Each indemnified party hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (such claims for indemnity involving third party claims being collectively referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give prompt notice thereof in writing to the indemnifying party, together with a detailed statement of such information respecting any of the foregoing as it shall have and all supporting evidence, including any Damages already incurred and its detailed estimate of any Damages to be incurred in the future. Such notice shall include a formal demand for indemnification under this Agreement.

If the indemnified party knowingly failed to notify the indemnifying party thereof in accordance with the provisions of this Agreement in sufficient time to permit the indemnifying party or its counsel to defend against an Indemnity Claim and to make a timely response thereto, the indemnifying party’s indemnity obligation relating to such Indemnity Claim shall be limited to the extent that such failure has actually prejudiced or damaged the indemnifying party with respect to that Indemnity Claim.

9.6

Right to Contest and Defend.

The indemnifying party shall be entitled, at its cost and expense, to contest and defend by all appropriate legal proceedings any Indemnity Claim for which it is called upon to indemnify the indemnified party under the provisions of this Agreement; provided, that notice of the intention to so contest shall be delivered by the indemnifying party to the indemnified party within twenty (20) days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted by reputable counsel employed by the indemnifying party and not reasonably objected to by the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense.

The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the indemnifying party will not have the authority to subject the indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense or injunctive relief. If the indemnifying party does not elect to contest any such Indemnity Claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party assumes the defense of an Indemnity Claim, the indemnified party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Indemnity Claim, which releases the indemnified party completely in connection

with such Indemnity Claim and which would not otherwise adversely affect the indemnified party as reasonably determined by the indemnified party.

Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages.

9.7

Cooperation.

If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the Indemnity Claim, or any cross-complaint against any person, and the indemnifying party will reimburse the indemnified party for any expenses incurred by it in so cooperating. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim.

9.8

Right to Participate.

The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in, conferences with all Persons, including Governmental Authorities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such Persons.

9.9

Payment of Damages.

The indemnification required hereunder shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within ten (10) days as and when reasonably specific bills are received or loss, liability, claim, damage or expense is incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount shall be reduced by (a) all insurance proceeds and any indemnification reimbursement proceeds received from third parties credited to or received by the other party related to the Damages and (b) any Tax benefit to be realized by the indemnified party related to the Damages.

9.10

Limitations on Indemnification.

(a)

To the extent that the Partnership Indemnified Parties are entitled to indemnification for Damages pursuant to Section 9.1(i) and Section 9.1(ii), the Contributing Parties shall be liable only for those Damages that in the aggregate are in excess of 1.0% of the

Consideration (the “Deductible Amount”), and then only to the extent of any such excess. In no event shall the Contributing Parties’ aggregate liability to the Partnership Indemnified Parties under Section 9.1(i) exceed 15% of the Consideration (the “Ceiling Amount”). Notwithstanding the foregoing, (i) the Deductible Amount shall not apply to inaccuracies, violations or breaches of representations and warranties contained in Section 3.1, Section 3.2, Section 3.4, Section 3.14 and Section 3.16 and (ii) the Ceiling Amount shall not apply to inaccuracies, violations or breaches of representations and warranties contained in Section 3.2, Section 3.3, Section 3.4, and Section 3.16 provided, the Contributing Parties’ aggregate liability for a breach of Section 3.2, Section 3.3, Section 3.4 and Section 3.16 shall not exceed the amount of the Consideration.

(b)

To the extent the Contributing Indemnified Parties are entitled to indemnification for Damages pursuant to Section 9.2(i), the Partnership Parties shall be liable only for those Damages which exceed, in the aggregate, the Deductible Amount, and then only to the extent of any such excess. In no event shall the Partnership Parties’ aggregate liability to the Contributing Indemnified Parties under Section 9.2(i) exceed the Ceiling Amount. Notwithstanding the foregoing, (i) the Deductible Amount shall not apply to inaccuracies, violations or breaches of representations and warranties contained in Section 4.1, Section 4.2 and Section 4.4 and (ii) the Ceiling Amount shall not apply to inaccuracies, violations or breaches of representations and warranties contained in Section 4.2, Section 4.3 and Section 4.4 provided, the Partnership Parties’ aggregate liability for a breach of Section 4.2, Section 4.3 and Section 4.4 shall not exceed the amount of the Consideration.

