The Partnership, the Operating Company, Service Sub, L & L Transportation and Inergy Transportation are referred to as the “Partnership Group.” L & L Transportation and Inergy Transportation are sometimes collectively referred to herein as the “Operating Subs.” The Partnership, the Operating Company, New Propane, the General Partners, Service Sub and the Operating Subs are referred to as the “Inergy Parties.”

1. Description of Common Units. The Partnership proposes to issue and sell to the Underwriters 1,750,000 common units (the “Firm Units”) representing limited partner interests in the Partnership (the “Common Units”). The Partnership further proposes to grant to the Underwriters the right to purchase up to an additional 262,500 Common Units (the “Option Units”), as provided in Section 3 of this Agreement. The Firm Units and the Option Units are herein sometimes referred to as the “Units” and are more fully described in the Prospectus hereinafter defined. The offering of the Units will close after the payment date for a two-for-one

unit split that the Partnership announced on December 10, 2003. The Underwriters will therefore receive two Units for each Unit they agree to purchase hereunder and will pay one-half of the purchase price per Unit set forth in Paragraph 2.

2. Purchase, Sale and Delivery of Firm Units. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Partnership agrees to sell 1,750,000 Firm Units (3,500,000 post split) to the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase 1,750,000 Firm Units (3,500,000 post split) from the Partnership at a purchase price of $46.21 per Unit ($23.105 per Unit post split) and the number of such Firm Units set forth opposite the same of such Underwriter in Schedule 1 hereto.

Delivery of the Firm Units will be in book-entry form through the facilities of The Depository Trust Company, New York, New York (“DTC”). Delivery of the documents required by Section 6 hereof with respect to the Units shall be made at or prior to 9:00 a.m., New York City time, on January 14, 2004 at the office of Xxxxxx & Xxxxxx L.L.P., 0000 Xxxxxx Xxxxxx, 0000 Xxxxx Xxxx Xxxxx, Xxxxxxx, XX 00000-0000, or at such other place as may be agreed upon between you and the Partnership (the “Place of Closing”), or at such other time and date not later than five full business days thereafter as you and the Partnership may agree, such time and date of payment and delivery being herein called the “Closing Date.” Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of the Underwriters hereunder.

The Partnership will deliver the Firm Units to the Underwriters, against payment of the purchase price therefor in Federal (same day) Funds by wire transfer to an account at the bank specified by the Partnership.

The Partnership will cause its transfer agent to deposit the Firm Units pursuant to the Full Fast Delivery Program of the DTC.

It is understood that an Underwriter, individually, may (but shall not be obligated to) make payment on behalf of the other Underwriters whose funds shall not have been received prior to the Closing Date for Units to be purchased by such Underwriter. Any such payment by an Underwriter shall not relieve the other Underwriters of any of their obligations hereunder.

It is understood that the Underwriters propose to offer the Units to the public upon the terms and conditions set forth in the Prospectus hereinafter defined.

3. Purchase, Sale and Delivery of the Option Units. The Partnership hereby grants an option to the Underwriters to purchase from the Partnership up to 262,500 Option Units (525,000 post split), on the same terms and conditions as the Firm Units; such option is granted for the purpose of covering any over-allotments in the sale of the Firm Units. No Option Units shall be sold or delivered unless the Firm Units previously have been, or simultaneously are, sold and delivered. The price of any Option Units shall be $46.21 per Unit ($23.105 per Unit post split).

The option is exercisable by you at any time, and from time to time, before the expiration of 30 days from the date of the Prospectus Supplement, hereinafter defined (or, if such 30th day shall be a Saturday or Sunday or a holiday, on the next day thereunder when The Nasdaq National Market (the “Nasdaq”) is open for trading), for the purchase of all or part of the Option Units covered thereby, by notice given by you to the Partnership in the manner provided in Section 12 hereof, setting forth the number of Option Units as to which the Underwriters are exercising the option, and the date of delivery of said Option Units, which date shall not be more than five business days after such notice unless otherwise agreed to by the parties. You may terminate the option at any time, as to any unexercised portion thereof, by giving written notice to the Partnership to such effect.

The allocation of the Option Units may be made as required to eliminate the purchase of fractional Units.

Delivery of the Option Units will be in book-entry form through the facilities of DTC. Delivery of the documents required by Section 6 hereof with respect to the Option Units shall be made at the Place of Closing at or prior to 9:00 a.m., New York City time, on the date designated in the notice given by you as provided above, or at such other time and date as you and the Partnership may agree (which may be the same as the Closing Date), such time and date of payment and delivery being herein called the “Option Closing Date.” Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of the Underwriters hereunder. On the Option Closing Date, the Partnership shall provide the Underwriters such representations, warranties, agreements, opinions, letters, certificates and covenants with respect to the Option Units as are required to be delivered on the Closing Date with respect to the Firm Units.

The Partnership will cause its transfer agent to deposit the Option Units pursuant to the Full Fast Delivery Program of the DTC.

