Any determination that a Lender is a Defaulting Lender under clauses (a) through (d) above will be made by the Administrative Agent in its sole discretion acting in good faith, provided that the determination that the Administrative Agent is a Defaulting Lender under clauses (a) through (d) above may be made by any Issuing Bank with a Letter of Credit Commitment in excess of $100,000,000 at the time of such determination in its sole discretion acting in good faith. The Administrative Agent (or applicable Issuing Bank) will promptly send to all parties hereto a copy of any notice to WPZ provided for in this definition. For avoidance of doubt (A) an assignee of a Defaulting Lender shall not be deemed to be a Defaulting Lender solely by virtue of the fact that it is an assignee of a Defaulting Lender and (B) when a Defaulting Lender ceases to be a Defaulting Lender (due to assignment to a new Lender, commitment reduction pursuant to Section 2.09(d), clause (ii) of the proviso of this definition of Defaulting Lender, or otherwise), all Cash Collateral in connection with such Defaulting Lender with respect to Letters of Credit

THE CREDITS

Section 2.01 Commitments.

(a) Loans. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to each Borrower from time to time during the Availability Period in an aggregate principal amount that will not result in (i) such Lender’s Credit Exposure exceeding such Lender’s Commitment or (ii) the sum of the total Credit Exposures exceeding the Aggregate Commitments; provided, however, that in no event shall the sum of the total Credit Exposures with respect to each of NWP and TGPL, individually, exceed $500,000,000 (the “Borrower Sublimit”), it being understood that the termination of a Borrower Sublimit for either NWP or TGPL shall not result in a reduction of the Aggregate Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, each Borrower may borrow, prepay and reborrow Loans.

(b) [Reserved].

(i) WPZ shall have the option, without the consent of the Lenders, from time to time to cause one or more increases in the Aggregate Commitments by adding, subject to the prior approval of the Administrative Agent and the Issuing Banks (such approval not to be unreasonably withheld), to this Agreement one or more financial institutions as Lenders (collectively, the “New Lenders”) or by allowing one or more Lenders to increase their respective Commitments; provided however that: (A) prior to and after giving effect to the increase, no Default or Event of Default shall have occurred hereunder and be continuing, (B) no such increase shall cause the Aggregate Commitments to exceed $3,000,000,000, (C) no Lender’s Commitment shall be increased without such Lender’s consent, (D) such increase shall not result in the increase of any Borrower Sublimit and (E) such increase shall be evidenced by a commitment increase agreement in form and substance reasonably acceptable to the Administrative Agent and executed by WPZ, the Administrative Agent, the New Lenders, if any, and Lenders increasing their Commitments, if any, and which shall indicate the amount and allocation of such increase in the Aggregate Commitments and the effective date of such increase (the “Increase Effective Date”). Each financial institution that becomes a New Lender pursuant to this Section by the execution and delivery to the Administrative Agent of the applicable commitment increase agreement shall be a “Lender” for all purposes under this Agreement on the applicable Increase Effective Date. The Borrowers shall borrow and prepay Loans on each Increase Effective Date (and pay any additional amounts required pursuant to Section 2.16) to the extent necessary to keep the outstanding Loans of each Lender ratable with such Lender’s revised Applicable Percentage after giving effect to any nonratable increase in the Aggregate Commitments under this Section.

(ii) As a condition precedent to each increase pursuant to subsection (c)(i) above, WPZ shall deliver to the Administrative Agent, to the extent requested by the Administrative Agent, the following in form and substance reasonably satisfactory to the Administrative Agent:

(A) a certificate dated as of the Increase Effective Date, signed by a Responsible Officer of the General Partner certifying that each of the conditions to such increase set forth in this Section 2.01(c) shall have occurred and been complied with and that, before and after giving effect to such increase, (1) the representations and warranties (other than Added L/C Representations) contained in this Agreement and the other Loan Documents are true and correct in all material respects on and as of the Increase Effective Date after giving effect to such increase, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they were true and correct in all material respects as of such earlier date, and (2) no Default or Event of Default exists and is continuing;

(B) such certificates of resolutions or other action, incumbency certificates and/or other certificates of a Responsible Officer of the General Partner as the Administrative Agent may reasonably require evidencing the identity, authority and capacity of such Responsible Officer thereof authorized to act as a Responsible Officer in connection with such increase agreement, and such documents and certifications as the Administrative Agent may reasonably require to evidence that WPZ is validly existing and in good standing in its jurisdiction of organization; and

(C) a favorable customary opinion of counsel to WPZ, relating to such increase agreement, addressed to the Administrative Agent and each Lender if requested by the Administrative Agent or such Lenders.

(iii) Any Borrower shall have the option, by agreement with any Lender to (A) after consultation with the Administrative Agent, cause such Lender to become or cease to be an Issuing Bank under this Agreement and (B) increase or decrease the Letter of Credit Commitment of any Lender as an Issuing Bank.

Section 2.02 Loans and Borrowings.

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

(b) Subject to Section 2.14, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as a Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the applicable Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $5,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $5,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the Aggregate Commitments or, in the case of NWP or TGPL, the entire unused balance of the Borrower Sublimit

applicable to it, or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.06(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of 24 Eurodollar Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, no Borrower shall be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

Section 2.03 Requests for Borrowings. To request a Borrowing, a Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of the proposed Borrowing.

Section 2.06 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, any Borrower may request the issuance of Letters of Credit under the Commitments for its own account or for the account of any Subsidiary of it, in a form reasonably acceptable to the Administrative Agent and the applicable Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any Letter of Credit Document, the terms and conditions of this Agreement shall control. For the avoidance of doubt, any representations, warranties and events of default in any such letter of credit application or other agreement shall have no effect. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of any Borrower, any Borrower requesting a Letter of Credit for a Subsidiary of it shall be obligated to reimburse the applicable Issuing Bank hereunder for any and all drawings under such Letter of Credit, provided that, for the avoidance of doubt, WPZ shall not be obligated to reimburse any Issuing Bank for any drawing under a Letter of Credit requested by NWP or TGPL and issued or outstanding in support of any obligations of, or for the account of NWP, TGPL or any Subsidiary of NWP or TGPL. Each Borrower hereby acknowledges that the issuance of Letters of Credit for the account of its Subsidiaries (other than, in the case of WPZ, the issuance of Letters of Credit at the request of NWP or TGPL for the account of NWP, TGPL or any Subsidiary of NWP or TGPL) inures to the benefit of such Borrower, and that such Borrower’s business derives substantial benefits from the businesses of its Subsidiaries.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal (unless automatically renewed by its terms) or extension of an outstanding Letter of Credit), a Borrower shall hand deliver or fax (or transmit by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Administrative Agent three Business Days (or such shorter period as may be acceptable to such Issuing Bank) in advance of the requested date of issuance, amendment, renewal (unless automatically renewed by its terms) or extension, a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by such Issuing Bank, such Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended if and only if (and upon issuance, amendment, renewal or extension of each Letter of Credit such Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure in respect of all Letters of Credit issued by the Issuing Banks does not exceed the aggregate of all Letter of Credit Commitments at such time, (ii) the LC Exposure in respect of all Letters of Credit issued by any Issuing Bank does not exceed the Letter of Credit Commitment of such Issuing Bank at such time, and (iii) the sum of the total Credit Exposures shall not exceed the Aggregate Commitments.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is seven Business Days prior to the Maturity Date; provided, if a Borrower so requests, an Issuing Bank may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic renewal provisions (each, an “Auto-Renewal Letter of Credit”); provided that any such Auto-Renewal Letter of Credit must permit such Issuing Bank to prevent any such renewal at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not

later than (A) thirty (30) days before the end of such twelve-month period, or (B) such later date to be agreed upon at the time such Letter of Credit is issued (the “Nonrenewal Notice Date”). Once an Auto-Renewal Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) such Issuing Bank to permit the renewal of such Letter of Credit at any time prior to the date set forth in clause (ii) of this Section 2.06(c); provided that the expiry date of such Letter of Credit shall be no later than the date set forth in clause (ii) of this Section 2.06(c).

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

(e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the applicable Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement on the date that such LC Disbursement is made, if such Borrower shall have received notice of such LC Disbursement prior to 9:00 a.m., New York City time, on such date, or, if such notice has not been received by such Borrower prior to such time on such date, then on the Business Day immediately following the day that such Borrower receives such notice; provided that such Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Sections 2.03 that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, such Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If such Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from such Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from such Borrower, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the applicable Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from such Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the applicable Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders and the applicable Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse an Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve a Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. Each Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances

whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, any Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Banks, 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 an Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from liability to any Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by each Borrower to the extent permitted by applicable law) suffered by any Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of an Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, an Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

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

(h) Interim Interest. If an Issuing Bank shall make any LC Disbursement, then, unless the applicable Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that such Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if such Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.13(d) 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 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, after consultation with the Administrative Agent, by written agreement among the Borrowers, 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 Borrower shall pay all unpaid fees owed by it and accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or 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.