Additionally, neither the Partnership Parties, on the one hand, nor the Contributing Parties, on the other hand, will be liable as an indemnitor under this Agreement for any consequential, incidental, special, indirect or exemplary damages suffered or incurred by the indemnified party or parties.

(d)

The Parties agree that El Paso is solely liable with respect to any indemnification or payment obligation pursuant to this Article 9 relating to Damages suffered or incurred by the Partnership Indemnified Parties associated with any of the SNG Entities’ assets, businesses or operations. The Parties agree that the Contributing Parties are jointly and severally liable for any indemnification or payment obligation pursuant to this Article 9 of the Contributing Parties relating to any remaining Damages suffered or incurred by the Partnership Indemnified Parties that are not directly attributable to any SNG Entity or their respective assets, businesses or operations.

If any provision of the Agreement is rendered or declared illegal or unenforceable by reason of any existing or subsequently enacted legislation or by decree of a court of last resort, the Partnership Parties and the Contributing Parties shall promptly meet and negotiate substitute provisions for those rendered or declared illegal or unenforceable, but all of the remaining provisions of this Agreement shall remain in full force and effect.

Schedule 3.8

Litigation; Laws and Regulations

A. Litigation

The following lawsuits are pending or have been threatened:

MMS Royalty Claim. Potential reimbursement obligation owed to Total E&P USA associated with five take-or-pay contract settlements reached in the late 1980s with Total’s predecessor.

Louisiana Crawfish Producers Association West v. Amerada Hess, et al. Louisiana State District Court.

Lloyds Litigation. Alabama state court action. SNG is the plaintiff in this case.

Other Litigation. Southern LNG Company, L.L.C. (“SLNG”), Elba Express Company, L.L.C. (“EEC”) and Southern Natural Gas Company (“SNG”) are involved in other litigation that arise in the ordinary course of business, including without limitation less material commercial disputes, various condemnation lawsuits associated with expansion projects, property tax cases, escheat matters, landowner disputes and collection matters.

B. Ad Valorem Tax Disputes

SLNG currently has ad valorem tax disputes relating to three issues: 1) personal property valuation for the period 2003-2007; 2) tax on the gas in inventory; and 3) centralized assessment of SLNG by the Georgia Department of Revenue. SLNG paid over $9M in taxes on personal property to Chatham County for 2003-2007 based on original and agreed valuation. Recent retroactive audits, which are allowed by statute, increased the property values and SLNG has recently been assessed an additional $3.5M. Chatham County has never sent tax bills based on the higher values; therefore, the $3.5 million is not currently due and has not been paid. In addition SLNG has disputed approximately $1 million of ad valorem taxes in 2008, arguing that valuation should be established through a unit value rather than a cost approach.

SLNG has filed protests challenging the new assessment and has entered into arbitration. These protests are pending determination in an optional arbitration program under the jurisdiction of the superior court, with a referee administering the arbitration. At the arbitration held on 1/25 and 1/26/10, the issue for decision for each year was the fair market value of the taxable personal property owned by the taxpayer in Chatham County. The fundamental difference in the party’s positions was the approach to the valuation of the personal property for ad valorem tax purposes. Southern LNG’s position was that the correct way to value FERC regulated property is by the unit value approach. On the other hand, it appears the County has valued the personal property using a basic cost approach with no economic obsolescence. At the hearing, the Board of Tax Assessors had the burden of proving their opinions of value by a preponderance of the evidence. On March 18, 2010, the panel rendered its unanimous awards in each of the five tax

years. It is estimated that these awards will result in additional tax of $146,300 total for all five years. The county had sought increased values that would have resulted in additional tax of $3,163,175. This ruling has been appealed to the district court for a trial de novo.

