make or hold such Loan; provided that any exercise of such option shall not affect
the obligation of a Borrower to repay such Loan in accordance with the terms of
this Agreement.

     

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

     

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

     

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

    (i) the
Borrower;

     

    (ii) the aggregate
amount of such Borrowing;

     

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

     

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

     

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

     

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

     

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

     

    Section
2.04.  Letters
of Credit.

     

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

     

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

            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

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

     

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

            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

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

     

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

    (f) Obligations
Absolute.  Each Borrower’s obligation to reimburse LC
Disbursements as provided in paragraph 
(e) of this 
Section 2.04 shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and
all circumstances whatsoever and irrespective of (i) any lack of validity or
enforceability of any Letter of Credit or this Agreement, or any term or
provision therein, (ii) any draft or other document presented under a Letter of
Credit proving to be forged, fraudulent or invalid in any respect or any
statement therein being untrue or inaccurate in any respect, (iii) payment by
the applicable Issuing Bank under a Letter of Credit against presentation of a
draft or other document that does not comply with the terms of such Letter of
Credit, or (iv) any other event or circumstance whatsoever, whether or not
similar to any of the foregoing, that might, but for the provisions of this

Section 2.04, constitute a legal or equitable discharge of or defense to, or
provide a right of setoff against, a Borrower’s obligations
hereunder.  Neither the Administrative Agent, the Lenders nor any
Issuing Bank, nor any of their Related Parties, shall have any liability or
responsibility by reason of or in connection with the issuance or transfer of
any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), or any error, omission, interruption, loss or delay in
transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a
drawing thereunder), any error in interpretation of technical terms or any
consequence arising from causes beyond the control of  such Issuing
Bank; provided that the
foregoing shall not be construed to excuse such Issuing Bank from liability to a
Borrower to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by the applicable Borrower
to the extent permitted by applicable law) suffered by a Borrower that are
caused by such Issuing Bank’s failure to comply with the requirements of the ISP
or the Uniform Customs, as applicable, when determining whether drafts and other
documents presented under a Letter of Credit comply with the terms
thereof.  In furtherance of the foregoing, the parties agree that,
with respect to documents presented which appear on their face to be in
compliance with the terms of a Letter of Credit, the Issuing Bank that issued
such Letter of Credit may, to the extent it is permitted to do so under the ISP
or Uniform Customs, as applicable, and otherwise in its sole discretion, either
accept and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or
refuse to accept and make payment upon such documents if such documents are not
in strict compliance with the terms of such Letter of Credit (unless the
applicable obligor Borrower shall consent to payment thereon notwithstanding
such lack of strict compliance).

     

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

Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

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

     

    (i) Replacement of an Issuing
Bank.  Any Issuing Bank may be replaced at any time by written
agreement among the Company, the Administrative Agent, the replaced Issuing Bank
and the successor Issuing Bank.  The Administrative Agent shall notify
the Lenders of any such replacement of an Issuing Bank.  At the time
any such
replacement shall become effective, the applicable obligor Borrower shall pay
all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to

Section 2.10(b).  From
and after the effective date of any such replacement, (i) the successor Issuing
Bank shall have all the rights and obligations of the replaced Issuing Bank
under this Agreement with respect to Letters of Credit issued by it thereafter
and (ii) references herein to the term “Issuing Bank” shall be deemed,
when applicable, to refer to such successor or, when applicable, to any previous
Issuing Bank, or to such successor and all previous Issuing Banks, as the
context shall require.  After the replacement of an Issuing Bank
hereunder, the replaced Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of an Issuing Bank under this
Agreement with respect to Letters of Credit issued by it prior to such
replacement, but shall not be required to issue additional Letters of
Credit.

     

    (j) Cash
Collateralization.  Notwithstanding any provisions of the
Security Agreement relating to the Cash Collateralization of LC Exposure, if any
Event of Default shall occur and be continuing, on the Business Day that any
Borrower receives notice from the Administrative Agent or the Majority Lenders
demanding the Cash Collateralization of the LC Exposure pursuant to this paragraph, such
Borrower shall Cash Collateralize the LC Exposure; provided that the obligation to deposit such cash collateral
shall become effective immediately, and such deposit shall become immediately
due and payable, without demand or other notice of any kind, upon the occurrence
of any Event of Default with respect to such Borrower described in paragraph

(f) of 
Article 7.  If
any Borrower is required to provide an amount of Cash Collateral hereunder as a
result of the occurrence of an Event of Default, such amount (to the extent not
applied as aforesaid) shall be returned to such Borrower within three Business
Days after all Events of Default have been cured or waived.

     

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

     

    
      
        
        

      

      
        
          28

          
            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

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

     

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

     

    (b) To make an election
pursuant to this

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

     

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

     

    
      
        
        

      

      
        
          29

          
            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

    (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 details thereof and of such Lender’s portion of each
resulting Borrowing.

     

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

     

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

     

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

     

    (c) The Company shall
notify the Administrative Agent of any election to terminate or reduce the Commitments
under paragraph 
(b) of this 
Section 2.07, or any required reduction of the Commitments under paragraph

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

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

     

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

     

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

     

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

     

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

     

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

     

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

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

     

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

     

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

     

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

     

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

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

     

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

     

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

     

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

     

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

     

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

     

    (d) Accrued interest on each
Loan shall be payable in arrears on each Interest Payment Date for such Loan and
upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph

(c) of this 
Section 2.11 shall be payable
on demand, (ii) in the event of any repayment or prepayment of any Loan,
accrued interest on the principal amount repaid or prepaid shall be payable on
the date of such repayment or prepayment and (iii) in the event of any
conversion of any Eurodollar Loan prior to the end of the current Interest
Period therefor, accrued interest on such Loan shall be payable on the effective
date of such conversion.

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

     

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

     

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

     

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

     

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

     

    Section
2.13.  Increased
Costs.

     

    (a) If any Change in
Law shall:

     

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

     

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

     

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

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

     

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

     

    (d) Failure or delay on the
part of any Lender or any Issuing Bank to demand compensation pursuant to this

Section 2.13 shall not constitute a waiver of such Lender’s or such Issuing
Bank’s right to demand such compensation; provided that a Borrower shall not be required to compensate
a Lender or an Issuing Bank pursuant to this Section for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender or
such Issuing Bank, as the case may be, notifies the Company of the Change in Law
giving rise to such increased costs or reductions and of such Lender’s or such
Issuing Bank’s intention to claim compensation therefor in accordance
with this Section; 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.  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.

            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

    (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.

     

    
      
        
        

      

      
        
          38

          
            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

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

     

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

     

    Section 2.17.  Mitigation Obligations; Replacement of
Lenders.  (a) If any Lender requests compensation under 
Section 2.13, or if any Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to

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

     

    (b) If (w) any Lender
requests compensation under 
Section 2.13, or (x) if any Borrower
is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to

Section 2.15, or (y) if any Lender defaults in its obligation to fund Loans
hereunder or (z) any Lender refuses to grant its approval with respect to any
matter requiring the approval of all Lenders and such matter shall have been
approved by the Majority Lenders, then the Company may, at its sole expense and
effort, upon notice to such Lender and the Administrative Agent, require such
Lender to assign and delegate, without recourse (in accordance with and subject
to the restrictions contained in 
Section
10.04), all
its interests, rights and obligations under this Agreement to an assignee that
shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) the Company shall have received the
prior written consent of the Administrative Agent, which consent shall not
unreasonably be withheld, (ii) such Lender shall have received payment of an
amount equal to the outstanding principal of its Loans, participations in LC
Disbursements, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder, from the assignee (to the extent of such outstanding
principal, participations in LC Disbursements and accrued interest and fees) or
the Borrowers (in the case of all other amounts) and (iii) in the case of any
such assignment resulting from a claim for compensation under

Section 2.13 or payments required to be made pursuant to 
Section 2.15, such assignment will result in a reduction in such compensation or
payments.  A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by
such Lender or otherwise, the circumstances entitling the Company to require
such assignment and delegation cease to apply.

stated amount of any issued Letter of Credit), is subject to the satisfaction of
the following conditions:

     

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

Borrower shall have executed and delivered standard documentation for account
parties or reimbursement obligors in connection with the issuances of letters of
credit as is customary for such Issuing Bank and that is not otherwise
inconsistent with the terms of this Agreement.

     

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

Loans to the Borrowers in an amount such that, after giving effect thereto, the
aggregate amount of such Loans shall bear the same relationship to the
Commitment of such New Lender as the outstanding Loans of the other Lenders bear
to their Commitments, such new Loans to be allocated ratably among all
outstanding Borrowings and to be deemed part of such outstanding
Borrowings.

     

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

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

     

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

    The Company, and
each Pipeline Company Borrower, in each case with respect to itself and its

jurisdiction of its organization or formation.  Each Credit Related
Party possesses all applicable Business Entity powers and all other

Section 4.07 (collectively, the “Disclosure Update”), as of the
Effective Date, since December 31, 2006, there has been no Material Adverse
Effect.

