The Sellers and Star/Petro have paid or will pay all Taxes applicable to, arising out of or in connection with their allocable share of profits, income, gain or other taxable receipts or payments from the Operating Company for any period or portion thereof, through and including the Closing Date and the Merger.

2.4 Creation of New Buyer GP; Purchase of General Partner Interest. Prior to the Closing, Buyer will form a new Delaware limited liability company, wholly-owned by Buyer (the “New Buyer GP”). At the Closing, the General Partner will sell and assign the General Partner Interest to the New Buyer GP, and the New Buyer GP will purchase the General Partner Interest from the General Partner.

2.5 Purchase of Limited Partner Interest. At the Closing, the Partnership will sell and assign the Limited Partner Interest to Buyer, and Buyer will purchase the Limited Partner Interest from the Partnership.

3.1 Aggregate Purchase Price. The aggregate purchase price (the “Purchase Price”) for the General Partner Interest and the Limited Partner Interest is (A) plus (B) where (A) is $475,000,000, as adjusted pursuant to Section 3.2, and (B) is an amount equal to interest on $475,000,000 at the rate equal to the One-Month LIBOR Rate plus 200 basis points for each day from December 1, 2004 up to, but not including, the Closing Date. The $475,000,000 under (A) is to be paid at the Closing in the amounts set forth below, and the amount under (B) will be paid at the Closing in the same proportion as the amounts set forth below. If Buyer retains any portion of the Purchase Price pursuant to Section 9.14, then such reduction will be made in the same proportion as the amounts set forth below.

(a) $47,500 to the General Partner in exchange for the General Partner Interest; and

(b) $474,952,500 to the Partnership in exchange for the Limited Partner Interest.

(a) Buyer will pay to the Sellers an amount equal to $9,500,000 (the “Estimated Working Capital Payment”), as a working capital adjustment to the Purchase Price, based upon an expected level of Working Capital as of November 30, 2004 of $15,000,000. The Estimated Working Capital Payment will be paid by Buyer to the Sellers at the Closing. Thereafter, the Purchase Price will be further increased or decreased in an amount equal to the amount by which Working Capital reflected on the Closing Date Balance Sheet exceeds or is less than $15,000,000. “Working Capital” means the net aggregate dollar amount of current assets (including the long term portion of accounts receivable) less current liabilities (excluding the current portion of long-term debt and accrued interest, intercompany liabilities and all borrowings for working capital purposes) of the Operating Company and Stellar Propane on a consolidated basis, as determined in accordance with GAAP and on a basis consistent with the financial statements of the Partnership included in the SEC Reports and the Propane Business Financials.

(b) Within 60 days after the Closing Date, Buyer will prepare and deliver to the Sellers a consolidated balance sheet of the Operating Company and Stellar Propane as of November 30, 2004 (the “Closing Date Balance Sheet”). The Closing Date Balance Sheet will be prepared in accordance with GAAP and on a basis consistent with the financial statements of the Partnership included in the SEC Reports and the Propane Business Financials. The Closing Date Balance Sheet will attach Buyer’s calculation of the adjustments required to the Purchase Price pursuant to Section 3.2(a). The Sellers and their Representatives may review all work papers and other supporting documentation used by Buyer in or relevant to the creation of the Closing Date Balance Sheet, and may make reasonable inquiries of Buyer’s Representatives,

during the 60 day period in which Buyer is preparing the Closing Date Balance Sheet and for a period of 30 days after receipt of the Closing Date Balance Sheet.

(c) The Closing Date Balance Sheet will become final and binding upon the Sellers for purposes of calculating the adjustment to the Purchase Price hereunder 30 days after delivery thereof to the Sellers unless the Sellers within such time period deliver written notice to Buyer of their disagreement as to any item included in the Closing Date Balance Sheet or in Buyer’s calculation of the adjustment to the Purchase Price required under this Section 3.2 (an “Adjustment Dispute Notice”). Any such Adjustment Dispute Notice must specify in reasonable detail the nature of such disagreement and the basis and supporting evidence for the Sellers’ position with respect to the disputed items. The parties will attempt in good faith for a period of ten days following the date of the Adjustment Dispute Notice to resolve any disagreement and, if they are unable to do so within such period, will submit the disputed items to an independent accounting firm of national reputation (the “Referral Firm”), whose decision with respect to the matters disputed in the Adjustment Dispute Notice will be final and binding. The Referral Firm will render its decision with respect to such matters within 30 days after they are submitted to it. The parties will promptly provide all information and documents within their respective possession that the Referral Firm, in its sole discretion, considers necessary or desirable in order to make its decision with respect to the disputed matters. The fees and expenses of the Referral Firm will be borne equally by the Sellers and Buyer.

