noon (New
      York time) at the place of payment. If any payment of principal of or interest
      on an Advance, any fees or any other amounts payable to the Agent or any Lender
      hereunder shall become due on a day which is not a Business Day, such payment
      shall be made on the next succeeding Business Day and, in 

     

    
      
        
        

      

      
        32

        
          

        

      

      
        
        

      

    

     

    the
      case
      of principal payment, such extension of time shall be included in computing
      interest, fees and commissions in connection with such payment.

     

    2.19.  Notification
      of Advances, Interest Rates, Prepayments and Commitment Reductions; Availability
      of Loans.
      Promptly after receipt thereof, the Agent will notify each Lender in writing
      of
      the contents of each Aggregate Commitment reduction notice, Borrowing Notice,
      Conversion/Continuation Notice, and repayment notice received by it hereunder.
      The Agent will notify the applicable Borrower and each Lender of the interest
      rate applicable to each Revolving Eurodollar Advance promptly upon determination
      of such interest rate and will give each Borrower and each Lender prompt notice
      of each change in the Alternate Base Rate.

     

    2.20.  Lending
      Installations.
      Each
      Lender may book its Loans at any Lending Installation selected by such Lender
      and may change its Lending Installation from time to time. All terms of this
      Agreement shall apply to any such Lending Installation and the Loans and any
      Notes issued hereunder shall be deemed held by each Lender for the benefit
      of
      any such Lending Installation. Each Lender may, by written notice to the Agent
      and the Borrowers in accordance with Article XIII, designate replacement or
      additional Lending Installations through which Loans will be made by it and
      for
      whose account Loan payments are to be made.

     

    2.21.  Non-Receipt
      of Funds by the Agent.
      Unless
      the applicable Borrower or a Lender, as the case may be, notifies the Agent
      prior to the date (or, in the case of a Lender with respect to a Revolving
      Floating Rate Advance under Section 2.11, prior to the time) on which it is
      scheduled to make payment to the Agent of (i) in the case of a Lender, the
      proceeds of a Loan or (ii) in the case of a Borrower, a payment of principal,
      interest or fees to the Agent for the account of the Lenders, that it does
      not
      intend to make such payment, the Agent may assume that such payment has been
      made. The Agent may, but shall not be obligated to, make the amount of such
      payment available to the intended recipient in reliance upon such assumption.
      If
      such Lender or such Borrower, as the case may be, has not in fact made such
      payment to the Agent, the recipient of such payment shall, on demand by the
      Agent, repay to the Agent the amount so made available together with interest
      thereon in respect of each day during the period commencing on the date such
      amount was so made available by the Agent until the date the Agent recovers
      such
      amount at a rate per annum equal to (x) in the case of payment by a Lender,
      the
      Federal Funds Effective Rate for such day for the first three days and,
      thereafter, the interest rate applicable to the relevant Loan or (y) in the
      case
      of payment by a Borrower, the interest rate applicable to the relevant
      Loan.

     

    2.22.  Replacement
      of Lender.
      If any
      Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional
      payment to any Lender or if any Lender’s obligation to make or continue, or to
      convert Floating Rate Advances into, Eurodollar Advances shall be suspended
      pursuant to Section 3.3 (any Lender so affected an “Affected Lender”), the
      Borrowers may elect, if such amounts continue to be charged or such suspension
      is still effective, to terminate or replace the Commitment of such Affected
      Lender, provided
      that no
      Default or Unmatured Default shall have occurred and be continuing at the time
      of such termination or replacement, and provided further
      that,
      concurrently with such termination or replacement, (i) if the Affected Lender
      is
      being replaced, another bank or other entity which is reasonably satisfactory
      to
      the Borrowers and the Agent shall agree, as of such date, to purchase for cash
      at face amount the Outstanding Credit Exposure of the Affected Lender pursuant
      to an Assignment Agreement

     

    
      
        
        

      

      
        33

        
          

        

      

      
        
        

      

    

     

    substantially
      in the form of Exhibit C and to become a Lender for all purposes under this
      Agreement and to assume all obligations of the Affected Lender to be terminated
      as of such date and to comply with the requirements of Section 12.3 applicable
      to assignments, and (ii) each Borrower shall pay to such Affected Lender in
      immediately available funds on the day of such replacement (A) all interest,
      fees and other amounts then accrued but unpaid to such Affected Lender by such
      Borrower hereunder to and including the date of termination, including without
      limitation payments due to such Affected Lender under Sections 3.1, 3.2 and
      3.5,
      and (B) an amount, if any, equal to the payment which would have been due to
      such Lender on the day of such replacement under Section 3.4 had the Loans
      of
      such Affected Lender been prepaid on such date rather than sold to the
      replacement Lender, in each case to the extent not paid by the purchasing lender
      and (iii) if the Affected Lender is being terminated, each Borrower shall pay
      to
      such Affected Lender all Obligations due from such Borrower to such Affected
      Lender (including the amounts described in the immediately preceding clauses
      (i)
      and (ii) plus the outstanding principal balance of such Affected Lender’s
      Advances and the amount of such Lender’s funded participations in unreimbursed
      LC Disbursements). Notwithstanding the foregoing, the Borrowers may not
      terminate the Commitment of an Affected Lender if, after giving effect to such
      termination, (x) the Aggregate Outstanding Credit Exposure would exceed
      the
      Aggregate Commitment, or (y) the Subsidiary Credit Exposure of any
      Borrowing Subsidiary would exceed the Subsidiary Sublimit of such Borrowing
      Subsidiary.

     

    2.23.  Extension
      of Commitment Termination Date and Borrowing Subsidiary Maturity
      Dates.
      (a)
       Extension
      of Commitment Termination Date.
      The
      Company may, by notice to the Agent (which shall promptly deliver a copy to
      each
      of the Lenders) given not less than 45 days and not more than 60 days
      prior
      to any of the first four anniversaries of the Closing Date (a “Commitment
      Extension Request”), request that the Lenders extend the Commitment Termination
      Date for an additional period of one year. Each Lender shall, by notice to
      the
      Company and the Agent given not later than the 20th day after the date of the
      Agent’s receipt of the Company’s Commitment Extension Request, advise the
      Company whether or not it agrees to the requested extension (each Lender
      agreeing to a requested extension being called a “Consenting Lender” and each
      Lender declining to agree to a requested extension being called a “Declining
      Lender”). Any Lender that has not so advised the Company and the Agent by such
      day shall be deemed to have declined to agree to such extension and shall be
      a
      Declining Lender. If Lenders constituting the Required Lenders shall have agreed
      to a Commitment Extension Request, then the Commitment Termination Date shall,
      as to the Consenting Lenders, be extended to the first anniversary of the
      Commitment Termination Date theretofore in effect.  The decision
      to
      agree or withhold agreement to any Commitment Extension Request shall be at
      the
      sole discretion of each Lender. The Commitment of any Declining Lender shall
      terminate on the Commitment Termination Date in effect prior to giving effect
      to
      any such extension (such Commitment Termination Date being called the “Existing
      Commitment Termination Date”). The principal amount of any outstanding Loans
      made by Declining Lenders (including any such Loans made to Borrowing
      Subsidiaries, whether or not the Maturity Dates applicable to such Borrowing
      Subsidiaries shall have been extended as provided in paragraph (b) of this
      Section), together with any accrued interest thereon and any accrued fees and
      other amounts payable to or for the account of such Declining Lenders hereunder,
      shall be due and payable on the Existing Commitment Termination Date, and on
      the
      Existing Commitment Termination Date, the Borrowers shall also make such other
      prepayments of their respective Loans pursuant to Section 2.10 as shall be
      required in order that, after giving effect to the termination of the
      Commitments

     

    
      
        
        

      

      
        34

        
          

        

      

      
        
        

      

    

     

     of,
      and all payments to, Declining Lenders pursuant to this sentence, (i) the
      Aggregate Outstanding Credit Exposure will not exceed the Aggregate Commitment
      and (ii) the Committed Credit Exposure of each Lender will not exceed its
      Commitment. Notwithstanding the foregoing provisions of this paragraph, the
      Company shall have the right, pursuant to Section 12.3, at any time prior to
      the
      Existing Commitment Termination Date, to replace a Declining Lender with a
      Lender or other financial institution that will agree to a Commitment Extension
      Request, and any such replacement Lender shall for all purposes constitute
      a
      Consenting Lender. Notwithstanding the foregoing, no extension of the Commitment
      Termination Date pursuant to this paragraph shall become effective unless (i)
      the Agent shall have received documents consistent with those delivered with
      respect to the Company under Sections 4.1.1 through 4.1.6, giving effect to
      such
      extension and (ii) on the anniversary of the Closing Date that immediately
      follows the date on which the Company delivers the applicable Commitment
      Extension Request, the conditions set forth in Sections 4.2.1 and 4.2.2 shall
      be
      satisfied (with all references in Sections 5.5 and 5.7 to “the date of this
      Agreement” being deemed to be references to the date of such anniversary of the
      Closing Date), and the Agent shall have received a certificate to that effect
      dated such date and executed by the chief financial officer, the controller
      or
      the treasurer of the Company. 

     

    (b)
        Extension
      of Borrowing Subsidiary Maturity Dates.
      Any
      Borrowing Subsidiary may, by notice (a “Subsidiary Maturity Date Extension
      Request”) to the Agent (which shall promptly deliver a copy to each of the
      Lenders) given not less than 45 days and not more than 60 days prior
      to the
      then-current Maturity Date with respect to such Borrowing Subsidiary, request
      an
      extension of such Maturity Date with respect to such Borrowing Subsidiary to
      a
      date 364 days after such Maturity Date (the Maturity Date in effect prior to
      any
      such extension being called the “Existing Maturity Date” with respect to such
      Borrowing Subsidiary) and on or prior to (but in no event after) the Commitment
      Termination Date (including any date to which the Commitment Termination Date
      has been extended or is simultaneously being extended pursuant to paragraph
      (a)
      above) or, if the Commitment Termination Date shall have been or is
      simultaneously being extended as to some but not all of the Lenders, the latest
      date to which the Commitment Termination Date applicable to any Lenders shall
      have been or is being so extended. Each Lender shall, by notice to such
      applicable Borrowing Subsidiary, the Company and the Agent given not later
      than
      the 20th day after the date of the Agent’s receipt of such Borrowing
      Subsidiary’s Subsidiary Maturity Date Extension Request, advise such applicable
      Borrowing Subsidiary and the Company whether or not it agrees to the requested
      extension (each Lender agreeing to a requested extension being called a
“Consenting Lender” and each Lender declining to agree to a requested extension
      being called a “Declining Lender”). Any Lender that has not so advised such
      applicable Borrowing Subsidiary, the Company and the Agent by such day shall
      be
      deemed to have declined to agree to such extension and shall be a Declining
      Lender. If Lenders constituting the Required Lenders shall have agreed to a
      Subsidiary Maturity Date Extension Request, then the Maturity Date with respect
      to the applicable Borrowing Subsidiary shall, as to both the Consenting Lenders
      and the Declining Lenders, be extended to the date 364 days after the Existing
      Maturity Date with respect to such Borrowing Subsidiary; provided,
      that
      the Maturity Date with respect to a Borrowing Subsidiary shall in no event
      be
      extended beyond the latest date to which the Commitment Termination Date
      applicable to any Lenders shall have been extended. Notwithstanding the
      foregoing, no extension of the Maturity Date with respect to any Borrowing
      Subsidiary pursuant to this paragraph shall become effective unless (i) the
      Agent shall have received documents consistent with those delivered with respect
      to such Borrowing Subsidiary under Sections 4.1.1 through

     

    
      
        
        

      

      
        35

        
          

        

      

      
        
        

      

    

     

    4.1.6,
      giving effect to such extension and (ii) on the Existing Maturity Date
      applicable to such Borrowing Subsidiary, the conditions set forth in Sections
      4.2.1 and 4.2.2 shall be satisfied with respect to such Borrowing Subsidiary
      (with all references in Sections 5.5 and 5.7 to “the date of this Agreement”
      being deemed to be references to such Existing Maturity Date), and the Agent
      shall have received a certificate to that effect dated such date and executed
      by
      the chief financial officer, the controller or the treasurer of such Borrowing
      Subsidiary.

      PROTECTION; TAXES

     

    3.1.  Yield
      Protection.
      If, on
      or after the Closing Date, the adoption of any law or any governmental or
      quasi-governmental rule, regulation, policy, guideline or directive (whether
      or
      not having the force of law), or any change in any such law, rule, regulation,
      policy, guideline or directive or in the interpretation or administration
      thereof by any governmental or quasi-governmental authority, central bank or
      comparable agency charged with the interpretation or administration thereof,
      or
      compliance by any Lender or applicable Lending Installation with any request
      or
      directive (whether or not having the force of law) of any such authority,
      central bank or comparable agency:

     

    3.1.1
        subjects
      any Lender or any applicable Lending Installation to any Taxes, or changes
      the
      basis of taxation of payments (other than with respect to 

                                           
      Excluded Taxes) to any Lender in respect of its Eurodollar Loans,
      or

     

    3.1.2
        imposes
      or increases or deems applicable any reserve, assessment, insurance charge,
      special deposit or similar requirement against assets
      of,      

                   
      deposits with or for the account of, or credit extended by, any Lender or any
      applicable Lending Installation (other than reserves and assessments taken
      into

    account
      in determining the interest rate applicable to Eurodollar Advances),
      or

     

    3.1.3
        imposes
      any other condition the result of which is to increase the cost to any Lender
      or
      any applicable Lending Installation of making, funding or 

                                            maintaining
      its Commitment, Eurodollar Loans or Fixed Rate Loans or reduces any amount
      receivable by any Lender or any applicable Lending Installation in

    connection
      with its Commitment, Eurodollar Loans or Fixed Rate Loans, or requires any
      Lender or any applicable Lending Installation to make any payment

    calculated
      by reference to the amount of Commitment, Eurodollar Loans or Fixed Rate Loans
      held or interest received by it, by an amount deemed material by

    such
      Lender,

     

    and
      the
      result of any of the foregoing is to increase the cost to such Lender or
      applicable Lending Installation of making or maintaining its Commitment,
      Eurodollar Loans or Fixed Rate Loans or to reduce the return received by such
      Lender or applicable Lending Installation in connection with such Commitment,
      Eurodollar Loans or Fixed Rate Loans, then, within 15 days of demand,
      accompanied by the written statement required by Section 3.6, by such Lender,
      the Borrowers 

     

     

    
      
        
        

      

      
        36

        
          

        

      

      
        
        

      

    

     

    shall
      pay
      such Lender such additional amount or amounts as will compensate such Lender
      for
      such increased cost or reduction in amount received.