     

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

     

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

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

     

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

     

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

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

     

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

     

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

     

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

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

     

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

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

     

    Section
4.14.  Environmental
Matters.  Except for the matters set forth on Schedule 4.14 and

in a Material Adverse Effect, no Credit Related Party (a) has failed to comply
with any Environmental Law or to obtain, maintain or comply with any permit,
license or other approval required under any Environmental Law, (b) is subject
to any Environmental Liability, (c) has received notice of any claim with
respect to any Environmental Liability or (d) knows of any basis for any
Environmental Liability.

of the circumstances under which they were made, not misleading.

     

    Section

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

otherwise becomes aware that such material provision is not valid or is
unenforceable as aforesaid, the Company delivers written notice to the
Administrative Agent that the applicable Credit Party intends to cure such
invalidity or unenforceability as soon as possible, then an Event of Default
shall not exist pursuant to this paragraph (k) of 
Article 7 unless the Company or the relevant Credit Party
shall fail to deliver or cause to be delivered an amendment or other
modification, or other agreement or undertaking, having the same economic effect
as the invalid or unenforceable provision within four Business Days after the
delivery of such written notice of intent; or

     

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

     

    Section
8.01.  Company
Guarantee.

     

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

     

    (b) The guarantee
contained in this

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

     

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

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

     

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

     

    Section
8.04.  Guarantee Absolute and
Unconditional.  The Company waives any and all notice of the
creation, renewal, extension or accrual of any of the Company Guaranteed
Obligations and notice of or proof of reliance by any Agent or any Lender upon the
guarantee contained in this 
Article 8 or acceptance of
the guarantee contained in this 
Article 8; the Company Guaranteed
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred, or renewed, extended, amended or waived, in reliance
upon the guarantee contained in this 
Article 8; and all dealings
between the Company, any of the Pipeline Company

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

     

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

    ARTICLE

    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.

            Third Amended and

    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.

              (ix) if to any other

    (b) Notices and other
communications to the Lenders hereunder may be delivered or furnished by
electronic communications pursuant to procedures approved by the Administrative
Agent; provided that
the foregoing shall not apply to notices pursuant to 
Article 2 unless otherwise agreed by the Administrative Agent and
the applicable Lender.  The Administrative Agent or a Borrower may, in
its discretion, agree to accept notices and other communications to it hereunder
by electronic communications pursuant to procedures approved by it; provided that approval of
such procedures may be limited to particular notices or

other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given and effective, if sent by

Section 10.01 but
received on any day other than a Business Day or after business hours in the

place.

     

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

     

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

     

    
      
        
        

      

      
        
          67

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

     

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

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

     

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

Section 10.03(b) shall limit the liability of any Borrower
for the payment of the Loans or any Secured Obligations, which liability arises
under any other Loan Document, including any liability arising under this
Agreement.

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

     

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

     

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

     

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

     

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

            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

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

     

    (B) the Administrative
Agent; and

     

    (C) each Issuing
Bank.

     

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

     

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

     

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

     

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

     

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

     

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

     

    
      
        
        

      

      
        
          71

          
            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

    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.

            Third Amended and
Restated Credit Agreement

          

        

        
          

        

      

      
        
        

      

    

    (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

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

2.13, 
2.14, 
2.15 and 
10.03 and 
Article 9 shall survive and remain in full force and effect
regardless of the consummation of the transactions contemplated hereby, the
repayment of the Loans, the expiration or termination of the Letters of Credit
and the Commitments or the termination of this Agreement or any provision
hereof.

     

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

     

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

     

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

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

     

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

     

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

     

    (d) Each party to this
Agreement irrevocably consents to service of process in any action or proceeding
referred to in

Section 10.09 by the mailing
thereof by certified mail, return receipt requested, addressed as provided in

Section 10.01(a), with a copy thereof to
the “General Counsel” of such Person at such same address.

     

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

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

     

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

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

     

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

     

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

     

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

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

     

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

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

      


      “Fitch” means Fitch Ratings,
Ltd.

       

      “Level I Pricing” applies on
any day on which the Reference Rating is BBB/Baa2/BBB or higher.

       

      “Level II Pricing” applies on
any day on which the Reference Rating is BBB-/Baa3/BBB-.

       

      “Level III Pricing” applies on
any day on which the Reference Rating is BB+/Ba1/BB+.

      


      “Level IV Pricing” applies on
any day on which the Reference Rating is BB/Ba2/BB.

       

      “Level V 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, Level IV or Level V
Pricing applies on any day.

       

      “Rating Agency” means Fitch,
Moody’s or S&P.

      


      
        
          
            Schedule 3 — Page
1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      The “Reference Rating” is the
credit rating assigned to the Loans by the relevant rating agency; provided that
(i) until such time as Moody's and S&P assigns an initial rating to the
Loans, the Moody's and S&P ratings of the Existing Facility shall be deemed
to be its Reference Rating and (ii) until the Borrowers engage Fitch to rate the
Loans, Fitch's ratings shall be deemed to be unavailable.  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.

       

      In
the event that Reference Ratings are not available from all three Rating
Agencies, (i) if the Reference Rating from Fitch is unavailable, Moody's and
S&P's Reference Ratings shall apply and, if both Reference Ratings from
Moody's and S&P are available but not the same, then (A) if the difference
is one notch, the higher such rating will govern so long as it is at least BBB-
or Baa3 or higher, but the lower rating will govern if that requirement is not
met, and (B) if the difference is more than one notch, a Reference Rating one
notch below the higher of the two will govern; (ii) if the Reference Rating from
either Moody’s or S&P is unavailable, then the Fitch Reference Rating shall
not apply and the Pricing Level will be determined on the basis of the available
Reference Rating from Moody’s or S&P; and (iii) if the Reference Ratings
from both Moody's and S&P are unavailable, then Level V shall
apply.

       

      In
the event Reference Ratings from all three Rating Agencies are available, then
(i) the majority Reference Rating will govern, if two such ratings are the same
or (ii) the middle Reference Rating will govern, if all three such ratings
differ.

       

      If
the rating system of any Rating Agency shall change, the Borrowers and the
Lenders shall negotiate in good faith to amend this Schedule to reflect such
changed rating system and, pending the effectiveness of any such amendment, the
Applicable Rate shall be determined without reference to such Rating
Agency.

      FOR VALUE RECEIVED,
the undersigned, [Name of Borrower], a Delaware corporation (the “Borrower”) hereby
unconditionally promises to pay to the order of _____ (the “Lender”) at the office of
JPMorgan Chase Bank, N.A., located at 270 Park Avenue, New York, New York 10017,
in lawful money of the United States of America and in immediately available
funds, the principal amount of the lesser of (a) _________ ($_______), and (b)
the aggregate unpaid principal amount of all Loans made by the Lender to the
undersigned pursuant to Section 2.02 of the Credit Agreement (as defined
below), on the Maturity Date (as defined in the Credit Agreement) and on such
other dates and in such other amounts set forth in the Credit
Agreement.

       

      The undersigned
further agrees to pay interest in like money at such office on the unpaid
principal amount hereof from time to time from the date hereof at the applicable
rate per annum set forth in Section 2.11 of the Credit Agreement until any
such amount shall become due and payable (whether at the stated maturity, by
acceleration or otherwise), and thereafter on such overdue amount at the rate
per annum set forth in paragraph (c) of Section 2.11 of the Credit
Agreement until paid in full (both before and after
judgment).  Interest shall be payable in arrears on each Interest
Payment Date commencing on the first such date to occur after the date hereof,
provided that interest accruing pursuant to paragraph (c) of Section 2.11
of the Credit Agreement shall be payable on demand.  In no event shall
the interest payable hereon, whether before or after maturity, exceed the
maximum interest which, under applicable law, may be charged on this Note, and
this Note is expressly made subject to the provisions of the Credit Agreement
which more fully set out the limitations on how interest accrues
hereon.

       

      The holder of this
Note is authorized to record the date, type and amount of each Loan made by the
Lender pursuant to Section 2.02 of the Credit Agreement, each continuation
thereof, each conversion of all or a portion thereof to another type, the date
and amount of each payment or prepayment of principal with respect thereto, and,
in the case of Eurodollar Loans, the length of each Interest Period with respect
thereto, on the schedules annexed hereto and made a part hereof, or on a
continuation thereof which shall be attached hereto and made a part hereof,
which recordation shall constitute prima facie evidence of the
accuracy of the information recorded in the absence of manifest error; provided that failure by the
Lender to make any such recordation on this Note shall not affect the
obligations of the Borrower under this Note or the Credit
Agreement.

       

      This Note is one of
the Notes referred to in the Third Amended and Restated Credit Agreement, dated
as of November 16, 2007 (as amended, supplemented or otherwise modified from
time to time, the “Credit
Agreement”), among the Borrower, [the Company], [EPNGC] and [TGPC], the
Lender, the other financial institutions parties thereto, and JPMorgan Chase
Bank, N.A., as administrative agent and as collateral agent, is entitled to the
benefits thereof, is secured as provided therein and in the Security Documents
and is subject to optional and mandatory prepayment in whole or in part as
provided therein.  Terms used herein which are defined in the Credit
Agreement shall have such defined meanings unless otherwise defined herein or
unless the context otherwise requires.

