SITUATION ANALYSIS

     ---------------------------------------------------------------------------
     HEATING OIL BUSINESS

     .  Petro remains the dominant force in the heating oil business, selling at
        least 3 times as much as its nearest competitor.

     .  Petro also dominates the acquisition market, acquiring a substantial
        share of all heating oil businesses sold.

     .  While the company has constantly made acquisitions over the last 5
        years, higher than expected attrition rates have resulted in little
        EBITDA growth.

     .  Operational changes which were instituted on a small scale in 1996-1997
        are expected to reduce the attrition rates over the next several years.

     .  It is anticipated that the acquisition market will continue to be strong
        as more owners approach retirement age and capital gain tax relief
        appears in sight.

SITUATION ANALYSIS

     ___________________________________________________________________________

     PETRO'S STOCK PERFORMANCE

     .  Petro's stock has been in a steady decline since 1992.

     .  Petro's stock was particularly hard hit as a result of the warm winter
        of 1996-1997.

     .  It is difficult to determine what portion of the stock's performance was
        related to Petro's financial performance and what portion is
        attributable to a lack of research and institutional following and a
        lack of comps.

     .  More importantly, one must question whether or not the operational
        improvement which is expected over the next two years will be reflected
        in a higher stock price.

     .  Furthermore, Petro's ability to pursue accretive acquisitions will
        continue to be limited by capital constraints.

SITUATION ANALYSIS

     ---------------------------------------------------------------------------

     PROPANE BUSINESS

     . Large acquisitions have been scarce. Steady stream of mega-acquisitions
       (1994-96) as over $1.5 billion of equity capital has been raised from
       1992-1996.

     . Pricing on all acquisitions has become extremely competitive.

     . Multiples for even small deals have expanded.

     . Wholesale price spike during the 1996-1997 season revealed another level
       of uncertainty, even for those companies (like Star) which profited from
       the spike.

     . Warm winter in the Northeast compounded the problem for many players.

     . The market is starting to question whether propane MLPs are really growth
       vehicles.

     . The market is also starting to question if the weather is ever normal (it
       always seems to be abnormally warm in some section, which more than
       offsets good results elsewhere).

     ---------------------------------------------------------------------------
                                                                               4

- --------------------------------------------------------------------------------

SITUATION ANALYSIS

     ---------------------------------------------------------------------------

     STAR'S STOCK PERFORMANCE

     . While Star has performed relatively well, it is difficult for the market
       to assess how much of the performance was related to inventory gains.

     . Star continues to lag behind other MLPs in terms of acquisitions, where
       Star's ability to compete is limited.

       - Management's limited propane experience limits deal flow

       - Geographic concentration limits "blend-in" opportunities

       - Larger and better capitalized players competing for the same assets

     ---------------------------------------------------------------------------
                                                                               5

     THE TRANSACTION

     ---------------------------------------------------------------------------
                                                                               6


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

THE TRANSACTION

     ---------------------------------------------------------------------------

     OVERVIEW

     . We believe that a public stock corporation is not the optimal format for
       Petro.

       - No direct comparables

       - Rapid amortization of customer lists results in no earnings

       - Perceived limited growth in heating oil industry

       - Small capitalization results in limited research coverage

     . Furthermore, the leveraged capital structure limits financial flexibility
       and growth opportunities.


     *    AS A RESULT, PETRO'S STOCK HAS NOT PERFORMED WELL AND IS NOT LIKELY TO
          ACHIEVE FULL VALUATION EVEN IF OPERATIONS IMPROVE.

     ---------------------------------------------------------------------------
                                                                               7

                                                Petroleum Heat & Power Co., Inc.
- --------------------------------------------------------------------------------

THE TRANSACTION

     ---------------------------------------------------------------------------

     IN ORDER TO ADDRESS THESE VALUATION ISSUES, PETRO SHOULD CONSIDER THE
     BENEFITS OF AN MLP STRUCTURE WHICH CAN BE ACHIEVED THROUGH A MERGER WITH
     STAR GAS

     . MLPs typically trade on a yield basis, which currently translates into a
       9-10x EBITDA multiple vs a 7-8x multiple historically at Petro.

