      Commitment;
      and

     

    (b)  each
      Deposit Lender
      agrees to make Deposit Loans, with amounts in its Deposit Sub-Account, to any
      Borrower from time to time during the Deposit Availability Period in an
      aggregate principal amount that will not result in any Lender’s Deposit
      Outstandings exceeding such Lender’s Deposit Commitment.

     

    Within
      the
      foregoing limits and subject to the terms and conditions set forth herein,
      each
      Borrower may borrow, prepay and reborrow Revolving Loans and Deposit Loans.
      

     

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

     

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

     

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

     

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

     

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

     

    (i)  the
      Borrower;

     

    (ii)  the
      Class of the
      requested Borrowing;

     

    (iii)  the
      aggregate
      amount of such Borrowing;

     

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

     

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

     

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

     

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

     

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

     

    Section
      2.04  .
      Letters of
      Credit. 

     

    (a)  General.


     

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

     

    (ii)  Existing
      Letters of Credit.
      On the Effective
      Date, without further action by any party hereto, (x) the Deposit Issuing Bank
      shall be deemed to have granted to each Deposit Lender, and each Deposit Lender
      shall be deemed to have acquired from the Deposit Issuing Bank, a participation
      in each Existing Deposit Letter of Credit equal to such Lender’s Deposit
      Percentage of (A) the aggregate amount available to be drawn under such Existing
      Deposit Letter of Credit and (B) the aggregate amount of any outstanding
      reimbursement obligations in respect thereof; and (y) each Revolving Issuing
      Bank that has issued an Existing Revolving Letter of Credit shall be deemed
      to
      have granted to each Revolving Lender, and each Revolving Lender shall be deemed
      to have acquired from such Issuing Bank, a participation in each such Existing
      Revolving Letter of Credit equal to such Lender’s Revolving Percentage of (A)
      the aggregate amount available to be drawn under such Existing Revolving Letter
      of Credit, as applicable, and (B) the aggregate amount of any outstanding
      reimbursement obligations in respect thereof. With respect to each Existing
      Letter of Credit (i) if the relevant Issuing Bank has heretofore sold a
      participation therein to a Lender, such Issuing Bank and such Lender agree
      that
      such participation shall be automatically canceled on the Effective Date and
      (ii) if the relevant Issuing Bank has heretofore sold a participation therein
      to
      any bank or financial institution that is not a Lender, such Issuing Bank shall
      procure the termination of such participation on or prior to the Effective
      Date.
      On and after the Effective Date, each such Existing Letter of Credit shall
      be a
      Letter of Credit issued hereunder.

     

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

     

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

     

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

     

    (e)  Reimbursement.
      If an Issuing
      Bank shall make any LC Disbursement in respect of a Letter of Credit issued
      by
      it, the applicable obligor Borrower shall reimburse such LC Disbursement by
      paying to the Administrative Agent an amount equal to such LC Disbursement
      not
      later than 12:00 noon, New York City time, on the date that such LC Disbursement
      is made, if such Borrower shall have received notice of such LC Disbursement
      prior to 10:00 a.m., New York City time, on such date, or, if such notice has
      not been received by such Borrower prior to such time on such date, then not
      later than 12:00 noon, New York City time, on (i)
      the Business Day
      that such Borrower receives such notice, if such notice is received prior to
      10:00 a.m., New York City time, on the day of receipt, or (ii)
      the Business Day
      immediately following the day that such Borrower receives such notice, if such
      notice is not received prior to such time on the day of receipt; provided
      that, if such LC
      Disbursement is not less than $5,000,000, the Company, on its own behalf or
      on
      behalf of such Borrower, may request in accordance with Section
      2.03
      that such payment be financed with an ABR Borrowing of the applicable Class
      in
      an equivalent amount and, to the extent so financed, such Borrower’s obligation
      to make such payment shall be discharged and replaced by the resulting ABR
      Borrowing. If the applicable obligor Borrower, or any Guarantor on its behalf,
      fails to make such payment when due, the Administrative Agent shall notify
      each
      Lender of the applicable Class of the applicable LC Disbursement, the payment
      then due from such Borrower in respect thereof and such Lender’s Applicable
      Percentage thereof. Promptly following receipt of such notice, each applicable
      Lender shall pay to the Administrative Agent its Applicable Percentage of the
      payment then due from the applicable Borrower, in the same manner as provided
      in
Section
      2.05
      with respect to Loans made by such Lender (and Section
      2.05
      shall apply, mutatis
      mutandis,
      to the payment
      obligations of the applicable Lenders), and the Administrative Agent shall
      promptly pay to the applicable Issuing Bank the amounts so received by it from
      such Lenders. Promptly following receipt by the Administrative Agent of any
      payment from a Borrower pursuant to this paragraph, the Administrative Agent
      shall distribute such payment to the applicable Issuing Bank or, to the extent
      that Lenders have made payments pursuant to this paragraph to reimburse such
      Issuing Bank, then (i) if such payment was made in respect of a Revolving Letter
      of Credit, to the Revolving Lenders and such Issuing Bank as their interests
      may
      appear and (ii) if such payment was made in respect of a Deposit Letter of
      Credit, as required by Section 2.18(b). Any payment made by a Lender pursuant
      to
      this paragraph to reimburse the applicable Issuing Bank for any LC Disbursement
      (other than the funding of ABR Loans as contemplated above) made by such Issuing
      Bank shall not constitute a Loan and shall not relieve the applicable obligor
      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
      2.04
      shall be absolute, unconditional and irrevocable, and shall be performed
      strictly in accordance with the terms of this Agreement under any and all
      circumstances whatsoever and irrespective of (i)
      any lack of
      validity or enforceability of any Letter of Credit or this Agreement, or any
      term or provision therein, (ii)
      any draft or other
      document presented under a Letter of Credit proving to be forged, fraudulent
      or
      invalid in any respect or any statement therein being untrue or inaccurate
      in
      any respect, (iii)
      payment by the
      applicable Issuing Bank under a Letter of Credit against presentation of a
      draft
      or other document that does not comply with the terms of such Letter of Credit,
      or (iv)
      any other event or
      circumstance whatsoever, whether or not similar to any of the foregoing, that
      might, but for the provisions of this Section
      2.04,
      constitute a legal or equitable discharge of or defense to, or provide a right
      of setoff against, a Borrower’s obligations hereunder. Neither the
      Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related
      Parties, shall have any liability or responsibility by reason of or in
      connection with the issuance or transfer of any Letter of Credit or any payment
      or failure to make any payment thereunder (irrespective of any of the
      circumstances referred to in the preceding sentence), or any error, omission,
      interruption, loss or delay in transmission or delivery of any draft, notice
      or
      other communication under or relating to any Letter of Credit (including any
      document required to make a drawing thereunder), any error in interpretation
      of
      technical terms or any consequence arising from causes beyond the control of
      such Issuing Bank; provided
      that the foregoing
      shall not be construed to excuse such Issuing Bank from liability to a Borrower
      to the extent of any direct damages (as opposed to consequential damages, claims
      in respect of which are hereby waived by the applicable Borrower to the extent
      permitted by applicable law) suffered by a Borrower that are caused by such
      Issuing Bank’s failure to 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 any such Issuing Bank (as
      finally determined by a court of competent jurisdiction), such Issuing Bank
      shall be deemed to have exercised care in each such determination. In
      furtherance of the foregoing and without limiting the generality thereof, 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,
      the
      Issuing Bank that issued such Letter of Credit 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 (unless the
      applicable obligor Borrower shall consent to payment thereon notwithstanding
      such lack of strict compliance). 