       

      Upon the occurrence
of any one or more of the Events of Default specified in the Credit Agreement,
all amounts then remaining unpaid on this Note shall become, or may be declared
to be, immediately due and payable all as provided therein.

       

      This Note and the
other Notes are given in replacement and substitution for, but not payment or
satisfaction of, certain revolving credit notes previously issued under the
Credit Agreement.  The indebtedness evidenced by such other revolving
credit notes is continued in full force and effect hereunder.

       

      THIS
NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

       

      This Note evidences
existing indebtedness under the Credit Agreement and does not constitute payment
of such indebtedness, and such indebtedness continues in full force and effect,
as amended and restated in the Credit Agreement.

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

and warranties made by the Credit Parties herein, and in any other Security
Document delivered pursuant hereto, shall survive the execution and delivery by
the Credit Parties of the Security Documents.  The Credit Parties
shall deliver to the Collateral Agent amended and restated schedules (the “Amended Schedules”) to this
Agreement in the event that any information contained on the schedules attached
hereto becomes inaccurate.  Such Amended Schedules shall replace the
schedules provided by the Credit Parties on the Effective Date, and shall be

name, identity, corporate structure (including, without limitation, its
jurisdiction of formation) or the location of its registered office without (i)
giving the Collateral Agent at least 10 Business Days’ prior written notice
clearly describing such new name, identity, corporate structure or new location
and providing such other information in connection therewith as the Collateral
Agent may reasonably request, and (ii) taking all action satisfactory to the
Collateral Agent at the expense of such Credit Party as the Collateral Agent may
request to maintain the security interest of the Collateral Agent in the
Collateral intended to be granted hereby at all times fully perfected with the
same priority and in full force and effect.

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

       

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

       

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

       

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

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

       

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

       

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

       

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

       

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

       

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

       

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

            Exhibit D

            Third Amended and
Restated Credit Agreement

          

          
            

          

        

        
          
          

        

      

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

       

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

       

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

       

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

       

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

            Exhibit D

            Third Amended and
Restated Credit Agreement

          

          
            

          

        

        
          
          

        

      

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

       

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

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

       

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

       

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

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

       

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

       

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

       

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

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

       

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

       

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

       

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

       

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

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

       

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

       

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

       

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

       

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

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

       

      (c) The Depository Bank
(i) has identified (and will continue to identify) the Collateral Agent for the
ratable benefit of the Secured Parties in its records as, and will treat the
Collateral Agent as (A) the sole Person having a security entitlement against
the Depository Bank with respect to the Pledged Accounts and the Account

Agent that such issuer will comply with instructions with respect to such
Security Collateral originated by the Collateral Agent without further consent
of such Grantor, such authenticated record to be in form and substance

respect to any Security Collateral in which any Grantor has any right, title or
interest and that is not an uncertificated security, upon the request of the
Collateral Agent, such Grantor will notify each such issuer of Pledged Equity
that such Pledged Equity is subject to the security interest granted
hereunder.

       

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

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

obligations under limited liability company agreements, limited partnership
agreements and any other organizational or constituent documents pursuant to
which Pledged Equity has been issued or which sets out obligations with respect
to Security Collateral) to the extent set forth therein to perform all of its
duties and obligations thereunder to the same extent as if this Agreement had
not been executed, (b) the exercise by the Collateral Agent of any of the rights
hereunder shall not release any Grantor from any of its duties or obligations

Party shall have any obligation or liability under the contracts and agreements
included in the Collateral by reason of this Agreement or any other Security
Document, nor shall any Secured Party be obligated to perform any of the
obligations or duties of any Grantor thereunder or to take any action to collect
or enforce any claim for payment assigned hereunder.

the Equity Interests in any Grantor that is a Pledged Company.

       

      (c) Ownership of Equity Interests in
Pledged Companies.  Each Grantor (including any successor

all cash dividends, interest and other cash distributions paid in respect of the
Security Collateral of such Grantor;

       

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

       

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

       

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

Grantor to exercise or refrain from exercising the voting and other consensual
rights that it would otherwise be entitled to exercise pursuant to Section

written notice of such Event of Default, cease, and all such rights shall
thereupon become vested in the Collateral Agent, which shall thereupon have the
sole right to exercise or refrain from exercising such voting and other
consensual rights;

       

      (ii) all rights of each
Grantor to receive the dividends, interest and other distributions that it would
otherwise be authorized to receive and retain pursuant to Section 5.08(a)(ii)
shall, upon delivery by the Collateral Agent to such Grantor of a written notice

delivered to the Collateral Agent who shall cause the Depository Bank to deposit
same in a subaccount of the Cash Collateral Account to be administered in

Pledged Equity that is a party to this Agreement, upon delivery by the
Collateral Agent to such issuer of a written notice of such Event of Default,
such issuer shall thereafter pay and deliver all dividends, distributions and
interest described in this Section 5.08(d)(ii) directly to the Collateral Agent,
until such issuer has received written notice from the Collateral Agent that
such Event of Default no longer exists.  Each Grantor that has granted
a security interest in Pledged Equity under this Agreement in an issuer that is
not a party to this Agreement, agrees to cause such issuer to pay and deliver
all dividends, distributions and interest described in this Section 5.08(d)(ii)
directly to the Collateral Agent.  Any such dividends, interest and
distributions received by a Grantor contrary to the provisions of this Section
5.08(d)(ii) shall be received in trust for the benefit of the Collateral Agent,

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

paid over by such Grantor to the Collateral Agent who shall cause the Depository
Bank to deposit same in a subaccount of the Cash Collateral Account to be

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

and in continuing, any Credit Related Party may reduce (through the exercise of
set-off or similar rights) the principal amount of any accounts, payment
intangibles, instruments or chattel paper owed by it to another Credit Related
Party by the amount of any accounts, payment intangibles, instruments or chattel
paper owed to it or any of its Subsidiaries by such other Credit Related Party

      (ii) Sale; Incidents of

Obligations shall then be due and payable) shall be entitled and empowered (but
not obligated), by intervention in such proceeding or otherwise, (A) to file and
prove a claim for the whole amount of the Secured Obligations owing and unpaid

and under the Security Documents, and the Collateral Agent shall take such
action solely as agent for the Secured Parties.

Proceeds.  If an Event of Default shall have occurred and be

Accounts or (ii) the proceeds of any Disposition of all or any part of the
Collateral, such cash and/or proceeds shall be applied to the Secured

full and all Letters of Credit shall have been Cash Collateralized;

       

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

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

       

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

       

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

the other Security Documents or the performance by the Credit Parties hereto and
thereto of their respective obligations hereunder and thereunder, except in each
case of clause (i) and (ii), as to any particular Indemnified Party, to the
extent such claim, damage, loss, liability or expense is found in a final,
nonappealable judgment by a court of competent jurisdiction to have resulted
from, or to be attributable to, the gross negligence or willful misconduct of
such Indemnified Party or its employees or agents.  The
indemnification provisions of this Section 9.01(a) are not intended to

commitment fees, rental or other lease payments, or analogous amounts, under any

Documents, (ii) the custody, preservation, or the sale of, collection from or
other realization upon, any of the Collateral of such Credit Party, (iii) the

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

other obligations of any other Credit Party under or in respect of the Financing
Documents, and a separate action or actions may be brought and prosecuted by the

other Security Document to which such Credit Party is a party, irrespective of
whether any action is brought against the Company or any other Credit Party or
whether the Company or any other Credit Party is joined in any such action or
actions.  All rights of the Collateral Agent and the other Secured
Parties and the Liens granted by the Grantors hereunder, and all obligations of
each Credit Party hereunder, shall be unaffected by, and each Credit Party
hereby irrevocably waives (to the maximum extent permitted by applicable law)

have or may hereafter acquire, which defenses in any way relate to, any or all

such case the Credit Parties and the Secured Parties shall, subject to any
effect of or determination in such proceeding, severally and respectively be

irrevocably and unconditionally agrees that all claims in respect of any such
action or proceeding may be heard and determined in such New York State court

Secured Party may otherwise have to bring any action or proceeding relating to
this Agreement, the Security Documents or any of the other Financing Documents

      (b) Each of the parties
irrevocably and unconditionally waives, to the fullest extent it may legally and

court referred to in this Section.  Each of the parties hereto

      (d) The guarantee
contained in this Article 2 shall remain in full force and effect until the

full in cash.

       

      (e) No payment or

Subsidiary Guarantors, any other guarantor or any other Person, or received or
collected by the Collateral Agent or any Secured Party from the Company, any

      Section
2.02.  Right of
Contribution.  Each Subsidiary Guarantor hereby agrees that to

of this Section 2.02 shall in no respect limit the obligations and liabilities
of any Subsidiary Guarantor to the Collateral Agent and the Secured Parties, and

      Section
2.03.  No
Subrogation.  Notwithstanding any payment made by any

Collateral Agent or any Secured Party against the Company or any other
Subsidiary Guarantor or any collateral security or guarantee or right of offset
held by the Collateral Agent or any Secured Party for the payment of Guaranteed

contribution or reimbursement from the Company or any other Subsidiary Guarantor
in respect of payments made by such Subsidiary Guarantor hereunder, until the

Guarantor on account of such subrogation rights prior to the Guarantee Release
Date, such amount shall be held by such Subsidiary Guarantor in trust for the
Collateral Agent and the Secured Parties, segregated from other funds of such
Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary
Guarantor, be turned over to the Collateral Agent in the exact form received by
such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the
Collateral Agent, if required), to be applied against Guaranteed Obligations,
whether matured or unmatured, in accordance with the terms and provisions of the
Credit Agreement and Security Agreement.