C. FERC Regulatory Proceedings — The following proceedings are pending before the Federal Energy Regulatory Commission (“FERC”) or on appeal from the FERC:

SLNG, EEC, and Southern Natural Gas Company, 120 FERC ¶61,258 (2007), Order Issuing Certificates, Authorizing Abandonments, Granting Authorization and Denying Rehearing, requiring compliance with certain environmental conditions listed in Appendix B thereto.

SLNG, Docket No. CP10-477. (Truck Loading Facilities). Application to abandon certain facilities and to reactivate, expand, operate and lease truck loading facilities.

SLNG, Docket No. RP10-829. (Gas Quality). Tariff filing to implement new gas quality and interchangeability standards.

MOPS Abandonment (CP10-82). Proposal to abandon non-contiguous facilities that are jointly owned by Northern Natural, SNG and FGT. Application has been protested by producers in the area that oppose the abandonment.

EC23 Abandonment (CP11-14). Proposal to abandon facilities that are jointly owned by SNG and Columbia Transmission Company, and transportation service through such facilities.

SLNG, EEC and SNG are regulated by the FERC and are involved in other regulatory proceedings that arise in the ordinary course of business, including without limitation less material tariff filings, smaller expansion projects, reporting and accounting requirements, and audits. The recourse rates and negotiate rates that SLNG and EEC may charge are subject to the jurisdiction of the FERC. In addition, the rates that SNG charges are subject to the jurisdiction of the FERC. Under its current settlement agreement in Docket No. RP09-427, SNG is permitted to file a rate case to be effective no earlier than September 1, 2012 and is required to file a rate case to be effective no later than September 1, 2013.

D. PHMSA Proceedings

PHMSA Audit and NOPV. Pipeline and Hazardous Materials Safety Administration (“PHMSA”) issued a Notice of Probable Violation, Proposed Civil Penalty and Proposed Compliance Order (“Notice”) to El Paso Pipeline Group.

PHMSA CAOs — PHMSA has issued Corrective Action Orders (CAOs) directing SNG to take certain corrective actions with respect to failures on: 1) 24-inch North Main Loop line near Heflin, AL, 2) 24-inch North Main Line near the Louisville, MS Compressor Station, and 3) 20-inch line near Toca, LA.

Schedule 3.11

Environmental Matters

A. Remediation Projects — SNG

General Background. SNG is subject to federal, state and local laws and regulations governing environmental quality and pollution control. These laws and regulations require us to remove or remedy the effect on the environment of the disposal or release of specified substances at current and former operating sites. At September 30, 2010, SNG had accrued less than $1 million for expected remediation costs and associated onsite, offsite and groundwater technical studies.

CERCLA Restitution Notice (EPA). SNG was named as potentially responsible party (PRP) under a previous settlement entered into with the EPA in 1999 relating to the Port Refinery Superfund Site in Rye Brook, New York. EPA has stated that it is seeking a total of $7 million in reimbursement from a number of parties. Based on the small amount of material sent by SNG to this site and the precedence of the prior settlement, SNG believes that EPA will only be seeking a de minimis settlement from SNG.

Sandy Hook Site. Remediation activities are ongoing along pipeline site formerly owned by SNG.

Iron Bowl Site. Conducting groundwater monitoring in response to historical hydrocarbon release.

B. Compliance Matters — SNG

Notice of Violation, Albany, Georgia Compressor Station. On October 22, 2010, the Georgia Environmental Protection Division (GEPD) issued a notice of violation (NoV) to SNG concerning turbine no. 3 at SNG’s Albany, Georgia compressor station. The NoV concerns the control set point for the combustor outlet temperature for that turbine and whether such set point was set correctly based on previously-conducted testing and related reporting issues. GEPD has provided a deadline of late November for SNG to respond. The NoV does not state what amount of, if any, penalty may be sought.

We expect to make capital expenditures for environmental matters of approximately $2 million in the aggregate for the remainder of 2010 through 2014, primarily, to be expended from 2010 to 2013 associated with the impact of the EPA rule related to emissions of hazardous air pollutants from reciprocating internal combustion engines which was finalized in August 2010. Our engines that are subject to the regulations have to be in compliance by October 2013.

