Exhibit 10.T.1

AMENDMENT NO. 1 TO THE

EL PASO CORPORATION

2005 OMNIBUS INCENTIVE COMPENSATION PLAN

(as amended and restated)

     WHEREAS, El Paso Corporation (the “Company”) maintains the El Paso Corporation 2005 Omnibus
Incentive Compensation Plan, as amended and restated effective May 6, 2009 (the “Plan”); and

     WHEREAS, pursuant to Section 19.1 of the Plan, the Board of Directors may amend the Plan, in
whole or in part; and

     WHEREAS, it is hereby intended that the Plan be amended to permit the settlement of stock
appreciation rights in cash and to incorporate minimum vesting restrictions applicable to Other
Stock-Based Awards (as such term is defined in the Plan).

     NOW, THEREFORE, the Plan is amended as follows:

	 	1.	 	Section 7.2 is amended by revising the second sentence thereof to read as follows:
	 
	 	 	 	“Upon exercise of a stock appreciation right, a Participant shall be
entitled to receive payment from the Company in an amount determined by
multiplying (i) the difference between the Fair Market Value of a share of
Common Stock on the date of exercise of the stock appreciation right over
the price fixed at the date of grant (which price shall not be less than
100% of the Fair Market Value of a share of Common Stock on the date of
grant) times (ii) the number of shares of Common Stock with respect to which
the stock appreciation right is exercised.”
	 
	 	2.	 	Section 7.2 is further amended by replacing the final sentence thereof with the
following:
	 
	 	 	 	“At the discretion of the Plan Administrator, the payment upon stock
appreciation right exercise may be in cash, in shares of Common Stock of
equivalent value, or in some combination thereof.”
	 
	 	3.	 	Section 12.2 is amended by adding the following sentences to the end thereof:
	 
	 	 	 	“Notwithstanding the above, the minimum vesting period for Other Stock-Based
Awards with no performance-based vesting characteristics shall be three (3)
years (vesting may occur ratably each month, quarter or anniversary of the
grant date over such vesting period), and the minimum vesting period for
Other Stock-Based Awards subject to restrictions based upon the achievement
of specific Performance Goals or performance measures shall be one (1) year;
provided, however, that the Plan Administrator may grant a “de minimis”
number of Other Stock-Based Awards that do not comply with the foregoing
minimum vesting

 

 

	standards. For this purpose “de minimis” means five percent (5%) or less of
the maximum number of shares of Common Stock that may be issued under the
Plan pursuant to Section 5.2(b) herein, subject to adjustment under Section 5.3.”

     IN WITNESS WHEREOF, this amendment has been executed by the undersigned, thereunto duly
authorized, effective as of October 14, 2009.

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

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.

Third Amended and Restated Credit Agreement

27

 

     (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.

Third Amended and Restated Credit Agreement

28

 

The Administrative Agent will make such Loans available to the applicable Borrower by promptly
crediting the Loan amounts so received, in like funds, to such account as designated by such
Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the
reimbursement of an LC Disbursement as provided in Section 2.04(e) shall be remitted by the
Administrative Agent to the applicable Issuing Bank.

     (b) 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:

Third Amended and Restated Credit Agreement

29

 

     (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

Third Amended and Restated Credit Agreement

30

 

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).

Third Amended and Restated Credit Agreement

31

 

     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

Third Amended and Restated Credit Agreement

32

 

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

Third Amended and Restated Credit Agreement

33

 

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, (i) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR
Borrowing.

     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

Third Amended and Restated Credit Agreement

34

 

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

Third Amended and Restated Credit Agreement

35

 

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

Third Amended and Restated Credit Agreement

37

 

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.

     (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.

Third Amended and Restated Credit Agreement

38

 

     (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

Third Amended and Restated Credit Agreement

39

 

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.

The Administrative Agent shall notify the Borrowers and the Lenders of the Effective Date and the
satisfaction (or waiver in accordance with Section 10.02) of the conditions set forth in this
Section 3.01, and such notice shall be conclusive and binding. Notwithstanding the foregoing, the

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 Section 2.04(b).

ARTICLE 4

Representations and Warranties

     The Company, and each Pipeline Company Borrower, in each case with respect to itself and its
Subsidiaries, represents and warrants to the Administrative Agent, the Collateral Agent, each
Issuing Bank and each Lender that:

     Section 4.01. Organization; Powers. The Company is a Business Entity duly formed, validly
existing and in good standing under the laws of the State of Delaware. Each other Credit Related
Party is duly organized or formed, validly existing and, if applicable, in good standing in the
jurisdiction of its organization or formation. Each Credit Related Party possesses all applicable
Business Entity powers and all other authorizations and licenses necessary to engage in its
business and operations as now conducted, the failure to obtain or maintain which would have a
Material Adverse Effect.

     Section 4.02. Authorization. The execution, delivery and performance by each Credit Party of
the Loan Documents to which it is a party are within such Credit Party’s applicable Business Entity
powers, have been duly authorized by all necessary applicable Business Entity action, and do not
contravene (a) any Credit Related Party’s organizational documents, or (b) any law or any material
contractual restriction binding on or affecting any Credit Related Party.

     Section 4.03. Governmental Approvals; No Conflicts. No authorization or approval or other
action by, and no notice to or filing with, any Governmental Authority is required for the due
execution, delivery and performance by any Credit Party of any Loan Document to which it is a
party, except those necessary to comply with laws, rules, regulations and orders required in the
ordinary course to comply with ongoing obligations of such Credit Party under Sections 5.01, 5.02
and 5.07, as applicable.

     Section 4.04. Binding Obligation; Enforceability. This Agreement constitutes, and the other
Loan Documents when delivered hereunder shall constitute, the legal, valid and binding obligations
of each Credit Party that is a party thereto, enforceable against such Credit Party in accordance
with their respective terms, except as may be limited by any applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors’ rights generally or by general
principles of equity.

     Section 4.05. Financial Condition.

     (a) (a) The consolidated balance sheet of the Company and its consolidated Subsidiaries as of
December 31, 2006, and the related consolidated statements of income and cash flows of the Company
and its consolidated Subsidiaries for the fiscal year then ended, reported on by Ernst & Young LLP,
independent public accountants, copies of which have been

Third Amended and Restated Credit Agreement

44

 

furnished to the Administrative Agent and the Lenders prior to the date hereof, present
fairly, in all material respects, the consolidated financial condition of the Company and its
consolidated Subsidiaries as at such date and the consolidated results of the operations of the
Company and its consolidated Subsidiaries for the period ended on such date, all in accordance with
GAAP consistently applied (except as approved by the chief financial officer of such entity and as
disclosed therein), excluding for purposes of this representation the effect of any subsequent
revisions or restatements thereto that may be required by the SEC with respect to (i) the
accounting treatment relating to the negative revision in the proven reserves of crude oil and
natural gas of the Company effected as of or prior to December 31, 2003 by an amount equal to
approximately 1.83 trillion cubic feet equivalent and (ii) the manner in which the Company reported
changes to the accounting for various hedging transactions and related ceiling test impairment
charges.

