(ii) The statements made in each of the Preliminary Memorandum and the Final Memorandum under the captions “Risk Factors—Risks Related to Our Business—Our natural gas transportation, gathering and storage operations are subject to FERC rate-making policies that could have an adverse impact on our ability to establish rates that would allow us to recover the full cost of operating our pipelines including a reasonable return and our ability to service our debt,” “Risk Factors— Risks Related to Our Business—Our natural gas transportation and storage operations are subject to extensive regulation by FERC in addition to FERC rules and regulations related to the rates we can charge for our services,” “Risk Factors— Risks Related to Our Business—We are subject to laws and regulations relating to the environment which may expose us to significant costs, liabilities and loss of revenues.

(iii) None of the offering, issuance and sale by the Company of the Securities and the application of the proceeds therefrom as described under the caption “Use of Proceeds” in the Preliminary Memorandum and the Final Memorandum, the execution, delivery and performance of the Purchase Agreement, the Indenture and the Securities by the Company, or the consummation of the transactions contemplated thereby violates or will violate the Natural Gas Act, as amended, or the rules and regulations promulgated thereunder by the Federal Energy Regulatory Commission.

In addition, he shall state that he has participated in conferences with officers and other representatives of the Company, representatives of the independent registered public accounting firm of the Company and representatives of the Initial Purchasers, at which the contents of the Disclosure Package and Final Memorandum and related matters were discussed, and although he did not independently investigate or verify the information set forth in the Disclosure Package and Final Memorandum, and he is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Disclosure Package and Final Memorandum (except to the extent specified in paragraphs (i) and (ii) above), based on the foregoing (relying as to factual matters in respect of the determination of materiality to the extent he deems reasonable and appropriate upon the statements of fact made by officers and other representatives of the Company), no facts have come to his attention that have led such counsel to believe that:

(B)           the Disclosure Package, as of the Execution Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

except that in each case he need express no opinion with respect to the financial statements and notes and schedules thereto or other related financial, accounting and statistical data contained in or omitted from the Disclosure Package or the Final Memorandum or any further amendment or supplement thereto.

(c) The Representatives shall have received from Xxxxxxx Xxxxx LLP, counsel for the Initial Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Disclosure Package, the Final Memorandum (as amended or supplemented at the Closing Date) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and

(ii) since the date of the most recent financial statements included in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, earnings, business or properties of the Company, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

(e) At the Execution Time and on the Closing Date, the Company shall have requested and caused Deloitte & Touche LLP to furnish to the Representatives letters, dated as of the Execution Time and as of the Closing Date, respectively, in form and substance satisfactory to the Representatives and confirming that they are independent certified public accountants with respect to the Company under Rule 101 of the AICPA’s Code of Professional Conduct and its interpretations and rulings and stating in effect that:

(i) on the basis of a reading of the latest unaudited financial statements made available by the Company; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the members, board of directors and committees of the board of directors of the Company; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company as to transactions and events subsequent to December 31, 2007, nothing came to their attention which caused them to believe that:

(A) any unaudited financial statements included in the Preliminary Memorandum or the Final Memorandum do not comply as to form with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Preliminary Memorandum and the Final Memorandum; or

(B) with respect to the period subsequent to December 31, 2007, there were, at a specified date not more than five days prior to the date of the letter, any changes in the long-term debt of the Company or decreases in net current assets or total members’ capital of the Company as compared with the amounts shown on the December 31, 2007 balance sheet included in the Preliminary Memorandum and the Final Memorandum, or for the period from January 1, 2008 to such specified date there were any decreases, as compared with the corresponding period in the preceding year, in revenues, operating income or net income of the Company, except in all instances for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representatives; and

(ii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company) set forth in the Preliminary Memorandum and the Final Memorandum, including the information set forth under the captions “Summary Historical Financial and Operating Data” and “Management’s Discussion and Analysis of Results of Operation and Financial Condition” in the Preliminary Memorandum and the Final Memorandum, agrees with the accounting records of the Company, excluding any questions of legal interpretation.

(f) Subsequent to the Execution Time or, if earlier, the date of the most recent financial statements included in the Disclosure Package (exclusive of any amendment or supplement thereto) and the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6; or (ii) any adverse change, or any development involving a prospective adverse change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of the Company, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

(g) The Securities shall be eligible for clearance and settlement through The Depository Trust Company.

(h) Subsequent to the Execution Time, there shall not have been any downgrading in the rating of any debt securities of the Company or any of its Affiliates by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(i) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representatives.  Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 will be delivered at the office of counsel for the Initial Purchasers, at 000 Xxxxxxxxx Xxx., 00xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, on the Closing Date.

7. Reimbursement of Expenses.  If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally through X. X. Xxxxxx Securities Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

(a) The Company agrees to indemnify and hold harmless each Initial Purchaser, its Affiliates, directors and officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein.

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities (or any amendment or supplement thereto), it being understood and agreed that:  (i) the last paragraph of the cover page of the Preliminary Memorandum and the Final Memorandum (regarding delivery of the Securities) and (ii) (A) the table of Initial Purchasers (including the principal amount of Securities to be purchased by such Initial Purchasers) and (B) the 7th and 8th paragraphs (related to stabilization and syndicate covering transactions), in each case appearing under the heading “Plan of Distribution” in the Preliminary Memorandum and the Final Memorandum, constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum.

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 8 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 8.  If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 8 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred.  In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred.  Any such separate firm for any Initial Purchaser, its Affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by X.X. Xxxxxx Securities Inc. and any such separate firm for the Company, its directors and officers and any control persons of the Company shall be designated in writing by the Company. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.  The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent (such consent not to be unreasonably withheld), but if settled with the consent of the Indemnifying Person or if there be a final judgment for the plaintiff in any such proceeding, the Indemnifying Person agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities.  The relative fault of the Company on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above.  The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim.  Notwithstanding the provisions of this Section 8, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Initial Purchasers' obligations to contribute pursuant to this Section 8 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

9. Default by an Initial Purchaser.  If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser(s) hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchaser(s) shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchaser(s)) the Securities which the defaulting Initial Purchaser(s) agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser(s) agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchaser(s) shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchaser(s) does or do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser(s) or the Company.  In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected.  Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

10. Termination.  This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq Stock Market shall have been suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive.  The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Company or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities.  The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices.  All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to Credit Suisse Securities (USA) LLC, Eleven Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, (fax: 000-000-0000) Attention: LCD-IBD, X.X.

16. Applicable Law.  This Agreement will be governed by and construed in accordance with the laws of the State of New York.

17. Waiver of Jury Trial.  The Company hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18. No Fiduciary Duty.  The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Initial Purchasers and any Affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Company on related or other matters).  The Company agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.