     

    3.2.  Changes
      in Capital Adequacy Regulations.
      If a
      Lender determines the amount of capital required or expected to be maintained
      by
      such Lender, any Lending Installation of such Lender or any corporation
      controlling such Lender is increased as a result of a Change, then, within
      15
      days of demand, accompanied by the written statement required by Section 3.6,
      by
      such Lender, the Borrowers shall pay such Lender the amount necessary to
      compensate for any shortfall in the rate of return on the portion of such
      increased capital which such Lender determines is attributable to this
      Agreement, its Outstanding Credit Exposure or its Commitment hereunder (after
      taking into account such Lender’s policies as to capital adequacy). “Change”
      means (i) any change after the Closing Date in the Risk-Based Capital Guidelines
      or (ii) any adoption of, or change in, or change in the interpretation or
      administration of any other law, governmental or quasi-governmental rule,
      regulation, policy, guideline, interpretation, or directive (whether or not
      having the force of law) after the Closing Date which affects the amount of
      capital required or expected to be maintained by any Lender or any Lending
      Installation or any corporation controlling any Lender. “Risk-Based Capital
      Guidelines” means (i) the risk-based capital guidelines in effect in the United
      States on the Closing Date, including transition rules, and (ii) the
      corresponding capital regulations promulgated by regulatory authorities outside
      the United States implementing the July 1988 report of the Basle Committee
      on
      Banking Regulation and Supervisory Practices Entitled “International Convergence
      of Capital Measurements and Capital Standards,” including transition rules, and
      any amendments to such regulations adopted prior to the Closing
      Date.

     

    3.3.  Availability
      of Types of Advances.
      If (x)
      any Lender determines that maintenance of its Eurodollar Loans at a suitable
      Lending Installation would violate any applicable law, rule, regulation, or
      directive, whether or not having the force of law, or (y) the Required Lenders
      determine that (i) deposits of a type and maturity appropriate to match fund
      Eurodollar Advances are not available or (ii) the interest rate applicable
      to
      Eurodollar Advances does not accurately reflect the cost of making or
      maintaining Eurodollar Advances, or (iii) no reasonable basis exists for
      determining the Eurodollar Base Rate, then the Agent shall suspend the
      availability of Eurodollar Advances and require any affected Eurodollar Advances
      to be repaid or converted to Floating Rate Advances on the respective last
      days
      of the then current Interest Periods with respect to such Loans or within such
      earlier period as required by law, subject to the payment of any funding
      indemnification amounts required by Section 3.4.

     

    3.4.  Funding
      Indemnification.
      If any
      payment of a Eurodollar Advance or a Fixed Rate Loan occurs on a date which
      is
      not the last day of the applicable Interest Period, whether because of
      acceleration, prepayment or otherwise, or a Eurodollar Advance is not made
      or
      continued, a Fixed Rate Loan is not made or a Floating Rate Advance is not
      converted into a Eurodollar Advance, on the date specified by the applicable
      Borrower for any reason other than default by the Lenders, or a Eurodollar
      Advance or Fixed Rate Loan is not prepaid on the date specified by such Borrower
      for any reason, such Borrower will indemnify each Lender for any loss or cost
      incurred by it resulting therefrom, including, without limitation, any loss
      or
      cost in liquidating or employing deposits acquired to fund or maintain such
      Eurodollar Advance or Fixed Rate Loan.

    3.5.  Taxes.
      (i)
      All
      payments by any Borrower to or for the account of any Lender or the Agent
      hereunder or under any Note shall be made free and clear of and without
      deduction for any and all Taxes. If a Borrower shall be required by law to
      deduct any Taxes from or in respect of any sum payable hereunder by such
      Borrower to any Lender or the Agent, (a) 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 3.5) such Lender or
      the
      Agent (as the case may be) receives an amount equal to the sum it would have
      received had no such deductions been made, (b) such Borrower shall make
      such deductions, (c) such Borrower shall pay the full amount deducted to the
      relevant authority in accordance with applicable law and (d) such Borrower
      shall
      furnish to the Agent the original copy of a receipt evidencing payment thereof
      or, if a receipt cannot be obtained with reasonable efforts, such other evidence
      of payment as is reasonably acceptable to the Agent, in each case within 30
      days
      after such payment is made.

     

    
      	(ii)  	
              In
                addition, the Borrowers severally agree to pay any present or future
                stamp
                or documentary taxes and any other excise or property taxes, charges
                or
                similar levies which arise from any payment made hereunder or under
                any
                Note or from the execution or delivery of, or otherwise with respect
                to,
                this Agreement or any Note (“Other
                Taxes”).

            

    

     

    
      	(iii)  	
              The
                Borrowers shall indemnify the Agent and each Lender for the full
                amount of
                Taxes or Other Taxes (including, without limitation, any Taxes or
                Other
                Taxes imposed on amounts payable under this Section 3.5) paid by
                the Agent
                or such Lender and any liability (including penalties, interest and
                expenses) arising therefrom or with respect thereto. Payments due
                under
                this indemnification shall be made within 30 days of the date the
                Agent or
                such Lender makes demand therefor pursuant to Section
                3.6.

            

    

     

    
      	(iv)  	
              Each
                Lender that is not incorporated under the laws of the United States
                of
                America or a state thereof (each a “Non-U.S. Lender”) agrees that it will,
                not more than ten Business Days after the date on which it becomes
                a party
                to this Agreement (but in any event before a payment is due to it
                hereunder), (i) deliver to the Company and the Agent two duly completed
                copies of United States Internal Revenue Service Form W-8BEN or W-8ECI,
                certifying in either case that such Lender is entitled to receive
                payments
                under this Agreement without deduction or withholding of any United
                States
                federal income taxes, or (ii) in the case of a Non-U.S. Lender that
                is
                fiscally transparent, deliver to the Agent a United States Internal
                Revenue Form W-8IMY together with the applicable accompanying forms,
                W-8
                or W-9, as the case may be, and certify that it is entitled to an
                exemption from United States withholding tax. Each Non-U.S. Lender
                further
                undertakes to deliver to each of the Borrowers and the Agent (x)
                renewals
                or additional copies of such form (or any successor form) on or before
                the
                date that such form expires or becomes obsolete, and (y) after the
                occurrence of any event requiring a change in the most recent forms
                so
                delivered by it, such additional forms or amendments thereto as may
                be
                reasonably requested by the Borrowers or the Agent. All forms or
                amendments described in the preceding sentence shall certify that
                such
                Lender is entitled to receive payments under this Agreement without
                deduction or withholding of any United States federal income

      taxes,
        unless
        an event
        (including without limitation any change in treaty, law or regulation) has
        occurred prior to the date on 

      which any  such delivery  would  otherwise
        be required which renders all such forms inapplicable or which would prevent
        such Lender from duly completing and 

      delivering
        any such form or amendment with respect to it and such Lender advises the
        Borrowers and the Agent that it is not capable of receiving payments without
        

      any
        deduction or withholding of United States federal income tax.

    

     

    
      	(v)  	
              For
                any period during which a Non-U.S. Lender has failed to provide any
                Borrower with an appropriate form pursuant to clause (iv) above (unless
                such failure is due to a change in treaty, law or regulation, or
                any
                change in the interpretation or administration thereof by any governmental
                authority, occurring subsequent to the date on which such Non-U.S.
                Lender
                became a party to this Agreement), such Non-U.S. Lender shall not
                be
                entitled to indemnification under this Section 3.5 with respect to
                Taxes
                imposed by the United States; provided
                that, should a Non-U.S. Lender which is otherwise exempt from or
                subject
                to a reduced rate of withholding tax become subject to Taxes because
                of
                its failure to deliver a form required under clause (iv) above, each
                Borrower shall take such steps as such Non-U.S. Lender shall reasonably
                request to assist such Non-U.S. Lender to recover such
                Taxes.

            

    

     

    
      	(vi)  	
              Any
                Lender that is entitled to an exemption from or reduction of withholding
                tax with respect to payments under this Agreement or any Note pursuant
                to
                the law of any relevant jurisdiction or any treaty shall deliver
                to the
                Company (with a copy to the Agent), at the time or times prescribed
                by
                applicable law, such properly completed and executed documentation
                prescribed by applicable law as will permit such payments to be made
                without withholding or at a reduced
                rate.

            

    

     

    
      	(vii)  	
              If
                the U.S. Internal Revenue Service or any other governmental authority
                of
                the United States or any other country or any political subdivision
                thereof asserts a claim that the Agent did not properly withhold
                tax from
                amounts paid to or for the account of any Lender (because the appropriate
                form was not delivered or properly completed, because such Lender
                failed
                to notify the Agent of a change in circumstances which rendered its
                exemption from withholding ineffective, or for any other reason),
                such
                Lender shall indemnify the Agent fully for all amounts paid, directly
                or
                indirectly, by the Agent as tax, withholding therefor, or otherwise,
                including penalties and interest, and including taxes imposed by
                any
                jurisdiction on amounts payable to the Agent under this subsection,
                together with all reasonable costs and expenses related thereto (including
                attorneys’ fees and time charges of attorneys for the Agent, which
                attorneys may be employees of the Agent). The obligations of the
                Lenders
                under this Section 3.5(vii) shall survive the payment of the Obligations
                and termination of this Agreement. 

            

    

     

    3.6.  Lender
      Statements; Survival of Indemnity.
      Each
      Lender shall deliver a written statement of such Lender to the applicable
      Borrower (with a copy to the Agent and the Company) as to the amount due, if
      any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth
      in reasonable detail the calculations upon which such Lender determined

     

    
      
        
        

      

      
        39

        
          

        

      

      
        
        

      

    

     

    such
      amount and shall be final, conclusive and binding on such Borrower in the
      absence of manifest error, and upon reasonable request of such Borrower, such
      Lender shall promptly provide supporting documentation describing and/or
      evidence of the applicable event giving rise to such amount to the extent not
      inconsistent with such Lender’s policies or applicable law. Determination of
      amounts payable under such Sections in connection with a Eurodollar Loan shall
      be calculated as though each Lender funded its Eurodollar Loan through the
      purchase of a deposit of the type, currency and maturity corresponding to the
      deposit used as a reference in determining the Eurodollar Rate applicable to
      such Loan, whether in fact that is the case or not. Unless otherwise provided
      herein, the amount specified in the written statement of any Lender shall be
      payable on demand after receipt by the applicable Borrower of such written
      statement. The obligations of each Borrower under Sections 3.1, 3.2, 3.4 and
      3.5
      shall survive payment of the Obligations and termination of this
      Agreement.

     

    3.7.  Alternative
      Lending Installation.
      To
      the
      extent reasonably possible, each Lender shall designate an alternate Lending
      Installation with respect to its Eurodollar Loans to reduce any liability of
      the
      Borrowers to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the
      unavailability of Eurodollar Advances under Section 3.3, so long as such
      designation is not, in the judgment of such Lender, disadvantageous to such
      Lender. A Lender’s designation of an alternative Lending Installation shall not
      affect the Borrowers’ rights under Section 2.22 to replace a
      Lender.

     

    3.8.  Allocation
      of Amounts Payable Among Borrowers.
      Each
      amount payable by “the Borrowers” under this Article shall be an obligation of,
      and shall be discharged (a) to the extent arising out of acts, events and
      circumstances related to a particular Borrower, by such Borrower and
      (b) otherwise, by all the Borrowers, with each Borrower being severally
      liable for such Borrower’s Contribution Percentage of such amount, provided
      that in
      consideration of the availability, on the terms set forth herein, of the entire
      amount of the Commitments in the form of borrowings by and Letters of Credit
      issued for the account of the Company, the Company agrees that, if one or more
      of the Borrowing Subsidiaries shall fail to pay any amount owed by it under
      clause (b) of this Section after a demand shall have been made by the Person
      to
      which such amount is owed, the Company shall promptly pay such amount (the
      Company hereby irrevocably waiving any defenses that might otherwise be
      available to it as a guarantor of the obligations of any Borrowing Subsidiary
      under this Section).

    Each
      Borrower represents and warrants to each Lender, each Issuing Bank and the
      Agent, as to such Borrower and, as applicable, its Subsidiaries, as of each
      of
      (i) the Closing Date, (ii) the date of the initial Credit Extension to such
      Borrower hereunder (if different from the Closing Date) and (iii) each date
      as

      and Standing.
      Such
      Borrower and each of its Subsidiaries (other than any Project Finance
      Subsidiary) is a corporation, partnership (in the case of Subsidiaries only)
      or
      limited liability company duly and properly incorporated or organized, as the
      case may be, validly existing and (to the extent such concept applies to such
      entity) in good standing under the laws of its jurisdiction of incorporation
      or
      organization and has all requisite authority to conduct its business in each
      jurisdiction in which its business is conducted.

      and Validity.
      Such
      Borrower has the power and authority and legal right to execute and deliver
      the
      Loan Documents and to perform its obligations thereunder. The execution and
      delivery by such Borrower of the Loan Documents and the performance of its
      obligations thereunder have been duly authorized by proper proceedings, and
      the

    Documents
      to which such Borrower is a party constitute legal, valid and binding
      obligations of such Borrower enforceable against such Borrower in accordance
      with their terms, except as enforceability may be limited by (i) bankruptcy,
      insolvency, fraudulent conveyance, reorganization or similar laws relating
      to or
      affecting the enforcement of creditors’ rights generally; (ii) general equitable
      principles (whether considered in a proceeding in equity or at law) and (iii)
      requirements of reasonableness, good faith and fair dealing.

     

    5.3.  No
      Conflict; Government Consent.
      Neither
      the execution and delivery by such Borrower of the Loan Documents, nor the
      consummation of the transactions therein contemplated, nor compliance with
      the
      provisions thereof will violate (i) any law, rule, regulation, order, writ,
      judgment, injunction, decree or award binding on such Borrower or any of its
      Subsidiaries or (ii) such Borrower’s or any Subsidiary’s articles or certificate
      of incorporation, partnership agreement, certificate of partnership, articles
      or
      certificate of organization, by-laws, or operating agreement or other management
      agreement, as the case may be, or (iii) the provisions of any indenture,
      instrument or agreement to which such Borrower or any of its Subsidiaries is
      a
      party or is subject, or by which it, or its Property, is bound, or conflict
      with, or constitute a default under, or result in, or require, the creation
      or
      imposition of any Lien in, of or on the Property of such Borrower or a
      Subsidiary pursuant to the terms of, any such indenture, instrument or
      agreement. No order, consent, adjudication, approval, license, authorization,
      or
      validation of, or filing, recording or registration with, or exemption by,
      or
      other action in respect of any governmental or public body or authority, or
      any
      subdivision thereof, which has not been obtained by such Borrower or any of
      its
      Subsidiaries, is required to be obtained by such Borrower or any of its
      Subsidiaries in connection with the execution and delivery of the Loan
      Documents, the borrowings and issuances of Letters of Credit under this
      Agreement, the payment and performance by such Borrower of the Obligations
      or
      the legality, validity, binding effect or enforceability of any of the Loan
      Documents.