(d) Within five days after the Closing Date Balance Sheet is finally determined either through agreement of the parties or through submission to the Referral Firm as described in Section 3.2(c), Buyer will pay to the Sellers (in the same proportion as the payments made pursuant to Section 3.1) or the Sellers will pay to Buyer, as the case may be, by wire transfer the net amount owed pursuant to the Purchase Price adjustment provisions of this Section 3.2.

3.3 Results of Interim Operations. The parties desire to effect the transaction contemplated by this Agreement solely for purposes of economic effect and for accounting treatment as if the Closing occurred at 11:59 p.m. on November 30, 2004. In order to more fully accomplish such economic effect, after November 30, 2004, the Sellers will cause the Operating Company and Stellar Propane to refrain from making any distributions (in cash or otherwise) to their respective partners, shareholders or members or make any capital contribution to a subsidiary other than the Star/Petro Distribution. In addition, the Sellers will, on or prior to the Closing Date, reimburse the Operating Company and Stellar Propane for all amounts paid (whether of interest, principal, fees, prepayment costs, make-whole premiums or other similar costs) during the month of December, 2004 by either the Operating Company or Stellar Propane relating to Indebtedness (including borrowings for working capital purposes) or relating to payments made under Intercompany Agreements excluding payments for actual goods or services provided consistent with past practices.

The Sellers shall promptly, and in any event within two business days following receipt of a Superior Proposal and prior to providing any Person with any material non-public information, notify Buyer of the receipt of the same.

Notwithstanding the foregoing, prior to the Closing, the board of directors of the General Partner may (subject to the terms of this and the following sentence) withdraw or modify its approval or recommendation of this Agreement or the transactions contemplated by this Agreement, approve or recommend a Superior Proposal,

or enter into a Contract or Other Agreement with respect to a Superior Proposal (an “Acquisition Agreement”), in each case at any time after the third business day following the Sellers’ delivery to Buyer of written notice advising Buyer that the board of directors of the General Partner has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the Person making such Superior Proposal; provided, however, that neither the Sellers nor any of their Affiliates may enter into a Contract or Other Agreement with respect to a Superior Proposal unless the Sellers comply with Section 8.8(e).

(e) The Sellers may terminate this Agreement and the Sellers or their Affiliates may enter into an Acquisition Agreement with respect to a Superior Proposal, provided that, prior to any such termination, (i) the Sellers have provided Buyer written notice that they intend to terminate this Agreement pursuant to this Section 8.8(e), identifying the Superior Proposal then determined to be more favorable and the parties thereto, and (ii) at least three full business days after the Sellers have provided the notice referred to in clause (i) above, the Sellers deliver to Buyer (A) a written notice of termination of this Agreement pursuant to this Section 8.8(e), and (B) a wire transfer of immediately available funds in the amount of $20,000,000 (the “Termination Fee”).

The Sellers hereby consent to the use of and reliance on any audited or unaudited financial statements relating to the Operating Company and Stellar Propane reasonably requested by Guarantor to be used in any public filings that Guarantor desires to make under the Securities Act, including any registration statements of Guarantor. In addition, the Sellers will use commercially reasonable efforts to obtain the consent of KPMG LLP to the use of and reliance on such financial statements. Prior to the Closing, the Sellers will provide Buyer and Guarantor such available information, and make available such personnel, as Buyer or Guarantor may reasonably request in order to assist Buyer and Guarantor to obtain financing or raise funds, including any public equity or debt offerings to be registered under the Securities Act.

Thereafter, the parties will file as promptly as practicable all reports or other documents required or requested by the U.S. Federal Trade Commission or the U.S. Department of Justice pursuant to the HSR Act or otherwise including requests for additional information concerning such transactions, so that the waiting period specified in the HSR Act will expire as soon as reasonably possible after the execution and delivery of this Agreement. Without limiting the foregoing, the parties will use commercially reasonable efforts to cooperate and oppose any preliminary injunction sought by the U.S. Federal Trade Commission or the U.S. Department of Justice preventing the consummation of the transactions contemplated by this Agreement.