      Section
2.04.  Amendments, Etc. With
Respect to the Guaranteed Obligations.  Each Subsidiary
Guarantor shall remain obligated under this Article 2 notwithstanding that,
without any reservation of rights against such Subsidiary Guarantor and without
notice to or further assent by such Subsidiary Guarantor, (a) any demand for
payment of any of the Guaranteed Obligations made by the Collateral Agent or any
other Secured Party may be rescinded by the Collateral Agent or any other
Secured Party and any of the Guaranteed Obligations continued, (b) any
Guaranteed Obligations, or the liability of any other Person upon or for any
part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Collateral Agent or any Secured Party, and (c)
the Credit Agreement or the other Financing Documents and any other documents
executed and delivered in connection therewith, in each case may be amended,
modified, supplemented or terminated, in whole or in part, pursuant to the terms
and conditions of each such applicable document from time to time, and any
collateral security, guarantee or right of offset at any time held by the
Collateral Agent or any other Secured Party for the payment of any Guaranteed
Obligations may be sold, exchanged, waived, surrendered or
released.

       

      Section
2.05.  Guarantee Absolute And
Unconditional.  Each Subsidiary Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Guaranteed
Obligations and notice of or proof of reliance by the Collateral Agent or any
other Secured Party upon the guarantee contained in this Article 2 or acceptance
of the guarantee contained in this Article 2.  Each Subsidiary
Guarantor waives diligence, presentment, protest, demand for payment, notice of
intent to accelerate, notice of acceleration and notice of default or nonpayment
to or upon the Company, any Pipeline Company Borrower or any of the Subsidiary
Guarantors with respect to Guaranteed Obligations.  Each Subsidiary
Guarantor understands and agrees that the guarantee contained in this Article 2
shall be construed as a continuing, absolute, irrevocable and unconditional
guarantee of payment without regard to (a) the validity or enforceability or
perfection of the Credit Agreement or any other Financing Document, any of the
Guaranteed Obligations or any other collateral security therefor or guarantee or
right of offset with respect thereto at any time or from time to time held by
the Collateral Agent or any Secured Party, (b) any defense, set-off or
counterclaim whatsoever (other than a defense of payment or performance) which
may at any time be available to or be asserted by the Company or any other
Person against the Collateral Agent or any other Secured Party, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of the Company
or such Subsidiary Guarantor or any other Credit Party), other than payment or
performance, which constitutes, or might be construed to constitute, an
equitable or legal discharge of the Company, any Pipeline Company Borrower or
any other Subsidiary Guarantor for any of its respective portion of the
Guaranteed Obligations or of such Subsidiary Guarantor under the guarantee
contained in this Article 2, in bankruptcy or in any other
instance.  When making any demand hereunder or otherwise pursuing its
rights and remedies hereunder against any Subsidiary Guarantor, the Collateral
Agent 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 the Company,
any Pipeline Company Borrower, any other Subsidiary Guarantor or any other
Person or against any collateral security or guarantee for the Guaranteed
Obligations or any right of offset with respect thereto, and any failure by the
Collateral Agent to make any such demand, to pursue such other rights or
remedies or to collect any payments from the Company, any Pipeline Company
Borrower, any other 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 the Company, any Pipeline Company Borrower, any other
Subsidiary Guarantor or any other Person or any such collateral security,
guarantee or right of offset, shall not relieve such Subsidiary Guarantor 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 the
Collateral Agent against such Subsidiary Guarantor.  For the purposes
hereof “demand” shall
include the commencement and continuance of any legal proceedings.

any of the Guaranteed Obligations is rescinded or must otherwise be restored or
returned by the Collateral Agent or any Secured Party 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

3.03.  No Waiver By Course of
Conduct; Cumulative Remedies.  Neither the Collateral Agent nor
any other Secured Party shall by any act (except by a written instrument in
accordance with Section 3.01), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default.  No failure to exercise, nor any delay in exercising, on the
part of the Collateral Agent or any Secured Party, any right, power or privilege
hereunder shall operate as a waiver thereof.  No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or
privilege.  A waiver by the Collateral Agent or any Secured Party of
any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Collateral Agent or any Secured Party would
otherwise have on any future occasion.  The rights and remedies herein
provided are cumulative, may be exercised singly or concurrently and are not
exclusive of any other rights or remedies provided by law.

losses, liabilities and expenses (including reasonable fees and expenses of
counsel) that may be incurred by or asserted or awarded against any Indemnified
Party, in each case arising out of or in connection with or as a result of the
execution or delivery of this Agreement or the performance by the Subsidiary
Guarantors of their respective obligations hereunder, except to the extent such
claim, damage, loss, liability or expense is found in a final, nonappealable
judgment by a court of competent jurisdiction to have resulted from, or to be
attributable to, the gross negligence or willful misconduct of such Indemnified
Party or its employees or agents.

       

      (b) Each Subsidiary
Guarantor (without duplication) will pay to the Collateral Agent the amount of

expenses of its counsel and of any experts and agents, that the Collateral Agent
may incur in connection with (i) the administration of this Agreement, (ii) the
exercise or enforcement of any of the rights of the Collateral Agent or any
other Secured Party hereunder or (iii) the failure by such Subsidiary Guarantor
to perform or observe any of the provisions hereof required to be performed or
observed by it.

      (c) Each Subsidiary
Guarantor (without duplication) shall pay or reimburse the Collateral Agent for
any transfer taxes or other taxes relating to or incurred in connection with
this Agreement and shall indemnify and hold harmless the Collateral Agent and
each other Secured Party from any amounts that it is obligated to pay in the way
of such taxes.

       

      (d) Each Subsidiary
Guarantor (without duplication) agrees to indemnify and hold harmless the
Collateral Agent (in its agency capacity), and each other Secured Party from,
and shall reimburse the Collateral Agent (in its agency capacity) and each other
Secured Party for any present or future claim for liability for any stamp or
other similar tax and any penalties or interest with respect thereto, which may
be assessed, levied or collected by any jurisdiction in connection with this
Agreement.

       

      (e) The indemnities and
reimbursement provided by the Subsidiary Guarantors pursuant to this Agreement
shall survive the expiration, cancellation, termination or modification of this
Agreement, the resignation or removal of the Collateral Agent, and the provision
of any subsequent or additional indemnity or any agreement to reimburse by any
Person.

       

      (f) All amounts due
under this Section 3.04 shall be payable not later than 30 days after the
delivery of written demand to the applicable Subsidiary Guarantor

Assigns.  This Agreement shall be binding upon the successors
and assigns of each Subsidiary Guarantor and shall inure to the benefit of the

connection with a transaction expressly permitted by Section 6.05 of the Credit
Agreement, no Subsidiary Guarantor may assign, transfer or delegate any of its
rights or obligations under this Agreement without the prior written consent of
the Collateral Agent.

       

      Section
3.06.  Set-Off.  Each
Subsidiary Guarantor hereby irrevocably authorizes the Collateral Agent and each
Secured Party at any time and from time to time while an Event of Default shall
have occurred and be continuing, without prior notice to such Subsidiary
Guarantor or any other Subsidiary Guarantor, any such notice being expressly
waived by each Subsidiary Guarantor, to set-off and appropriate and apply any
and all deposits (general or special, time or demand, provisional or final), in
any currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by the Collateral Agent or such Secured
Party to or for the credit or the account of such Subsidiary Guarantor, or any
part thereof in such amounts as the Collateral Agent or such Secured Party may
elect, subject in all respects to the terms and provisions of the Credit
Agreement, against and on account of the obligations and liabilities of such
Subsidiary Guarantor to the Collateral Agent or such Secured Party hereunder or
under the other Loan Documents and claims of every nature and description of the
Collateral Agent or such Secured Party against such Subsidiary Guarantor, in any
currency, whether arising hereunder, under the Credit Agreement or any other
Loan Document, as the Collateral Agent or such Secured Party may elect, subject
in all respects to the terms and provisions of the Credit Agreement, whether or
not the Collateral Agent or such Secured Party has made any demand for payment
and although such obligations, liabilities and claims may be contingent or
unmatured.  The Collateral Agent or the applicable Secured Party shall
notify such Subsidiary Guarantor promptly of any such set-off and the
application made by the Collateral Agent or such Secured Party of the proceeds
thereof, provided that
the failure to give such notice shall not affect the validity of such set-off
and application.  The rights of the Collateral Agent and the Secured
Parties under this Section 3.06 are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which the Collateral
Agent and the Secured Party may have under Applicable Law pursuant to the terms
and provisions of the Credit Agreement.

is a party, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the Supreme Court of the
State of New York, sitting in New York County, the courts of the United States
of America for the Southern District of New York, and appellate courts from any

      (b) consents that any
such action or proceeding may be brought in such courts and waives any objection

in Section 3.02 or at such other address of which the Collateral Agent shall
have been notified pursuant thereto;

       

      (d) agrees that nothing
herein shall affect the right to effect service of process on it in any other
manner permitted by law or shall limit the right to sue in any other
jurisdiction; and

       

      (e) waives, to the
maximum extent not prohibited by law, any right it may have to claim or recover
in any legal action or proceeding referred to in this Section 3.12 any special,
indirect, exemplary, punitive or consequential damages.

