V Recommended Proposal to Board of Directors ............................ VI INTRODUCTION TRANSACTION PROPOSAL [ ] During 1997, Gas ("Gas" or the "Company") and Oil ("Oil") discussed the idea of a possible business combination by and between Gas and Oil. The series of proposed transactions involved in such combination is referred to as the "Transaction". A.G. EDWARDS' [ ] A.G. Edwards & Sons, Inc. ("A.G. Edwards") has been engaged by the Special Committee (the "Special Committee") of the Board of Directors of Gas (the "Board") to act as its financial advisor with respect to the Transaction and to issue to the Board an opinion as to the fairness, from a financial point of view, to the common unitholders of Gas who are not affiliated with Oil (the "Common Unitholders"), of the Transaction (the "Fairness Opinion"). [ ] The preparation of a fairness opinion is not susceptible to partial analyses or summary. In rendering its Fairness Opinion, A.G. Edwards will apply its judgment to a variety of complex analyses and assumptions. A.G. Edwards may give various analyses more or less weight than other analyses, and may deem various assumptions more or less probable than other assumptions. The assumptions made and the judgments applied by A.G. Edwards in rendering its opinion are not readily susceptible to description beyond that set forth in the written text of the Fairness Opinion itself. Page 1 INTRODUCTION (continued) AS PART OF ITS ENGAGEMENT, [ ] A review of the preliminary structure of the A.G. EDWARDS' ACTIVITIES Transaction; INCLUDED, BUT WERE NOT [ ] A review of Gas' and Oil's historical LIMITED TO, THE FOLLOWING: financial statements and the financial projections of Gas and Oil; [ ] A review of certain market data of Gas' Common Units and Oil's Common Stock; [ ] An analysis of the pro forma financial statements of Gas giving effect to the Transaction (as proposed); [ ] Conversations with PaineWebber regarding the nature and extent of development of the terms of the Transaction; [ ] An investigation regarding current operations and future prospects of Gas and Oil, through interviews with members of Gas' and Oil's management, respectively; [ ] A review of the industries in which Gas and Oil operate; [ ] A review of the market data for stocks of public companies in the same or similar lines of business to Gas; [ ] Analyses of the Transaction using various valuation methodologies; and [ ] Other analyses which it deemed necessary. Page 2 INTRODUCTION (continued) NATURE OF INFORMATION [ ] A.G. Edwards relied upon and assumed, without REVIEWED AND PRESENTED independent verification, the accuracy and completeness of all financial and other information publicly available, or furnished to, or otherwise discussed with A.G. Edwards including financial statements and financial projections, as provided by management of Gas and Oil and Oil's financial advisor. With respect to financial projections and other information provided to or otherwise discussed with A.G. Edwards, A.G. Edwards assumed and was advised by the senior management of Gas and Oil, respectively, that such projections and other information were reasonably prepared on a basis that reflects the best currently available estimates and judgments of the senior management of Gas and Oil, respectively, as to the expected future financial performance of Gas and Oil, in each case on a stand-alone basis and after giving effect to the Transaction. A.G. Edwards was not engaged to, and did not, independently verify the information provided and performed no audit of assets or liabilities and no independent appraisal of assets or liabilities of either Gas or Oil. A.G. Edwards has relied upon the assurances of the management of Gas and Oil that they are not aware of any facts that would make such information inaccurate or misleading. [ ] In performing its analyses, A.G. Edwards made numerous assumptions with respect to the propane distribution industry and the home heating oil distribution industry, and general business and economic conditions which are beyond the control of Gas and Oil. The analyses performed by A.G. Edwards are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by such analyses. Such analyses were prepared solely as part of A.G. Edwards' Preliminary Report to the Special Committee. [ ] This presentation is for the private use of the Special Committee and may not be distributed to any other parties without A.G. Edwards' written permission.