     

    5.4.  Financial
      Statements.
      The
      December 31, 2004, consolidated financial statements of such Borrower, audited
      by PricewaterhouseCoopers LLP, for the fiscal year ended December 31, 2004,
      and
      the unaudited consolidated balance sheet of such Borrower as of March 31,
      2005, and the related unaudited statement of income and statement of cash flows
      for the three-month period then ended, copies of which have been furnished
      to
      each Lender, fairly present in all material respects (subject in the case of
      such balance sheet and statement of income for the period ended March 31,
      2005, to year-end adjustments) the consolidated financial condition of such
      Borrower at such dates and the consolidated results of the operations of such
      Borrower for the periods ended on such dates, were prepared in accordance with
      generally accepted accounting principles in effect on the dates such statements
      were prepared (except for the absence of footnotes and subject to year end
      audit
      adjustments) and fairly present the consolidated financial condition and
      operations of such Borrower at such dates and the consolidated results of their
      operations for the periods then ended.

     

    5.5.  Material
      Adverse Change.
      As of
      the date of this Agreement, since December 31, 2004, there has been
      no
      change in the business, Property, condition (financial or otherwise) or results
      of operations of such Borrower and its Subsidiaries (other than any Project
      Finance Subsidiary) which could reasonably be expected to have a Material
      Adverse Effect (a “Material Adverse Change”) with respect to such Borrower,
      except for the Disclosed Matters; provided,
      however,
      that
      neither (i) any ratings downgrade applicable to the Indebtedness of any Borrower

    or
      any of
      its Subsidiaries by Moody’s or S&P nor (ii) such Borrower’s or any of its
      Subsidiaries’ inability to place commercial paper in the capital markets, shall,
      in and of themselves, be deemed events constituting a Material Adverse
      Change.

     

    5.6.  Taxes.
      Such
      Borrower and its Subsidiaries have filed all United States federal tax returns
      and all other tax returns which are required to be filed and have paid all
      taxes
      due pursuant to said returns or pursuant to any assessment received by such
      Borrower or any of its Subsidiaries, except in respect of such taxes, if any,
      as
      are being contested in good faith and as to which adequate reserves have been
      provided in accordance with Agreement Accounting Principles and as to which
      no
      Lien exists (except as permitted by Section 6.13.2). The Internal Revenue
      Service has completed audits of the United States federal income tax returns
      filed by Union Electric for all periods through the calendar taxable year ending
      December 31, 1997 and by CIPSCO, Inc. for all periods through the calendar
      taxable year ending December 31, 1997. The Internal Revenue Service
      has not
      completed audits of the United States federal income tax returns filed by any
      Borrower and its Subsidiaries for subsequent periods. No claims have been,
      or
      are being, asserted with respect to such taxes that could reasonably be expected
      to result in a Material Adverse Effect with respect to such Borrower and no
      liens have been filed with respect to such taxes. The charges, accruals and
      reserves on the books of such Borrower and its Subsidiaries in respect of any
      taxes or other governmental charges are adequate.

     

    5.7.  Litigation
      and Contingent Obligations.
      On the
      date of this Agreement, other than the Disclosed Matters, there is no
      litigation, arbitration, governmental investigation, proceeding or inquiry
      pending or, to the knowledge of any of its officers, threatened against or
      affecting such Borrower or any of its Subsidiaries which could, if determined
      adversely to such Borrower or its Subsidiaries, reasonably be expected to have
      a
      Material Adverse Effect with respect to such Borrower or which seeks to prevent,
      enjoin or delay the making of any Loans to such Borrower. Other than any
      liability incident to any litigation, arbitration or proceeding which could
      not
      reasonably be expected to have a Material Adverse Effect with respect to such
      Borrower, such Borrower has no material contingent obligations not provided
      for
      or disclosed in the financial statements referred to in Section
      5.4.

     

    5.8.  Subsidiaries.
      Schedule 1 contains an accurate list of all Subsidiaries of such Borrower as
      of
      the date of this Agreement, setting forth their respective jurisdictions of
      organization and the percentage of their respective capital stock or other
      ownership interests owned by such Borrower or other Subsidiaries of such
      Borrower. All the issued and outstanding shares of capital stock or other
      ownership interests of such Subsidiaries have been (to the extent such concepts
      are relevant with respect to such ownership interests) duly authorized and
      issued and are fully paid and non-assessable.

     

    5.9.  ERISA.
      No
      ERISA Event has occurred or is reasonably expected to occur that, when taken
      together with all other ERISA Events that have occurred or are reasonably
      expected to occur, could reasonably be expected to result in a Material Adverse
      Effect with respect to such Borrower.

     

    5.10.  Accuracy
      of Information.
      The
      information, exhibits or reports with respect to such Borrower furnished to
      the
      Agent or to any Lender in connection with the negotiation of, or compliance
      with, the Loan Documents as of the date furnished do not contain any
      material

     

    
      
        
        

      

      
        45

        
          

        

      

      
        
        

      

    

    misstatement
      of fact or omit to state a material fact or any fact necessary to make the
      statements contained therein not misleading.

     

    5.11.  Regulation
      U.
      Neither
      such Borrower nor any of its Subsidiaries is engaged principally, or as one
      of
      its important activities, in the business of extending credit for the purpose,
      whether immediate, incidental or ultimate, of
      buying
      or carrying margin stock (as defined in Regulation U), and after applying the
      proceeds of each Advance, margin stock (as defined in Regulation U) will
      constitute less than 25% of the
      value of
      those assets of such Borrower and its Subsidiaries that are subject to any
      limitation on sale, pledge, or any other restriction hereunder.

     

    5.12.  Material
      Agreements.
      Neither
      such Borrower nor any of its Subsidiaries is a party to any agreement or
      instrument or subject to any charter or other corporate restriction which could
      reasonably be expected to have a Material Adverse Effect with respect to such
      Borrower as described in clauses (ii) and/or (iii) of the definition thereof.
      Neither such Borrower nor any of its Subsidiaries is in default in the
      performance, observance or fulfillment of any of the obligations, covenants
      or
      conditions contained in (i) any agreement or instrument to which it is a party,
      which default could reasonably be expected to have a Material Adverse Effect
      with respect to such Borrower or (ii) any agreement or instrument evidencing
      or
      governing Indebtedness, which default could be reasonably expected to have
      a
      Material Adverse Effect with respect to such Borrower.

     

    5.13.  Compliance
      With Laws.
      Except
      for the Disclosed Matters, such Borrower and its Subsidiaries have complied
      with
      all applicable statutes, rules, regulations, orders and restrictions of any
      domestic or foreign government or any instrumentality or agency thereof having
      jurisdiction over the conduct of their respective businesses or the ownership
      of
      their respective Property, non-compliance with which could reasonably be
      expected to result in a Material Adverse Effect with respect to such
      Borrower.

     

    5.14.  Ownership
      of Properties.
      On the
      date of this Agreement, such Borrower and its Subsidiaries have good title
      (except for minor defects in title that do not interfere with their ability
      to
      conduct their business as currently conducted or to utilize such properties
      for
      the intended purposes), free of all Liens other than those permitted by Section
      6.13, to all of the assets material to such Borrower’s business reflected in
      such Borrower’s most recent consolidated financial statements provided to the
      Agent, as owned by such Borrower and its Subsidiaries.

     

    5.15.  Plan
      Assets; Prohibited Transactions.
      Such
      Borrower is not an entity deemed to hold “plan assets” within the meaning of 29
      C.F.R. § 2510.3-101 of an employee benefit plan (as defined in Section 3(3) of
      ERISA) which is subject to Title I of ERISA or any plan (within the meaning
      of
      Section 4975 of the Code), and assuming the accuracy of the representations
      and
      warranties made in Section 9.12 and in any assignment made pursuant to Section
      12.3.3, neither the execution of this Agreement nor the making of Loans
      hereunder gives rise to a prohibited transaction within the meaning of Section
      406 of ERISA or Section 4975 of the Code.

     

    5.16.  Environmental
      Matters.
      In the
      ordinary course of its business, the officers of such Borrower consider the
      effect of Environmental Laws on the business of such Borrower and its

     

    
      
        
        

      

      
        46

        
          

        

      

      
        
        

      

    

     

    Subsidiaries,
      in the course of which they identify and evaluate potential risks and
      liabilities accruing to such Borrower due to Environmental Laws. On the basis
      of
      this consideration, such Borrower has concluded that, other than the Disclosed
      Matters, Environmental Laws cannot reasonably be expected to have a Material
      Adverse Effect with respect to such Borrower. Except for the Disclosed Matters,
      and except with respect to any other matters that, individually or in the
      aggregate, could not reasonably be expected to result in a Material Adverse
      Effect with respect to such Borrower, neither such Borrower nor any Subsidiary
      has received any notice to the effect that its operations are not in material
      compliance with any of the requirements of applicable Environmental Laws or
      are
      the subject of any federal or state investigation evaluating whether any
      remedial action is needed to respond to a release of any toxic or hazardous
      waste or substance into the environment.

     

    5.17.  Investment
      Company Act.
      Neither
      such Borrower nor any Subsidiary is an “investment company” or a company
“controlled” by an “investment company”, within the meaning of the Investment
      Company Act of 1940, as amended.

     

    5.18.  Public
      Utility Holding Company Act; Securities and Exchange Commission Authorization;
      Federal Energy Regulatory Commission.
      The
      Company is a “holding company”, and each of Union Electric, CIPS, CILCO and IP
      is a “public utility company”, as such terms are defined in the 1935 Act. The
      SEC, in accordance with the 1935 Act, has issued orders authorizing:

     

    (a)
        the
      incurrence by the Company or IP of short-term indebtedness for borrowed money
      in
      an aggregate principal amount not to exceed at any time $1,500,000,000 or
      $500,000,000, respectively, or (b) the issuance and sale by the Company of
      capital stock, preferred stock, certain other specified securities and long-term
      indebtedness for borrowed money in an aggregate principal amount not to exceed
      at any time $2,500,000,000, subject to, among other things, the condition that
      all such indebtedness be issued on or before June 30, 2007 and, in the
      case
      of short-term indebtedness, mature not later than 364 days thereafter, unless
      the 1935 Act is repealed or revised;
      and

     

    (b)
        the
      incurrence by Union Electric, CIPS or CILCO of short-term indebtedness for
      borrowed money in an aggregate principal amount not to exceed $1,000,000,000,
      $250,000,000 or $250,000,000, respectively, subject to, among other things,
      the
      condition that all such indebtedness be issued on or before March 31,
      2006
      and mature not later than 364 days thereafter, unless the 1935 Act is repealed
      or revised.

     

    Genco
      is
      certified by the FERC as an “exempt wholesale generator” under the Energy Policy
      Act of 1992. Genco is not a “public utility company” under the 1935 Act. The
      FERC, in accordance with the Federal Power Act, has issued an order authorizing
      the incurrence by Genco of short-term indebtedness for borrowed money in an
      aggregate principal amount not to exceed $300,000,000, subject to, among other
      things, the condition that all such indebtedness be issued on or before
      June 22, 2006 and mature not later than 364 days thereafter, unless
      the
      Federal Power Act is repealed or revised.

     

    Loans
      extended under this Agreement are short-term indebtedness for borrowed money
      and, in the case of the Company only, also long-term indebtedness for borrowed
      money within 

     

    
      
        
        

      

      
        47

        
          

        

      

      
        
        

      

    

     

    the
      meaning of the aforesaid orders of the SEC and the FERC. Unless such
      authorization is no longer required by applicable laws and regulations (and
      the
      Agent shall have received confirmation thereof reasonably satisfactory to it),
      additional authorization from the SEC or the FERC (or any governmental agency
      that succeeds to the authority of the SEC or the FERC), as applicable, will
      be
      necessary in order for (i) the Company or IP, after June 30,
      2007,
      (ii) Union Electric, CIPS or CILCO after March 31, 2006, and
      (iii) Genco, after June 22, 2006, to obtain any Advances under
      this
      Agreement or to incur or issue short-term indebtedness for borrowed money and,
      in the case of the Company, long-term indebtedness for borrowed money, in each
      case including, without limitation, Loans extended under this Agreement. Except
      for the aforesaid orders of the SEC and the FERC (as listed on Schedule 4
      hereto), on the Closing Date no regulatory authorizations, approvals, consents,
      registrations, declarations or filings are required in connection with the
      borrowings by, and issuances of Letters of Credit for the account of, each
      Borrower hereunder or the performance by each Borrower of the
      Obligations.

     

    5.19.  Insurance.
      Such
      Borrower maintains, and has caused each of its Subsidiaries to maintain, with
      financially sound and reputable insurance companies insurance on all its
      Property in such amounts, subject to such deductibles and self-insurance
      retentions and covering such properties and risks as are consistent with sound
      business practice.

     

    5.20.  No
      Default or Unmatured Default.
      No
      Default or Unmatured Default has occurred and is continuing with respect to
      such
      Borrower.

    COVENANTS

      the term of this Agreement, unless the Required Lenders shall otherwise consent

        48

        
          

        

      

      
        
        

      

    

    of
      such
      accountants, any such Default shall exist, stating the nature and status
      thereof.

     

    6.1.2

      each such period and consolidated statements of income and a statement of cash

      with the financial statements required under Sections 6.1.1 and 6.1.2, a
      compliance certificate in substantially the form of Exhibit B

such
      Borrower’s chief financial officer, controller or treasurer showing the
      calculations necessary to determine compliance with this Agreement and
      stating

            that
      no  Default or Unmatured Default with respect to such Borrower
      exists,
      or if any such Default or Unmatured Default exists, stating the nature and
      status thereof.

     

    6.1.4
        As
      soon
      as possible and in any event within 10 days after such Borrower knows that
      any
      ERISA Event has occurred that, alone or together with

    any
      other
      ERISA Events that have occurred, could reasonably be expected to result in
      liability of such Borrower, its Subsidiaries or any Commonly Controlled Entity

      aggregate amount exceeding
      $25,000,000, a statement, signed by the chief financial officer, controller

    6.1.5
        As
      soon
      as possible and in any event within 10 days after receipt by such Borrower,
      a
      copy of (a) any notice or claim to the effect that such Borrower 

               
      or
      any of its Subsidiaries is or may be liable to any Person as a result of the
      release by such Borrower, any of its Subsidiaries, or any other Person of any
      toxic or 

    hazardous
      waste or substance into the environment, and (b) any notice alleging any
      violation of any federal, state or local environmental, health or safety law
      or

    regulation
      by such Borrower or any of its Subsidiaries, which, in either case, could
      reasonably be expected to have a Material Adverse Effect with respect to such
      

    Borrower.

