“THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS NOTE MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS NOTE IS HEREBY NOTIFIED THAT THE SELLER OF THIS NOTE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF INERGY MIDSTREAM, L.P. AND NRGM FINANCE CORP. THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO AN ISSUER, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (IV) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), OR (V) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, AND IN EACH OF CASES (I) THROUGH (V) IN ACCORDANCE

WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY SUBSEQUENT PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.”

You have advised the Issuers that you will make offers (the “Exempt Resales”) of the Notes purchased by you hereunder on the terms set forth in the Offering Memorandum, as amended or supplemented, solely to (i) persons whom you reasonably believe to be “qualified institutional buyers” as defined in Rule 144A under the Act (“QIBs”) and (ii) outside the United States to certain persons in offshore transactions in reliance on Regulation S under the Act. Those persons specified in clauses (i) and (ii) are referred to herein as the “Eligible Purchasers.” You will offer the Notes to Eligible Purchasers initially at a price equal to 100% of the principal amount thereof. Such price may be changed at any time without notice.

Holders (including subsequent transferees) of the Notes will have the registration rights set forth in the registration rights agreement attached hereto as Exhibit C (the “Registration Rights Agreement”) among the Inergy Parties and the Initial Purchasers to be dated as of the Closing Date, for so long as such Notes constitute “Registrable Securities” (as defined in the Registration Rights Agreement). Pursuant to the Registration Rights Agreement, the Inergy Parties will agree to file with the Commission under the circumstances set forth therein, a registration statement under the Act relating to the Issuers’ 6.00% Senior Notes due 2020 (the “Exchange Notes”) and the Guarantors’ Exchange Guarantees (the “Exchange Guarantees”) to be offered in exchange for the Notes and the Guarantees. Such portion of the offering is referred to as the “Exchange Offer.”

3. Representations, Warranties and Agreements of the Inergy Parties. The Inergy Parties, jointly and severally, represent, warrant and agree as follows:

(a) No Material Misstatements or Omissions. The Offering Memorandum, as of the Applicable Time, does not, and at the Closing Date will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading, except that this representation and warranty does not apply to statements in or omissions from the Offering Memorandum made in reliance upon and in conformity with information relating to the Initial Purchasers furnished to the Issuers in writing by or on behalf of the Initial Purchasers expressly for use therein, which information is specified in Section 13.

(b) No Similar Class of Registered Securities. When the Notes and Guarantees are issued and delivered pursuant to this Agreement, such Notes and Guarantees will not be of the same class (within the meaning of Rule 144A under the Act) as securities of the Issuers or the Guarantors that are listed on a national securities exchange registered under Section 6 of the Exchange Act or that are quoted in a United States automated inter-dealer quotation system.

(c) Incorporated Documents. The Incorporated Documents, when filed with the Commission, conformed or will conform, as the case may be, in all material respects to the requirements of the Exchange Act, and the rules and regulations (“Rules and Regulations”) of the United States Securities and Exchange Commission (the “Commission”) thereunder, and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) No Issuer Written Communications. The Partnership (including its agents and representatives, other than the Initial Purchasers in their capacity as such) has not prepared, made, used, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any written communication that constitutes an offer to sell or solicitation of an offer to buy the Notes (each such communication by the Partnership or its agents and representatives (other than a communication referred to in clause (i) below) an “Issuer Written Communication”) other than (i) the Offering Memorandum and (ii) any electronic road show or other written communications, in each case used in accordance with Section 6(l). Each such Issuer Written Communication, when taken together with the Offering Memorandum as of the Applicable Time, did not, and at the Closing Date will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Partnership makes no representation and warranty with respect to any statements or omissions made in each such Issuer Written Communication in reliance upon and in conformity with information relating to any Initial Purchaser furnished to the Partnership in writing by such Initial Purchaser expressly for use in any Issuer Written Communication.

(e) No Solicitation or Advertisement

(i) Assuming that your representations and warranties in Section 4(b) are true, the purchase and resale of the Notes pursuant hereto (including pursuant to the Exempt Resales) is exempt from the registration requirements of the Act. No form of general solicitation or general advertising within the meaning of Regulation D (including, but not limited to, advertisements, articles, notices or other communications published in any newspaper, magazine or similar medium or broadcast over television or radio, or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising) was used by any of the Inergy Parties or any of their respective representatives (other than you, as to whom the Inergy Parties make no representation) in connection with the offer, issuance and sale of the Notes.

