To Each of the Purchasers Listed

Ladies and Gentlemen:

     Star Gas Propane, L.P., a Delaware limited partnership (the "Star Gas"),
and Star/Petro, Inc., a Minnesota corporation ("Star/Petro"; Star Gas together
with Star/Petro are each hereinafter referred to as an "Obligor" and
collectively as the "Obligors"), hereby agree with the purchasers named on
Schedule A to this Agreement (the "Purchasers") as follows:

Section 1.  Authorization of Notes.

     The Obligors will authorize the issue and sale of (a) $12,500,000 aggregate
principal amount of their 8.67% First Mortgage Notes, Series A, due March 30,
2012 (the "Series A Notes") and (b) $15,000,000 aggregate principal amount of
their 8.72% First Mortgage Notes, Series B, due March 30, 2015 (the "Series B
Notes"; said Series B Notes together with the Series A Notes are hereinafter
referred to collectively as the "Notes," such term to include any Notes issued
in substitution therefor or replacement thereof pursuant to Section 14).  The
Series A Notes and the Series B Notes shall be substantially in the forms of
Exhibits A1 and A2, respectively, with such changes therefrom, if any, as may be
approved by the Purchasers and the Obligors.  Certain capitalized terms used in
this Agreement are defined in Section 13; references to a "Section" or a
"Schedule" or an "Exhibit" are, unless otherwise specified, to a Section of this
Agreement or to a Schedule or an Exhibit attached to this Agreement.

Section 2.  Sale and Purchase of Notes.

     Subject to the terms and conditions of this Agreement, the Obligors will
issue and sell to the Purchasers and the Purchasers will purchase from the
Obligors, at the Closing provided for in Section 3, Notes in the principal

<PAGE>

Section 3.  Closing.

     The sale of the Notes to the Purchasers shall take place at the offices of

on March 30, 2000, or such later date as may be agreed upon by the Obligors and
the Purchasers.  At the Closing, the Obligors will deliver to each Purchaser
Notes of the series to be purchased by such Purchaser in the principal amount to
be purchased by such Purchaser, in the form of a single Note of such series (or
such greater number of Notes of such series as such Purchaser may request), each

name of such Purchaser's nominee as indicated in Schedule A), against payment of
the purchase price therefor by transfer of immediately available funds to the
Obligors, or as otherwise directed by the Obligors in writing, on the date of
the Closing.  If at the Closing the Obligors shall fail to tender such Notes to
any such Purchaser as provided above in this Section 3 or if any of the
conditions specified in Section 4 shall not have been fulfilled to any such
Purchaser's satisfaction, such Purchaser shall, at its election, be relieved of
all further obligations under this Agreement, without thereby waving any other
rights such Purchaser may have by reason of such failure or such nonfulfillment.

Section 4.  Conditions to Closing.

     Each Purchaser's obligation to purchase and pay for the Notes to be sold to
it at the Closing is subject to the fulfillment to such Purchaser's
satisfaction, prior to or at the Closing, of the following conditions:

and warranties of each of the Obligors and its Affiliates contained in this
Agreement, the other Operative Agreements, and those otherwise made in writing

made and at the time of the Closing, except as affected by the consummation of
such transactions.

          Section 4.2.  Performance; No Default.  Each of the Obligors and
its Affiliates shall have performed and complied with all agreements and
conditions contained in this Agreement or any other Operative Agreement required
to be performed or complied with by it prior to or at the Closing, and at the
time of the Closing no Event of Default or Potential Event of Default under this
Agreement or default by any party under any other Operative Agreement shall have
occurred and be continuing.

          Section 4.3.  Compliance Certificates.  Each of the Obligors shall
have delivered to such Purchaser an Officers' Certificate, dated the date of the
Closing and satisfactory in substance and form to such Purchaser, certifying
that the conditions specified in Sections 4.1 and 4.2 have been fulfilled and
certifying that no material adverse change has occurred in the financial
condition of the Business subsequent to the date of the most recent audited
financial statements delivered pursuant to Section 5.4(b).

Insurance Law) permitting, limited investments by insurance companies in
securities not otherwise legally eligible for investment.  If requested by such
Purchaser by prior written request to the Obligors, such Purchaser shall have
received, at least five Business Days prior to the Closing, an Officers'

all necessary partnership corporate or limited liability company action to
authorize the execution, delivery and performance by it of this Agreement, the
Notes and each other Operative Agreement to which it is a party.  Each of the
Obligors and the General Partner has duly executed and delivered each of this

          Section 5.5.  Changes, Etc.  Except as contemplated by this
Agreement, the other Operative Agreements or the Offering Materials, subsequent

the Bank Credit Facilities, (b) no events have occurred, which individually or
in the aggregate, could have a Material Adverse Effect, and (c) there has not

under the Bank Credit Facilities except for Indebtedness incurred under the Bank
Credit Facilities that was and is permitted by the 1998 Note Agreement, the
1995 Note Agreements and the Bank Credit Facilities.

          Section 5.6.  Tax Returns and Payments.  Each of the Obligors and its
Affiliates has filed all tax returns required by law to be filed by it and has
paid all taxes, assessments and other governmental charges levied upon it or any

by appropriate proceedings diligently conducted for which such reserves or other
appropriate provisions, if any, as shall be required by GAAP have been made.
Star Gas is a limited partnership not subject to taxation with respect to its
income or gross receipts under applicable Federal laws.

          Section 5.7.  Indebtedness.  Other than the Indebtedness represented
by the Notes and the Indebtedness listed in Schedule 5.7, neither of the
Obligors nor the General Partner has any secured or unsecured Indebtedness
outstanding.  No instrument or agreement to which either of the Obligors or,
other than Section 6.6(g) of the MLP Agreement, the General Partner is a party
or by which either of the Obligors or the General Partner is bound or which is
applicable to either of the Obligors or the General Partner (other than this
Agreement, the 1995 Note Agreements, the 1998 Note Agreement and the Bank Credit
Facilities) contains any restrictions on the incurrence by either of the
Obligors or the General Partner of additional Indebtedness.

          Section 5.8.  Transfer of Assets and Business.  (a) Each of the
Obligors is in possession of and operating in compliance in all respects with
all franchises, grants, authorizations, approvals, licenses, permits, easements,
rights-of-way, consents, certificates and orders required to own, lease or use
its properties and to permit the conduct of the Business as now conducted and
proposed to be conducted, except for those franchises, grants, authorizations,
approvals, licenses, permits, easements, rights-of-way, consents, certificates
and orders (collectively, "Permitted Exceptions") (i) which are not required at
this time and are routine or administrative in nature and are expected in the
reasonable judgment of Star/Petro or the General Partner, as the case may be, to

Closing, or (ii) which, if not obtained or given, would not, individually or in
the aggregate, have a Material Adverse Effect.

      (b) Each of the Obligors has (i) good and marketable title to the portion
of the Assets constituting real property owned in fee simple by such Obligor,
(ii) good and valid leasehold interests in the portion of the Assets

personal property for the use and operation of such personal property as it has
been used in the past and as it is proposed to be used in the Business, in each
case subject to no Liens except Permitted Encumbrances.  The Assets are all of
the assets and properties necessary to enable the Obligors to conduct the
Business and include all options to purchase or rights of first refusal granted
to or for the General Partner with respect to any of the Assets leased by the
General Partner.  Each of the Obligors enjoys peaceful and undisturbed
possession under all leases necessary for the operation of its properties and
assets, and all such leases are valid and subsisting and are in full force and
effect.  Except to perfect and to protect security interests of the character
described by Section 10.2, (A) at the time of the Closing, no effective
financing statement under the Uniform Commercial Code which names either of the
Obligors or the General Partner (with respect to any of the Assets) as debtor,
which individually or in the aggregate relates to any part of the Assets, will
be on file in any jurisdiction and (B) at the time of the Closing, neither of
the Obligors nor the General Partner (with respect to the Assets) will have
signed any effective financing statement (other than financing statements in
favor of the Trustee) or any effective security agreement, which relates to any
part of the Assets, authorizing any secured party thereunder to file any such
financing statement, except for financing statements to be executed and filed in
connection with the Closing.

          Section 5.9.  Litigation, Etc.  There is no action, proceeding or
investigation pending or, to the best knowledge of either of the Obligors or the
General Partner upon reasonable inquiry, threatened (or any basis therefor known
to either of the Obligors or the General Partner) which questions the validity
of this Agreement, any other Operative Agreement or the Notes or any action
taken or to be taken pursuant to this Agreement, any other Operative Agreement
or the Notes, or which might have, either in any case or in the aggregate, a
Material Adverse Effect.

          Section 5.10.  Compliance with Other Instruments, Etc.  Neither of
the Obligors nor the General Partner (a) is in violation of, in the case of Star
Gas, any term of the Partnership Agreement or, in the case of Star/Petro, its
certificate of incorporation or by-laws, or, in the case of the General Partner,
its limited liability company agreement, or (b) is in violation of any term of
any other agreement or instrument to which such Obligor or the General Partner
is a party or by which any of them or any of their properties is bound or any
term of any applicable law, ordinance, rule or regulation of any governmental
authority or any term of any applicable order, judgment or decree of any court,
arbitrator or governmental authority, the consequences of which, in the case of
clause (b), would have a Material Adverse Effect; the execution, delivery and
performance by each of the Obligors and the General Partner of this Agreement
and the other Operative Agreements to which it is a party and the Notes will not
result in any violation of or be in conflict with or constitute a default under
any such term or result in the creation of (or impose any obligation on either
of the Obligors or the General Partner to create) any Lien upon any of the
properties or assets of either of the Obligors or the General Partner prohibited
by any such term; and there is no such term the compliance with which would
have, or in the future may in the reasonable judgment of either of the Obligors
or the General Partner be likely to have, a Material Adverse Effect.