(b) With respect to any severance, retention, change in control or other similar payment obligations payable by the Sellers to Donald Rainey as a result of the transactions contemplated by this Agreement, the Sellers will use commercially reasonable efforts to amend the Contracts or Other Agreements setting forth such obligations so that (i) half of the lump sum payments that would be made to Donald Rainey on or about the Closing would be paid at such time and (ii) half of the lump sum payments that would be made to him on or about the Closing would be placed in an escrow account on or about the Closing Date, with the amount placed in escrow (plus interest earned on such amount) paid to him on March 31, 2005, provided that the payment of such escrowed funds to him would be contingent upon him continuing to assist Buyer in the operation of the Business until March 31, 2005, it being the understanding of the parties that he would become an employee of Buyer or its Affiliates after the Closing.

8.12 Resignations. At or prior to the Closing, the Sellers will cause all of the officers, directors, trustees and plan administrators of the Operating Company, Stellar Propane and their respective Benefit Plans to resign or to be removed from such offices.

(a) From the date of this Agreement through the Closing Date, in order to afford Buyer the opportunity to determine, in its sole discretion, what employee benefits it will provide to the employees of the Operating Company and Stellar Propane after the Closing Date, and under what plans such employee benefits will be provided, subject to applicable privacy and other Laws, the Sellers will (and will cause the Operating Company and Stellar Propane to) use commercially reasonable efforts to afford to Buyer and its Representatives full and free access in a reasonable manner, upon reasonable notice and at reasonable times, to each of the Sellers’, the Operating Company’s and Stellar Propane’s Benefit Plan documents, including access to all files, records, reports and other data and information relating thereto, and all personnel involved with the administration of such Benefit Plans. The Sellers will also make available to Buyer a copy of the documents and instruments governing each Benefit Plan (including, where applicable, the plan document, summary plan description or other summary, most recent actuarial report, and trust or other funding arrangement).

(b) If and to the extent requested by Buyer, the Sellers and their Affiliates will amend or terminate any Benefit Plan; provided, however, any such amendment or termination will comply with all applicable Laws and will not be required if otherwise prohibited by the terms of the Collective Bargaining Agreements. Any such amendment or termination may be made conditional upon the Closing provided that such amendment or termination becomes effective immediately prior to the Closing.

(c) Buyer will notify the Sellers at least five days prior to the Closing as to (i) whether Buyer desires the Sellers to assign and transfer to Buyer (or cause the Operating

Company and Stellar Propane to assign and transfer to Buyer) any of the Sellers’, the Operating Company’s or Stellar Propane’s health or other benefit plan policies of insurance and (ii) whether (A) it will continue to sponsor the Operating Company’s 401(k) profit sharing plan either as a merged plan with Buyer’s existing 401(k) profit sharing plan or as a separate plan or (B) it desires that the Operating Company’s 401(k) profit sharing plan be terminated prior to the Closing.

(d) For purposes of determining (i) eligibility to participate in or vesting under Buyer’s applicable 401(k) profit sharing plan, (ii) eligibility to participate in applicable health plans and (iii) eligibility to participate in applicable disability plans, individuals who are employees of the Operating Company or Stellar Propane on the Closing Date or who are hired within 15 days after the Closing Date will be given credit for all service as an employee of either the Operating Company or Stellar Propane.

8.16 Amendments to Organizational Documents. Prior to the Closing, the Sellers will amend their Organizational Documents and the Organizational Documents of the Operating Company to effect any amendments of such Organizational Documents required in order to effect the transactions contemplated by this Agreement, including amendments to Sections 10.2, 10.3, 12.1(b) and 13.1(b) of the Amended and Restated Agreement of Limited Partnership of the Operating Company and amendments to such Organizational Documents to allow for the Star/Petro Distribution. Prior to making any such amendments to the Organizational Documents of the Operating Company, the Sellers will obtain the prior approval of Buyer as to the form and substance of such amendments, which consent will not be unreasonably withheld.

(a) Prior to the Closing, Buyer may, in Buyer’s sole judgment and discretion and at Buyer’s sole expense, cause Phase I environmental site assessments (the “Environmental Assessments”) of the Real Property to be conducted by a qualified engineer or environmental

consultant of Buyer’s choice. All Environmental Assessments will be performed in such a manner as to not physically damage the Real Property.

(b) Upon reasonable advance oral or written notice to Joseph P. Cavanaugh, the Sellers will (and will cause the Operating Company and Stellar Propane to) allow Buyer and its Representatives reasonable access to the Real Property for the purpose of conducting the Environmental Assessments. The Sellers or their Representatives may, at their option, participate in the Environmental Assessments, including accompanying Buyer’s Representatives on any physical investigation of the Real Property.

8.18 Certificate of Limited Partnership. Promptly after the Closing, Buyer will cause the Operating Company to amend the certificate of limited partnership of the Operating Company to reflect the fact that the New Buyer GP is the general partner of the Operating Company.