(ii) No form of general solicitation or general advertising was used by any of the Inergy Parties or any of their respective representatives (other than you, as to whom the Inergy Parties make no representation) with respect to Notes sold outside the United States to non-U.S. persons (as defined in Rule 902 under the Act) by means of any directed selling efforts within the meaning of Rule 902 under the Act, and the Issuers, any affiliate of the Issuers and any person acting on its or their behalf (other than you, as to whom the Issuers and the Guarantors make no representation) have complied with and will implement the “offering restrictions” required by Rule 902.

(f) No Order Preventing Exempt Resales. The Preliminary Offering Memorandum and Offering Memorandum have been prepared by the Inergy Parties for use by the Initial Purchasers in connection with the Exempt Resales. No order or decree preventing the use of the Preliminary Offering Memorandum or the Offering Memorandum, or any order asserting that the transactions contemplated by this Agreement are subject to the registration requirements of the Act has been issued and no proceeding for that purpose has commenced or is pending or, to the knowledge of the Inergy Parties, is contemplated.

(m) The Partnership will advise the Initial Purchasers promptly, and confirm such advice in writing, (i) of the issuance by any governmental or regulatory authority of any order preventing or suspending the use of any of the Offering Memorandum as of the Applicable Time, any Issuer Written Communication or the Final Offering Memorandum or the initiation or threatening of any proceeding for that purpose; (ii) of the occurrence of any event at any time prior to the completion of the initial offering of the Notes as a result of which any of the Offering Memorandum as of the Applicable Time, any Issuer Written Communication or the Final Offering Memorandum as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when such Offering Memorandum, Issuer Written Communication or the Final Offering Memorandum is delivered to a purchaser, not misleading; and (iii) of the receipt by the Partnership of any notice with respect to any suspension of the qualification of the Notes for offer, and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Partnership will use its reasonable best efforts to

prevent the issuance of any such order preventing or suspending the use of any of the Offering Memorandum as of the Applicable Time, any Issuer Written Communication or the Final Offering Memorandum or suspending any such qualification of the Notes and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

8. Indemnification and Contribution.

(a) The Inergy Parties, jointly and severally, will indemnify and hold harmless each of the Initial Purchasers and their respective directors, officers, employees, affiliates and agents and each person, if any, who controls (within the meaning of Section 15 of the Act) such Initial Purchaser from and against any losses, damages or liabilities, joint or several, to which the Initial Purchasers may become subject, under the Act, or otherwise, insofar as such losses, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact included in the Preliminary Offering Memorandum, the Pricing Disclosure Supplement, the Final Offering Memorandum, any Issuer Written Communication, or in any amendment or supplement thereto, or arise out of or are based upon any omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and will reimburse each of the Initial Purchasers for any legal or other out-of-pocket expenses incurred by such Initial Purchasers in connection with investigating, preparing, pursuing or defending against or appearing as a third party witness in connection with any such loss, damage, liability or action or claim, including, without limitation, any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to the indemnified party, as such expenses are incurred (including such losses, damages, liabilities or expenses to the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 8(c) hereof) any such settlement is effected with the written consent of the Partnership); provided, however, that the Inergy Parties shall not be liable in any such case to the extent, but only to the extent, that any such loss, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Offering Memorandum, the Pricing Disclosure Supplement, the Final Offering Memorandum, any Issuer Written Communication, or in any amendment or supplement thereto, in reliance upon and in conformity with written information relating to the Initial Purchasers furnished to the Issuers by you, expressly for use in the preparation thereof, which information is specified in Section 13.

(b) Each of the Initial Purchasers, severally and not jointly, will indemnify and hold harmless the Inergy Parties and their respective affiliates from and against any losses, damages or liabilities to which the Inergy Parties may become subject, under the Act or otherwise, insofar as such losses, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact included in the Preliminary Offering Memorandum, the Pricing Disclosure Supplement, the Final Offering Memorandum, any Issuer Written Communication, or in any amendment or supplement thereto, or arise out of or are based upon any omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Disclosure Supplement, the Final Offering Memorandum, any Issuer Written Communication, or in any amendment or supplement thereto, in reliance upon and in conformity with written information relating to such Initial Purchaser furnished to the Issuers by such Initial Purchaser, expressly for use in the preparation thereof (as provided in Section 13 hereof), and will reimburse the Inergy Parties for any legal or other expenses incurred by the Inergy Parties in connection with investigating or defending any such action or claim as such expenses are incurred (including such losses, damages, liabilities or expenses to the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 8(d) hereof) any such settlement is effected with the written consent of the Initial Purchasers).