          Section 5.11.  Governmental Consent.  No consent, approval or
authorization of, or declaration or filing with, any governmental authority is
required for the valid execution, delivery

                                      -8-

Permitted Exceptions), and no such consent, approval, authorization, declaration
or filing is required for the valid offer, issue, sale and delivery of the Notes

          Section 5.12.  Offer of Notes.  Neither of the Obligors nor any of
their Affiliates nor anyone acting on any of their behalf has directly or
indirectly offered the Notes or any part thereof or any similar securities for
sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, anyone other than the
Purchasers and not more than nine other institutional investors.  Neither of the
Obligors nor the General Partner nor anyone acting on any of their behalf has
taken or will take any action which would subject the issuance and sale of the
Notes to the registration and prospectus delivery provisions of the Securities
Act of 1933, as amended, or to the registration or qualification provisions of
any securities or Blue Sky law of any applicable jurisdiction or require
registration of any Security Document under the Trust Indenture Act of 1939, as
amended.

          Section 5.13.  Use of Proceeds.  The proceeds of the sale of the
Notes will be used to repay Indebtedness incurred under the Bank Credit
Facilities and for general partnership purposes.

          Section 5.14.  Federal Reserve Regulations.  Neither of the
Obligors nor the General Partner will, directly or indirectly, use any of the
proceeds of the sale of the Notes for the purpose, whether immediate, incidental
or ultimate, of buying a "margin stock" or of maintaining, reducing or retiring
any indebtedness originally incurred to purchase a stock that is currently a
"margin stock," or for any other purpose which might constitute this transaction
a "purpose credit," in each case within the meaning of Regulation U of the Board
of Governors of the Federal Reserve System (12 C.F.R. 221, as amended), or
otherwise take or permit to be taken any action which would involve a violation
of such Regulation U or of Regulation X (12 C.F.R. 224, as amended) or any other
applicable regulation of such Board.  No indebtedness being reduced or retired,
directly or indirectly, out of the proceeds of the sale of the Notes was
incurred for the purpose of purchasing or carrying any stock which is currently
a "margin stock," and none of the Obligors, the General Partner or the Public
Partnership owns or has any present intention of acquiring any amount of such
"margin stock."

          Section 5.15.  Investment Company Act.  Neither of the Obligors nor
the General Partner is an "investment company," or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

          Section 5.16.  Public Utility Holding Company Act; Federal Power Act.
Neither of the Obligors nor the General Partner is a "holding company," or a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," as such terms are
defined in the Public Utility Holding Company Act of 1935, as amended; none of
the Obligors, the General Partner or the issue and sale of the Notes is subject
to regulation under such Act; and neither of the Obligors nor the General
Partner is a "public utility" as such term is defined in the Federal Power Act,
as amended.

          Section 5.17.  ERISA.  (a) None of the Obligors, the General Partner
or any Related Person (other than Petro or any of its Non-Related Subsidiaries)
has ever established, maintained,

                                      -9-
<PAGE>

contributed to or been obligated to contribute to, and neither of the Obligors
nor any Related Person of either of the Obligors has any liability or obligation
with respect to, any Plan. Neither of the Obligors nor any Related Person of
either of the Obligors has assumed, either by agreement (including the
Partnership Agreement and the other Operative Agreements), by operation of law
or otherwise, any liability or obligation with respect to any "employee benefit
plan" (as defined in ERISA) or any other compensation or benefit arrangement,
agreement, policy, practice or understanding and neither of the Obligors nor any
Related Person of either of the Obligors has any liability or obligation to
provide any amount or type of compensation or benefit in respect of any employee
or former employee of the Business which relates to periods, services performed
or benefits or amounts accrued prior to the transfer of the Business or the
Assets pursuant to the Operative Agreements and the transactions contemplated
thereby. None of the Obligors, the General Partner nor any Related Person has
incurred any material liability under Title IV of ERISA with respect to any such
Plan and no event or condition exists or has occurred as a result of which such
a liability would reasonably be expected to be incurred. None of the Obligors,
the General Partner nor any Related Person has engaged in any transaction,
including the transactions contemplated hereunder which could subject either of
the Obligors or any Related Person of either of the Obligors to liability
pursuant to section 4069(a) or 4212(c) of ERISA. There has been no reportable
event (within the meaning of section 4043(b) of ERISA) or any other event or
condition with respect to any Plan which presents a risk of the termination of,
or the appointment of a trustee to administer, any such Plan by the PBGC. No
prohibited transaction (within the meaning of section 406(a) of ERISA or
section 4975 of the Code) exists or has occurred with respect to any Plan which
has subjected or could reasonably be expected to subject either of the Obligors
or the General Partner to a material liability under section 502(i) of ERISA or
section 4975 of the Code. No liability to the PBGC (other than liability for
premiums not yet due) has been or is expected to be incurred with regard to any
Plan by either of the Obligors, the General Partner nor any Related Person.
Neither of the Obligors, the General Partner nor any Related Person contributes
or is obligated to contribute or has ever contributed or been obligated to
contribute to any single employer plan that has at least two contributing
sponsors not under common control. Neither of the Obligors is, nor are either of
them expected to become, a "substantial employer" as defined in section
4001(a)(2) of ERISA with respect to any Plan. Neither of the Obligors nor the
General Partner has ever maintained or contributed to any plan or arrangement
which provides post-employment welfare benefits or coverage (other than
continuation coverage provided pursuant to section 4980B of the Code).

      (b) The execution and delivery of this Agreement and the issue and sale of
the Notes will not involve any non-exempt "prohibited transaction" within the
meaning of section 406 of ERISA or section 4975 of the Code.  The
representations by each of the Obligors and the General Partner in the
immediately preceding sentence are made in reliance upon and subject to the
accuracy of each Purchaser's representation in Section 6.2 of this Agreement as
to the source of the funds to be used to pay the purchase price of the Notes to
be purchased by such Purchaser.  With respect to each employee benefit plan
identified to the Obligors in accordance with clause (c) of Section 6.2 of this
Agreement, neither of the Obligors nor the General Partner nor any "affiliated"
(as defined in Section V(c) of the QPAM Exemption) of either of the Obligors or
the General Partner has at this time, and has not exercised at any time within
the one year period preceding the date of the Closing, the authority to appoint
or terminate any Purchaser as manager of any of the

                                      -10-
<PAGE>

assets of any such plan or to negotiate the terms of any management agreement
with such Purchaser on behalf of any such plan.

          Section 5.18.  Environmental Matters.  (a) Except as disclosed in
Schedule 5.18, each of the Obligors and the General Partner is in compliance
with all Environmental Laws applicable to it or to the Business or Assets except
where such noncompliance would not have a Material Adverse Effect.  Each of the
Obligors has timely and properly applied for renewal of all environmental
permits or licenses that have expired or are about to expire and are necessary
for the conduct of the Business as now conducted and as proposed to be
conducted, except where the failure to timely and properly reapply would not
have a Material Adverse Effect.  Schedule 5.18 lists (i) all notices from
Federal, state or local environmental agencies to either of the Obligors or to
the General Partner citing environmental violations that have not been finally
resolved and disposed of, and no such violation, whether or not notice regarding
such violation is listed on Schedule 5.18, if ultimately resolved against either
of the Obligors or the General Partner, as the case may be, would have a
Material Adverse Effect, and (ii) all current reports filed by either of the
Obligors or the General Partner with any Federal, state or local environmental
agency having jurisdiction over the Assets, true and complete copies of which
reports have been made available to the Purchasers and their special counsel and
environmental advisor, if any.  Notwithstanding any such notice, the Obligors
and the General Partner are currently operating in all material respects within
the limits set forth in such environmental permits or licenses and any current
noncompliance with such permits or licenses will not result in any material
liability or penalty to either of the Obligors or the General Partner or in the
revocation, loss or termination of any such environmental permits or licenses,
the revocation, loss or termination of which would have a Material Adverse
Effect.

      (b) Except as disclosed in Schedule 5.18, all facilities located on the
real property included in the Assets which are subject to regulation by RCRA are
and have been operated in compliance with RCRA, except where such noncompliance
would not have a Material Adverse Effect and neither of the Obligors nor the
General Partner has received, or, to the knowledge of either of the Obligors or
the General Partner, been threatened with, a notice of violation of RCRA
regarding such facilities.

      (c) Except as disclosed in Schedule 5.18, no hazardous substance (as
defined in CERCLA) or hazardous waste (as defined in RCRA) is located or present
at any of the real property included in the Assets in violation of any
Environmental Law, which violation will have a Material Adverse Effect, and with
respect to such real property there has not occurred (i) any release or
threatened release of any such hazardous substance, (ii) any discharge or
threatened discharge of any substance into ground, surface, or navigable waters
which violates any Federal, state, local or foreign laws, rules or regulations
concerning water pollution, or (iii) any assertion of any Lien pursuant to
Environmental Laws resulting from any use, spill, discharge or clean-up of any
hazardous or toxic substance or waste, which occurrence will have a Material
Adverse Effect.