     

    6.1.6
        Promptly
      upon becoming aware thereof, notice of any upgrading or downgrading of the
      rating of such Borrower’s senior unsecured debt, 

                               
      commercial  paper or First Mortgage Bonds by Moody’s or
      S&P.

     

    6.1.7
        Such
      other information (including non-financial information) as the Agent or any
      Lender may from time to time reasonably request.

     

    6.2.  Use
      of
      Proceeds and Letters of Credit.
      Each
      Borrower will, and will cause each of its Subsidiaries to, use the proceeds
      of
      the Advances to repay any and all amounts outstanding 

     

    
      
        
        

      

      
        49

        
          

        

      

      
        
        

      

    

     

    under
      the
      Existing Credit Agreements and for general corporate purposes, including without
      limitation, for working capital, commercial paper liquidity support with respect
      to commercial paper issued by such Borrower or its Subsidiaries, to fund loans
      under and pursuant to the Money Pool Agreements, and to pay fees and expenses
      incurred in connection with this Agreement. Each Borrower shall use the proceeds
      of Advances in compliance with all applicable legal and regulatory requirements
      and any such use shall not result in a violation of any such requirements,
      including, without limitation, Regulation U and Regulation X, the Securities
      Act
      of 1933, as amended, and the Securities Exchange Act of 1934, as amended, and
      the regulations promulgated thereunder. Each Borrower shall use the Letters
      of
      Credit for general corporate purposes.

     

    6.3.  Notice
      of Default.
      Within
      five (5) Business Days after an Authorized Officer of any Borrower becomes
      aware
      thereof, such Borrower will, and will cause each Subsidiary to, give notice
      in
      writing to the Lenders of the occurrence of any Default or Unmatured Default
      and, unless otherwise reported to the SEC in such Borrower’s filings under the
      Securities Exchange Act of 1934, of any other development, financial or
      otherwise, which could reasonably be expected to have a Material Adverse Effect
      with respect to such Borrower.

     

    6.4.  Conduct
      of Business.
      Each
      Borrower will, and will cause each of its Subsidiaries to, carry on and conduct
      its business in substantially the same manner and in substantially the same
      fields of enterprise in which it is presently conducted or in a manner or fields
      of enterprise reasonably related thereto and do all things necessary to remain
      duly incorporated or organized, validly existing and (to the extent such concept
      applies to such entity) in good standing as a domestic corporation, partnership
      or limited liability company in its jurisdiction of incorporation or
      organization, as the case may be, and maintain all requisite authority to
      conduct its business in each jurisdiction in which its business is conducted.
      Notwithstanding the foregoing, no Borrower shall be prohibited from dissolving
      any Inactive Subsidiary or from the sale of any Subsidiary or assets pursuant
      to
      governmental or regulatory order or pursuant to Section 6.11.

     

    6.5.  Taxes.

      returns required by law and pay when due all taxes, assessments and governmental
      charges and levies upon it or its income, profits or Property, except those
      which are being contested in good faith by appropriate proceedings and with
      respect to which adequate reserves have been recorded in accordance with
      Agreement Accounting Principles.

     

    6.6.  Insurance.
      Each
      Borrower will, and will cause each of its Subsidiaries to, maintain with
      financially sound and reputable insurance companies insurance on all its
      Property in such amounts, subject to such deductibles and self-insurance
      retentions, and covering such risks as is consistent with sound business
      practice, and such Borrower will furnish to any Lender upon request full
      information as to the insurance carried.

     

    6.7.  Compliance
      with Laws; Securities and Exchange Commission and Federal Energy Regulatory
      Commission Authorization.
      

     

    (a)
       Each
      Borrower will, and will cause each of its Subsidiaries to, comply with all
      laws,

      interest in either of such Subsidiaries prior to such merger, and (iv) any
      Borrower or any Subsidiary may merge or consolidate with any Person other than

    7.9. Such
      Borrower or, in the case of the Company, any of its Subsidiaries (other than
      Project Finance Subsidiaries), shall fail within 45 days to pay, bond or
      otherwise discharge one or more (i) judgments or orders for the payment of
      money
      in excess of $50,000,000 (or the equivalent thereof in currencies other than

    7.11. Nonpayment
      by such Borrower or, in the case of the Company, any of its Subsidiaries (other
      than Project Finance Subsidiaries), of any Rate Management Obligation, in a

    ACCELERATION,
      WAIVERS, AMENDMENTS AND REMEDIES

     

    8.1.  Acceleration.
      If any
      Default described in Section 7.6 or 7.7 occurs with respect to a Borrower or,
      in
      the case of the Company, any of its Subsidiaries (other than any Project Finance
      Subsidiary), the obligations of the Lenders to make Loans and of the Issuing
      Banks to issue Letters of Credit hereunder to such Borrower shall automatically
      terminate and the Obligations of such Borrower shall immediately become due
      and
      payable without any election or action on the part of the Agent, any Issuing
      Bank or any Lender. If any other Default occurs with respect to a Borrower
      or,
      in the case of the Company, any of its Subsidiaries (other than any Project
      Finance Subsidiary to the extent excluded from such Default by the provisions
      of
      Article VII), the Required Lenders (or the Agent with the consent of the
      Required Lenders) may terminate or suspend the obligations of the Lenders to
      make Loans and of the Issuing Banks to issue Letters of Credit hereunder to
      such
      Borrower, or declare the Obligations to be due and payable, or both, whereupon
      the Obligations shall become immediately due and payable, without

    presentment,
      demand, protest or notice of any kind, all of which such Borrower hereby
      expressly waives.

     

    If,
      after
      acceleration of the maturity of the Obligations or termination of the
      obligations of the Lenders to make Loans and of the Issuing Banks to issue
      Letters of Credit hereunder as a result of any Default (other than any Default
      as described in Section 7.6 or 7.7 with respect to such Borrower) and before
      any
      judgment or decree for the payment of the Obligations due shall have been
      obtained or entered, the Required Lenders (in their sole discretion) shall
      so
      direct, the Agent shall, by notice to such Borrower, rescind and annul such
      acceleration and/or termination.

     

    8.2.  Amendments.
      Subject
      to the provisions of this Section 8.2, the Required Lenders (or the Agent with
      the consent in writing of the Required Lenders) and the Borrowers may enter
      into
      agreements supplemental hereto for the purpose of adding or modifying any
      provisions to the Loan Documents or changing in any manner the rights of the
      Lenders or the Borrowers hereunder or thereunder or waiving any Default
      hereunder or thereunder;
      provided, however,
      that no
      such supplemental agreement shall, without the consent of all of the Lenders
      (or, in the case of Section 8.2.2, all affected Lenders):

     

    8.2.1
        Extend
      the final maturity of any Revolving Loan or LC Disbursement or postpone any
      payment of principal of any Revolving Loan or LC Disbursement or forgive all
      or
      any portion of the principal amount thereof, or reduce the rate or extend the
      time of payment of interest or fees thereon (other than a waiver of the
      application of the default rate of interest pursuant to Section 2.14
      hereof).

     

    8.2.2
        Extend
      the final maturity of any Competitive Loan or postpone any regularly scheduled
      payment of principal of any Competitive Loan or forgive all or any portion
      of
      the principal amount thereof, or reduce the rate or extend the time of payment
      of interest or fees thereon (other than a waiver of the application of the
      default rate of interest pursuant to Section 2.14 hereof). 

     

    8.2.3
        Waive
      any
      condition set forth in Section 4.2, reduce the percentage specified in the
      definition of Required Lenders or any other percentage of Lenders specified
      to
      be the Pro Rata Share in this Agreement to act on specified matters or amend
      the
      definition of “Pro Rata Share”.

     

    8.2.4
        Other
      than as expressly permitted by the terms of Section 2.23, extend the Commitment
      Termination Date or the Maturity Date applicable to any Borrower, or reduce
      the
      amount or extend the payment date for, the mandatory payments required under
      Section 2.2, or increase the amount of the Commitment of any Lender hereunder
      or
      change the definition of Subsidiary Sublimit hereunder, or permit any Borrower
      to assign its rights or obligations under this Agreement or change Section
      2.15
      or 2.8.4 in a manner that would alter the pro rata sharing of payments or
      reduction of commitments required thereby.

     

    8.2.5
        Amend
      this Section 8.2.

    No
      amendment of any provision of this Agreement relating to the Agent, any Issuing
      Bank or the Swingline Lender shall be effective without the written consent
      of
      the Agent, such Issuing Bank or the Swingline Lender, as the case may be. The
      Agent may waive payment of the fee required under Section 12.3.3 without
      obtaining the consent of any other party to this Agreement. Notwithstanding
      the
      foregoing, any provision of this Agreement may be amended by an agreement in
      writing entered into by the applicable Borrower, the Required Lenders and the
      Agent if (i) by the terms of such agreement any remaining Commitment of each
      Lender not consenting to the amendment provided for therein shall terminate
      upon
      the effectiveness of such amendment and (ii) at the time such amendment becomes
      effective, each Lender not consenting thereto receives payment in full of the
      principal of and interest accrued on each Advance made by it and all other
      amounts owing to it or accrued for its account under this
      Agreement.

     

    8.3.  Preservation
      of Rights.
      No
      delay or omission of the Lenders, the Agent or the Issuing Banks to exercise
      any
      right under the Loan Documents shall impair such right or be construed to be
      a
      waiver of any Default or an acquiescence therein, and the making of a Credit
      Extension notwithstanding the existence of a Default or Unmatured Default or
      the
      inability of a Borrower to satisfy the conditions precedent to such Credit
      Extension shall not constitute any waiver or acquiescence. Any single or partial
      exercise of any such right shall not preclude other or further exercise thereof
      or the exercise of any other right, and no waiver, amendment or other variation
      of the terms, conditions or provisions of the Loan Documents whatsoever shall
      be
      valid unless in writing signed by, or by the Agent with the consent of, the
      requisite number of Lenders required pursuant to Section 8.2, and then only
      to
      the extent in such writing specifically set forth. All remedies contained in
      the
      Loan Documents or by law afforded shall be cumulative and all shall be available
      to the Agent, the Issuing Banks and the Lenders until all of the Obligations
      have been paid in full.

    GENERAL
      PROVISIONS

     

    9.1.  Survival
      of Representations.
      All
      representations and warranties of the Borrowers contained in this Agreement
      shall survive the making of the Credit Extensions herein
      contemplated.

     

    9.2.  Governmental
      Regulation.
      Anything contained in this Agreement to the contrary notwithstanding, no Lender
      shall be obligated to extend credit to any Borrower in violation of any
      limitation or prohibition provided by any applicable statute or
      regulation.

     

    9.3.  Headings.
      Section
      headings in the Loan Documents are for convenience of reference only, and shall
      not govern the interpretation of any of the provisions of the Loan
      Documents.

     

    9.4.  Entire
      Agreement.
      The
      Loan Documents embody the entire agreement and understanding among the Agent
      and
      the Lenders, and between the Agent and the Lenders on one hand, and the
      Borrowers individually on the other hand, and supersede all prior agreements
      and
      understandings among and between such parties, as the case may be, relating
      to
      the subject

    matter
      thereof other than those contained in the fee letter described in Section 10.13
      which shall survive and remain in full force and effect during the term of
      this
      Agreement.

     

    9.5.  Several
      Obligations; Benefits of this Agreement.
      The
      respective obligations of the Lenders and the Issuing Banks hereunder are
      several and not joint and no Lender or Issuing Bank shall be the partner or
      agent of any other (except to the extent to which the Agent is authorized to
      act
      as such). The failure of any Lender or any Issuing Bank to perform any of its
      obligations hereunder shall not relieve any other Lender or any Issuing Bank
      from any of its obligations hereunder. This Agreement shall not be construed
      so
      as to confer any right or benefit upon any Person other than the parties to
      this
      Agreement and their respective successors and assigns, provided,
      however,
      that the
      parties hereto expressly agree that each Arranger shall enjoy the benefits
      of
      the provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set
      forth therein and shall have the right to enforce such provisions on its own
      behalf and in its own name to the same extent as if it were a party to this
      Agreement (it being acknowledged that Section 9.6 may be enforced against any
      Borrower only to the extent of the amounts for which such Borrower is liable
      under the terms of such Section).

     

    9.6.  Expenses;
      Indemnification.
      (i)
      The
      Company shall reimburse the Agent and each Arranger for any reasonable costs,

        except
        to the extent that they have resulted, as determined in a final non-appealable
        judgment by a court of competent jurisdiction, from the gross negligence
        or
        willful misconduct of the party seeking indemnification.

       

    

     

    
      	(iii)  	
              Each
                amount payable under paragraph (ii) of this Section shall be an obligation
                of, and shall be discharged by (a) to the extent arising out of acts,
                events and circumstances related to a particular Borrower, such Borrower
                and (b) otherwise, all the Borrowers, with each Borrower being

                herein,
                of the entire amount of the Commitments in the form of borrowings
                by and

                pay any amount owed by it under clause (b) of this paragraph (iii)
                after a
                demand shall have been made by the Person to which such amount is
                owed,
                the Company shall promptly pay such amount (the Company hereby irrevocably
                waiving any defenses that might otherwise be available to it as a
                guarantor of the obligations of any Borrowing Subsidiary under this
                Section).

            

    

     

    
      	(iv)  	
              To
                the extent that the Borrowers fail to pay any amount required to

                agrees to pay to the Agent, such Arranger, such Issuing Bank or the
                Swingline Lender, as the case may be, such Lender’s Pro Rata Share
                (determined as of the time that the applicable unreimbursed expense
                or
                indemnity payment is sought) 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 Agent, such Arranger, such Issuing Bank or the
                Swingline Lender in its capacity as
                such.

            

    

     

    
      	(v)  	
              The
                obligations of the Borrowers under this Section 9.6 shall survive
                the
                termination of this Agreement and, as to each Borrower, the Maturity
                Date
                applicable to such Borrower. 

            

    

     

    9.7.  Numbers
      of Documents.
      All
      statements, notices, closing documents, and requests hereunder shall be
      furnished to the Agent with sufficient counterparts so that the Agent may
      furnish one to each of the Lenders, to the extent that the Agent deems
      necessary.