     (b) The consolidated balance sheets of the Company and its consolidated Subsidiaries as of
September 30, 2007, and the related consolidated statements of income and cash flows of the Company
and its consolidated Subsidiaries for the fiscal period then ended, copies of which have been
furnished to the Administrative Agent on or prior to the date hereof, present fairly, in all
material respects, the consolidated financial condition of the Company and its consolidated
Subsidiaries as at such date and the consolidated results of the operations of the Company and its
consolidated Subsidiaries for the period ended on such date, all in accordance with GAAP
consistently applied (except as approved by the chief financial officer of such entity and as
disclosed therein), subject in the case of such unaudited statements to normal year-end audit
adjustments and reduced footnote disclosure, excluding for purposes of this representation the
effect of any subsequent revisions or restatements thereto that may be required by the SEC with
respect to (i) the accounting treatment relating to the negative revision in the proven reserves of
crude oil and natural gas of the Company effected as of or prior to December 31, 2003 by an amount
equal to approximately 1.83 trillion cubic feet equivalent and (ii) the manner in which the Company
reported changes to the accounting for various hedging transactions and related ceiling test
impairment charges.

     (c) Except as set forth in Schedule 4.05 or in the annual and quarterly reports referred to in
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

Third Amended and Restated Credit Agreement

45

 

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

of creditor from that existing immediately prior to such merger, consolidation or liquidation;
provided, however, that any Pledged Company shall be permitted to merge with another Restricted
Subsidiary, so long as the Equity Interests of the surviving Business Entity are subject to
perfected Transaction Liens and neither the priority of such Liens nor the value of the Collateral
is diminished as a result of such merger;

     (b) any Exempted Guarantor may merge or consolidate with, or liquidate into, any other
Exempted Guarantor or other Business Entity that is not a Credit Related Party, provided that (i)
the surviving Business Entity is, directly or indirectly, a wholly-owned Subsidiary of the Company
and remains a Subsidiary Guarantor, (ii) if the Exempted Guarantor is not the continuing or
surviving Business Entity, the continuing or surviving Business Entity unconditionally assumes by
written agreement satisfactory to the Administrative Agent all of the obligations of such Exempted
Guarantor under the Loan Documents to which the applicable Exempted Guarantor is a party and (iii)
the Lien under the Security Documents in favor of the Collateral Agent on any Collateral owned by
the applicable Exempted Guarantor immediately prior to such merger, consolidation or liquidation
remains effective and perfected immediately

thereafter with no loss of relative priority to any other class of creditor from that existing
immediately prior to such merger, consolidation or liquidation; and

     (c) the Company may merge or consolidate with, or liquidate into, any Business Entity other
than a Credit Related Party, provided that (i) (A) the Company is the continuing or surviving
Business Entity or (B) the continuing or surviving Business Entity is organized under the laws of
the United States or a State thereof and unconditionally assumes by written agreement satisfactory
to the Administrative Agent all of the performance and payment obligations of the Company under any
Loan Documents to which it is a party, and (ii) the Lien under the Security Documents in favor of
the Collateral Agent on any Collateral owned by the Company immediately prior to such merger,
consolidation or liquidation remains effective and perfected immediately thereafter with no loss of
relative priority to any other class of creditor (either contractually, by structural subordination
or otherwise) from that existing immediately prior to such merger, consolidation or liquidation.

     Section 6.06. Use of Proceeds. No Borrower shall use the proceeds of any Loan or any Letter
of Credit for any purpose that would (a) whether directly or indirectly, entail a violation of any
of the Regulations of the Board of Governors, including Regulations T, U and X or (b) constitute a
use other than a general corporate purpose (it being understood that the payments to be made to
Departing Lenders pursuant to Section 3.01(d)(ii) shall constitute a permitted use of proceeds
pursuant to this Section 6.06).

     Section 6.07. Transactions with Affiliates. No Credit Related Party (other than an Exempted
Guarantor) will sell, lease or otherwise transfer any property to, or purchase, lease or otherwise
acquire any property from, or otherwise engage in any other transaction with, any Affiliate of the
Company that is not a Subsidiary of the Company, whether or not in the ordinary course of business,
except (a) transactions on terms no less favorable to such Credit Related Party as would be
obtainable by such Credit Related Party at the time in a comparable arm’s-length transaction or
series of transactions with a person other than an Affiliate of the Company, (b) any Disposition
permitted under Section 6.04 or any merger, consolidation or liquidation permitted under Section
6.05 and (c) transactions the value of which are de minimis in relation to the assets, liabilities
or revenues of the Credit Related Party engaging in such transaction.

     Section 6.08. Restrictive Agreements. No Credit Related Party will, directly or indirectly,
enter into or permit to exist any agreement or other arrangement that prohibits, restricts or
imposes any condition on (a) the ability of any Credit Related Party (other than the Company or the
Exempted Guarantor) to create or permit to exist any Lien on any of its property or (b) the ability
of any Restricted Subsidiary or Pipeline Company Borrower to pay dividends or other distributions
with respect to any shares of its capital stock or to make or repay loans or advances to the
Company or any Subsidiary Guarantor or to Guarantee Debt of the Company or any Subsidiary Guarantor
or to otherwise transfer assets to or invest in the Company or any Subsidiary Guarantor; provided
that (i) the foregoing shall not apply to restrictions and conditions imposed by law or by any Loan
Document, (ii) the foregoing shall not apply to restrictions and conditions existing on the date
hereof and identified on Schedule 6.08, or any extension, refinancing or renewal thereof on market
terms and conditions, (iii) the foregoing shall not apply to customary restrictions and conditions
contained in agreements relating to the sale of a Subsidiary pending such sale, provided that such
restrictions and conditions apply only

Third Amended and Restated Credit Agreement

57

 

to the Subsidiary that is to be sold and such sale is permitted hereunder, (iv) clause (a) of
this Section shall not apply to restrictions or conditions imposed by any agreement relating to
secured Debt permitted by this Agreement if such restrictions or conditions apply only to the
property securing such Debt, (v) clause (a) of this Section shall not apply to customary provisions
in leases and other contracts entered into in the ordinary course of business restricting the
assignment thereof, (vi) the foregoing shall not apply to any Pipeline Company Borrower or its
Subsidiary in connection with the issuance of debt otherwise permitted hereunder on market-clearing

Reference Indenture and (vii) clause (a) and (b) of this Section shall not apply to any assets that
are the subject of an Alternate Program or to any Restricted Subsidiary whose only activities are
to purchase receivables from a Pipeline Company Borrower or a Subsidiary of a Pipeline Company
Borrower and resell such receivables, in each case pursuant to an Alternate Program.