      (d) None of the matters disclosed in Schedule 5.18, either individually or
in the aggregate, involves a violation of or a liability under any Environmental
Law the consequences of which will have a Material Adverse Effect.

                                      -11-

      (e) Star Gas has performed all of the investigatory and remedial work
recommended in the Environmental Assessment Report prepared by Fuss & O'Neil,
Inc. dated December 7, 1995 (the "Fuss & O'Neil Report"), covering the
properties owned by or to be transferred to Star Gas.  To the extent that any
such additional investigation recommended by the Fuss & O'Neil Report indicated
that any additional work or remediation was required by applicable laws, Star
Gas has completed such additional work or remediation.

      (f) With respect to the above ground storage tanks located at the
facilities owned by Star Gas at Deshler and Hebron, Ohio, Star Gas has completed
the construction of secondary containment walls or barriers designed to contain
any spills or leaks from such tanks.  The construction of such secondary
containment walls or barriers were performed in accordance with all applicable
laws and current industry standards for such walls or barriers.

          Section 5.19.  Foreign Assets Control Regulations, Etc.  The issue and
sale of the Notes by the Obligors and their use of the proceeds thereof as
contemplated by this Agreement will not violate any of the regulations (other
than those regulations, if any, that are implicated solely as a result of the
actions of the Purchasers) administered by the Office of Foreign Assets Control,
the United States Department of the Treasury.

          Section 5.20.  Disclosure.  Neither this Agreement, the other
Operative Agreements, the Offering Materials, nor any other historical financial
statement, document, certificate or instrument delivered to any Purchaser by or
on behalf of either Obligor, any Restricted Subsidiary or the General Partner in
connection with the transactions contemplated by this Agreement, contains any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements contained therein not misleading.  There is no
fact known to either of the Obligors or the General Partner which has or in the
future would (so far as either of the Obligors or the General Partner can now
foresee) have a Material Adverse Effect which has not been set forth or referred
to in this Agreement or the Offering Materials.

          Section 5.21.  Chief Executive Office.  The chief executive office of
each of the Obligors and the General Partner and the office where each maintains
its records relating to the transactions contemplated by the Operative
Agreements is located at 2187 Atlantic Street, Stamford, CT 06902.

Section 6.  Purchaser's Representations; Source of Funds.

          Section 6.1.  Purchase for Investment.  Each Purchaser represents
that it is purchasing the Notes for its own account or for one or more separate
accounts maintained by such Purchaser or for the account of one or more pension
or trust funds, in each case not with a view to or for sale in connection with
any distribution thereof within the meaning of the Securities Act of 1933, as
amended, or with any present intention of distributing or selling any of the
Notes, provided that the disposition of such Purchaser's property shall at all
times be within its control.  If a Purchaser is purchasing for the account of
one or more pension or trust funds (other than pension or trust funds included
in the general account of an insurance company), such Purchaser represents that
(except to the extent that such Purchaser has otherwise advised Chapman and
Cutler and the Obligors in writing) it has sole investment discretion with
respect to the purchase of the Notes to

                                      -12-
<PAGE>

be purchased by such Purchaser pursuant to this Agreement and the determination
and decision on such Purchaser's behalf to purchase such Notes for such pension
or trust funds is being made by the same individual or group of individuals who
customarily pass on such investments.

          Section 6.2.  Source of Funds.  Each Purchaser represents that at
least one of the following statements is an accurate representation as to the
source of funds to be used by such Purchaser to pay the purchase price of the
Notes purchased by such Purchaser hereunder:

            (a) if such Purchaser is an insurance company, no part of such funds
     constitutes assets allocated to any separate account maintained by such
     Purchaser in which an employee benefit plan (or its related trust) has any
     interest other than a separate account that is maintained solely in
     connection with its fixed contractual obligations under which the amounts
     payable, or credited, to such plan and to any participant or beneficiary of
     such plan (including any annuitant) are not affected in any manner by the
     investment performance of the separate account; or

            (b) if such Purchaser is an insurance company, to the extent that
     any of such funds constitutes assets allocated to any separate account
     maintained by such Purchaser, (i) such separate account is a "pooled
     separate account" within the meaning of Prohibited Transaction Class
     Exemption 90-1, in which case such Purchaser has disclosed to the Obligors
     the names of each employee benefit plan whose assets in such separate
     account exceed 10% of the total assets or are expected to exceed 10% of the
     total assets of such account as of the date of such purchase (and for the
     purposes of this subdivision (b), all employee benefit plans maintained by
     the same employer or employee organization are deemed to be a single plan),
     or (ii) such separate account contains only the assets of a specific
     employee benefit plan, complete and accurate information as to the identity
     of which such Purchaser has delivered to the Obligors in writing; or

            (c) if such Purchaser is a "qualified professional asset manager" or
     "QPAM" (as defined in Part V of Prohibited Transaction Class Exemption 84-
     14, issued March 13, 1984 (the "QPAM Exemption")), all of such funds
     constitute assets of an "investment fund" (as defined in Part V of the QPAM
     Exemption) managed by such Purchaser, no employee benefit plan assets which
     are included in such investment fund, when combined with the assets of all
     other employee benefit plans (i) established or maintained by the same
     employer or an affiliate of such employer or by the same employee
     organization and (ii) managed by such Purchaser, exceed 20% of the total
     client assets managed by such Purchaser, the conditions of Section I(g) of
     the QPAM Exemption are satisfied and such Purchaser has disclosed to the
     Obligors the names of all employee benefit plans whose assets are included
     in such investment fund; or

            (d) if such Purchaser is other than an insurance company, all or a
     portion of such funds consists of funds which do not constitute assets of
     any employee benefit plan (other than a governmental plan exempt from the
     coverage of ERISA) and the remaining portion, if any, of such funds
     consists of funds which may be deemed to constitute assets of one or more
     specific employee benefit plans, complete and accurate information as to
     the identity of each of which such Purchaser has delivered to the Obligors
     in writing; or

                                      -13-

            (e) if such Purchaser is an insurance company, to the extent that
     any of such funds constitutes assets of such Purchaser's general account,
     such Purchaser has disclosed to the Obligors the names of each employee
     benefit plan with respect to which the amount of the reserves and
     liabilities for such Purchaser's general account contracts held by or on
     behalf of such plan (within the meaning of Prohibited Transaction Class
     Exemption 95-60) exceed or are expected to exceed on the date of such
     purchase 10% of the total reserves and liabilities of such Purchaser's
     general account (and for the purposes of this subdivision (e), all employee
     benefit plans maintained by the same employer or employee organization are
     deemed to be a single plan).

As used in this Section 6.2, the terms "employee benefit plan," "governmental
plan" and "separate account" shall have the respective meanings assigned to such
terms in section 3 of ERISA.

<PAGE>

discuss with such representatives the affairs, finances and accounts of such
Obligor, any Restricted Subsidiary, such other Subsidiaries, the general partner
of Star Gas or any of such general partner's Subsidiaries, as the case may be),

Event of Default has occurred and is continuing.

Section 9.  Prepayment of Notes.

of the Series B Notes (or such lesser principal amount of the Series B Notes as
shall at the time be outstanding), at the principal amount of the Series B Notes
so prepaid, without premium, together with interest accrued thereon.  No
acquisition of the Series B Notes by either Obligor or any of their Affiliates
shall relieve the Obligors from their obligation to make the required
prepayments provided for in this Section 9.1(b).

     (c) Any partial prepayment of the Notes pursuant to Section 9.2, 9.3 or 9.4
shall be applied pro rata to the Series A Notes and the Series B Notes then
outstanding to reduce (i) in the case of the Series A Notes, the outstanding
principal amount of the Series A Notes and (ii) in the case of the Series B
Notes, the prepayments required under Section 9.1(b) pro rata; provided that, in
the case of the Series B Notes, any amounts prepaid pursuant to Section 9.3 on
March 30, 2011 or any March 30 thereafter to and including March 30, 2014, may
be applied first to satisfy the prepayment required on such date under
Section 9.1(b).

      (d) On the maturity date of each series of Notes, the Obligors will pay
the then outstanding principal amount of such series of Notes together with
interest accrued thereon.

      Section 9.2.  Optional Prepayments of the Notes with Make Whole Amount.
The Notes shall be subject to prepayment, in whole at any time or from time to
time in part (in an amount of not less than $1,000,000), at the option of the
Obligors, upon notice as provided in Section 9.5 at 100% of the principal amount
of the Notes so prepaid plus interest thereon to the prepayment date and the
Make Whole Amount.

      Section 9.3.  Contingent Prepayments on Disposition of Property.  If at
any time either Obligor or any of the Restricted Subsidiaries disposes
of property or such property shall be damaged, destroyed or taken in eminent
domain or there shall be title insurance proceeds with respect to such property,
in any such case, with the result that there are Excess Proceeds, and the
Obligors do not apply such Excess Proceeds in the manner described in
Section 10.7(c)(iii)(B)(x), the Obligors shall prepay, upon notice as provided
in Section 9.5 (which notice shall be given not later than 180 days after the
date of such sale of property), a principal amount of the outstanding Notes
equal to the amount of such Excess Proceeds allocable to the Notes, determined
by allocating such Excess Proceeds pro rata among the holders of the Notes, the
1998 Notes, the 1995 Notes and Parity Debt, if any, outstanding on the date such

                                      -20-

prepayment is to be made, according to the aggregate then unpaid principal
amounts of the Notes (and the Make Whole Amount, if any, on the principal amount
of the Notes to be prepaid), the 1998 Notes, the 1995 Notes and Parity Debt,
respectively; provided, that if such Excess Proceeds are received within 180
days of a scheduled prepayment of the Series B Notes pursuant to Section 9.1(b),
the Excess Proceeds allocable to the Series B Notes may first be applied to such
scheduled prepayment. If the Obligors shall have elected to apply any portion of
the Excess Proceeds in accordance with the proviso to the immediately preceding
sentence, the Obligors shall notify the holders of the Series B Notes of such
application within 5 days thereof. Each prepayment of Notes pursuant to this
Section 9.3 shall be made at 100% of the principal amount of the Notes to be
prepaid, plus interest thereon to the prepayment date plus, to the extent the
prepayment is not made in satisfaction of a required prepayment in accordance
with Section 9.1(b), the Make Whole Amount thereon.

