STRUCTURE

     Star Gas Partners, L.P. (the "Partnership" or the "MLP") was formed on
October 16, 1995 to acquire and operate the propane business of Star Gas
Corporation (the "Company", "Star Gas" or the "General Partner") and its parent
corporation Petroleum Heat and Power Co., Inc. ("Petro" and together with Star
Gas collectively the "Predecessor Company"). Substantially all of the
consolidated assets and liabilities of the MLP are accounted for by Star Gas
Propane, L.P. (the "Operating Partnership" or the "OLP") in which the MLP owns a
99% limited partnership interest and the Company owns a 1% general partnership
interest.

     The General Partner directs and manages all activities of the Partnership
and the Operating Partnership and is reimbursed on a monthly basis for all
direct and indirect expenses it incurs on its behalf, including the cost of
employees.

PROPOSED ACQUISITION OF PETROLEUM HEAT AND POWER CO., INC.

     On October 23, 1998, the Partnership and Petro jointly announced that they
have signed a definitive merger agreement pursuant to which Petro would become a
wholly owned subsidiary of the Partnership (the "Star Gas/Petro transaction").
This transaction would be effected through Petro shareholders exchanging their
26,562,481 shares of Petro Common Stock for 3,623,236 limited and general
partnership units of the Partnership which will be subordinated to the existing
Common Units of the Partnership.

     The Partnership currently distributes to its partners, on a quarterly
basis, all of its Available Cash, which is generally all of the cash receipts of
the Partnership less all cash disbursements, with a targeted Minimum Quarterly
Distribution ("MQD") of $0.55 per unit, or $2.20 per unit on an annualized
basis. In connection with the Star Gas/Petro transaction, the Partnership will
increase the MQD to $.575 per unit or $2.30 per unit on an annualized basis.
This increase in the MQD reflects the expectation that the transaction will be
accretive to the Partnership. The increase in the MQD will also serve to raise
the threshold needed to end the subordination period.

     Of the 3,623,236 subordinated Partnership units anticipated to be
distributed to Petro shareholders, 2,767,058 will be Senior Subordinated Units
and 856,178 will be Junior Subordinated Units and General Partnership Units. The
Senior Subordinated Units will be publicly registered and tradable (they are
expected to be listed on the New York Stock Exchange) and will be subordinated
with respect to distributions to the Partnership's Common Units. The Junior
Subordinated Units and General Partnership Units will not be registered nor
publicly tradable and will be subordinated to both the Common Units and the
Senior Subordinated Units. The Senior Subordinated Units will be exchanged with
holders of Petro's publicly traded Class A Common Stock and the Junior
Subordinated Units and General Partnership Units will be exchanged with
individuals that currently own both Petro's Class C Common Stock and Class A
Common Stock. Certain holders of Petro's Class C Common Stock will also exchange
their shares for Senior Subordinated Units.

     It is currently contemplated that 21,180,789 shares of Petro Common Stock
will be exchanged for 2,767,058 Senior Subordinated Units of Partnership.
5,381,692 shares of Petro Common Stock, held by certain individuals who
currently own Petro Class C Common Stock, including Irik P. Sevin, Chairman of
both Petro and of the General Partner of the Partnership and other members of a
group that currently controls Petro, will be exchanged for 577,205 Junior
Subordinated Units and 278,973 General Partnership Units which are economically
equivalent to Junior Subordinated Units.

PROPOSED ACQUISITION OF PETROLEUM HEAT AND POWER CO., INC. (CONTINUED)

     Pursuant to the subordination provision, distributions on the Partnership's
Senior Subordinated Units may be made only after distributions of Available Cash
on Common Units meet the MQD target. Distributions on the Partnership's Junior
Subordinated Units and General Partner Units may be made only after
distributions of Available Cash on Common Units and Senior Subordinated Units
meet the MQD. The Subordination Period will generally extend until the
Partnership earns and pays its MQD for three years. As a condition of the Star
Gas/Petro transaction, the current Partnership Agreement will be amended so that
no distribution will be paid on the Senior Subordinated Units, Junior
Subordinated Units, or the General Partner Units except to the extent Available
Cash is earned from operations.

     Like many other publicly traded master limited partnerships, the
Partnership Agreement contains a provision which provides the General Partner
with incentive distributions in excess of certain targeted amounts. Following
the Star Gas/Petro transaction, this provision will be modified so that should
there be any such incentive distributions, they will be made pro rata to the
holders of Senior Subordinated Units, Junior Subordinated Units, and General
Partner Units.

     In connection with the Star Gas/Petro transaction, the Senior Subordinated
Units, Junior Subordinated Units and General Partnership Units can earn, pro
rata, an aggregate of up to 303,000 additional Senior Subordinated Units over a
five year period for each year that Petro meets certain financial goals to a
maximum of 909,000 additional Senior Subordinated Units.

     In connection with the Star Gas/Petro transaction, the Partnership intends
to raise approximately $140 million through a public offering of Common Units
and $120 million through a public or private offering of debt securities. The
net proceeds from these offerings will be used primarily to redeem and
restructure approximately $240 million in Petro public and private debt and
preferred stock. The exact terms and timing of any such offerings will depend
upon market conditions. Any such offerings will be made only by means of a
prospectus or in transactions not requiring registration under securities laws.
The foregoing statements do not constitute an offer to sell securities.

     Petro has completed an exchange offer agreement with institutional holders
of an aggregate of $233 million or 98% of its public debt and preferred stock to
permit the redemption of such securities at the closing of the Star Gas/Petro
transaction. This agreement allows Petro to redeem its 9 3/8% Subordinated
Debentures, 10 1/8% Subordinated Notes and 12 1/4% Subordinated Debentures at
100%, 100% and 103.5% of principal amount, respectively, plus accrued interest
and also to redeem its 12 7/8% Preferred Stock at $23 per share, plus accrued
and unpaid dividends. In consideration for this early redemption right, Petro
has agreed to issue to such holders 3.37 shares of newly issued Petro Junior
Convertible Preferred Stock for each $1,000 in principal amount or liquidation
preference of such securities. Each share of Petro Junior Convertible Preferred
Stock will be exchangeable into .13064 of a Partnership Common Unit at the
conclusion of the Star Gas/Petro transaction representing a maximum of 102,773
Common Units. Petro also intends to restructure $66.2 million of privately held
notes currently outstanding.

     Petro currently has a 40.5% equity interest in the Partnership and
the General Partner is a subsidiary of Petro. After completion of the Star
Gas/Petro transaction, the Petro shareholders will own approximately 26% of the
Partnership's equity through Subordinated Units and General Partner Units. The
holders of the Partnership's Common Units (including an estimated 6.4 million
Common Units that will be sold in the Partnership's proposed $140 million public
offering) will own an aggregate of approximately 74% equity interest in the
Partnership following the completion of the transaction. In connection with the
Star Gas/Petro transaction, the General Partner of the Partnership will be a
newly organized Delaware limited liability company that will be owned by Irik
Sevin, Audrey Sevin and two entities affiliated with Wolfgang Traber, (see Part
III Item 10 - Directors and Executive Officers of the Registrant).

PROPOSED ACQUISITION OF PETROLEUM HEAT AND POWER CO., INC. (CONTINUED)

     A Special Committee of the Board of Directors of the General Partner acting
on behalf of the holders of the Common Units, negotiated the terms of the Star
Gas/Petro transaction. A.G. Edwards & Sons, Inc. was retained by the Special
Committee as independent financial advisor, and has rendered an opinion that the
Star Gas/Petro transaction is fair, from a financial point of view, to the
holders of Common Units.

     The completion of the Star Gas/Petro transaction is subject to the receipt
of regulatory approvals, the approval of the Partnership's non-affiliated Common
unitholders and non-affiliated Petro shareholders and other necessary
partnership and corporate approvals.

BUSINESS

     The Partnership is primarily engaged in the retail distribution of propane
and related equipment and supplies to residential, commercial, industrial,
agricultural and motor fuel customers. The Partnership believes that it is the
eighth largest retail propane distributor in the United States, serving
approximately 166,000 customers from 55 branch locations and 32 satellite
storage facilities in the Midwest and 19 branch locations and 14 satellite
storage facilities in the Northeast The Partnership also serves approximately 30
wholesale customers from its wholesale operation in southern Indiana.

INDUSTRY BACKGROUND

     Propane is used primarily for space heating, water heating and cooking by
residential and commercial customers, which constitute the largest portion of
the customer base. Propane is extracted from natural gas or oil wellhead gas at
processing plants or separated from crude oil during the refining process.
Propane is normally transported and stored in a liquid state under moderate
pressure or refrigeration for ease of handling in shipping and distribution.
When the pressure is released or the temperature is increased, it is usable as a
flammable gas. Propane is colorless and odorless; an odorant is added to allow
its detection. Propane is clean-burning, producing negligible amounts of
pollutants when consumed. According to the National Propane Gas Association, the
domestic retail market for propane is approximately 9.4 billion gallons
annually, with limited growth for retail demand for the product. Based upon
information contained in the Energy Information Administration's Annual Energy
Review-1995, propane accounts for approximately 3.8% of household energy
consumption in the United States.

BUSINESS STRATEGY

     The Partnership's strategy is to maximize its cash flow and profitability,
primarily through (i) acquisitions which have the potential for generating
attractive returns on investment, (ii) internal growth and (iii) controlling
operating costs. The retail propane industry is mature and experiences only
limited growth in total demand for the product. The propane industry is also
large and highly fragmented, with approximately 6,000 independently owned and
operated distributors. Given these characteristics, the Partnership's
acquisition strategy is focused on acquiring smaller to medium-sized local and
regional independent propane distributors, particularly those with a relatively
large percentage of residential customers which generate higher margins than
other types of customers and those located in the Midwest and Northeast, where
the Partnership believes it can attain higher margins than in other areas of the
United States.