ARTICLE 7

Events of Default

     If any of the following events (“Events of Default”) shall occur and be continuing:

     (a) Any Borrower shall fail to pay any installment of principal of any of its Loans or Notes
when due, or any interest on any of its Loans or Notes or any other amount payable by it hereunder
within five Business Days after the same shall be due; or

     (b) Any representation or warranty made or deemed made by any Credit Party herein or by any
Credit Party (or any of its officers) in connection with this Agreement shall prove to have been
incorrect in any material respect when made or deemed made and, if such representation or warranty
is capable of being cured, such inaccuracy shall remain unremedied for 30 days after written notice
thereof shall have been given to such Credit Party by the Administrative Agent or by any Lender
with a copy to the Administrative Agent; or

     (c) Any Credit Party shall fail to perform or observe any term, covenant, or agreement
applicable to it contained in Section 5.01(a) or 5.08(g) or Article 6; or

     (d) Any Credit Party shall fail to perform or observe any other term, covenant or agreement
contained in the Loan Documents (other than those specified in paragraphs (a) through (c) above) on
its part to be performed or observed and any such failure shall remain unremedied for 30 days after
written notice thereof shall have been given to such Credit Party by the Administrative Agent or by
any Lender with a copy to the Administrative Agent; or

     (e) The Company or any consolidated Subsidiary shall fail to pay any Debt or Guaranty
(excluding Debt and Guarantees incurred pursuant hereto) or Hedging Agreement of such Person in an

interest or premium thereon, when due (whether by scheduled maturity, required prepayment,
acceleration, demand or otherwise) and such failure shall continue after the applicable grace
period, if any, specified in the agreement or instrument relating to such Debt, Guaranty or Hedging
Agreement; or any other default under any agreement or instrument

Third Amended and Restated Credit Agreement

58

 

relating to any such Debt in such aggregate principal amount (excluding Debt and Guarantees
incurred hereunder) or any Secured Hedging Agreement, or any other event (other than an exercise of
voluntary prepayment or voluntary purchase option or analogous right or any issuance or Disposition
of Equity Interests or other assets, or an incurrence or issuance of Debt or other obligations,
giving rise to a repayment or prepayment obligations in respect of such Debt or such Secured
Hedging Agreement), shall occur and shall continue after the applicable grace period, if any,
specified in such agreement or instrument, if the effect of such default or event is to accelerate
the maturity of such Debt in such aggregate principal amount or such Secured Hedging Agreement; or

     (f) • Any Borrower, any Guarantor or any other Credit Related Party (other than any Borrower
or Guarantor) having total Assets in excess of $100,000,000 (any of the foregoing, a “Material
Credit Related Party”) shall generally not pay its debts as such debts become due; or admit in
writing its inability to pay its debts generally; or make a general assignment for the benefit of
creditors; or any proceeding shall be instituted or consented to by any Material Credit Related
Party seeking to adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up,
reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts
under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking
the entry of an order for relief or the appointment of a receiver, trustee, or other similar
official for it or for any substantial part of its property; or any such proceeding shall have
been instituted against any Material Credit Related Party and either such proceeding shall not be
stayed or dismissed for 60 consecutive days or any of the actions referred to above sought in such
proceeding (including the entry of an order for relief against it or the appointment of a receiver,
trustee, custodian or other similar official for it or any substantial part of its property) shall
occur; or any Material Credit Related Party shall take any corporate action to authorize any of
the actions set forth above in this paragraph (f); or

     (g) Any final judgment or order for the payment of money in an aggregate amount in excess of
$100,000,000 (net of insurance coverage which is reasonably expected to be paid by the insurer)
shall be rendered against the Company, any Credit Related Party or any combination thereof and the
same shall remain undischarged for a period of 60 consecutive days during which execution (other
than any enforcement proceedings consisting of the mere obtaining and filing of a judgment lien or
obtaining of a garnishment or similar order so long as no foreclosure, levy or similar process in
respect of such judgment lien, or payment over in respect of such garnishment or similar order, has
commenced and is continuing or has been completed (collectively, the “Permitted Execution
Actions”)) shall not be effectively stayed, or any action, other than a Permitted Execution Action,
shall be legally taken by a judgment creditor to attach or levy upon any property or assets of the
Company or any other Credit Related Party to enforce any such judgment or order; provided, however,
that with respect to any such judgment or order that is subject to the terms of one or more
settlement agreements that provide for the obligations thereunder to be paid or performed over
time, such judgment or order shall not be deemed hereunder to be undischarged unless and until the
Company or any other Credit Related Party shall have failed to pay any amounts due and owing
thereunder (payment of which shall not have been stayed) for a period of 30 consecutive days after
the respective final due dates for the payment of such amounts; or

59

 

     (h) Any Termination Event with respect to a Plan shall have occurred and, 30 days after notice
thereof shall have been given to the Company by the Administrative Agent, such Termination Event
shall still exist; or the Company or any ERISA Affiliate shall have been notified by the sponsor
of a Multiemployer Plan that it has incurred Withdrawal Liability to such Multiemployer Plan; or
the Company or any ERISA Affiliate shall have been notified by the sponsor of a Multiemployer Plan
that such Multiemployer Plan is in reorganization, or is insolvent or is being terminated, within
the meaning of Title IV of ERISA; or any Person shall engage in a “prohibited transaction” (as
defined in Section 406 of ERISA or Section 4975 of the Code) involving any Plan; and in each case
in clauses (i) through (iv) above, such event or condition, together with all other such events or
conditions, if any, would result in an aggregate liability of the Company or any ERISA Affiliate
that would have a Material Adverse Effect; or

     (i) At any time (i) any “person” (within the meaning of Section 13(d) of the Securities
Exchange Act of 1934) other than the Company or a Subsidiary of the Company or any employee benefit
plan maintained for employees of the Company and/or any of its Subsidiaries or the trustee
therefor, shall have acquired direct or indirect ownership of and paid for in excess of 50% of the
outstanding capital stock of the Company entitled to vote in elections for directors of the Company
or (ii) more than half of members of the Board of Directors of the Company consists of individuals
who (1) were not members of the Board of Directors of the Company at the Effective Date and (2)
were not appointed, elected or nominated by the Board of Directors of the Company at a time when no
Event of Default existed under this clause (ii); or

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

     (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.