       

      Section

On the Guarantee Release Date this Agreement and all obligations (other than
those expressly stated to survive such termination and in all cases subject to
Section 2.06 hereof) of each Subsidiary Guarantor and any other party hereto
shall terminate, all without delivery of any instrument or performance of any
act by any Person.  At the request and sole expense of the Company or
any Subsidiary Guarantor following any such termination, the Collateral Agent
shall promptly execute and deliver to the Company or such Subsidiary Guarantor,
as the case may be, such agreements, instruments and other documents as such
Subsidiary Guarantor shall reasonably request to evidence such
termination.

       

      (b) On the date hereof,
without further action by any party to this Agreement or the Existing Subsidiary
Guarantee Agreement, each of the Released Parties shall cease to be a Subsidiary
Guarantor under the Existing Subsidiary Guarantee Agreement, and shall not be
deemed a Subsidiary Guarantor under this Agreement.

Enforcement; Demand Not Required.  Notwithstanding any other
provision of this Agreement, no Secured Party other than the Collateral Agent
shall have the right to take any Enforcement Action with respect to this
Agreement and all such Enforcement Actions shall be effected solely through the
Collateral Agent.  No reference in this Agreement to the Collateral
Agent’s making a demand for payment under this Agreement shall be construed to
mean that such a demand is required in order to cause any obligation under this
Agreement to become due and payable, it being understood that obligations under
this Agreement shall become due and payable as, and at such time as, provided in
Section 2.01(a).

      Re:  El
Paso Corporation $1,500,000,000 Revolving Credit Facility

       

      Ladies and
Gentlemen:

       

      We
have acted as special counsel for El Paso Corporation (“El Paso”), Tennessee Gas
Pipeline Company and El Paso Natural Gas Company, each a Delaware corporation
(collectively, the “Borrowers”), and El Paso EPNG
Investments, L.L.C., a Delaware limited liability company, El Paso Tennessee
Pipeline Co., a Delaware corporation, and El Paso TGPC Investments, L.L.C., a
Delaware limited liability company (collectively, the “Subsidiary Guarantors” and together with
the Borrowers, the “Opinion

Agreement dated as of November __, 2007 (the “Credit Agreement”) among the
Borrowers, JPMorgan Chase Bank, N.A. (“JPMorgan”), as Administrative
Agent (in such capacity, the “Administrative Agent”),
JPMorgan, as Collateral Agent (in such capacity, the “Collateral Agent”) and the
lenders party thereto (the “Lenders”).  This
opinion letter is delivered to you pursuant to Section 3.01(b)(vi) of the Credit
Agreement.

       

      Capitalized terms
used herein and not otherwise defined herein shall have the meanings assigned to
such terms in the Credit Agreement.  As used herein, (i) “Opinion Documents” means (A)
the Credit Agreement, (B) the Subsidiary Guarantee Agreement, (C) the Security
Agreement and (D) the UCC Financing Statements (as defined below), (ii) “New York UCC” means the
Uniform Commercial Code as in effect in the State of New York, and (iii) “Applicable Law” means those
laws, rules, and regulations of the State of New York and of the United States
of America as in effect on the date hereof which in our experience are normally
applicable to the Opinion Parties and to transactions of the type provided for
in the Opinion Documents and of the Uniform Commercial Code as in effect in the
State of Delaware (the “Delaware UCC”); provided, however, that Applicable Law
does not include (i) except with respect to our opinions in paragraphs 4 and 5

and regulations relating to the environment, safety, health, or other similar
matters; (v) building, zoning, land use and subdivision laws and regulations;
(vi) any federal or state tax laws or regulations; and (vii) any federal or

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      In
connection with the opinions expressed herein, we have examined such documents,
records and matters of law as we have deemed necessary for the purposes of such
opinions.  We have examined an executed copy of the Opinion
Documents.

       

      In
all such examinations, we have assumed the legal capacity of all natural persons
executing documents, the genuineness of all signatures, the authenticity of
original and certified documents, and the conformity to original or certified
copies of all copies submitted to us as conformed or reproduction copies. As to
various questions of fact relevant to the opinions expressed herein, we have
relied upon, and assumed the accuracy of, representations and warranties
contained in the Opinion Documents and certificates and oral or written
statements and other information of or from representatives of the Opinion
Parties and others and assumed compliance on the part of the Opinion Parties
with its covenants and agreements contained therein.

       

      Based upon the
foregoing, and subject to the limitations, qualifications and assumptions set
forth herein, we are of the opinion that:

       

      1. 1.             Approvals; Other Required
Actions.  The execution and delivery by each of the Opinion
Parties of each Opinion Document to which it is a party and the performance by
each Opinion Party of its obligations thereunder, do not require under
Applicable Law any filing or registration by such Opinion Party with, or notice
to or approval, consent, authorization or order of, any Governmental Authority
that has not been made or obtained, except those filings (a) required to perfect
security interests, if any, granted by such Opinion Party thereunder, (b) those
filings required pursuant to securities and other laws that may be applicable to
the disposition of any collateral subject thereto, and (c) filings,
registrations, consents or approvals in each case not required to be made or
obtained by the date hereof.

       

      2. 2.             Enforceability.  Each
Opinion Document constitutes a valid and binding agreement of each Opinion Party
thereto, enforceable against such Opinion Party in accordance with its
terms.

       

      3. 3.             
“No
Violation.”  The execution and delivery by each of the Opinion
Parties of each Opinion Document to which it is a party and the performance of
its obligations thereunder, do not violate or otherwise constitute a default
under (a) any Applicable Law, (b) any provision of any other Opinion Document or
(c) any of the agreements identified in the attached Schedule I; provided that
we express no opinion with respect to any violation arising under or based upon
any cross default provision insofar as it relates to a default under an
agreement not identified to us, or arising under or based upon any covenant or
other provision of a financial or numerical nature or requiring
computation.

       

      4. 4.             Margin
Regulations.  The borrowings by the Borrowers under the Credit
Agreement and the application of the proceeds thereof as provided in the Credit
Agreement will not violate Regulation U or X of the Board of Governors of the
Federal Reserve System (the “Margin
Regulations”).

       

      
        
          
            2

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      5. 5.             Investment Company
Act.  No Opinion Party is required to register as an
“investment company” (under, and as defined in, the Investment Company Act of
1940, as amended).

       

      6. 6.             Creation of Security
Interests.  The provisions of the Security Agreement are
effective to create in favor of the Collateral Agent to secure the obligations
described therein, a valid security interest in all of the right, title and
interests of El Paso and the Subsidiary Guarantors in and to the Collateral (as
defined in the Security Agreement) to the extent that a security interest may be
created under Article 9 of the Uniform Commercial Code as in effect in the State
of New York (the “Article 9
Collateral”).

       

      7. 7.             Central Filing
Perfection.  To the extent that the filing of a financing
statement with the office of the Secretary of State of Delaware can be effective
to perfect a security interest in the Article 9 Collateral under the Delaware
UCC, the security interests in favor of the Collateral Agent in that portion of
the Article 9 Collateral described in such financing statement will be perfected
upon the filing of the financing statements attached as Exhibit A to this
opinion (the “UCC Financing
Statements”) in the office of the Secretary of State of the State of
Delaware.

       

      8. 8.             Delaware
Filing.  Once the UCC Financing Statements are filed as
described in paragraph 7 above, no further or subsequent filing or refiling will
be necessary in the State of Delaware in order to continue the perfection of the
security interest referred to in paragraph 6 above except that (a) continuation
statements with respect to the UCC Financing Statements must be filed under the
Delaware UCC in the office where such statement was filed within six months
prior to the expiration of five years from the date of such filing (or otherwise
within the time permitted by Section 9-515 of the Delaware UCC), and subsequent
continuation statements must be filed within six months prior to the end of each
subsequent five-year period, and (b) amendments or supplements to the UCC
Financing Statements or additional financing statements may be required to be
filed in the event of a change in the name, identity, or structure of any debtor
listed therein or in the event any such financing statement otherwise becomes
inaccurate or incomplete.

       

      9. 9.             Perfection of Security Interests in
Certificated Securities.  Assuming that the certificates
representing the certificated securities (as defined in the New York UCC)
constituting Article 9 Collateral, together with instruments of transfer or
assignment in blank duly executed by an appropriate person, have been delivered
on or prior to the date hereof to the Collateral Agent in the State of New York,
the Collateral Agent has a perfected security interest in such certificated
securities under the New York UCC.

       

      The opinions set
forth above are subject to the following assumptions and qualifications, and
with your permission, all of the following assumptions and statements of
reliance have been made without any independent investigation or verification on
our part except to the extent, if any, otherwise expressly stated, and we
express no opinion with respect to the subject matter or accuracy of the
assumptions or items upon which we have relied.

