(a) Amounts Payable. On and after the Termination Date, you will not be eligible for any payments, fees, awards, benefits or compensation (including, without limitation, any amounts, fees, awards, or reimbursements paid or provided to directors of the LLC), in each such case, other than as specifically provided herein, and your participation in employee benefit plans of the Company will cease as of the Termination Date, other than as specifically provided herein. Notwithstanding the foregoing, within 5 days of the Termination Date, the Company will provide or cause to be provided to you (i) any unpaid base salary through the Termination Date; (ii) any accrued vacation through the Termination Date (up to five weeks); and (iii) any unreimbursed business expenses incurred through the Termination Date up to an amount of $10,000, subject to your presentment to the Company of appropriate documentation and provided that such business expenses would be eligible for reimbursement under the Company’s business expense reimbursement policies. Notwithstanding anything herein to the contrary, only the LLC (its successors and assigns) will have the obligation to pay you (or your estate) or to provide benefits to you (or your estate) under this Agreement, provided, however, that nothing herein shall be construed as limiting the LLC’s right to reimbursement from the Partnership. Subject to the provisions of Sections 5, 6, 7, 8, 9 and 10 of this Agreement and your not revoking the general release in Section 6 of this Agreement, and with respect to the payments under Section 2(b) of this Agreement, the Supplemental General Release required to be executed by you under Section 7 of this Agreement, and your mother not revoking her general release, you will be entitled to the payments and benefits described in Sections 2(b), (c), (d), (f) and (g) and Sections 3(c), (d) and (e) of this Agreement.

For the 13-year period beginning with the month following the five-year anniversary of the Termination Date (the “Retirement Benefit Period”), the LLC (its successors and assigns) will provide you with a monthly retirement benefit equal to $350,000 divided by 12 ($29,166.67), payable monthly on the first day of each month (the “Retirement Benefit”). In the event of your death prior to the end of the Retirement Benefit Period, the Retirement Benefit will continue to be paid to your estate for the remainder of the Retirement Benefit Period.

All of the unit appreciation rights (“UARs”) listed on Exhibit B to this Agreement are fully vested and will be payable to you on December 31, 2005, in cash, in an amount equal to any excess of the value of Senior Subordinated Units underlying each such UAR as of the close of trading on December 31, 2005 over the exercise price of the applicable UAR.

The 77,419 UARs granted to you in September, 2002 in lieu of your base salary as part of a salary deferral program implemented by the Company are fully vested and will be payable to you on the Effective Date in the form of Senior Subordinated Units and in an amount to equal $286,963.00 divided by the closing price of one Senior Subordinated Unit on March 7, 2005; provided, however, that in the event that such amount of Senior Subordinated Units exceeds 102,000, any excess amount shall be paid to you in cash, as soon as administratively practicable following the Effective Date.

Notwithstanding the foregoing or any terms in the applicable award agreements, you will not be permitted to further defer the payment date for any of your UARs.

(f) Health Benefits. The Company will provide you with medical benefits under the Company’s medical plan, as may be amended generally for all employees from time to time, during the Consulting Period (as defined in Section 3(a) of this Agreement); provided, however, that the annual premium paid by the Company on your (or your family’s) behalf will not exceed $7,000. To the extent that the annual premium exceeds $7,000, the Company will automatically deduct such premiums against the fees described in Section 3(c) of this Agreement paid immediately prior to the time the premium payment is to be paid by the Company to the medical insurer. In the event that you are entitled to medical coverage with a new employer, the Company’s obligations under this Section 2(f) will cease. Your coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, will run concurrently with the medical coverage provided hereunder and will not be provided upon the cessation of the coverage provided hereunder.

As soon as administratively practicable following the

(a) Consulting Period. For a period of five years following the Termination Date (the “Consulting Period”), you will provide services to the LLC in accordance with the terms and conditions hereinafter set forth.

(b) Duties. You will serve as a non-exclusive, senior-level consultant to the LLC. You will report only to the Chairman of the Board (the “Chairman”). It is anticipated that your consulting activities will involve capital-structure and other financial related matters, acquisition opportunities, and litigation matters affecting the Company, as reasonably requested by the Chairman or the Chief Executive Officer of the LLC and that you will perform such additional duties as mutually agreed to between you and the Chairman or the Chief Executive Officer of the LLC. You will devote an amount of time necessary to perform the consulting services reasonably requested by the Chairman hereunder at such times and places as are mutually agreeable to the parties. Notwithstanding the above, and except as otherwise agreed to by the parties, the consulting services shall be rendered telephonically when possible and performed during the course of normal business hours. The LLC acknowledges that this Agreement places no limitation on your ability to engage in other activities of your choosing, including without limitation, ownership of, employment with or consulting to any other entities; provided however, that such activities are not violative of Section 8 hereof. As an independent contractor, you will have no authority to legally bind the Company and will not hold yourself out as having such authority.