     

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

     

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

     

    (i)  Replacement
      of
      an Issuing Bank.
      Any Issuing Bank
      may be replaced at any time by written agreement among the Company, the
      Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank.
      The Administrative Agent shall notify the Lenders of any such replacement of
      an
      Issuing Bank. At the time any such replacement shall become effective, the
      applicable obligor Borrower shall pay all unpaid fees accrued for the account
      of
      the replaced Issuing Bank pursuant to Section
      2.10(b).
      From and after
      the effective date of any such replacement, (i)
      the successor
      Issuing Bank shall have all the rights and obligations of the replaced Issuing
      Bank under this Agreement with respect to Letters of Credit issued by it
      thereafter and (ii)
      references herein
      to the term “Issuing
      Bank”
shall
      be deemed,
      when applicable, to refer to such successor or, when applicable, to any previous
      Issuing Bank, or to such successor and all previous Issuing Banks, as the
      context shall require. After the replacement of an Issuing Bank hereunder,
      the

      Collateralization.
      Notwithstanding
      any provisions of the Security Agreement relating to the Cash Collateralization
      of LC Exposure, if any Event of Default shall occur and be continuing, on the
      Business Day that any Borrower receives notice from the Administrative Agent
      or
      the Majority Lenders demanding the Cash Collateralization of the LC Exposure
      pursuant to this paragraph, such Borrower shall Cash Collateralize the LC
      Exposure; provided

      If
      any Borrower is required to provide an amount of Cash Collateral hereunder
      as a
      result of the occurrence of an Event of Default, such amount (to the extent
      not
      applied as aforesaid) shall be returned to such Borrower within three Business
      Days after all Events of Default have been cured or waived.

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

     

    (b)  Each
      Deposit Lender
      hereby authorizes and directs the Administrative Agent to make its Deposit
      Percentage of each Deposit Borrowing available to the applicable Borrower by
      withdrawing from the Deposit Account (and debiting such Lender’s Deposit
      Sub-Account in the amount of) such Lender’s Deposit Percentage of such Borrowing
      in accordance with Section 2.18(c)(i) and making such amount available to the
      applicable Borrower as provided in paragraph (a) of this Section
      2.05.

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

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

     

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

     

    (d)  Within
      five days
      after the occurrence of a Mandatory Asset Reduction Event, first,
      the Deposit
      Commitments shall be ratably reduced (but not below zero) and, second,
      if the Deposit
      Commitments have been reduced to zero, the Revolving Commitments shall be
      ratably reduced (but not below zero), the total reductions under this subsection
      being an aggregate amount equal to the Mandatory Asset Reduction
      Amount.

      termination or
      reduction of the Commitments of any Class hereunder, whether optional or
      mandatory, shall be permanent. Each reduction of the Commitments of either
      Class
      shall be made ratably among the Lenders in accordance with their respective
      Commitments of such Class.

      principal or interest due and payable or to become due and payable to each
      Lender hereunder on account of each Loan from the relevant Borrower to whom
      such
      Loan was made and (iii)

      existence and amounts of the obligations of each Borrower recorded therein
      absent manifest error; provided
      that the failure
      of any Lender or the Administrative Agent to maintain any such account or any
      error therein shall not in any manner affect the obligation of each Borrower
      to
      repay the Loans made to such Borrower in accordance with the terms of this
      Agreement.

      Lender may

      pursuant to Section 2.07(d)) the aggregate Deposit Outstandings or Revolving
      Outstandings exceed the then aggregate Commitments of the related Class, then,

      Period therefor, accrued interest on such Loan shall be payable on the effective
      date of such conversion.