       

      
        
          
            3

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      (A)           Our
opinions are subject to (i) applicable bankruptcy, insolvency, reorganization,
fraudulent transfer and conveyance, voidable preference, moratorium,
receivership, conservatorship, arrangement or similar laws, and related
regulations and judicial doctrines, affecting creditors’ rights and remedies
generally, (ii) general principles of equity (including, without limitation,
standards of materiality, good faith, fair dealing and reasonableness, equitable
defenses, the exercise of judicial discretion and limits on the availability of
equitable remedies), whether such principles are considered in a proceeding at
law or in equity, and (iii) the qualification that certain provisions of the
Opinion Documents may be unenforceable in whole or in part under the laws
(including judicial decisions) of the State of New York or the United States of
America, but the inclusion of such provisions does not affect the validity as
against the Opinion Parties party thereto of the Opinion Documents as a whole
and the Opinion Documents contain adequate provisions for the practical
realization of the principal benefits provided by the Opinion Documents, in each
case subject to the other qualifications contained in this letter.

       

      (B)           Without
limiting the generality of paragraph (A) above, we specifically express no
opinion as to the validity or enforceability of any provision in the Opinion
Documents:

       

      (i)           providing
that any person or entity may sell or otherwise dispose of, or purchase, any
collateral subject thereto, or enforce any other right or remedy thereunder
(including without limitation any self-help or taking-possession remedy), except
in compliance with the New York UCC and other applicable laws;

       

      (ii)           establishing
standards for the performance of the obligations of good faith, diligence,
reasonableness and care prescribed by the New York UCC or of any of the rights
or duties referred to in Section 9-603 of the New York UCC;

       

      (iii)           relating
to indemnification, contribution, exculpation or release of liability in
connection with violations of any securities laws or statutory duties or public
policy, or in connection with willful, reckless or unlawful acts or gross
negligence or strict liability of the indemnified, released or exculpated party
or the party receiving contribution;

       

      (iv)           providing
that any person or entity may exercise set-off rights other than in accordance
with and pursuant to applicable law;

       

      (vi)           relating
to choice of governing law to the extent that the enforceability of any such
provision is to be determined by any court other than a court of the State of
New York or may be subject to constitutional limitations;

       

      (vii)           purporting
to confer, or constituting an agreement with respect to, personal or subject
matter jurisdiction of United States federal courts to adjudicate any
matter;

       

      (viii)           specifying
that provisions may be waived only in writing, to the extent that an oral
agreement or an implied agreement by trade practice or course of conduct has
been created that modifies any provision of such Opinion Document;

       

      
        
          
            4

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      (ix)           giving
any person or entity the power to accelerate obligations without any notice to
the Opinion Parties;

       

      (x)           providing
that decisions by a party are conclusive or may be made in its sole
discretion;

       

      (xi)           purporting
to create a power of attorney; or

       

      (xii)           providing
for restraints on alienation of property and purporting to render transfers of
such property void and of no effect or prohibiting or restricting the assignment
or transfer of property or rights to the extent that any such prohibition or
restriction is ineffective pursuant to Sections 9-406 through 9-409 of the New
York UCC.

       

      (C)           Our
opinions as to enforceability are subject to the effect of generally applicable
rules of law that:

       

      (i)           provide
that forum selection clauses in contracts are not necessarily binding on the
court(s) in the forum selected; and

       

      (ii)           may,
where less than all of a contract may be unenforceable, limit the enforceability
of the balance of the contract to circumstances in which the unenforceable
portion is not an essential part of the agreed exchange, or that permit a court
to reserve to itself a decision as to whether any provision of any agreement is
severable.

       

      (D)           We
express no opinion as to the enforceability of any purported waiver, release,
variation, disclaimer, consent or other agreement to similar effect (all of the
foregoing, collectively, a “Waiver”) by any Opinion Party
under the Opinion Documents to the extent limited by Sections 9-602 or 9-624 of
the New York UCC or to the extent ineffective under applicable law

       

      (E)           We
have assumed that each Opinion Party is a corporation or limited liability
company, as the case may be, validly existing and in good standing in its
jurisdiction of organization or formation, has all requisite power and
authority, and has obtained all requisite corporate, and governmental
authorizations, consents and approvals, and made all requisite filings and
registrations, necessary to execute, deliver and perform each Opinion Document
to which it is a party, and that such execution, delivery, and performance will
not violate or conflict with any law, rule, regulation, order, decree, judgment,
instrument or agreement binding upon or applicable to it or its properties
(except to the extent noted in paragraph 3 above).  To the extent it
may be relevant to the opinions expressed herein, we have assumed that (i) the
parties to the Opinion Documents have the power to enter into and perform such
documents and to consummate the transactions contemplated thereby and that such
documents have been duly authorized, executed and delivered by such parties,
(ii) each Opinion Document constitutes legal, valid and binding obligations of
the parties thereto (other than the Opinion Parties), and (iii) the execution
and delivery of each Opinion Document by each of the parties thereto (other than
the Opinion Parties to the extent expressly set forth in paragraph 3 above), and
the performance of such party’s obligations thereunder, do not violate and will
not violate or conflict with any law, rule, regulation, order, decree, judgment,
instrument or agreement binding upon or applicable to it or its
properties.

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      (F)           For
purposes of our opinion in paragraph 4 above, we have assumed that (i) neither
the Collateral Agent nor any Lender has or will have the benefit of any
agreement or arrangement (excluding the Opinion Documents) pursuant to which any
extensions of credit to the Borrowers are directly or indirectly secured by
“margin stock” (as defined under the Margin Regulations), (ii) neither the
Collateral Agent nor any Lender nor any of their respective affiliates has
extended or will extend any other credit to the Borrowers directly or indirectly
secured by margin stock and (iii) neither the Collateral Agent nor any Lender
has relied and will rely upon any margin stock as collateral in extending or
maintaining any extensions of credit pursuant to the Opinion Documents, as to
which we express no opinion.

       

      (G)           Our
opinions are limited to those expressly set forth herein, and we express no
opinions by implication.

       

      (H)           We
express no opinion as to the compliance or noncompliance, or the effect of the
compliance or noncompliance, of each of the addressees or any other person or
entity with any state or federal laws or regulations (including, without
limitation, the policies, procedures, guidelines, and practices of any
regulatory authority with respect thereto) applicable to each of them by reason
of their status as or affiliation with a federally insured depository
institution, a financial holding company, a bank holding company, a
state-chartered non-federally insured depository institution, a securities
dealer, an investment company or an insurance company, except as expressly set
forth in paragraphs 4 and 5 above.

       

      (I)           We
express no opinion as to the validity, binding effect or enforceability of any
provisions contained in the Loan Documents which: (i) purports to establish
evidentiary standards; (ii) restricts access to courts or to legal or equitable
remedies or purporting to affect jurisdiction or venue as to
courts;  (iii) relates to delay or omission of enforcement of
remedies; (iv) entitles any party to the appointment of a receiver, to the
extent contrary to applicable law; (v) purports to permit the Administrative
Agent, the Collateral Agent or any Lender or any other person acting on behalf
of the Administrative Agent, Collateral Agent or any Lender to purchase, sell or
otherwise dispose of any property subject thereto except in compliance with
applicable law; (vi) purports to provide standards for the care of property in
possession of any person other than as provided by applicable law; (vii)
purports to irrevocably appoint any person as attorney-in-fact for the Opinion
Parties, or (viii) purports to permit the transfer of securities without
compliance with applicable securities laws.

       

      (J)           We
have made no examination of and express no opinion with respect to (i) titles to
or rights in or descriptions of the properties described in the Loan Documents,
(ii) the priority of any security interest or whether there are of record any
security interests, charges or encumbrances thereon, (iii) the creation,
existence or perfection of any security interests purported to be created under
the Loan Documents or the filing or recording of the Loan Documents or any
financing statements or other instruments relating thereto except as set forth
in paragraphs 6-9 hereof, or (iv) whether the properties described in the
Security Agreement are the properties and interests intended to be encumbered
thereby.

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      (K)           Our
opinions in paragraphs 6-9 are limited to Articles 8 and 9 of the New York UCC
and Article 9 of the Delaware UCC, and therefore such opinions do not address
laws of jurisdictions other than New York and Delaware, except for Articles 8
and 9 of the New York UCC and Article 9 of the Delaware UCC.

       

      (L)           We
are qualified to practice law in the State of New York, and this opinion letter
is limited in all respects to the Applicable Law; however, we are not members of
the bar of the State of Delaware and our opinions as to any matters governed by
the Delaware UCC are based solely upon our review of the Delaware UCC, without
any review or consideration of any decisions or opinions of courts or other
adjudicative bodies or governmental authorities of the State of
Delaware.