Page 4 Summary of Transaction Pro Forma Gas Units Outstanding (in thousands) To simplify the complexity of the steps in the Transactions, A.G. Edwards prepared a summary of its understanding. [_] There are currently 6,355 Gas units outstanding comprised of 3,832 common units, 2,396 subordinated units and 127 general partner ("GP") units. The subordinated units and GP units are assets of Oil. [_] There are currently 26,563 shares of Oil common stock outstanding, comprised of public shareholders and "insiders." The public holds 17,160 Class A shares. The "insiders" hold 9,404 shares which include 6,795 Class A shares, 11 Class B shares and 2,598 Class C shares. [_] Each shareholder of Oil will receive a certain number of units in Gas such that the implied consideration paid for each Oil share is $2.50. Additionally, each shareholder will receive a certain number of deferred partnership units ("DPUs") such that if each unit is converted at the earliest possible time, then each shareholder will receive an additional $0.65 per share in future value. [_] The publicly held 17,160 Class A shares will initially receive .1316 shares of newly created senior subordinated units (2,258 units in total) with an implied value (per PaineWebber) of $19.00/unit. This represents an implied purchase price of $2.50/share for an implied total purchase price of $42.9 million. [_] The "insiders" of Oil, who hold a total of 9,404 shares (comprised of A, B and C shares) will also initially receive an implied purchase price of $2.50/share for a total of $23.5 million. The consideration received by these shareholders will be funded by: - (1) the distribution of existing units of Gas which are currently owned by Oil [_] all of the 127 GP units owned by Oil will be given as consideration at an implied value of $22.13/unit, for a total of $2.8 million. [_] 524 of the 2,396 subordinated units owned by Oil will be given as consideration at an implied value (per PaineWebber) of $16.00/unit, for a total of $8.4 million. - (2) the distribution of newly-created units of Gas [_] to fund the remaining $12.3 million of the $23.5 million due to the Oil "insiders", Gas will issue 461 newly-created senior subordinated units and 162 newly-created GP units. The implied values for these new units are $19.00 and $22.13, respectively. Page 5 Summary of Transaction Pro Forma Gas Units Outstanding (in thousands) (continued) [_] Of the 2,396 subordinated units and 127 GP units owned by Oil, only 1,872 subordinated units will not have been used as consideration paid to the "inside" Oil shareholders. Hence, these 1,872 subordinated units will be retired by Gas. A.G. Edwards has assumed that the implied value of these units are the same as the value PaineWebber is placing on the subordinated units, which is $16.00/unit, for a total retired value of approximately $30.0 million. Page 6 SUMMARY OF GAS UNITS OUTSTANDING PRE-FINANCING ASSUMPTIONS - -------------------------------------------------------------------------------- Distributed to Oil Issued to Oil ------------------------ ----------------------- Type of Units Current Public Insiders Public Insiders Retired Pro Forma - ------------- ---------- -------- ----------- -------- ----------- --------- ----------- Common 3,832 - - - - - 3,832 Senior Subordinated - - - 2,258 461 - 2,718 Subordinated 2,396 - 524 - - (1,872) 524 DPUs - - - 587 322 - 909 General Partner (a) 127 - 127 - 162 - 289 ---------- ----------- 6,355 8,272 - -------------------------------------------------------------------------------- (a) The number of GP units issued reflects the assumption of a 6,588 common unit equity offering to refinance certain of the assumed Oil debt and a 475 common unit equity offering to finance Gas' acquisitions. Hence, the number of GP units reflected in the pro forma column do not equal 2% of the pro forma outstanding units shown above but do equal exactly 2% of the pro forma units outstanding on a post financing basis.

Edwards has compared the historical prices of PRICE PERFORMANCE Gas' and Oil's common unit/stock to an index of selected companies. [_] While Gas' unit price has remained relatively flat over the last two years, in line with the comparable index, Oil's stock price has declined significantly over this period.

Edwards reviewed the historical prices of ANALYSIS Gas' and Oil's common unit/stock and the implied historical exchange ratio. [_] Due to the price decline of Oil's common stock over the past year, the current exchange ratio, based on the current consideration of $2.50 per share and compared to the current unit/share prices of Gas and Oil ($21.375 and $1.875, respectively, as of May 15, 1998), represents a premium of 33.3% to the current market price of Oil. [GRAPH OF EXCHANGE RATIO APPEARS HERE] Factset: Daily (a) Represents the current price of Gas divided by the current price of Oil. (b) Represents the current price of Gas divided by the proposed $2.50 price in current consideration offered for each share of Oil.