C. Compliance Matters — SLNG

Notice of Violation, Train III Vaporizers. Pursuant to the terms of our air permits for the SLNG’s Train III vaporizers, we are required to submit reports to the GEPD with regard to compliance

with such permits. We have conducted an initial performance test and a Relative Accuracy Test Audit (RATA) on the Predictive Emissions Monitoring System (PEMS) for the Train III vaporizers and submitted reports to GEPD concerning those actions and we are currently in discussions with GEPD concerning these tests and reports. On November 2, 2010, GEPD issued a NoV to SLNG alleging violations of SLNG’s air permit related to these issues. The NoV does not specify if any penalty will be sought. SLNG’s response to the NoV is due by December 8, 2010.

1. AUTHORIZATION OF NOTES.

1.1 Description of Notes to be Initially Issued.

          The Issuer has authorized the issue and sale of $[718],000,000 aggregate principal amount of its Floating Rate Senior Notes, due 360 days from the date of issuance, 2011 (the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 13 of this Agreement). The Notes shall be substantially in the form set out in Exhibit 1.1, with such changes therefrom, if any, as may be approved by the Purchasers and the Issuer. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

1.2 Interest Rate.

          (a) The Notes shall bear interest (computed on the basis of a 360-day year and actual days elapsed) (i) on the unpaid principal thereof from the date of issuance at the rate stated in clause (a) of the first paragraph of the Note payable quarterly in arrears on the last day of March, June, September and December in each year commencing on [                    ], 20[__], until such principal sum shall have become due and payable (whether at maturity, upon prepayment or otherwise) and (ii) to the extent permitted by applicable law, on any overdue principal, any

overdue installment of interest and any overdue payment of LIBOR Breakage Amount from the due date thereof (whether by acceleration or otherwise) at the applicable Default Rate until paid.

          (b) Whenever the Applicable Floating Rate consists of the Adjusted LIBOR Rate, the Adjusted LIBOR Rate shall be determined by the Issuer, and notice thereof shall be given to the holders of the Notes, together with such information as the holders of the Notes may reasonably request for verification (including in all events, a facsimile transmission of the relevant screen and calculations), on the second Business Day preceding each Interest Period. In the event that the Required Holders do not concur with such determination by the Issuer, as evidenced by notice to the Issuer by such Required Holders within ten (10) Business Days after receipt by such holders of the notice delivered by the Issuer pursuant to the previous sentence, the determination of the Adjusted LIBOR Rate shall be made by the Required Holders in accordance with the provisions of this Agreement and shall be conclusive and binding absent manifest error.

1.3 Guaranties; Release.

     (a) Subsidiary Guaranty. The payment by the Issuer of all amounts due on or in respect of the Notes and the performance by the Issuer of its obligations under this Agreement will be guaranteed by each Subsidiary Guarantor executing and delivering a subsidiary guaranty in substantially the form of the attached Exhibit 1.3(a), as it may be amended or supplemented from time to time (a “Subsidiary Guaranty”), after the date of this Agreement in accordance with Section 9.7.

     (b) Parent Guaranty. The payment by the Issuer of all amounts due on or in respect of the Notes and the performance by the Issuer of its obligations under this Agreement will be guaranteed by the MLP pursuant to a parent guaranty in substantially the form of the attached Exhibit 1.3(b), as it may be amended or supplemented from time to time (the “Parent Guaranty”).

     (c) Release of Guaranties. Each holder of a Note acknowledges and agrees that a Subsidiary Guarantor shall be fully released and discharged from its Subsidiary Guaranty and each holder of a Note fully releases and discharges such Subsidiary Guarantor from its Subsidiary Guaranty immediately and without any further act, upon such Subsidiary being released and discharged as a guarantor under and in respect of the Credit Agreement; provided that (i) no Default or Event of Default exists or will exist immediately following such release and discharge; (ii) if any fee or other consideration is paid or given to any holder of Indebtedness under the Credit Agreement in connection with such release, other than the repayment of all or a portion of such Indebtedness under the Credit Agreement, each holder of a Note receives equivalent consideration on a pro rata basis; and (iii) at the time of such release and discharge, the Issuer delivers to each holder of a Note a certificate of a Responsible Officer certifying (a) that such Subsidiary Guarantor has been or is being released and discharged as a guarantor under and in respect of the Credit Agreement and (b) as to the matters set forth in clauses (i) and (ii).