     

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

     

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

     

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

     

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

     

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

     

    Section
      2.13  .
      Increased
      Costs. 

     

    (a)  If
      any Change in
      Law shall:

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

    (d)  Unless
      the
      Administrative Agent shall have received notice from a Borrower prior to the
      date on which any payment is due to the Administrative Agent for the account
      of
      the Lenders or any Issuing Bank hereunder that such Borrower will not make
      such
      payment, the Administrative Agent may assume that such Borrower has made such
      payment on such date in accordance herewith and may, in reliance upon such
      assumption, distribute to the Lenders or the applicable Issuing Bank, as the
      case may be (or, to the extent provided in Section 2.18(b), deposit in the
      Deposit Account), the amount due. In such event, if such Borrower has not in
      fact made such payment, then each of the Lenders or any applicable Issuing
      Bank,
      as the case may be, severally agrees to repay to the Administrative Agent
      forthwith on demand the amount so distributed to such Lender or such Issuing
      Bank (or, if such amount shall have been deposited in the Deposit Account,
      each
      Deposit Lender authorizes the Administrative Agent to withdraw such amount
      from
      the Deposit Account), with interest thereon, for each day from and including
      the
      date such amount is distributed to it (or deposited in the Deposit Account
      and
      credited to its Deposit Sub-Account) to but excluding the date of payment to
      or
      recovery by the Administrative Agent, at the greater of the Federal Funds
      Effective Rate and a rate determined by the Administrative Agent in accordance
      with banking industry rules on interbank compensation.

     

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

     

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

     

    (b)  If
      (w) any Lender
      requests compensation under Section
      2.13,
      or (x) if any Borrower is required to pay any additional amount to any Lender
      or
      any Governmental Authority for the account of any Lender pursuant to
Section
      2.15,
      or (y) if any Lender defaults in its obligation to fund Loans hereunder or
      (z)
      any Lender (or any Lender of the applicable Class) refuses to grant its approval
      with respect to any matter requiring the approval of all Lenders (or all Lenders
      of a Class) and such matter shall have been approved by Lenders having Credit
      Exposures in excess of 66-2/3%
      of the aggregate
      Credit Exposures (or, with respect to Lenders of a particular Class, Lenders
      of
      such Class having Credit Exposures in excess of 66-2/3%
      of the aggregate
      Credit Exposures of such Class), then the Company may, at its sole expense
      and
      effort, upon notice to such Lender and the Administrative Agent, require such
      Lender to assign and delegate, without recourse (in accordance with and subject
      to the restrictions contained in Section
      10.04),
      all its
      interests, rights and obligations under this Agreement to an assignee that
      shall
      assume such obligations (which assignee may be another Lender, if a Lender
      accepts such assignment); provided
      that (i)
      the Company shall
      have received the prior written consent of the Administrative Agent, which
      consent shall not unreasonably be withheld, (ii)
      such Lender shall
      have received payment of an amount equal to the outstanding principal of its
      Loans, participations in LC Disbursements and its Deposit (if any), accrued
      interest thereon, accrued fees and all other amounts payable to it hereunder,
      from the assignee (to the extent of such outstanding principal, participations
      in LC Disbursements, Deposit and accrued interest and fees) or the Borrowers
      (in
      the case of all other amounts) and (iii)
      in the case of any
      such assignment resulting from a claim for compensation under Section
      2.13
      or payments required to be made pursuant to Section
      2.15,
      such assignment will result in a reduction in such compensation or payments.
      A
      Lender shall not be required to make any such assignment and delegation if,
      prior thereto, as a result of a waiver by such Lender or otherwise, the
      circumstances entitling the Company to require such assignment and delegation
      cease to apply.

     