     . The combination of the two companies would result in a sizable MLP
       (approximately $300 million implied equity value) which translates into
       better valuation and greater liquidity.

     . Concurrent with the merger, the issuance of new equity would restructure
       and delever the balance sheet.

     . The new entity would have substantially better access to capital to fund
       future growth.

     *    THE COMBINED ENTITY WOULD HAVE THE INVESTMENT STORY TO ATTRACT
          RESEARCH COVERAGE AND WOULD BENEFIT BOTH PETRO AND STAR GAS SHARE/UNIT
          HOLDERS.

     ---------------------------------------------------------------------------
                                                                               8

- --------------------------------------------------------------------------------

THE TRANSACTION

      --------------------------------------------------------------------------

      THE TRANSACTION INVOLVES TWO SEPARATE STAGES:

      --------------------------------------------------------------------------
      STAGE 1 -- THE EXCHANGE
      --------------------------------------------------------------------------

      PETRO SHAREHOLDERS EXCHANGE THEIR COMMON STOCK FOR STAR GAS MASTER LIMIT
      PARTNERSHIP UNITS AT $4.50/SHARE

      .  Shareholders who hold only Class A shares exchange into Senior
         Subordinated MLP units

      .  Senior Subordinated MLP Units valued at +/- 10% discount to Common
         Units

      .  "Inside" shareholders /(1) /exchange either into Senior Subordinated
         MLP Units or Subordinated Units plus the General Partnership Interest

      .  Senior Subordinated Units offered to "Insiders" will be capped at 3.5
         million Petro shares in order to provide adequate coverage to Star
         Common Units

      .  Subordinated Units valued at +/- 20% discount to Common Units

      .  All Senior Subordinated and Subordinated Units convert to Common Units
         after 3 years of "Earn & Pay" of $2.30 (i.e. increase the MQD on the
         Common Units)
      --------------------------------------------------------------------------

      _____________________
      (1)  Insiders for the purposes of this discussion are those individuals
           who own Class C and Class A common shares.

THE TRANSACTION
     ---------------------------------------------------------------------------

     THE TRANSACTION INVOLVES TWO SEPARATE STAGES:

     ---------------------------------------------------------------------------
     STAGE 2 -- THE RECAPITALIZATION
     ---------------------------------------------------------------------------
     APPROXIMATELY $330 MILLION OF PETRO DEBT AND PREFERRED STOCK ARE REFINANCED

     .  Existing issues will be either redeemed, exchanged, defeased or tendered
        for, depending on issue

     .  Approximately $140 million of new Star equity will be raised through the
        sale of Common Units

     .  Approximately $125 million of new, investment grade debt will be issued

                                                                              31

STEPS OF THE TRANSACTION AND TAX IMPLICATIONS

   -----------------------------------------------------------------------------

 
                         STEPS OF THE TRANSACTION    


   .  STEP ONE: Star Gas Corp. merges into Petro. Petro obtains from Star Gas
      -------- 
      Corp. the GP units of MLP and OLP and MLP subordinated units. Petro
      transfers the GP units to an LLC. The subordinated units are designated
      Senior Subordinated Units.


   .  STEP TWO: Petro transfers assets to MLP in exchange for additional Senior
      --------
      Subordinated Units so as to have a total number of Senior Subordinated
      Units equal in value to the value of the Petro Class A Common Stock held
      by the public.

   .  STEP THREE: Petro exchanges all LLC shares for an equivalent value of
      ----------
      Class C shares held by Petro insiders.


   .  STEP FOUR: The Petro insiders transfer their remaining Class A and Class C
      ---------
      Stock to the MLP in exchange for Junior Subordinated Units.


   .  STEP FIVE: OLP organized Newco. MLP transfers to OLP and OLP transfer to
      --------- 
      Newco, all Petro shares owned by the MLP, as acquired by MLP from the
      Petro insiders.


