Item 1.  Change in Control of Registrant

         None.

Item 2.  Acquisition or Disposition of Assets        

 
  On March 26, 1999, Star Gas Partners, L.P. acquired Petroleum Heat and Power
Co. Inc in a four part transaction. Each part of the transaction closed at
the same time. The four principal parts of the transaction are described below.
 
Acquisition of Petro
 
  On October 22, 1998, Petro, Star Gas Partners, Star Gas Propane L.P. (a
99%-owned subsidiary of Star Gas Partners) and a wholly-owned subsidiary of Star
Gas Propane, executed a merger agreement. The parties entered into an amended
and restated merger agreement on February 3, 1999 to reflect changes in the
transaction. Under the merger agreement, upon the completion of the transaction
on March 26, 1999, the subsidiary was merged with and into Petro, with Petro
surviving the merger as a wholly-owned indirect subsidiary of Star Gas Propane.
As a result of the merger:

 
  .  each outstanding share of Petro Class A common stock, par value $0.10
     per share, and Petro Class C common stock, par value $0.10 per share,
     other than shares that have been exchanged in the Exchange, was
     converted into 0.11758 senior subordinated units;
 
  .  each outstanding share of Petro junior convertible preferred stock was
     converted into 0.13064 common units; and
 
  .  each outstanding share of Petro Series C exchangeable preferred stock
     due 2009 was converted into the right to receive $10.69 in cash per
     share plus accrued and unpaid dividends except for an aggregate of
     505,000 shares of Series C preferred stock that were converted into an
     aggregate of 400,531 common units.
 
  There are 11,228 shares of Petro Class B common stock, par value $0.10 per
share, representing less than 0.01% of the issued and outstanding shares of
Petro common stock, which remained outstanding following the completion of the
transaction.
 
  The "exchange" occured immediately prior to the merger and was comprised of
the following elements.
 
     (a) Holders of Petro common stock, consisting of Irik P. Sevin, Audrey L.
  Sevin, Hanseatic Corp. and Hanseatic Americas Inc., who are referred to as
  the "LLC Owners," formed Star Gas LLC, to which they contributed a portion
  of their shares of Petro common stock in exchange for all of the limited
  liability company interests in Star Gas LLC. Star Gas LLC contributed those
  shares to Star Gas Partners in exchange for general partner units. In
  addition, the LLC Owners contributed their remaining shares of Petro common
  stock to Star Gas Partners in exchange for junior subordinated units.
 
     (b) Other Petro common stockholders who are affiliates of Petro contributed
  shares of Petro common stock to Star Gas Partners in exchange for Star Gas
  Partners senior subordinated units.
 
Financings and Refinancings
 
  An integral element of the transaction was the refinancing of Petro's
outstanding debt and preferred stock to substantially reduce Petro's ongoing
borrowing costs. This refinancing was accomplished through several related
transactions, which closed at the same time as the closing of the transaction.
 
  To accomplish this refinancing, Star Gas Partners offered and sold to the
public 8.7 million common units in the equity offering, the net proceeds of
which were approximately $116.1 million. Petro offered and sold, in a private
placement, $90.0 million of senior secured notes, the net proceeds of which were
approximately $87.7 million. Star Gas Partners and Petro Holdings guaranteed the
notes.
 
  All of the net proceeds of the equity offering, together with the $87.7
million of estimated net proceeds from the debt offering and $5.4 million of
Petro's cash were used:
 
  .  to redeem $79.5 million of Petro's 12 1/4% Senior Subordinated
     Debentures due 2005, $46.1 million of Petro's 10 1/8% Senior
     Subordinated Notes due 2003, $68.3 million of Petro's 9 3/8% Senior
     Subordinated Debentures due 2006 and the $7.4 million of Petro's 12 7/8%
     preferred stock;

 
  .  to repurchase Petro's 1989 preferred stock; and
 
  .  to pay for a portion of the expenses of the transaction.
 
  In lieu of a portion of the cash purchase price that would otherwise be due to
the holders of the Petro 12 7/8% preferred stock, Star Gas Partners may in the
future issue an additional 175,000 senior subordinated units.
 
New General Partner
 
  Since Star Gas Corporation is a wholly-owned subsidiary of Petro and was
acquired as Star Gas Partners' subsidiary in the transaction, it was no longer
able to serve as Star Gas Partners' general partner. Star Gas Partners' new
general partner is Star Gas LLC, which is owned by the LLC Owners. Star Gas
LLC's business activities are limited to those related to being our general
partner. Star Gas LLC does not have a significant net worth except for its
interest in Star Gas Partners.
 