     Section 9.4.  Prepayment on Taking or Destruction.  In the event that
damage, destruction or a taking shall occur in respect of all or a portion of
the properties subject to any of the Security Documents, or there shall be
proceeds under title insurance policies with respect to any real property, all
Net Insurance Proceeds (as defined in the Mortgages), self-insurance amounts,
Net Awards (as defined in the Mortgages) or title insurance proceeds which, as
of any date, shall not theretofore have been applied to the cost of Restoration
(as defined in the Mortgages) shall be deemed to be proceeds of property
disposed of voluntarily, shall be subject to the provisions of Section 10.7(c)
and, if subdivision (iii)(B)(y) of Section 10.7(c) is applicable thereto, shall
be subject to the prepayment provisions of Section 9.3.

     Section 9.5.  Notice of Prepayments; Officers Certificate.  The Obligors
will give each holder of any Notes irrevocable written notice of each prepayment
under Section 9.2, 9.3 or 9.4 not less than 10 days and not more than 30 days
prior to the date fixed for such prepayment, in each case specifying such
prepayment date, the aggregate principal amount of the Notes and the principal
amount of each Note held by such holder to be prepaid and the Section under
which such prepayment is to be made. Notice of prepayment having been given as
aforesaid, the principal amount of the Notes specified in such notice, together
with interest thereon to the prepayment date and together with the Make Whole
Amount, if any, with respect thereto, shall become due and payable on such
prepayment date. The Obligors shall, on or before the day on which they provide
such written notice, give telephonic notice of the principal amount of the Notes
to be prepaid and the prepayment date to each holder of any Notes which shall
have designated a recipient of such notices in the Schedule of Purchasers
attached hereto or by notice in writing to the Obligors. Each holder of a Note
shall receive, on the Business Day immediately preceding the date scheduled for
any such prepayment, an Officers' Certificate from each of the Obligors
certifying that the conditions of the Section under which such prepayment is to
be made have been fulfilled and specifying the particulars of such fulfillment.
In the event that there shall have been a partial prepayment of the Notes under
Section 9.2, 9.3 or 9.4, the Obligors shall promptly give notice to the holders
of the Notes, accompanied by an Officers' Certificate from each of the Obligors
setting forth the principal amount of each of the Notes that was prepaid and
specifying how each such amount was determined and, in the case of the Series B
Notes, setting forth the reduced amount of each required prepayment thereafter
becoming due under Section 9.1(b), and certifying that such reduction has been
computed in accordance with Section 9.1(c).

          Section 9.6.  Allocation of Partial Prepayments.  Upon any partial
prepayment of the Notes, the principal amount so prepaid shall be allocated (in
integral multiples of $1,000 as nearly as practicable) to all Notes at the time
outstanding in proportion to the respective outstanding principal amounts
thereof not theretofore called for prepayment, with adjustments, to the extent
practicable, to compensate for any prior prepayments not made exactly in such
proportion.

          Section 9.7.  Maturity; Surrender, Etc.  In the case of each
prepayment, the principal amount of each Note to be prepaid shall mature and
become due and payable on the date fixed for such prepayment, together with
interest on such principal amount accrued to such date and the applicable Make
Whole Amount, if any.  From and after such date, unless the Obligors shall fail
to pay such principal amount when so due and payable, together with the interest
and Make Whole Amount, if any, as aforesaid, interest on such principal amount
shall cease to accrue.  Any Note paid or prepaid in full shall, after such
payment or prepayment in full, be surrendered to the Obligors and cancelled and
shall not be reissued, and no Note shall be issued in lieu of any prepaid
principal amount of any Note.

          Section 9.8.  Acquisition of Notes.  Neither of the Obligors nor
the general partner of Star Gas shall, nor shall either of the Obligors or the
general partner of Star Gas permit any of their respective Subsidiaries or
Affiliates to, prepay or otherwise retire in whole or in part prior to their
stated final maturity (other than by prepayment pursuant to Section 9.1, 9.2,
9.3 or 9.4 or upon acceleration of such final maturity pursuant to Section 11),

holder or any 1998 Notes, 1995 Notes or Parity Debt (other than pursuant to
scheduled prepayments in accordance with the terms of such Notes, 1998 Notes,
1995 Notes or Parity Debt or any other prepayment of indebtedness outstanding
under the Bank Credit Facilities or any other Parity Debt of a similar revolving
nature).  Any Notes prepaid or otherwise retired or purchased or otherwise
acquired by either of the Obligors, the general partner of Star Gas or any of
their respective Subsidiaries or Affiliates shall not be deemed to be
outstanding for any purpose under this Agreement.

                  (iv) in the case of any sale, lease or other disposition of
          Mortgaged Property which includes real property (or any interest
          therein), or any sale, lease or other disposition of Mortgaged
          Property resulting in the aggregate net proceeds of all such sales,
          leases or other dispositions exceeding $10,000,000, the Trustee shall
          have received an Officers' Certificate from the general partner of
          Star Gas certifying that such sale, lease or other disposition is in
          the best interest of Star Gas and will not have a Material Adverse
          Effect.

     Notwithstanding the foregoing, Star Gas and any Restricted Subsidiary may
sell or dispose of (i) real property assets sold or disposed of within 12 months
of the acquisition of such assets, and (ii) all other assets sold or disposed of
within 6 months of the acquisition of such assets, in each case constituting a
portion of an acquired business, if (y) such assets are specifically designated
to the holders of any Notes in writing prior to such acquisition as assets to be
disposed of, and (z) the Trustee shall have received an Officers' Certificate
from the general partner of Star Gas certifying that the consideration received
for such property is at least equal to its fair value (as determined in good
faith by the general partner of Star Gas).  Such sales under this paragraph will
not be applied towards the annual or cumulative limitations in subdivision (c)
of this Section 10.7.  The holders of Notes agree to take all actions necessary
to cause dispositions of Mortgaged Property made in compliance with this
Section 10.7 to be made free and clear of the Liens created by the Security
Documents.

          Section 10.8.  Partnership or Corporate Existence, Etc.; Business.
(a) (i) Star Gas will at all times preserve and keep in full force and effect
its partnership existence and (subject to the provisions of subdivision (b) of
this Section 10.8) its status as a partnership not taxable as a corporation for
Federal income tax purposes; (ii) Star/Petro will at all times keep in full
force and effect its corporate existence; (iii) each Obligor will cause each
Restricted Subsidiary to keep in full force and effect its partnership or
corporate existence; and (iv) each Obligor will, and each Obligor will cause
each Restricted Subsidiary to, at all times preserve and keep in full force and
effect all of its material rights and franchises (in each case except as
otherwise specifically permitted in Sections 10.6 and 10.7 and except that the
partnership or corporate existence of any Restricted Subsidiary (other than
Star/Petro), and any right or franchise of Star Gas or any Restricted
Subsidiary, may be terminated if, in the good faith judgment of the general
partner of Star Gas, such termination is in the best interest of Star Gas, is
not disadvantageous to the holders of the Notes in any material respect and
would not have a Material Adverse Effect).

      (b) Star Gas shall not be obligated to preserve its status as a
partnership not taxable as a corporation for Federal income tax purposes if
(i) Star Gas's failure to preserve such status shall be the result of an
amendment to the tax laws enacted by the Congress of the United States and
(ii) after giving effect to the loss of such status the ratio of Consolidated
Cash Flow to Maximum Consolidated Pro Forma Debt Service, determined as of the
date of the loss of such status, would be greater than 1.1 to 1.0, assuming, for
the purposes of the computation of Consolidated Cash Flow, that Consolidated
Cash Flow would be reduced by taxes at the applicable tax rate for Star Gas for
such period had Star Gas been taxable as a corporation.

      (c) Neither Obligor will, nor will either Obligor permit any Restricted
Subsidiary to, engage in any lines of business other than the Business in which
the Obligors and their Restricted Subsidiaries are engaged in on the date of
this Agreement and described in the Public Partnership's SEC Form 10-K for the
fiscal year ended September 30, 1999 and other activities incidental or related
to the Business.

          Section 10.9.  Payment of Taxes and Claims.  Each Obligor will, and
each Obligor will cause each Subsidiary to, pay all taxes, assessments and other
governmental charges or levies imposed upon it or any of its properties or
assets or in respect of any of its franchises, business, income or profits when
the same become due and payable, but in any event before any penalty or interest
accrues thereon, and all claims (including, without limitation, claims for
labor, services, materials and supplies) for sums which have become due and
payable and which by law have or might become a Lien upon any of its properties
or assets, and promptly reimburse the holders of the Notes for any such taxes,
assessments, charges or claims paid by them; provided that no such tax,
assessment, charge or claim need be paid or reimbursed if being contested in
good faith by appropriate proceedings promptly initiated and diligently
conducted and if such reserves or other appropriate provision, if any, as shall
be required by GAAP shall have been made therefor and be adequate in the good
faith judgment of the general partner of Star Gas.