     The Partnership has had access to Petro's management expertise and believes
that it will continue to have such access whether or not the Star Gas/Petro
transaction is consummated. The Partnership believes that the extensive
experience of Petro's management team in making acquisitions in the home heating
oil industry, which has many similar characteristics to the propane industry,
provides the Partnership with a competitive advantage. Additionally, the field
of potential acquisition candidates for the Partnership has been broadened
because of the ability to acquire companies with both home heating oil and
propane operations, with the Partnership retaining the propane operations and
Petro retaining

                                       5
<PAGE>
 
BUSINESS STRATEGY (CONTINUED)

the home heating oil operations or the Partnership retaining both the propane
and the home heating oil operations.  In this regard, although the Partnership
does not presently have any home heating oil operations, it may consider
acquiring or retaining such operations in the future even if the Star Gas/Petro
transaction is not completed to the extent that the Partnership is able to
identify attractive acquisition candidates in the home heating oil field.

     In order to facilitate the Partnership's acquisition strategy, the
Operating Partnership has entered into bank credit facilities which consist of a
$25.0 million acquisition facility (of which $9.0 million was outstanding as of
September 30, 1998) and a $12.0 million working capital facility (of which $4.8
million was outstanding as of September 30, 1998). In addition to borrowings
under the bank credit facilities, the Partnership may fund future acquisitions
from internal cash flow, the issuance of additional Partnership interests or
debt securities.

     While the Partnership regularly considers and evaluates acquisitions as
part of its ongoing acquisition program, the Partnership does not currently have
any present agreements or commitments with respect to any material acquisition
other than the Petro acquisition. There can be no assurance that the Partnership
will identify attractive acquisition candidates in the future or that it will be
able to acquire such candidates or obtain financing for such acquisitions on
acceptable terms. If the Partnership is able to make acquisitions, there can be
no assurance, however, that such acquisitions will not dilute earnings and
distributions to Unitholders. The General Partner has broad discretion in making
acquisitions and it is expected that the General Partner will not generally seek
Unitholder approval of acquisitions.

MARKETING AND OPERATIONS

     As of September 30, 1998, the Partnership distributed propane and provided
related services to approximately 166,000 retail customers in 13 states from 74
branch locations. The Partnership's operations are conducted under several
trademarks and trade names including: Star Gas(R), Star Gas Service(TM),
Silgas(TM), Blue Flame(R), Maingas(TM), Arrow Gas(TM), Mid-Hudson Valley
Propane(TM), Coleman Gas Service(TM), H & S Gas(TM), Isch Gas(TM), Wilhoyte L.P.
Gas(TM), Rural Natural Gas(TM), Pearl Gas(TM), Bay State-Arrow Gas(TM), Knowles
L.P. Gas(TM) and Lowe Bros. & Dad. The Partnership does not have the right to
use the trademark Star Gas(R) in the State of New York nor does the Partnership
have the right to use the Blue Flame(R) trademark in certain limited areas
outside of the Partnership's current area of operations. The marketing areas
served by the Partnership are generally rural but also include suburban areas
where natural gas is generally not available.

</TABLE>

     The distribution of propane at the retail level generally involves large
numbers of small deliveries averaging 100-150 gallons each to the majority of
the Partnership's customer base.  Homeowners or residential customers use
propane primarily for space heating, water heating, clothes drying and cooking.
Commercial customers such as motels, restaurants, retail stores and laundromats,
generally use propane for the same purposes as residential customers.
Industrial users, such as manufacturers, use propane as a heating and energy
source in the manufacturing and drying processes.  In addition, propane is used
to dry crops, cure tobacco and as a fuel source for certain motor vehicles.

MARKETING AND OPERATIONS (CONTINUED)


     During the fiscal year ended September 30, 1998, approximately 79% of the
Partnership's sales (by volume of gallons sold) were to retail customers.  Of
this amount, approximately 54% of sales by volume were to residential customers,
19% to commercial/industrial customers, 19% to agricultural customers and 8% to
motor fuel customers.  The remaining 21% of sales by volume were to wholesale
customers.  Sales to residential customers in fiscal year 1998 accounted for 58%
of the Partnership's gross profit on propane sales, reflecting the higher-margin
nature of this segment of the retail market.

     The Partnership also sells installs and services equipment related to its
propane distribution business, including heating and cooking appliances and at
some locations rents water softeners.  Typical branch locations consist of an
office, appliance showroom, warehouse and service facilities, with one or more
12,000 to 30,000 gallon bulk storage tanks located on or near the premises.
Satellite facilities typically contain only bulk storage tanks.

     Retail deliveries of propane are usually made to customers by means of the
Partnership's fleet of 280 bobtail and rack trucks.  Propane is pumped from the
bobtail truck, which generally holds 2,000 to 3,000 gallons, into a stationary
storage tank on the customer's premises.  The Partnership generally owns these
storage tanks.  The capacity of these tanks ranges from approximately 24 gallons
to 1,000 gallons.  The Partnership also delivers propane to retail customers in
portable cylinders, which typically are picked up and replenished at the
Partnership distribution locations, then returned to the retail customer.  To a
limited extent, the Partnership also delivers propane to certain end users of
propane in larger trucks known as transports (which have an average capacity of
9,000 gallons).  Users receiving transport deliveries include industrial
customers, large-scale heating accounts such as local gas utilities which use
propane as a supplemental fuel to meet peak demand requirements and large
agricultural accounts which use propane for crop drying and space heating.  "See
Item 2--Properties".

     A majority of the Partnership's residential customers receive their propane
supply pursuant to an automatic delivery system which eliminates the customer's
need to make an affirmative purchase decision.  The Partnership delivers propane
to its customers approximately five times during the year, depending upon
weather conditions and historical consumption patterns. In addition, the
Partnership provides emergency service seven days a week, 52 weeks a year.
Management believes its propane customer base to be relatively stable. In excess
of 95% of the Partnership's retail propane customers lease their tanks from the
Partnership.  In most states, certain fire safety regulations restrict the
refilling of a leased tank solely to the propane supplier that owns the tank.
Historically, the inconvenience associated with switching tanks greatly reduces
a propane customer's tendency to change their distributor.

     Profits in the retail propane business are primarily based on margins, the
cents-per-gallon difference between the purchase price and the sales price of
propane.  The Partnership generally purchases propane under supply contracts
spanning several months and in the spot market. These purchases are primarily
from natural gas processors and major oil companies. As a result, its supply
costs fluctuate with market price fluctuations.  Should wholesale propane prices
decline in the future, the Partnership's margins on its retail propane
distribution business should increase in the short-term, because retail prices
tend to change less rapidly than wholesale prices.  Should the wholesale cost of
propane increase, for similar reasons, retail margins and profitability would
likely be reduced at least for the short-term, until retail prices can be
increased.

SEASONALITY

     The retail market for propane is seasonal because it is used primarily for
heating in residential and commercial buildings.  Historically 70% - 75% of the
Partnership's retail propane volume is sold during the peak heating season from
October through March.

                                       8
<PAGE>
 
SEASONALITY (CONTINUED)


     Consequently, sales and operating profits are largely generated during the
Partnership's first and second fiscal quarters. The Partnership seeks to reserve
cash flows from the first and second fiscal quarters for distribution to holders
of its Partnership interests in the third and fourth fiscal quarters. In
addition, sales volume traditionally fluctuates from year to year in response to
variations in weather, prices and other factors.

SUPPLY

     The Partnership obtains propane from over 30 sources, all of which are
domestic or Canadian oil companies, including: Amoco Canada Marketing Corp.;
Bayway Refining Company; Domex, Inc.; Enron Gas Liquids, Inc.; Ferrell North
America; Marathon Ashland Petroleum, LLC; MarkWest Hydrocarbons; Mobil Oil
Company; Petro Canada LPG Inc.; Shell Canada Limited; Sea-3, Inc.; Shell Oil
Company; and Warren Gas Liquids, Inc. Supplies from these sources have
traditionally been readily available, although no assurance can be given that
supplies of propane will be readily available in the future.

     The Partnership supplies its Midwest retail and wholesale operations
through a combination of purchases from suppliers in Mont Belvieu, Texas and
from a number of Midwest refineries. Purchases from Mont Belvieu are typically
transported by pipeline to the Partnership's 21 million gallon underground
storage facility located in Seymour, Indiana (the "Seymour Facility") and then
delivered by truck to the Midwest branches and wholesale customers. Refinery
based purchases are transported by truck from the terminal location to the
retail operations or to wholesale customers. Typically, refinery purchases are
made pursuant to market based contracts. The Partnership may enter into forward
contracts with Mont Belvieu suppliers or refineries which call for a fixed price
for the product to be purchased based on current market conditions, with
delivery occurring at a later date. In most cases, the Partnership has entered
into similar agreements to sell this product to customers for a fixed price. In
the event that the Partnership enters into a purchase contract without a
subsequent sales contract, it is exposed to some market risk. Currently, the
Partnership does not have any contracts that if market conditions were to
change, would have a material affect on its financial statements.

     The Seymour Facility is located on the TEPPCO Partners, L.P. pipeline
system. The pipeline is connected to Mont Belvieu's storage facilities and is
one of the largest conduits of supply for the U.S. propane industry. The Seymour
Facility allows the Partnership to buy and store large quantities of propane
during periods of low demand, which generally occur during the summer months.
The General Partner believes that this ability allows the Partnership to achieve
cost savings to an extent generally not available to many of the Partnership's
competitors in its Midwest markets.

     For fiscal 1998, 28% of the Midwest volume was purchased from various Mont
Belvieu sources, 27% was purchased from three refineries in Illinois, Kentucky
and Michigan owned by Marathon Ashland Petroleum, LLC and 23% was purchased from
three refineries in Illinois and Indiana owned by the Amoco Canada Marketing
Corp.  The balance was purchased from seven separate suppliers.  The Partnership
believes that its diversification of suppliers will enable it to purchase all of
its supply needs at market prices if supplies are interrupted from any of the
sources, without a material disruption of its operations.