     

    9.8.  Accounting.
      Except
      as provided to the contrary herein, all accounting terms used in the calculation
      of any financial covenant or test shall be interpreted and all accounting
      determinations hereunder in the calculation of any financial covenant or test
      shall be made in accordance with Agreement Accounting Principles. If any changes
      in generally accepted accounting principles are hereafter required or permitted
      and are adopted by any Borrower or any of its Subsidiaries with the agreement
      of
      its independent certified public accountants and such changes result in a change
      in the method of calculation of any of the financial covenants, tests,
      restrictions or standards herein or in the related definitions or terms used
      therein (“Accounting

    Changes”),
      the parties hereto agree, at such Borrower’s request, to enter into
      negotiations, in good faith, in order to amend such provisions in a credit
      neutral manner so as to reflect equitably such changes with the desired result
      that the criteria for evaluating such Borrower’s and its Subsidiaries’ financial
      condition shall be the same after such changes as if such changes had not been
      made; provided,
      however,
      until
      such provisions are amended in a manner reasonably satisfactory to the Agent
      and
      the Required Lenders, no Accounting Change shall be given effect in such
      calculations. In the event such amendment is entered into, all references in
      this Agreement to Agreement Accounting Principles shall mean generally accepted
      accounting principles as of the date of such amendment. Notwithstanding the
      foregoing, all financial statements to be delivered by such Borrower pursuant
      to
      Section 6.1 shall be prepared in accordance with generally accepted accounting
      principles in effect at such time.

     

    9.9.  Severability
      of Provisions.
      Any
      provision in any Loan Document that is held to be inoperative, unenforceable
      or
      invalid in any jurisdiction shall, as to that jurisdiction, be inoperative,
      unenforceable or invalid without affecting the remaining provisions in that
      jurisdiction or the operation, enforceability or validity of that provision
      in
      any other jurisdiction, and to this end the provisions of all Loan Documents
      are
      declared to be severable.

     

    9.10.  Nonliability.
      The
      relationship between the Borrowers individually on the one hand and the Lenders
      and the Agent on the other hand shall be solely that of borrower and lender.
      None of the Agent, any Arranger, any Issuing Bank or any Lender shall have
      any
      fiduciary responsibilities to the Borrowers. None of the Agent, any Arranger,
      any Issuing Bank or any Lender undertakes any responsibility to the Borrowers
      to
      review or inform the Borrowers of any matter in connection with any phase of
      the
      Borrowers’ businesses or operations. The Borrowers agree that none of the Agent,
      any Arranger, any Issuing Bank or any Lender shall have liability to the
      Borrowers (whether sounding in tort, contract or otherwise) for losses suffered
      by the Borrowers in connection with, arising out of, or in any way related
      to,
      the transactions contemplated and the relationship established by the Loan
      Documents, or any act, omission or event occurring in connection therewith,
      unless it is determined in a final non-appealable judgment by a court of
      competent jurisdiction that such losses resulted from the gross negligence
      or
      willful misconduct of the party from which recovery is sought. None of the
      Borrowers, the Agent, any Arranger, any Issuing Bank or any Lender shall have
      any liability with respect to, and each of the Agent, each Arranger, each
      Issuing Bank, each Lender and each Borrower hereby waives, releases and agrees
      not to sue for, any special, indirect, consequential or punitive damages
      suffered by it in connection with, arising out of, or in any way related to
      the
      Loan Documents or the transactions contemplated thereby.

     

    9.11.  Confidentiality.
      Each
      Lender and each Issuing Bank agrees to hold any confidential information which
      it may receive from any Borrower pursuant to this Agreement in confidence,
      except for disclosure (i) to its Affiliates and to other Borrowers, Lenders
      or
      Issuing Banks and their respective Affiliates, for use solely in connection
      with
      the transactions contemplated hereby, (ii) to legal counsel, accountants, and
      other professional advisors to such Lender or Issuing Bank or to a Transferee,
      in each case which have been informed as to the confidential nature of such
      information, for use solely in connection with the transactions contemplated
      hereby, (iii) to regulatory officials having jurisdiction over it or its
      Affiliates, (iv) to any Person as required by law, regulation, or legal process,
      (v) to any Person in connection with any legal proceeding to which such Lender
      or Issuing Bank is a party, (vi) to such Lender’s

    or
      Issuing Bank’s direct or indirect contractual counterparties in swap agreements
      or to legal counsel, accountants and other professional advisors to such
      counterparties, in each case which have been informed as to the confidential
      nature of such information, (vii) as permitted by Section 12.4 and (viii) to
      rating agencies if requested or required by such agencies in connection with
      a

    9.12.  Lenders
      Not Utilizing Plan Assets.
      Each
      Lender and Designated Lender represents and warrants that none of the
      consideration used by such Lender or Designated Lender to make its Loans
      constitutes for any purpose of ERISA or Section 4975 of the Code assets of
      any
“plan” as defined in Section 3(3) of ERISA or Section 4975 of the Code and the
      rights and interests of such Lender or Designated Lender in and under the Loan
      Documents shall not constitute such “plan assets” under ERISA.

     

    9.13.  Nonreliance.
      Each
      Lender hereby represents that it is not relying on or looking to any margin
      stock (as defined in Regulation U) as collateral in the extension or maintenance
      of the credit provided for herein.

     

    9.14.  Disclosure.
      The
      Borrowers and each Lender and each Issuing Bank hereby acknowledge and agree

      hold investments in, make other loans to or have other relationships with the
      Borrowers and their Affiliates.

      Patriot Act.
      Each
      Lender and each Issuing Bank hereby notifies the Borrowers that pursuant to
      the
      requirements of the USA Patriot Act, it is required to obtain, verify and record
      information that identifies the Borrowers, which information includes the names
      and addresses of the Borrowers and other information that will allow such Lender
      to identify the Borrowers in accordance with its requirements. The Borrowers
      shall promptly following a request by the Administrative Agent or any Lender,
      provide all documentation and other information that the Administrative Agent
      or
      such Lender reasonably requests in order to comply with its ongoing obligations
      under applicable “know your customer” and anti-money laundering rules and
      regulations including the USA Patriot Act.

    10.1.  Appointment;
      Nature of Relationship.
      JPMCB
      is hereby appointed by each of the Lenders and each of the Issuing Banks as
      its
      contractual representative (herein referred to as the “Agent”) hereunder and
      under each other Loan Document, and each of the Lenders and the each of the
      Issuing Banks irrevocably authorizes the Agent to act as the contractual
      representative of such Lender and such Issuing Bank with the rights and duties
      expressly set forth herein and in the other Loan Documents. The Agent agrees
      to
      act as such contractual representative upon the express conditions contained
      in
      this Article X. Notwithstanding the use of the defined term “Agent,” it is
      expressly understood and agreed that the Agent shall not have any fiduciary
      responsibilities to any Lender or any Issuing Bank by reason of this Agreement
      or any other

      Document and that the Agent is merely acting as the contractual representative
      of the Lenders and the Issuing Banks with only those duties as are expressly
      set
      forth in this Agreement and the other Loan Documents. In its capacity as the
      Lenders’ and the Issuing Banks’ contractual representative, the Agent (i) does
      not hereby assume any fiduciary duties to any of the Lenders or the Issuing
      Banks, (ii) is a “representative” of the Lenders and the Issuing Banks within
      the meaning of the term “secured party” as defined in the New York Uniform
      Commercial Code and (iii) is acting as an independent contractor, the rights
      and
      duties of which are limited to those expressly set forth in this Agreement
      and
      the other Loan Documents. Each of the Lenders and the Issuing Banks hereby
      agrees to assert no claim against the Agent on any agency theory or any other
      theory of liability for breach of fiduciary duty, all of which claims each
      Lender hereby waives.

     

    10.2.  Powers.
      The
      Agent shall have and may exercise such powers under the Loan Documents as are
      specifically delegated to the Agent by the terms of each thereof, together
      with
      such powers as are reasonably incidental thereto. The Agent shall have no
      implied duties or fiduciary duties to the Lenders or the Issuing Banks, or
      any
      obligation to the Lenders or the Issuing Banks to take any action thereunder
      except any action specifically provided by the Loan Documents to be taken by
      the
      Agent.

     

    10.3.  General
      Immunity.
      Neither
      the Agent nor any of its directors, officers, agents or employees shall be
      liable to the Borrowers, the Lenders or any Lender or any Issuing Bank for
      any
      action taken or omitted to be taken by it or them hereunder or under any other
      Loan Document or in connection herewith or therewith except to the extent such
      action or inaction is determined in a final, non-appealable judgment by a court
      of competent jurisdiction to have arisen from the gross negligence or willful
      misconduct of such Person.

     

    10.4.  No
      Responsibility for Loans, Recitals, etc.
      Neither
      the Agent nor any of its directors, officers, agents or employees shall be
      responsible for or have any duty to ascertain, inquire into, or verify (a)
      any
      statement, warranty or representation made in connection with any Loan Document
      or any borrowing hereunder; (b) the performance or observance of any of the
      covenants or agreements of any obligor under any Loan Document, including,
      without limitation, any agreement by an obligor to furnish information directly
      to each Lender and each Issuing Bank; (c) the satisfaction of any condition
      specified in Article IV, except receipt of items required to be delivered solely
      to the Agent; (d) the existence or possible existence of any Default or
      Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency
      or genuineness of any Loan Document or any other instrument or writing furnished
      in connection therewith; (f) the value, sufficiency, creation, perfection or
      priority of any Lien in any collateral security; or (g) the financial condition
      of the Borrowers or any guarantor of any of the Obligations or of any of the
      Borrowers’ or any such guarantor’s respective Subsidiaries. The Agent shall have
      no duty to disclose to the Lenders or the Issuing Banks information that is
      not
      required to be furnished by the Borrowers to the Agent at such time, but is
      voluntarily furnished by the Borrowers to the Agent (either in its capacity
      as
      Agent or in its individual capacity).

     

    10.5.  Action
      on Instructions of Lenders.
      The
      Agent shall in all cases be fully protected in acting, or in refraining from
      acting, hereunder and under any other Loan Document in accordance with written
      instructions signed by the Required Lenders (or all of the Lenders in the event
      that and to the extent that this Agreement expressly requires such), and such
      instructions

    and
      any
      action taken or failure to act pursuant thereto shall be binding on all of
      the
      Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty
      to
      take any discretionary action permitted to be taken by it pursuant to the
      provisions of this Agreement or any other Loan Document unless it shall be
      requested in writing to do so by the Required Lenders (or all of the Lenders
      in
      the event that and to the extent that this Agreement expressly requires such).
      The Agent shall be fully justified in failing or refusing to take any action
      hereunder and under any other Loan Document unless it shall first be indemnified
      to its satisfaction in writing by the Lenders pro rata against any and all
      liability, cost and expense that it may incur by reason of taking or continuing
      to take any such action.

     

    10.6.  Employment
      of Agents and Counsel.
      The
      Agent may execute any of its duties as Agent hereunder and under any other
      Loan
      Document by or through employees, agents, and attorneys-in-fact and shall not
      be
      answerable to the Lenders or the Issuing Banks, except as to money or securities
      received by it or its authorized agents, for the default or misconduct of any
      such agents or attorneys-in-fact selected by it with reasonable care. The Agent
      shall be entitled to advice of counsel concerning the contractual arrangement
      between the Agent and the Lenders and the Issuing Banks and all matters
      pertaining to the Agent’s duties hereunder and under any other Loan
      Document.

     

    10.7.  Reliance
      on Documents; Counsel.
      The
      Agent shall be entitled to rely upon any Note, notice, consent, certificate,
      affidavit, letter, telegram, statement, paper or document believed by it to
      be
      genuine and correct and to have been signed or sent by the proper person or
      persons, and, in respect to legal matters, upon the opinion of counsel selected
      by the Agent, which counsel may be employees of the Agent.

     

    10.8.  Agent’s
      Reimbursement and Indemnification.
      The
      Lenders agree to reimburse and indemnify the Agent ratably in proportion to
      the
      their Pro Rata Shares of the Aggregate Commitment (or, if the Aggregate
      Commitment has been terminated, of the Aggregate Outstanding Credit Exposure)
      (determined as of the date of any such request by the Agent) (i) for any amounts
      not reimbursed by the Borrowers for which the Agent is entitled to reimbursement
      by the Borrowers under the Loan Documents, (ii) to the extent not paid by the
      Borrowers, for any other expenses incurred by the Agent on behalf of the Lenders
      or the Issuing Banks, in connection with the preparation, execution, delivery,
      administration and enforcement of the Loan Documents (including, without
      limitation, for any expenses incurred by the Agent in connection with any
      dispute between the Agent and any Lender or between two or more of the Lenders
      or Issuing Banks) and (iii) to the extent not paid by the Borrowers, for any
      liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
      costs, expenses or disbursements of any kind and nature whatsoever which may
      be
      imposed on, incurred by or asserted against the Agent in any way relating to
      or
      arising out of the Loan Documents or any other document delivered in connection
      therewith or the transactions contemplated thereby (including, without
      limitation, for any such amounts incurred by or asserted against the Agent
      in
      connection with any dispute between the Agent and any Lender or between two
      or
      more of the Lenders or Issuing Banks), or the enforcement of any of the terms
      of
      the Loan Documents or of any such other documents, provided
      that (i)
      no Lender shall be liable for any of the foregoing to the extent any of the
      foregoing is found in a final, non-appealable judgment by a court of competent
      jurisdiction to have resulted from the gross negligence or willful misconduct
      of
      the Agent, (ii) any indemnification required pursuant to Section 3.5(vii) shall,
      notwithstanding the provisions of this

    Section
      10.8, be paid by the relevant Lender in accordance with the provisions thereof
      and (iii) the Agent shall reimburse the Lenders for any amounts the
      Lenders
      have paid to the extent such amounts are subsequently recovered from the
      Borrowers. The obligations of the Lenders under this Section 10.8 shall survive
      payment of the Obligations, termination and expiration of the Letters of Credit
      and termination of this Agreement.

     

    10.9.  Notice
      of Default.
      The
      Agent shall not be deemed to have knowledge or notice of the occurrence of
      any
      Default or Unmatured Default hereunder unless the Agent has received written
      notice from a Lender or a Borrower referring to this Agreement describing such
      Default or Unmatured Default and stating that such notice is a “notice of
      default”. In the event that the Agent receives such a notice, the Agent shall
      give prompt notice thereof to the Lenders and the Issuing Banks.

     

    10.10.  Rights
      as a Lender.
      In the
      event the Agent is a Lender or an Issuing Bank, the Agent shall have the same
      rights and powers hereunder and under any other Loan Document with respect
      to
      its Commitment and its Credit Extensions as any Lender or any Issuing Bank
      and
      may exercise the same as though it were not the Agent, and the term “Lender” or
“Lenders” or “Issuing Bank” shall, at any time when the Agent is a Lender or an
      Issuing Bank, unless the context otherwise indicates, include the Agent in
      its
      individual capacity. The Agent and its Affiliates may accept deposits from,
      lend
      money to, and generally engage in any kind of trust, debt, equity or other
      transaction, in addition to those contemplated by this Agreement or any other
      Loan Document, with each Borrower or any of its Subsidiaries in which such
      Borrower or such Subsidiary is not restricted hereby from engaging with any
      other Person. The Agent, in its individual capacity, is not obligated to remain
      a Lender.