Page 20 SUMMARY OBSERVATIONS (continued) PREMIUMS PAID ANALYSIS [_] An analysis of acquisitions of companies whose stock traded under $5.00 per share (pre-merger) versus companies that traded over $10.00 per share (pre-merger) indicates a substantial difference in the premiums paid. [_] Normal premiums for merger of equal transactions is -2.5% to 21.2% and normal premiums for companies whose stock trades below $5.00 per share is 13.5% to 81.0%.

Edwards reviewed and compared the relative Analysis EBITDA contribution of Gas and Oil to each firms' share of the implied combined firm value. Other measures of relative contribution analysis were non-meaningful. [_] For Gas' contribution of approximately 34% of the combined entity's EBITDA(a), it will receive approximately 41% of the implied firm value. EBITDA (b) [GRAPH APPEARS HERE] IMPLIED FIRM VALUE SEPTEMBER 30, 1998 [PIE CHART APPEARS HERE] ___________________________________ (a) For purposes of its analysis, A.G. Edwards converted Oil's historical December 31st fiscal year-end to a September 30th fiscal year-end for comparison purposes. Oil's projections are based on a December 31st calendar year end. Other measures of relative contribution analysis are non-meaningful. (b) Includes only heating oil EBITDA for Oil. (c) Implied firm value of only Oil's heating oil assets. Page 22 Updated Report to Gas' Special Committee A.G. Edwards has continued its diligence reviews of Oil and Gas, has exchanged data and views with Oil's advisor, and has further updated its earlier views and opinions of the Proposed Transaction. Certain additional observations since our last meeting include: [_] Oil continues to perform relatively better than Gas. - Additional cost reductions at Oil should add $4.4 million annually to Oil's ongoing EBITDA. - Oil continues to show improvements in its attrition rate and margin growth. YTD through 3/31/98, Oil's attrition rate was 3.3% (4.0% in January, 3.5% in February and 2.8% in March) and its margin growth was 3.7 cents. - Gas continues to experience much slower growth than originally budgeted; management has revised downward its internal growth projections and budget. - Although not yet reflected in the market, Gas is now not --- expecting to earn its $2.20 MQD until possibly 2003. - Upward revisions at Oil and downward revisions at Gas now appear to make the Proposed Transaction more accretive than historically thought; the revisions support a 1999P DCF/share of $2.73, which should easily support the proposed distribution increase from $2.20 to $2.30/unit. [_] Oil's stock price has recently improved while Gas' unit price has declined slightly. - Oil's stock price now trades at $2.0625/share vs. $1.5625/share, an increase of 32.0%. - Gas' common unit price now trades at $21.125/unit vs. $22.125/unit, a decrease of 4.5%. [_] An analysis of premiums paid in acquisitions of companies whose stocks trade under $5.00 per share supports the view that such companies generally receive a larger acquisition premium in this inefficient sector of the market. An analysis of transactions since 1996 indicated an average premium of 47.3% for companies whose stocks trade under $5.00/share (normal range: 13.5% - 81.0%) compared to an average premium of 33.2% for companies whose stocks trade over $10.00/share (normal range: 10.7% - 55.8%). Page 23 Updated Report to Gas' Special Committee (continued) [_] Although A.G. Edwards cannot presently provide any opinion regarding the Proposed Transaction, A.G. Edwards does recommend -------------- that the Special Committee communicate to Oil and Oil's financial advisor that the Committee is willing to move forward with the Proposed Transaction as outlined in the "Proposal to Special Committee, Star Gas Partners, L.P.," attached hereto in Section VI. It is our understanding that Oil respectfully disagrees with selected aspects of the proposal. [_] A.G. Edwards recommends that Joel Swanson, Esq. and Baker & Botts, LLP consult with Oil's attorneys regarding the proposed resolution of the myriad of legal issues involving tax, partnership and corporate compliance and the timing of the documentation of the Transaction in terms of definitive agreements, proxy statements and the like. Page 24 DRAFT 5/21/98 SPECIAL COMMITTEE STAR GAS PARTNERS, L.P. REVISED PROPOSAL After careful consideration of the Proposed Transaction and the views expressed by Petro and PaineWebber, the Special Committee and its advisors recommend that further refinement and evaluation of the Proposed Transaction is appropriate. Subject to further diligence and assuming no material adverse changes in Star or