     Substantially all of the Partnership's propane supply for its Northeast
retail operations are purchased under annual supply contracts which generally
provide for pricing in accordance with market prices at the time of delivery.
Certain contracts provide for minimum and maximum amounts of propane to be
purchased.  During the year ended September 30, 1998, none of the Partnership's
Northeast suppliers accounted for more than 10% of the Partnership's propane
purchases.

COMPETITION

     The Partnership's retail propane business is highly competitive, however,
long-standing customer relationships are typical.  Retail propane customers
generally lease their storage tanks from their suppliers.  The lease terms and,
in most states, certain fire safety regulations restrict the refilling of a
leased tank solely to the propane supplier that owns the tank.  The
inconvenience of switching tanks minimizes a customer's tendency to switch among
suppliers of propane.

     Furthermore, the ability to compete effectively depends on the
Partnership's ability to reliably service the customer's needs and the ability
to maintain competitive prices. The Partnership believes that its superior
service capabilities and customer responsiveness differentiate it from many of
its competitors. Branch operations offer emergency service twenty-four hours per
day, seven days per week.

     Propane competes primarily with electricity, natural gas and fuel oil as an
energy source on the basis of price, availability and portability.  Propane is
generally less expensive to use than electricity for space heating, water
heating, clothes drying and cooking and competes effectively in those parts of
the country where propane is cheaper than electricity on an equivalent British
Thermal Unit basis.  Propane is generally more expensive than natural gas, but
serves as an alternative to natural gas in rural and suburban areas where
natural gas is unavailable or portability of product is required.  The expansion
of natural gas into traditional propane markets has historically been inhibited
by the capital costs required to expand distribution and pipeline systems.
Although the extension of natural gas pipelines tends to displace propane
distribution in the areas affected, the Partnership believes that new
opportunities for propane sales arise as more geographically remote areas are
developed. Although propane is similar to fuel oil in space heating and water
heating applications as well as in market demand and price, propane and fuel oil
have generally developed their own distinct geographic markets.  Because
furnaces and appliances that burn propane will not operate on fuel oil, a
conversion from one fuel to the other requires the installation of new
equipment.

     In addition to competing with alternative energy sources, the Partnership
competes with other companies engaged in the retail propane distribution
business.  Competition in the propane industry is highly fragmented and
generally occurs on a local basis with other large full-service multi-state
propane marketers, smaller local independent marketers  and farm cooperatives.
Based on industry publications, the Partnership believes that the ten largest
multi-state marketers, including the Partnership, account for less than 35% of
the total retail sales of propane in the United States, and that no single
marketer has a greater than 10% share of the total retail market in the United
States. Most of the Partnership's branches compete with five or more marketers.
The principal factors influencing competition among propane marketers are price
and service.  Each retail distribution outlet operates in its own competitive
environment as retail marketers locate in close proximity to customers to lower
the cost of providing service. The typical retail distribution outlet has an
effective marketing radius of approximately 35 miles.

EMPLOYEES

     The Partnership has no direct employees, except for certain employees of
its corporate subsidiary, Stellar Propane Service Corporation and is managed by
the General Partner pursuant to the Partnership Agreement. As of September 30,
1998, Star Gas had 624 employees providing full time services to the Operating
Partnership, of which 44 were employed by the corporate office in Stamford,
Connecticut and 580 were located in branch offices, of which 177 were
Administrative, 286 were engaged in transportation and storage and 117 were
engaged in field servicing. Approximately 78 of Star Gas' employees are
represented by six different local chapters of labor unions.

     Management believes that its relations with both its union and non-union
employees are satisfactory.

                                      10

GOVERNMENT REGULATIONS

     The Partnership is subject to various federal, state and local
environmental, health and safety laws and regulations. Generally, these laws
impose limitations on the discharge of pollutants and establish standards for
the handling of solid and hazardous wastes. These laws include the Resource
Conservation and Recovery Act, the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA"), the Clean Air Act, the Occupational
Safety and Health Act, the Emergency Planning and Community Right to Know Act,
the Clean Water Act and comparable state statues. CERCLA, also known as the
"Superfund law", imposes joint and several liability without regard to fault or
the legality of the original conduct on certain classes of persons that are
considered to have contributed to the release or threatened release of a
hazardous substance into the environment. Propane is not a hazardous substance
within the meaning of CERCLA. Such laws and regulations could result in civil or
criminal penalties in cases of non-compliance or impose liability for
remediation costs. To date, the Partnership has not been named as a party to any
litigation in which the Partnership is alleged to have violated or otherwise
incurred liability under any of the foregoing laws and regulations.

     In connection with all acquisitions of retail propane businesses that
involve the purchase of real estate, the Partnership conducts a due diligence
investigation in an attempt to determine whether any substance, other than
propane, has been sold from or stored on any such real estate prior to its
purchase.

     Such due diligence includes questioning the seller, obtaining
representations and warranties concerning the seller's compliance with
environmental laws and visual inspections of the properties, in which employees
of the General Partner, and in certain cases, independent environmental
consulting firms hired by the General Partner, look for evidence of hazardous
substances or the existence of underground storage tanks.

     National Fire Protection Association Pamphlets No. 54 and No. 58, which
establish rules and procedures governing the safe handling of propane, or
comparable regulations, have been adopted as the industry standard in all of the
states in which the Partnership operates.  In some states these laws are
administered by state agencies, and in others they are administered on a
municipal level.  With respect to the transportation of propane by truck, the
Partnership is subject to regulations promulgated under the Federal Motor
Carrier Safety Act.  These regulations cover the transportation of hazardous
materials and are administered by the United States Department of
Transportation.  The Partnership conducts ongoing training programs to help
ensure that its operations are in compliance with applicable regulations.  The
Partnership maintains various permits that are necessary to operate some of its
facilities, some of which may be material to its operations.  Management
believes that the procedures currently in effect at all of its facilities for
the handling, storage and distribution of propane are consistent with industry
standards and are in compliance in all material respects with applicable laws
and regulations.

     On August 18, 1997, the U.S. Department of Transportation ("DOT") published
its Final Rule for Continued Operation of the Present Propane Trucks ("Final
Rule").  The Final Rule is intended to address perceived risks during the
transfer of propane.  The Final Rule required certain immediate changes in
industry operating procedures, including retrofitting all propane delivery
trucks with a system that would automatically shut down the delivery vehicle's
engine and propane delivery system in the event a leak was detected.  The
Partnership, as well as the National Propane Gas Association ("NPGA") and the
propane industry in general, believe that the Final Rule cannot practicably be
complied with in its current form.  On October 15, 1997, five of the principal
multi-state propane marketers (unrelated to the Partnership) filed an action
against the DOT in the United States District Court for the Western District of
Missouri seeking to enjoin enforcement of the Final Rule.  The NPGA subsequently
filed a similar suit.  Both suits are still pending. On February 13, 1998 the
Court issued a preliminary injunction prohibiting the enforcement of the Final
Rule pending further action by the Court. In addition, Congress passed and on
October 21, 1998 the President of the United States signed the FY 1999
Transportation Appropriations Act which included a provision restricting the
authority of the Department of Transportation from enforcing certain provisions
of the Final Rule.  At this time, the Partnership cannot 

                                      11

<PAGE>
 
GOVERNMENT REGULATIONS (CONTINUED)

determine the likely outcome of the litigation or the proposed legislation or
what the ultimate long-term cost of compliance with the Final Rule will be to
the Partnership and the propane industry in general.


     Future developments, such as stricter environmental, health or safety laws
and regulations thereunder, could affect Partnership operations. It is not
anticipated that the Partnership's compliance with or liabilities under
environmental, health and safety laws and regulations, including CERCLA, will
have a material adverse effect on the Partnership.  To the extent that there are
any environmental liabilities unknown to the Partnership or environmental,
health or safety laws or regulations are made more stringent, there can be no
assurance that the Partnership's results of operations will not be materially
and adversely affected.

                              ITEM 2. PROPERTIES

     At September 30, 1998, the Partnership owned 60 of its 74 branch locations
and 36 of its 46 satellite storage facilities and leased the balance.  In
addition, the Partnership owns a 21 million gallon underground storage facility
located in Seymour, Indiana in which it stores propane for the Partnership and
third parties.  The Partnership leases its corporate headquarters in Stamford,
Connecticut, as well as office and training facilities in the Midwest.

     The transportation of propane requires specialized equipment.  The trucks
utilized for this purpose carry specialized steel tanks that maintain the
propane in a liquefied state.  At September 30, 1998, the Partnership had a
fleet of 29 tractors, 37 transport trailers, 280 bobtail and rack trucks and 302
other service and pick-up trucks.  The majority of these vehicles are owned.  In
addition, the Partnership owns 14 and leases 34 automobiles.  As of September
30, 1998, the Partnership owned approximately 237 bulk storage tanks with
typical capacities of 12,000 to 30,000 gallons, approximately 206,000 stationary
customer storage tanks with typical capacities of 24 to 1,000 gallons and
approximately 30,000 portable propane cylinders with typical capacities of 5 to
24 gallons.  The obligations of the Partnership under its borrowings are secured
by liens and mortgages on all real and personal property of the Partnership.

                    ITEM 3. LEGAL PROCEEDINGS - LITIGATION

     Propane is a flammable, combustible gas.  Serious personal injury and
property damage can occur in connection with its transportation, storage or use.
The Partnership, in the ordinary course of business, is threatened with or is
named as a defendant in various lawsuits which, among other items, seek actual
and punitive damages for product liability, personal injury and property damage.
However, the Partnership is not a party to any litigation which individually or
in the aggregate could reasonably be expected to have a material adverse effect
on the results of operations or the financial condition of the Partnership.  The
Partnership maintains liability insurance policies with insurers in such amounts
and with such coverages and deductibles as it believes is reasonable and
prudent.  However, there can be no assurance that such insurance will be
adequate to protect the Partnership from material expenses related to such
personal injury or property damage or that such levels of insurance will
continue to be available in the future at economical prices.