   .  STEP SIX: Newco merges with and into Petro. Class A Shares owned by the
      --------
      public are changed into Senior Subordinated Units. Class A and Class C
      shares owned by Newco are canceled. Newco shares owned by OLP are changed
      into Class A Petro shares.



                         CORRESPONDING TAX IMPLICATION

   .  Tax free.


   .  Tax free.


   .  This triggers tax at Petro measured by the value of the LLC shares in
      excess of Petro's basis in them and tax at the Petro insider level
      measured by the value of the LLC shares in excess of their basis in the
      Petro shares surrendered.
      
   .  Tax free.


   .  Tax free.


   .  This step is tax free to Newco and OLP. Petro will recognize gain equal to
      the value of the Senior Subordinated Units in excess of Petro's basis in
      them. The public shareholders will recognize gain (or loss) measured by
      the excess (or deficit) in value of the Senior Subordinated Units as
      compared to their basis in the Petro Class A Common Stock.

SITUATION ANALYSIS

     ---------------------------------------------------------------------------

     PROPANE BUSINESS

     . Pricing on all acquisitions has become extremely competitive as over $1.5
       billion of equity has come into the industry since 1994.

     . Large acquisitions have been scarce and multiples for even small deals
       have expanded.

     . Wholesale price spike during the 1996-1997 season revealed another level
       of uncertainty, even for those companies (like Star) which profited from
       the spike.

     . Warm winter in the Northeast compounded the problem for many players.

     . The market is starting to question whether propane MLPs are really growth
       vehicles, as many have failed to demonstrate internal growth.

     . The market is also starting to question if the weather is ever normal (it
       always seems to be abnormally warm in some section, which more than
       offsets good results elsewhere).

SITUATION ANALYSIS

     ---------------------------------------------------------------------------
     STAR CONTINUES TO LAG BEHIND OTHER MLPS IN TERMS OF ACQUISITIONS, WHERE
     STAR'S ABILITY TO COMPETE IS LIMITED

     .  Management's limited propane experience lowers deal flow

     .  Geographic concentration limits "blend-in" opportunities

     .  Larger and better capitalized players compete for the same assets

SITUATION ANALYSIS

     -------------------------------------------------------------------------

     HEATING OIL BUSINESS

     .  Petro remains the dominant force in the heating oil business, selling at
        least 3 times as much as its nearest competitor.

     .  Petro also dominates the acquisition market, acquiring a substantial
        share of all heating oil businesses sold.

     .  While the company has constantly made acquisitions over the last 5
        years, higher than expected attrition rates have resulted in little
        EBITDA growth.

     .  Operational changes which were instituted on a small scale in 1996-1997
        are expected to reduce the attrition rates over the next several years.

     .  It is anticipated that the acquisition market will continue to be strong
        as more owners approach retirement age and capital gain tax relief
        appears in sight.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     PETRO WILL TAKE ADVANTAGE OF FAVORABLE CONDITIONS IN THE HEATING OIL MARKET


     .  Significant competitive advantages.

        -- Industry is populated by thousands of relatively small local family
           owned businesses

        -- Higher concentration of customers than in the propane industry
           creates critical mass

        -- Sufficient financial resources to make key strategic acquisitions

        -- Management openness and ability to modify historical operating
           practices


     .  Consumer attitudes facilitate creation of a brand image.

        -- Utility product that is delivered without affirmative purchase
           decision

        -- 92% of customers do not know competitor's prices

        -- 35% of consumers do not know the name of another heating oil
           company

        -- Only 34% know the name of only one other company (no one specific
           competitor)


     .  Unique size provides significant opportunities.

        -- Engage professional management and achieve efficient organizational
           structure

        -- Enhance MIS and communication technology

        -- Operating and marketing efficiencies

     ---------------------------------------------------------------------------
                                                                              10

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     ANTICIPATED BENEFITS FROM STRATEGY

     .  Reduced operating costs and increased profitability.