2. SALE AND PURCHASE OF NOTES.

At the Closing the Issuer will deliver to each Purchaser the Notes to be purchased by it in the form of a single Note (or such greater number of Notes in denominations of at least $100,000 as such Purchaser may request) dated the date of this Agreement and registered in such Purchaser’s name (or in the name of such Purchaser’s nominee), against delivery by such Purchaser to the Issuer or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Issuer to account number [100-8944 at Mellon Bank, Pittsburgh, Pennsylvania, ABA No. 043 000 261], FAO: El Paso Pipeline Partners Operating Company, L.L.C.

disclosed on such financial statements or otherwise disclosed in the Information Document, other than any such liabilities arising in the ordinary course of business subsequent to the date of such financial statements.

5.6 Compliance with Laws, Other Instruments, etc.

          (a) The execution, delivery and performance by the Issuer of this Agreement and the Notes will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Issuer or any of its Subsidiaries under, any indenture, mortgage, deed of trust, loan, note purchase or credit agreement, lease, Organization Document, or any other Material agreement or instrument to which the Issuer or any such Subsidiary is bound or by which the Issuer or any such Subsidiary or any of their respective properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Issuer or any such Subsidiary or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority, including the USA Patriot Act, applicable to the Issuer or any such Subsidiary.

          (b) The execution, delivery and performance by the MLP of the Parent Guaranty and this Agreement will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the MLP under, any agreement or Organization Document to which the MLP is bound or by which the MLP or any of its properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the MLP or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the MLP.

5.8 Litigation; Observance of Agreements, Statutes and Orders.

     (a) There are no actions, suits or proceedings pending or, to the knowledge of the MLP or the Issuer, threatened against or affecting the MLP, the Issuer or any Subsidiary thereof or any property of the MLP, the Issuer or any Subsidiary thereof in any court or before any arbitrator of any kind or before or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

     (b) None of the MLP, the Issuer or any Subsidiary thereof is in default under any term of any agreement or instrument to which it is a party or by which it is bound, or any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in violation of any applicable law, ordinance, rule or regulation (including Environmental Laws and the USA Patriot Act) of any Governmental Authority, which

default or violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

5.9 Taxes.

          The MLP, the Issuer and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the failure to file or pay which, as applicable, would have a Material Adverse Effect or (ii) the amount, applicability or validity of which is currently being diligently contested in good faith by appropriate proceedings and with respect to which the MLP, the Issuer or such Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The Issuer knows of no basis for any other tax or assessment that could reasonably be expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the MLP, the Issuer and its Subsidiaries in respect of Federal, state or other taxes for all fiscal periods are adequate.

5.10 Title to Property; Leases.

          The MLP, the Issuer and its Subsidiaries have good and sufficient title to their respective properties except for such defects of title as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, in each case free and clear of Liens prohibited by this Agreement. All leases of the MLP, the Issuer or any Subsidiary are valid and subsisting and are in full force and effect in all material respects, except leases the failure of which to maintain, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

5.11 Licenses, Permits, etc.

     (a) The MLP, the Issuer and its Subsidiaries own or possess all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, except to the extent that the failure to own or possess the same could not reasonably be expected to have a Material Adverse Effect, and there are no known conflicts of the same with the rights of others that could reasonably be expected to have a Material Adverse Effect.

     (b) To the best knowledge of the MLP and the Issuer, no product of the MLP, the Issuer or any Subsidiary of the Issuer infringes any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person, which infringement could reasonably be expected to have a Material Adverse Effect.

     (c) To the best knowledge of the MLP and the Issuer, there is no violation by any Person of any right of the MLP, the Issuer or any Subsidiary of the Issuer with respect to any patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by the MLP, the Issuer or any Subsidiary of the Issuer, the violation of which could reasonably be expected to have a Material Adverse Effect.