ARTICLE 8

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

Third Amended and Restated Credit Agreement

61

 

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

Third Amended and Restated Credit Agreement

62

 

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.

Third Amended and Restated Credit Agreement

ARTICLE 9

The Agents

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

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

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

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

Third Amended and Restated Credit Agreement

64

 

other experts selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

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

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

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

     (ix) if to any other Lender in its capacity as an Issuing Bank, to it at the address
provided to the Company for notices to such Issuing Bank in such capacity; and

     (x) if to any other Lender, to it at its address (or telecopy number) set forth in its
Administrative Questionnaire.

     (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 communications.

     (c) Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and 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 mail or courier on the date of delivery
thereof to the address specified herein for such notice, or if by telecopier when the answerback is
received or if by other means, on the date of receipt; provided that a notice given by telecopier
or electronic communication in accordance with this Section 10.01 but received on any day other
than a Business Day or after business hours in the place of receipt, will be deemed to be received
on the next Business Day in that 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:

Third Amended and Restated Credit Agreement

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

Third Amended and Restated Credit Agreement

68

 

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

Third Amended and Restated Credit Agreement

69

 

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

70

 

     (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

Third Amended and Restated Credit Agreement

71

 

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

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

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

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

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

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

Third Amended and Restated Credit Agreement

72

 

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

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

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

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

Third Amended and Restated Credit Agreement

73

 

     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

Third Amended and Restated Credit Agreement

74

 

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

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

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.

interest is granted by such Released Party pursuant to the Security Documents shall be released

Third Amended and Restated Credit Agreement

Schedule 3 — Page 1

 

     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.

	 	New York, New York
	 
	 	                    , 200_

     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.

     (e) This Agreement constitutes, and the other Security Documents when delivered shall
constitute, the legal, valid and binding obligations of each Credit Party that is a party thereto,
enforceable against such Credit Party in accordance with their respective terms, except as may be
limited by any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting creditors’ rights generally or by general principles of equity.

     (f) With respect to any Credit Party that is a Grantor, all Collateral pledged by such Credit
Party hereunder consisting of certificated securities has been delivered to the Collateral Agent.

     (g) With respect to any Credit Party that is a Grantor, this Agreement is effective to create
in favor of the Collateral Agent, for the ratable benefit of the Secured Parties, a Lien on, and
security interest in, all right, title and interest of such Grantor in the Collateral pledged by
such Credit Party hereunder 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 Transaction Lien that can be perfected by the filing of such financing statements. All
actions required by Section 5.03 to provide control to the Collateral Agent with respect to
Collateral pledged by such Credit Party hereunder for which control can be established have been
taken, including delivery of such Collateral consisting of certificated securities to the
Collateral Agent, duly endorsed for transfer or accompanied by duly executed instruments of
transfer.

     (h) With respect to any Credit Party that is a Grantor, the Pledged Equity pledged as
Collateral by such Credit Party to the Collateral Agent hereunder has (to the extent applicable)
been duly authorized and validly issued and is (to the extent applicable) fully paid and
non-assessable. With respect to any Equity Interests pledged by such Credit Party to the
Collateral Agent hereunder that are uncertificated securities, such Credit Party has caused the
issuer thereof to agree in an authenticated record with such Credit Party and the Collateral Agent
that such issuer will comply with instructions with respect to such uncertificated securities
originated by the Collateral Agent without further consent of such Credit Party and has delivered a
copy of such authenticated

9

 

record to the Collateral Agent. If such Credit Party is a Pledged Company, such Credit Party
confirms that it has received notice of such security interest.

     (i) With respect to any 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.

All representations 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 deemed the
schedules to this Agreement. Each Credit Party will not change its 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.

ARTICLE 4

Pledged Accounts

     Section 4.01. Creation of Pledged Accounts. (a) The Collateral Agent is hereby directed by
the Company and each Grantor to cause to be established on or before the date hereof with, and
maintained thereafter by, the Depository Bank at its offices in New York City, New York (ABA No.
021000021), in the name of the Collateral Agent as entitlement holder and under the sole control
and dominion of the Collateral Agent and subject to the terms of this Agreement, the following
segregated securities accounts (collectively, the “Pledged Accounts”):

     (i) a master collateral account, Account No. 10205184 (the “Collateral Account”),
into which Mandatory Asset Reduction Amounts will be deposited and to which Unused Cash
Collateral and certain amounts described in Section 4.03(f) will be transferred;

10

 

     (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

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.

11

 

     (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

12

 

Lenders, apply funds in the Cash Collateral Account in accordance with Section 6.02.

     (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 Error! Reference source not found. 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

13

 

Investments Account, for each such Restricted Subsidiary or each such Covered Asset.

     (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 Error! Reference source not found. 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

14

 

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.

15

 

     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 Error!
Reference source not found. 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

16

 

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

17

 

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

18

 

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 Collateral from time to time carried in the
Pledged Accounts, (B) the sole entitlement holder against the Depository Bank with respect to each
of the Pledged Accounts, (C) the sole Person having dominion and control over each of the Pledged
Accounts and any and all assets, property and items from time to time carried in such Pledged
Accounts (including cash) and (D) the sole Person entitled to exercise the rights with respect to
the Pledged Accounts; and (ii) has credited and will continue to credit such assets, property and
items to the Pledged Accounts in accordance with written instructions given pursuant to, and the
other terms and conditions of, this Agreement.

or credited to the Pledged Accounts, shall constitute financial assets, and the Depository Bank
shall treat all such property as financial assets under Article 8 of the UCC.

     (e) Notwithstanding any other provision in this Agreement to the contrary, the Depository Bank
(i) shall comply with any and all entitlement orders and other directions originated by, and only
by, the Collateral Agent in respect of the Pledged Accounts and the Account Collateral from time to
time carried therein without any further consent or action by the Company or any other Person and
(ii) shall not comply with the entitlement orders of any other Person.

     (f) The “securities intermediary’s jurisdiction” (within the meaning of Section 8-110(e) of

this Agreement with respect to the Account Collateral carried in the Pledged Accounts must be given
to the Depository Bank, and only pursuant to and subject to the terms and conditions of this
Agreement.