(i) If any Event of Default shall occur and be continuing and if the maturity of the Loans has been accelerated with respect to a Borrower pursuant to Article VII, on the Business Day that the Borrowers receive notice from the Administrative Agent upon written request of the Required Lenders demanding Cash Collateralization pursuant to this paragraph, each such applicable Borrower shall Cash Collateralize an amount in cash equal to the LC Exposure for all outstanding Letters of Credit requested by it as of such date plus any accrued and unpaid interest thereon; provided that the obligation to Cash Collateralize the LC Exposure shall become effective immediately, and such Cash Collateral 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 clause (g) or (h) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the applicable Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at each Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Banks for LC Disbursements for which they have not been reimbursed by the applicable Borrower and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the applicable Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 51% of the total LC Exposure), be applied to satisfy other obligations of the applicable Borrower under this Agreement. To the extent not applied as aforesaid, any cash collateral provided hereunder shall be returned in full to the applicable Borrower within three Business Days after all Events of Default have been cured or waived or, in full or in part, as necessary to cause the amount of such cash collateral not to exceed the aggregate LC Exposure.

(ii) If any Lender becomes, and during the period it remains, a Defaulting Lender, if any Letter of Credit is at the time outstanding, any Issuing Bank (unless such Issuing Bank is a Defaulting Lender), except to the extent the Commitments have been reallocated pursuant to Section 2.06(k), by notice to the applicable Borrower which requested or has requested the issuance of such Letters of Credit through the Administrative Agent, may require such applicable Borrower to Cash Collateralize within seven (7) Business Days the obligations of such Borrower to the Issuing Banks in respect of such Letters of Credit in an amount equal to the aggregate amount of the unreallocated obligations (contingent or otherwise) of such Defaulting Lender in respect thereof, or to make other arrangements satisfactory to the Administrative Agent and to the

applicable Issuing Bank(s) in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender. Any cash collateral provided pursuant to this clause (ii) shall be deposited in an interest bearing account promptly after the execution of the appropriate deposit account agreement and establishment of such account from which the Administrative Agent will release interest to the applicable Borrower on a periodic basis.

(k) Reallocation of Defaulting Lender Commitment, Etc. If a Lender becomes, and during the period it remains, a Defaulting Lender, the LC Exposure of such Defaulting Lender will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitments; provided that (a) the sum of each Non-Defaulting Lender’s total Credit Exposure may not in any event exceed the Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (b) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrowers, the Administrative Agent, the Issuing Banks or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender.

(l) Addition of Letters of Credit. If (i) an Issuing Bank has, at the request of a Borrower, issued a letter of credit in Dollars other than under this Agreement, (ii) such Borrower decides to add such letter of credit (an “Added Letter of Credit”) to this Agreement as a Letter of Credit and (iii) such Issuing Bank consents in writing (such consent, and any funding of a draw under such letter of credit, are deemed made by such Issuing Bank in reliance on the agreements of the other Lenders pursuant to this Section 2.06) to such letter of credit becoming an Added Letter of Credit, then such Borrower shall give the Administrative Agent and such Issuing Bank at least three Business Days’ (or such shorter period as agreed to by the Administrative Agent and such Issuing Bank) prior notice requesting that such letter of credit be so added, specifying the Business Day such letter of credit is to be added to this Agreement and attaching thereto a copy of such letter of credit, by hand delivering, faxing or transmitting by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank, to the applicable Issuing Bank and the Administrative Agent. On the Business Day so specified for such letter of credit, such letter of credit shall become an Added Letter of Credit and become a Letter of Credit deemed issued under this Agreement by the Issuing Bank specified in the relevant notice (the date such letter of credit so becomes an Added Letter of Credit being the “Added L/C Effective Date” for such letter of credit), if and only if (and, in the case of clauses (A) and (B) below, upon adding such letter of credit such Borrower shall be deemed to represent and warrant that), (A) after giving effect to such inclusion (w) the LC Exposure in respect of all Letters of Credit issued by the Issuing Banks does not exceed the aggregate of all Letter of Credit Commitments at such time, (x) the LC Exposure in respect of all Letters of Credit issued by any Issuing Bank does not exceed the Letter of Credit Commitment of such Issuing Bank at such time, (y) the sum of the total Credit Exposures shall not exceed the Aggregate Commitments and (z) the sum of the total Credit Exposures with respect to NWP or TGPL do not exceed in each case the Borrower Sublimit, (B) such letter of credit complies in all other respects with this Section 2.06, and (C) such Issuing Bank notifies the Administrative Agent, on or before such Added L/C Effective Date, that such letter of credit is or will become, as of such Added L/C Effective Date, an Added Letter of Credit.

(m) Existing Letters of Credit. The parties hereto acknowledge and agree that all Existing Letters of Credit are deemed to be issued under this Agreement by the applicable Issuing Bank at the request of the applicable Borrower and shall constitute Letters of Credit hereunder for all purposes (including Section 2.06(d) and Section 2.06(e)), and no notice requesting issuance thereof shall be required hereunder. Each reference herein to the issuance of a Letter of Credit shall include any such deemed issuance. All fees accrued on the Existing Letters of Credit to but excluding the date hereof shall be for the account of the applicable “Issuing Bank” and the “Lenders” (as those terms are used in the

Existing Credit Agreement) as provided in the Existing Credit Agreement, and all fees accruing on the Existing Letters of Credit on and after the date hereof shall be for the account of the applicable Issuing Bank thereof and the Lenders as provided herein.

Section 2.07 Funding of Borrowings.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the applicable Borrower by promptly crediting the amounts so received, in like funds, to an account 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 2.06(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 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 this Section 2.07 and may, but shall not be required to, 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 the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the applicable 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 a payment to be made by 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 and (ii) in the case of a payment to be made by such Borrower, the interest rate applicable to ABR Loans. If such Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the applicable Borrower the amount of such interest paid by such Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any payment by the applicable Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

Section 2.08 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. Thereafter, the applicable Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. Such Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) To make an election pursuant to this Section, the applicable Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if such Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election

Request shall be irrevocable and shall be confirmed promptly by hand delivery, fax or emailed pdf to the Administrative Agent of a written Interest Election Request signed by such Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.03:

(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 such 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 with respect to any Borrower and the Administrative Agent, at the request of the Required Lenders, so notifies such Borrower, then, so long as an Event of Default with respect to such Borrower is continuing (i) no outstanding Borrowing of such Borrower may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Borrowing of such Borrower shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.09 Termination and Reduction of Commitments.

(a) Unless previously terminated, the Aggregate Commitments shall terminate on the Maturity Date.

(b) WPZ may at any time terminate, or from time to time reduce, the Aggregate Commitments or the Letter of Credit Commitments and NWP and TGPL may at any time terminate, or from time to time reduce, the Borrower Sublimit applicable to such Borrower; provided that (i) each reduction of the Aggregate Commitments, the Letter of Credit Commitments or any Borrower Sublimit shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000, (ii) WPZ shall not terminate or reduce the Aggregate Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the sum of the Credit Exposures would exceed the Aggregate Commitments, (iii) WPZ shall not terminate or reduce the Letter of Credit Commitments if the LC Exposure would exceed the Letter of Credit Commitments, as so reduced, (iv) the amount of the

Letter of Credit Commitment of any Issuing Bank shall not be reduced to an amount which is less than the aggregate amount of LC Exposure in respect of all Letters of Credit issued or deemed issued by such Issuing Bank; (v) the Borrower Sublimit for any Borrower may not be reduced to an amount which is less than the greatest, for such Borrower, of the sum of (A) the aggregate outstanding principal amount of Loans owed by such Borrower plus (B) the aggregate amount of LC Exposure in respect of Letters of Credit issued at the request of such Borrower; and (vi) the Aggregate Commitments shall not be reduced to an amount which is less than the aggregate amount of the Letter of Credit Commitments, unless the Letter of Credit Commitments are correspondingly reduced at the same time. When NWP or TGPL ceases to be a Borrower, the Borrower Sublimit applicable to such Borrower shall be terminated, such Borrower shall repay all obligations under the Loan Documents owing by it and all Letters of Credit issued at the request of such Borrower shall be terminated or such Borrower shall provide cash collateral to the Agent in an amount equal to the undrawn face amount of such Letters of Credit.

(c) The applicable Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Commitments, the Letter of Credit Commitments or a Borrower Sublimit under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by a Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Aggregate Commitments or the Letter of Credit Commitments delivered by any Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities or another event, in which case such notice may be revoked by such Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Aggregate Commitments, the Letter of Credit Commitments or a Borrower Sublimit shall be permanent; provided that nothing in this provision shall affect a Borrower’s ability to increase the Letter of Credit Commitments pursuant to Section 2.01(c)(iii). Each reduction of the Aggregate Commitments and a Borrower Sublimit shall be made ratably among the Lenders in accordance with their respective Commitments, except as provided in clause (d) below. Each reduction of the Letter of Credit Commitments being made in conjunction with a reduction of the Aggregate Commitments pursuant to Section 2.09(b)(vi) above shall be made ratably among the Issuing Banks in accordance with their respective Letter of Credit Commitments.