5.12 Compliance with ERISA.

     (a) No Termination Event has occurred or is reasonably expected to occur with respect to any Plan which, with the giving of notice or lapse of time, or both, would constitute an Event of Default under Section 11(h).

     (b) The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term “benefit liabilities” has the meaning specified in section 4001 of ERISA and the terms “current value” and “present value” have the meaning specified in section 3 of ERISA.

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

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

     (e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(e)(1)(A)(D) of the Code.

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

     (g) Neither the MLP nor any ERISA Affiliate has received any notification that any Multiemployer Plan is in reorganization, insolvent or has been terminated, within the meaning of Title IV of ERISA, and no Multiemployer Plan is reasonably expected to be in reorganization, to be insolvent or to be terminated within the meaning of Title IV of ERISA the effect of which reorganization, insolvency or termination would be the occurrence of an Event of Default under Section 11(h).

5.13 Private Offering by the Issuer.

          Neither the Issuer nor anyone acting on the Issuer’s behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers, each of which has been offered the Notes at a private sale for investment. Neither the Issuer nor anyone acting on the Issuer’s behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act or to the registration requirements of any securities or blue sky laws of any applicable jurisdiction.

5.14 Use of Proceeds; Margin Regulations.

          The Issuer will apply the proceeds of the sale of the Notes in the manner described in the Information Document.

Margin stock does not constitute more than 1% of the value of the consolidated assets of the Issuer and the Issuer’s Subsidiaries and the Issuer has no present intention that margin stock will constitute more than 1% of the value of such assets.

Rated Securities and the MLP or the Issuer fails to obtain (whether by failing to seek a rating or otherwise) either a rating of the Notes or any other unsecured and unsubordinated Indebtedness of the MLP or the Issuer having a remaining maturity of five (5) years or more (and which does not have the benefit of a guaranty from any Person other than any such Person that at such time also guarantees the obligations of the Issuer under this Agreement and the Notes) from a Rating Agency of at least Investment Grade (a “Negative Rating Event”), in each case after giving pro forma effect to the transaction giving rise to such Change of Control (such Change of Control and the related Rating Downgrade or, as the case may be, Negative Rating Event, together (but not individually) constituting the Change of Control Prepayment Event).

     (b) Promptly upon becoming aware that a Change of Control has occurred, and in any event no later than fifteen (15) days after becoming aware of the Change of Control, the Issuer shall give written notice of such fact to all holders of the Notes. Promptly upon becoming aware that a Change of Control Prepayment Event has occurred, and not later than thirty (30) days after becoming aware of the Change of Control Prepayment Event, the Issuer shall give written notice (the “Issuer Notice”) of such fact to all holders of the Notes.

     (c) A holder of a Note may accept the offer to prepay made pursuant to this Section 8.3 by causing a notice of such acceptance to be delivered to the Issuer on or before the Proposed Prepayment Date. A failure by a holder of a Note to respond to an offer to prepay made pursuant to this Section 8.3 or to accept an offer by the Issuer to prepay all of the Notes held by such holder prior to the Proposed Prepayment Date shall be deemed to constitute rejection of such offer by such holder.

     (d) On any Proposed Prepayment Date, the entire unpaid principal amount of the Notes held by each holder of the Notes which has accepted such prepayment offer, together with interest accrued thereon to such date, but including any LIBOR Breakage Amount with respect to any Notes being prepaid on a day other than a Floating Interest Payment Date, shall become due and payable.

From and after such date, unless the Issuer shall fail to pay such principal amount when so due and payable, together with the LIBOR Breakage Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full, after such payment and upon the written request of the Issuer, shall be surrendered to the Issuer and canceled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

8.6 Purchase of Notes.

          The Issuer will not and will not permit the MLP, the Issuer or any Subsidiary to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to a written offer to purchase any outstanding Notes made by the Issuer or an Affiliate pro rata to the holders of Notes or any series thereof upon the same terms and conditions.

          If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

12.3 Rescission.