          Section 10.10.  Compliance with ERISA.  Neither Obligor will, nor
will either Obligor permit any Subsidiary or Related Person of either Obligor
to:

            (a) (i) engage in any transaction in connection with which either
     Obligor or any Subsidiary could be subject to either a civil penalty
     assessed pursuant to section 502(i) of ERISA or a tax imposed by section
     4975 of the Code, (ii) terminate (within the meaning of Title IV of ERISA)
     or withdraw from any Plan in a manner, or take, or fail to take, any other
     action with respect to any Plan (including, without limitation, a
     substantial cessation of operations within the meaning of section 4062(e)
     of ERISA), (iii) establish, maintain, contribute to or become obligated to
     contribute to any welfare benefit plan (as defined in section 3(1) of
     ERISA) or other welfare benefit arrangement which provides post-employment
     benefits, which cannot be unilaterally terminated by either Obligor,
     (iv) fail to make full payment when due of all amounts which, under the
     provisions of any Plan or applicable law, either Obligor or any Subsidiary
     or Related Person of either Obligor is required to pay as contributions
     thereto, result in the imposition of a Lien or permit to exist any material
     accumulated funding deficiency, whether or not waived, with respect to any
     Plan or (v) engage in any transaction in connection with which either
     Obligor, any Subsidiary or any Related Person of either Obligor could be
     subject to liability pursuant to section 4069(a) or 4212(c) of ERISA, if,
     as a result of any such event, condition or transaction described in
     clauses (i) through (v) above, either individually or together with any
     other such event or condition, could result in (x) the imposition of a Lien
     on any assets or property of either Obligor or (y) any liability to either
     Obligor, any Subsidiary or any Related Person of either Obligor, which
     liability could have a Material Adverse Effect; or

            (b) as of any date of determination (i) permit the amount of
     unfunded benefit liabilities under any Plan maintained at such time by
     either Obligor or any Subsidiary or Related Persons of either Obligor to
     exceed the current value of the assets of any such Plan or (ii) permit the
     aggregate liability incurred by either Obligor and any Subsidiary and
     Related Persons of either Obligor pursuant to Title IV of ERISA with
     respect to one or more terminations of, or one or more complete or partial
     withdrawals from, any Plan to exceed $1,000,000.

As used in this Section 10.10, the term "accumulated funding deficiency" has the
meaning specified in section 302 of ERISA and section 412 of the Code, the term
"current value" has the meaning specified in section 3 of ERISA and the terms
"benefit liabilities" and "amount of unfunded benefit liabilities" have the
meanings specified in section 4001 of ERISA.

          Section 10.11.  Maintenance of Properties; Insurance.  To the
extent required by the Security Documents, each Obligor will maintain or cause
to be maintained in working order and condition, in accordance with normal
industry standards, all properties used or useful in the business of either
Obligor and the Restricted Subsidiaries and from time to time will make or cause
to be made all appropriate repairs, renewals and replacements thereof.  To the
extent required by the Security Documents, each Obligor will maintain or cause
to be maintained, with Permitted Insurers, insurance with respect to its
properties and business and the properties and business of the Restricted
Subsidiaries of the types and in the amounts specified in the Security Documents
and the Trustee shall be named as an additional insured party on each insurance
policy obtained or maintained pursuant thereto.

Obligor will, and each Obligor will cause each Restricted Subsidiary to, perform
and comply with all of its obligations under each of the Operative Agreements to
which it is a party, will enforce each such Operative Agreement against each
other party thereto and will not accept the termination of any such Operative
Agreement, unless the taking of or omitting to take any such action would not
have a Material Adverse Effect, and will not amend, modify or supplement any
Operative Agreement without the prior written consent of the Required Holders,
provided that (a) the MLP Agreement and the Partnership Agreement may be
amended, modified or supplemented without the prior written consent of the
Required Holders if such amendment, modification or supplement would not have a
Material Adverse Effect and Star Gas shall have delivered to each holder of a
Note a copy of such proposed amendment, modification or supplement together with
an Officers' Certificate describing such proposed amendment, modification or
supplement and confirming that such proposed amendment, modification or
supplement would not have a Material Adverse Effect and (b) the Bank Credit
Facilities may be amended, modified or supplemented without the prior written
consent of the Required Holders if such amendment, modification or supplement
may be made without the written consent of any holders of the Notes under the
Trust Agreement.

          Section 10.13.  Chief Executive Office.  Neither Obligor will move
its chief executive office and the office at which it maintains its records
relating to the transactions contemplated by this Agreement and the Security
Documents unless (a) not less than 45 days' prior written notice of its
intention to do so, clearly describing the new location, shall have been given
to the Trustee and each holder of a Note and (b) such action, reasonably
satisfactory to the Trustee and each holder of a Note, to maintain any security
interest in the property subject to the Security Documents at all times fully
perfected and in full force and effect shall have been taken.

          Section 10.14.  Recordation.  The Obligors will promptly, but in

charges then due in connection with the execution, delivery, recording,
publishing, registration and filing of such documents or instruments in such
places.

          Section 10.15.  Information Required by Rule 144A.  Each Obligor
covenants that it will, upon the prior written request of the holder of any
Note, provide such holder, and any qualified institutional buyer designated by
such holder, such financial and other information as such holder may reasonably
determine to be necessary in order to permit compliance with the information
requirements of Rule 144A under the Securities Act of 1933, as amended, in
connection with the resale of Notes, except at such times as such Obligor is
subject to the reporting requirements of section 13 or 15(d) of the Securities
Exchange Act of 1934, as amended.  For the purpose of this Section 10.15, the
term "qualified institutional buyer" shall have the meaning specified in
Rule 144A under the Securities Act of 1933, as amended.

          Section 10.16.  Covenant to Secure Notes Equally.  Each Obligor
covenants that, if it or any Restricted Subsidiary shall create or assume any
Lien upon any of its property or assets, whether

<PAGE>

now owned or hereafter acquired, other than Liens permitted by the provisions of
Section 10.2 (unless prior written consent to the creation or assumption thereof
shall have been obtained pursuant to Section 18), it will make or cause to be
made effective provision whereby the Notes will be secured by such Lien equally
and ratably with any and all other Indebtedness thereby secured so long as any
such other Indebtedness shall be so secured, it being understood that the
provision of such equal and ratable security shall not constitute a cure or
waiver of any related Event of Default.

          Section 10.17.  Compliance with Laws.  Each Obligor will, and each
Obligor will cause each Subsidiary to, comply with all applicable statutes,
rules, regulations, and orders of, and all applicable restrictions imposed by,
the United States, foreign countries, states, provinces and municipalities, and
of or by any governmental department, commission, board, regulatory authority,
bureau, agency and instrumentality of the foregoing, and of or by any court,
arbitrator or grand jury, in respect of the conduct of their respective
businesses and the ownership of their respective properties or business
(including, without limitation, Environmental Laws), except such as are being
contested in good faith by appropriate proceedings promptly initiated and
diligently conducted and if such reserve or other appropriate provision, if any,
as shall be required by GAAP shall have been made therefor or the failure to so
comply would not be expected to have a Material Adverse Effect.

          Section 10.18.  Further Assurances.  At any time and from to time
promptly, the Obligors shall, at their expense, execute and deliver to each
holder of a Note and to the Trustee such further instruments and documents, and
take such further action, as the holders of the Notes may from time to time

     (A) if such designation (and all other prior designations of Restricted
     Subsidiaries or newly acquired or formed Subsidiaries as Unrestricted
     Subsidiaries during the current fiscal year) were deemed to constitute a
     sale by Star Gas of all the assets of the Subsidiary so designated, such

     designated, such Investment would be in compliance with Section 10.3(c), in
     each case with the net proceeds of such sale or the amount of such
     Investment being deemed to equal the net book value of such assets in the
     case of a Restricted Subsidiary or the cost of acquisition or formation in
     the case of a newly acquired or formed Subsidiary, provided, that this
     subdivision (iii) of this Section 10.19(a) shall not apply to an
     acquisition or formation by Star Gas or a Restricted Subsidiary of a newly
     acquired or formed Unrestricted Subsidiary to the extent such acquisition
     or formation (1) is funded solely by the net cash proceeds received by Star
     Gas from the general partner of Star Gas or from the Public Partnership as

            (vii)  On the date of the Closing, Star/Petro shall be designated as

Subsidiary's obligations under the Subsidiary Guarantee Agreement with all or
substantially all of the assets of such Restricted Subsidiary.

          Section 10.20.  Rating.  If (i) the General Partner of Star Gas
shall withdraw as general partner of Star Gas or (ii) if any person (as such
term is used in rule 13(d) or rule 14(d)(2) of the Exchange Act of 1934, as
amended (the "Exchange Act"), as in effect on the date of the Closing), or
related persons constituting a group (as such term is used in rule 13d-5 under

year.