(c) Compensation. As compensation for the services to be rendered hereunder, the LLC will pay you an annual consulting fee of $395,000 payable in equal monthly installments on the first day of each calendar month during the Consulting Period. In the event of your death prior to the end of the Consulting Period, the compensation due under this Section 3(c) will continue to be paid to your estate for the remainder of the Consulting Period.

For the two-year period following the Termination Date, the LLC will reimburse you for all reasonable expenses incurred in maintaining an office to provide the consulting services under Section 3(b) of this Agreement, provided that such expenses shall in no event exceed $50,000 per year.

expenses that shall be subject to reimbursement under this Section shall consist of rent for a suitable offsite office for you and one assistant, telephone expenses, office supplies, computer costs and utilities. The LLC will also provide you with one administrative assistant at the same level as your current assistant during this two-year period.

(e) Reimbursement of Expenses. During the Consulting Period and in addition to Section 3(d) above, the LLC will, upon submission of appropriate documentation, reimburse you for reasonable business expenses for out-of-town travel expenses incurred in connection with the performance of your duties hereunder in accordance with the Company’s policies and procedures for out-of-town travel expenses in effect from time to time; provided, however, that any individual expense in excess of $500.00 and all expenses in any month in the aggregate in excess of $1,000.00 must be approved in writing by the Chairman.

(f) Termination of Consulting Period and Payments. Notwithstanding anything to the contrary in this Agreement, whether express or implied, the LLC may, at any time, terminate your consultancy and the payments and benefits to you provided for under any provision this Agreement, other than any payments and benefits otherwise due to you under the Indemnification Agreements (as such term is defined below), by giving you at least 10 days’ prior notice of the effective date of such termination, upon the unanimous vote of the members of the Board (without regard to your vote) if (i) in the course of providing consulting services hereunder, you engage in an act or omission that results in demonstrable and material economic damage to the Company, as determined by a final judicial or arbitral decision from which no appeal may be taken or (ii) you initiate a challenge to the enforceability or legality of any provision of the voting trust agreement entered into between you, Joseph Cavanaugh and Stephen Russell, dated as of March 7, 2005 (the “Voting Trust Agreement”) (each of (i) and (ii), a “Termination Event”); provided however, that any statements made as required by law, a court of competent jurisdiction, any recognized subpoena power or other legal process shall be deemed not to be a challenge to the enforceability or legality of any provision of the Voting Trust Agreement. The Board may terminate your consultancy and the payments and benefits to you provided for under any provision of this Agreement, other than any payments and benefits otherwise due to you under the Indemnification Agreements (as such term is defined below), pursuant to Section 3(f)(i) only if the Board (x) notifies you hereunder of its intent to terminate you within 90 days of the Board’s discovery of the occurrence of any of such Termination Event and (y) gives you an opportunity, within 15 days after the expiration of the cure period described in Section 3(f)(z) of this Agreement, provided that the underlying circumstances giving rise to such event remains uncured after expiration of the 30 day period, to be heard with counsel at a special Board meeting in connection with the LLC’s termination of the Consulting Period and (z) gives you an opportunity to cure the underlying circumstances giving rise to such Termination Events within thirty (30) business days after the date of such meeting.

1. I hereby sign this Supplemental General Release for and in consideration of the payments and benefits previously paid or provided to me or to be made or provided to me and the promises set forth herein and in the letter agreement, dated March 7, 2005 between Star Gas Partners, L.P., Star Gas LLC (the “LLC”), and their affiliates, successors and assigns (collectively, the “Company”) and me (the “Letter Agreement”). I further acknowledge that the payments, benefits and other entitlements under the Letter Agreement exceed any payment, benefit, or other thing of value to which I might otherwise be entitled under any policy, plan or procedure of the Company or any prior agreement between me and the Company.