     As of September 30, 1998, there were approximately 175 holders of record of
the Partnership's Common Units.  There is no established public trading market
for the Partnership's 2,396,078 Subordinated Units, representing limited partner
interests ("Subordinated Units") which are all held by Star Gas Corporation.
The Partnership makes quarterly distributions of cash to its partners in an
aggregate amount equal to its Available Cash (as defined) for such quarter.
Available Cash generally means, with respect to any fiscal quarter of the
Partnership, all cash on hand at the end of such quarter, plus all additional
cash on hand as of the date of determination resulting from borrowings
subsequent to the end of such quarter, less the amount of cash reserves required
under certain lending arrangements and certain discretionary reserves
established by the General Partner for future cash requirements.  These reserves
are retained to provide for the proper conduct of the Partnership's business,
the payment of debt principal and interest and to provide funds for distribution
during the next four quarters.  The full definition of Available Cash is set
forth in the Agreement of Limited Partnership of the Partnership.  The
information concerning restrictions on distributions required in this section is
incorporated herein by reference to the Partnership's Consolidated Financial
Statements which begin on page F-1 of this Report.  Distributions of Available
Cash to the holders of the Subordinated Units are subject to the prior rights of
the Common unitholders to receive the MQD for each quarter during the
subordination period, and to receive any arrearages in the distribution of the
MQD on the Common Units for prior quarters during the subordination period.

                ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

         In analyzing the historical financial results of the Partnership, the
following matters should be considered.

         The financial results of a given year do not necessarily reflect the
full impact of that year's acquisitions. Historically, most acquisitions have
been made during the non-heating season because many sellers desire to retain
winter profits but avoid summer losses. Therefore, the effect of acquisitions
made after the heating season would not be fully reflected in the Partnership's
sales volume and operating and financial results until the following fiscal
year. In fiscal 1998, the Partnership completed six acquisitions after the
heating season, which did not positively impact fiscal 1998 results.

         Gross profit margins vary according to customer mix. For example, sales
to certain customer groups, such as residential or commercial, generally
generate higher gross profit margins than sales to other customer groups, such
as agricultural customers. Accordingly, a change in customer mix can affect
gross profit without necessarily impacting total sales.

         Because propane's primary use is for heating in residential and
commercial buildings, weather conditions have a significant impact on the
financial performance of the Partnership. Management believes that despite
year-to-year fluctuations, average temperatures have been relatively stable over
time. Nevertheless, as reflected by the unusually warm weather in fiscal 1998,
actual yearly weather conditions can vary substantially from historical
averages. Accordingly, in analyzing changes in financial performance, the
weather conditions in which the Partnership operated in any given period should
be considered.

         The following discussion reflects the results of operations and
operating data for fiscal years 1996, 1997 and 1998. For fiscal 1996, the
Predecessor Company for the period October 1, 1995 through December 20, 1995 and
the results of the MLP from December 20, 1995 through September 30, 1996 were
combined in order to facilitate an analysis of the fundamental operating data.

FISCAL YEAR ENDED SEPTEMBER 30, 1998
------------------------------------
COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30, 1997
------------------------------------------------

VOLUME

         For the year ended September 30, 1998, retail propane volume increased
4.2% or 4.0 million gallons to 98.9 million gallons, as compared to 94.9 million
gallons for fiscal 1997. This increase was due to the October 1997 acquisition
of Pearl Gas Co., and to a lesser extent, six acquisitions completed subsequent
to the end of the heating season which provided 12.1 million gallons of
additional volume. The positive impact of the fiscal 1998 acquisitions was
partially offset by temperatures which were 11.8% warmer than fiscal 1997 and
14.0% warmer than normal in the Partnership's marketing areas. For fiscal 1998,
wholesale volume declined by 12.4 million gallons or 32.3% to 26.0 million
gallons, as compared to 38.4 million gallons for fiscal 1997. This decline was
attributable to the abnormally warm winter weather and a reduction in spot sales
to certain customers.

                                      15
<PAGE>
 
SALES

         Sales decreased 17.4%, or $23.5 million, to $111.7 million for fiscal
1998, as compared to $135.2 million for fiscal 1997. This decline was primarily
due to lower retail and wholesale selling prices in response to lower propane
supply costs and weather-related reductions in volume, partially offset by the
additional sales provided by acquisitions.

COST OF SALES

         Cost of sales declined 31.5%, or $22.7 million, to $49.5 million for
fiscal 1998, as compared to $72.2 million for fiscal 1997. This decline was
attributable to lower wholesale propane supply costs and the weather-related
decrease in both retail and wholesale volumes.

GROSS PROFIT

         Gross profit declined 1.2%, or $0.7 million, to $62.2 million for
fiscal 1998, as compared to $62.9 million for fiscal 1997. This change in gross
profit was attributable to lower wholesale volume and a decline in wholesale
margins. The gross profit provided by the acquisitions partially offset the
impact of the warm weather on retail and wholesale gross profit.

DELIVERY AND BRANCH EXPENSES

         Delivery and branch expenses increased 2.2%, or $0.8 million, to $37.2
million for fiscal 1998, as compared to $36.4 million for fiscal 1997. This
increase of 2.2% was less than the 4.2% increase in retail propane volume. The
Partnership was able to partially offset $3.1 million of additional operating
costs associated with operating an approximately 12% larger business, by
reducing personnel costs, insurance expense and certain other discretionary
costs by $2.3 million, reflecting management's response to the warm winter
weather and continuing efforts to reduce operating expenses.

DEPRECIATION AND AMORTIZATION

         Depreciation and amortization expense increased $1.2 million to $11.6
million for fiscal 1998, as compared to $10.4 million for fiscal 1997. This
increase was due to the additional depreciation and amortization expenses
associated with the fiscal 1998 acquisitions and capital expenditures made
during fiscal 1998 and 1997.

GENERAL AND ADMINISTRATIVE EXPENSES

         General and administrative expenses decreased by $0.7 million to $6.1
million for fiscal 1998, as compared to $6.8 million for fiscal 1997. This
decline was primarily due to the recognition of $0.9 million of expenses in
fiscal 1997 relating to the strategic initiative, which was concluded in March
1997.

INTEREST EXPENSE, NET

         Interest expense, net of interest income, increased 13.8%, or $0.9
million to $7.9 million for fiscal 1998, as compared to $7.0 million for fiscal
1997. This increase was primarily due to an increase in long-term debt
associated with the Pearl Gas and other acquisitions.

                                      16
<PAGE>
 
NET INCOME (LOSS)

         Net income (loss) declined $3.0 million to a loss of $1.0 million for
fiscal 1998, as compared to net income of $2.0 million for fiscal 1997. This
change in net income was due to lower wholesale gross profit and to the increase
in depreciation, amortization and interest expenses associated with Pearl Gas
and six additional acquisitions.

EBITDA

         EBITDA (defined as operating income (loss) plus depreciation and
amortization less net gain (loss) of sale of equipment) declined $0.8 million or
4.0% to $18.9 million for fiscal 1998, as compared to $19.7 million for fiscal
1997. This small decline occurred in a period in which temperatures were 11.8%
warmer than fiscal 1997 and 14.0% warmer than normal. The Partnership was able
to mitigate the effects of the abnormally warm winter weather by the additional
EBITDA provided from acquisitions, an increase in retail margins and a reduction
in delivery, branch and administrative expenses. EBITDA should not be considered
as an alternative to net income (as an indicator of operating performance) or as
an alternative to cash flow (as a measure of liquidity or ability to service
debt obligations), but provides additional information for evaluating the
Partnership's ability to make the Minimum Quarterly Distribution.

FISCAL YEAR ENDED SEPTEMBER 30, 1997
------------------------------------
COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30, 1996
------------------------------------------------

VOLUME

         For the year ended September 30, 1997, retail propane volume declined
1.4 million gallons, or 1.5%, to 94.9 million gallons, as compared to 96.3
million gallons for fiscal 1996. The decline was primarily attributable to the
effect on volume of warmer temperatures experienced during the second fiscal
quarter compared to the prior year's second fiscal quarter and to customer
conservation efforts attributable to significantly higher propane selling
prices. The Partnership was able to mitigate the effects of the warmer
temperatures on retail propane volume through both internal account growth and
two acquisitions completed subsequent to the fiscal 1996 heating season. Also
favorably impacting the year-to-year comparison was an increase in sales to
agricultural customers, resulting from a return to more normal propane demand
for agricultural uses.

SALES

         For the year ended September 30, 1997, sales increased $15.6 million,
or 13.0%, to $135.2 million, as compared to $119.6 million for the year ended
September 30, 1996. The increase was due to higher selling prices in response to
an industry wide significant increase in propane supply costs experienced during
fiscal 1997.

COST OF SALES

         Cost of sales increased $13.6 million, or 23.3%, to $72.2 million for
fiscal 1997, as compared to $58.6 million for fiscal 1996. The increase was due
to higher per gallon propane supply costs.

GROSS PROFIT

         Gross profit increased $1.8 million, or 3.1%, to $62.9 million for
fiscal 1997, as compared to $61.1 million for fiscal 1996. The increase in gross
profit resulted from higher per gallon margins across all market segments which
was partially offset by the impact of slightly lower retail propane volume.

                                      17


<PAGE>
 
DELIVERY AND BRANCH EXPENSES

         Delivery and branch expenses increased $1.6 million, or 4.8%, to $36.4
million for fiscal 1997, as compared to $34.8 million for fiscal 1996. The
increase was primarily due to the additional expenses associated with the first
fiscal quarter's increase in agricultural volume, higher vehicle operating costs
due to an increase in fuel costs and higher employee benefit expenses.

DEPRECIATION AND AMORTIZATION

         Depreciation and amortization expenses increased $0.6 million, or 6.1%,
to $10.4 million for fiscal 1997, as compared to $9.8 million for fiscal 1996,
due to the impact of two acquisitions completed since March 15, 1996, the
amortization of certain deferred charges relating to the Partnership's First
Mortgage Notes and depreciation expense associated with capital expenditures
made during fiscal 1997 and 1996.