    Section
      2.18  .
      Deposit
      Account. (a) Establishment
      of
      Deposit Account and Deposit Sub-Accounts.
      On or prior to
      the Effective Date, the Administrative Agent shall establish a deposit account
      in the name of the Administrative Agent at JPMCB with the title “El Paso 2006
      Deposit-Funded Credit Facility Deposit Account” (the “Deposit
      Account”).
      The
      Administrative Agent shall maintain records enabling it to determine at any
      time
      the amount of the interest of each Deposit Lender in the Deposit Account (the
      interest of each such Lender in the Deposit Account, as evidenced by such
      records, being referred to as such Lender’s “Deposit
      Sub-Account”).
      The
      Administrative Agent shall establish such additional Deposit Sub-Accounts for
      assignee Deposit Lenders as shall be required pursuant to Section
      10.04(b).
      No Person (other
      than the Administrative Agent) shall have the right to make any withdrawal
      from
      the Deposit Account or to exercise any other right or power with respect thereto
      except as expressly provided in paragraph (c) below or in Section
      10.04(b).
      Without limiting
      the generality of the foregoing, each party hereto acknowledges and agrees
      that
      the Deposits are and will at all times be property of the Deposit Lenders,
      and
      that no amount on deposit at any time in the Deposit Account shall be the
      property of any of the Credit Parties, constitute “Collateral” under the Loan
      Documents or otherwise be available in any manner to satisfy any Obligations
      of
      any of the Credit Parties under the Loan Documents. Each Deposit Lender agrees
      that its right, title and interest in and to the Deposit Account shall be
      limited to the right to require amounts in its Deposit Sub-Account to be applied
      as provided in paragraph (c) below and that it will have no right to require
      the
      return of its Deposit other than as expressly provided in such paragraph (c)
      (each Deposit Lender hereby acknowledging that (i) its Deposit constitutes
      payment for its participations in Deposit Letters of Credit issued or to be
      issued hereunder, (ii) its Deposit and any investments made therewith shall
      secure its obligations to the Deposit Issuing Bank hereunder (each such Lender
      hereby granting to the Administrative Agent, for the benefit of the Deposit
      Issuing Bank, a security interest in its Deposit and agreeing that the
      Administrative Agent, as holder of the Deposits and any investments made
      therewith, will be acting, inter alia,
      as collateral
      agent for the Deposit Issuing Bank) and (iii) the Deposit Issuing Bank will
      be
      issuing, amending, renewing and extending Letters of Credit in reliance on
      the
      availability of such Lender’s Deposit to discharge such Lender’s obligations in
      accordance with Section
      2.04(e)
      in connection with
      any LC Disbursement thereunder). The funding of the Deposits and the agreements
      with respect thereto set forth in this Agreement constitute arrangements among
      the Administrative Agent, the Deposit Issuing Bank and the Deposit Lenders
      with
      respect to the funding obligations of the Deposit Lenders under this Agreement,
      and the Deposits do not constitute loans or extensions of credit to any Credit
      Party. No Credit Party shall have any responsibility or liability to the Deposit
      Lenders, the Agents or any other Person in respect of the establishment,
      maintenance, administration or misappropriation of the Deposit Account (or
      any
      Deposit Sub-Account) or with respect to the investment of amounts held therein,
      including pursuant to paragraph (d) below, or the duties and responsibilities
      of
      the Administrative Agent with respect to the foregoing contemplated by paragraph
      (e) below. JPMCB hereby waives any right of setoff against the Deposits that
      it
      may have under applicable law or otherwise with respect to amounts owed to
      it by
      Deposit Lenders (it being agreed that such waiver shall not reduce the rights
      of
      JPMCB, in its capacity as the Deposit Issuing Bank or otherwise, to apply or
      require the application of the Deposits in accordance with the provisions of
      this Agreement).

     

    (b)  Deposits
      in
      Deposit Account.
      The following
      amounts will be deposited in the Deposit Account at the following
      times:

     

    (i)  On
      the Effective
      Date, each Deposit Lender shall deposit in the Deposit Account an amount in
      dollars equal to such Lender’s Deposit Commitment. Thereafter, the Deposits
      shall be available, on the terms and subject to the conditions set forth herein,
      (A) to fund Deposit Loans by such Lender pursuant to Section 2.01(b) and (B)
      for
      application pursuant to Section
      2.04(e)
      to reimburse such
      Lender’s Deposit Percentage of LC Disbursements in respect of Deposit Letters of
      Credit that are not reimbursed by the applicable Borrower. The obligations
      of
      the Deposit Lenders to make the Deposits required by this clause (i) are
      several, and no Deposit Lender shall be responsible for any other Lender’s
      failure to make its Deposit as so required.

     

    (ii)  On
      any date prior
      to the Deposit Maturity Date on which the Administrative Agent receives any
      payment for the account of any Deposit Lender with respect to the principal
      amount of any of its Deposit Loans, subject to clause (iv) below, the
      Administrative Agent shall deposit such amount in the Deposit Account and credit
      such amount to the Deposit Sub-Account of such Lender.

     

    (iii)  On
      any date prior
      to the Deposit Maturity Date on which the Administrative Agent or the Deposit
      Issuing Bank receives any reimbursement payment from any Borrower in respect
      of
      an LC Disbursement with respect to which amounts were withdrawn from the Deposit
      Account to reimburse the Deposit Issuing Bank, subject to clause (iv) below,
      the
      Administrative Agent shall deposit such reimbursement payment in the Deposit
      Account, and credit to the Deposit Sub-Account of each of the Deposit Lenders,
      such Deposit Lender’s Deposit Percentage of such reimbursement payment, in
      accordance with Section
      2.04(e).

     

    (iv)  If
      at any time when
      any amount would otherwise be required to be deposited in the Deposit Account
      under clause (ii) or (iii) above the sum of such amount and the aggregate amount
      of the Deposits at such time would exceed (x) the aggregate amount of the
      Deposit Commitments minus (y) the aggregate principal amount of all outstanding
      Deposit Loans, then such excess shall not be deposited in the Deposit Account
      and the Administrative Agent shall instead pay to each Deposit Lender its
      Deposit Percentage of such excess.

     

    (v)  Concurrently
      with
      the effectiveness of any assignment by any Lender of all or any portion of
      its
      Deposit Commitment, the Administrative Agent shall transfer into the Deposit
      Sub-Account of the assignee the corresponding portion of the amount on deposit
      in the assignor’s Deposit Sub-Account in accordance with Section
      10.04(b).

     

    (c)  Withdrawals
      From
      and Closing of Deposit Account. Amounts
      on deposit
      in the Deposit Account shall be withdrawn and distributed (or transferred,
      in
      the case of clause (v) below) by the Administrative Agent as
      follows:

     

    (i)  On
      each date on
      which a Deposit Borrowing is to be made, the Administrative Agent shall,
      pursuant to Section
      2.05,
      and subject to the satisfaction of the conditions applicable thereto set forth
      in Article
      3,
      withdraw from the Deposit Account the principal amount of such Borrowing (and
      debit the Deposit Sub-Account of each Deposit Lender in the amount of such
      Lender’s Deposit Percentage of such Borrowing) and make such amount available to
      the applicable Borrower in accordance with Section 2.05(a).