(c) Promptly after receipt by an indemnified party under Section 8(a) or 8(b) hereof of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under Section 8(a) or 8(b) hereof, notify each such indemnifying party in writing of the commencement thereof, but the failure so to notify such indemnifying party shall not relieve such indemnifying party from any liability it may have under Section 8(a) or 8(b) hereof except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure, and such failure shall not relieve such indemnifying party from any liability it may have to any such indemnified party otherwise than under Section 8(a) or 8(b) hereof. In case any such action shall be brought against any such indemnified party and it shall notify each indemnifying party of the commencement thereof, each such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party under Section 8(a) or 8(b) hereof similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of such indemnified party, be counsel to such indemnifying party), and, after notice from such indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under Section 8(a) or 8(b) hereof for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. The indemnified party shall have the right to employ its own counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party at the expense of the indemnifying party has been authorized by the indemnifying party, (ii) the indemnified party shall have been advised by such counsel that there may be a conflict of interest between the indemnifying party and the indemnified party in the conduct of the defense, or certain aspects of the defense, of such action (in which case the indemnifying party shall not have the right to direct the defense of such action with respect to those matters or aspects of the defense on which a conflict exists or may exist on behalf of the indemnified party) or (iii) the indemnifying party shall not in fact have employed counsel reasonably satisfactory to such indemnified party to assume the defense of such action, in any of which events such fees and expenses to the extent applicable shall be borne, and shall be paid as incurred, by the indemnifying party. If at any time such indemnified party shall have requested such indemnifying party under Section 8(a) or 8(b) hereof to reimburse such indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 8(a) or 8(b) hereof effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of such request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request for reimbursement prior to the date of such settlement. No such indemnifying party shall, without the written consent of such indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be

sought hereunder (whether or not such indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of such indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any such indemnified party. In no event shall such indemnifying parties be liable for the fees and expenses of more than one counsel, including any local counsel, for all such indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to indemnify or hold harmless an indemnified party under Section 8(a) or 8(b) hereof in respect of any losses, damages or liabilities (or actions or claims in respect thereof) referred to therein, then each indemnifying party under Section 8(a) or 8(b) hereof shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages or liabilities (or actions or claims in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Inergy Parties on the one hand, and the Initial Purchasers on the other hand, from the offering of the Notes. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 8(c) hereof and such indemnifying party was prejudiced in a material respect by such failure, then each such indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault, as applicable, of the Inergy Parties on the one hand, and the Initial Purchasers, on the other hand in connection with the statements or omissions that resulted in such losses, damages or liabilities (or actions or claims in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by, as applicable, the Inergy Parties on the one hand and the Initial Purchasers, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Issuers bear to the total discounts and commissions received by the Initial Purchasers. The relative fault, as applicable, of the Inergy Parties, on the one hand and the Initial Purchasers, on the other hand, 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 Inergy Parties on the one hand, or the Initial Purchasers on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Inergy Parties and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by such an indemnified party as a result of the losses, damages or liabilities (or actions or claims in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Notes purchased by it and distributed to the public were offered to the public exceeds the amount of any damages that such Initial Purchasers 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.

(e) The obligations of the Inergy Parties under this Section 8 shall be in addition to any liability that the Inergy Parties may otherwise have and shall extend, upon the same terms and conditions, to each officer, director, employee, agent or other representative of each Initial Purchaser and to each person, if any, who controls any Initial Purchaser within the meaning of the Act; and the obligations of each of the Initial Purchasers under this Section 8 shall be in addition to any liability that the respective Initial Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Issuers and the General Partner and to each person, if any, who controls the Inergy Parties within the meaning of the Act.

9. Defaulting Initial Purchasers. If, on the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to purchase the Notes that the defaulting Initial Purchaser agreed but failed to purchase on the Closing Date in the respective proportions that the principal amount of the Notes set opposite the name of each remaining non-defaulting Initial Purchaser in Schedule I hereto bears to the total principal amount of the Notes set opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule I hereto; provided, however, that the remaining non-defaulting Initial Purchasers shall not be obligated to purchase any of the Notes on the Closing Date if the total number of Notes that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 9.09% of the total number of Notes to be purchased on the Closing Date, and any remaining non-defaulting Initial Purchasers shall not be obligated to purchase more than 110% of the number of Notes that it agreed to purchase on the Closing Date pursuant to the terms of Section 4. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers, or those other Initial Purchasers satisfactory to the Initial Purchasers who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Notes to be purchased on the Closing Date. If the remaining Initial Purchasers or other Initial Purchasers satisfactory to the Initial Purchasers do not elect to purchase the Notes that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or the Inergy Parties, except that the Inergy Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 11 and 12.

Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Inergy Parties for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Notes of a defaulting or withdrawing Initial Purchaser, either the remaining Initial Purchasers or the Issuers may postpone the Closing Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Issuers or counsel for the Initial Purchasers may be necessary in the Offering Memorandum or in any other document or arrangement.

10. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers by notice given to and received by the Issuers prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Section 7(o) shall have occurred or if the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement.

11. Cost and Expenses. The Partnership will bear and pay the costs and expenses incident to the offering of the Notes, including, without limitation, (a) all expenses (including stock transfer taxes) incurred in connection with the delivery to the Initial Purchasers of the Notes, (b) the fees and expenses of the Issuers’ counsel and accountants, (c) the preparation, printing, filing, delivery and shipping of the Preliminary Offering Memorandum and the Offering Memorandum and any amendments or supplements thereto and the printing, delivery and shipping of this Agreement, the Indenture, the Registration Rights Agreement, the Transaction Agreements, the Escrow Agreement, all Blue Sky Memoranda and all other agreements, memoranda, correspondence and other documents printed and delivered in connection therewith and with the Exempt Resales (but not, however, legal fees and expenses of your counsel incurred in connection with any of the foregoing other than fees of such counsel plus reasonable disbursements incurred in connection with the preparation, printing and delivery of such Blue Sky Memoranda), (d) the furnishing of copies of such documents to the Initial Purchasers, (e) the issuance and delivery by the Issuers of the Notes and by the Guarantors of the Guarantees and any taxes payable in connection therewith, (f) the qualification of the Notes and the Exchange Notes for the offer, issuance and sale under the securities or Blue Sky laws of the several states (including, without limitation, the reasonable fees and disbursements of your counsel relating to such registration or qualification), (g) the furnishing of such copies of the Preliminary Offering Memorandum and the Offering Memorandum, and all amendments and supplements thereto, as may be reasonably requested for use in connection with the Exempt Resales, (h) the preparation of certificates for the Notes (including, without limitation, printing and engraving thereof), (i) the approval of the Notes by DTC for “book-entry” transfer (including fees and expenses of counsel), (j) the rating of the Notes and the Exchange Notes, (k) the obligations of the Trustee, any agent of the Trustee and the counsel for the Trustee in connection with the Indenture, the Notes, the Guarantees, the Exchange Notes and the Exchange Guarantees, (l) the performance by the Inergy Parties of their other obligations under this Agreement, (m) all travel expenses, including one-half of the expenses relating to chartered aircraft and all accommodation expenses, of representatives of the Partnership in connection with the offering of the Notes, and (n) all of the other costs and expenses incident to the performance by the Issuers of the offering of the Notes; provided, that the Initial Purchasers will bear and pay all of their own costs and expenses, including the fees and expenses of counsel, and any advertising costs and expenses incurred by any of the Initial Purchasers incident to the offering of the Notes.

If this Agreement is terminated by you in accordance with the provisions of Section 10, the Issuers shall reimburse the Initial Purchasers for all of their reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel to the Initial Purchasers.

12. Reimbursement of Initial Purchasers’ Expenses. If the Issuers fail to tender the Notes for delivery to the Initial Purchasers by reason of any failure, refusal or inability on the part of the Inergy Parties to perform any agreement on their part to be performed, or because any other condition of the obligations hereunder required to be fulfilled by the Inergy Parties is not fulfilled, the Inergy Parties shall reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Initial Purchasers in

connection with this Agreement and the proposed purchase of the Notes, and upon demand the Inergy Parties shall pay the full amount thereof to the Initial Purchasers. If this Agreement is terminated pursuant to Section 7(o)(i), Section 7(o)(iii), Section 7(o)(iv) or Section 7(o)(v) by reason of the default of one or more Initial Purchasers, the Inergy Parties shall not be obligated to reimburse any defaulting Initial Purchaser on account of those expenses.

13. Information Furnished by the Initial Purchasers. The statements set forth in the subsection entitled “Commissions and Discounts,” the third sentence of the subsection entitled “New Issue of Notes,” and the first, second, third and fourth sentences of the subsection entitled “Short Positions,” all under the section captioned “Plan of Distribution” in the Offering Memorandum, constitute the only information furnished by or on behalf of the Initial Purchasers through you as such information is referred to in Sections 3(d), 8(a) and 8(b) hereof.

16. Research Independence. In addition, each of the Inergy Parties acknowledges that the Initial Purchasers’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Initial Purchasers’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to any of the Inergy Parties and/or the offering that differ from the views of its investment bankers. Each of the Inergy Parties hereby waives and releases, to the fullest extent permitted by law, any claims any of the Inergy Parties may have against the Initial Purchasers with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to any of the Inergy Parties by such Initial Purchasers’ investment banking divisions.