GENERAL AND ADMINISTRATIVE EXPENSES

         General and administrative expenses increased $0.3 million, or 5.6%, to
$6.8 million for fiscal 1997, as compared to $6.5 million for fiscal 1996. This
increase was primarily due to $0.9 million of one-time expenses associated with
the exploration of strategic alternatives designed to maximize unitholder value
offset by lower acquisition related expenses. On March 3, 1997, the General
Partner decided to terminate its efforts to seek a merger or possible sale of
the Partnership.

INTEREST EXPENSE, NET

         Interest expense, net of interest income, declined $0.1 million, or
2.2%, to $7.0 million for fiscal 1997, as compared to $7.1 million for fiscal
1996. This reduction was primarily due to a decline in the weighted average
borrowing rate.

INCOME TAX EXPENSE

         Income tax expense primarily represents certain state income taxes
related to the Partnership's wholly owned corporate subsidiary which conducts
non-qualifying master limited partnership business.

NET INCOME

         Net income decreased $0.6 million or 22.4%, to $2.0 million for fiscal
1997, as compared to $2.6 million for fiscal 1996. This decrease was
attributable to the increase in operating expenses, $0.9 million of one-time
costs associated with the exploration of strategic alternatives and $0.6 million
of depreciation and amortization, which was partially offset by $1.9 million
increase in gross profit.

EBITDA

         EBITDA (defined as operating income (loss) plus depreciation and
amortization less net gain (loss) on sales of equipment) decreased $0.2 million,
or 1.0%, to $19.7 million for fiscal 1997, as compared to $19.9 million for
fiscal 1996. Excluding the one-time expenses associated with the strategic
alternative, EBITDA increased $0.7 million, or 3.7%, to $20.6 million due to
improved per gallon margins across all market segments and growth in the
customer base provided by both internal marketing and acquisition efforts.
EBITDA should not be considered as an alternative to net income (as an indicator
of operating performance) or as an alternative to cash flow (as a measure of
liquidity or ability to service debt obligations) but provides additional
information for evaluating the Partnership's ability to make the Minimum
Quarterly Distribution. 

                                      18
<PAGE>
 
LIQUIDITY AND CAPITAL RESOURCES

         In fiscal 1998, net cash generated by operating activities was $9.3
million, as compared to the $19.0 million generated in fiscal 1997. This decline
of $9.7 million was attributable to a reduction in cash flows provided from
operations of $1.8 million, $5.6 million relating to changes in inventory
balances and $2.3 million relating to changes in short-term liability accounts.

         In fiscal 1998, the Partnership's cash investing activities included
$10.4 million in acquisitions, $2.1 million in growth capital expenditures and
$2.6 million in maintenance capital expenditures. In connection with the Pearl
acquisition, the Partnership acquired $1.8 million in cash, which was used to
partially fund these expenditures.

         In fiscal 1998, the Partnership raised $40.0 million from long-term
financing activities, which included $20.2 million from the sale and issue of
additional Partnership interests and $19.8 million from long-term borrowings,
net of expenses. These long-term financing activities along with $4.7 million
borrowed under the Partnership's working capital facility and $9.3 million in
cash from operating activities provided $54.0 million in funds, which were used
to acquire propane dealers with an aggregate cost of $35.7 million, to purchase
fixed assets of $4.7 million, pay distributions of $13.4 million and to increase
cash by $0.2 million.

         Based on its current cash position, bank credit availability and
expected net cash flow from operating activities, the Partnership expects to be
able to meet all of its obligations for fiscal 1999, as well as all of its other
current obligations as they become due. For fiscal 1999, the Partnership
anticipates paying interest on its First Mortgage Notes and acquisition facility
of $8.3 million, paying Limited and General Partner distributions and plans to
purchase fixed assets of approximately $2.5 million.

YEAR 2000

         The Year 2000 issue is the result of computer programs using only the
last two digits to indicate the year. If uncorrected, such computer programs
will not be able to interpret dates correctly beyond the year 1999 and, in some
cases prior to that time (as some computer experts believe), which could cause
computer system failures or other computer errors disrupting business
operations. Recognizing the potentially severe consequences of the failure to be
Year 2000 compliant, the Partnership's management has developed and implemented
a company-wide program to identify and remedy the Year 2000 issues.

         The scope of the Partnership's Year 2000 readiness program includes the
review and evaluation of the Partnership's information technology (IT) such as
hardware and software utilized in the operation of the Partnership's business.
If needed modifications and conversions are not made on a timely basis, the Year
2000 issue could cause interruption in delivering propane product to customers
or prevent the Partnership from fulfilling their service needs. The Partnership
is currently using internal and external resources to identify and correct
systems that are not Year 2000 compliant. Since the Partnership does not
internally develop software for its own use, software developed externally is
being evaluated for Year 2000 compliance. This software is being upgraded or
replaced if it is determined that it is not compliant.

         As part of this program, the Partnership's systems are being evaluated
for meeting current and future business needs and the Partnership is using this
process as an opportunity to upgrade and enhance its information systems. The
Partnership anticipates completing such upgrades and replacements as needed by
September 1999. Since many systems are being modified to provide significantly
enhanced capabilities, the Year 2000 expenses have not been nor are planned to
be specifically tracked. The Partnership expects that most of these costs will
be capitalized, as they are principally related to adding new hardware and
software applications and functionality. Other costs will continue to be
expensed as incurred. Through September 1998, the Partnership estimates that
incremental costs of approximately $0.1 million 

                                      19
<PAGE>
 
YEAR 2000 (CONTINUED)

have been incurred related to Year 2000 issues and its ongoing information
technology upgrade program. The current estimated cost to complete the upgrade
and remediation of non-compliant systems is expected to be less than $0.4
million.

         The Partnership's current estimates of the amount of time and costs
necessary to remediate and test its computer systems are based on the facts and
circumstances existing at this time. The estimates were made using assumptions
of future events including the continued availability of existing resources,
Year 2000 modification plans, implementation success by third-parties and other
factors. New developments may occur that could affect the Partnership's
estimates of the amount of time and costs necessary to modify and test its IT
and non-IT systems for Year 2000 compliance. These developments include, but are
not limited to: the availability and cost of personnel trained in this area, the
ability to locate and correct all relevant computer codes and equipment and the
planning and Year 2000 compliance success that key suppliers, vendors and
customers attain.

         In addition the Partnership has anticipated the possibility that not
all of its vendors, suppliers and other third parties will have taken the
necessary steps to adequately address their Year 2000 issues on a timely basis.
In order to minimize the impact on the Partnership, of non-compliance, the
Partnership intends to contact all key suppliers and evaluate their Year 2000
readiness. If it is determined that these parties will not be Year 2000
compliant, the Partnership will prepare a contingency plan for those suppliers
whose non-compliance could have a material effect on the Partnership's business
activities.

ACCOUNTING PRINCIPLES NOT YET ADOPTED

         The Financial Accounting Standards Board (the "FASB") issued Statement
of Financial Accounting Standards SFAS No. 131 - "Disclosure about Segments of
an Enterprise and Related Information." SFAS No. 131 requires disclosures about
segments of an enterprise and related information such as different types of
business activities and economic environments in which a business operates. This
statement is effective for fiscal years beginning after December 15, 1997.
Accordingly, the Partnership will not be required to adopt SFAS No. 131 until
fiscal 1999.

         In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". This statement is effective for fiscal
years beginning after June 15, 1999. SFAS 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities and
measure the instruments at fair value. The accounting for changes in fair value
of a derivative depends upon the intended use of such derivative. The
Partnership expects to adopt the provisions of SFAS 133 in first quarter of
fiscal 2000. The company is still evaluating the effects of SFAS 133.

         The adoption of these standards is not expected to have a material
effect on the Partnership's financial position or results of operations.

STATEMENT REGARDING FORWARD-LOOKING DISCLOSURE

         This report includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Exchange Act which
represent the Company's expectations or beliefs concerning future events that
involve risks and uncertainties, including those associated with the effect of
weather conditions on the company's financial performance, the price and supply
of propane and the ability of the Company to obtain new accounts and retain
existing accounts. All statements other than statements of historical facts
included in this Report including, without limitation, the statements under
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" and elsewhere herein, are forward-looking statements. Although the
Company believes that the expectations

reflected in such forward-looking statements are reasonable, it can give no
assurance that such expectations will prove to have been correct.

                   QUANTITATIVE AND QUALITATIVE DISCLOSURES
                               ABOUT MARKET RISK

         The Partnership is exposed to interest rate risk primarily through its
Bank Credit facilities. The Partnership utilizes these borrowings to meet its
working capital needs and also to fund the short-term needs of its acquisition
program. As of September 30, 1998, the Partnership had outstanding borrowings of
approximately $9.0 million under the acquisition Facility and $4.8 million
outstanding under the Working Capital Facility. In the event that interest rates
associated with these facilities were to increase 100 basis points, the impact
on future cash flows would be approximately $0.1 million.

PARTNERSHIP MANAGEMENT

         The General Partner manages and operates the activities of the
Partnership. Unitholders do not directly or indirectly participate in the
management or operation of the Partnership. The General Partner owes a fiduciary
duty to the Unitholders. However, the Partnership agreement contains provisions
that allow the General Partner to take into account the interest of parties
other than the Limited Partners' in resolving conflict of interest, whereby
limiting such fiduciary duties. Notwithstanding any limitation on obligations or
duties, the General Partner will be liable, as the general partner of the
Partnership, for all debts of the Partnership (to the extent not paid by the
Partnership), except to the extent that indebtedness or other obligations
incurred by the Partnership are made specifically non-recourse to the General
Partner.