       

      (M)           Our
opinions in paragraphs 6-9 are subject to the following assumptions,
qualifications and limitations:

       

      (i)           Insofar
as any of the opinions herein expressed concern the perfection of a security
interest in “proceeds”
(as such term is defined in the Delaware UCC) please be advised that the
continuation of the existence and perfection of such security interest are
limited as provided in Section 9-315 of the Delaware UCC;

       

      (ii)           We
express no opinion as to the perfection of any security interest or other
encumbrance (A) covering any asset to which the Delaware UCC or the New York UCC
is not applicable or (B) covering property acquired by a debtor after the
commencement of a case under the Federal Bankruptcy Code; and

       

      (iii)           We
assume that all filings will be timely made and duly filed as necessary for
perfection (a) in the event of any change in the name, identity or corporate
structure of El Paso or the Subsidiary Guarantors, (b) in the event of a change
in the jurisdiction of formation of El Paso or the Subsidiary Guarantors, (c) in
the event of a change in the location of the Collateral, if applicable, and (d)
to continue and maintain the effectiveness of the original filings.

       

      (iv)           We
express no opinion as to the nature or extent of the rights, or the power to
transfer rights, of any Opinion Party in, or title of El Paso or any Subsidiary
Guarantor to, any collateral under any of the Opinion Documents, or property
purporting to constitute such collateral, or the value, validity, enforceability
or effectiveness for any purpose of any such collateral or purported collateral,
and we have assumed that El Paso and each Subsidiary Guarantor has sufficient
rights in, or power to transfer rights in, all such collateral or purported
collateral for the security interests provided for under the Opinion Documents
to attach.

            Exhibit F-1

            Third Amended and
Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      (v)           We
express no opinion as to the priority of any pledge, security interest,
assignment for security, lien or other encumbrance, as the case may be, that may
be created or purported to be created under the Opinion Documents.

       

      (vi)           In
the case of property that becomes collateral under the Opinion Documents after
the date hereof, Section 552 of the United States Bankruptcy Code limits the
extent to which property acquired by a debtor after the commencement of a case
under the United States Bankruptcy Code may be subject to a lien arising from a
security agreement entered into by the debtor before the commencement of such
case.

       

      (vii)           We
express no opinion as to the enforceability of the security interests under the
Opinion Documents in any item of collateral subject to any restriction on or
prohibition against transfer contained in or otherwise applicable to such item
of collateral or any contract, agreement, license, permit, security, instrument
or document constituting, evidencing or relating to such item, except to the
extent that any such restriction is rendered ineffective pursuant to any of
Sections 9-406 through 9-409, inclusive, of the New York UCC.

       

      (N)           Insofar
as our opinion in paragraph 2 above relates to the enforceability under New York
law of the choice-of-law provision of the Opinion Documents choosing New York
law as the governing law thereof, it is rendered in reliance upon the Act of
July 19, 1984, ch. 421, 1984 McKinney’s Sess. Law of N.Y. 1406 (codified at N.Y.
Gen. Oblig. Law §§ 5-1401, 5-1402 (McKinney 1989) and N.Y. CPLR 327(b) (McKinney
1990) (the “Act”).   Furthermore,
the application of New York law pursuant to the Act to a transaction that has no
contact or only insignificant contact with the parties and the transaction may
raise constitutional and comity issues.  We direct your attention to
Lehman Brothers Commercial
Corporation v. Minmetals International Non-Ferrous Metals Trading
Company, 2000 U.S. Dist. LEXIS 16445 (S.D.N.Y. 2000), in which the court
analyzed the Act and noted that “[i]t remains to be seen, however,
whether a state with no connection to either of the parties or the transactions
could apply its own law, consonant with the Full Faith and Credit Clause [of the
U.S. Constitution], when doing so would violate an important public policy of a
more-interested state.”

       

      The opinions
expressed herein are solely for the benefit of the addressees hereof in
connection with the transaction referred to herein and may not be relied on by
such addressees for any other purpose or in any manner or for any purpose by any
other person or entity other than any Person that may become a Lender after the
date hereof.  This opinion letter is rendered as of the date set forth
above.  We expressly disclaim any obligation to update this letter
after such date.

       

                   Very truly
yours,

      November __,

      To
the Administrative Agent and the Collateral Agent under the

      Credit Agreement
described below and to each

      (1) Lender party to
such Credit Agreement

       

      Re:  Credit
Agreement dated as of November __, 2007

       

      (2) Ladies/Gentlemen:

       

      This opinion letter
is furnished to you in connection with the Third Amended and Restated Credit
Agreement, dated as of November __, 2007 (the “Credit Agreement”), among E1
Paso Corporation, a Delaware corporation (the “Company”), Tennessee Gas
Pipeline Company, a Delaware corporation (“TGPC”), and El Paso Natural
Gas Company, a Delaware corporation (together with the Company and TGPC, the
“Borrowers”), JPMorgan
Chase Bank, N.A. (“JPMorgan”), as Administrative
Agent (in such capacity, the “Administrative Agent”),
JPMorgan, as Collateral Agent (in such capacity, the “Collateral Agent”) and the
lenders party thereto (the “Lenders”).  Unless
the context otherwise requires, all capitalized terms used but not defined
herein have the meanings assigned to such terms in the Credit
Agreement.

       

      I
am Executive Vice President and General Counsel of the Company, and I, or
attorneys under my supervision and direction, have acted as counsel for the
Borrowers and for El Paso EPNG Investments, L.L.C., a Delaware limited liability
company, El Paso Tennessee Pipeline Co., a Delaware corporation, and El Paso
TGPC Investments, L.L.C., a Delaware limited liability company (each, a “Subsidiary Guarantor”, and
collectively, the “Subsidiary
Guarantors” and together with the Borrowers, the “Opinion Parties”) in
connection with the preparation, execution and delivery of the Credit Agreement
and the other Opinion Documents (hereinafter defined).

       

      In
that connection, I, or attorneys under my supervision and direction, have
examined:

       

      
        	
                 
      

              	
                (1)

              	
                an executed
      counterpart of the Credit
Agreement;

              


      

       

      
        	
                 
      

              	
                (2)

              	
                an executed
      counterpart of the Subsidiary Guarantee
  Agreement;

              


      

       

      
        	
                 
      

              	
                (3)

              	
                an executed
      counterpart of the Security Agreement (collectively with the Credit
      Agreement and the Subsidiary Guarantee Agreement, the “Opinion
      Documents”);

            Third Amended and
Restated Credit Agreement

          

          
            

          

        

        
          
          

        

      

      
        	
                 
      

              	
                (4)

              	
                (a) true and
      correct copies of the certificate of incorporation or certificate of
      formation, as the case may be, and by-laws or limited liability company
      agreements, as the case may be, as amended to date, of each Opinion Party
      and (b) a copy of the certificate of good standing of each Opinion Party,
      dated as of a recent date, issued by the Secretary of State of the State
      of Delaware; and

              


      

       

      
        	
                 
      

              	
                (5)

              	
                other
      documents furnished to me by the Opinion Parties pursuant to or in
      connection with the Opinion
Documents.

              


      

       

      I,
or attorneys under my supervision and direction, have also examined the
originals, or copies, certified or otherwise identified to our satisfaction, of
the agreements, instruments and other documents, and all of the orders, writs,
judgments, awards, injunctions and decrees, which affect or purport to affect
each Opinion Party’s ability to enter into and to perform its obligations under
the Opinion Documents. In addition, I, or attorneys under my supervision and
direction, have examined the originals, or copies certified or otherwise
identified to our satisfaction, of such other corporate records of the Opinion
Parties, certificates of public officials and of officers of the Opinion
Parties, and such other agreements, instruments and other documents, as I have
deemed necessary or appropriate as a basis for the opinions hereinafter
expressed. In all such examinations, I, or such attorneys under my supervision
and direction, have assumed the legal capacity of all natural persons executing
agreements and documents, the genuineness of all signatures on original,
certified or reproduction copies of agreements and documents of all parties
(other than, with respect to the Opinion Documents, the Opinion Parties), the
authenticity of original and certified documents and the conformity to original
or certified copies of all copies submitted to such attorneys or me as conformed
or reproduction copies. As to various questions of fact relevant to the opinions
expressed herein, I have relied upon, and assumed the accuracy of,
representations and warranties contained in the Opinion Documents and
certificates and oral or written statements and other information of or from
public officials, officers and/or representatives of the Opinion Parties and
others.

       

      I
have assumed that the parties to the Opinion Documents (other than the Opinion
Parties) have the power to enter into and perform such documents and that each
such document has been duly authorized, executed and delivered by the parties
thereto (other than the Opinion Parties), and constitutes the valid and binding
obligation of each party thereto.

       

      The opinions
expressed below are limited to the Federal laws of the United States and, to the
extent relevant hereto, the General Corporation Law of the State of Delaware and
the Delaware Limited Liability Company Act, each as currently in
effect.  I assume no obligation to supplement this opinion if any
applicable laws change after the date hereof or if I become aware of any facts
that might change the opinions expressed herein after the date
hereof.

       

      Based on the
foregoing and upon such investigation as I, or attorneys under my supervision
and direction, have deemed necessary, and subject to the limitations,
qualifications and assumptions set forth herein, I am of the following
opinion:

       

      
        	
                 
      

              	
                (1)

              	
                Each Opinion
      Party (i) is a corporation duly incorporated or a limited liability
      company duly formed, as the case may be, and validly existing in good
      standing under the laws of the State of Delaware and (ii) possesses all
      the corporate or limited liability company, as applicable, powers and all
      other authorizations and licenses necessary to engage in its business and
      operations as now conducted, which the failure to obtain or maintain would
      have a Material Adverse Effect.