(d) WPZ may terminate the unused amount of the Commitment and Letter of Credit Commitment of a Defaulting Lender upon one Business Day’s prior notice to the Administrative Agent (which will promptly notify the Lenders thereof), provided that such termination will not be deemed to be a waiver or release of any claim the Borrowers, the Administrative Agent, the Issuing Banks or any Lender may have against such Defaulting Lender.

(e) Notwithstanding any other provision of this Section 2.09, if at any time, WPZ ceases to have Control over, and/or ceases to maintain NWP or TGPL as its Subsidiary, then the Borrower Sublimit applicable to such Borrower shall automatically terminate, such Borrower shall repay all obligations owing by it under the Loan Documents and all Letters of Credit issued at the request of such Borrower shall be terminated or such Borrower shall provide cash collateral to the Agent in an amount equal to the undrawn face amount of such Letters of Credit or make other arrangements satisfactory to the relevant Issuing Bank(s) with respect to such Letters of Credit, it being understood that the termination of a Borrower Sublimit for either NWP or TGPL shall not result in a reduction of the Aggregate Commitments.

(f) Notwithstanding the foregoing, all of the provisions of the Loan Documents which by their terms survive termination of the Commitments of a Borrower, including, without limitation, those

provisions set forth in Section 9.06, shall survive and not be deemed terminated, but shall remain in full force and effect.

Section 2.10 Repayment of Loans; Evidence of Debt.

(a) Each Borrower hereby unconditionally promises to pay to the Administrative Agent for the ratable account of each Lender the then unpaid principal amount of each Loan (and all accrued and unpaid interest thereon) made to such Borrower on the Maturity Date.

(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, 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 and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of 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 promissory note. In such event, each Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender and substantially in the form of note attached hereto as Exhibit E. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.05) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

Section 2.11 Prepayment of Loans.

(a) Each Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section.

(b) The applicable Borrower shall notify the Administrative Agent by telephone (confirmed by hand delivery, fax or emailed pdf) of any prepayment hereunder not later than 11:00 a.m., 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, any such notice of prepayment may be conditioned upon the effectiveness of other credit facilities or another event. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13.

Section 2.12 Fees.

(a) WPZ agrees to pay to the Administrative Agent for the account of each Lender (other than a Defaulting Lender) a commitment fee on the daily average unused amount of the Commitment of such Lender for the period from and including the Effective Date up to, but excluding, the date on which the Aggregate Commitments have been terminated at the Applicable Rate for commitment fees. Accrued commitment fees shall be payable in arrears on the last Business Day of March, June, September and December of each year and on the date on which the Aggregate Commitments terminate, commencing on the first such date to occur after the Effective Date. All commitment 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).

(b) Each Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender (other than a Defaulting Lender) a participation fee with respect to its participations in Letters of Credit (other than with respect to Letters of Credit which have been Cash Collateralized to the extent of such Cash Collateralization) issued at the request of such Borrower, which shall accrue at the same Applicable Rate as interest on 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 date on which such Lender ceases to have any LC Exposure, and (ii) to the applicable Issuing Bank a fronting fee, which shall accrue at the rate of 0.15% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the date on which there ceases to be any LC Exposure, as well as such Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable quarterly on the third Business Day following the last day of March, June, September and December of each year, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Aggregate Commitments terminate and any such fees accruing after the date on which the Aggregate Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Banks pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting 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). All fees accrued on a letter of credit that becomes an Added Letter of Credit, to but excluding the Added L/C Effective Date for such Added Letter of Credit shall be for the account of the entity that issued such Added Letter of Credit, and all fees accruing on such letter of credit on and after such Added L/C Effective Date shall be for the account of the relevant Issuing Bank thereof and the Lenders as provided herein.

(c) WPZ agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between WPZ and the Administrative Agent as set forth in the applicable Fee Letter.

(d) WPZ agrees to pay to each Joint Lead Arranger, for its own account, fees payable in the amounts and at the times separately agreed upon among WPZ and such Joint Lead Arranger as set forth in the applicable Fee Letter.

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

(f) Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to this Section 2.12 (without prejudice to the rights of the Lenders other than Defaulting Lenders in respect of such fees) nor shall any such fee be payable by any Borrower, provided that (a) for the avoidance of doubt and without duplication of fees, to the extent that a portion of the LC Exposure of such Defaulting Lender is reallocated to the Non-Defaulting Lenders pursuant to Section 2.06(k), such fees that would have accrued for the benefit of such Defaulting Lender will instead accrue for the benefit of and be payable to such Non-Defaulting Lenders (other than with respect to Letters of Credit which have been Cash Collateralized to the extent of such Cash Collateralization), pro rata in accordance with their respective Commitments, and (b) to the extent any portion of such LC Exposure cannot be so reallocated, such fees will instead accrue for the benefit of and be payable to the Issuing Banks as their interests appear (and the pro rata payment provisions of Section 2.18 will automatically be deemed adjusted to reflect the provisions of this Section).

Section 2.13 Interest.

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

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

(c) Notwithstanding the foregoing, upon the occurrence and during the continuance of any Event of Default with respect to any Borrower, if any principal of or interest on any Loan or any fee or other amount payable by such 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 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.

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

(e) All interest determined by reference to the LIBO Rate or clauses (b) or (c) of the definition of Alternate Base Rate shall be computed on the basis of a year of 360 days, and all other interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

(f) Any Borrower (with respect to Loans made to it) shall pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System of the United States of America to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Borrowing of such Lender during such periods as such Borrowing is a Eurodollar Borrowing, from the date of such

Borrowing until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the LIBO Rate for the Interest Period in effect for such Eurodollar Borrowing from (ii) the rate obtained by dividing such LIBO Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period. Such additional interest shall be determined by such Lender. Any Borrower (with respect to Loans made to it) shall from time to time, within 15 days after demand (which demand shall be accompanied by a certificate comporting with the requirements set forth in Section 2.15(c)) by such Lender (with a copy of such demand and certificate to the Administrative Agent) pay to the Lender giving such notice such additional interest; provided, however, that no Borrower shall be required to pay to such Lender any portion of such additional interest that accrued more than 90 days prior to any such demand, unless such additional interest was not determinable on the date that is 90 days prior to such demand.

Section 2.14 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

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

(b) the Administrative Agent is advised by the Required Lenders that 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; provided that if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

Section 2.15 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender Party;

(ii) subject any Recipient to any Tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Recipient in respect thereof (except for any Indemnified Taxes covered by Section 2.17 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Recipient); or

(iii) impose on any Lender Party or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender Party of making, funding or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender Party of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender Party hereunder (whether of principal, interest or any other amount) then, upon request of such Lender Party, the applicable Borrower will pay to such Lender Party such additional amount or amounts as will compensate such Lender Party for such additional costs incurred or reduction suffered, in each case to the extent applicable to the Loans or LC Exposure related to such Borrower.

(b) Capital Requirements. If any Lender Party determines that any Change in Law affecting such Lender Party or any lending office of such Lender Party or such Lender Party’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender Party’s capital or on the capital of such Lender Party’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender 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 Party or such Lender Party’s holding company could have achieved but for such Change in Law (taking into consideration such Lender Party’s policies and the policies of such Lender Party’s holding company with respect to capital adequacy or liquidity), then from time to time the applicable Borrower will pay to such Lender Party such additional amount or amounts as will compensate such Lender Party or such Lender Party’s holding company for any such reduction suffered, in each case to the extent applicable to the Loans or LC Exposure related to such Borrower.

(c) Certificates for Reimbursement. A certificate of a Lender Party setting forth the amount or amounts necessary to compensate such Lender Party or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section, showing the computation thereof and delivered to the applicable Borrower shall be conclusive absent manifest error. Such certificate shall further certify that such Lender Party is making similar demands of its other similarly situated borrowers. Any applicable Borrower shall pay such Lender Party the amount shown as owed by it and due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender Party to demand compensation pursuant to this Section shall not constitute a waiver of such Lender Party’s right to demand such compensation, provided that no Borrower shall be required to compensate a Lender Party pursuant to this Section for any increased costs incurred or reductions suffered more than ninety days prior to the date that such Lender Party notifies such Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender Party’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the ninety day period referred to above shall be extended to include the period of retroactive effect thereof).

