NONCOMPETITION AGREEMENT

Exhibit 10.2

NONCOMPETITION AGREEMENT

This Noncompetition Agreement (this “Noncompetition Agreement”) is entered into on December     , 2004, among Star Gas Partners, L.P., a Delaware limited partnership, Star Gas LLC, a Delaware limited liability company (collectively, the “Sellers”), and Inergy Propane, LLC, a Delaware limited liability company (“Buyer”).

On November 18, 2004, Buyer, the Sellers and Inergy, L.P. entered into an Interest Purchase Agreement (the “Interest Purchase Agreement”) pursuant to which Buyer is purchasing all of the propane business and certain other related businesses of the Sellers. Section 4.4 of the Interest Purchase Agreement contemplates and requires the execution and delivery of this Noncompetition Agreement as a condition to the consummation of the transactions under the Interest Purchase Agreement.

In consideration of the amounts paid by Buyer to the Sellers pursuant to the Interest Purchase Agreement, the parties hereby agree as follows:

1. Covenant Not to Compete.

(a) The Sellers hereby acknowledge and recognize the highly competitive nature of the Business (as defined in the Interest Purchase Agreement) being acquired by Buyer pursuant to the Interest Purchase Agreement, including the intellectual property, trade secrets and confidential information of the Business being acquired. Accordingly, except as provided in Sections 1(b) and 1(c), the Sellers hereby agree that they will not, directly or indirectly, during the period commencing on the date of this Agreement and ending on the fifth anniversary of such date (the “Noncompetition Period”), own, manage, operate, control or participate in the ownership, management, operation or control of, or have any interest, financial or otherwise, in or act as a partner, manager, member, principal, agent, representative, consultant or independent contractor of, licensor to, or lessor to, or in any way assist, any Person (as defined in the Interest Purchase Agreement) in the conduct of any business that is engaged or may become engaged in any business competitive to the Business now or at any time during the Noncompetition Period in either (i) any of the Prohibited States (as defined below) or (ii) the business locations in which the Business was conducted on the date of this Agreement or within 50 miles of any of such locations. In addition, the Sellers will not, directly or indirectly, during the Noncompetition Period use or license in connection with any propane-related activities any name, trade name or trademark that was previously used in connection with the Business or that is similar to those previously used in connection with the Business in either (A) any of the Prohibited States or (B) the business locations in which the Business was conducted on the date of this Agreement or within 50 miles of any of such locations. “Prohibited States” means each of the following states: Florida, Indiana, Maine, Massachusetts, Michigan, Minnesota and Ohio.

(b) Notwithstanding anything in Section 1(a) to the contrary, the Sellers may own up to 5% of the outstanding equity securities in any Person that is listed upon a national stock exchange or actively traded in the over-the-counter market.

(c) Notwithstanding anything in Section 1(a) to the contrary, the Sellers may (i) continue to be involved in the Business, but only to the limited extent involved in the Business on the date of this Agreement (after giving effect to the consummation of the transactions contemplated by the Interest Purchase Agreement) and (ii) expand their involvement in the Business pursuant to the Sellers acquiring a third party (or its assets or operations) already engaged in the Business prior to such acquisition, so long as the gross revenues of such acquired third party for the most-recently completed fiscal year prior to such acquisition and during the current fiscal year (after giving effect, on a pro forma basis, to the acquisition of propane-related assets and the disposition of non-propane-related assets) generated by such acquired third party from propane-related activities is less than 10% of the total gross revenues of such acquired third party for such period.

2. Potential Unenforceability of Section 1. Although the Sellers and Buyer consider the restrictions contained in Section 1 to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in Section 1 is an unreasonable or otherwise unenforceable restriction against the Sellers, neither this Noncompetition Agreement nor the provisions of Section 1 will be rendered void, but will be deemed amended as to such restriction as such court may judicially determine or indicate to be reasonable or, if such court does not so determine or indicate, to the maximum extent that any pertinent statute or judicial decision may indicate to be a reasonable restriction under the circumstances.

3. Specific Performance. Recognizing that irreparable damage will result to Buyer in the event of the breach or threatened breach of any of the foregoing covenants and assurances by the Sellers contained in Section 1, and that Buyer’s remedies at law for any such breach or threatened breach will be inadequate, Buyer and its successors and permitted assigns, in addition to such other remedies that may be available to them, are entitled to, and the Sellers agree not to oppose Buyer’s request for, an injunction, including a mandatory injunction, to be issued by any court of competent jurisdiction ordering compliance with this Noncompetition Agreement or enjoining and restraining the Sellers, and each and every Person acting in concert or participation with the Sellers, from the continuation of such breach and, in addition thereto, the Sellers will pay to Buyer all ascertainable damages, including costs and reasonable attorneys’ fees sustained by Buyer by reason of the breach or threatened breach of such covenants and assurances. Buyer is not required to obtain a bond in an amount greater than $1,000. The covenants and obligations of the Sellers set forth in Section 1 are in addition to and not in lieu of or exclusive of any other obligations and duties of the Sellers to Buyer, whether express or implied in fact or in law.

4. Entire Agreement; Modification. This Noncompetition Agreement, along with the Interest Purchase Agreement, embodies the entire agreement between the parties with respect to the subject matter hereof. This Noncompetition Agreement may not be amended or modified except by a writing signed by an authorized representative of the party against whom enforcement of the change is sought. No waiver of the performance or breach of, or default under, any condition or obligation of this Noncompetition Agreement will be deemed to be a waiver of any other performance, or breach of, or default under the same or any other condition or obligation of this Noncompetition Agreement.

5. Waiver of Breach. The waiver by any party, or the failure by either party to claim a breach (or give notice with respect thereto), of any provision of this Noncompetition

Agreement will not be, or be deemed to be, a waiver of any subsequent breach, or deemed to affect in any way the effectiveness, of such provision.

6. Parties in Interest and Assignment.

(a) This Agreement is binding upon and is for the benefit of the parties and their respective successors and permitted assigns. Except as expressly provided in this Agreement, nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties or their respective successors and permitted assigns any rights, remedies or obligations or liabilities under or by reason of this Agreement.