          Section 10.22.  Certain Real Property.  Without affecting the
obligations of either Obligor or any of the Restricted Subsidiaries under any of
the Security Documents, in the event that either Obligor or any Restricted
Subsidiary, at any time after the date of this Agreement, whether directly or
indirectly, acquires any interest in any real property, including any fee or
other ownership interest in one or more properties with an aggregate cost in
excess of $50,000, or any interest under one or more leases of real property for
a term in excess of three years and involving aggregate average payments in
excess of $100,000 per annum (each such interest, an "After Acquired Property"),
the Obligors will, or the Obligors will cause such Restricted Subsidiary to, as
soon as practical provide written notice thereof to each holder of a Note,
setting forth with specificity a description of such After Acquired Property,
the location of such After Acquired Property, any structures or improvements
thereon and an appraisal or its good-faith estimate of the current value of such
real property ("Current Value").  The Required Holders may require the
applicable Obligor or the applicable Restricted Subsidiary to grant and record a
mortgage in favor of the Trustee on such After Acquired Property, provided that
no new mortgage on such After Acquired Property shall be required if the costs
that would be incurred as a result thereof are excessive in relation to the
benefits that would be conferred thereby.  In the event a mortgage is granted,
the applicable Obligor or the applicable Restricted Subsidiary shall execute and
deliver to the Trustee a mortgage, together with such documents or instruments
as the Required Holders shall require.  In no event shall any title insurance
policy for any such After Acquired Property be in an amount which is less than

                                      -41-
<PAGE>

time, the aggregate cost to the Obligors and the Restricted Subsidiaries of each
interest in real property (a) acquired by either Obligor or any Restricted
Subsidiary, whether directly or indirectly, at any time after the date of this
Agreement, at a cost equal to or less than $50,000, (b) at such time, owned
directly or indirectly by either Obligor or any Restricted Subsidiary and
(c) for which a mortgage in favor of the Trustee is not in effect (the
"Aggregate Cost of Unmortgaged Property"), exceeds $500,000, the Obligors will,
as soon as practical, and in any event within 10 Business Days, provide written
notice thereof to each holder of a Note, setting forth with specificity a
description of each such interest in real property, the location of such real
property and an appraisal or its good-faith estimate of the current value of
each such real property. The Required Holders may require the applicable Obligor
or the applicable Restricted Subsidiary to grant and record a mortgage in favor
of the Trustee on one or more of such real property so that the Aggregate Cost
of Unmortgaged Property does not exceed $500,000, provided that no new mortgage
on any such real property shall be required if the costs that would be incurred
as a result thereof are excessive in relation to the benefits that would be
conferred thereby. In the event a mortgage is required, the applicable Obligor
or the applicable Restricted Subsidiary shall execute and deliver to the Trustee
a mortgage, together with such documents or instruments as the Required Holders
shall require. Further, with regard to any interest in real property, including
any fee or other ownership interest in real property or any material lease of
real property, currently owned or held by either Obligor or any Restricted
Subsidiary and which is not being encumbered by a mortgage of even date herewith
(each such interest, an "Existing Unmortgaged Property"), upon the written
request of the Required Holders, the applicable Obligor will, or the Obligors
will cause any applicable Restricted Subsidiary to, execute and deliver to the
Trustee a mortgage, together with such documents or instruments as the Required
Holders shall require. In no event shall the title insurance policy for any such
Existing Unmortgaged Property be in an amount which is less than the Current
Value of such Existing Unmortgaged Property. The Obligors shall pay all fees and
expenses, including reasonable attorneys' fees and expenses and expenses of any
customary environmental due diligence, and title insurance charges and premiums,
in connection with the obligations of the Obligors and the Restricted
Subsidiaries under this Section 10.22.

          Section 10.23.  Sale and Lease-Back Transactions.  Neither Obligor
will, nor will either Obligor cause or permit any of the Restricted Subsidiaries
to, enter into any arrangement, directly or indirectly, with any Person whereby
it shall sell or transfer any property, real or personal, used or useful in its
business, whether now owned or hereafter acquired, and thereafter rent or lease
such property or other property which it intends to use for substantially the
same purpose or purposes as the property being sold or transferred.

          Section 10.24.  Acquisitions.  Except as otherwise permitted by
Section 10.7, neither Obligor will, nor will either Obligor cause or permit any
of the Restricted Subsidiaries to, purchase, lease or otherwise acquire (in one
transaction or a series of transactions) all or any substantial part of the
assets of any other Person, except that (a) either Obligor or any Restricted
Subsidiary may purchase inventory in the ordinary course of business and
(b) either Obligor or any Restricted Subsidiary may engage in any such
acquisition if no Event of Default or Potential Event of Default has occurred
and is continuing at the time of any such acquisition or would occur immediately
after giving effect thereto.

          Section 10.25.  Impairment of Security Interests.  Neither Obligor
will, nor will either Obligor permit any of the Subsidiaries to, take or omit to
take any action, which action or omission might or would have the result of
materially impairing the security interests in favor of the Trustee with respect
to the Mortgaged Property, and neither Obligor will, nor will either Obligor
permit any of the Subsidiaries to, grant to any Person (other than the Trustee)
any interest whatsoever in the Mortgaged Property.

          Section 10.26.  Limitation on Restrictions on Subsidiary Dividends,
Etc.  Neither Obligor will, nor will either Obligor cause or permit any of
the Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any a encumbrance or
restriction on the ability of any Restricted Subsidiary to (a) pay dividends or
make any other distributions on or in respect of its capital stock, or pay any
indebtedness owed to Star Gas or any Restricted Subsidiary, (b) make loans or
advances to Star Gas or any Restricted Subsidiary or (c) transfer any of its
properties or assets to Star Gas or any Restricted Subsidiary, except for such
encumbrances or restrictions existing under or by reason of (i) customary non-
assignment provisions in any lease governing a leasehold interest or other
contract entered into in the ordinary course of business consistent with past
practices or (ii) this Agreement or any other Operative Agreement.

          Section 10.27.  No Other Negative Pledges.  Neither Obligor will,
nor will either Obligor cause or permit any of the Restricted Subsidiaries to,
directly or indirectly, enter into any agreement prohibiting the creation or
assumption of any Lien upon the properties or assets of either Obligor or any
Restricted Subsidiary, whether now owned or hereafter acquired, or requiring an
obligation to be secured if some other obligation is secured, except for this
Agreement, the 1998 Note Agreement, the 1995 Note Agreements, the Bank Credit
Facilities and any Parity Debt Agreement (as defined in the Trust Agreement).

          Section 10.28.  Sales of Receivables.  Neither Obligor will, nor
will either Obligor cause or permit any of the Restricted Subsidiaries to, sell
with recourse, discount or otherwise sell or dispose of its notes or accounts
receivable, except for accounts receivable consisting of assets of an operating
unit sold as a going concern in accordance with all other provisions of this

          Section 10.29.  Fixed Price Supply Contracts; Certain Policies.
(a) Neither Obligor will, nor will either Obligor permit any of the Restricted
Subsidiaries to, at any time be a party or subject to any contract for the
purchase or supply by such parties of propane or other product except where
(i) the purchase price is set with reference to a spot index or indices
substantially contemporaneously with the delivery of such product or
(ii) delivery of such propane or other product is to be made no more than one
year after the purchase price is agreed to.

      (b) Star Gas will not amend, modify or waive the trading policy or supply
inventory position policy existing as of the date of the Closing except that
Star Gas may amend its supply inventory position policy such that such policy
provides that neither it nor any of the Restricted Subsidiaries will hold on

agreement or any such change in such policy.  Subject to the foregoing

          Section 10.30.  Certain Operations.  Neither Obligor shall permit
Petro or any of its Affiliates (other than the Star Gas and the Restricted
Subsidiaries) to acquire a business which derives any revenues from the sale of
propane if, after giving effect to such acquisition, Petro's Pro Forma Propane
Volumes would equal or exceed the lesser of (a) 15% of Star Gas's reported
propane volumes sold for the most recently completed four fiscal quarters which
ended at least 90 days prior to the date of such acquisition and (b) 15 million
gallons of propane (such lesser amount, the "maximum permitted amount").  If as
a result of an acquisition, Petro's Pro Forma Propane Volumes exceed the maximum
permitted amount, Petro shall not be in violation of this Section 10.30 if
within the period of 90 days following such acquisition it completes the
disposition of sufficient propane volume to reduce Petro's Pro Forma Propane
Volumes below the maximum permitted amount.  For purposes of this Section 10.30,
"Petro's Pro Forma Propane Volumes" shall mean the actual propane volumes sold
by Petro and any of its Affiliates (other than Star Gas and the Restricted
Subsidiaries) for the most recently completed four fiscal quarters which ended
at least 90 days prior to the date of determination plus the propane volumes
sold of the propane business to be acquired for the most recently completed four
fiscal quarters which ended at least 90 days prior to the date of determination.
In addition, in the event Petro or any of its Affiliates (other than Star Gas
and the Restricted Subsidiaries) owns a propane business, Star Gas shall not
permit Petro or any such Affiliate to accept as a customer (except for de
minimis, unintentional and isolated acceptances) any Person who is (or was
during the last billing cycle of Star Gas and the Restricted Subsidiaries) a
customer of Star Gas and the Restricted Subsidiaries.