19

 

     (h) Anything herein to the contrary notwithstanding, the Depository Bank will not be required
to follow any instruction that would violate any Applicable Law, decree, regulation or order of any
Governmental Authority (including any court or tribunal) or the terms of this Agreement.

     (i) The Depository Bank has not entered into and will not enter into any agreement with any
other Person relating to the Pledged Accounts or any Pledged Financial Assets credited thereto

The Depository Bank has not entered into any other agreement with the Company or any other Person
purporting to limit or condition the duties of the Depository Bank to comply with entitlement
orders originated by the Collateral Agent as set forth in Section 4.08(e).

     (j) The Depository Bank hereby permanently waives and releases any Lien, right of setoff or
other right it may have against the Pledged Accounts and any Pledged Financial Assets or Pledged
Security Entitlements carried in or credited to the Pledged Accounts and any credit balance or cash
in the Pledged Accounts, and agrees that it will not assert any such Lien or other right in, to or
against the Pledged Accounts or any Pledged Financial Asset or Pledged Security Entitlement carried
therein or credited thereto, or any credit balance or cash in the Pledged Accounts.

     (k) The Depository Bank will send copies of all statements and confirmations for and in
respect of the Pledged Accounts simultaneously to the Company and the Collateral Agent.

     (l) All securities or other property underlying any financial assets consisting of Account

Depository Bank, endorsed to the Depository Bank or in blank or credited to another securities
account or securities accounts maintained in the name of the Depository Bank, and in no case will
any financial asset consisting of Account Collateral deposited in or credited to a Pledged Account
be registered in the name of the Company, payable to the order of the Company or specially endorsed

the Depository Bank or in blank.

     (m) If any Person (other than the Collateral Agent) asserts to the Depository Bank any Lien,
encumbrance or adverse claim (including any writ, garnishment, judgment, warrant of attachment,
execution or similar process) against any Account Collateral, the Depository Bank will as promptly
as practicable thereafter notify the Company and the Collateral Agent thereof.

20

 

     Section 4.09. Force Majeure. Neither the Collateral Agent nor the Depository Bank shall
incur any liability for not performing any act or fulfilling any obligation hereunder by reason of

would be owed by such Grantor but

24

 

for the fact they are unenforceable or not allowable due to the existence of an Insolvency
Proceeding involving such Grantor.

     Section 5.03. Delivery And Control of Collateral. (a) All certificates or instruments

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 satisfactory to, and to be delivered to, the Collateral Agent. With respect to any

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

require from time to time in order to (i) carry out more effectively the purposes of the Security

25

(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

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

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.

     (b) Each Grantor hereby authorizes the Collateral Agent to file one or more financing or
continuation statements, and amendments thereto, including one or more financing statements
indicating that such financing statements cover all right, title and interest of such Grantor in
and to the Collateral, in each case without the signature of such Grantor. The Collateral Agent
shall provide a copy of each such financing statement to each Grantor. A photocopy or other
reproduction of this Agreement or any financing statement covering the Collateral or any part
thereof shall be sufficient as a financing statement where permitted by law. Each Grantor ratifies
its authorization for the Collateral Agent to have filed such financing statements, continuation
statements or amendments filed prior to the date hereof.

     Section 5.05. Grantors Remain Liable. Anything herein to the contrary notwithstanding, (a)
each Grantor shall remain liable under any contracts and agreements included in such Grantor’s
Collateral (including, with respect to Security Collateral, any obligations under limited liability
company agreements, limited partnership agreements and any other organizational or constituent

26

 

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

(i) it will cause each Pledged Company the Pledged Equity in which has been pledged by such Grantor
hereunder, not to issue any Equity Interests or other securities in addition to or in substitution
for the Pledged Equity issued by such Pledged Company, except to such Grantor, (ii) it will pledge
hereunder, immediately upon such Grantor’s acquisition (directly or indirectly) thereof, any and
all additional Equity Interests issued by such Pledged Company, and (iii) it will cause all such
Equity Interests issued by such Pledged Company to be certificated securities under Article 8 of
the UCC and under Article 8 or Chapter 8 of the Uniform Commercial Code as in effect in the
jurisdiction of organization of such Pledged Company; provided, however, that this Section 5.06
shall not limit any Grantor’s rights under Section 5.07(a)(ii).

     (b) Ownership of Equity Interests in Grantors. The Company agrees and covenants that it will
at all times own, directly or indirectly, 100% of the outstanding Equity Interests (including all
voting, economic and other rights associated therewith) in each Grantor, except for the rights of
the Collateral Agent hereunder with respect to the Equity Interests in any Grantor that is a
Pledged Company.

     (c) Ownership of Equity Interests in Pledged Companies. Each Grantor (including any successor
thereto pursuant to a merger or consolidation permitted under Section 6.05 of the Credit Agreement)
agrees and covenants that (i) it will at all times remain a registered organization, as defined in

Credit Agreement and except for the rights of the Collateral Agent hereunder.

Account (and not deposited into, or transferred to, another Pledged Account) to (A) the
Administrative Agent, the Collateral Agent or the Depository Bank in respect of amounts
due and payable hereunder to such Persons or other Secured Parties, (B) any Secured Party
or (C) the Company or any Restricted Subsidiary (or any other Person designated in writing
by the Company to the Collateral Agent to receive such payment), in each case in
accordance with the Security Documents, the Transaction Liens on such amount shall be
automatically released without further action or consent by the Collateral Agent or any
other Person (including any Secured Party).

     (ii) Release of Lien on Collateral. Upon the Disposition of any Collateral in a
transaction permitted under the Credit Agreement and the other Loan Documents, the
Transaction Liens on such Collateral shall be automatically released without further
action or consent by the Collateral Agent or any other Person (including any other Secured
Party).

     (b) Full Release of Collateral. On the earlier of (A) the Final Payment Date or (B) the date
on which the requisite percentage of the Lenders have approved the release of the Transaction Liens
in accordance with Section 10.02 of the Credit Agreement, the Transaction Liens shall be fully and

     (i) each Grantor shall be entitled to exercise any and all voting and other

conversion or exchange thereof) of such Grantor or any part thereof at any time and for
any purpose; provided that such Grantor will not exercise or refrain from exercising any
such right if such action would violate this Agreement;

28

 

     (ii) except as provided in Section 5.08(c), each Grantor shall be entitled to receive
and retain any and 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

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)) 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

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

     (d) Upon the occurrence and during the continuance of any Event of Default:

     (i) all rights of each Grantor to exercise or refrain from exercising the voting and
other consensual rights that it would otherwise be entitled to exercise pursuant to
Section 5.08(a)(i) shall, upon delivery by the Collateral Agent to such Grantor of a
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 of such Event of Default, cease, and all such rights shall thereupon become
vested in the Collateral Agent, and any and all such cash dividends, interest and other
cash distributions received by such Grantor shall be promptly 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 accordance with Section 4.02(b)(iii). With
respect to any issuer of 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

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, shall be segregated

Collateral Agent who shall cause the Depository Bank to deposit same in a subaccount of
the Cash Collateral Account to be administered as above provided in this Section
5.08(d)(ii); and

it would otherwise be 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, shall be
segregated from the other funds of such Grantor and shall be promptly 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 administered in accordance with this
Section 5.08(d)(iii).