     

    (ii)  On
      each date on
      which the Deposit Issuing Bank is to be reimbursed by the Deposit Lenders
      pursuant to Section 2.04(e) for any LC Disbursement, the Administrative Agent
      shall withdraw from the Deposit Account the amount of such unreimbursed LC
      Disbursement (and debit the Deposit Sub-Account of each Deposit Lender in the
      amount of such Lender’s Deposit Percentage of such unreimbursed LC Disbursement)
      and make such amount available to the Deposit Issuing Bank in accordance with
      Section 2.04(e).

     

    (iii)  Concurrently
      with
      each voluntary reduction of the Deposit Commitments pursuant to and in
      accordance with Section
      2.07(b),
      the
      Administrative Agent shall withdraw from the Deposit Account and pay to each
      Deposit Lender such Lender’s Deposit Percentage of any amount by which the
      Deposits would exceed (x) the aggregate amount of the Deposit Commitments,
      after
      giving effect to such reduction of the Deposit Commitments, minus (y) the
      aggregate principal amount of the outstanding Deposit Loans.

     

    (iv)  Concurrently
      with
      any termination of the Deposit Commitments pursuant to and in accordance with
      Section
      2.07(a)
      or Article
      7,
      the
      Administrative Agent shall withdraw from the Deposit Account and pay to each
      Deposit Lender such Lender’s Deposit Percentage of the excess at such time of
      the aggregate amount of the Deposits over the Deposit LC Exposure.

     

    (v)  Concurrently
      with
      the effectiveness of any assignment by any Deposit Lender of all or any portion
      of its Deposit Commitment, the corresponding portion of the assignor’s Deposit
      Sub-Account shall be transferred from the assignor’s Deposit Sub-Account to the
      assignee’s Deposit Sub-Account in accordance with Section
      10.04(b)
      and, if required
      by Section
      10.04(b),
      the
      Administrative Agent shall close such assignor’s Deposit
      Sub-Account.

     

    (vi)  Upon
      the reduction
      of each of the Deposit Commitments and the Deposit LC Exposure to zero, the
      Administrative Agent shall withdraw from the Deposit Account and pay to each
      Deposit Lender such Lender’s Deposit Percentage of the remaining amount, and
      shall close the Deposit Account.

     

    Each
      Deposit Lender
      irrevocably and unconditionally agrees that its Deposit may be applied or
      withdrawn from time to time as set forth in this paragraph (c).

     

    (d)  Investment
      of
      Amounts in Deposit Account.
      The
      Administrative Agent shall invest, or cause to be invested, the Deposit of
      each
      Deposit Lender so as to earn for the account of such Lender a return thereon
      (the “Deposit
      Return”)
      for each day at
      a rate per annum equal to (i) the one month LIBOR rate as determined by the
      Administrative Agent on such day (or if such day was not a Business Day, the
      first Business Day immediately preceding such day) based on rates for deposits
      in dollars (as set forth by Bloomberg L.P.-page BTMM or any other comparable
      publicly available service as may be selected by the Administrative Agent)
      (the
“Benchmark
      LIBO Rate”)
      minus (ii) 0.10%
      per annum (based on a 365/366 day year). The Benchmark LIBO Rate will be reset
      on each Business Day. The Deposit Return accrued through and including the
      last
      day of March, June, September and December of each year shall be payable by
      the
      Administrative Agent to each Deposit Lender on the third Business Day following
      such last day, commencing on the first such date to occur after the Effective
      Date, and on the date on which each of the Deposit Commitments and the Deposit
      LC Exposure shall have been reduced to zero, and the Administrative Agent agrees
      to pay to each Deposit Lender the amounts due to it under this sentence. No
      Credit Party shall have any obligation under or in respect of the provisions
      of
      this paragraph (d).

     

    (e)  Sub-Agents.
      As provided in
Article
      9,
      the
      Administrative Agent may perform any and all of its duties and exercise its
      rights and powers contemplated by this Section
      2.18
      by or through one or more sub-agents appointed by it (which may include any
      of
      its Affiliates). The parties hereto acknowledge that on or prior to the
      Effective Date the Administrative Agent has engaged JPMorgan Chase Institutional
      Trust Services to act as its sub-agent in connection with the Deposit Account,
      and that in such capacity JPMorgan Chase Institutional Trust Services shall
      be
      entitled to the benefit of all the provisions of this Agreement contemplated
      by
Article
      9,
      including the provisions of Section
      10.03.

     

    (f)  Sufficiency
      of
      Deposits to Provide for Deposit LC Exposure.
      Notwithstanding
      any other provision of this Agreement, no Deposit Loan shall be made, and no
      Deposit Letter of Credit shall be issued or the stated amount thereof increased,
      if after giving effect thereto the aggregate amount of the Deposits would be
      less than the Deposit LC Exposure. The Administrative Agent agrees to provide,
      at the request of the Deposit Issuing Bank, information to such Issuing Bank
      as
      to the aggregate amount of the Deposits.