Amendment of Partnership Agreement
 
  In order to complete the transaction, Star Gas Partners needed to amend its
partnership agreement and Star Gas Propane's partnership agreement in effect
before the transaction. The amendment, among other matters, increased the
minimum quarterly distribution from $0.55 to $0.575 per unit. 
 
Outstanding Star Gas Partners Units
 
  The following table sets forth the approximate number of units outstanding
before and after completion of the transaction. The 325,729 general partner
interests/units represent 324,100 general partner units in Star Gas Partners
and the 0.01% general partner interest in Star Gas Propane. This 0.01% is
deemed to be in unit form solely for purposes of this table.

Relationship of the Parties. Star Gas Partners' former general partner, Star Gas Corporation, is a wholly- owned subsidiary of Petro. Petro also owned an aggregate 40.5% equity interest in Star Gas Partners. Moreover, all of the directors of Petro were also directors of Star Gas Corporation. As a result, Petro controlled Star Gas Partners. In order to protect the interests of the Star Gas Partners common unitholders, the Star Gas Corporation board appointed a special committee consisting of the two directors who were not also directors of Petro to negotiate the transaction on behalf of the Star Gas Partners common unitholders. Independent legal counsel represented the special committee in the negotiations. Item 3. Bankruptcy or Receivership None. Item 4. Change in Registrant's Certifying Accountant None. Item 5.

                         UNAUDITED PRO FORMA CONDENSED
                       CONSOLIDATED FINANCIAL INFORMATION
 
  The following unaudited pro forma condensed consolidated financial
information gives effect to the acquisition of Petro by Star Gas Partners, the
transaction, including the equity offering, the debt offering and the
application of the net proceeds from these offerings. The information presented
is derived from, should be read in conjunction with, and is qualified in its
entirety by, reference to the historical financial statements, and related
notes, appearing elsewhere and incorporated by reference in this prospectus.
 
  The unaudited pro forma condensed consolidated balance sheet was prepared as
if the transaction had occurred on December 31, 1998. The unaudited pro forma
condensed consolidated statement of operations for the twelve months ended
September 30, 1998 was prepared as if the transaction had occurred on October
1, 1997. The unaudited pro forma condensed consolidated statement of operations
for the three months ended December 31, 1998 was prepared as if the transaction
had occurred on October 1, 1998.
 
  The pro forma adjustments are based upon currently available information and
certain estimates and assumptions described below, and therefore, the actual
adjustments may differ from the unaudited pro forma adjustments. However,
management believes that the assumptions provide a reasonable basis for
representing the significant effects of the transaction as contemplated and
that the unaudited pro forma adjustments give appropriate effect to those
assumptions and are properly applied in the unaudited pro forma condensed
consolidated financial information. The unaudited pro forma condensed
consolidated balance sheet and statement of operations are not necessarily
indicative of the financial position or results of operations of Star Gas
Partners if the transaction had actually occurred on the dates indicated above.
Likewise, the unaudited pro forma condensed consolidated financial information
is not necessarily indicative of future financial combined position or future
results of combined operations of Star Gas Partners.