Section 2.16 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(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 the Borrowers pursuant to Section 2.19, then, in any such event, the applicable Borrower shall compensate each Lender for the loss, cost and expense (excluding loss of anticipated profits) attributable to such event. A certificate of any Lender setting forth, in reasonable detail showing the computation thereof, 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. Such Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof, if such certificate complies herewith.

Section 2.17 Taxes.

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

(b) Payment of Other Taxes by Borrowers. Without limiting the provisions of paragraph (a) above, each Borrower shall timely pay any Other Taxes related to it to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by Borrowers. Each Borrower shall indemnify the Administrative Agent and each Lender Party, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient 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 Party (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender Party shall be conclusive absent manifest error.

(d) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrowers have not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of any Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.05(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Borrower, and any reasonable expenses arising therefrom or with respect thereto, whether or not such 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 any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (d).

(e) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower to a Governmental Authority pursuant to this Section 2.17, 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.

(f) Status of Lenders.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the applicable Borrower and the Administrative Agent, at the time or times prescribed by applicable law or reasonably requested by the Borrowers or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrowers or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrowers or the Administrative Agent, shall deliver such other documentation prescribed by applicable requirement of law or reasonably requested by the Borrowers or the Administrative Agent as will enable the Borrowers or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

(ii) Without limiting the generality of the foregoing,

(A) any Lender that is a U.S. Person shall deliver to the Borrowers and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of a Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding Tax;

(B) any Foreign Lender shall deliver to the Borrowers and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of a Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable: (i) in the case of a Foreign Lender claiming the benefits of an income Tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such Tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such Tax treaty; (ii) executed originals of IRS Form W-8ECI; (iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of

Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of any Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or (iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrowers and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of a Borrower or the Administrative Agent), executed originals of any other form prescribed by an applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrowers or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to any withholding Tax imposed by FATCA if such Lender were to fail to comply with the requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code), such Lender shall deliver to the Borrowers and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrowers or the Administrative Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrowers or the Administrative Agent as may be necessary for the Borrowers and the Administrative Agent to comply with their obligations under FATCA, to determine that such Lender has or has not complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrowers and the Administrative Agent in writing of its legal inability to do so.

(g) Treatment of Certain Refunds. If any Recipient receives a refund of any Taxes as to which it has been indemnified by the Borrowers or with respect to which the Borrowers have paid pursuant to this Section 2.17 (including by the payment of additional amounts pursuant to this Section 2.17), such Recipient shall pay to the Borrowers an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid by the Borrowers under this Section with respect to the Taxes giving rise to such refund), net of reasonable out-of-pocket expenses directly related to the receipt of such refund by the Recipient and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund) provided that, the Borrowers, upon the request of such Recipient, agree to repay the amount paid over to the Borrowers pursuant to this paragraph (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Recipient in the event the Recipient is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (g), in no event will the applicable Recipient be required to pay any amount to the Borrowers pursuant to this paragraph (g) the payment of which would place such Recipient in a less favorable net after-Tax position than the Recipient would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require the Administrative Agent or Any Lender Party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Borrowers or any other Person.

(h) Survival. Each party’s obligations under this Section 2.17 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender,

the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

Section 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Each Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to 1:00 p.m., 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 date of such payment or on the next succeeding Business Day for purposes of calculating interest and fees thereon. All such payments shall be made to the Administrative Agent at its offices at Citicorp North America, 390 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Xxxxxxxx Partners L.P. Account Officer, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.04 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) 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 any 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 any 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 this subsection (c) may exercise against such Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

(d) [Reserved].

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Sections 2.06(d), 2.06(e), 2.07(b), or 9.04(c), 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 2.19 Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.13(f) or Section 2.15 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 2.17, 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 Sections 2.13(f), 2.15 or 2.17, 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. Any applicable Borrower required to make any payment under Sections 2.13(f), 2.15 or 2.17 hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. Subject to the foregoing, Lenders agree to use reasonable efforts to select lending offices which will minimize taxes and other costs and expenses for the Borrowers.

(b) If any Lender requests compensation under Section 2.13(f) or Section 2.15, 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 2.17, or if any Lender is a Defaulting Lender, or if any Lender fails to approve an amendment, waiver or other modification to this Agreement that requires the approval of all Lenders and at least the Required Lenders have approved such amendment, waiver or other modification, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.05), 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 Borrowers shall have received the prior written consent of the Administrative Agent and the Issuing Banks, which consent shall not unreasonably be withheld or delayed, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.16), from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the applicable Borrower or 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(f) or Section 2.15 or payments required to be made pursuant to Section 2.17, 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 Borrowers to require such assignment and delegation cease to apply. If any Lender refuses to assign and delegate all its interests, rights and obligations under this Agreement after the Borrowers have required such Lender to do so as a result of a claim for compensation under Section 2.13(f) or Section 2.15 or payments required to be made pursuant to Section 2.17, such Lender shall not be entitled to receive such compensation or required payments.

(c) If the Borrowers, the Administrative Agent and the Issuing Banks agree in writing in their discretion that a Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will, to the extent

applicable, purchase such portion of outstanding Loans of the other Lenders and/or make such other adjustments as the Administrative Agent may determine to be necessary to cause the Credit Exposure of the Lenders to be on a pro rata basis in accordance with their respective Commitments, whereupon such Lender will cease to be a Defaulting Lender and will be a Non-Defaulting Lender (and such Credit Exposure of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while such Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender having been a Defaulting Lender.

Section 2.20 Nature of Obligations. Notwithstanding anything in this Agreement to the contrary, the respective obligations of the Borrowers under the Loan Documents are several and not joint. For avoidance of doubt, and without limitation of the preceding sentence, it is agreed that (i) no Borrower shall be liable for the Loans (or interest or fees with respect thereto) made to a different Borrower under Section 2.01, and no Borrower shall be liable for the LC Disbursements (or related fees) with respect to Letters of Credit issued at the request of a different Borrower pursuant to Section 2.06, (ii) with respect to each Borrower, the obligations set forth in Section 2.15 shall only apply in respect of the Commitment of any Lender Party to lend to, or to issue (or purchase participations in) Letters of Credit issued at the request of, such Borrower, (iii) with respect to the indemnification obligations set forth in Section 2.17, each Borrower shall only be responsible for such obligations that result from Taxes or Other Taxes in connection with Loans made to, or Letters of Credit issued at the request of, or that otherwise pertain to, such Borrower or any of its Subsidiaries, (iv) with respect to any representation and warranty made by a Borrower pursuant to Section 4.02, such representation and warranty shall only be made by such Borrower as provided in clause (v) of this Section 2.20, (v) with respect to the representations and warranties made in Article III or, if applicable, any other Loan Document, each Borrower makes such representations and warranties only with respect to, and only to the extent applicable to, such Borrower and its Subsidiaries, and (vi) with respect to covenants set forth in Articles V and VI, each Borrower is only responsible for compliance with such covenants only with respect to, and only to the extent applicable to, such Borrower and its Subsidiaries.

ARTICLE III

REPRESENTATIONS AND WARRANTIES

Each Borrower, solely with respect to itself and, to the extent set forth below, its Subsidiaries, represents and warrants to the Lenders that, on the Effective Date, on the date of each Borrowing by such Borrower or issuance or increase in the amount of any Letter of Credit for such Borrower and each Added L/C Effective Date, except with respect to Sections 3.07 and 3.08 in each case as specified therein, which shall only be represented and warranted as of the Effective Date as provided therein:

Section 3.01 Organization; Powers. Such Borrower and each of its Material Subsidiaries is validly existing and (if applicable) in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business in all material respects as now conducted and is qualified to do business in, and (if applicable) is in good standing in, every jurisdiction where such qualification is required, except where the failure to do so or to be validly existing and in good standing or to have such power and authority, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

Section 3.02 Authorization; Enforceability. The Transactions and the performance of its obligations contemplated thereby are within such Borrower’s partnership or limited liability company powers, as applicable, and have been duly authorized by all necessary partnership, limited liability

company and, if required, partner action, as applicable. This Agreement has been duly executed and delivered by such Borrower and constitutes a legal, valid and binding obligation of such Borrower, enforceable against such Borrower in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

Section 3.03 Governmental Approvals; No Conflicts. No material 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 such Borrower of any Loan Document to which it is a party, or the consummation of the transactions contemplated thereby. The execution, delivery and performance by such Borrower of the Loan Documents to which it is shown as being a party and the consummation of the transactions contemplated thereby do not contravene (a) such Borrower’s organizational documents or (b) any law or any restriction under any material agreement binding on or affecting such Borrower and will not result in or require the creation or imposition of any Lien prohibited by this Agreement.