         Elizabeth K. Lanier and William P. Nicoletti, who are neither officers
nor employees of the General Partner nor directors, officers or employees of any
affiliate of the General Partner, have been appointed to serve on the Audit
Committee of the General Partner's Board of Directors. The Audit Committee has
the authority to review, at the request of the General Partner, specific matters
as to which the General Partner believes there may be a conflict of interest in
order to determine if the resolution of such conflict proposed by the General
Partner is fair and reasonable to the Partnership. Any matters approved by the
Audit Committee will be conclusively deemed fair and reasonable to the
Partnership, approved by all partners of the Partnership and not a breach by the
General Partner of any duties it may owe the Partnership or the holders of
Common Units. In addition, the Audit Committee reviews the external financial
reporting of the Partnership, recommends engagement of the Partnership's
independent accountants and reviews the Partnership's procedures for internal
auditing and the adequacy of the Partnership's internal accounting controls.
With respect to the

PARTNERSHIP MANAGEMENT (CONTINUED)

additional matters, the Audit Committee may act on its own initiative to
question the General Partner and, absent the delegation of specific authority by
the entire Board of Directors, its recommendations will be advisory.

         As is commonly the case with publicly traded limited partnerships, the
Partnership does not directly employ any of the persons responsible for managing
or operating the Partnership, except for certain employees of the Partnership's
wholly-owned subsidiary, Steller Propane Service Corp. The management and
workforce of Star Gas and certain employees of Petro manage and operate the
Partnership's business as officers and employees of the General Partner and its
Affiliates. See Item 1 - Business--Employees.

     None.

UNIT OPTION PLAN

     In December 1995, the General Partner adopted the 1995 Star Gas Corporation
Unit Option Plan (the "Unit Option Plan"), which currently authorizes the
issuance of options (the "Unit Options") and Unit Appreciation Rights ("UARS")
covering up to 300,000 Subordinated Units to certain officers and employees of
the General Partner.  A total of 40,000 options were granted to key executives
in December 1995.  The Unit Options have the following characteristics:  1)
exercise price of $22 per unit, which is an estimate of the fair market value of
the Subordinated Units at the time of grant, 2) vest over five year period, 3)
exercisable after January 12, 2001, assuming the lapse of the subordination
period and 4) expire on the tenth anniversary of the date of grant.  Upon

     Section 16(a) of the Securities Exchange Act of 1934 requires the General
Partner's officers and directors, and persons who own more than 10% of a
registered class of the Partnership's equity securities, to file reports of
beneficial ownership and changes in beneficial ownership with the Securities and
Exchange Commission ("SEC").  Officers, directors and greater than 10 percent
unitholders are required by SEC regulation to furnish the General Partner with
copies of all Section 16(a) forms.

     
     Based solely on its review of the copies of such forms received by the
General Partner, or written representations from certain reporting persons that
no Form 5's were required for those persons, the General Partner believes that
during fiscal year 1998 all filing requirements applicable to its officers,
directors, and greater than 10 percent beneficial owners were met in a timely
manner.

                         INDEPENDENT AUDITORS' REPORT


The Partners of Star Gas Partners, L.P.:

          We have audited the consolidated financial statements of Star Gas
          Partners, L.P. and Subsidiary as listed in the accompanying index. In
          connection with our audits of the consolidated financial statements,
          we have also audited the financial statement schedule as listed in the
          accompanying index. These consolidated financial statements and
          financial statement schedule are the responsibility of the
          Partnership's management. Our responsibility is to express an opinion
          on these consolidated financial statements and financial statement
          schedule based on our audits.

          We conducted our audits in accordance with generally accepted auditing
          standards. Those standards require that we plan and perform the audit
          to obtain reasonable assurance about whether the financial statements
          are free of material misstatement. An audit includes examining, on a
          test basis, evidence supporting the amounts and disclosures in the
          financial statements. An audit also includes assessing the accounting
          principles used and significant estimates made by management, as well
          as evaluating the overall financial statement presentation. We believe
          that our audits provide a reasonable basis for our opinion.

          In our opinion, the consolidated financial statements referred to
          above, present fairly, in all material respects, the financial
          position of Star Gas Partners, L.P. and Subsidiary as of September 30,
          1997 and 1998 and the results of their operations and their cash flows
          for each of the years in the three-year period ended September 30,
          1998, in conformity with generally accepted accounting principles.
          Also in our opinion, the related financial statement schedule, when
          considered in relation to the basic consolidated financial statements
          taken as a whole, presents fairly, in all material respects, the
          information set forth therein.

                    STAR GAS PARTNERS, L.P. AND SUBSIDIARY

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     (IN THOUSANDS, EXCEPT PER UNIT DATA)

1)   PARTNERSHIP ORGANIZATION AND FORMATION


          Star Gas Partners, L.P. ("Star Gas Partners" or the "Partnership") was
     formed on October 16, 1995, as a Delaware limited partnership.  Star Gas
     Partners and its subsidiary, Star Gas Propane, L.P., a Delaware limited
     partnership (the "Operating Partnership" or the "OLP") were formed to
     acquire, own and operate substantially all of the propane operations and
     assets and liabilities of Star Gas Corporation ("Star Gas"), a Delaware
     corporation (and the general partner of Star Gas Partners and the Operating
     Partnership) and the propane operations and assets and liabilities of Star
     Gas' parent corporation, Petroleum Heat and Power Co., Inc., a Minnesota
     corporation ("Petro") (collectively hereinafter referred to as the
     "Predecessor Company").  The Operating Partnership is, and the Predecessor
     Company was, engaged in the marketing and distribution of propane gas and
     related appliances to retail and wholesale customers in the United States
     located principally in the Midwest and Northeast.  On December 20, 1995,
     (i) Petro conveyed all of its propane assets and related liabilities to
     Star Gas and (ii) Star Gas and its subsidiaries conveyed substantially all
     of their assets (other than $83.7 million in cash from the proceeds of the
     First Mortgage Notes and certain non-operating assets) to the Operating
     Partnership (the "Star Gas Conveyance") in exchange for general and limited
     partner interests in the Operating Partnership and the assumption by the
     Operating Partnership of substantially all of the liabilities of Star Gas
     and its subsidiaries (excluding certain income tax liabilities and certain
     other long-term obligations of Star Gas that were assumed by Petro),
     including the First Mortgage Notes and approximately $53.8 million in
     outstanding Star Gas debt due to Petro.  The net book value of the assets
     contributed by Star Gas and its subsidiaries to the Operating Partnership
     exceeded the liabilities assumed by $11.2 million.  Immediately after the
     Star Gas Conveyance, Star Gas and its subsidiaries conveyed their limited
     partner interests in the Operating Partnership to Star Gas Partners in
     exchange for an aggregate of 2.4 million Subordinated Units of limited
     partner interests in Star Gas Partners.

          Of the $83.7 million in cash retained by the General Partner, $35.8
     million was paid to Petro in satisfaction of additional indebtedness, $8.6
     million was used to redeem preferred stock of the General Partner held by
     Petro, $12.0 million was loaned to Petro, and $6.0 million was retained to
     be available to fund the General Partner's additional capital contribution
     obligation.  The remaining $21.3 million was paid to Petro as dividends.

          During fiscal 1996, Star Gas Partners completed its initial public
     offering of 2.9 million Common Units, including 0.3 million Common Units
     pursuant to an over-allotment option, at a price of $22.00 per unit.  The
     net proceeds received of $55.9 million, after deducting underwriting
     discounts, commissions and  expenses were contributed to the Operating
     Partnership and used to repay $50.3 million of debt due to Petro, which was
     assumed by the Operating Partnership in the Star Gas Conveyance and the
     Partnership used the balance of $5.6 million for general operating
     purposes.

          In order that the Partnership would commence operations with $6.2
     million of working capital on December 20, 1995, the Conveyance Agreement
     provided that the amount of debt due to Petro at closing would be adjusted
     upwards or downwards to the extent that the Star Gas Partners' net working
     capital exceeded or was less than $6.2 million.  At closing, net working
     capital was $9.7 million and $3.5 million was repaid to Petro on January
     18, 1996.

                                      F-7
<PAGE>
 
1)   PARTNERSHIP ORGANIZATION AND FORMATION (CONTINUED)


          The General Partner holds a 1.0% general partner interest in Star Gas
     Partners and a 1.0101% general partner interest in the Operating
     Partnership.  Star Gas Partners and the Operating Partnership have no
     employees, except for certain employees of its corporate subsidiary Stellar
     Propane Service Corporation.  The General Partner conducts, directs and
     manages all activities of Star Gas Partners and the Operating Partnership
     and is reimbursed on a monthly basis for all direct and indirect expenses
     it incurs on their behalf including the cost of employee wages.

          The Operating Partnership is and the Star Gas Group was, primarily
     engaged in the retail distribution of propane and related supplies and
     equipment to residential, commercial, industrial, agricultural and motor
     fuel customers, operating from 55 branches in the Midwest and 19 branches
     in the Northeast.  Propane is used primarily for space heating, water
     heating and cooking by the Partnership's residential and commercial
     customers and as a result, weather conditions have a significant impact on
     the demand for propane for both heating and agricultural purposes.
     Accordingly, actual weather conditions can vary substantially from year to
     year, significantly affecting the Partnership's financial performance.

2)   PROPOSED ACQUISITION OF PETROLEUM HEAT AND POWER CO., INC.

          On October 23, 1998, the Partnership and Petro jointly announced that
     they have signed a definitive merger agreement pursuant to which Petro
     would become a wholly-owned subsidiary of the Partnership ("the Star
     Gas/Petro transaction").  This transaction would be effected through Petro
     shareholders exchanging their 26,562,481 shares of Petro Common Stock for
     3,623,236 limited partnership units and General Partnership units of the
     Partnership which will be subordinated to the existing Common Units of the
     Partnership.

          The Partnership currently distributes to its partners, on a quarterly
     basis, all of its Available Cash, which is generally all of the cash
     receipts of the Partnership less all cash disbursements, with a targeted
     Minimum Quarterly Distribution ("MQD") of $0.55 per Unit, or $2.20 per Unit
     on an annualized basis.  In connection with the Star Gas/Petro transaction,
     the Partnership will increase the MQD to $.575 per unit or $2.30 per unit
     on an annualized basis. This increase in the MQD reflects the expectation
     that the transaction will be accretive to the Partnership.  The increase in
     the MQD will also serve to raise the threshold needed to end the
     subordination period.

