Edwards has compared the historical prices of Gas' and Oil's common unit/stock to an index of selected companies. (See Appendix E - "Exchange Ratio Analysis.") [_] 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. COMPARATIVE STOCK PRICE PERFORMANCE ---------------------------------------------------------------------------- Premium of Current Price to Price ----------------------------------------------------------------------------- Current 2 Years 1 Year 180 Days 60 Days 30 Days Price (b) Prior Prior Prior Prior Prior ----------------------------------------------------------------------------- Gas 21.94 5.1% 1.4% -2.0% -6.2% -0.3% Oil 1.63 -76.8% -45.8% -48.1% -35.0% -0.9% Composite (a) 21.96 -2.2% 6.4% -5.4% -4.4% 1.3% (a) Composite index includes the following companies: APU, CNO, HPG, EGP, NPL, SPH. (b) As of 4/22/98 [Gas Graph appears here] [Oil Graph appears here] Page 9 SUMMARY OBSERVATIONS (continued) PREMIUM PAID ANALYSIS [_] A.G. Edwards calculated the implied equity purchase price of Oil and compared the premium to Oil's current and historical prices. These premiums were compared to premiums paid in "Merger of Equals" transactions. (See Appendix D -"Premium Paid Analysis.") ------------------------------------------------------------------------- Mergers of Equals ------------------------- Oil Median Adj. Mean(a) --- ------ ------------- Premium to stock price one day prior 93.8% 9.3% 10.1% Premium to stock price one week prior 97.6% 10.0% 8.0% Premium to stock price one month prior 101.6% 6.5% 6.5% ______________________ (a) Adjusted mean excludes highest and lowest data points. Page 10 SUMMARY OBSERVATIONS (continued) EXCHANGE RATIO ANALYSIS [_] A.G. Edwards reviewed the historical prices of Gas' and Oil's common unit/stock and the implied exchange ratio and compared them to the proposed Exchange Ratio of 6.96x, which represents the proposed Oil price of $3.15/share and Gas price of $21.94/unit. (See Appendix E - "Exchange Ratio Analysis.") [_] Due to the price decline of Oil's common stock over the past year, the current exchange ratio, based upon the current unit/share prices of Gas and Oil ($21.938 and $1.625, respectively, as of April 22, 1998), represents a premium of 93.8% to the current market price of Oil. [_] Relative to current prices, the exchange ratio at $3.15 is low, however, it is in line with the average prices of the companies' equity over the past two years. [GRAPH APPEARS HERE] Page 11 SUMMARY OBSERVATIONS (continued) TRANSACTION MULTIPLE ANALYSIS [_] A.G. Edwards calculated the implied transaction multiple paid for Oil on a firm valuation basis, including costs and certain adjustments associated with the Transaction, and arrived at the following multiples: EBITDA Multiple ------ -------- 1997 Adjusted 9.1x Adjusted 1998 Budget 10.2x 1999 Projected 7.6x (See Appendix F - "Transaction Multiple Analysis.") [_] A.G. Edwards calculated the implied transaction multiple paid for Oil's existing heating oil business, excluding the valuation attributable to consolidation opportunities, and arrived at the following multiples: EBITDA Multiple ------ -------- 1997 Adjusted 6.1x Adjusted 1998 Budget 6.9x 1999 Projected 5.1x (See Appendix F - "Transaction Multiple Analysis.") [_] Oil has historically paid EBITDA multiples averaging 4.5x, with a range of 2.7x to 6.5x, for its acquisitions. [_] Gas has historically paid EBITDA multiples averaging 7.0x, with a range of 5.1x to 7.3x, for its acquisitions. Page 12 SUMMARY OBSERVATIONS (continued) RELATIVE CONTRIBUTION ANALYSIS [_] A.G. Edwards reviewed and compared the relative contribution of Gas and Oil to the pro forma combined equity based upon 1996, 1997, 1998E and 1999E EBITDA. (See Appendix G - "Relative Contribution Analysis") 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 37% of the implied firm value. [GRAPHS APPEAR 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) Firm value for all of Oil. (d) Implied firm value of only Oil's heating oil assets. Page 13 Summary Observations (continued) Accretion/Dilution Analysis [_] A.G. Edwards reviewed the distributable cash flow per unit and the related accretion, common unit coverage and total unit coverage on a pro forma basis (See Appendix H - "Accretion/Dilution Analysis"). [_] For the purpose of this analysis, A.G. Edwards had PaineWebber run its pro forma financial model for six scenarios to determine the sensitivity of certain assumptions.