     

    (g)  Satisfaction
      of
      Lender Funding Obligations.
      Each Borrower and
      the Deposit Issuing Bank acknowledges and agrees that, notwithstanding any
      other
      provision contained herein, the deposit by each Deposit Lender in the Deposit
      Account on the Effective Date of funds equal to its Deposit Commitment will
      fully discharge the obligation of such Lender to fund Deposit Loans by such
      Lender pursuant to Section
      2.02(a)
      and to reimburse
      such Lender’s Deposit Percentage of LC Disbursements in respect of Deposit
      Letters of Credit that are not reimbursed by the applicable Borrower pursuant
      to
Section
      2.04(d)
      or (e),
      and that no other
      or further payments shall be required to be made by any Deposit Lender in
      respect of any such funding or reimbursement obligations.

      and such notice shall be conclusive and binding. Notwithstanding the foregoing,
      the obligations of the Lenders to make Loans and of the Issuing Banks to issue
      Letters of Credit hereunder shall not become effective unless each of the
      foregoing conditions is satisfied (or waived in accordance with Section
      10.02)
      at or prior to 3:00 p.m., New York City time, on August 31, 2006 (and, in the

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

     

    (a)  The
      representations
      and warranties of each Borrower and each other Credit Party set forth in this

      applicable, unless stated to be made on or as of, or to relate to, a specific
      date or period other than the date of such Borrowing or issuance (or amendment
      or increase in the stated amount).

     

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

     

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

     

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

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

     

    Section
      4.07  .
      Litigation.
There
      is no action,
      suit or proceeding pending, or to the knowledge of any Borrower threatened,
      against or involving any Credit Related Party in any court, or before any
      arbitrator of any kind, or before or by any Governmental Authority, existing
      as
      of the Effective Date (x) that in the reasonable judgment of the Company (taking
      into account the availability of appeals) could reasonably be expected to have
      a
      Material Adverse Effect, except for the proceedings described in the Company’s
      annual report on Form 10-K for the year ended December 31, 2005 or its quarterly
      report on Form 10-Q for the fiscal quarter ended March 31, 2006 (the

      Proceedings”)
      or (y) which
      purports to affect the legality, validity, binding effect or enforceability
      of
      the Loan Documents. Since the date of filing of the 1st
      Quarter 2006 10-Q,
      there has been no adverse change in the status of the Disclosed Proceedings
      that, taking into account the availability of any appeals, could reasonably
      be
      expected to increase materially the likelihood of a Material Adverse Effect
      resulting therefrom.

     

    Section

      Taxes.

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

     

    Section

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

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

     

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

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

     

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

     

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

     

    Section
      4.11  .

      above as may be limited by any applicable bankruptcy, insolvency,
      reorganization, moratorium or similar laws affecting creditors’ rights
      generally. All financing statements have been filed that are necessary to
      perfect any security interest created pursuant to any Security Document that
      can

      necessary to provide control to the Collateral Agent, with respect to any
      Collateral for which control can be established in favor of the Collateral
      Agent
      have been taken, including delivery of such Collateral to the Collateral Agent
      to the extent such Collateral is certificated or for which possession can
      provide perfection with respect thereto.

      of
      the proceeds of each Loan made (or deemed made) and each Letter of Credit issued
      (or deemed issued) on the Effective Date, (a) the fair value of the assets
      of
      each Credit Party, at a fair valuation, will exceed its debts and liabilities,
      subordinated, contingent or otherwise; (b) the present fair saleable value
      of
      the property of each Credit Party will exceed the amount that will be required
      to pay the probable liability of its debts and other liabilities, subordinated,
      contingent or otherwise, as such debts and other liabilities become absolute
      and
      matured; (c) each Credit Party will be able to pay its debts and liabilities,
      subordinated, contingent or otherwise, as such debts and liabilities become
      absolute and matured; and (d) no Credit Party will have unreasonably small

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

     

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

     

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

      Company
      Guarantee. 

     

    (a)  The
      Company hereby
      unconditionally and irrevocably guarantees to the Collateral Agent, for the
      ratable benefit of the Lenders and each of their respective permitted
      successors, endorsees, transferees and assigns, the prompt and complete payment
      by the Pipeline Company Borrowers when due (whether at the stated maturity,
      by
      acceleration or otherwise) of the Obligations. This is a guarantee of payment
      and not collection and the liability of the Company is primary and not
      secondary.

     

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

     

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

     

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

     

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

     

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

     

    Section
      8.05  .
      Reinstatement. The
      guarantee
      contained in this Article
      8
      shall continue to be effective, or be reinstated, as the case may be, if at
      any
      time payment, or any part thereof, of any of the Obligations is rescinded or
      must otherwise be restored or returned by any Agent or any Lender upon the
      insolvency, bankruptcy, dissolution, liquidation or reorganization of the
      Company, any Pipeline Company Borrower or any Subsidiary Guarantor, or upon
      or
      as a result of the appointment of a receiver, intervenor or conservator of,
      or
      trustee or similar officer for, the Company, any Pipeline Company Borrower
      or
      any Subsidiary Guarantor or any substantial part of its or their respective

    ARTICLE
      9

    The
      Agents

     

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

     

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

     

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

     

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

     

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

     

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

     

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

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

     

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

     

    (i)  (A)
      increase the
      Commitment of any Lender, without the written consent of such Lender or (B)
      increase the LC Commitment of any Issuing Bank, without the written consent
      of
      such Issuing Bank;

     

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

     

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

     

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

     

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

     

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

     

    (vii)  release
      the Company
      from its guarantee obligations under Article
      8,

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

     

    (ix)  change
      any of the
      percentages contained in the definition of “Mandatory Asset Reduction Amount”,
      without the written consent of each Lender;

     

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

     

    (xi)  change
      any
      provision of any Loan Document in a manner that by its terms adversely affects
      the rights in respect of payments due to Lenders holding Credit Exposures of
      any
      Class differently than those holding Credit Exposures of any other Class,
      without the written consent of Majority Class Lenders of each adversely affected
      Class;

     

    (xii)  waive
      any condition
      set forth in Section
      3.02
      (including by amending or waiving any provision of Article 4,
5,
6
      or 7
      if the effect of
      such amendment or waiver would be to waive any such condition) for purposes
      of
      any Borrowing of Loans or any issuance (or amendment or increase in the stated
      amount) of a Letter of Credit of any Class, without the written consent of
      the
      Majority Class Lenders; or