Section 3.04 Financial Condition. WPZ has heretofore furnished to the Lenders its consolidated balance sheet and statements of income and cash flows (a) as of and for the fiscal year ended December 31, 2012, reported on by Ernst & Young LLP, independent public accountants, and (b) as of and for the fiscal quarter and the portion of the fiscal year ended March 31, 2013. Such financial statements (i) were prepared in accordance with GAAP, except as otherwise expressly noted therein, and (ii) present fairly, in all material respects, the financial position and results of operations and cash flows of the businesses of WPZ and its consolidated subsidiaries as of such dates and for such periods in accordance with GAAP.

Section 3.05 Litigation. Except as set forth in the annual report on Form 10-K for the year ended December 31, 2012 or the quarterly reports on Form 10-Q filed subsequent thereto but prior to the Closing Date of any Borrower, there are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of such Borrower, threatened in writing against such Borrower or any of its Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination and that would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect with respect to such Borrower or (ii) that purport to adversely affect the legality, validity and enforceability of the Loan Documents and are non-frivolous (as reasonably determined by the Administrative Agent); provided, that this representation, when made, shall not constitute an admission that any action, suit or proceeding set forth in any annual report on Form 10-K or any quarterly report on Form 10-Q referred to above would result in a Material Adverse Effect due to an adverse determination, if any.

Section 3.06 Environmental Matters. Except as set forth in the annual report on Form 10-K for the year ended December 31, 2012 or the quarterly reports on Form 10-Q filed subsequent thereto but prior to the Closing Date of any Borrower, such Borrower and its Subsidiaries have reasonably concluded that they: (a) are in compliance with all applicable Environmental Laws, except to the extent that any non-compliance would not reasonably be expected to have a Material Adverse Effect with respect to such Borrower; (b) are not subject to any judicial, administrative, government, regulatory or arbitration proceeding alleging the violation of any applicable Environmental Laws, except to the extent that any such proceeding would not reasonably be expected to have a Material Adverse Effect with respect to such Borrower; (c) are not subject to any federal, state, local or foreign review, audit or investigation which would reasonably be expected to lead to a proceeding referred to in (b) above that would reasonably be expected to have a Material Adverse Effect with respect to such Borrower; (d) have no actual knowledge that any of their predecessors in title to any of their property and assets are the subject of any currently pending federal, state, local or foreign review, audit or investigation which would reasonably be expected to lead to a proceeding referred to in (b) above that would reasonably be expected to have a Material

Adverse Effect with respect to such Borrower; and (e) possess, and are in compliance with, or have applied for, all approvals, licenses, permits, consents and other authorizations which are necessary under any applicable Environmental Laws to conduct their business, except to the extent that the failure to possess, or be in compliance with, any of the foregoing would not reasonably be expected to have a Material Adverse Effect with respect to such Borrower.

Section 3.07 Disclosure.

(k) an ERISA Event shall have occurred and, thirty (30) days after notice thereof shall have been given to such Borrower by the Administrative Agent, such ERISA Event shall still exist, and such ERISA Event, when taken together with all other ERISA Events that have occurred, would reasonably be expected to result in a Material Adverse Effect;

(l) such Borrower or any Material Subsidiary or ERISA Affiliate of such Borrower shall have been notified by the sponsor of a Multiemployer Plan that it has incurred Withdrawal Liability to such Multiemployer Plan in an amount which, when aggregated with all other amounts required to be paid to Multiemployer Plans in connection with Withdrawal Liabilities (determined as of the date of such notification), would reasonably be expected to result in a Material Adverse Effect;

(n) the General Partner takes, suffers or permits to exist any of the events or conditions referred to in clauses (g), (h) or (i) of this Article;

(o) a Change in Control shall occur; or

(p) if any Guaranty of a Material Subsidiary is required to be in effect pursuant to Section 5.09(a) and prior to the release of such Guaranty pursuant to Section 5.09(b), (i) such Guaranty for any reason is not a legal, valid, binding and enforceable obligation of such Guarantor party thereto for more than five (5) days or (ii) such Guarantor shall so state in writing that such Guaranty for any reason is not a legal, valid, binding and enforceable obligation of such Guarantor;

then, and in every such event (other than an event with respect to any Borrower described in clause (g) or (h) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent at the request of the Required Lenders shall, by notice to the Borrowers or applicable Borrower, take any of the following actions, at the same or different times: (i) terminate the Aggregate Commitments and Letter of Credit Commitments, and thereupon the Aggregate Commitments and the Letter of Credit Commitments shall terminate immediately, (ii) declare the Loans owed by the applicable

Borrower as to which an Event of Default has occurred and is continuing to be 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 such Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrowers; and in case of any event with respect to any Borrower described in clause (g) or (h) of this Article, the Borrower Sublimit of the Borrower as to which such Event of Default has occurred and is outstanding, the obligations of each Lender to make Loans to such Borrower, and of each Issuing Bank to issue a Letter of Credit for or on behalf of such Borrower shall be automatically terminated and the principal of the Loans of such Borrower then outstanding, together with accrued interest thereon and all fees and other obligations owed by the applicable Borrower as to which such Event of Default has occurred and is continuing, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrowers, and (iii) exercise on behalf of itself, the Lenders and the Issuing Banks all rights and remedies available to it, the Lenders and the Issuing Banks under the Loan Documents, including the rights under Section 2.06(j)(i).

ARTICLE VIII

THE ADMINISTRATIVE AGENT

Section 8.01 Appointment and Authority. Each Lender Party hereby irrevocably appoints Citibank, N.A. to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Lender Parties, and no Borrower or Guarantor shall have rights as a third party beneficiary of any of such provisions.

Section 8.02 Administrative Agent Individually.

(a) The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender Party as any other Lender Party and may exercise the same as though it were not the Administrative Agent and the term “Lender Party” or “Lender Parties” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with any Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lender Parties.

(b) Each Lender Party understands that the Person serving as Administrative Agent, acting in its individual capacity, and its Affiliates (collectively, the “Agent’s Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research) (such services and businesses are collectively referred to in this Article VIII as “Activities”) and may engage in the Activities with or on behalf of one or more of the Borrowers or their respective Affiliates. Furthermore, the Agent’s Group may, in undertaking the Activities, engage in trading in financial products or undertake other investment businesses for its own

account or on behalf of others (including the Borrowers and their Affiliates and including holding, for its own account or on behalf of others, equity, debt and similar positions in the Borrowers or its respective Affiliates), including trading in or holding long, short or derivative positions in securities, loans or other financial products of one or more of the Borrowers or their Affiliates. Each Lender Party understands and agrees that in engaging in the Activities, the Agent’s Group may receive or otherwise obtain information concerning the Borrowers or their Affiliates (including information concerning the ability of the Borrowers to perform its obligations hereunder and under the other Loan Documents) which information may not be available to any of the Lender Parties that are not members of the Agent’s Group. None of the Administrative Agent nor any member of the Agent’s Group shall have any duty to disclose to any Lender Party or use on behalf of the Lender Parties, and shall not be liable for the failure to so disclose or use, any information whatsoever about or derived from the Activities or otherwise (including any information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of the Borrowers or any Affiliate thereof) or to account for any revenue or profits obtained in connection with the Activities, except that the Administrative Agent shall deliver or otherwise make available to each Lender Party such documents as are expressly required by any Loan Document to be transmitted by the Administrative Agent to the Lender Parties.

(c) Each Lender Party further understands that there may be situations where members of the Agent’s Group or their respective customers (including the Borrowers and their Affiliates) either now have or may in the future have interests or take actions that may conflict with the interests of any one or more of the Lender Parties (including the interests of the Lender Parties hereunder and under the other Loan Documents). Each Lender Party agrees that no member of the Agent’s Group is or shall be required to restrict its activities as a result of the Person serving as Administrative Agent being a member of the Agent’s Group, and that each member of the Agent’s Group may undertake any Activities without further consultation with or notification to any Lender Party. None of (i) this Agreement nor any other Loan Document, (ii) the receipt by the Agent’s Group of information (including Information) concerning the Borrowers or their Affiliates (including information concerning the ability of the Borrowers to perform their respective obligations hereunder and under the other Loan Documents) nor (iii) any other matter shall give rise to any fiduciary, equitable or contractual duties (including without limitation any duty of trust or confidence) owing by the Administrative Agent or any member of the Agent’s Group to any Lender Party including any such duty that would prevent or restrict the Agent’s Group from acting on behalf of customers (including the Borrowers or their Affiliates) or for its own account.

Section 8.03 Duties of Administrative Agent; Exculpatory Provisions.

(a) The Administrative Agent’s duties hereunder and under the other Loan Documents are solely ministerial and administrative in nature and the Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, but shall be required to act or refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written direction of the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent or any of its Affiliates to liability or that is contrary to any Loan Document or applicable law, including, for the avoidance of doubt, any action that may be in violation of the automatic stay under the Bankruptcy Code or other debtor relief law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of the Bankruptcy Code or other debtor relief law.

