Table of Contents

9.5 Demands.

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.

Table of Contents

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.

Table of Contents

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.

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”).

(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.

This Agreement and the other Ancillary Documents, read as a whole, set forth the Parties’ rights, responsibilities and liabilities with respect to the transactions contemplated by this Agreement.

Schedule 3.11

Environmental Matters

A. Remediation Projects - SNG

General Background. SNG and CIG are 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 March 31, 2011, SNG had no accrual for our environmental matters, and CIG had approximately $10 million for expected remediation costs and associated onsite, offsite and groundwater technical studies and for related environmental legal costs; however, we estimate that our exposure could be as high as $33 million. The accrual includes $6 million for environmental contingencies related to properties we previously owned.

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.

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

Iron Bowl Site. We received a No Further Action letter from the State of Alabama. The monitor wells have been plugged and abandoned. We are working with the landowner on deed restrictions requested by the State.

CIG PCB Soils. Based on further investigation, it was determined additional soil remediation will be required at ten stations. The estimated cost for the work increased the environmental reserve by $1.2 million bringing the total to $2.2 million.

Table Rock. Remediation activities are ongoing at the Table Rock Processing Plant formerly owned by CIG, along with an adjacent site that is owned by CIG.

Bivins Compressor Station. Remediation activities are ongoing at the Bivins Compressor Station formerly owned by CIG.

Sanford Site. Further investigation is being performed to determine the extent of the free phase hydrocarbons and impacted groundwater in the central portion of the site owned by CIG.

Mocane Facilities. Remediation by monitoring natural attenuation is ongoing at the compressor station site owned by CIG, along with a neighboring site sold by CIG to a third party.

Table of Contents

Panhandle Gathering System. Remediation activities are ongoing with regard to various sites along the Panhandle Gathering System that was formerly owned by CIG.

Morton County Station. A 2010 investigation indicated chromium impacted groundwater has gone off site to the east. An investigation is planned to determine the extent of the off-site impacts at the Morton County Station owned and operated by CIG.

Rawlins Station. A soil investigation is underway to identify a continuing source of groundwater contamination at the Rawlins Station and Processing Plant owned and operated by CIG.

Fort Morgan Storage Field. Monitoring and mitigation activities are ongoing at the Fort Morgan Storage Field owned and operated by CIG.

B. Compliance Matters – SNG and CIG

Notice of Violation, Albany, Georgia Compressor Station. SNG received a notice of violation (NoV) from the Georgia Environmental Protection Division (GEPD) in April 2011 for excessive excursions identified in the second semiannual report for 2010 resulting from operating T5 temperature and horsepower parameters outside the permitted range for the Solar Turbine (Unit 3). A performance test was conducted in January 2011 to expand the permitted horsepower range for this emission unit and the test report has been reviewed and approved by the agency. Following the test, no additional excursions are anticipated and therefore no additional enforcement action will be initiated.

Notice of Violation, Wrens, Georgia Compressor Station. On April 4, 2011, GEPD issued a NoV to SNG concerning a failed RICE MACT compliance test conducted on compressor engine No. 3 in December 2010 at SNG’s Wrens, Georgia compressor station. A signed consent order and $1000 payment of the proposed fine was submitted to GEPD. No further enforcement action is anticipated. We have to update EPD on the steps we are undertaking to prevent a failed MACT test in the future as noted in our NoV response. The update is due in six months from the April 21, 2011 NoV response.

Notice of Violation, SNG Bear Creek Storage Facility, Louisiana. On June 1, 2011, SNG received a NoV from the Louisiana Department of Environmental Quality (LDEQ) concerning SNG’s Bear Creek Storage Facility. In the NOV, LDEQ alleges that the permitted annual throughput and the volatile organic compound emission limit were exceeded for one of six condensate tanks at the facility.

Fort Morgan Storage Field Administrative Order on Consent. The Colorado Oil and Gas Conservation Commission (COGCC) issued two Notices of Alleged Violations (NOAV) associated with a contractor’s improper disposal of wastes generated at Storage wells #3 and #6. As of May 2011, the COGCC has not pursued enforcement subsequent to CIG’s response. This matter is not considered a significant enforcement risk.

Air Compliance Capital Expenditures. We expect to make capital expenditures for environmental matters of approximately $9 million in the aggregate for 2011 through 2015, 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. Our engines that are subject to the regulations have to be in compliance by October 2013.

Section 1445 of the Internal Revenue Code provides that a transferee (buyer) of a U.S. real property interest must withhold tax if the transferor (seller) is a foreign person. To inform the transferee that withholding of tax is not required upon the disposition of a U.S. real property interest by El Paso Corporation (“El Paso”), the undersigned hereby certifies as follows:

1.	El Paso is not a nonresident alien, foreign corporation, foreign partnership, foreign trust, or foreign estate for purposes of U.S. income taxation (as those terms are defined in the Internal Revenue Code of 1986, as amended and the Treasury regulations thereunder);

2.	El Paso is not a disregarded entity as defined in § 1.1445-2(b)(2)(iii);

3.	El Paso’s taxpayer identifying number is 76-0568816; and

4.	El Paso’s office address is 1001 Louisiana Street, Houston, Texas 77002.

El Paso understands that this certification may be disclosed to the Internal Revenue Service by the buyer and that any false statement contained herein could be punished by fine, imprisonment, or both.

Under penalty of perjury, I declare that I have examined this certification and, to the best of my knowledge and belief, it is true, correct, and complete, and I further declare I have authority to sign this document on behalf of El Paso.