     

    (xiii)  alter
      the required
      application of any repayments or prepayments as among the Credit Exposures
      of
      different Classes, without the written consent of the Majority Class Lenders
      of
      each adversely affected Class;

     

    (xiv)  provided
      further that
      (x) no such
      agreement shall amend, modify or otherwise affect the rights or duties of any
      Agent or any Issuing Bank hereunder or under any other Loan Document without
      the
      prior written consent of such Agent or such Issuing Bank, as the case may be,
      and (y) any waiver, amendment or modification of this Agreement that by its
      terms affects the rights or duties under this Agreement of one Class of Lenders
      (but not of any other Class of Lenders) may be effected by an agreement or
      agreements in writing entered into by the Company and the requisite percentage
      in interest of the affected Class of Lenders that would be required to consent
      thereto under this Section if such Class of Lenders were the only Class of
      Lenders hereunder at the time.
      Any such waiver
      and any such amendment or modification shall apply equally to each of the
      Lenders and shall be binding upon the Borrowers, the Lenders, the Issuing Banks
      and the Agents. In the case of any waiver, the Borrower, the Lenders, the
      Issuing Banks and the Agents shall be restored to their former position and
      rights hereunder and under the other Loan Documents, and any Default or Event
      of
      Default waived shall be deemed waived ab
      initio
      and not continuing
      unless such waiver expressly provides otherwise; but no such waiver shall extend
      to any subsequent or other Default or Event of Default; and provided
      further that, in
      addition to Dispositions of Collateral permitted by Section
      6.04(a),
      the Majority
      Lenders may consent to additional Dispositions of Collateral so long as each
      such Disposition is for fair market value on an arms-length basis in a cash
      transaction and 100% of the Net Cash Proceeds thereof shall be deposited into
      the Collateral Account pursuant to the terms and provisions of the Security
      Agreement.

     

    In
      addition, notwithstanding the foregoing, this Agreement may be amended with
      the
      written consent of the Administrative Agent, the Borrowers and the Lenders
      providing the relevant Replacement Revolving Facility (as defined below) to
      permit the refinancing of all Revolving Exposures with a replacement hereunder
      (“Replacement
      Revolving Facility”);
provided
      that (a) the
      aggregate amount of such Replacement Revolving Facility shall not exceed the
      aggregate amount of the replaced Revolving Exposures, (b) the maturity date
      of
      such Replacement Revolving Facility shall not be earlier than the Revolving
      Maturity Date at the time of such replacement and (c) all other terms applicable
      to such Replacement Revolving Facility shall be substantially the same as those
      applicable to the Revolving Exposures hereunder. The Administrative Agent shall
      not unreasonably withhold its consent to the Replacement Revolving
      Facility.

      out-of-pocket expenses incurred by any Issuing Bank in connection with the
      issuance, amendment, renewal or extension of any Letter of Credit by it or

      Credit) and (iii)

      in
      connection with the Loans made or Letters of Credit issued hereunder, including
      all such out-of-pocket expenses incurred during any workout, restructuring
      or

      Borrowers shall indemnify, without duplication, each Agent, each Issuing Bank
      and each Lender, and each Related Party of any of the foregoing Persons (each
      such Person being called an “Indemnitee”)

      or the consummation of the Transactions or any other transactions contemplated
      hereby, (ii)

      of Credit or the use of the proceeds therefrom (including any refusal by the
      applicable Issuing Bank to honor a demand for payment under a Letter of Credit
      issued by it in accordance with applicable law if the documents presented in
      connection with such demand do not strictly comply with the terms of such Letter
      of Credit), (iii)
      any actual or
      alleged presence or release of Hazardous Materials on or from any property

      related expenses are determined by a court of competent jurisdiction by final
      and nonappealable judgment to have resulted from or to have been attributable
      to
      the gross negligence or willful misconduct of such Indemnitee or its employees
      or agents.

      indemnification provisions of this Section
      10.03(b)
      are not intended
      to constitute a guaranty of payment of any principal, interest, facility or
      commitment fees, rental or other lease payments, or analogous amounts, under
      the
      Loans or any other Secured Obligations; provided
      that nothing in
      this Section

      shall limit the
      liability of any Borrower for the payment of the Loans or any Secured
      Obligations, which liability arises under any other Loan Document, including

      Class to the Lenders of such Class) severally agrees to pay to such Agent or
      such Issuing Bank, as the case may be, such Lender’s pro rata share (determined
      as of the time that the applicable unreimbursed expense or indemnity payment
      is
      sought based on the Commitments at such time, or if the Commitments have
      terminated or expired, based on the Credit Exposures (or if the Commitments
      of a
      Class have terminated or expired, the Revolving Exposures or Deposit Exposures,
      as the case may be) at such time) of such unpaid amount; provided
      that the
      unreimbursed expense or indemnified loss, claim, damage, liability or related
      expense, as the case may be, was incurred by or asserted against such Agent
      or
      such Issuing Bank in its capacity as such.