     Section 5.09. The Collateral Agent Appointed Attorney-in-fact. Each Grantor hereby
irrevocably appoints the Collateral Agent such Grantor’s attorney-in-fact, with full authority in
the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to
time, in the Collateral Agent’s discretion, to take any action and to execute any instrument that
the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement
and any other Security Document with respect to the Collateral and the Collateral Agent’s rights
and remedies with respect thereto, including:

enforce the rights of the Collateral Agent and any other Secured Party with respect to any of the
Collateral;

31

 

provided that the Collateral Agent shall not exercise the power and authority granted to it
pursuant to this Section 5.09 except during such period as an Event of Default has occurred and is
continuing.

     Section 5.10. Netting of Accounts. Notwithstanding any other provision of this Agreement or
the Credit Agreement, so long as no Event of Default has occurred 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 or any Subsidiaries of such
other Credit Related Party.

Disposed of, and for that purpose the Collateral Agent may execute all necessary
deeds, bills of sale and instruments of assignment and transfer, and may
substitute one or more Persons with like power.

     (iii) Collateral Agent May File Proofs of Claim. In case of the pendency of any
Insolvency Proceeding relative to the Company or any of its Subsidiaries or the
Collateral, the Collateral Agent (irrespective of whether any of the outstanding Secured
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 in order to protect the
rights of the Secured Parties under the Security Documents and with respect to the
Collateral, and to file such other papers or documents as may be necessary or advisable in
order to have the claims of the Collateral Agent (including any claim for the reasonable
compensation, disbursements and advances of the Collateral Agent in its

33

 

individual or trust capacity and its agents and counsel) and of any other Secured
Parties in respect of the Security Documents and the Collateral allowed in such judicial
proceeding and (B) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Secured Party to make payments with respect to
such claims to the Collateral Agent.

     (iv) Collateral Agent May Enforce Claims. All rights of action and claims under this
Agreement and the other Security Documents may be prosecuted and enforced by the
Collateral Agent; provided that the Collateral Agent is also hereby appointed as agent for
the other Secured Parties for the purposes of protecting their interests in and to any
portion of the Collateral and under the Security Documents, and the Collateral Agent shall
take such action solely as agent for the Secured Parties.

     Section 6.02. Application of Proceeds. If an Event of Default shall have occurred and be
continuing and the Collateral Agent applies (i) any cash held in the Pledged 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 Obligations in the following order of priorities:

     first, to pay the expenses of such Disposition, including reasonable compensation to
agents of and counsel for the Collateral Agent, and all expenses, liabilities and advances
incurred or made by the Collateral Agent in connection with the Security Documents, and
any other amounts then due and payable to the Collateral Agent in its capacity as such
pursuant to Section 9.01 hereof or Section 10.03 of the Credit Agreement;

     second, to pay the unpaid principal of all Borrowings and all unreimbursed LC
Disbursements and to Cash Collateralize all outstanding Letters of Credit, all ratably
until the principal of all Borrowings and all unreimbursed LC Disbursements shall have
been paid in 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;

     fourth, to pay all other Secured Obligations ratably, until payment in full of all
such other Secured Obligations shall have been made; and

34

 

     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.

duplication), defend and save and hold harmless each of the Collateral Agent, the Depository Bank

and all claims, damages, 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 (i) this Agreement or the other Security Documents, or
(ii) as a result of the execution or delivery of this Agreement or 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 constitute a guaranty of
payment of any principal, interest, facility or commitment fees, rental or other lease payments, or
analogous amounts, under any Secured Obligations; provided that nothing in this Section 9.01(a)
shall limit the liability of any Credit Party for the payment of any Secured Obligation, to the
extent such liability arises under any other Financing Document, including any liability arising
under this Agreement.

     (b) Each Credit Party will pay to the Collateral Agent the amount of any and all reasonable
out-of-pocket expenses, including the reasonable fees and 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 and the other Security 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

the expiration, cancellation, termination or modification of this Agreement or the other Security
Documents, the resignation or removal of

36

 

the Collateral Agent, Depository Bank or Secured Parties and the provision of any subsequent
or additional indemnity by any Person.

     (d) All amounts due under this Section 9.01 shall be payable not later than 30 days after the
delivery of written demand to the Company therefor.

     Section 9.02. Amendments; Waivers, Etc. No amendment, modification or waiver of any
provision of this Agreement or any other Security Document, and no consent with respect to any
departure by the Collateral Agent, any other Secured Party or any Credit Party herefrom or
therefrom, shall be effective unless the same shall be in writing and signed by the Credit Parties
and the Collateral Agent in accordance with the Credit Agreement. Any such waiver or consent shall
be effective only in the specific instance and for the specific purpose for which given.

     Section 9.03. Security Interest Absolute And Waivers. (a) The obligations of each Credit
Party under or in respect of this Agreement or any other Security Document to which such Credit
Party is a party are independent of the Secured Obligations or any 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 Collateral Agent against each Credit Party to enforce this
Agreement or any 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) any defenses to its
obligations under the Security Documents that it may now have or may hereafter acquire, which
defenses in any way relate to, any or all of the following:

     (i) any lack of validity or enforceability of any Financing Document or any other
agreement or instrument relating thereto;

     (ii) any change in the time, manner or place of payment of, or in any other term of,
all or any of the Secured Obligations or any other obligations of any Credit Party under
or in respect of the Financing Documents or any other amendment or waiver of or any
consent to any departure from any Financing Document, including any increase in the
Secured Obligations resulting from the extension of additional credit to any Credit Party
or any of its Subsidiaries or otherwise;

     (iii) any Condemnation, exchange, release or non-perfection of any Collateral or any
other collateral, or any release, amendment or waiver

37

 

of, or consent to, or departure from any Guaranty of all or any of the Secured
Obligations;

     (iv) any manner of application of any Collateral or any other collateral, or proceeds
thereof, to all or any of the Secured Obligations, or any manner of sale or other
disposition of any Collateral or any other collateral for all or any of the Secured
Obligations or any other obligations of any Credit Party under or in respect of the
Financing Documents or any other assets of any Credit Party or any of its Subsidiaries;