     

    10.11.  Independent
      Credit Decision.
      Each
      Lender and each Issuing Bank acknowledges that it has, independently and without
      reliance upon the Agent, any Arranger or any other Lender or any other Issuing
      Bank and based on the financial statements prepared by the Borrowers and such
      other documents and information as it has deemed appropriate, made its own
      credit analysis and decision to enter into this Agreement and the other Loan
      Documents. Each Lender and each Issuing Bank also acknowledges that it will,
      independently and without reliance upon the Agent, any Arranger or any other
      Lender and based on such documents and information as it shall deem appropriate
      at the time, continue to make its own credit decisions in taking or not taking
      action under this Agreement and the other Loan Documents.

     

    10.12.  Successor
      Agent.
      The
      Agent may resign at any time by giving written notice thereof to the Lenders,
      the Issuing Banks and the Borrowers, such resignation to be effective upon
      the
      appointment of a successor Agent or, if no successor Agent has been appointed,
      forty-five days after the retiring Agent gives notice of its intention to
      resign. The Agent may be removed at any time with or without cause by written
      notice received by the Agent from the Required Lenders, such removal to be
      effective on the date specified by the Required Lenders. Upon any such
      resignation or removal, the Required Lenders, with the consent of the Borrowers
      (which consent shall not be unreasonably withheld or delayed; provided
      that
      such consent shall not be required in the event and continuation of a Default),
      shall have the right to appoint, on behalf of the Borrowers and the Lenders,
      a
      successor Agent. If no successor Agent shall have been so appointed by the
      Required Lenders or consented to by the Borrowers within thirty days after
      the
      resigning Agent’s giving notice of its intention to resign, then the resigning
      Agent may

     

     

    
      
        
        

      

      
        68

        
          

        

      

      
        
        

      

    

     

     appoint,
      on behalf of the Borrowers and the Lenders, a successor Agent. Notwithstanding
      the previous sentence, the Agent may at any time without the consent of the
      Borrowers or any Lender or any Issuing Bank, appoint any of its Affiliates
      which
      is a commercial bank as a successor Agent hereunder. If the Agent has resigned
      or been removed and no successor Agent has been appointed, the Lenders may
      perform all the duties of the Agent hereunder and the Borrowers shall make
      all
      payments in respect of the Obligations to the applicable Lender and for all
      other purposes shall deal directly with the Lenders. No successor Agent shall
      be
      deemed to be appointed hereunder until such successor Agent has accepted the
      appointment. Any such successor Agent shall be a commercial bank having capital
      and retained earnings of at least $100,000,000. Upon the acceptance of any
      appointment as Agent hereunder by a successor Agent, such successor Agent shall
      thereupon succeed to and become vested with all the rights, powers, privileges
      and duties of the resigning or removed Agent. Upon the effectiveness of the
      resignation or removal of the Agent, the resigning or removed Agent shall be
      discharged from its duties and obligations hereunder and under the Loan
      Documents. After the effectiveness of the resignation or removal of an Agent,
      the provisions of this Article X shall continue in effect for the benefit of
      such Agent in respect of any actions taken or omitted to be taken by it while
      it
      was acting as the Agent hereunder and under the other Loan Documents. In the
      event that there is a successor to the Agent by merger, or the Agent assigns
      its
      duties and obligations to an Affiliate pursuant to this Section 10.12, then
      the
      term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate
      or other analogous rate of the new Agent.

     

    10.13.  Agent
      and Arranger Fees.
      The
      Company agrees to pay to the Agent and each Arranger, for their respective
      accounts, the agent and arranger fees agreed to by the Borrowers, the Agent
      and
      the Arrangers pursuant to the letter agreements dated June 13, 2005,
      or as
      otherwise agreed from time to time.

     

    10.14.  Delegation
      to Affiliates.
      The
      Borrowers, the Lenders and the Issuing Banks agree that the Agent may delegate
      any of its duties under this Agreement to any of its Affiliates. Any such
      Affiliate (and such Affiliate’s directors, officers, agents and employees) which
      performs duties in connection with this Agreement shall be entitled to the
      same
      benefits of the indemnification, waiver and other protective provisions to
      which
      the Agent is entitled under Articles IX and X.

     

    10.15.  Syndication
      Agent and Documentation Agents.
      The
      Lender identified in this Agreement as the “Syndication Agent” and the Lenders
      identified in this Agreement as the “Documentation Agents” shall have no right,
      power, obligation, liability, responsibility or duty under this Agreement other
      than those applicable to all Lenders as such. Without limiting the foregoing,
      such Lenders shall not have or be deemed to have a fiduciary relationship with
      any other Lender. Each Lender hereby makes the same acknowledgements with
      respect to such Lenders as it makes with respect to the Agent in Section
      10.11.

    SETOFF;
      RATABLE PAYMENTS

     

    11.1.  Setoff.
      In
      addition to, and without limitation of, any rights of the Lenders under
      applicable law, if a Borrower becomes insolvent, however evidenced, or any
      Default occurs with

    respect
      to a Borrower, any and all deposits (including all account balances, whether
      provisional or final and whether or not collected or available) and any other
      Indebtedness at any time held or owing by any Lender (including the Swingline
      Lender) or any Affiliate of any Lender or any Issuing Bank to or for the credit
      or account of such Borrower may be offset and applied toward the payment of
      the
      Obligations owing by such Borrower to such Lender or such Issuing Bank, whether
      or not the Obligations, or any part thereof, shall then be due.

     

    11.2.  Ratable
      Payments.
      If any
      Lender, whether by setoff or otherwise, has payment made to it upon its
      Revolving Credit Exposure (other than payments received pursuant to Section
      3.1,
      3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender,
      such Lender agrees, promptly upon demand, to purchase a participation in the
      Aggregate Revolving Credit Exposure held by the other Lenders so that after
      such
      purchase each Lender will hold its Pro Rata Share of the Aggregate Revolving
      Credit Exposure. If any Lender, whether in connection with setoff or amounts
      which might be subject to setoff or otherwise, receives collateral or other
      protection for its Obligations or such amounts which may be subject to setoff,
      such Lender agrees, promptly upon demand, to take such action necessary such
      that all Lenders share in the benefits of such collateral ratably in proportion
      to their respective Pro Rata Shares of the Aggregate Revolving Credit Exposure.
      In case any such payment is disturbed by legal process, or otherwise,
      appropriate further adjustments shall be made.

    12.1.1
         Successors
      and Assigns.
      The
      terms and provisions of the Loan Documents shall be binding upon and inure
      to
      the benefit of the Borrowers, the Agent, the Issuing Banks and the Lenders
      and
      their respective successors and assigns permitted hereby, except that (i) the
      Borrowers shall not have the right to assign their rights or obligations under
      the Loan Documents without the prior written consent of the Agent, each Lender
      and each Issuing Bank, (ii) any assignment by any Lender must be made in
      compliance with Section 12.3, and (iii) any transfer by Participants must be
      made in compliance with Section 12.2. Any attempted assignment or transfer
      by
      any party not made in compliance with this Section 12.1 shall be null and void,
      unless such attempted assignment or transfer is treated as a participation
      in
      accordance with Section 12.3.2. The parties to this Agreement acknowledge that
      clause (ii) of this Section 12.1 relates only to absolute assignments and this
      Section 12.1 does not prohibit assignments creating security interests,
      including, without limitation, (x) any pledge or assignment by any Lender of
      all
      or any portion of its rights under this Agreement and any Note to a Federal
      Reserve Bank, (y) in the case of a Lender which is a Fund, any pledge or
      assignment of all or any portion of its rights under this Agreement and any
      Note
      to its trustee in support of its obligations to its trustee or (z) any pledge
      or

      Agreement and any Note to direct or indirect contractual counterparties in

    relating
      to the Loans; provided, however,
      that no
      such pledge or assignment creating a security interest shall release the
      transferor Lender from its obligations  hereunder unless and
      until the
      parties thereto have complied with the provisions of Section 12.3. The Agent
      may
      treat the Person which made any Loan or which holds any Note as the owner
      thereof for all purposes hereof unless and until such Person complies with
      Section 12.3; provided, however,
      that the
      Agent may in its discretion (but shall not be required to) follow instructions
      from the Person which made any Loan or which holds any Note to direct payments
      relating to such Loan or Note to another Person. Any assignee of the rights
      to
      any Loan or any Note agrees by acceptance of such assignment to be bound by
      all
      the terms and provisions of the Loan Documents. Any request, authority or
      consent of any Person, who at the time of making such request or giving such
      authority or consent is the owner of the rights to any Loan (whether or not
      a
      Note has been issued in evidence thereof), shall be conclusive and binding
      on
      any subsequent holder or assignee of the rights to such Loan.

     

    12.1.2
        Designated
      Lenders.
      

     

    
      	(i)  	
              Subject
                to the terms and conditions set forth in this Section 12.1.2, any
                Lender
                may from time to time elect to designate an Eligible Designee to
                provide
                all or any part of the Loans to be made by such Lender pursuant to
                this
                Agreement; provided
                that the designation of an Eligible Designee by any Lender for purposes
                of
                this Section 12.1.2 shall be subject to the approval of the Agent
                (which
                consent shall not be unreasonably withheld or delayed). Upon the
                execution
                by the parties to each such designation of an agreement in the form
                of
                Exhibit F hereto (a “Designation Agreement”) and the acceptance thereof by
                the Agent, the Eligible Designee shall become a Designated Lender
                for
                purposes of this Agreement. The Designating Lender shall thereafter
                have
                the right to permit the Designated Lender to provide all or a portion
                of
                the Loans to be made by the Designating Lender pursuant to the terms
                of
                this Agreement and the making of such Loans or portion thereof shall
                satisfy the obligations of the Designating Lender to the same extent,
                and
                as if, such Loan was made by the Designating Lender. As to any Loan
                made
                by it, each Designated Lender shall have all the rights a Lender
                making
                such Loan would have under this Agreement and otherwise; provided,
                (x) that all voting rights under this Agreement shall be exercised
                solely
                by the Designating Lender, (y) each Designating Lender shall remain
                solely
                responsible to the other parties hereto for its obligations under
                this
                Agreement, including the obligations of a Lender in respect of Loans
                made
                by its Designated Lender and (z) no Designated Lender shall be entitled
                to
                reimbursement under Article
                III
                hereof for any amount which would exceed the amount that would have
                been
                payable by the Borrowers to the Lender from which the Designated
                Lender
                obtained any interests hereunder. No additional Notes shall be required
                with respect to Loans provided by a Designated Lender; provided,
                however,
                to the extent any Designated Lender shall advance funds, the Designating
                Lender shall be deemed to hold the Notes in its possession as an
                agent for
                such Designated Lender to the extent of the Loan funded by such Designated
                Lender. Such Designating Lender shall act as

      administrative
        agent for its Designated Lender and give and receive notices and communications
        hereunder. Any payments for the account of any Designated Lender shall be
        paid
        to its Designating Lender as administrative agent for such Designated Lender
        and
        neither the Borrowers nor the Agent shall be responsible for any Designating
        Lender’s application of such payments. In addition, any Designated Lender may
        (1) with notice to, but without the consent of, the Borrowers or the Agent,
        assign all or portions of its interests in any Loans to its Designating Lender
        or to any financial institution consented to by the Agent providing liquidity
        and/or credit facilities to or for the account of such Designated Lender
        and (2)
        subject to advising any such Person that such information is to be treated
        as
        confidential in accordance with Section 9.11, disclose on a confidential
        basis
        any non-public information relating to its Loans to any rating agency,
        commercial paper dealer or provider of any guarantee, surety or credit or
        liquidity enhancement to such Designated Lender.

       

    

     

    
      	(ii)  	
              Each
                party to this Agreement hereby agrees that it shall not institute
                against,
                or join any other Person in instituting against, any Designated Lender
                any
                bankruptcy, reorganization, arrangement, insolvency or liquidation
                proceeding or other proceedings under any federal or state bankruptcy
                or
                similar law for one year and a day after the payment in full of all
                outstanding senior indebtedness of any Designated Lender. This Section
                12.1.2 shall survive the termination of this
                Agreement.

            

    

     

    12.2.  Participations.

     

    12.2.1
        Permitted
      Participants; Effect.
      Any
      Lender may at any time sell to one or more banks or other entities
      (“Participants”) participating interests in any Outstanding Credit Exposure of
      such Lender, any Note held by such Lender, any Commitment of such Lender or
      any
      other interest of such Lender under the Loan Documents. In the event of any
      such
      sale by a Lender of participating interests to a Participant, such Lender’s
      obligations under the Loan Documents shall remain unchanged, such Lender shall
      remain solely responsible to the other parties hereto for the performance of
      such obligations, such Lender shall remain the owner of its Outstanding Credit
      Exposure and the holder of any Note issued to it in evidence thereof for all
      purposes under the Loan Documents, all amounts payable by the Borrowers under
      this Agreement shall be determined as if such Lender had not sold such
      participating interests, and the Borrowers and the Agent shall continue to
      deal
      solely and directly with such Lender in connection with such Lender’s rights and
      obligations under the Loan Documents.

     

    12.2.2
        Voting
      Rights.
      Each
      Lender shall retain the sole right to approve, without the consent of any
      Participant, any amendment, modification or waiver of any provision of the
      Loan
      Documents other than any amendment, modification or waiver with respect to
      any
      Credit Extension or Commitment in which such Participant has an interest which

    12.2.3
        Benefit
      of Certain Provisions.
      The
      Borrowers agree that each Participant shall be deemed to have the right of
      setoff provided in Section 11.1 in respect of its participating interest in
      amounts owing under the Loan Documents to the same extent as if the amount
      of
      its participating interest were owing directly to it as a Lender under the
      Loan
      Documents, provided
      that
      each Lender shall retain the right of setoff provided in Section 11.1 with
      respect to the amount of participating interests sold to each Participant.
      The
      Lenders agree to share with each Participant, and each Participant, by
      exercising the right of setoff provided in Section 11.1, agrees to share with
      each Lender, any amount received pursuant to the exercise of its right of
      setoff, such amounts to be shared in accordance with Section 11.2 as if each
      Participant were a Lender. The Borrowers further agree that each Participant
      shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the
      same
      extent as if it were a Lender and had acquired its interest by assignment
      pursuant to Section 12.3, provided
      that (i)
      a Participant shall not be entitled to receive any greater payment under Section
      3.1, 3.2 or 3.5 than the Lender who sold the participating interest to such
      Participant would have received had it retained such interest for its own
      account, unless the sale of such interest to such Participant is made with
      the
      prior written consent of the Borrowers, and (ii) any Participant not
      incorporated under the laws of the United States of America or any State thereof
      agrees to comply with the provisions of Section 3.5 to the same extent as if
      it
      were a Lender.