Edwards calculated the implied present value of estimated unlevered free cash flows for Gas on both a stand-alone and pro forma basis (See Appendix J -- "Discounted Cash Flow Analysis"). [_] Key assumptions used in the analysis were: - Oil maintaining a flat 4.1% attrition rate; relatively no margin improvement; and completing $30 million in acquisitions each year at a 4.75x EBITDA multiple. - A 7.9% weighted average cost of capital for both cases. (See Appendix B, page 24 and Appendix K, page 57). - A 10.2x terminal EBITDA multiple, representing the current year normalized EBITDA.

Institutional ownership -investor profile -cross marketing . Potential for NYSE listing . Market liquidity Page 17 PRELIMINARY REPORT TO GAS' SPECIAL COMMITTEE [_] A.G. Edwards has initiated a full diligence review of Oil and has updated its earlier reviews of Gas, including: visits to corporate headquarters; meetings with senior operations and financial officers; review of financial statements, projections, documents and information; evaluation and revision of alternative modeling of the Transaction with Oil's financial advisor; visit to Long Island calling center and meeting with Oil's former consultant and now Vice President; meeting with A.G. Edwards' equity research analyst covering MLP's; and other relevant inquiries regarding operations, acquisitions, financings and other matters. [_] A.G. Edwards preliminary diligence and work has resulted in certain tentative conclusions and observations regarding Oil and Gas which differ from its original expectations and perceptions, including: - the anemic heating season in first quarter of calendar 1998 had a greater adverse impact on Gas than on Oil; - Oil has made strides to implement key portions of Oil's plan and the McKinsey report, including corporate identification, customer communications and implementation of a service culture, regionalization, cross marketing arrangements and rationalization of the management team; - although the El Nino affect distorted the first quarter of 1998, Oil's attrition was moderated and its pricing strategy was enhanced; and - Gas has demonstrated an ability to make propane acquisitions on a tuck-in and market expansion basis, and has already agreed to acquire a heating oil business. Page 18 PRELIMINARY REPORT TO GAS' SPECIAL COMMITTEE (continued) [_] Although A.G. Edwards does not presently have an adequate basis to form any opinion regarding the Transaction, A.G. Edwards does recommend that the Special Committee and its advisors proceed with its careful consideration and evaluation of the proposed Transaction. [_] A.G. Edwards requests 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. [_] A.G. Edwards perceives Gas as taking appropriate steps to assure procedural fairness of the Transaction including the appointment of the Special Committee, the engagement of counsel and financial advisor and the approval of the Transaction by the majority of Unitholders. The Special Committee should consider whether Oil should be obligated to take parallel action to assure procedural fairness. Page 19 PRELIMINARY REPORT TO GAS' SPECIAL COMMITTEE (continued) [_] A.G. Edwards suggests that the Special Committee's consideration of substantive fairness to the Common Unitholders should include an evaluation by the Special Committee and its advisors of: - whether Gas' partnership agreement should be amended to raise the future required minimum quarterly distribution ("MQD") for common unitholders and, if so, by how much and for what period(s); - whether the $3.15 exchange ratio should be lowered and, if so, by how much; - whether the definitive agreements should be drafted consistent with the PaineWebber models so that any excess funds expended by Oil for debt refinancings and the Transaction fees in general should automatically reduce the aggregate consideration paid by Gas for the acquisition of Oil by an equal amount; - whether cash balances should be set aside for (a) the funding of any unearned MQD to be paid to the new unitholders, (b) the funding of Gas' surplus balance to account for the addition of new outstanding units, and (c) the funding of any off- balance sheet liabilities, such as pension or tax; - whether cash payments should be required for the issuance of new general partner interests and, if so, by how much; and - such other issues suggested by the members of the Special Committee and its counsel. [_] A.G. Edwards recommends that the Special Committee communicate suggested revisions of the Transaction to management of Oil for their consideration. Page 20