     .  Growth through internal marketing.

     .  Attract new customers.

     .  Retain existing customers.

     .  Improve products and services.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     BY CREATING A BRAND IMAGE, PETRO CAN TARGET A NEW CUSTOMER BASE

     .  Consumers moving into oil heated homes.

     .  Other fuel oil dealers' dissatisfied customers.

        -- Represents 8% to 10% of market

     .  Customers of other nationally branded companies offering home delivered
        products and services.

        -- HFS real estate family of companies (Century 21, ERA, Coldwell 
           Banker)

        -- Security systems

        -- Bottled water

        -- Extermination

        -- Electricity  

        -- Lawn care


     *   CREATING A BRAND IMAGE WOULD PROVIDE PETRO THE OPPORTUNITY TO FILL THE
         VOID IN THE INDUSTRY BY BECOMING THE ONLY CONSUMER-RECOGNIZABLE HEATING
         OIL COMPANY.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     IMPROVE EXISTING CUSTOMER RETENTION


     .  Improve product thereby increasing customer satisfaction and reducing
        triggering events.

        -- Reduce oil runouts

        -- Reduce incomplete and repeat equipment repairs

        -- Provide unique on-time repairs


     .  All employees function as salesmen.


     .  Segmented and unbundled pricing.


     .  Create deeper customer relationships.

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     CREATE SEGMENTED AND UNBUNDLED PRICING

     .  Heating equipment repair and maintenance revenues lower than cost.

        -- Bundled with and subsidized by oil price

     .  Unlimited annual service contracts.

     .  Tailor unbundled pricing packages for different customer segments.

        -- Shift charges away from more visible oil to less sensitive equipment 
           repair

        -- Replace unlimited service contracts with co-pay program based on
           usage

     ---------------------------------------------------------------------------
                                                                              14

- --------------------------------------------------------------------------------

PETRO'S STRATEGY

     ---------------------------------------------------------------------------

     CREATE DEEPER CUSTOMER RELATIONSHIPS

     .  Offer rationally related products requiring similar operating expertise.

        -- Air conditioning

        -- Electric repair

        -- Plumbing


     .  Create affinity group buying benefits with cross marketing partners.

- -------------------------------------------------------------------------------

THE TRANSACTION

     --------------------------------------------------------------------------

     OVERVIEW


     .    Star's limited size relative to other comparable MLPs restricts both
          its financial flexibility and access to strategic acquisitions.


     .    We believe that a public stock corporation is not the optimal format
          for Petro.

          __   No direct comparables

          __   Rapid amortization of customer lists results in no earnings

          __   Perceived limited growth in heating oil industry

          __   Small capitalization results in limited research coverage


     .    Furthermore, Petro's leveraged capital structure also limits its
          financial flexibility and growth opportunities.

     *    AS A RESULT, STAR GAS TRADES AT A SLIGHT DISCOUNT TO ITS PEERS, WHILE
          PETRO'S STOCK HAS PERFORMED POORLY AND IS NOT LIKELY TO ACHIEVE FULL
          VALUATION EVEN IF OPERATIONS IMPROVE.

     --------------------------------------------------------------------------
                                                                              17


- ------------------------------------------------------------------------------- 
                                                        Star Gas Partners, L.P.
- -------------------------------------------------------------------------------

THE TRANSACTION
     
     --------------------------------------------------------------------------
     
     IN ORDER TO ADDRESS THESE VALUATION ISSUES, STAR GAS SHOULD CONSIDER THE
     BENEFITS OF A MERGER WITH PETRO

     .    The combination of the two companies would result in a sizable MLP
          (approximately $325 million implied equity value) which translates
          into better valuation and greater liquidity.

     .    The new entity would have substantially better access to capital to
          fund future growth.

     A MERGER WITH PETRO WILL RESPOND TO SEVERAL IMPORTANT INVESTOR ISSUES

     --------------------------------------------------------------------------
     Q:  How will the market value the mixed MLP?