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the

Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 9.03 or Article VII) or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default or the event or events that give or may give rise to any Default unless and until any Borrower or any Lender Party shall have given notice to the Administrative Agent describing such Default and such event or events.

(c) Neither the Administrative Agent nor any member of the Agent’s Group shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty, representation or other information made or supplied in or in connection with this Agreement, any other Loan Document or the Information Memorandum, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith or the adequacy, accuracy and/or completeness of the information contained therein, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than (but subject to the foregoing clause (ii)) to confirm receipt of items expressly required to be delivered to the Administrative Agent.

(d) Nothing in this Agreement or any other Loan Document shall require the Administrative Agent or any of its Related Parties to carry out any “know your customer” or other checks in relation to any person on behalf of any Lender Party and each Lender Party confirms to the Administrative Agent that it is solely responsible for any such checks it is required to carry out and that it may not rely on any statement in relation to such checks made by the Administrative Agent or any of its Related Parties.

Section 8.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender Party, the Administrative Agent may presume that such condition is satisfactory to such Lender Party unless an officer of the Administrative Agent responsible for the transactions contemplated hereby shall have received notice to the contrary from such Lender Party prior to the making of such Loan or the issuance of such Letter of Credit, and in the case of a Borrowing, such Lender Party shall not have made available to the Administrative Agent such Lender Party’s ratable portion of such Borrowing. The Administrative Agent may consult with legal counsel (who may be counsel for any Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 8.05 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub agents appointed by the Administrative Agent. The Administrative Agent and any such sub agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. Each such sub agent and the Related Parties of the Administrative Agent and each such sub agent shall be entitled to the benefits of all provisions of this Article VIII and Section 9.04 (as though such sub-agents were the “Administrative Agent” under the Loan Documents) as if set forth in full herein with respect thereto.

Section 8.06 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lender Parties and the Borrowers (such notice not to be effective until 30 days have lapsed). Upon receipt of any such notice of resignation, the Required Lenders shall have the right, unless an Event of Default under subsection (a), (g) or (h) of Article VIII has occurred and is continuing, with the consent of the Borrowers, to appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (such 30-day period, the “Lender Party Appointment Period”), then the retiring Administrative Agent may on behalf of the Lender Parties, appoint a successor Administrative Agent meeting the qualifications set forth above. In addition and without any obligation on the part of the retiring Administrative Agent to appoint, on behalf of the Lender Parties, a successor Administrative Agent, the retiring Administrative Agent may at any time upon or after the end of the Lender Party Appointment Period notify the Borrowers and the Lender Parties that no qualifying Person has accepted appointment as successor Administrative Agent and the effective date of such retiring Administrative Agent’s resignation which effective date shall be no earlier than three business days after the date of such notice. Upon the resignation effective date established in such notice and regardless of whether a successor Administrative Agent has been appointed and accepted such appointment, the retiring Administrative Agent’s resignation shall nonetheless become effective and (i) the retiring Administrative Agent shall be discharged from its duties and obligations as Administrative Agent hereunder and under the other Loan Documents and (ii) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender Party directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties as Administrative Agent of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations as Administrative Agent hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by WPZ to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between WPZ and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 9.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent. Anything herein to the contrary notwithstanding, if at any time the Required Lenders determine that the Person serving as Administrative Agent is (without taking into account any provision in the definition of “Defaulting Lender” requiring notice from the Administrative Agent or any other party) a Defaulting Lender, the Required Lenders (determined after giving effect to Section 9.03) may by notice to the Borrowers and such Person remove such Person as Administrative Agent and, in with the consent of the Borrowers, appoint a replacement Administrative Agent hereunder. Such removal will, to the fullest extent permitted by applicable law, be effective on the earlier of (i) the date a replacement Administrative Agent is appointed and (ii) the date 30 days after the giving of such notice by the Required Lenders (regardless of whether a replacement Administrative Agent has been appointed).

Section 8.07 Non-Reliance on Administrative Agent and Other Lender Parties.

(a) Each Lender Party confirms to the Administrative Agent, each other Lender Party and each of their respective Related Parties that it (i) possesses (individually or through its Related Parties) such knowledge and experience in financial and business matters that it is capable, without reliance on the Administrative Agent, any other Lender Party or any of their respective Related Parties, of evaluating the merits and risks (including tax, legal, regulatory, credit, accounting and other financial matters) of (x) entering into this Agreement, (y) making Loans and other extensions of credit hereunder and under the other Loan Documents and (z) taking or not taking actions hereunder and thereunder, (ii) is financially able to bear such risks and (iii) has determined that entering into this Agreement and making Loans and other extensions of credit hereunder and under the other Loan Documents is suitable and appropriate for it.

(b) Each Lender Party acknowledges that (i) it is solely responsible for making its own independent appraisal and investigation of all risks arising under or in connection with this Agreement and the other Loan Documents, (ii) it has, independently and without reliance upon the Administrative Agent, any other Lender Party or any of their respective Related Parties, made its own appraisal and investigation of all risks associated with, and its own credit analysis and decision to enter into, this Agreement based on such documents and information as it has deemed appropriate and (iii) it will, independently and without reliance upon the Administrative Agent, any other Lender Party or any of their respective Related Parties, continue to be solely responsible for making its own appraisal and investigation of all risks arising under or in connection with, and its own credit analysis and decision to take or not take action under, this Agreement and the other Loan Documents based on such documents and information as it shall from time to time deem appropriate, which may include, in each case:

(i) the financial condition, status and capitalization of the Borrowers;

(ii) the legality, validity, effectiveness, adequacy or enforceability of this Agreement and each other Loan Document and any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Loan Document;

(iii) determining compliance or non-compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit and the form and substance of all evidence delivered in connection with establishing the satisfaction of each such condition;

(iv) the adequacy, accuracy and/or completeness of the Information Memorandum and any other information delivered by the Administrative Agent, any other Lender Party or by any of their respective Related Parties under or in connection with this Agreement or any other Loan Document, the transactions contemplated hereby and thereby or any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Loan Document.

Section 8.08 No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Persons acting as Joint Bookrunners, Joint Lead Arrangers or Co-Syndication Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent or as a Lender Party hereunder.

Section 8.09 Trust Indenture Act. In the event that Citibank, N.A. or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by any Borrower or any Guarantor, the parties

hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of such Borrower or such Guarantor hereunder or under any other Loan Document by or on behalf of Citibank, N.A. in its capacity as the Administrative Agent for the benefit of any Lender under any Loan Document (other than Citibank, N.A. or an Affiliate of Citibank, N.A.) and which is applied in accordance with the Loan Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

Section 8.10 Resignation of an Issuing Bank. If a Lender becomes, and during the period it remains, a Defaulting Lender, and Commitments have not been fully reallocated pursuant to Section 2.06(k)), an Issuing Bank may, upon prior written notice to the Borrowers and the Administrative Agent, resign as an Issuing Bank effective at the close of business New York time on a date specified in such notice; provided, that such resignation by an Issuing Bank will have no effect on the validity or enforceability of any Letter of Credit then outstanding or on the obligations of the Borrowers or any Lender under this Agreement with respect to any such outstanding Letter of Credit or otherwise to such Issuing Bank.

(c) Notwithstanding clauses (a) and (b) (unless the Administrative Agent requests that the provisions of clause (a) and (b) be followed) and any other provision in this Agreement or any other Loan Document providing for the delivery of any Approved Electronic Communication by any other means, the Borrowers shall deliver all Approved Electronic Communications to the Administrative Agent by properly transmitting such Approved Electronic Communications in an electronic/soft medium in a format acceptable to the Administrative Agent to xxxxxxxxxxxxxxx@xxxxxxxxx.xxx or such other electronic mail address (or similar means of electronic delivery) as the Administrative Agent may notify to the Borrowers. Nothing in this clause (c) shall prejudice the right of the Administrative Agent or any Lender Party to deliver any Approved Electronic Communication to the Borrowers in any manner authorized in this Agreement or to request that the Borrowers effect delivery in such manner.

Section 9.02 Posting of Approved Electronic Communications.

(a) Each of the Lender Parties and the Borrowers agree that the Administrative Agent may, but shall not be obligated to, make the Approved Electronic Communications available to the Lender Parties by posting such Approved Electronic Communications on IntraLinks™ or a substantially similar electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”).

(b) Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Closing Date, a dual firewall and a User ID/Password Authorization System) and the Approved Electronic Platform is secured through a single-user-per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lender Parties and the Borrowers acknowledges and agrees that the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. In consideration for the convenience and other benefits afforded by such distribution and for the other consideration provided hereunder, the receipt and sufficiency of which are hereby acknowledged, each of the Lender Parties and the Borrowers hereby approves distribution of the Approved Electronic Communications through the Approved Electronic Platform and understands and assumes the risks of such distribution.