          Section 10.31.  Independent Organizational Existence.  Except as

shall cause each of the Subsidiaries (other than Petro and its Subsidiaries) to
maintain, books, records and accounts that are separate from the books, records
and accounts of Petro or any of its Subsidiaries such that:  (i) the revenues of
Star Gas and its Subsidiaries will be credited to the accounts of Star Gas and
its Subsidiaries only; (ii) all expenses incurred by Star Gas and its
Subsidiaries shall be paid only from the accounts of Star Gas and its
Subsidiaries (other than those paid by Petro and allocated to Star Gas in the
manner set forth in clause (c) of this Section); (iii) only officers and
employees of the general partner of Star Gas, Star Gas and its Subsidiaries in
their capacity as such shall have the authority to make disbursements with
respect to the accounts of Star Gas and its Subsidiaries; (iv) there shall occur
no sharing of accounts or funds between Star Gas and its Subsidiaries (other
than Petro and its Subsidiaries), on the one hand, and Petro or any of its
Subsidiaries, on the other hand, and (v) all cash and funds of Star Gas and its
Subsidiaries (other than Petro and its Subsidiaries) shall be managed separately
from the cash and funds of Petro or any of its Subsidiaries, and there shall not
occur any commingling including for investment purposes, of funds or assets of
Star Gas and its Subsidiaries (other than Petro and its Subsidiaries) with the
funds or assets of Petro or any of its Subsidiaries.

      (b) All full-time employees, consultants and agents of Star Gas and its
Subsidiaries (other than Petro and its Subsidiaries) shall be compensated
directly from the bank accounts of the general partner of Star Gas, Star Gas and
such Subsidiaries for services provided by such employees, consultants and
agents and, to the extent any employee, consultant or agent is also an

                                      -44-
<PAGE>

employee, consultant or agent of Petro or any of its Subsidiaries, the
compensation of such employee, consultant or agent shall be allocated in
accordance with clause (c) of this Section among Star Gas and its Subsidiaries
(other than Petro and its Subsidiaries), on the one hand, and Petro and any of
its Subsidiaries, on the other hand, on a basis which reasonably reflects the
services rendered to Star Gas and its Subsidiaries (other than Petro and its
Subsidiaries).

      (c) All overhead expenses (including telephone and other utility charges)
for items shared by Star Gas and its Subsidiaries (other than Petro and its
Subsidiaries), on the one hand, and Petro or any of its Subsidiaries, on the
other hand, shall be allocated on the basis of actual use to the extent
practicable and, to the extent such allocation is not practicable, on a basis
reasonably related to actual use.

      (d) Star Gas shall not permit Petro or any of its Subsidiaries to be named
as a loss payee or additional insured on the insurance policy covering the
property of Star Gas or any of its Subsidiaries (other than Petro and its
Subsidiaries), or enter into an agreement with the holder of such policy whereby
in the event of a loss in connection with such property, proceeds are paid to
Petro and its Subsidiaries.

          Section 10.32.  Damage, Destruction, Taking, Etc.  In the event of
any damage, destruction or a taking in respect of all or a portion of the
properties subject to any of the Security Documents or in the event there shall
be proceeds under title insurance policies with respect to any real property,
neither Obligor will apply any Net Insurance Proceeds (as defined in the
Mortgages), self-insurance amounts, Net Awards (as defined in the Mortgages) or
title insurance proceeds, if such proceeds (whether resulting from one or a
series of events or circumstances) exceed $25,000,000 in the aggregate, to the
cost of Restoration (as defined in the Mortgages) or to replacements or other
assets without the prior written consent of the Required Holders.

          Section 10.33.  Trust Agreement.  On or prior to the scheduled
maturity date of the 1995 Notes or, if the Obligors shall have elected to prepay
the 1995 Notes, in whole but not in part, prior to such scheduled maturity date,
on or prior to the date scheduled for such prepayment, the Obligors shall cause
the Trust Agreement to be amended (to the extent not previously done so) (a) to
cause the definitions of "Event of Default" and "Potential Event of Default" to
include Events of Default and Potential Events of Default under this Agreement,
(b) to cause the definition of "Requisite Percentage" not to provide any greater
rights under the Trust Agreement to the Banks or any other Parity Lenders (as
defined in the Trust Agreement) than the rights provided to the holders of the
Notes and (c) in such other manner as may be reasonably requested by the
Required Holders.

deposited or paid under this Agreement, the Notes or any other Operative
Agreement, provided that nothing contained herein shall be deemed to require the
Obligors to indemnify the Indemnified Parties for conditions (other than matters
covered by clause (vi) above) first occurring subsequent to the earlier of
(1) the taking of exclusive possession and control of the Mortgaged Property for
operational purposes pursuant to Section 21.10 of the Mortgages or

                                      -70-
<PAGE>

Section 6.03 of the Obligor Security Agreement, or (2) the foreclosure of the
Lien under any Security Document and the transfer of title to the Trustee.

     In case any action, claim, suit or proceeding is brought against an
Indemnified Party by reason of any such occurrence, the Obligors may, and upon
the request of such Indemnified Party will, at the Obligors' expense resist and
defend such action, suit or proceeding or cause the same to be resisted and
defended by counsel for the insurer of the liability or by counsel designated by
the Obligors and reasonably satisfactory to the Indemnified Party, as the case
may be, provided that any Indemnified Party shall be entitled to participate in
any such action, suit or proceeding with counsel of its own choice but at its
own expense.  In any event, if the Obligors fail to assume the defense within a
reasonable time after any such request, the Indemnified Party may assume such
defense or other indemnification obligations and the fees and expenses of its
attorney will be paid by the Obligors.  The obligations of the Obligors under
this Section 16 shall survive any termination or satisfaction of this Agreement.
Any amounts payable to any Indemnified Party under this Section 16 which are not
paid within 15 days after written demand therefor by any Indemnified Party shall
bear interest at the rate of 10.72% per annum from the date of such demand.  In
the event that the Obligors shall be required to pay any indemnity under this
Section 16, the Obligors shall pay the Indemnified Party an amount which, after
deduction of all taxes required to be paid by such Indemnified Party in respect
of the receipt or accrual thereof (after giving credit for any savings in
respect of any such taxes by reason of deductions, credit or allowances in
respect of the payment of the expense indemnified against, and of any other such
taxes), shall be equal to the amount of such indemnity.

      (c) In connection with the Closing, the General Partner and the Obligors
are requesting that each Purchaser make available for funding an amount equal to
the principal amount specified opposite such Purchaser's name in Schedule A.
If, for any reason, on the date scheduled by the General Partner and the
Obligors as the date for the Closing, (i) the closing conditions are not
satisfied by 11:00 a.m. on such scheduled date, (ii) the General Partner and the
Obligors do not, by 11:00 a.m. on such scheduled date reschedule such Closing
for a subsequent date, and (iii) the Closing in fact does not occur on such
scheduled date, the General Partner and the Obligors will protect, indemnify and
hold each Purchaser harmless from and against any and all losses resulting from
such Purchaser's failure or inability to invest on the scheduled date for the
Closing the purchase price of the Notes to be purchased by such Purchaser, for
the period ending on the next following Business Day at a rate of interest equal
to or greater than the rate of interest on such Purchaser's Notes.

Section 17.  Survival of Representations and Warranties.

     All representations and warranties contained in this Agreement or the other
Operative Agreements, or made in writing by or on behalf of the General Partner,
either Obligor, the general partner of Star Gas or any of their Affiliates in
connection with the transactions contemplated by this Agreement or the other
Operative Agreements, shall survive the execution and delivery of this Agreement
and the other Operative Agreements, any investigation at any time made by any
Purchaser or on any Purchaser's behalf, the purchase of the Notes by the
Purchasers under this Agreement and any disposition or payment of the Notes.
All statements contained in any certificate or other instrument delivered by or
on behalf of either Obligor, the General Partner, any

                                      -71-
<PAGE>

Restricted Subsidiary or the general partner of Star Gas pursuant to this
Agreement and/or the other Operative Agreements or in connection with any
amendment, waiver or modification of this Agreement, any of the other Operative
Agreements or the Notes shall be deemed representations and warranties of the
Obligors under this Agreement.

Section 18.  Amendments and Waivers.

     Any term of this Agreement or of the Notes may be amended and the
observance of any term of this Agreement or of the Notes may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only with the written consent of the Obligors and the Required Holders, provided
that, without the prior written consent of the holders of all the Notes at the
time outstanding, no such amendment or waiver shall (a) change the maturity or
the principal amount of, or change the rate of interest or the time of payment
of interest on, or change the amount or the time of payment of any principal or
Make Whole Amount payable on any prepayment of, any Note, (b) release any Lien
against the Mortgaged Property for the benefit of the holders of the Notes,
(c) reduce the aforesaid percentage of the principal amount of the Notes the
holders of which are required to consent to any such amendment or waiver or
change the rights of the holders with respect thereto, (d) change the percentage
of the principal amount of the Notes the holders of which may declare the Notes
to be due and payable as provided in Section 11 or change the rights of the
holders with respect thereto, (e) decrease the percentage of the principal
amount of the Notes the holders of which may rescind and annul any such
declaration as provided in Section 11 or (f) modify the provisions of
Section 9.8.  Any amendment or waiver effected in accordance with this
Section 18 shall be binding upon each holder of any Note at the time
outstanding, each future holder of any Note and the Obligors.

Section 19.  Notices, Etc.