     A:  Growth and ability to make distributions are the key considerations for
         valuing an MLP. The merger provides the size, business mix and
         flexibility that investors are seeking. Several diversified MLPs exist
         and perform favorably compared to their peers.

     Q:  The propane industry has low annual growth (1%-2%) versus the heating
         oil industry which is declining (2%-4%) each year. Why should Star
         enter an industry that experiences attrition?

     A:  While propane is a growth industry, there are several larger and better
         capitalized companies that are actively taking advantage of industry
         consolidation. As a result, average acquisition multiples have been bid
         up to 7x EBITDA or higher. On the other hand, Petro is the dominant
         player and leading consolidator in the heating oil market. As a result,
         Petro has averaged 10 acquisitions each year since 1992 at an average
         purchase multiple of approximately 4x EBITDA. As demonstrated below, an
         acquisition at a 4x EBITDA multiple is profitable even taking into
         account attrition:

          -  Cross marketing to new and existing customers
          -  Improving customer service
          -  Creating segmented and unbundled pricing

     Q:   Why would Petro be interested in a merger with Star Gas?

     A:   Premium to market

               -  At $3.15 per share, the exchange represents approximately a
                  20% premium to the market

          Higher valuation multiples

               -  MLPs typically trade at 10-11x EBITDA

          Enhanced growth potential due to greater access to capital

               -  Branding and internal marketing
               -  Improved productivity through capital investment
               -  Acquisitions

          Lower overall cost of capital

               -  New debt at +/- 8% vs. 12% existing debt
               -  Equity capital with limited upside

          Greater size and liquidity

               -  Implied equity market value quintuples to over $325 million

          Greater financial flexibility

               -  Extend maturities through refinancing
               -  Improved covenants due to investment grade rating

STEPS OF THE TRANSACTION AND TAX IMPLICATIONS

     --------------------------------------------------------------------------

                           Steps of the Transaction 


     .  STEP ONE: Star Gas Corp. merges into Petro. Petro obtains from Star Gas
        --------
        Corp. the GP units of MLP and OLP and MLP subordinated units. Petro
        transfers the GP units to an LLC. The subordinated units are designated
        Senior Subordinated Units.

     .  STEP TWO: Petro transfers assets to MLP in exchange for additional
        --------
        Senior Subordinated Units so as to have a total number of Senior
        Subordinated Units equal in value to the value of the Petro Class A
        Common Stock held by the public.

     .  STEP THREE: Petro exchanges all LLC shares for an equivalent value of
        ----------
        Class C shares held by Petro insiders.

     .  STEP FOUR: The Petro insiders transfer their remaining Class A and Class
        ---------
        C Stock to the MLP in exchange for Junior Subordinated Units.

     .  STEP FIVE: OLP organized Newco. MLP transfers to OLP and OLP transfer to
        ---------
        Newco, all Petro shares owned by the MLP, as acquired by MLP from the
        Petro insiders.

     .  STEP SIX: Newco merges with and into Petro. Class A Shares owned by the
        --------
        public are changed into Senior Subordinated Units. Class A and Class C
        shares owned by Newco are canceled. Newco shares owned by OLP are
        changed into Class A Petro shares.


                Corresponding Tax Implication                  

     .  Tax free.                                  
                                                    
                                               
     .  Tax free.                                  
                                               
                                               
     .  This triggers tax at Petro measured by the value of the LLC shares in
        excess of Petro's basis in them and tax at the Petro insider level
        measured by the value of the LLC shares in excess of their basis in the
        Petro shares surrendered.

     .  Tax free.                                     
                                                 
     .  Tax free.                                     
                                                 
     .  This step is tax free to Newco and OLP. Petro will recognize gain equal
        to the value of the Senior Subordinated Units in excess of Petro's basis
        in them. The public shareholders will recognize gain (or loss) measured
        by the excess (or deficit) in value of the Senior Subordinated Units as
        compared to their basis in the Petro Class A Common Stock.