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

     (vi) any failure of any Secured Party to disclose to any Credit Party any information
relating to the business, condition (financial or otherwise), operations, performance,
assets, nature of assets, liabilities or prospects of any other Credit Party now or
hereafter known to such Secured Party (each Credit Party waiving any duty on the part of
the Secured Parties to disclose such information);

     (vii) the failure of any other Person to execute or deliver this Agreement or any
other Security Document, guaranty or agreement or the release or reduction of liability of
any Credit Party or other grantor or surety with respect to the Secured Obligations; or

     (viii) any other circumstance (including any statute of limitations) or any existence
of or reliance on any representation by any Secured Party that might otherwise constitute
a defense available to, or a discharge of, such Credit Party or any other Credit Party or
third party grantor of a secured interest, but specifically excluding any defense or
discharge arising as a result of performance or indefeasible payment.

     (b) This Agreement shall continue to be effective or be reinstated, as the case may be, if at
any time any payment of any of the Secured Obligations is rescinded or must otherwise be returned
by any Secured Party or by any other Person upon the insolvency, bankruptcy or reorganization of
any Credit Party or otherwise, all as though such payment had not been made.

     (c) Each Credit Party hereby unconditionally and irrevocably waives promptness, diligence,
notice of acceptance, presentment, demand for performance, notice of nonperformance, default,
notice of intent to accelerate, acceleration, protest or dishonor and any other notice with respect
to any of the Secured Obligations and this Agreement or any other Security Document to which such
Credit Party is a party and any requirement that any Secured Party protect, secure, perfect or
insure any Lien or any property subject thereto or

38

 

exhaust any right or take any action against any Credit Party or any other Person or any
Collateral.

     (d) Each Credit Party hereby unconditionally and irrevocably waives any right to revoke this
Agreement or any other Security Document to which such Credit Party is a party and acknowledges
that this Agreement or any other Security Document to which such Credit Party is a party is
continuing in nature and applies to all Secured Obligations, whether existing now or in the future.

     (e) Each Credit Party hereby unconditionally and irrevocably waives (i) any defense arising by
reason of any claim or defense based upon an election of remedies by the Collateral Agent that in
any manner impairs, reduces, releases or otherwise adversely affects the subrogation,
reimbursement, exoneration, contribution or indemnification rights of such Credit Party or other
rights of such Credit Party to proceed against any other Credit Party, any other guarantor or any
other Person or any Collateral and (ii) any defense based on any right of set-off or counterclaim
against or in respect of the obligations of such Credit Party hereunder.

     (f) Each Credit Party and each of the Secured Parties confirms that it is the intention of all
such Persons that this Agreement, the other Security Documents and the obligations of each Credit
Party hereunder or thereunder do not constitute a fraudulent transfer or fraudulent conveyance for
purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar foreign, federal or state law to the extent applicable to this
Agreement, any other Security Document and the obligations of each Credit Party hereunder or
thereunder or in connection with any Insolvency Proceeding in respect of any Credit Party. To
effectuate the foregoing intention, the Collateral Agent, the other Secured Parties and the
Subsidiary Grantors hereby irrevocably agree that the obligations of each Subsidiary Grantor under
this Agreement and the other Security Documents at any time shall not exceed the maximum amount as
will result in the obligations of such Subsidiary Grantor under this Agreement and the other
Security Documents not constituting a fraudulent transfer or fraudulent conveyance (after giving
effect to Section 2.02 of the Subsidiary Guarantee Agreement).

     (g) Each Credit Party acknowledges that it will receive substantial direct and indirect
benefits from the financing arrangements contemplated by the Security Documents and that the
waivers set forth in this Section 9.03 are knowingly made in contemplation of such benefits.

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,

6

 

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.

     Section 11.06. Reinstatement. The guarantee contained in this Article 2 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 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 Subsidiary Guarantor or any
substantial part of its property, or otherwise, all as though such payments had not been made.

     Section 11.07. Payments. Each Subsidiary Guarantor hereby agrees that payments required to
be made by it hereunder will be paid to the Collateral Agent without set-off or counterclaim in
dollars at the office of the Collateral Agent identified in Section 9.04 of the Security Agreement.

any Subsidiary Guarantor hereunder shall be effected in the manner provided for in Section 9.04 of

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.

     Section 12.04. Enforcement Expenses; Indemnification.

claims, damages, 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

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

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

     Section 12.05. Successors And Assigns. This Agreement shall be binding upon the successors
and assigns of each Subsidiary Guarantor and shall inure to the benefit of the Collateral Agent and
its successors and assigns for the ratable benefit of the Secured Parties and their successors and
assigns; provided that, except in 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 12.06. 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

9

 

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.

     Section 12.07. Counterparts. This Agreement may be executed in any number of counterparts,
each of which when so executed shall be deemed to be an original and all of which taken together
shall constitute one and the same agreement. Delivery of an executed counterpart of a signature
page to this Agreement by telecopier shall be effective as delivery of an original executed
counterpart of this Agreement.

     Section 12.08. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

     Section 12.09. Section Headings. The Section headings used in this Agreement are for
convenience of reference only and are not to affect the construction hereof or be taken into
consideration in the interpretation hereof.

     Section 12.10. Integration. This Agreement and the other Loan Documents to which each
Subsidiary Guarantor is a party represent the agreement of such Subsidiary Guarantor, the
Collateral Agent and the Secured Parties with respect to the subject matter hereof and thereof, and
there are no promises, undertakings, representations or warranties by the Collateral Agent or any

10

 

Secured Party relative to the subject matter hereof and thereof not expressly set forth or
referred to herein or in such other Loan Documents.

     Section 12.11. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     Section 12.12. Submission to Jurisdiction; Waivers. Each Subsidiary Guarantor hereby
irrevocably and unconditionally:

     (a) submits for itself and its property in any legal action or proceeding by the Collateral
Agent against it relating to this Agreement and the other Loan Documents to which it 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 thereof;

     (b) consents that any such action or proceeding may be brought in such courts and waives any
objection that it may now or hereafter have to the venue of any such action or proceeding in any
such court or that such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same;

     (c) agrees that service of process in any such action or proceeding may be effected by mailing
a copy thereof by registered or certified mail (or any substantially similar form of mail), postage
prepaid, to such Subsidiary Guarantor at its address referred to 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 12.13. Acknowledgements. Each Subsidiary Guarantor hereby acknowledges that:

     (a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement and the other Loan Documents to which it is a party;

     (b) neither the Collateral Agent nor any Secured Party has any fiduciary relationship with or
duty to such Subsidiary Guarantor arising out of or in connection with this Agreement or any of the
other Loan Documents, and the relationship between the Subsidiary Guarantors, on the one hand, and
the

11

 

Collateral Agent and the Secured Parties, on the other hand, in connection herewith or
therewith is solely that of debtor and creditor; and

     (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by
virtue of the transactions contemplated hereby among the Secured Parties or among the Subsidiary
Guarantors and the Secured Parties.