                (a)

              	
                are within
      each Opinion Party’s corporate or limited liability company, as
      applicable, powers and have been duly authorized by all necessary
      corporate or limited liability company, as applicable, action of or by
      such Opinion Party;

                do not and
      will not contravene the Opinion Party’s certificate of incorporation and
      by-laws or certificate of formation and limited liability company
      agreement, as the case may be, as amended to
  date;

                do not and
      will not contravene any U.S. federal law or regulation applicable to the

      referred to in and covered by the opinion of Bracewell & Giuliani LLP
      dated the date hereof and delivered to you in connection with the
      transactions contemplated hereby) or any provision of the General
      Corporation Law of the State of Delaware or the Delaware Limited Liability

Parties.

      or any Delaware governmental authority or regulatory body pursuant to the
      General Corporation Law of the State of Delaware or the Delaware Limited
      Liability Company Act, is required for the due execution, delivery and

      judgment (taking into account the exhaustion of all appeals), would have a
      Material Adverse Effect (provided that this opinion does not address any

      report on Form 10-K for the fiscal year ended December 31, 2006, or the

      EXHIBIT

      ACCEPTABLE
SUBORDINATION PROVISIONS

       

      [NAME OF BORROWER],
a [Delaware] corporation (together with its successors, the “Borrower”), and [NAME OF
LENDER], a [Delaware] corporation (together with its successors, “Lender”), agree for the
benefit of the Senior Debt (as defined below) that all indebtedness evidenced by
this [PROMISSORY NOTE] (this “Note”), including principal,
premium, if any, and interest, and all other amounts payable to Lender hereunder
(including, for all purposes of this Note, any payment in respect of redemption
or purchase or other acquisition hereof) (collectively, the “Subordinated Debt”) shall, to
the extent hereinafter set forth, be subordinate and junior to all Senior
Debt.

       

      Unless and until
all principal of, premium, if any, and interest on, and all other obligations of
the Borrower under, any Senior Debt shall have been paid in full and all
commitments to extend Senior Debt shall have terminated, neither the Borrower
nor any of its Subsidiaries or Affiliates shall make, and Lender shall not
demand, accept or receive, or attempt to collect or commence any legal
proceedings to collect, any direct or indirect payment (in cash or property or
by setoff, exercise of contractual or statutory rights or otherwise) of or on
account of any amount payable on or with respect to this Note (including any
payment in respect of redemption or purchase or other acquisition) or any
interest herein.  Unless and until all principal of, premium, if any,
and interest on, and all other obligations of the Borrower under, the Senior
Debt shall have been paid in full and all commitments to extend Senior Debt
shall have terminated, Lender will not commence or maintain any action, suit or
any other legal or equitable proceeding against the Borrower, or join with any
creditor in any such proceeding, under any insolvency, bankruptcy, receivership,
liquidation, reorganization or other similar law, unless the holders of Senior
Debt shall also join in bringing such proceeding; provided that the foregoing
shall not prohibit Lender from filing a proof of claim or otherwise
participating in any such proceeding not commenced by it.

       

      In
the event of any insolvency or bankruptcy proceedings, and any receivership,
liquidation, reorganization or other similar proceedings in connection
therewith, relative to the Borrower or to its creditors, in their capacity as
creditors of the Borrower, or to substantially all of its property, and in the
event of any proceedings for voluntary liquidation, dissolution or other winding
up of the Borrower, whether or not involving insolvency or bankruptcy,
then:

       

      (a)      the
holders of the Senior Debt shall first be entitled to receive payment in full of
the principal thereof, premium, if any, interest and all other amounts payable
thereon (accruing before and after the commencement of the proceedings, whether
or not allowed or allowable as a claim in such proceedings) before Lender is
entitled to receive any payment on account or in respect of Subordinated Debt;
and

       

      (b)      any
payment or distribution of assets of the Borrower of any kind or character,
whether in cash, property or securities to which Lender would be entitled, but
for the provisions of this Note, shall be paid or distributed by the liquidating
trustee or agent or other person making such payment or distribution, whether a
trustee in bankruptcy, a receiver or liquidating trustee or other trustee or
agent, directly to the Agent (as defined below) and any other representative on
behalf of the holders of Senior Debt to the extent necessary to make payment in
full of all amounts of Senior Debt remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of the Senior
Debt.

       

      
        
          
            Exhibit G –

Restated Credit Agreement

          

        

        
          
          

          
            

          

        

        
          
          

        

      

      Should any payment
or distribution or security or the proceeds of any thereof be collected or
received by Lender in respect of the Subordinated Debt, at a time when the
payment thereof by the Borrower is prohibited by the terms of this Note, Lender
will forthwith deliver the same to the Agent and any other representative on
behalf of the holders of Senior Debt for the equal and ratable benefit of the
holders of the Senior Debt in precisely the form received (except for the
endorsement or the assignment of or by Lender where necessary) for application
to payment of all Senior Debt in full, after giving effect to any concurrent
payment or distribution to the holders of Senior Debt and, until so delivered,
the same shall be held in trust by Lender as the property of the holders of the
Senior Debt.

       

      Lender shall not be
subrogated to the rights of the holders of the Senior Debt to receive payments
or distributions of assets of the Borrower until all amounts payable with
respect to the Senior Debt shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which Lender would be entitled except for
these provisions shall, as between the Borrower, its creditors other than the
holders of the Senior Debt, and Lender, be deemed to be a payment by the
Borrower to or on account of the Senior Debt.  The subordination
provisions of this Note are and are intended solely for the purpose of defining
the relative rights of Lender, on the one hand, and the holders of the Senior
Debt, on the other hand.

       

      Subject to the
payment in full of all of the Senior Debt, Lender shall be subrogated to the
rights of the holders of Senior Debt to receive payments or distributions of
cash, property or securities of the Borrower applicable to the Senior Debt until
all amounts owing on the Subordinated Debt shall be paid in full.  For
purposes of such subrogation, no payments or distributions to Lender of cash,
property, securities or other assets by virtue of the subrogation herein
provided which otherwise would have been made to the holders of the Senior Debt
shall, as between the Borrower, its creditors other than the holders of Senior
Debt and Lender, be deemed to be a payment to or on account of the Subordinated
Debt.  Lender agrees that, in the event that all or any part of any
payment made on account of the Senior Debt is recovered from the holders of
Senior Debt as a preference, fraudulent transfer or similar payment under any
bankruptcy, insolvency or similar law, any payment or distribution received by
Lender on account of the Subordinated Debt at any time after the date of the
payment so recovered, whether pursuant to the right of subrogation provided for
in this Subordinated Note or otherwise, shall be deemed to have been received by
Lender in trust as the property of the holders of the Senior Debt and Lender
shall forthwith deliver the same to the Agent and any other representative on
behalf of the holders of the Senior Debt for the equal and ratable benefit of
the holders of the Senior Debt for application to payment of all Senior Debt in
full.

the Subordinated Debt:

       

      (i)      the
obligation and liabilities of the Borrower or any other party or parties for or
upon the Senior Debt (or any promissory note, security document or guaranty
evidencing or securing the same) may, from time to time, in whole or in part, be
renewed, extended, modified, amended, restated, accelerated, compromised,
supplemented, terminated, sold, exchanged, waived or released;

       

      (ii)      the
Agent and the holders of the Senior Debt may exercise or refrain from exercising
any right, remedy or power granted by or in connection with any agreements
relating to the Senior Debt; and

       

      (iii)                 any
balance or balances of funds with any holders of the Senior Debt at any time
standing to the credit of the Borrower may, from time to time, in whole or in
part, be surrendered or released;

       

      all as the Agent or
the holders of the Senior Debt may deem advisable and all without impairing,
abridging, diminishing, releasing or affecting the subordination of the
Subordinated Debt to the Senior Debt provided for herein.

       

      Nothing contained

holders of the Senior Debt.

       

      Lender acknowledges
and agrees that the holders of the Senior Debt have relied upon and will
continue to rely upon the subordination provided for herein in entering into the
agreements relating to Senior Debt and in extending credit to the Borrower
pursuant thereto.

       

      No
present or future holder of Senior Debt shall be prejudiced in his right to
enforce the subordination contained herein in accordance with the terms hereof
by any act or failure to act on the part of the Borrower or
Lender.  The subordination provisions contained herein are for the
benefit of the holders of the Senior Debt from time to time and, so long as any
Senior Debt is outstanding under any agreement, may not be rescinded, cancelled
or modified in any way without the prior written consent thereto of all holders
of Senior Debt.

       

      Notwithstanding
anything to the contrary in this Note, upon any payment or distribution of
assets of the Borrower in any proceedings for reorganization, insolvency,
liquidation, dissolution or other winding up, Lender shall be entitled to rely
upon any final order or decree made by any court of competent jurisdiction in
which any such proceedings are pending for the purpose of ascertaining the
persons entitled to participate in such payment or distribution, the holders of
the Senior Debt and other debt of the Borrower, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto.