2. Supplemental General Release. (a) For and in consideration of the payments and benefits previously paid or provided to me, payments to be made to me under the Letter Agreement, and other good and valuable consideration, I, for myself and for my heirs, dependents, executors, administrators, trustees, legal representatives and assigns (collectively referred to as “Releasors”), hereby forever release, waive and discharge (i) the Company, its and their employee benefit and/or pension plans or funds, insurers, successors and assigns, (ii) all past, present and/or future officers, directors, trustees, members, partners, employees, fiduciaries, administrators, controlling persons and successors and assigns of the foregoing, and (iii) all of the past, present and/or future agents, representatives and attorneys (including outside legal counsel) of any of the persons or entities described in (i) or (ii) in this Section 2(a) and any of its and their successors and assigns in all cases whether acting as agents for or with respect to the Company or in their individual capacities (collectively referred to as “Releasees”), from any and all claims, demands, causes of action, fees and liabilities of any kind whatsoever, whether known or unknown, which Releasors ever had or now have against Releasees by reason of any actual or alleged act, omission, transaction, practice, policy, procedure, conduct, occurrence, or other matter up to, and including, the date of my execution of this Supplemental General Release, including without limitation, those in connection with, or in any way related to or arising out of, any of my positions with the Company or termination thereof.

(b) Without limiting the generality of the foregoing, this Supplemental General Release is intended and will release the Releasees from any and all claims, whether known or unknown, which Releasors ever had or now have against the Releasees including, but not limited to, (i) any claim of discrimination or retaliation under the Age Discrimination in Employment Act (“ADEA”) 29 U.S.C. Section 621 et seq., Title VII of the Civil Rights Act, the Americans with Disabilities Act, the Employee Retirement Income Security Act of 1974, as amended, or the Family and Medical Leave Act; (ii) any claim under the New York State Human Rights Law and the New York City Administrative Code; (iii) any other claim (whether based on federal, state or

local law or ordinance statutory or decisional) relating to or arising out of my service with the Company, the terms and conditions of such service, the termination of such service and/or any of the events relating directly or indirectly to or surrounding the termination of such service, and/or any of the events relating directly or indirectly to or surrounding the termination of such service, including, but not limited to, breach of contract (express or implied), tort, wrongful discharge, detrimental reliance, defamation, emotional distress or compensatory or punitive damages; and (iv) any claim for attorney’s fees, costs, disbursements and the like related to any claims described in Sections 2(b)(i), 2(b)(ii) or 2(b)(iii) above.

(c) I agree that I will not, from any source or proceeding, seek or accept any award or settlement with respect to any claim or right covered by Sections 2(a) or (b) above. I further agree that I will not, at any time hereafter, commence, maintain, prosecute, participate in as a party, permit to be filed by any other person on my behalf (to the extent it is within my control or permitted by law), or assist in the commencement or prosecution of as an advisor, witness (unless compelled by legal process or court order) or otherwise, any action or proceeding of any kind, judicial or administrative (on my own behalf, on behalf of any other person and/or on behalf of or as a member of any alleged class of persons) in any court, agency, investigative or administrative body against any Releasee with respect to any actual or alleged act, omission, transaction, practice, conduct, occurrence or any other matter up to and including the date of my execution of this Supplemental General Release which I released pursuant to Sections 2(a) or (b) above. I further represent that, as of the date I sign this Supplemental General Release, I have not taken any action encompassed by this Section 2(c). If, notwithstanding the foregoing promises, I violate this Section 2(c), I will indemnify and hold harmless Releasees from and against any and all demands, assessments, judgments, costs, damages, losses and liabilities and attorneys’ fees and other expenses which result from, or are incidents to, such violation. Notwithstanding anything herein to the contrary, this Section 2(c) will not apply to any claims that I may have under the ADEA and will not apply to the portion of the release provided for in Sections 2(a) or (b) relating to the ADEA.

(d) The sole matters to which the release and covenants in this Section 2 do not apply are: (i) my rights under the Letter Agreement, my rights under the Indemnification Agreements, including my rights of indemnification and related rights (except as provided in Section 11 of the Letter Agreement) or otherwise with regard to my service as an officer or director of the Company (if any) and my rights under any D&O policy maintained by or for the benefit of the Company or its employees or directors at any time during or after the course of my employment with the Company (if any); (ii) my rights to contribution (if any) with regard to my service as an officer and director of the Company; and (iii) my rights as a unitholder of the Company (if any). All capitalized terms in this Section 2(d) shall have the meaning ascribed to them in the Letter Agreement.

The interpretation of this Supplemental General Release will be governed and construed in accordance with the laws of the State of New York, without reference to principles of conflict of laws. If any provisions of this Supplemental General Release will be declared to be invalid or unenforceable, in whole or in part, such invalidity or unenforceability will not affect the remaining provisions hereof which will remain in full force and effect.
