(b) Each Subsidiary Guarantor, and by its acceptance of this Agreement and the rights hereunder or benefits hereof the Collateral Agent and each other Secured Party, hereby agrees and confirms that (i) it is the intention of all such Persons that this Agreement and the obligations of such Subsidiary Guarantor under this Article 2 not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law (as defined below), the Uniform Fraudulent Conveyance Act (as adopted by any applicable state), the Uniform Fraudulent Transfer Act (as adopted by any applicable state) or any similar foreign, federal or state law to the extent applicable to this Agreement and the obligations of such Subsidiary Guarantor under this Article 2 and (ii) the aggregate liability of each Subsidiary Guarantor under this Article 2 and under the other Securing Documents at any time (but after giving effect to the right of contribution described in Section 2.02) shall not exceed the maximum amount (as to any Subsidiary Guarantor, its “Maximum Liability”) that will result in the aggregate obligations of such Subsidiary Guarantor under this Article 2 and under the Security Documents not constituting a fraudulent transfer or conveyance under Bankruptcy Law or any of the other aforementioned acts and laws. For purposes hereof, “Bankruptcy Law” means the Bankruptcy Code, or any similar foreign, federal or state law for the relief of debtors.

(c) Each Subsidiary Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of such Subsidiary Guarantor hereunder without impairing the guarantee contained in this Article 2 or affecting the rights and remedies of the Collateral Agent or any Secured Party hereunder.

(d) The guarantee contained in this Article 2 shall remain in full force and effect until the later (the “Guarantee Release Date”) of (i) the Final Payment Date and (ii) the date (the “Repayment Date”) on which all payment obligations of each Subsidiary Guarantor in respect of the Guaranteed Obligations and the payment obligations under the guarantee contained in this Article 2 shall have been satisfied by indefeasible payment in full in cash.

(e) No payment or payments made by the Company, any Pipeline Company Borrower, any of the Subsidiary Guarantors, any other guarantor or any other Person, or received or collected by the Collateral Agent or any Secured Party from the Company, any Pipeline Company Borrower, any of the Subsidiary Guarantors, any other guarantor or any other Person, by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of Guaranteed Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Subsidiary Guarantor under this Article 2 which shall, notwithstanding any such payment or payments (other than any payment or payments made by such Subsidiary Guarantor in respect of the Guaranteed Obligations or any payment received or collected from such Subsidiary Guarantor in respect of Guaranteed Obligations), remain liable for the Guaranteed Obligations up to the Maximum Liability of such Subsidiary Guarantor under this Article 2 until the Guarantee Release Date.

Section 2.02 . Right of Contribution. Each Subsidiary Guarantor hereby agrees that to the extent that a Subsidiary Guarantor shall have paid or be obligated to pay more than its proportionate share of any payment made hereunder, such Subsidiary Guarantor shall be entitled to contribution from and against any other Subsidiary Guarantor that has not paid its proportionate share of such payment. Each Subsidiary Guarantor’s right of contribution shall be subject to the terms and conditions of Section 2.03. The provisions of this Section 2.02 shall in no respect limit the obligations and liabilities of any Subsidiary Guarantor to the Collateral Agent and the Secured Parties, and each Subsidiary Guarantor shall remain liable to the Collateral Agent and the Secured Parties for the full amount guaranteed by such Subsidiary Guarantor hereunder.

Section 2.03 . No Subrogation. Notwithstanding any payment made by any Subsidiary Guarantor hereunder or any set-off or application of funds of any Subsidiary Guarantor by the Collateral Agent or any Secured Party, no Subsidiary Guarantor shall be entitled to be subrogated to any of the rights of the Collateral Agent or any Secured Party against the Company or any other Subsidiary Guarantor or any collateral security or guarantee or right of offset held by the Collateral Agent or any Secured Party for the payment of Guaranteed Obligations, nor shall any Subsidiary Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor hereunder, until the Guarantee Release Date. If any amount shall be paid to any Subsidiary Guarantor on account of such subrogation rights prior to the Guarantee Release Date, such amount shall be held by such Subsidiary Guarantor in trust for the Collateral Agent and the Secured Parties, segregated from other funds of such Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary Guarantor, be turned over to the Collateral Agent in the exact form received by such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the Collateral Agent, if required), to be applied against Guaranteed Obligations, whether matured or unmatured, in accordance with the terms and provisions of the Credit Agreement and Security Agreement.

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

Section 2.05 . Guarantee Absolute and Unconditional. Each Subsidiary Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Guaranteed Obligations and notice of or proof of reliance by the Collateral Agent or any other Secured Party upon the guarantee contained in this Article 2 or acceptance of the guarantee contained in this Article 2. Each Subsidiary Guarantor waives diligence, presentment, protest, demand for payment, notice of intent to accelerate, notice of acceleration and notice of default or nonpayment to or upon the Company, any Pipeline Company Borrower or any of the Subsidiary Guarantors with respect to Guaranteed Obligations. Each Subsidiary Guarantor understands and agrees that the guarantee contained in this Article 2 shall be construed as a continuing, absolute, irrevocable and unconditional guarantee of payment without regard to (a) the validity or enforceability or perfection of the Credit Agreement or any other Financing Document, any of the Guaranteed Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Collateral Agent or any Secured Party, (b) any defense, set-off or counterclaim whatsoever (other than a defense of payment or performance) which may at any time be available to or be asserted by the Company or any other Person against the Collateral Agent or any other Secured Party, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Company or such Subsidiary Guarantor or any other Credit Party), other than payment or performance, which constitutes, or might be construed to constitute, an equitable or legal discharge of the Company, any Pipeline Company Borrower or any other Subsidiary Guarantor for any of its respective portion of the Guaranteed Obligations or of such Subsidiary Guarantor under the guarantee contained in this Article 2, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Subsidiary Guarantor, the Collateral Agent may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against the Company, any Pipeline Company Borrower, any other Subsidiary Guarantor or any other Person or against any collateral security or guarantee for the Guaranteed Obligations or any right of offset with respect thereto, and any failure by the Collateral Agent to make any such demand, to pursue such other rights or remedies or to collect any payments from the Company, any Pipeline Company Borrower, any other Subsidiary Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Company, any Pipeline Company Borrower, any other Subsidiary Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve such Subsidiary Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Collateral Agent against such Subsidiary Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

Section 2.06 . Reinstatement. The guarantee contained in this Article 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by the Collateral Agent or any Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, any Pipeline Company Borrower, or any Subsidiary Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company, any Pipeline Company Borrower, or any Subsidiary Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

Section 2.07 . Payments. Each Subsidiary Guarantor hereby agrees that payments required to be made by it hereunder will be paid to the Collateral Agent without set-off or counterclaim in dollars at the office of the Collateral Agent identified in Section 9.04 of the Security Agreement.

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

Section 3.08 . Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.
