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)


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

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

(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.

          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.

                               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.