(i) Except as described in the Prospectus or for rights that have been waived, there are no preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any partnership or membership interests or capital stock in the Inergy Parties pursuant to any agreement or other instrument known to such counsel to which any Inergy Party is a party or by which any of them may be bound (other than the Organizational Documents of such entity to which such counsel need not opine). To such counsel’s knowledge, neither the filing of the Registration Statement nor the offering or sale of the Units as contemplated by this Agreement gives rise to any rights for or relating to the registration of any Units or other securities of the Partnership or the Operating Subs, other than as have been waived. To such counsel’s knowledge, except for options granted pursuant to employee benefits plans, qualified unit option plans or other employee compensations plans, there are no outstanding options or warrants to purchase (A) any Common Units, Senior Subordinated Units, Junior Subordinated Units or Incentive Distribution Rights or other partnership interests in the Partnership, (B) membership interests of the Managing General Partner, the Non-Managing General Partner, New Propane, the Operating Company or the Operating Subs or (C) any shares of Service Sub or Inergy Canada.

(ii) None of the offering, issuance and sale by the Partnership of the Units to be sold by it hereunder, the execution, delivery and performance of this Agreement by the Inergy Parties that are parties hereto, or the consummation by each of them of the transactions contemplated hereby (A) constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, any agreement, lease or instrument known to such counsel (excluding any Organizational Document and any other agreement filed or incorporated by reference as an exhibit to the Registration Statement, as to which such counsel need not express an opinion) to which any of the Inergy Parties or any of their properties may be bound, or (B) will result, to the knowledge of such counsel, in any violation of any judgment, order, decree, rule or regulation of any court or arbitrator or governmental agency having jurisdiction over the Inergy Parties or any of their assets or properties, which breaches, violations, defaults or liens, in the case of

(iii) To the knowledge of such counsel, none of the Inergy Parties is in (A) violation of its Organizational Documents, or of any law, statute, ordinance, administrative or governmental rule or regulation applicable to it or of any decree of any court or governmental agency or body having jurisdiction over it which violation would reasonably be expected to have a Material Adverse Effect or (B) breach, default (or an event which, with notice or lapse of time or both, would constitute such a default) or violation in the performance of any obligation, agreement or condition contained in any bond, debenture, note or any other evidence of indebtedness or in any agreement, indenture, lease or other instrument to which it is a party or by which it or any of its properties may be bound, which breach, default or violation would, if continued, have a Material Adverse Effect or could materially impair the ability of any of the Inergy Parties to perform their obligations under this Agreement.

(iv) To the knowledge of such counsel, each of the Inergy Parties has such permits as are necessary to own its properties and to conduct its business in the manner described in the Prospectus, subject to such qualifications as may be set forth in the Prospectus and except for such permits which, if not obtained, would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect and, to the knowledge of such counsel, none of the Inergy Parties has received any notice of proceedings relating to the revocation or modification of any such permits which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect.

(v) Except as described in the Prospectus, to the knowledge of such counsel, there is no litigation, proceeding or governmental investigation pending or threatened against any of the Inergy Parties or to which any of the Inergy Parties is a party or to which any of their respective properties is subject, which, if adversely determined to such Inergy Parties, is reasonably likely to have a Material Adverse Effect.

In addition, such counsel shall state that she has participated in conferences with officers and other representatives of the Inergy Parties and the independent public accountants of the Partnership and the Underwriters, at which the contents of the Registration Statement and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing on, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement or the Prospectus, based on the foregoing, no facts have come to such counsel’s attention that cause such counsel to believe that the Registration Statement (other than (i) the financial statements included therein, including the notes and

schedules thereto and the auditors’ reports thereon, and (ii) the other financial and statistical data included therein, as to which such counsel need express no belief), as of its effective date contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus (other than (i) the financial statements included therein, including the notes and schedules thereto and the auditors’ reports thereon, and (ii) the other financial and statistical data included therein, as to which such counsel need express no belief), as of its issue date and the Closing Date contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f) At the time of execution of this Agreement and on the Closing Date (and, if applicable, the Option Closing Date), the Underwriters shall have received from Ernst & Young LLP a letter or letters, in form and substance satisfactory to the Underwriters, addressed to the Underwriters and dated the date hereof (i) confirming that they are independent public accountants within the meaning of the 1933 Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, and (ii) stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus, as of a date not more than five days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily

covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings.

(h) There shall not have occurred any of the following: (i) trading in securities generally on the Nasdaq shall have been suspended; (ii) trading in any securities of the Partnership on any exchange or in the over-the-counter market shall have been suspended, the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (iii) a banking moratorium shall have been declared by federal or state authorities, (iv) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (v) there shall have occurred such a material adverse change in general economic, political or financial conditions including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such), as to make it, in the judgment of Xxxxxx Brothers Inc., so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or sale of the Units being delivered on the Closing Date on the terms and in the manner contemplated by the Prospectus.