Star Gas Partners, L.P. and Subsidiaries Notes to Pro Forma Condensed Consolidated Financial Information The following pro forma adjustments give effect to: (1) the offering of 809,000 common units by Star Gas Partners on December 16, 1997; (2) the acquisition of Petro; (3) the debt offering; and (4) this offering, as if each transaction had taken place on December 31, 1998, in the case of the pro forma condensed consolidated balance sheet, or as of October 1, 1997, in the case of the pro forma condensed consolidated statement of operations for the twelve months ended September 30, 1998, or as of October 1, 1998, in the case of the pro forma condensed consolidated statement of operations for the three months ended December 31, 1998. The pro forma adjustments are based upon currently available information, estimates and assumptions and a preliminary determination and allocation of the total purchase price for Petro and therefore the actual results may differ from the pro forma results. However, management believes that the assumptions provide a reasonable basis for presenting the significant effects of the transactions as contemplated, and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the pro forma financial information. Transaction Related Adjustments (a) Reflects the accrued dividends payable on Petro's 1989 preferred stock and 12 7/8% preferred stock. (b) Reflects the negotiated discount of approximately $15.8 million to redeem Petro's 12 7/8% preferred stock, the negotiated discount of approximately $9.4 million to refinance Petro's public debt and the negotiated premium to refinance Petro's private debt of approximately $2.9 million. (c) Reflects the issue of 0.8 million shares of junior preferred stock of Petro, which was converted into 0.1 million common units upon completion of the transaction at an assumed value of $14.1875 per unit. The junior preferred stock was issued to the holders of Petro's 9 3/8% subordinated debentures, 10 1/8% subordinated notes, and 12% subordinated debentures, and 12 7/8% preferred stock as consideration for consenting to the early redemption of those securities. The Transaction (Merger and Exchange) (d) Represents: (1) the estimated amount of current federal and state taxes to be incurred of $4.6 million; (2) the estimated amount of deferred federal and state income taxes to be recognized of $40.0 million; and (3) the elimination of the tax liability associated with the Pearl Gas conveyance of $3.5 million. (e) Reflects the estimated additional amount of $3.7 million to be recorded by Petro for legal, professional and advisory fees incurred by Petro and Star Gas Partners in the transaction. Total estimated expenses are $8.5 million. As of September 30, 1998 Petro has recorded $1.1 million in transaction expenses. For the three months December 31, 1998, Petro has recorded $3.8 million in transaction expenses. (f) Represents the exchange of 26.2 million shares of Petro's Class A common stock and Class C common stock valued at $49.9 million for 2.5 million Star Gas Partners senior subordinated units valued at $40.2 million, 0.4 million Star Gas Partners junior subordinated units valued at $5.3 million and 0.3 million general partner units valued at $4.4 million. The 2.4 million Star Gas Partners subordinated units outstanding prior to the transaction will be contributed to Star Gas Partners by Petro. The value assigned to Petro's Class A common stock is $45.0 million or $1.91 per share and the value assigned to Petro's Class C common stock is $4.9 million or $1.91 per share. The method used to determine the fair market value of Petro's Class A and Class C common stock was based on an implied unit analysis. The method used to determine the fair market value of Star Gas Partners' senior subordinated units, junior subordinated units and general partner units was based on an implied unit analysis. See page 68 of the joint proxy statement and prospectus of Star Gas Partners, L.P. and Petroleum Heat and Power Co., Inc. dated February 10, 1999 for a description of the implied unit analysis method. The table below summarizes the preliminary allocation by Star Gas Partners of the excess of purchase price over book value related to the acquisition of Petro. The allocation of the purchase price is based on the results of a preliminary appraisal of property, plant and equipment, customer lists and the December 31, 1998 recorded values for tangible assets and liabilities. The closing date of the transaction was March 26, 1999. This purchase price allocation will be updated for changes in current assets and liabilities based on Petro's operating results from January 1, 1999 to March 26, 1999. From January 1, 1999 to the closing date, it is expected that Petro will generate net income and positive cash flows and that working capital will increase. As a result, the amount of goodwill to be recorded on the closing date will decrease. Subject to Petro's operating results which could be impacted by weather, among other factors, it is estimated that the increase in working capital for Petro from January 1, 1999 to the closing date will range between $35 million to $40 million. The preliminary allocation is as follows: (In thousands) Consideration given for the exchange of Petro shares........... $ 49,856 Transaction expenses (1)....................................... 8,547 ------------- Total consideration........................................ 58,403 ------------- Fair market value of Petro's assets and liabilities as of December 31, 1998: Current assets...............................................