     Section 12.14. Releases. (a) 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.

     Section 12.15. WAIVER OF JURY TRIAL. EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY AND FOR ANY COUNTERCLAIM THEREIN.

     Section 12.16. Sole Right of 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).

EXHIBIT F-1

FORM OF

OPINION OF BRACEWELL & GIULIANI LLP, SPECIAL NEW YORK COUNSEL TO

THE COMPANY

November ___, 2007

To the Administrative Agent and the Collateral Agent under the

Credit Agreement described below and to each Lender party to

such Credit Agreement

     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 Parties”), in connection with the Third Amended and Restated Credit
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 below, any federal or state
securities, commodities, insurance, or investment company laws and regulations; (ii) any federal or
state labor, pension, or other employee benefit laws and regulations; (iii) any federal or state
antitrust, trade or unfair competition laws and regulations; (iv) any federal or state laws 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 state laws or regulations relating to copyrights, patents,
trademarks, or other intellectual property.

 

 

To the Administrative Agent and the Collateral Agent under the Credit Agreement

described below and to each Lender party to such Credit Agreement

November ___, 2007

Page 2

     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”).

To the Administrative Agent and the Collateral Agent under the Credit Agreement

described below and to each Lender party to such Credit Agreement

November ___, 2007

Page 3

     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.

To the Administrative Agent and the Collateral Agent under the Credit Agreement

described below and to each Lender party to such Credit Agreement

November ___, 2007

Page 4

     (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

 

To the Administrative Agent and the Collateral Agent under the Credit Agreement

described below and to each Lender party to such Credit Agreement

November ___, 2007

Page 5

     (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

5

 

To the Administrative Agent and the Collateral Agent under the Credit Agreement

described below and to each Lender party to such Credit Agreement

November ___, 2007

Page 6

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.

     (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

6

 

To the Administrative Agent and the Collateral Agent under the Credit Agreement

described below and to each Lender party to such Credit Agreement

November ___, 2007

Page 7

paragraphs 6-9 hereof, or (iv) whether the properties described in the Security Agreement are
the properties and interests intended to be encumbered thereby.

     (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

     (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.

Lender party to such Credit Agreement

     Re: Credit Agreement dated as of November ___, 2007

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”);

Exhibit F-2 – Page 1

 

	 	(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

Third Amended and Restated Credit Agreement

Exhibit F-2 – Page 2

 

	 	 	 	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.

	 	(2)	 	The execution, delivery, and performance by each Opinion Party of each Opinion
Document to which it is a party:

	 	(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;
	 
	 	(b)	 	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;
	 
	 	(c)	 	do not and will not contravene any U.S. federal law or
regulation applicable to the Opinion Parties (excluding provisions of U.S.
federal law expressly 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 Company Act
applicable to the Opinion Parties.

	 	(3)	 	Each Opinion Document has been duly executed and delivered by each Opinion
Party to it.
	 
	 	(4)	 	No authorization or approval or other action by, and no notice to or filing
with, any U.S. federal governmental authority or regulatory body (including, without
limitation, the Federal Energy Regulatory Commission), 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 performance by each Opinion Party of any Opinion Document to
which it is a party, except for:

	 	(a)	 	authorizations, approvals and other actions that have been
obtained or taken and notices and filings that have been made, in each case
that are in full force and effect; and
	 
	 	(b)	 	authorizations, approvals, other actions, notices and filings
required in the ordinary course of business in connection with the performance
by each Opinion Party of its obligations under certain covenants and warranties
contained in the Opinion Documents to which it is a party and pursuant to
securities and other laws that may be applicable to the disposition of any
collateral subject thereto.

	 	(5)	 	To the best of my knowledge, there is no action, suit or proceeding pending or
overtly threatened against or involving the Opinion Parties (a) that, in my

Third Amended and Restated Credit Agreement

Exhibit F-2 – Page 3

 

	 	 	 	judgment (taking into account the exhaustion of all appeals), would have a Material
Adverse Effect (provided that this opinion does not address any actions, suits, or
proceedings that have been disclosed in the annual report on Form 10-K for the
fiscal year ended December 31, 2006, or the quarterly report on Form 10-Q for the
quarter ended June 30, 2007, filed by the Borrowers with the Securities and Exchange
Commission or (b) that purports to affect the legality, validity, binding effect or
enforceability of the Opinion Documents.
	 
	 	(6)	 	The Initial Pledged Equity identified on Schedule II to the Security Agreement
has (to the extent applicable) been duly authorized and validly issued and is fully
paid and non-assessable.

     The opinions expressed herein are given as of the date hereof. The opinions expressed herein
are limited solely to those expressly set forth herein, and I express no opinions by implication.
The opinions expressed herein are solely for the benefit of the addressees hereof and any other
person or entity becoming an Administrative Agent, a Collateral Agent or Lender under the Credit
Agreement in accordance therewith, and any participant of any Lender in accordance with the Credit
Agreement, in each case above, in connection with the transactions 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 without my prior written consent.

Very truly yours,

EXHIBIT G

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

Third Amended and Restated Credit Agreement

Exhibit G – Page 1

 

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.

     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.

Third Amended and Restated Credit Agreement

Exhibit G

 

     Lender hereby waives any and all notice in respect of the Senior Debt, present or future, and
agrees and consents that without notice to or assent by any holder or holders of the Subordinated
Debt:

     (i) the obligation and liabilities of the Borrower or any other party or parties for or upon

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;

     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 in the subordination provisions of this Note is intended to or shall impair,
as between the Borrower, its creditors other than the holders of the Senior Debt, and Lender, the
obligation of the Borrower, which is absolute and unconditional, to pay to Lender the principal of,
premium, if any, and interest on this Note, as and when the same shall become due and payable
(except as otherwise provided in this Note) in accordance with its terms, or is intended to or
shall affect the relative rights of Lender and other creditors of the Borrower other than the
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

Third Amended and Restated Credit Agreement

Exhibit G

 

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.

     The subordination provisions hereof shall be binding upon any holder of Subordinated Debt and
