(1)  Common Unit discount rate is derived by using the appropriate rate to
     calculate a net present value equal to the 09/25/98 closing price of
     $20.75.
(2)  Terminal value is calculated as a perpetuity by dividing 2002E distribution
     by the discount rate.
(3)  The Junior Subordinated and General Partner Unit discount is determined by
     using a 20% liquidity discount for both Units and a 10% control premium for
     a General Partner Unit. The weighted average based upon pro forma Unit
     ownership is a discount of 17%.

     prior to announcement, the Star value per Subordinated Unit is the value of
     a Common Unit less a 20% liquidity discount and a 10% subordination

  (1)  Acquisition cost is based on the Pro Forma Market Value of Capitalization
       Analysis (Dain Rauscher Wessels Case), (See Petro Historical and Pro
       Forma MVE and MVC Summary on page 25) less Petro's investment in Star.
       The value of Petro's investment in Star is the closing market price of a
       Star Common Unit one day prior to announcement less a structural
       subordination discount of 15% multiplied by Petro's total implied Star
       units.

  (2)  EBITDA excludes Star Gas distributions and non-recurring expenses.

(1) Acquisition cost is based on the Pro Forma Market Value of Capitalization
    Analysis (Dain Rauscher Wessels Case), [See Petro Historical and Pro Forma
    MVE and MVC Summary on page 25] less Petro's investment in Star. The value
    of Petro's investment in Star is the closing market price of a Star Common
    Unit one day prior to announcement less a structural subordination discount
    of 15% multiplied by Petro's implied Star units.
(2) EBITDA excludes Star Gas distributions and non-recurring expenses.