     

    12.3.  Assignments.

     

    12.3.1
        Permitted
      Assignments.
      Any
      Lender may at any time assign to one or more banks or other entities
      (“Purchasers”) all or any part of its rights and obligations under the Loan
      Documents. Such assignment shall be evidenced by an agreement substantially
      in
      the form of Exhibit C or in such other form as may be agreed to by the parties
      thereto (each such agreement, an “Assignment Agreement”). Each such assignment
      with respect to a Purchaser which is not a Lender or an Affiliate of a Lender
      or
      an Approved Fund shall either be in an amount equal to the entire applicable
      Commitment and Outstanding Credit Exposure of the assigning Lender or (unless
      each of the Borrowers and the Agent otherwise consents) be in an aggregate
      amount not less than $5,000,000. The amount of the assignment shall be based
      on
      the Commitment or, if the Commitments have been terminated, the Outstanding
      Credit Exposure subject to the assignment, determined as of the date of such
      assignment or as of the “Trade Date,” if the “Trade Date” is specified in the
      Assignment Agreement. Each partial assignment shall be made as an assignment
      of
      a proportionate part of all the assigning Lender’s rights and obligations under
      this Agreement, except that this sentence shall not apply to rights in respect
      of outstanding Competitive Loans.

     

    12.3.2
        Consents.
      The
      consent of the Borrowers shall be required prior to an assignment becoming
      effective unless the Purchaser is a Lender, an Affiliate of a Lender or an
      Approved Fund, provided
      that the
      consent of the 

     

    
      
        
        

      

      
        73

        
          

        

      

      
        
        

      

    

     

    Borrowers
      shall not be required if (i) a Default has occurred and is continuing or (ii)
      such assignment is in connection with the physical settlement of any Lender’s
      obligations to direct or indirect contractual counterparties in swap agreements
      relating to the Loans; provided,
      that
      the assignment without the Borrowers’ consent pursuant to clause (ii) shall not
      increase the Borrowers’ liability under Section 3.5. The consent of the Agent
      and each Issuing Bank shall be required prior to an assignment becoming
      effective. Any consent required under this Section 12.3.2 shall not be
      unreasonably withheld or delayed (except that any Issuing Bank may withhold
      such
      consent in its sole discretion).

     

    12.3.3
        Effect;
      Effective Date.
      Upon
      (i) delivery to the Agent of an Assignment Agreement, together with any consents
      required by Sections 12.3.1 and 12.3.2, and (ii) payment of a $3,500 fee to
      the
      Agent for processing such assignment (unless such fee is waived by the Agent),
      such assignment shall become effective on the effective date specified in such
      assignment. The Assignment Agreement shall contain a representation and warranty
      by the Purchaser to the effect that none of the funds, money, assets or other
      consideration used to make the purchase and assumption of the Commitment and
      Outstanding Credit Exposure under the applicable Assignment Agreement
      constitutes “plan assets” as defined under ERISA and that the rights, benefits
      and interests of the Purchaser in and under the Loan Documents will not be
“plan
      assets” under ERISA. On and after the effective date of such assignment, such
      Purchaser shall for all purposes be a Lender party to this Agreement and any
      other Loan Document executed by or on behalf of the Lenders and shall have
      all
      the rights, benefits and obligations of a Lender under the Loan Documents,
      to
      the same extent as if it were an original party thereto, and the transferor
      Lender shall be released with respect to the Commitment and Outstanding Credit
      Exposure, if any, assigned to such Purchaser without any further consent or
      action by the Borrowers, the Lenders or the Agent. In the case of an assignment
      covering all of the assigning Lender’s rights, benefits and obligations under
      this Agreement, such Lender shall cease to be a Lender hereunder but shall
      continue to be entitled to the benefits of, and subject to, those provisions
      of
      this Agreement and the other Loan Documents which survive payment of the
      Obligations and termination of the Loan Documents. Any assignment or transfer
      by
      a Lender of rights or obligations under this Agreement that does not comply
      with
      this Section 12.3 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
      Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant
      to
      this Section 12.3.3, the transferor Lender, the Agent and the Borrowers shall,
      if the transferor Lender or the Purchaser desires that its Loans be evidenced
      by
      Notes, make appropriate arrangements so that, upon cancellation and surrender
      to
      the Borrowers of the Notes (if any) held by the transferor Lender, new Notes
      or,
      as appropriate, replacement Notes are issued to such transferor Lender, if
      applicable, and new Notes or, as appropriate, replacement Notes, are issued
      to
      such Purchaser, in each case in principal amounts reflecting their

    respective
      Commitments (or, if such Commitments have been terminated, their respective
      Outstanding Credit Exposure), as adjusted pursuant to such
      assignment.

     

    12.3.4
        Register.
      The
      Agent, acting solely for this purpose as an agent of the Borrowers (and the
      Borrowers hereby designate the Agent to act in such capacity), shall maintain
      at
      one of its offices in New York, New York a copy of each Assignment and
      Assumption delivered to it and a register (the “Register”) for the recordation
      of the names and addresses of the Lenders, and the Commitments of, and principal
      amounts of and interest on the Loans owing to, each Lender pursuant to the
      terms
      hereof from time to time and whether such Lender is an original Lender or
      assignee of another Lender pursuant to an assignment under this Section 13.3.
      The entries in the Register shall be conclusive, absent manifest error and
      the
      Borrowers, the 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 Borrowers and any Lender,
      at
      any reasonable time and from time to time upon reasonable prior
      notice.

     

    12.4.  Dissemination
      of Information.
      The
      Borrowers authorize each Lender to disclose to any Participant or Purchaser
      or
      any other Person acquiring an interest in the Loan Documents by operation of
      law
      (each a “Transferee”) and any prospective Transferee any and all information in
      such Lender’s possession concerning the creditworthiness of the Borrowers and
      their Subsidiaries; provided
      that
      each Transferee and prospective Transferee agrees to be bound by Section 9.11
      of
      this Agreement.

     

    12.5.  Tax
      Certifications.
      If any
      interest in any Loan Document is transferred to any Transferee which is not
      incorporated under the laws of the United States or any State thereof, the
      transferor Lender shall cause such Transferee, concurrently with the
      effectiveness of such transfer, to comply with the provisions of Section
      3.5(iv).

    Dear
      Ladies and Gentlemen:

     

    I
      am the
      Senior Vice President, General Counsel and Secretary of Ameren Corporation,
      a
      Missouri corporation (the “Company”),
      and
      its subsidiaries Union Electric Company, a Missouri corporation, Central
      Illinois Public Service Company, an Illinois corporation, Central Illinois
      Light
      Company, an Illinois corporation, Ameren Energy Generating Company, an Illinois
      corporation and Illinois Power Company, an Illinois corporation (the Company
      and
      such subsidiaries each a “Borrower”
      and
      collectively, the “Borrowers”).
      I, or
      lawyers under my direction, have acted as counsel for the Borrowers in
      connection with the Five-Year Revolving Credit Agreement dated as of July 14,
      2005 (the “Credit Agreement”), among the Borrowers, the lending institutions
      identified therein as Lenders and JPMorgan Chase Bank, N.A., as Administrative
      Agent. Terms defined in the Credit Agreement are used herein with the same
      meanings.

     

    In
      rendering the opinion expressed below, I, or lawyers under my direction, have
      examined originals or copies, certified or otherwise identified to my
      satisfaction, of such documents, corporate records, certificates of public
      officials and other instruments and have conducted such other investigations
      of
      fact and law as I have deemed necessary or advisable for purposes of this
      opinion. In rendering the opinion expressed below with respect to matters of
      Illinois law as it applies to Central Illinois Public Service Company, Central
      Illinois Light Company, Ameren Energy Generating Company and Illinois Power
      Company, I, or lawyers under my direction, have relied on the opinion, of even
      date herewith and addressed to you, of Ronald S. Gieseke, Esq., Associate
      General Counsel of Ameren Services Company, an affiliate of the
      Borrowers.

     

    In
      making
      the examinations described above, I have assumed without independent
      investigation the capacity of natural persons (other than the office held by
      each representative of the Borrowers) as reflected adjacent to such individual’s
      signature on the Credit Agreement, the genuineness of all signatures (other
      than
      those of representatives of the Borrowers appearing on the Credit Agreement),
      the authenticity of all documents furnished to me as originals, the conformity
      to originals of all documents furnished to me as certified or photostatic copies
      and the authenticity of the originals of such documents. In addition, I have
      assumed without independent investigation that

     

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    (i) the
      Credit Agreement has been duly authorized, executed and delivered by the Lenders
      and the Agent, and constitutes their valid, lawful and binding obligation and
      agreement, and (ii) there is no separate agreement, undertaking, or course
      of
      dealing modifying, varying or waiving any of the terms of the Credit Agreement.
      As to matters of fact not independently established by me relevant to the
      opinions set forth herein, I have relied without independent investigation
      on
      the representations contained in the Credit Agreement and in certificates of
      public officials and responsible representatives of each Borrower furnished
      to
      me; provided,
      however,
      that I
      advise that in the course of my representation of the Borrowers, I obtained
      no
      information that leads me to believe that any such representation or certificate
      is untrue or misleading in any material respect.

     

    Upon
      the
      basis of and subject to the foregoing, I am of the opinion that:

     

    Each
      of
      the Borrowers and each of their Subsidiaries is a corporation, partnership
      (in
      the case of Subsidiaries only) or limited liability company duly and properly
      incorporated or organized, as the case may be, validly existing and (to the
      extent such concept applies to such entity) in good standing under the laws
      of
      its jurisdiction of incorporation or organization and has all requisite
      authority to conduct its business as presently conducted in each jurisdiction
      in
      which its business is conducted.

     

    Each
      Borrower has the power and authority and legal right to execute and deliver
      the
      Loan Documents and to perform its obligations thereunder. The execution and
      delivery by each Borrower of the Loan Documents and the performance by each
      Borrower of its obligations thereunder have been duly authorized by proper
      proceedings, and the Loan Documents to which such Borrower is a party constitute
      legal, valid and binding obligations of such Borrower enforceable against such
      Borrower in accordance with their terms, except as enforceability may be limited
      by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar
      laws relating to or affecting the enforcement of creditors’ rights generally;
      (ii) general equitable principles (whether considered in a proceeding in equity
      or at law); and (iii) requirements of reasonableness, good faith and fair
      dealing.

     

    Neither
      the execution and delivery by each Borrower of the Loan Documents, nor the
      consummation of the transactions therein contemplated, nor compliance with
      the
      provisions thereof will violate (i) any law, rule, regulation, order, writ,
      judgment, injunction, decree or award binding on such Borrower or any of its
      Subsidiaries, or (ii) such Borrower’s or any Subsidiary’s articles or
      certificate of incorporation, partnership agreement, certificate of partnership,
      articles or certificate of organization, by-laws, or operating agreement or
      other management agreement, as the case may be, or (iii) the provisions
      of
      any indenture, instrument or agreement to which such Borrower or any of its
      Subsidiaries is a party or is subject, or by which it, or its Property, is
      bound, or conflict with, or constitute a default under, or result in, or
      require, the creation or imposition of any Lien in, of or on the Property of
      such Borrower or a Subsidiary pursuant to the terms of, any such indenture,
      instrument or agreement. No order, consent, adjudication, approval, license,
      authorization, or validation of, or filing, recording or registration with,
      or
      exemption by, or other action in respect of any governmental or public body
      or
      authority, or any subdivision thereof, which has not been obtained by each
      

     

     

    
      
        2

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    Borrower
      or any of its Subsidiaries, is required to be obtained by such Borrower or
      any
      of its Subsidiaries in connection with the execution and delivery of the Loan
      Documents, the borrowings and issuances of Letters of Credit under the Credit
      Agreement, the payment and performance by such Borrower of the Obligations
      or
      the legality, validity, binding effect or enforceability of any of the Loan
      Documents.

     

    Except
      for the Disclosed Matters, there is no litigation, arbitration, governmental
      investigation, proceeding or inquiry currently existing, or, to the best of
      my
      knowledge after due inquiry, pending or threatened against or affecting any
      Borrower or any of its Subsidiaries, which, if determined adversely to such
      Borrower or to its Subsidiaries, could reasonably be expected to have a Material
      Adverse Effect with respect to such Borrower or which seeks to prevent, enjoin
      or delay the making of any Loans or would adversely effect the legality,
      validity or enforceability of the Loan Documents or the ability of such Borrower
      to perform the transactions contemplated therein.

     

    Neither
      any Borrower nor any Subsidiary of any Borrower is an “investment company” or a
      company “controlled” by an “investment company,” within the meaning of the
      Investment Company Act of 1940, as amended.

     

    The
      Company is a “holding company”, and each of Union Electric, CIPS, CILCO and IP
      is a “public utility company”, as such terms are defined in the Public Utility
      Holding Company Act of 1935, as amended (together with all rules, regulations
      and orders promulgated or otherwise issued in connection therewith, the “Holding
      Company Act”). Pursuant to the Holding Company Act, the Securities and Exchange
      Commission (“SEC”) has issued its orders authorizing: 

     

    
      	(i)  	
              the
                incurrence by the Company or IP of short-term indebtedness for borrowed
                money in an aggregate principal amount not to exceed at any time
                $1,500,000,000 or $500,000,000, respectively, or (b) the issuance
                and sale
                by the Company of capital stock, preferred stock, certain other specified
                securities and long-term indebtedness for borrowed money in an aggregate
                principal amount not to exceed at any time $2,500,000,000, subject
                to,
                among other things, the condition that all such indebtedness be issued
                on
                or before June 30, 2007 and, in the case of short-term indebtedness,
                mature not later than 364 days thereafter, unless the Holding Company
                Act
                is repealed or revised. 

            

    

     

    
      	(ii)  	
              the
                incurrence by Union Electric, CIPS or CILCO of short-term indebtedness
                for
                borrowed money in an aggregate principal amount not to exceed
                $1,000,000,000, $250,000,000 or $250,000,000, respectively, subject
                to,
                among other things, the condition that all such indebtedness be issued
                on
                or before March 31, 2006 and, mature not later than 364 days
                thereafter, unless the Holding Company Act is repealed or
                revised.