- -------- (1) Transaction expenses include legal, accounting, investment advisory and asset appraisal costs. (2) Includes fair market value adjustment of $12.0 million. The fair market value for property plant and equipment, excluding real estate, was established using the cost approach method. The market approach was used in valuing the real estate. The value assigned to customer lists was derived using a discounted cash flow analysis. The cash flows attributable to the customer lists were discounted back at an equity risk adjusted cost of capital to the net present value. Any excess was attributable to goodwill. The Debt Offering and The Equity Offering (g) Reflects the net proceeds to Petro of approximately $87.7 million from the $90.0 million debt offering, net of underwriting discounts and commissions estimated to be $1.4 million and offering expenses of approximately $0.9 million. These costs are being amortized over the term of the related debt which is 8.5 years. (h) Reflects the net proceeds to Star Gas Partners of approximately $116.1 million from the issuance and sale of 8.7 million common units in the equity offering at an offering price of $14.1875 per common unit, net of underwriting discounts and commissions of approximately $6.2 million and offering expenses of approximately $1.4 million. The Propane Acquisitions (i) Represents the results of certain propane distributors acquired by Star Gas Partners in fiscal 1998 from October 1, 1997 to their dates of acquisition. Results of these distributors from the dates of acquisition to September 30, 1998 are included in Star Gas Partners' twelve months ended September 30, 1998 results adjusted for: (1) cost savings of $0.3 million, primarily executive compensation and legal expenses relating to selling shareholders; (2) additional depreciation and amortization of $0.5 million; and (3) additional interest expense of $0.4 million. There were no propane acquisitions completed in the three months ended December 31, 1998. The Transaction (Acquisition of Petro) (j) Represents the results of operations of Petro for the twelve months ended September 30, 1998 or the three months ended December 31, 1998. Estimated expenses of $8.5 million to be incurred by Petro as a direct result of its acquisition by Star Gas Partners will be included in Petro's actual statement of operations. For the twelve months ended September 30, 1998, Petro has recorded $1.1 million of these expenses. For the three months ended December 31, 1998, Petro has recorded $3.8 million of these expenses. (k) Adjustment to reflect the disposition of Petro's Hartford, Connecticut operations in November 1997. Petro received cash proceeds of $15.6 million and recorded a gain of $11.3 million. The carrying value of these assets at the time of sale was $4.3 million. (l) Adjustment to depreciation and amortization expense attributable to the acquisition of Petro. Star Gas Partners believes that the amortization periods assigned to the assets below are appropriate. However, if the final amortization periods assigned to the tangible and intangible assets were of shorter duration, the amount of depreciation and amortization would increase and reduce net income. For the twelve months ended September 30, 1998, the following table summarizes the effect on depreciation and amortization of the acquisition of Petro.

- ------- (1) As of December 31, 1998. (2) For the twelve months ended September 30, 1998. Petro's property, plant and equipment is being depreciated using a historical cost which is approximately $80 million. The fair market value of these assets is $40.1 million. When depreciation expense is calculated based on the fair market value, this expense is $2.1 million lower than historical depreciation. Pro forma depreciation is less than historical depreciation due to decline in the asset base being depreciated and an extension of the useful lives of those assets. The remaining lives assigned to property, plant and equipment were determined by an independent appraisal firm. All property, plant and equipment is depreciated using the straight-line method. Pro forma customer list amortization is less than historical amortization due to a longer life and a lower amortization asset. The original cost used to amortize historical customer list was approximately $120 million. The longer life represents Petro's improved retention rate as well as the retention of customers obtained through internal marketing, which have a higher retention rate than for customers acquired through acquisition. Petro's previous acquisitions represented the acquisition of customers. The acquisition of Petro by Star Gas Partners is an acquisition of an on-going business. The appraisal assigned a greater allocation to goodwill than what was previously allocated by Petro in their purchase of a 188 relatively small fuel oil dealers. This resulted in approximately $7.8 million of additional amortization, largely offsetting the $7.9 million of less customer list amortization. Restrictive covenants were not assigned a value under the pro forma intangibles due to the minimal amount of the asset value expected at closing. Intangibles are amortized on a straight-line basis. For the three months ended December 31, 1998, the following table summarizes the effect on depreciation and amortization of the acquisition of Petro.