Each and every obligation of Buyer to be performed at or before the Closing hereunder is subject, at Buyer’s election, to the satisfaction or waiver on or prior to the Closing Date of the conditions set forth below. Notwithstanding the failure of any one or more of such conditions, Buyer may nevertheless proceed with Closing without satisfaction, in whole or in part, of any one or more of such conditions, which action will not prejudice Buyer’s right to recover Damages pursuant to Article 11 and, if the Closing occurs and there are any Unsatisfied Conditions, the amount of any adverse economic effect on the Business or the assets associated with the Business (including any diminution in the fair value of the Business) pursuant to Section 9.14.

9.5 Third Party Consents. Subject to the terms of Section 9.14, Buyer has received all necessary consents from (or in lieu thereof waivers of) any Persons, and Buyer has received all filings with, and approvals by, any Persons, in each case, the absence of which would cause Section 5.3(iii) to be violated.

9.11 Resignations. Buyer has received the resignations or evidence of the removals described in Section 8.12.

9.12 Waiting Periods. The filing and waiting period requirements of the HSR Act relating to the transactions contemplated by this Agreement have been complied with and there is no pending action by the U.S. Department of Justice, the U.S. Federal Trade Commission or other Governmental Authority to materially delay or otherwise enjoin the transactions contemplated by this Agreement.

9.13 No Governmental Restraint. There is not in effect any temporary restraining order, preliminary injunction, injunction or other order of any Governmental Authority prohibiting or restraining the Closing of the transactions contemplated by this Agreement.

(a) Provided that there has been no willful breach of this Agreement by the Sellers, other than breaches that do not have an adverse economic effect on Buyer, if the Sellers have performed (or Buyer has waived) all of their respective obligations in Section 8.2 and all of the conditions set forth in Sections 9.6(b), 9.7, 9.8, 9.9, 9.10, 9.11, 9.12 and 9.13 have been satisfied, notwithstanding the failure of one or more of the conditions set forth in Sections 9.1, 9.2, 9.3, 9.4, 9.5 or 9.6(a) to be satisfied, upon notice by the Sellers, Buyer shall, subject to all of the terms of this Section 9.14, proceed with the Closing provided that, in Buyer’s good faith judgment, substantiated in a notice to the Sellers containing specific reference to relevant and available information (the “Damages Notice”), the events, facts or circumstances that have caused one or more of the conditions set forth in Sections 9.1, 9.2, 9.3, 9.4, 9.5 or 9.6(a) to be unsatisfied (the “Unsatisfied Conditions”) have not and are not reasonably likely to cause an adverse economic effect or other Damages (including, solely for the purposes of this Section 9.14, any diminution in the fair value of the Business) in excess of $47,500,000. The Damages Notice will also include Buyer’s good faith estimate (“Buyer’s Damage Estimate”) of the amount of such adverse economic effect or other Damages (including diminution in the fair value of the Business) as a result of such Unsatisfied Conditions. The Sellers shall promptly provide Buyer with all relevant and available documentation and information in the Sellers’ possession or under their control relating to the Unsatisfied Conditions.

(b) If Buyer’s Damage Estimate is less than or equal to $15,000,000, Buyer shall proceed with the Closing and may immediately pursue an indemnity claim pursuant to Article 11. If Buyer’s Damage Estimate exceeds $15,000,000 but is less than or equal to $47,500,000, then Buyer and the Sellers will enter into good faith negotiations to determine a

possible reduction in the Purchase Price. If Buyer and the Sellers cannot agree upon a reduction in the Purchase Price, the Sellers may elect to terminate this Agreement. If the Sellers do not terminate this Agreement, Buyer (i) shall proceed with the Closing, (ii) may withhold a portion of the Purchase Price equal to the amount by which Buyer’s Damage Estimate exceeds $15,000,000, and (iii) may immediately pursue an indemnity claim pursuant to Article 11. If Buyer’s Damages Estimate is in excess of $47,500,000 then this Agreement may be terminated by Buyer or the Sellers.

(c) Any decision by the Sellers not to exercise their termination right pursuant to Section 9.14(b) will not prejudice any defense they may have in any indemnification proceeding under Article 11 or any claim they may have to the remaining portion of the Purchase Price. Any decision by Buyer to reduce the Purchase Price pursuant to Section 9.14(b), and the amount of such reduction, will not prejudice any claim for the actual amount of the adverse economic effect or other Damages (including diminution in the fair value of the Business) as a result of any Unsatisfied Conditions. Unless otherwise agreed by the Sellers and Buyer, the amount of Buyer’s Damage Estimate is not conclusive (and is not to be used by any party as evidence in any dispute) of the final amount of any claim and no party will be deemed to have accepted such amount as determinative of the actual amount of the adverse economic effect or other Damages.