          Of the 3,623,236 subordinated Partnership units anticipated to be
     distributed to Petro shareholders, 2,767,058 will be Senior Subordinated
     Units and 856,178 will be Junior Subordinated Units and General Partnership
     Units.  The Senior Subordinated Units will be publicly registered and
     tradable (they are expected to be listed on the New York Stock Exchange)
     and will be subordinated in distributions to the Partnership's Common
     Units.  The Junior Subordinated Units and General Partnership Units will
     not be registered nor publicly tradable and will be subordinated to both
     the Common Units and the Senior Subordinated Units. The Senior Subordinated
     Units will be exchanged with holders of Petro's publicly traded Class A
     Common Stock and the Junior Subordinated Units and General Partnership
     Units will be exchanged with individuals that currently own Petro's Class C
     common stock and Class A common stock.  Certain holders of Petro's Class C
     Common Stock will also exchange their shares for Senior Subordinated Units.

          It is currently contemplated that 21,180,789 shares of Petro Common
     Stock will be exchanged for 2,767,058 Senior Subordinated Units of
     Partnership.  5,381,692 shares of Petro Common Stock, held by certain
     individuals who currently own Petro Class C Common Stock, including Irik P.
     Sevin, Chairman of both Petro and of the General Partner of the Partnership
     and other members of a group that currently controls Petro, will be
     exchanged for 577,205 Junior Subordinated Units and 278,973 General
     Partnership Units which are economically equivalent to Junior Subordinated
     Units.

                                      F-8
<PAGE>
 
2)   PROPOSED ACQUISITION OF PETROLEUM HEAT AND POWER CO., INC. (CONTINUED)

          Pursuant to the partnership subordination provision, distributions on
     the Partnership's Senior Subordinated Units may be made only after
     distributions of Available Cash on Common Units meet the Minimum Quarterly
     Distribution requirement.  Distributions on the Partnership's Junior
     Subordinated Units and General Partner Units may be made only after
     distributions of Available Cash on Common Units and Senior Subordinated
     Units meet the Minimum Quarterly Distribution requirement.  The
     Subordination Period will generally extend until the Partnership earns and
     pays its MQD for three years.

          As a condition of the Star Gas/Petro transaction, the Partnership
     agreement will be amended so that no distribution will be paid on the
     Senior Subordinated Units, Junior Subordinated Units, or the General
     Partner Units except to the extent Available Cash is earned from
     operations.

          Like many other publicly traded master limited partnerships, the
     Partnership contains a provision which provides the General Partner with
     incentive distributions in excess of certain targeted amounts.  This
     provision will be modified so that should there be any such incentive
     distributions, they will be made pro rata to the holders of Senior
     Subordinated Units, Junior Subordinated Units, and General Partner Units.

          In connection with the Star Gas/Petro transaction, the Senior
     Subordinated Units, Junior Subordinated Units and General Partnership Units
     can earn, pro rata, 303,000 additional Senior Subordinated Units each year
     that Petro meets certain financial goals to a maximum of 909,000 additional
     Senior Subordinated Units.

          In connection with the Star Gas/Petro transaction, the Partnership
     intends to raise approximately $140 million through a public offering of
     Common Units and $120 million through a public or private offering of debt
     securities.  The net proceeds from these offerings will be used primarily
     to redeem approximately $240 million in Petro public and private debt and
     preferred stock.  Any such offering will be made only by means of a
     prospectus or in transactions not requiring registration under securities
     laws.

          Petro has completed an exchange offer agreement with institutional
     holders of an aggregate of $233 million or 98% of its public debt and
     preferred stock to permit the redemption of such securities at the closing
     of the Star Gas/Petro transaction.  This agreement allows Petro to redeem
     its 9 3/8% Subordinated Debentures, 10 1/8% Subordinated Notes and 12 1/4%
     Subordinated Debentures at 100%, 100% and 103.5% of principal amount,
     respectively, plus accrued interest and also to redeem its 12 7/8%
     Preferred Stock at $23 per share, plus accrued and unpaid dividends.  In
     consideration for this early redemption right, Petro has agreed to issue to
     such holders 3.37 shares of newly issued Petro Junior Convertible Preferred
     Stock for each $1,000 in principal amount or liquidation preference of such
     securities.  Each share of Petro Junior Convertible Preferred Stock will be
     exchangeable into .13064 of a Partnership Common Unit at the conclusion of
     the Star Gas/Petro transaction representing a maximum of 102,773 Common
     Units.  Petro also intends to restructure $66.2 million of privately held
     Notes currently outstanding.

          Petro currently has a 40.5% equity interest in the Partnership.  After
     completion of the Star Gas/Petro transaction, the Petro shareholders will
     own approximately 26% of the Partnership's equity through Subordinated
     Units and General Partnership Units. The holders of the Partnership's
     Common Units (including an estimated 6.4 million Common Units that will be
     sold in the Partnership's $140 million public offering) will own an
     approximate aggregate 74% equity interest in the Partnership following the
     completion of the transaction. The General Partner of the Partnership will
     be a newly organized Delaware limited liability company that will be owned
     by Irik Sevin, Audrey Sevin and two entities affiliated with Wolfgang
     Traber (see Part III Item 10 -  Directors and Executive Officers of the
     Registrant).

2)   PROPOSED ACQUISITION OF PETROLEUM HEAT AND POWER CO., INC., (CONTINUED)


          A Special Committee of the Star Board of Directors, acting on behalf
     of the Public Common Unitholders, negotiated the terms of the Star
     Gas/Petro Transaction.  A.G. Edwards & Sons, Inc. was retained by the
     Special Committee as independent financial advisor, and has rendered an
     opinion that the Star Gas/Petro Transaction is fair, from a financial point
     of view, to the public Common Unitholders.

          The completion of the Star Gas/Petro Transaction is subject to the
     receipt of regulatory approvals, the approval of Star's non-affiliated
     Common unitholders and non-affiliated Petro shareholders and other
     necessary partnership and corporate approvals.


3)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation

          The Consolidated Financial Statements for the period October 1, 1995
     through December 20, 1995 include the propane operations, assets and
     liabilities of the Predecessor Company. The Consolidated Financial
     Statements for the period December 20, 1995 through September 30, 1996 and
     for the years ended September 30, 1997 and September 30, 1998 include the
     accounts of Star Gas Partners, L.P., the Operating Partnership and its
     corporate subsidiary, Stellar Propane Service Corp., collectively referred
     to herein as (the "Partnership"). All material intercompany items and
     transactions have been eliminated in consolidation and certain
     reclassifications have been made to the 1996 financial statements to
     conform to the 1997 and 1998 presentation.

     Net Income (loss) per Limited Partner Unit

          Net income (loss) per Limited Partner Unit is computed by dividing net
     income (loss), after deducting the General Partner's 2.0% interest, by the
     weighted average number of Common Units and Subordinated Units outstanding.

     Revenue Recognition

          Sales of propane and propane appliances are recognized at the time of
     delivery of the product to the customer or at the time of sale or
     installation.  Revenue from service repairs and maintenance is recognized
     upon completion of the service provided.

     Inventories

          Inventories are stated at the lower of cost or market and are computed
     on a first-in, first-out basis.  At the dates indicated the components of
     inventory were as follows:

</TABLE>

          Substantially all of the Partnership's propane supplies for the
     Northeast retail operations are purchased under supply contracts. Certain
     of the supply contracts provide for minimum and maximum amounts of propane
     to be purchased thereunder, and provide for pricing in accordance with
     posted prices at the time of delivery or include a pricing formula that
     typically is based on current market prices. During 1996, 1997 and 1998,
     spot purchases from Mont Belvieu sources accounted for approximately 26%,
     36% and 21%, respectively, of the Partnership's total volume of propane
     purchases. In addition, the three single largest suppliers accounted for an
     aggregate of approximately 32%, 31% and 47%, respectively, of total propane
     purchases in 1996, 1997 and 1998.

                                      F-10
<PAGE>
 
3)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     The Partnership may enter into forward contracts with Mont Belvieu
     suppliers or refineries which call for a fixed price for the product to be
     purchased based on current market conditions, with delivery occurring at a
     later date. In most cases the Partnership has entered into similar
     agreements to sell this product to customers for a fixed price based on
     market conditions.  In the event that the Partnership enters into these
     types of contracts without a subsequent sale, it is exposed to some market
     risk.  Currently, the Partnership does not have any contracts that if
     market conditions were to change, would have a material affect on its
     financial statements.

     Property and Equipment

          Property and equipment are stated at cost.  Depreciation is computed
     over the estimated useful lives of the depreciable assets using the
     straight-line method.

     Intangible Assets

          The excess of cost over the fair value of net assets resulting from
     the acquisition of the Company by Petro in December 1994 is being amortized
     using the straight-line method over 25 years.  Other intangible assets,
     including covenants not to compete and customer lists are recorded at cost
     and are being amortized over their estimated useful lives, ranging from 1
     to 15 years.  Also included as intangible assets are the costs associated
     with the issuance of the Company's First Mortgage Notes which are being
     amortized under the interest method over the life of the notes.  It is the
     Partnership's policy to review intangible assets for impairment whenever
     events or changes in circumstances indicate that the carrying amount of
     such assets may not be recoverable.  The Partnership determines that the
     carrying values of intangible assets are recoverable over their remaining
     estimated lives through undiscounted future cash flow analysis. If such a
     review should indicate that the carrying amount of the intangible assets is
     not recoverable, it is the Partnership's policy to reduce the carrying
     amount of such assets to fair value.

     Customer Credit Balances

          Customer credit balances represent pre-payments received from
     customers. These payments relate primarily to a budget payment plan whereby
     customers pay their estimated annual propane gas charges on a fixed monthly
     basis and the payments made have exceeded the charges for the deliveries.