Petro, or in market conditions, the Special Committee proposes that the transaction contain the following safeguards for the benefit of Star's common unitholders: (A) Star Partnership Agreement. Appropriate steps should be initiated to -------------------------- amended the Star Partnership Agreement as of the closing date (assumed to be September 30, 1998) in order to include as a minimum: (A-1) authorizing the creation of new classes of senior subordinated units and deferred partnership units, which shall be junior to all present and future common units; (A-2) prohibiting the payment of any distributions to senior subordinated unitholders and to subordinated unitholders except from net distributable cash flow available from the preceding twelve months after first paying $2.30 per unit to the common unitholders for such period plus any cumulative common unit arrearages from prior period(s); and (A-3) providing a surplus available for common unit distributions equal to $1.10 per new common unit, as part of the Refinancing Transaction (described below). (B) Definitive Transaction Agreement. A draft of the definitive -------------------------------- transaction agreement should be prepared by Petro for Special Committee's careful consideration (and for future submission to the Board of Directors and common unitholders of Star and to the Board of Directors and shareholders of Petro for approval) setting forth at least the following steps: (B-1) At closing of the Transaction, Star shall be obligated to deliver to Petro's common shareholders, subject to reduction by the Revision Amount as defined in (B-4) below, the following: (A) 2,718,000 senior subordinated units of Star; (B) 524,000 subordinated units of Star; the balance must be delivered to Star free and clear for retirement; (C) 289,000 GP units of Star; and (D) 909,000 deferred partnership units of Star, convertible into senior subordinated units at 33 1/3% per annum for each year in which Petro's after-tax income contributes accretion to every Star unit in excess of [$0.50]. (B-2) The Closing shall be contingent upon the successful completion of the following (collectively, the "Refinancing Transaction"): (A) The issuance of no more than 6,588,000 new common units at a price per unit of at least $21 with a gross spread of no greater than 5.0%, and (B) The issuance of $125,000,000 new debt with an interest rate no higher than [8.5%] with a gross spread of no greater than 3.0%. The use of proceeds of the Refinancing Transaction shall be solely to refinance certain of the outstanding indebtedness assumed from Petro. (B-3) Prior to the closing of the Transaction, Petro shall represent, warrant and agree that: (A) Prior to the Refinancing Transaction, Petro shall have a balance of debt and preferred stock (at redemption value), less any cash balance in excess of such amounts required in (B-3) (B) below, of no more than $331,367,000. (B) Petro shall have a minimum cash balance of $500,000, a positive working capital balance, and a total stockholders' deficit on its balance sheet of no greater than [$__ million], all as of the Closing. (C) Petro shall set up appropriate reserves and fund all of the following transactions costs: the gross spread on the issuance of the new debt referred to in (B-2) (B); financial advisory fees and fairness opinions for Petro and Star; legal, accounting and printing fees for Petro and Star; all exchange and solicitation fees related to the retirement or redemption of Petro's debt and preferred stock; all appraisals and environmental reports; all rating agencies and bank fees; and all other out-of-pocket costs and expenses associated with the Transaction. (B-4) In the event Petro is unable or unwilling to represent and warrant each of the matters set forth in (B-3), then a Revision Amount (defined below) will be established. The Revision Amount shall reduce, on a dollar-for-dollar basis, the number of senior subordinated units of Star to be delivered to Petro's common shareholders as set forth in (B-1)(A) with each senior subordinated unit deemed to equal $19/unit. The Revision Amount shall be the difference between the net sum of monies referred to in (B-3) (A), (B) and (C) above that are transferred to Star at Closing compared to the defined or stated amounts in (B-3). If the Revision Amount is negative, then the Revision Amount will be considered to equal zero. In the event the Revision Amount exceeds [$__million], Star shall not be obligated to proceed. (B-5) Prior to the Closing of the Transaction, Petro shall not declare or distribute any cash dividends to its common shareholders.