ARTICLE 10. CONDITIONS TO OBLIGATIONS OF THE SELLERS TO CONSUMMATE THE TRANSACTION

Furthermore, if Buyer or any of its Affiliates

(including the Operating Company or Stellar Propane) is required by any Governmental Authorities to clean up any Real Property as a result of a Release of Hazardous Substances, oil, gasoline or petroleum-related wastes disposed prior to the Closing, the Sellers hereby agree to conduct such environmental cleanup solely to the extent such cleanup is related to a Release, including a continuing Release, that began or occurred before the Closing and to the full extent required by any Governmental Authorities having jurisdiction over the subject matter thereof in the most cost-effective manner achievable as determined by laws, regulations, and policies or agreed to by such Governmental Authorities. Notwithstanding any other provisions of this Agreement to the contrary, Sections 11.1 and 11.3 constitute the sole and exclusive indemnity under this Agreement for Damages related to or arising out of Environmental Laws.

(b) Buyer, the Operating Company and Stellar Propane hereby covenant and agree to indemnify, protect, defend and hold harmless the Sellers, and their members, officers, agents, employees, Representatives, successors and assigns from and against any and all Damages (including reimbursement of clean-up costs) directly or indirectly arising from or as a result of (i) claims, actions or causes of action, involving toxic torts, and those seeking administrative enforcement, injunctive relief or reimbursement of investigation and clean-up costs or natural resource damages, solely to the extent they arise out of the post-Closing handling, treatment, storage, disposal or transportation or arranging therefor, by Buyer, the Operating Company or Stellar Propane of any Hazardous Substance, oil, gasoline or other petroleum products at any property, (ii) Buyer, the Operating Company or Stellar Propane accepting, solely after the Closing, any Hazardous Substance for transport to disposal or treatment Facilities, (iii) any Release of Hazardous Substances, oil, gasoline or petroleum products solely to the extent it occurred after the Closing upon, about or into the Real Property, whether or not such Release or threat of a Release occurred as the result of the negligence or misconduct of Buyer, the Operating Company or Stellar Propane or any other third party or otherwise, but excluding any continuing Releases to the extent attributable to Seller in Section 11.3(a)(iii), or (iv) any violation, actual or alleged, of or any other liability under or in connection with any Environmental Law solely to the extent related to conditions created after Closing that affect soil, air, surface water or groundwater.

(c) Buyer, its subsidiaries, successors, and assigns agree to provide the Sellers and its Representatives access to the Real Property as might reasonably be required by the Sellers or its Representatives to perform the obligations of the Sellers under Section 11.3 or as otherwise required by a Governmental Authority. Buyer agrees to fully cooperate with the Sellers in the Sellers’ performance of their obligations under Section 11.3 or as otherwise required by a Governmental Authority. Access and cooperation under this Section 11.3(c) will be provided without any additional compensation to Buyer or its subsequent purchasers, lessees or assignees. To the extent Buyer conveys, leases or assigns any interest in the Business or Real Property, Buyer will by contract and recordation of rights on the land records have its lessees, its assignees and its immediate subsequent purchasers (with which Buyer has privity) agree to this same requirement of access and cooperation. Failure by Buyer to ensure such access or cooperation with respect to a parcel of Real Property will relieve the Sellers of their indemnity obligations under this Section 11.3 with respect to such parcel only to the extent that Seller is prejudiced in carrying out its obligations under this Section 11.3.

(d) Unless required by Law or to mitigate Damages, Buyer (on behalf of itself and its subsidiaries) agrees not to engage in communications, either oral or written, with any

third party, including any Governmental Authority, which communications have the intent of resulting in (i) an allegation of a violation of any Environmental Law related to the Real Property or the Business, (ii) an unnecessary investigation or remediation of any Real Property or environmental conditions related to the Real Property or the Business, or (iii) a claim for Damages related to or arising out of Environmental Laws. Buyer will make reasonable efforts to obtain the agreement of its lessees, its assignees and its immediate subsequent purchasers (with which Buyer has privity) to this same requirement. To the extent that Buyer or any of its subsidiaries breaches this covenant with respect to a parcel of Real Property, the Sellers are relieved from their obligations under this Section 11.3 with respect to such parcel only to the extent that the Sellers are prejudiced in carrying out their obligations under Section 11.3. Notwithstanding any of the foregoing, Buyer and its subsidiaries may engage in communications with their Representatives, contractors and insurance carriers for any purpose even if clauses (i), (ii) and (iii) above result and may communicate with other third parties and Governmental Authorities that are, or which Buyer and its subsidiaries believe in good faith are, necessary to comply with Law, to address a violation of Environmental Law, to mitigate Damages, or to establish a bona fide prospective purchaser, innocent landowner or contiguous landowner defense under Environmental Law, and all such communications will not be construed as a breach of this provision.