- ------- (1) As of December 31, 1998. (2) For the three months ended December 31, 1998. (m) Reflects the elimination of Petro's equity interest in Star Gas Partners. The Offerings (n) Reflects the net adjustment for the twelve months ended September 30, 1998 to amortization of debt issuance costs of $1.2 million attributable to the debt offering and the acquisition of Petro. Amortization of debt issuance costs is decreased by $1.4 million relating to the repayment of Petro debt and is increased by $0.3 million relating to the 7.92% notes. For the three months ended December 31, 1998, amortization of debt issuance costs is decreased by $0.3 million relating to the repayment of Petro debt and is increased by $0.1 million relating to the 7.92% notes. (o) Reflects the use of the net proceeds from the equity offering and, the debt offering to repay $79.5 million of Petro's 12 1/4% Senior Subordinated Debentures due 2005 to repay $46.1 million of Petro's 10 1/8% Senior Subordinated Notes due 2003, to repay $68.3 million of Petro's 9 3/8% Senior Subordinated Debentures due 2006, to retire $7.4 million of Petro's 12 7/8% Exchangeable Preferred Stock, to retire $4.2 million of Petro's 14.33% Exchangeable Preferred Stock and to pay $3.7 million of transaction expenses. As of December 31, 1998 Petro had paid $4.9 million in transaction expenses. As a result of the transaction, both Petro's current and long-term restricted cash balances become available for general business purposes. In addition, Petro has entered into private debt agreements with the private noteholders of: (i) its outstanding senior notes in the aggregate principal amount of $60 million; and (ii) its Petro private debt in the aggregate principal amount of $4.1 million (after payment of the January 1999 installment). Under the private debt agreements at the effective time of the transaction: (i) the holders of the senior notes exchanged those notes for $62.7 million aggregate principal amount of new 9% notes; and (ii) the holders of the 14.1% notes exchanged those notes for $4.2 million aggregate principal amount of 10 1/4% notes. The new private notes have been guaranteed by Star Gas Partners and Petro Holdings. (p) Reflects the exchange of $5.4 million of Petro's 12 7/8% exchangeable preferred stock for 0.4 million common units in lieu of cash. (q) Reflects the net reduction to interest expense of $16.3 million for the twelve months ended September 30, 1998. This amount reflects $7.1 million of additional interest expense annually on the $90.0 million in principal amount of the notes at an interest rate of 7.92%. This amount also reflects an annual reduction in interest expense of $21.9 million due to the repayment of $203.2 million of Petro public debt, excluding negotiated discounts, with the proceeds of this offering and the debt offering and a reduction in the interest rate attributable to the private debt agreements described above. In addition interest expense is reduced by $0.3 million, as $5.4 million of Petro's cash is used to finance the transaction. The following table summarizes the effect on interest expense of the transaction for the twelve months ended September 30, 1998:
Interest Interest Amount Rate Expense ------- -------- -------- Debt Repaid or Modified Petro 12 1/4% senior subordinated debentures(1).... $80,155 12.25% $ 9,819 Petro 10 1/8% senior subordinated notes............ 48,739 10.125% 4,934 Petro 9 3/8% senior subordinated debentures........ 74,334 9.375% 6,968 Petro 11.96% notes(2).............................. 60,000 11.96% 7,176 Petro 14.10% notes(2).............................. 6,884 14.10% 971 Lower letter of credit fees on acquisition notes... 191 ------- Total reductions to interest expense............. $30,059 Interest Amount Rate ------- -------- New Debt Issued and Cash Balance Reduction Petro 7.92% notes.................................. $90,000 7.92% $(7,128) Petro 9.0% senior notes(2)......................... 62,697 9.0% (5,643) Petro 10.25% senior and subordinated notes(2)...... 7,064 10.25% (724) Lower invested cash balances....................... 5,369 5.31% (285) ------- Net reduction to interest expense.................. $16,279 =======

- -------- (1) Excludes prepayment premium of $2.8 million. (2) Notes exchanged under the private debt agreement. (r) The partnership agreement provides that for each non-overlapping four quarter period that occurs after the first anniversary of the transaction, but before the fifth anniversary of the transaction, in which the dollar amount of Petro Adjusted Operating Surplus per Petro Unit equals or exceeds $2.90. Star Gas Partners will issue 303,000 senior subordinated units, pro rata, or 303,000 Class B common units, pro rata, if such issuance occurs after the end of the subordination period. These additional senior subordinated units will be issued to the current holders of the senior subordinated units, junior subordinated units and the general partner units. Star Gas Partners may not issue more than an aggregate of 909,000 senior subordinated units or Class B common units under this provision. In addition, Star Gas Partners has agreed to issue to the holders of Petro's 12 7/8% exchangeable preferred stock 175,000 senior subordinated units contingent upon Star Gas Partners earning $2.40 per unit in distributable cash flow over four consecutive quarters during this period commencing on January 1, 2000 and ending on December 31, 2002. The issuance of these senior subordinated units will not generate any additional proceeds to Star Gas Partners. When these units are issued, an additional amount of goodwill will be recorded. Assuming 303,000 senior subordinated units are issued, the amount of goodwill to be recorded will be $4.9 million. As a result, annual amortization expense would increase by $0.2 million and would decrease net income per limited partner unit by $0.01 per unit. If these senior subordinated units are issued and they are converted into Class B common units, the Class A common units would be diluted in terms of available cash to be used for payment of the quarterly distributions.