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

      to
      each such assignment) or (ii) if each of the Company (unless an Event of Default
      has occurred and is continuing) and the Administrative Agent otherwise consent,

      in
      effect, the outstanding principal balance of the Loans) of the assigning Lender
      subject to each such assignment (determined as of the date the Assignment and
      Assumption with respect to such assignment is delivered to the Administrative
      Agent) shall be $5,000,000 or any increment of $1,000,000 in excess thereof;
      provided
      that
      related
      Approved Funds shall be aggregated for purposes of such minimum assigned
      amount;

      (iii) if after giving effect to such assignment the Deposit Commitment of the
      assignor Lender shall be zero, the Administrative Agent shall close the Deposit
      Sub-Account of such assignor Lender; and

      by
      such Lender or an Affiliate of such Lender, the assigning Lender shall retain
      the sole right to approve any amendment, modification or waiver of any provision

      that the
      Assignment and Assumption between such Lender and such CLO may provide that
      such
      Lender will not, without the consent of such CLO, agree to any amendment,
      modification or waiver described in the first proviso to Section
      10.02(b)
      that affects such
      CLO.

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

    (b)  Each
      Borrower
      hereby irrevocably and unconditionally submits, for itself and its property,
      to

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

     

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

     

    (d)  Each
      party to this
      Agreement irrevocably consents to service of process in any action or proceeding
      referred to in Section
      10.09
      by the mailing thereof by certified mail, return receipt requested, addressed
      as

      right of any party to this Agreement to serve process in any other manner
      permitted by law.

      Confidentiality. Each
      of the
      Administrative Agent, the Collateral Agent, each Issuing Bank and the Lenders
      agrees to maintain the confidentiality of the Information (as defined below),
      except that Information may be disclosed (a)
      to its and its
      Affiliates’ directors, officers, employees and agents, including accountants,
      legal counsel and other advisors involved in the financing provided for herein
      (it being understood that the Persons to whom such disclosure is made will
      be
      informed of the confidential nature of such Information and instructed to keep
      such Information confidential), (b)
      to the extent
      requested by any regulatory authority, (c)

      this Section, to (i)
      any assignee of or
      Participant in, or any prospective assignee of or Participant in, any of its
      rights or obligations under this Agreement, (ii)
      any pledgee
      referred to in Section
      10.04(e)
      or (iii)
      any actual or
      prospective counterparty (or its advisors) to any swap or derivative transaction
      relating to any Borrower and its obligations, (g)
      with the consent
      of a Borrower or (h)
      to the extent such
      Information (i)
      becomes publicly
      available other than as a result of a breach of this Section or (ii)
      becomes available
      to the Administrative Agent, the Collateral Agent, any Issuing Bank or any
      Lender on a nonconfidential basis from a source other than a Borrower or any
      of
      its Subsidiaries, the Administrative Agent, the Collateral Agent, any Issuing
      Bank or any other Lender. For the purposes of this Section, “Information”
means
      all
      information received from a Borrower or any of its Subsidiaries relating to
      any
      Borrower or any of its Subsidiaries or its businesses, other than any such
      information that is available to the Administrative Agent, the Collateral Agent,
      any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure
      by
      such Borrower; provided
      that, in the case
      of information received from a Borrower after the date hereof, such information
      is clearly identified at the time of delivery as confidential. Any Person
      required to maintain the confidentiality of Information as provided in this
      Section shall be considered to have complied with its obligation to do so if
      such Person has exercised the same degree of care to maintain the
      confidentiality of such Information as such Person would accord to its own
      confidential information; and nothing in the foregoing authorization shall
      apply
      to any disclosure that would constitute a violation of applicable federal and
      state securities laws.

     

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


     

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

     

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

    For
      purposes of
      this Schedule, the following terms have the following meanings, subject to
      the
      concluding paragraph of this Schedule:

     

    “Level
      I
      Pricing”
applies
      on any
      day on which the Reference Rating is BB or higher by S&P and
      Ba2 or higher by
      Moody’s.

     

    “Level
      II
      Pricing”
applies
      on any
      day on which (i) the Reference Rating is BB- or higher by S&P and
      Ba3 or higher by
      Moody’s and (ii) Level I Pricing does not apply.

     

    “Level
      III
      Pricing”
applies
      on any
      day on which (i) the Reference Rating is B+ or higher by S&P and
      B1 or higher by
      Moody’s and (ii) neither Level I Pricing nor Level II Pricing
      applies.

     

    “Level
      IV
      Pricing”
applies
      on any
      day if no other Pricing Level applies on such day.

     

    “Moody’s”
means
      Moody’s
      Investors Service, Inc.

     

    “Pricing
      Level”
refers
      to the
      determination of which of Level I, Level II, Level III or Level IV Pricing
      applies on any day.

     

    The
“Reference
      Rating”
is
      the credit
      rating assigned to the Revolving Loans by the relevant rating agency;
provided
      that until such
      time as Moody’s assigns an initial rating to the Revolving Loans, the Moody’s
      rating of the Existing Facility shall be deemed its Reference Rating. The rating
      in effect for any day is that in effect at the close of business on such
      day.

     

    “S&P”
means
      Standard
& Poor’s Ratings Services, a division of The McGraw-Hill
      Companies.

     

    For
      avoidance of
      doubt, in the case of split ratings from S&P and Moody’s, the rating to be
      used to determine the applicable Pricing Level is the lower of the two. For
      purposes of the foregoing, if either Moody’s or S&P shall not have in effect
      a rating for the Revolving Loans, then such rating agency shall be deemed to
      have established a rating in Level IV. If the rating system of Moody’s or
      S&P shall change, or if either such rating agency shall cease to be in the
      business of rating debt obligations of the same type as the Revolving Loans, the
      Borrowers and the Lenders shall negotiate in good faith to amend this Schedule
      to reflect such changed rating system or the unavailability of ratings from
      such
      rating agency and, pending the effectiveness of any such amendment, the
      Applicable Rate shall be determined by reference to Level IV.
