                INTRODUCTION



TRANSACTION     [_]  During 1997, Gas ("Gas" or the "Company") and Oil ("Oil")
PROPOSAL             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
ENGAGEMENT           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)


NATURE OF       [_]  A.G. Edwards relied upon and assumed, without independent
INFORMATION          verification, the accuracy and completeness of all
REVIEWED AND         financial and other information publicly available, or
PRESENTED            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.

                                        comparison purposes. Oil's projections
                                        are based on a December 31st calendar

DISCOUNTED CASH
FLOW ANALYSIS       [_]  A.G. 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:

                              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,

                    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

                    [_]  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;