(i) You shall have received a certificate, dated the Closing Date (and, if applicable, the Option Closing Date) and signed by (x) the President and Chief Executive Officer and (y) the Vice President and Chief Financial Officer of the Managing General Partner, in their capacities as such, stating that:

7. Indemnification and Contribution.

(a) The Inergy Parties jointly and severally, will indemnify and hold harmless each of the Underwriters from and against any losses, damages or liabilities, joint or several, to which the Underwriters may become subject, under the 1933 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 contained in the Registration Statement or any amendment or supplement thereto or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus 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 Underwriters for any legal or other out-of-pocket expenses incurred by such Underwriter 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 7(d) 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 Registration Statement, the Prospectus or any other prospectus relating to the Units, or any such amendment or supplement, in reliance upon and in conformity with written information relating to the Underwriters furnished to the Partnership by you, expressly for use in the preparation thereof (as provided in Section 13 hereof).

(b) Each of the Underwriters, severally and not jointly, will indemnify and hold harmless the Inergy Parties from and against any losses, damages or liabilities to which the Inergy Parties may become subject, under the 1933 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 contained in the Registration Statement or any amendment or supplement thereto, or arise out of are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus 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 Registration Statement, the Prospectus or any such amendment or supplement, in reliance upon and in conformity with written information relating to the Underwriters furnished to the Partnership by you, 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 7(d) hereof) any such settlement is effected with the written consent of the Underwriters).

(c) Promptly after receipt by an indemnified party under Section 7(a) or 7(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 7(a) or 7(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 except to the extent that it has been prejudiced in any material respect by such failure or from any liability that it may have to any such indemnified party otherwise than under Section 7(a) or 7(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 7(a) or 7(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 7(a) or 7(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 7(a) or 7(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 7(a) or 7(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 7 is unavailable to or insufficient to indemnify or hold harmless an indemnified party under Section 7(a) or 7(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 7(a) or 7(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 Underwriters on the other hand, from the offering of the Units. 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 7(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 Underwriters, 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 Underwriters, 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 Partnership bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault, as applicable, of the Inergy Parties, on the one hand and the Underwriters, 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 Underwriters, 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 Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(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 7(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 7(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 7(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter 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 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Inergy Parties under this Section 7 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 and to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of each of the Underwriters under this Section 7 shall be in addition to any liability that the respective Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Partnership and the Managing General Partner who signed the Registration Statement and to each person, if any, who controls the Inergy Parties within the meaning of the 1933 Act.

8. Representations and Agreements to Survive Delivery. The respective representations, warranties, agreements and statements of the Inergy Parties, and the Underwriters, as set forth in this Agreement or made by or on behalf of them pursuant to this Agreement, shall remain operative and in full force and effect regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriters or any controlling person of any of the Underwriters, the Inergy Parties or any of their officers, directors or any controlling persons and shall survive delivery of and payment for the Units hereunder.

9. Defaulting Underwriter.

If any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Firm Units which the defaulting Underwriter agreed but failed to purchase on the Closing Date in the respective proportions which the number of Firm Units set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of Firm Units set opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Firm Units on the Closing Date if the total number of Firm Units which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of Firm Units to be purchased on the Closing Date and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of the Firm Units which it agreed to purchase on the Closing Date, pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Underwriters 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 Firm Units to be purchased on the Closing Date. If the remaining Underwriters, or other underwriters satisfactory to the Underwriters, do not elect to purchase the Firm Units which the defaulting Underwriter or Underwriters agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or any Inergy Party except that the Inergy Parties will continue to be liable for the payment of expenses to the extent set forth in Section 11. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 9, purchases Firm Units which a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Inergy Parties for damages caused by its default. If other underwriters are obligated or agree to purchase the Firm Units of a defaulting or withdrawing Underwriter, either the Underwriters or the Partnership 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 Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

10. Termination.

Dear Sirs:

The undersigned understands that you, as the underwriters (the “Underwriter”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Inergy Parties providing for the purchase by you of common units, each representing a limited partner interest (the “Common Units”) in the Partnership, and that the Underwriters propose to reoffer the Common Units to the public (the “Offering”). Capitalized terms used but not defined herein have the meanings given to them in the Underwriting Agreement.

In consideration of the execution of the Underwriting Agreement by you, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Xxxxxx Brothers Inc, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Units (including, without limitation, Common Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Units that may be issued upon exercise of any option or warrant) or securities convertible into or exchangeable for Common Units owned by the undersigned on the date of execution of this Lock-up Letter Agreement or on the date of the completion of the Offering, or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, for a period of 90 days from the date of the Prospectus.

In furtherance of the foregoing, the Partnership and its Transfer Agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Partnership notifies you that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the

Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Units, the undersigned will be released from [his/her] obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Partnership and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership and the Underwriters.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the [heirs and personal representatives] (for individuals) [successors and assigns] (for nonnatural persons) of the undersigned.

Yours very truly,