(c) THE APPROVED ELECTRONIC PLATFORM AND THE APPROVED ELECTRONIC COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. NONE OF THE ADMINISTRATIVE AGENT NOR ANY OTHER MEMBER OF THE AGENT’S GROUP WARRANT THE ACCURACY, ADEQUACY OR COMPLETENESS OF THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC

PLATFORM AND EACH EXPRESSLY DISCLAIMS ANY LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM.

(d) Each of the Lender Parties and the Borrowers agree that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Approved Electronic Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally-applicable document retention procedures and policies.

Section 9.03 Waivers; Amendments.

(a) No failure or delay by the Administrative 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 Administrative Agent, the Issuing Banks 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 the Administrative Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrowers and the Required Lenders or by the Borrowers and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase or extend the Commitment of any Lender without the written consent of such Lender (provided that, for the avoidance of doubt, this clause (i) shall not be deemed to be applicable to an increase of a Borrower Sublimit), (ii) reduce 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) change any provision in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (v) change any of the provisions of this Section or the definition of “Required 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 the Administrative Agent or any Issuing Bank hereunder without the prior written consent of the Administrative Agent or such Issuing Bank, as the case may be. Except as provided herein, during such period as a Lender is a Defaulting Lender, to the fullest extent permitted by applicable law, such Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Commitment and the outstanding Loans or other extensions of credit of such Lender hereunder will not be taken into account in determining whether the Required Lenders or all of the

Lenders, as required, have approved any such amendment or waiver (and the definition of “Required Lenders” will automatically be deemed modified accordingly for the duration of such period); provided, that any such amendment or waiver referred to in clauses (i) through (v) or the proviso above or that would alter the terms of this proviso shall require the consent of such Defaulting Lender to the extent such Defaulting Lender is affected thereby.

Section 9.04 Expenses; Indemnity; Damage Waiver

(b) Each Borrower agrees, to the fullest extent permitted by law, to indemnify and hold harmless the Administrative Agent, the Issuing Banks, the Joint Lead Arrangers, each Lender (other than any Defaulting Lender) and each Related Party of any of the foregoing Persons (the “Indemnified Parties”) from and against any and all claims, damages, losses, liabilities, costs, penalties, fees and expenses (including reasonable fees and disbursements of counsel) of any kind or nature whatsoever for which any of them may become liable or which may be incurred by or asserted against any of the Indemnified Parties (other than claims and related damages, losses, liabilities, costs, penalties, fees and expenses made by one Lender (or its successors or assignees) against another Lender) arising out of, related to or in connection with (i) any Loan Document or any other document or instrument delivered in connection herewith, (ii) any violation by any Borrower or any Subsidiary thereof of any Environmental Law or any other law, rule, regulation or order, (iii) any Loan, any Letter of Credit or the use or proposed use of the proceeds of any Loan or Letter of Credit, (iv) any of the Aggregate Commitments, (v) any transaction in which any proceeds of any Letter of Credit or Loan are applied or (vi) any investigation, litigation or proceeding, whether or not any of the Indemnified Parties is a party thereto, related to or in connection with any of the foregoing or any Loan Document (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, PENALTY, FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNIFIED PARTY, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, PENALTY, FEE OR EXPENSE SOUGHT TO BE RECOVERED BY ANY INDEMNIFIED PARTY TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, PENALTY, FEE OR EXPENSE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY). IT IS THE INTENT OF THE PARTIES HERETO THAT EACH INDEMNIFIED PARTY SHALL, TO THE EXTENT PROVIDED IN THIS SECTION 9.04(b), BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE.

(c) To the extent that any Borrower fails to pay any amount required to be paid by it to the Administrative Agent or any Issuing Bank under paragraph (a) or (b) of this Section, each Lender

severally agrees to pay to the Administrative Agent or the applicable Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability, cost, penalty, fee or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or such Issuing Bank in its capacity as such.

(d) To the fullest extent permitted by applicable law, no party shall assert, and each party hereby waives, any claim against any other party or any Indemnified Party, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof; provided, however, that the foregoing limitation shall not be deemed to impair or affect the indemnification obligations of the Borrower under the Loan Documents. No Indemnified Party referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(e) All amounts due under this Section shall be payable not later than 30 days after written demand therefor, such demand to be in reasonable detail setting forth the basis for and method of calculation of such amounts.

Section 9.05 Successors and Assigns.

(a) Successors and Assigns Generally. 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, except that no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time 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 the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding 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 or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000 and shall be an integral multiple of $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, WPZ otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. 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 with respect to the Loans or the Commitment assigned and each assignment for any Borrower shall be made only if the same percentage of Commitments of the assigning Lender for each of the other Borrowers and the same percentage of LC Exposure of the assigning Lender are simultaneously assigned by the assigning Lender to the same Eligible Assignee pursuant to the same Assignment and Acceptance.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of WPZ (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments if such assignment is to a Person that is not a Lender with a Commitment, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

(C) the consent of the Issuing Banks (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding).

(iv) Assignment and Assumption. 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 (which fee may be waived by the Administrative Agent in its discretion), and the assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Borrower. No such assignment shall be made to any Borrower or any Borrower’s Affiliates or Subsidiaries.

(vi) No Assignment to Natural Persons or a Defaulting Lender. No such assignment shall be made to a natural person or a Defaulting Lender.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee

thereunder shall be a party to this Agreement 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 2.15, 2.17 and 9.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) Register. The Administrative Agent, acting solely 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, the Aggregate Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrowers, the Administrative Agent, the Issuing Banks 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 any Borrower and any Lender Party as to its own Commitments and amounts owing to it, at any reasonable time and from time to time upon reasonable prior notice. Upon its receipt of an executed Assignment and Acceptance, together with any Note subject to such assignment, and the payment of any processing and registration fee, the Administrative Agent shall (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the parties thereto.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, any Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or any Borrower or any Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender receives the documentation required under Section 2.17(f) from such participant (it being understood that the documentation required under Section 2.17(f) shall be delivered to the participating Lender), (iv) such Lender, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintains a register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”), provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant’s interest in any commitments, advances or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan or other obligation is in registered form for federal income Tax purposes or as otherwise required by law, and (v) the Borrowers, the Administrative Agent, the Lenders and the Issuing Banks 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 Section 9.03(b) that affects such Participant. Subject to paragraph (e) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 2.15, and 2.17 to the

same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.09 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 2.15 or 2.17 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 Borrowers’ 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 2.17 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.17(f) as though it were a Lender.

(f) Certain Pledges. 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 or any central bank having jurisdiction over such Lender; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 9.06 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 shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Aggregate Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.04 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Aggregate Commitments or the termination of this Agreement or any provision hereof.

Section 9.07 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 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. This Agreement shall become effective on the Closing Date, 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 or pdf shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 9.08 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 9.09 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender Party is hereby authorized at any time and from time to time, to the fullest extent permitted

by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender Party to or for the credit or the account of any Borrower or any Guarantor against any and all of the obligations of such Borrower or any Guarantor now or hereafter existing under this Agreement or any other Loan Document to such Lender Party, irrespective of whether or not such obligations of such Borrower or any Guarantor may be owed to a branch or office of such Lender Party different from the branch or office holding such deposit or obligated on such indebtedness, provided that demand has been made to the applicable Borrower for payment of such obligations. The rights of each Lender Party under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender Party may have. Each Lender Party agrees to notify the Borrowers and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

Section 9.10 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 arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State 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 respective 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 the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 9.11 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE

BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 9.12 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

Section 9.13 Confidentiality. Each of the Administrative Agent and the Lender Parties agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential) to the extent used in connection with the administration of this Agreement, (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) during the existence of an Event of Default, in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective party (or its managers, administrators, trustees, partners, directors, officers, employees, agents, advisors and other representatives) to any swap, derivative or other similar transaction under which payments are to be made by reference to any Borrower and its respective obligations, this Agreement or payments hereunder, (iii) any rating agency, (iv) the CUSIP Service Bureau or any similar organization or (v) any assignee in connection with any pledges permitted by Section 9.05(f), (g) with the consent of WPZ, or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent, any Lender Party or any of their respective Affiliates on a nonconfidential basis from a source other than a Borrower.

For purposes of this Section, “Information” means all information received from any Borrower or any of its Subsidiaries relating to the Borrowers or any of their respective Subsidiaries or any of their respective businesses, other than any such information that is available to the Administrative Agent or any Lender Party on a nonconfidential basis prior to disclosure by any Borrower or any of its Subsidiaries. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 9.14 Treatment of Information.