            

    

     

    Genco
      is
      certified by the Federal Energy Regulatory Commission (“FERC”) as an “exempt
      wholesale generator” under the Energy Policy Act of 1992. Genco is not a “public
      utility company” under the Holding Company Act. The FERC, in accordance

     

     

    
      
        3

      

      
        
        

        
          

        

      

      
        
        

      

    

    with
      the
      Federal Power Act, has issued an order authorizing the incurrence by Genco
      of
      short-term indebtedness for borrowed money in an aggregate principal amount
      not
      to exceed $300,000,000, subject to, among other things, the condition that
      all
      such indebtedness be issued on or before June 22, 2006 and, mature not
      later than 364 days thereafter, unless the Federal Power Act is repealed or
      revised.

     

    Such
      orders of the SEC and the FERC are in full force and effect. Loans contemplated
      by the Credit Agreement are short-term indebtedness for borrowed money and,
      in
      the case of the Company only, also long-term indebtedness for borrowed money
      within the meaning of the aforesaid orders of the SEC and the FERC. Unless
      such
      authorization is no longer required by applicable laws and regulations,
      additional authorization from the SEC or the FERC (or any governmental agency
      that succeeds to the authority of the SEC or the FERC, as applicable) will
      be
      necessary in order for (i) the Company or IP, after June 30,
      2007,
      (ii) Union Electric, CIPS or CILCO after March 31, 2006, and
      (iii) Genco, after June 22, 2006, to obtain any Advances under
      this
      Agreement or to incur or issue short-term indebtedness for borrowed money and,
      in the case of the Company, long-term indebtedness for borrowed money,
      including, without limitation, Loans extended under the Credit Agreement. No
      other federal governmental consents, approvals, authorizations, registrations,
      declarations or filings are required in connection with the extensions of credit
      under the Credit Agreement or the performance by each Borrower of its
      obligations under the Credit Agreement.

     

    In
      a
      properly presented case, a Missouri court or a federal court applying Missouri
      choice of law rules should give effect to the choice of law provisions of the
      Credit Agreement and should hold that the Credit Agreement is to be governed
      by
      the laws of the State of New York rather than the laws of the State of Missouri.
      In rendering the foregoing opinion, I note that by its terms the Credit
      Agreement expressly selects New York law as the law governing its
      interpretation and that the Credit Agreement was delivered to the Agent in
      New
      York. The choice of law provisions of the Credit Agreement are not voidable
      under the laws of the State of Missouri. Notwithstanding the foregoing, even
      if
      a Missouri court or a federal court holds that the Credit Agreement is to be
      governed by the laws of the State of Missouri, the Credit Agreement constitutes
      a legal, valid and binding obligation of each Borrower thereto, enforceable
      under Missouri law (including usury provisions) against such Borrower in
      accordance with its terms.

     

    I
      express
      no opinion as to the compliance or noncompliance, or the effect of the
      compliance or noncompliance, of any addressee with any state or federal laws
      or
      regulations applicable to it by reason of its status as or affiliation with
      a
      federally insured depository institution.

     

    I
      am a
      member of the Bar of the State of Missouri and the foregoing opinion is limited
      to the laws of the State of Missouri and the Federal laws of the United States
      of America. I note that the Credit Agreement is governed by the laws of the
      State of New York and, for purposes of the opinion expressed in opinion
      paragraph 2 above, I have assumed that the laws of the State of New York do
      not
      differ from the laws of the State of Missouri in any manner that would render
      such opinion incorrect. This opinion is rendered solely to you in connection
      with the above matter. This opinion may not be

      the
      application of the laws of the State of Missouri or the Federal laws of the
      United States of America contained in his opinion addressed to you and dated
      the
      date hereof, Ronald S. Gieseke) without my prior written consent.
      Notwithstanding anything in this opinion letter to the contrary, you may

      delivered as of the date hereof and I undertake no, and disclaim any, obligation
      to advise you of any change in matters of law or fact set forth herein or upon
      which this opinion is based.

    FORM
      OF OPINION FOR ILLINOIS CORPORATIONS

     

    July
      14,
      2005

    

    

    To
      the
      Lenders and 

    JPMorgan
      Chase Bank, N.A., as

    Administrative
      Agent

    270
      Park
      Avenue

    New
      York,
      NY 10017

     

    Dear
      Ladies and Gentlemen:

     

    I
      am an
      Associate General Counsel of Ameren Services Company, a subsidiary of Ameren
      Corporation and an affiliate of Central Illinois Public Service Company, an
      Illinois corporation, Central Illinois Light Company, an Illinois corporation,
      Ameren Energy Generating Company, an Illinois corporation and Illinois Power
      Company, an Illinois corporation (collectively, the “Illinois
      Borrowers”).
      I, or
      lawyers under my direction, have acted as counsel for the Illinois Borrowers
      in
      connection with the Five-Year Revolving Credit Agreement dated as of July 14,
      2005 (the “Credit Agreement”), among Ameren Corporation, Union Electric Company,
      the Illinois Borrowers, the lending institutions identified therein as Lenders
      and JPMorgan Chase Bank, N.A., as Administrative Agent. Terms defined in the
      Credit Agreement are used herein with the same meanings.

     

    In
      rendering the opinion expressed below, I, or lawyers under my direction, have
      examined originals or copies, certified or otherwise identified to my
      satisfaction, of such documents, corporate records, certificates of public
      officials and other instruments and have conducted such other investigations
      of
      fact and law as I have deemed necessary or advisable for purposes of this
      opinion. In rendering the opinion expressed below with respect to matters
      relating to the applications of the laws of the State of Missouri or the Federal
      laws of the United States of America, I have relied on the opinion, of even
      date
      herewith and addressed to you, of Steven R. Sullivan, Senior Vice President,
      General Counsel and Secretary of Ameren Corporation and its subsidiaries Union
      Electric Company, Central Illinois Public Service Company, Central Illinois
      Light Company, Ameren Energy Generating Company and Illinois Power Company.
      

     

    In
      making
      the examinations described above, I have assumed without independent
      investigation the capacity of natural persons (other than the office held by
      each representative of the Illinois Borrowers) as reflected adjacent to such
      individual’s signature on the Credit Agreement, the genuineness of all
      signatures (other than those of representatives of the Illinois Borrowers
      appearing on the Credit Agreement), the authenticity of all documents furnished
      to me as originals, the conformity to originals of all documents furnished
      to me
      as certified or photostatic copies and the authenticity of the

     

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    originals
      of such documents. In addition, I have assumed without independent investigation
      that (i) the Credit Agreement has been duly authorized, executed and
      delivered by the Lenders and the Agent, and constitutes their valid, lawful
      and
      binding obligation and agreement, and (ii) there is no separate agreement,
      undertaking, or course of dealing modifying, varying or waiving any of the
      terms
      of the Credit Agreement. As to matters of fact not independently established
      by
      me relevant to the opinions set forth herein, I have relied without independent
      investigation on the representations contained in the Credit Agreement and
      in
      certificates of public officials and responsible representatives of each
      Illinois Borrower furnished to me; provided,
      however,
      that I
      advise that in the course of my representation of the Illinois Borrowers, I
      obtained no information that leads me to believe that any such representation
      or
      certificate is untrue or misleading in any material respect.

     

    Upon
      the
      basis of and subject to the foregoing, I am of the opinion that:

     

    Each
      of
      the Illinois Borrowers and each of their Subsidiaries is a corporation,
      partnership (in the case of Subsidiaries only) or limited liability company
      duly
      and properly incorporated or organized, as the case may be, validly existing
      and
      (to the extent such concept applies to such entity) in good standing under
      the
      laws of its jurisdiction of incorporation or organization and has all requisite
      authority to conduct its business as presently conducted in each jurisdiction
      in
      which its business is conducted.

     

    Each
      Illinois Borrower has the power and authority and legal right to execute and
      deliver the Loan Documents and to perform its obligations thereunder. The
      execution and delivery by each Illinois Borrower of the Loan Documents and
      the
      performance by each Illinois Borrower of its obligations thereunder have been
      duly authorized by proper proceedings, and the Loan Documents to which such
      Illinois Borrower is a party constitute legal, valid and binding obligations
      of
      such Illinois Borrower enforceable against such Illinois Borrower in accordance
      with their terms, except as enforceability may be limited by (i) bankruptcy,
      insolvency, fraudulent conveyance, reorganization, or similar laws relating
      to
      or affecting the enforcement of creditors’ rights generally; (ii) general
      equitable principles (whether considered in a proceeding in equity or at law);
      and (iii) requirements of reasonableness, good faith and fair
      dealing.

     

    Neither
      the execution and delivery by each Illinois Borrower of the Loan Documents,
      nor
      the consummation of the transactions therein contemplated, nor compliance with
      the provisions thereof will violate (i) any law, rule, regulation, order, writ,
      judgment, injunction, decree or award binding on such Illinois Borrower or
      any
      of its Subsidiaries, or (ii) such Illinois Borrower’s or any Subsidiary’s
      articles or certificate of incorporation, partnership agreement, certificate
      of
      partnership, articles or certificate of organization, by-laws, or operating
      agreement or other management agreement, as the case may be, or (iii) the
      provisions of any indenture, instrument or agreement to which such Illinois
      Borrower or any of its Subsidiaries is a party or is subject, or by which it,
      or
      its Property, is bound, or conflict with, or constitute a default under, or
      result in, or require, the creation or imposition of any Lien in, of or on
      the
      Property of such Illinois Borrower or a Subsidiary pursuant to the terms of,
      any
      such indenture, instrument or agreement. No order, consent, adjudication,
      approval, license, authorization, or 

     

     

    
      
        2

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    validation
      of, or filing, recording or registration with, or exemption by, or other action
      in respect of any governmental or public body or authority, or any subdivision
      thereof, which has not been obtained by each Illinois Borrower or any of its
      Subsidiaries, is required to be obtained by such Illinois Borrower or any of
      its
      Subsidiaries in connection with the execution and delivery of the Loan
      Documents, the borrowings and issuances of Letters of Credit under the Credit
      Agreement, the payment and performance by such Illinois Borrower of the
      Obligations or the legality, validity, binding effect or enforceability of
      any
      of the Loan Documents.

     

    In
      a
      properly presented case, an Illinois court or a federal court applying Illinois
      choice of law rules should give effect to the choice of law provisions of the
      Credit Agreement and should hold that the Credit Agreement is to be governed
      by
      the laws of the State of New York rather than the laws of the State of Illinois.
      In rendering the foregoing opinion, I note that by its terms the Credit
      Agreement expressly selects New York law as the law governing its
      interpretation and that the Credit Agreement was delivered to the Agent in
      New
      York. The choice of law provisions of the Credit Agreement are not voidable
      under the laws of the State of Illinois. Notwithstanding the foregoing, even
      if
      an Illinois court or a federal court holds that the Credit Agreement is to
      be
      governed by the laws of the State of Illinois, the Credit Agreement constitutes
      a legal, valid and binding obligation of each Borrower thereto, enforceable
      under Illinois law (including usury provisions) against such Borrower in
      accordance with its terms.

     

    I
      express
      no opinion as to the compliance or noncompliance, or the effect of the
      compliance or noncompliance, of any addressee with any state or federal laws
      or
      regulations applicable to it by reason of its status as or affiliation with
      a
      federally insured depository institution.

     

    I
      am a
      member of the Bar of the State of Illinois and the foregoing opinion is limited
      to the laws of the State of Illinois and the Federal laws of the United States
      of America. I note that the Credit Agreement is governed by the laws of the
      State of New York and, for purposes of the opinion expressed in opinion
      paragraph 2 above, I have assumed that the laws of the State of New York do
      not
      differ from the laws of the State of Illinois in any manner that would render
      such opinion incorrect. This opinion is rendered solely to you in connection
      with the above matter. This opinion may not be relied upon by you for any other
      purpose or relied upon by any other Person (other than your successors and
      assigns as Lenders and, as to certain matters involving the application of
      the
      laws of the State of Illinois in his opinion addressed to you and dated the
      date
      hereof, Steven R. Sullivan) without my prior written consent. Notwithstanding
      anything in this opinion letter to the contrary, you may disclose this opinion
      (i) to prospective successors and assigns of the addressees hereof, (ii) to
      regulatory authorities having jurisdiction over any of the addressees hereof
      or
      their successors and assigns, and (iii) pursuant to valid legal process, in
      each
      case without my prior consent. This opinion is delivered as of the date hereof
      and I undertake no, and disclaim any, obligation to advise you of any change
      in
      matters of law or fact set forth herein or upon which this opinion is
      based.

      obligations to general creditors) other
      than
      indebtedness which, by its terms or the terms of the instrument creating or
      evidencing it, provides that such indebtedness is subordinated to all other
      indebtedness of such Borrower. Notwithstanding any other provision of this
      Agreement on this Exhibit G, “Senior Debt” shall include refinancings,
      renewals, amendments, extensions or refundings of the indebtedness described
      in
      clauses (i) through (iii) above. 

     

    “Subordinate
      and junior” as used herein shall mean that in the event of:

     

    (a)
      any
      default in, or violation of, the terms or covenants of any Senior Debt,
      including, without limitation, any default in payment of principal of, or
      premium, if any, or interest on, any Senior Debt whenever due (whether by
      acceleration of maturity or otherwise), and during the continuance thereof,
      or

     

    (b)
      the
institution
      of any
      liquidation, dissolution, bankruptcy, insolvency, reorganization or similar
      proceeding relating to CIPS or Genco, as applicable, its property or its
      creditors as such,

     

    the
      obligee of indebtedness so described shall not be entitled to receive any
      payment of principal of, or premium, if any, or interest on, such indebtedness
      until all amounts owing in respect of Senior Debt (matured and unmatured) shall
      have been paid in full; and from and after the happening of any event described
      in clause (b) of this paragraph, all payments and distributions of any
      kind
      or character (whether in cash, securities or property) which, except for the
      subordination provisions hereof, would have been
      

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    payable
      or distributable to the obligee of such indebtedness (whether directly or by
      reason of this note’s being superior to any other indebtedness), shall be made
      to and for the benefit of the holders of Senior Debt (who shall be entitled
      to
      make all necessary claims therefor) in accordance with the priorities of payment
      thereof until all Senior Debt (matured and unmatured) shall have been paid
      in
      full. No act or failure to act on the part of CIPS or Genco, as applicable,
      and
      no default under or breach of any agreement of such Borrower, whether or not
      herein set forth, shall in any way prevent or limit the holder of any Senior
      Debt from enforcing fully the subordination terms herein provided for,
      irrespective of any knowledge or notice which such holder may at any time have
      or be charged with. In the event that any payment or distribution is made with
      respect to Subordinated Debt in violation of the terms of this Exhibit G
      or
      any outstanding Senior Debt, any holder of Subordinated Debt receiving such
      payment or distribution shall hold it in trust for the benefit of, and shall
      remit it to, the holders of Senior Debt then outstanding in accordance with
      the
      priorities of payment thereof.