     Use of Estimates

          In accordance with generally accepted accounting principles,
     management of the Partnership has made a number of estimates and
     assumptions relating to the reporting of assets and liabilities and the
     disclosure of contingent assets and liabilities to prepare these financial
     statements.  Actual results could differ from those estimates.

     Cash Equivalents

          The Partnership considers all highly liquid investments with a
     maturity of three months or less, when purchased, to be cash equivalents.

     Income Taxes

          The Partnership is a master limited partnership.  As a result, for
     Federal income tax purposes, earnings or losses are allocated directly to
     the individual partners.  Except for the Partnership's corporate subsidiary
     which generates non-qualifying Master Limited Partnership income, no
     recognition has been given to Federal income taxes in the accompanying
     financial statements of the Partnership.  Net earnings for financial
     statement purposes may differ significantly from taxable income reportable
     to unitholders as a result of differences between the tax basis and
     financial reporting basis of assets and liabilities and due to the taxable
     income allocation requirements of the Partnership agreement.

4)   QUARTERLY DISTRIBUTION OF AVAILABLE CASH

          The Partnership distributes to its partners, on a quarterly basis, all
     of its "Available Cash."  Available Cash generally means, with respect to
     any fiscal quarter of the Partnership, all cash on hand at the end of such
     quarter, less the amount of cash reserves that are necessary or appropriate
     in the reasonable discretion of the General Partner.

          Distribution by the Partnership in an amount equal to 100% of its
     Available Cash will generally be made 98% to the Common and Subordinated
     Unitholders and 2% to the General Partner, subject to the payment of
     incentive distributions in the event Available Cash exceeds the Minimum
     Quarterly Distribution ($0.55) on all Units.  To the extent there is
     sufficient Available Cash, the holders of Common Units have the right to
     receive the Minimum Quarterly Distribution, plus any arrearage, prior to
     the distribution of Available Cash to holders of Subordinated Units. Common
     Units will not accrue arrearage for any quarter after the end of the
     Subordination Period (as defined below) and Subordinated Units will not
     accrue any arrearage with respect to distributions for any quarter.

          The first distribution commenced with the quarter ending March 31,
     1996 and was paid on May 15, 1996 to holders of record as of May 1, 1996.
     The initial distribution was $0.6225 per unit and represented a pro rata
     distribution of $0.0725 per unit for the period December 20, 1995 to
     December 31, 1995 and a quarterly distribution of $0.55 per unit for the
     three months ended March 31, 1996.  During fiscal 1996, distributions of
     $1.17 per unit (including the initial distribution) were declared and paid
     on all common, subordinated and general partnership interests. The
     aggregate amount paid for such distributions was $6.3 million during fiscal
     1996.

          During fiscal 1997, distributions of $2.20 per unit were declared and
     paid on all common, subordinated and general partnership interests.  The
     aggregate paid for such distributions was $11.8 million during fiscal 1997.

          During fiscal 1998, distributions of $2.20 per unit were declared and
     paid on all common, subordinated and general partnership interests.  The
     aggregate paid for such distributions was $13.4 million during fiscal 1998.

5)   DISTRIBUTIONS FROM OPERATING SURPLUS DURING SUBORDINATION PERIOD

          The Subordination Period will generally extend until the first day of

6)   ACQUISITIONS - PRO FORMA


          During fiscal 1996, the Partnership acquired two propane dealers with
     an aggregate cost of $2.4 million.

          During fiscal 1997, no acquisitions were completed.

          During fiscal 1998, the Partnership acquired seven unaffiliated retail
     propane dealers with an aggregate cost of $35.7 million.  The most
     significant transaction was the acquisition of the Pearl Gas Co., "Pearl"
     and is described below.

          In October 1997, pursuant to a purchase agreement, the General Partner
     purchased 240 shares of Common Stock ($100 par value) of Pearl,
     representing all of its issued and outstanding capital stock. The purchase
     price was $23.0 million and included working capital of $1.9 million and
     $0.4 of transaction expenses.  Funding for this purchase was provided by a
     $23.0 million bank acquisition facility.  Subsequent to the acquisition,
     Pearl was merged into the General Partner as part of a tax-free
     liquidation.

          The General Partner then contributed to the Partnership all of the
     assets it obtained in the stock purchase of Pearl Gas in exchange for a
     2.7% interest in the Partnership and the assumption of all liabilities
     associated with the Pearl stock including the $23.0 million of bank debt.
     The aggregate value of the interests transferred to Star Gas from the
     Partnership is $3.5 million.

          The issuance of the additional partnership interests to Star Gas was
     intended to compensate Star Gas for additional significant income tax
     liabilities which would be reflected in the consolidated federal income tax
     return of the General Partner's parent corporation, Petro.  The issuance of
     such partnership interests was approved by the Audit Committee of Star Gas
     and the Executive Committee of Petro.

          The acquisitions were accounted for under the purchase method of
     accounting.  Purchase prices have been allocated to the acquired assets and
     liabilities based on their respective fair market values on the dates of
     acquisition.  The purchase prices in excess of the fair values of net
     assets acquired were classified as intangibles in the Consolidated Balance
     Sheets. Sales and net income have been included in the Consolidated
     Statements of Operations from the respective dates of acquisition.

          Unaudited Pro forma data giving effect to the purchased businesses as
     if they had been acquired on October 1 of the year preceding the year of
     purchase is as follows:

          In December 1995, the General Partner issued $85.0 million of first
     mortgage notes (the "First Mortgage Notes") with an annual interest rate of
     8.04%.  These notes were assumed as part of the Star Gas Conveyance by the
     Operating Partnership.  In December 1997, the Operating Partnership issued
     an additional $11.0 of First Mortgage Notes with an annual interest rate of
     7.17%.  The Operating Partnership's obligations under the First Mortgage
     Note Agreements are secured, on an equal basis with the Operating
     Partnership's obligations under the Bank Credit Facilities, by a mortgage
     on substantially all of the real property and liens on substantially all of
     the operating facilities, equipment and other assets of the Operating
     Partnership.  The First Mortgage Notes will mature September 15, 2010, and
     will require semiannual prepayments, without premium on the principal
     thereof,

9)   LONG-TERM DEBT AND WORKING CAPITAL BORROWINGS (CONTINUED)

 
     beginning on March 15, 2001.  Interest is payable semiannually on March 15
     and September 15.  For the year ended September 30, 1998, the Partnership
     incurred interest expense in the amount of $7.4 million on the First
     Mortgage Notes.


          The First Mortgage Note Agreements contains various restrictive and
     affirmative covenants applicable to the Operating Partnership, including
     restrictions on the incurrence of additional indebtedness and restrictions
     on certain investments, guarantees, loans, sales of assets and other
     transactions.


          The Bank Credit Facilities consist of a $25.0 million Acquisition
     Facility and a $12.0 million Working Capital Facility.  The agreement
     governing the Bank Credit Facilities contains covenants and default
     provisions generally similar to those contained in the First Mortgage Note
     Agreements.  As of September 30, 1998, there were $9.0 million outstanding
     in borrowings under the Acquisition Facility and $4.8 million outstanding
     in borrowings under the Working Capital Facility.  The Bank Credit
     Facilities bear interest at a rate based upon, at the Partnership's option,
     either the London Interbank Offered Rate plus a margin or a Base Rate (each
     as defined in the Bank Credit Facilities).  The Partnership is required to
     pay a fee for unused commitments which amounted to $0.1 million for fiscal
     1996, $0.2 million for fiscal 1997 and $0.1 million for fiscal 1998.  For
     fiscal 1998, the weighted average interest rate on borrowings under these
     facilities was 7.46%


          The Working Capital Facility will expire June 30, 2000, but may be
     extended annually thereafter with the consent of the banks.  Borrowings
     under the Acquisition Facility will revolve until June 30, 1999, after
     which time any outstanding loans thereunder, will amortize quarterly in
     equal principal payments with a final payment due on September 30, 2002.
     However, there must be no amount outstanding under the Working Capital
     Facility for at least 30 consecutive days during each fiscal year.


          As of September 30, 1998, the annual maturities of the First Mortgage
     Notes and borrowing under the acquisition facility are set forth in the
     following table:

     borrowing agreement covenants, as amended.

 
10)  EMPLOYEE BENEFIT PLANS

          Star Gas has a 401(k) plan which covers certain eligible union and
     non-union employees.  Subject to IRS limitations, the 401(k) plan provides
     for each employee to contribute from 1.0% to 15.0% of compensation.  Star
     Gas contributes to non-union participants a matching amount up to a maximum
     of 3.0% of compensation.  Aggregate matching contributions made to the
     401(k) plan during fiscal 1996, 1997 and 1998 were $0.3 million, $0.4
     million and $0.3 million, respectively.

11)  UNIT OPTION PLAN


          On December 20, 1995, the General Partner adopted the 1995 Star Gas
     Corporation Unit Option Plan (the "Unit Option Plan"), which currently
     authorizes the issuance of options (the "Unit Options") and Unit
     Appreciation Rights ("UARS") covering up to 300,000 Subordinated Units to
     certain officers and employees of the General Partner.  A total of 40,000
     options were granted to key executives in December 1995.  The Unit Options
     have the following characteristics:  1) an exercise price of $22 per unit,
     which is an estimate of the fair market value of the Subordinated Units at
     the time of grant, 2) vest over a five year period, 3) are exercisable
     after January 1, 2001, assuming the subordination period has elapsed, and
     4) expire on the tenth anniversary of the date of grant.  Upon conversion
     of the Subordinated Units held by the General Partner and its affiliates,
     the Unit Options granted will convert to Common Unit Options.  No UARS have
     been granted pursuant to the plan.

     Long-Term Debt
     --------------


          The fair values of each of the Partnership's long-term financing
     instruments, including current maturities, are based on the amount of
     future cash flows associated with each instrument, discounted using the
     Company's current borrowing rate for similar instruments of comparable
     maturity.