(a) Certain of the Lenders may enter into this Agreement and take or not take action hereunder or under the other Loan Documents on the basis of information that may contain material non-public information with respect to the Borrowers or their securities (such material non-public information, “Restricting Information”). Other Lenders may enter into this Agreement and take or not take action hereunder or under the other Loan Documents on the basis of information that does not contain Restricting Information. Each Lender Party acknowledges that United States federal and state securities laws prohibit any person from purchasing or selling securities on the basis of material, non-public information concerning such issuer of such securities or, subject to certain limited exceptions, from communicating such information to any other Person. Neither the Administrative Agent nor any of its Related Parties nor the Borrowers nor any of their Related Parties, shall, by making any Communications

(including Restricting Information) available to a Lender Party, by participating in any conversations or other interactions with a Lender Party or otherwise, make or be deemed to make any statement with regard to or otherwise warrant that any such information or Communication does or does not contain Restricting Information (except with respect to the Borrowers and their Related Parties, pursuant to Section 9.14(b)), nor shall the Administrative Agent or any of its Related Parties nor the Borrowers nor any of their Related Parties be responsible or liable in any way for any decision a Lender Party may make to limit or to not limit its access to Restricting Information. In particular, none of the Administrative Agent nor any of its Related Parties nor the Borrowers nor any of their Related Parties (i) shall have, and the Administrative Agent, on behalf of itself and each of its Related Parties, hereby disclaims, any duty to ascertain or inquire as to whether or not a Lender Party has or has not limited its access to Restricting Information, such Lender Party’s policies or procedures regarding the safeguarding of material, nonpublic information or such Lender Party’s compliance with applicable laws related thereto or (ii) shall have, or incur, any liability to any Borrower or Lender Party or any of their respective Related Parties arising out of or relating to the Administrative Agent or any of its Related Parties providing or not providing Restricting Information to any Lender Party.

(b) Each Borrower agrees that (i) all Communications it provides to the Administrative Agent intended for delivery to the Lender Parties whether by posting to the Approved Electronic Platform or otherwise shall be clearly and conspicuously marked “PUBLIC” if such Communications do not contain Restricting Information which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof, (ii) by marking Communications “PUBLIC,” the Borrowers shall be deemed to have authorized the Administrative Agent and the Lender Parties to treat such Communications as either publicly available information or not material information (although, in this latter case, such Communications may contain sensitive business information and, therefore, remain subject to the confidentiality undertakings of Section 9.14) with respect to the Borrowers or their securities for purposes of United States federal and state securities laws, (iii) all Communications marked “PUBLIC” may be delivered to all Lender Parties and may be made available through a portion of the Approved Electronic Platform designated “Public Side Information,” and (iv) the Administrative Agent shall be entitled to treat any Communications that are not marked “PUBLIC” as Restricting Information and may post such Communications to a portion of the Approved Electronic Platform not designated “Public Side Information.” Neither the Administrative Agent nor any of its Affiliates shall be responsible for any statement or other designation by any Borrower regarding whether a Communication contains or does not contain material non-public information with respect to the Borrowers or their securities nor shall the Administrative Agent or any of its Affiliates incur any liability to any Borrower, any Lender Party or any other Person for any action taken by the Administrative Agent or any of its Affiliates based upon such statement or designation, including any action as a result of which Restricting Information is provided to a Lender Party that may decide not to take access to Restricting Information. Nothing in this Section 9.14 shall modify or limit a Lender Party’s obligations under Section 9.13 with regard to Communications and the maintenance of the confidentiality of or other treatment of Information.

(c) Each Lender Party acknowledges that circumstances may arise that require it to refer to Communications that might contain Restricting Information. Accordingly, each Lender Party agrees that it will nominate at least one designee to receive Communications (including Restricting Information) on its behalf and identify such designee (including such designee’s contact information) on such Lender Party’s Administrative Questionnaire. Each Lender Party agrees to notify the Administrative Agent from time to time of such Lender Party’s designee’s e-mail address to which notice of the availability of Restricting Information may be sent by electronic transmission.

(d) Each Lender Party acknowledges that Communications delivered hereunder and under the other Loan Documents may contain Restricting Information and that such Communications are available to all Lender Parties generally. Each Lender Party that elects not to take access to Restricting

Information does so voluntarily and, by such election, acknowledges and agrees that the Administrative Agent and other Lender Parties may have access to Restricting Information that is not available to such electing Lender Party. None of the Administrative Agent nor any Lender Party with access to Restricting Information shall have any duty to disclose such Restricting Information to such electing Lender Party or to use such Restricting Information on behalf of such electing Lender Party, and shall not be liable for the failure to so disclose or use, such Restricting Information.

(e) The provisions of the foregoing clauses of this Section 9.14 are designed to assist the Administrative Agent, the Lender Parties and the Borrower, in complying with their respective contractual obligations and applicable law in circumstances where certain Lender Parties express a desire not to receive Restricting Information notwithstanding that certain Communications hereunder or under the other Loan Documents or other information provided to the Lender Parties hereunder or thereunder may contain Restricting Information. Neither the Administrative Agent nor any of its Related Parties warrants or makes any other statement with respect to the adequacy of such provisions to achieve such purpose nor does the Administrative Agent or any of its Related Parties warrant or make any other statement to the effect that any Borrower’s or Lender Party’s adherence to such provisions will be sufficient to ensure compliance by any Borrower or Lender Party with its contractual obligations or its duties under applicable law in respect of Restricting Information and each of the Lender Parties and each Borrower assumes the risks associated therewith.

Section 9.15 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together (to the extent lawful) with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

Section 9.16 No Waiver; Remedies. No failure on the part of any Lender Party or the Administrative Agent to exercise, and no delay in exercising, any right under this Agreement or any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies provided in this Agreement are cumulative and not exclusive of any remedies provided by law.

Section 9.17 Liability of General Partner. It is hereby understood and agreed that the General Partner shall have no personal liability, as general partner or otherwise, for the payment of any amount owing or to be owing hereunder or under the other Loan Documents. Notwithstanding the foregoing, nothing in this Section 9.17 shall be construed to modify or supersede any obligation of the General Partner to restore any negative balance in its capital account (maintained by WPZ pursuant to the Partnership Agreement) upon liquidation of its interest in the Borrower.

Section 9.18 USA Patriot Act Notice. Each Lender Party and Administrative Agent (for itself and not on behalf of any Lender) hereby notifies each Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2003)) (the “Act”), it is required to obtain, verify and record information that identifies each Borrower, which information includes the name and address of such Borrower and other information that will allow such Lender Party or the

Administrative Agent, as applicable, to identify each Borrower in accordance with the Act. Each Borrower shall, following a request by the Administrative Agent or any Lender Party, provide all documentation and other information that the Administrative Agent or such Lender Party reasonably requests in order to comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the Act.

Section 9.19 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby, each Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (a) the credit facility provided for hereunder and any related arranging or other services in connection therewith (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document) are an arm’s-length commercial transaction between the Borrowers, on the one hand, and the Administrative Agent and the Lenders, on the other hand, and each Borrower is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents (including any amendment, waiver or other modification hereof or thereof); (b) in connection with the process leading to such transaction, the Administrative Agent and the Lenders are and have been acting solely as principals and are not the financial advisors, agents or fiduciaries, for any Borrower or any of their respective Affiliates, stockholders, creditors or employees or any other Person; (c) the Administrative Agent and the Lenders have not assumed or will assume an advisory, agency or fiduciary responsibility in favor of any Borrower with respect to any of the transactions contemplated hereby or the process leading thereto, including with respect to any amendment, waiver or other modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent or any Lender advised or is currently advising any Borrower or any of their respective Affiliates on other matters) and the Administrative Agent and the Lenders have no obligation to any Borrower or any of their respective Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; (d) the Administrative Agent, the Lenders and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrowers and their respective Affiliates, and the Administrative Agent and the Lenders have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (e) the Administrative Agent and the Lenders have not provided and will not provide any legal, accounting, regulatory or tax advice with respect to any of the transactions contemplated hereby (including any amendment, waiver or other modification hereof or of any other Loan Document) and each of the Borrowers has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate. Each of the Borrowers hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Administrative Agent or the Lenders with respect to any breach or alleged breach of agency (other than against the Administrative Agent acting in its administrative capacity) or fiduciary duty; provided, however that it being understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 9.20 GP Buy-in. Notwithstanding any term or provision herein or in any other Loan Document, the parties hereto agree that any GP Buy-in and any transaction related thereto is expressly permitted under this Agreement and each other Loan Document without any further action, waiver, consent or agreement by the Administrative Agent, the Arrangers, any other agent or any Lender from time to time party hereto. As used herein, “GP Buy-in” refers to any sale, lease, transfer or disposition by Xxxxxxxx of its Equity Interests in the General Partner to WPZ.

Section 9.21 Amendment and Restatement. This Agreement represents an amendment and restatement of the Existing Credit Agreement. Any indebtedness under the Existing Credit Agreement continues, without duplication, under this Agreement, and the execution of this Agreement does not indicate a payment, satisfaction, novation or discharge thereof.