11.4 Procedure. All claims for indemnification by a party under this Article 11 (the party claiming indemnification and the party against whom such claims are asserted being referred to as the “Indemnified Party” and the “Indemnifying Party,” respectively) must be asserted and resolved as follows:

(a) If any claim or demand for which an Indemnifying Party would be liable to an Indemnified Party under this Agreement is asserted against or sought to be collected from such Indemnified Party by a third party, such Indemnified Party shall with reasonable promptness give notice (the “Claim Notice”) to the Indemnifying Party of such claim or demand, specifying the nature of and specific basis for such claim or demand and the amount or the estimated amount thereof to the extent then feasible (which estimate is not conclusive of the final amount of such claim and demand). The Indemnifying Party is not obligated to indemnify the Indemnified Party under this Agreement with respect to any such claim or demand if the Indemnified Party fails to notify the Indemnifying Party thereof in accordance with the provisions of this Agreement, and, as a result of such failure, the Indemnifying Party’s ability to defend against the claim or demand is materially prejudiced. The Indemnifying Party has ten days from the delivery or mailing of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such claim or demand, and (ii) whether or not it desires, at the cost and expense of the Indemnifying Party, to defend the Indemnified Party against such claim or demand; provided, however, that any Indemnified Party is hereby authorized, but is not obligated, prior to and during the Notice Period, to file any motion, answer or other pleading that it considers necessary or appropriate to protect its interests or those of the Indemnifying Party. If the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against such claim or demand, the Indemnifying Party shall, subject to the last sentence of this Section 11.4(a), have the right to control the defense against the claim by all appropriate proceedings and any settlement negotiations, provided that to the satisfaction of the Indemnified Party, the Indemnifying Party

shall secure the Indemnified Party against such contested claims by posting a bond or otherwise. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. If the Indemnifying Party fails to respond to the Indemnified Party within the Notice Period, elects not to defend the Indemnified Party, or after electing to defend fails to commence or reasonably pursue such defense, then the Indemnified Party has the right, but not the obligation, to undertake or continue the defense of, and to compromise or settle (exercising reasonable business judgment), the claim or other matter all on behalf, for the account and at the risk of the Indemnifying Party. Notwithstanding the foregoing, if the basis of the proceeding relates to a condition of operations that existed or were conducted both prior to and after the Closing Date or if the Indemnified Party would be otherwise adversely affected as a result of any adverse decision of such proceeding, each party has the same right to participate at its own expense and at its own risk in the proceeding without either party having the right of control.

(b) If requested by the Indemnifying Party, the Indemnified Party will, at the Indemnifying Party’s expense, cooperate with the Indemnifying Party and its counsel in contesting any claim or demand that the Indemnifying Party elects to contest, or, if appropriate and related to the claim in question, in making any counterclaim against the Person asserting the third party claim or demand, or any cross-complaint against any Person. Except as set forth in Section 11.4(a), no claim as to which indemnification is sought under this Agreement may be settled without the consent of the Indemnifying Party.

(c) If any Indemnified Party has a claim against the Indemnifying Party hereunder that does not involve a claim or demand being asserted against or sought to be collected from it by a third party, the Indemnified Party shall send a Claim Notice with respect to such claim to the Indemnifying Party. If the Indemnifying Party disputes such claim, such dispute will be resolved by litigation in an appropriate court of competent jurisdiction.

11.5 Time Limitations. If the Closing occurs, the Sellers will have no liability for indemnification under this Agreement with respect to any representation or warranty, or covenant or obligation to be performed and complied with prior to the Closing Date or indemnification obligation under Sections 11.1, other than those in Sections 5.1, 5.2, 5.3, 5.5, 5.10, 5.14, 8.2, 8.14, 11.1(iii), 11.1(iv) and 11.3, unless on or before the end of the 18th month following the Closing Date Buyer notifies the Sellers of a claim specifying the factual basis of that claim in reasonable detail to the extent then known by Buyer; a claim with respect to Sections 5.1, 5.2, 5.3, 5.5, 5.14, 8.2, 8.14, 11.1(iii), 11.1(iv) and 11.3, or a claim for indemnification or reimbursement not based upon any representation or warranty or any covenant or obligation to be performed and complied with prior to the Closing Date, may be made at any time; a claim with respect to Section 5.10 must be made on or before the fifth anniversary of the Closing Date. If the Closing occurs, Buyer will have no liability for indemnification under this Agreement with respect to any representation or warranty, or covenant or obligation to be performed and complied with prior to the Closing Date, other than those in Sections 6.1 and 6.2, unless on or before the end of the 18th month following the Closing Date the Sellers notify Buyer of a claim specifying the factual basis of that claim in reasonable detail to the extent then known by the Sellers; a claim with respect to Sections 6.1 or 6.2, or a claim for indemnification or reimbursement not based upon any representation or warranty or any covenant or obligation to be performed and complied with prior to the Closing Date, may be made at any time.

11.6 Limitations on Amount. Subject to the last sentence of this Section 11.6, no party will have liability for indemnification under any Section of this Article 11 (other than Sections 11.1(iii), 11.1(iv) and 11.2(ii), to which this sentence is inapplicable) until the total of all Damages with respect to such matters exceeds $5,000,000, and once such amount has been exceeded, such party will be liable for indemnification for the total of all Damages in excess of $5,000,000. Subject to the last sentence of this Section 11.6, each party’s aggregate liability under this Article 11 (other than Sections 11.1(iii), 11.1(iv) and 11.2(ii), to which this sentence is inapplicable) is limited to $106,875,000. However, this Section 11.6 will not apply to any breach of any of the parties’ covenants in this Agreement that are to be performed at or after the Closing (including Sections 8.2, 8.14, 11.1(iii), 11.1(iv) and 11.3) or any of the representations and warranties contained in Sections 5.1, 5.2, 5.3, 5.5, 5.10(a), 5.10(c), 5.10(d), 5.14, 5.21, 6.1, 6.2 or 6.4.

11.7 Exclusive Remedy. In the absence of fraud, each party’s sole and exclusive remedy with respect to any and all claims relating to the subject matter of this Agreement will be pursuant to the indemnification provisions set forth in this Article 11; provided, however, that the indemnification provisions set forth in this Article 11 do not apply to claims arising out of or relating to the Noncompetition Agreement or the Transition Services Agreement, both of which will be governed by their respective terms.

11.8 Waiver of Punitive Damages. No party will be liable to another party for any punitive damages resulting from or arising out of this Agreement or the transactions contemplated by this Agreement.

11.9 Losses Net of Insurance Proceeds. The amount of any and all Damages under this Article 11 will be determined net of any amounts actually recovered by the Indemnified Party under insurance policies, indemnities or other reimbursement arrangements with respect to such Damages.

12.1 Survival. All representations, warranties, covenants and agreements made by the parties each to the other in this Agreement or pursuant to this Agreement in any certificate, instrument or document will survive the consummation of the transactions contemplated by this Agreement for the period contemplated by Section 11.5.

12.2 Right of Offset. The Sellers have made certain representations and warranties to Buyer in this Agreement and the schedules and exhibits attached to this Agreement in connection with the acquisition of the General Partner Interest, the Limited Partner Interest, the Stellar Propane Interest and the Business. As a result of such representations, warranties and agreements, there exists the possibility that the Sellers will be liable to Buyer or be required to indemnify Buyer in accordance with this Agreement. Any obligation of Buyer to the Sellers is subject to any such liability or indemnification, and Buyer may, at its election, offset against any payment required by Buyer pursuant to this Agreement or the schedules and exhibits attached to this Agreement on the Closing Date (in the case of an offset pursuant to Section 9.14) or after the Closing (in all other cases) an amount equal to or less than the amount that such party may be liable to Buyer or may be required to pay Buyer pursuant to such indemnification.

Each party shall pay, without right of reimbursement from any other Person (including the Operating Company and Stellar Propane), the costs incurred by such party incident to the preparation and execution of this Agreement and performance of their respective obligations under this Agreement, whether or not the transactions contemplated by this Agreement are consummated, including the fees and disbursements of brokers, legal counsel, accountants and consultants employed by the respective parties in connection with the transactions contemplated by this Agreement.

14.1 Termination. This Agreement may be terminated at any time prior to the Closing:

(b) by the Sellers if the Closing has not taken place on or before December 20, 2004, provided that the right to terminate this Agreement under this Section 14.1(b) is not available to the Sellers if the willful failure of the Sellers to fulfill any obligation under this Agreement has been the cause of, or results in, the failure of the Closing to occur within such period;

(c) by Buyer if the Closing has not taken place on or before December 31, 2004, provided that the right to terminate this Agreement under this Section 14.1(c) is not available to Buyer if the failure of Buyer to fulfill any obligation under this Agreement has been the cause of, or results in, the failure of the Closing to occur within such period;

(a) In the event of a termination of this Agreement pursuant to Section 14.1(a), there will be no liability on the parties as a result thereof under this Agreement. A termination under Sections 14.1(b) or 14.1(e) by the Sellers will not prejudice any claim for Damages that the Sellers may have hereunder or in law or in equity as a consequence of any matter giving rise to a termination of this Agreement under Sections 14.1(b) or 14.1(e). A termination under Sections 14.1(c) or 14.1(f) by Buyer will not prejudice any claim for Damages that Buyer may have hereunder or in law or in equity as a consequence of any willful breach of this Agreement by the Sellers, but, except as provided in Section 9.14, in the absence of any willful breach, there will be no liability on the Sellers as a result of such termination or as a consequence of any matter giving rise to a right of termination under Sections 14.1(c) or 14.1(f). A termination under Section 14.1(e) by the Sellers will not prejudice any claim for Damages that Buyer may have hereunder or in law or in equity as a consequence of any matter giving rise to a termination of this Agreement under Section 14.1(e).

(b) A termination under Section 14.1(d) will entitle Buyer to the Termination Fee pursuant to Section 8.8.

14.3 Notice of Termination. Buyer may exercise its right of termination of this Agreement only by delivering written notice to that effect to the Sellers, provided that such notice is received by the Sellers prior to the Closing. The Sellers may exercise their right of termination of this Agreement only by delivering written notice to that effect to Buyer, provided that such notice is received by Buyer prior to the Closing.

15.1 Notices. Any notice, request, consent or communication under this Agreement will be effective only if it is in writing and (i) personally delivered, (ii) sent by certified mail, return receipt requested, postage prepaid, (iii) sent by a nationally recognized overnight delivery service, with delivery confirmed, or (iv) sent via facsimile transmission, with a copy simultaneously sent by one of the methods set forth in clauses (i) or (iii), addressed as follows:

or such other Persons or addresses as are furnished in writing by any party to the other party, and will be deemed to have been given only upon its delivery in accordance with this Section 15.1.

(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.

(b) Except as provided in Section 15.2(c), neither this Agreement nor any of the rights or duties of any party may be transferred or assigned to any Person except by a written agreement executed by all of the parties.

(c) Notwithstanding the above, Buyer may transfer and assign all or any portion of its rights under this Agreement to an Affiliate of Buyer or in connection with any merger, consolidation or conversion of Buyer or any sale of all or a significant portion of the assets of Buyer.

15.3 Modification. This 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 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 Agreement.

15.4 Waiver. Each party may, by written notice to the other party: (a) extend the time for the performance of any of the obligations or other actions of such other party under this Agreement; (b) waive any inaccuracies in the representations or warranties of such other party contained in this Agreement or in any document delivered pursuant to this Agreement; (c) waive compliance by such other party with any of the conditions or covenants of the other contained in this Agreement; or (d) waive or modify performance of any of the obligations of such other party under this Agreement. Except as provided in the preceding sentence, no action taken by or on behalf of any party, including any investigation by or on behalf of such party, will be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in this Agreement.

15.5 Entire Agreement. This Agreement, along with the Confidentiality Agreement, embodies the entire agreement between the parties with respect to the subject matter hereof and there are no agreements, representations or warranties between the parties other than those set forth or provided in this Agreement and the Confidentiality Agreement, which Confidentiality Agreement remains unaffected by this Agreement and in full force and effect in accordance with its terms. All exhibits and schedules called for by this Agreement and delivered to the parties are considered a part of this Agreement with the same force and effect as if the same had been specifically set forth in this Agreement.

15.6 Execution in Multiple Originals. This Agreement may be executed in multiple originals, each of which is deemed an original but all of which together constitute but one and the same instrument.

15.7 Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations of any party under this Agreement will not be materially and adversely affected thereby, (a) such provision will be fully severable; (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement; and (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom.

15.8 Governing Law. This Agreement is governed by and construed, interpreted and enforced in accordance with the Laws of the State of Delaware applicable to agreements made and to be performed entirely within such State, including all matters of enforcement, validity and performance. Each of the parties to this Agreement is a Delaware Person and each party to this Agreement agrees that this Agreement involves at least $100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708.

The parties have executed this Interest Purchase Agreement on the date set forth in the introductory paragraph.