     Except as otherwise provided in this Agreement, notices and other
communications under this Agreement shall be in writing and shall be delivered
by hand, by express courier service or by registered or certified mail, return
receipt requested, postage prepaid, addressed, (a) if to a Purchaser, at the
address for such Purchaser set forth in Schedule A or at such other address as
such Purchaser shall have furnished to the Obligors in writing, except as
otherwise provided in Section 15.2 with respect to payments on Notes held by
such Purchaser or such Purchaser's nominee, or (b) if to any other holder of any
Note, at such address as such other holder shall have furnished to the Obligors
in writing, or, until such other holder so furnishes to the Obligors an address,
then to and at the address of the last holder of such Note who has furnished an
address to the Obligors, or (c) if to either Obligor, at 2187 Atlantic Street,
Stamford, Connecticut 06902 to the attention of Secretary, Star Gas Propane,
L.P., with a copy to Vice President-Finance, Star Gas LLC, at the address listed
immediately above, or at such other address, or to the attention of such other

Section 20.  Reproduction of Documents.

     This Agreement, each other Operative Agreement and all documents relating
thereto, including, without limitation, (a) consents, waivers and notifications
which may hereafter be executed, (b) documents received by the Purchasers at the
Closing (except the Notes themselves), and (c) financial statements,
certificates and other information previously or hereafter furnished to the
Purchasers or any other holder of any Note, may be reproduced by any such
Purchaser or holder by any photographic, photostatic, microfilm, microcard,
miniature photographic or other similar process and such Purchaser or holder may
destroy any original document so reproduced.  Each of the Obligors and the
General Partner agrees and stipulates that, to the extent permitted by
applicable law, any such reproduction shall be admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original is in existence and whether or not such reproduction was made by such
Purchaser or holder in the regular course of business) and any enlargement,
facsimile or further reproduction of such reproduction shall likewise be
admissible in evidence.

Section 21.  Adjustment of Interest Rate.

      (a) Star Gas agrees to maintain a continuing rating relationship with an
Approved Rating Agency lasting as long as the Notes are outstanding, pursuant to
which the Notes shall be re-rated at least annually.

      (b) After April 30, 2000, if the Notes shall cease to have a rating from
an Approved Rating Agency, the interest rate payable on the Notes shall be
increased by 150 basis points effective 20 Business Days from the date that the
Notes cease to have such rating until the date that the Notes are assigned a new
rating by an Approved Rating Agency.

      (c) In the event that the Notes receive a rating below Investment Grade in
a rating of the Notes conducted by an Approved Rating Agency pursuant to
subdivision (ii)(D) or (iii)(E) of Section 10.7(a) or Section 10.20, the
interest rate payable by the Obligors on the Notes shall be increased by 150
basis points effective from the date of the event giving rise to the requirement
that such rating be obtained until such date an Approved Rating Agency gives the
Notes a rating equivalent to or higher than Investment Grade.

      (d) If and when Petro ceases to be a Wholly-Owned Subsidiary, at the
expense of the Obligors, the Notes shall be promptly, but in any event within 20
days from the date of such occurrence, re-rated by an Approved Rating Agency.
In the event the Notes receive a rating below Investment Grade in a rating of
the Notes conducted by an Approved Rating Agency pursuant to the preceding
sentence, the interest rate payable by the Obligors on the Notes shall be
increased by 150 basis points effective from the date Petro ceases to be a
Wholly-Owned Subsidiary until such date an Approved Rating Agency gives the
Notes a rating equivalent to or higher than Investment Grade.

To the Parties named on
  Schedule I attached hereto

Ladies and Gentlemen:

     We have acted as counsel to Star Gas Propane, L.P., a Delaware limited
partnership ("Star Gas"), Star Gas LLC, a Delaware limited liability company
(the "General Partner"), and Star/Petro, Inc., a Minnesota corporation
("Star/Petro"; and together with Star Gas, the "Obligors") (Star Gas, Star/Petro
and the General Partner being collectively referred to herein as the "Loan
Parties" and each being referred to as a "Loan Party"), in connection with the
negotiation, preparation and consummation of the issuance by the Obligors of
$27,500,000 aggregate principal amount of their First Mortgage Notes comprised
of $12,500,000 aggregate principal amount of the 8.67% First Mortgage Notes,
Series A, due March 30, 2012 and $15,000,000 aggregate principal amount of the
8.72% First Mortgage Notes, Series B, due March 30, 2015 (collectively, the
"Mortgage Notes") (the "Transaction"), pursuant to the Note Agreement dated as
of March 30, 2000 (the "Note Agreement") between the Obligors and the purchasers
named on Schedule A thereto (the "Purchasers").  Terms not defined herein shall
have the meanings assigned to them in the Note Agreement.

     We have examined executed copies of the Operative Agreements, originals or
copies, certified or otherwise identified to our satisfaction, of such other
documents, corporate records, certificates of public officials and other
instruments as we have deemed necessary or advisable for purposes of this
opinion.  We have also relied upon and assumed the truth of the representations
and warranties as to factual matters contained in or made pursuant to the Note
Agreement and the other Operative Agreements and examined and relied upon the
originals, or copies certified or otherwise identified to our satisfaction, of
such records, documents, certificates, including a certificate of an officer of
the General Partner, and other instruments, and have made such other
investigations, as we have deemed necessary or advisable for purposes of this
opinion.

     For purposes of the opinions expressed below, we have assumed (i) the
authenticity of all documents submitted to us as originals, (ii) the conformity
to the originals of all documents submitted as certified or photostatic copies
and the authenticity of the originals, and (iii) the due authorization,
execution and delivery of all documents by all parties and the validity and
binding effect thereof (other than the authorization, execution and delivery of
documents by the Loan Parties and the validity and binding effect thereof upon
such parties).

                                   Exhibit B1
                              (to Note Agreement)

<PAGE>

      Based upon the foregoing, we are of the opinion that:

      1.  Each of Star Gas, Star/Petro and the General Partner (a) is a limited
partnership (in the case of Star Gas), a corporation (in the case of Star/Petro)
or a limited liability company (in the case of the General Partner) duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (b) has all requisite power and authority to
own its property and assets and to carry on its business as now conducted and as
proposed to be conducted and (c) is duly qualified or registered to do business
and is in good standing as a foreign limited partnership (in the case of Star
Gas), corporation (in the case of Star/Petro) or limited liability company (in
the case of the General Partner) in all jurisdictions in which the nature of
their respective activities or the character of the properties they own, lease
or use makes such qualification or registration necessary and in which the
failure so to qualify or to be so registered would have a Material Adverse
Effect (and the only such jurisdictions are Connecticut, Indiana, Illinois,
Kentucky, Maine, Massachusetts, Michigan, New Hampshire, New Jersey, New York,
Ohio, Pennsylvania, Rhode Island and West Virginia).  Our opinion as to due
incorporation, good standing and foreign qualification is based in each instance
solely on certificates received from appropriate state officials.

      2.  The execution, delivery and performance by each of the Loan Parties of
each of the Operative Agreements to which it is a party and the consummation of
the Transaction (a) have been duly authorized by all requisite action and (b)
will not (i) violate (A) any provision of law, statute, rule or regulation, (B)
the agreements of limited partnership, articles of incorporation, certificate of
formation or other constitutive documents or by-laws of the Loan Parties, (C)
any order of any Governmental Authority or (D) any provision of the credit
agreement and note agreements set forth on Schedule 1 hereto and any other
material indenture, agreement or other instrument to which any of the Loan
Parties is a party or by which any of them or any of their property is bound and
known to us; however, we express no opinion as to compliance with financial
covenants, (ii) be in conflict with, result in a breach of or constitute (alone
or with notice or lapse of time or both) a default or give rise to increased,
additional, accelerated or guaranteed rights of any Person under any such
material indenture, agreement or other instrument or (iii) except for the Liens
of the Collateral Documents, result in the creation or imposition of any Lien
upon or with respect to any property or assets owned upon the consummation of
the Transaction by either of the Obligors.

      3.  (a)  Each of the Operative Agreements has been duly executed and
delivered by each Loan Party that is a party thereto, and in each case each
Operative Agreement is a legal, valid and binding obligation of whichever of the
Loan Parties are parties thereto and is enforceable against each such Loan Party
in accordance with its terms.

      4.  No order, consent, approval, license, authorization, or validation of,
or filing, recording or registration with, or exemption by, (a) any Governmental
Authority, pursuant to any presently existing law or regulation of the United
States of America or the State of New York or pursuant to the Delaware Revised
Uniform Limited Partnership Act (6 Del. C. B7-101, et seq.), the Delaware
Limited Liability Company Act or the Minnesota Business Corporation Act, (b) to

                                     B1-2

<PAGE>

our knowledge, any creditor, (c) the holder of any equity interests of either
Obligor, any of the other Loan Parties or any Affiliate thereof or (d) to our
knowledge, any other Person, is or will be required in connection with the
Transaction or the performance by either Obligor or any of the other Loan
Parties of the Note Agreement or the Operative Agreements to which it is a
party, except those as to which the failure to obtain will not have a Material
Adverse Effect on the financial condition of the Loan Parties or the
Transaction.

      5.  To our knowledge, there are no actions, suits or proceedings pending
or threatened against any of the Loan Parties or involving the Assets.

      6.  Neither of the Obligors is an "investment company" or a company
"controlled" by an "investment company," within the meaning of the Investment
Company Act of 1940, as amended.

      7.  Neither of the Obligors is a "holding company," or a "subsidiary
company" of a "holding company," or an "affiliate" of a "holding company" or of
a "subsidiary company" of a "holding company" within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

      8.  The issuance, sale and delivery of the Mortgage Notes and the payment
of interest and principal on the Mortgage Notes and the Make Whole Amount on the
Mortgage Notes do not give rise to any state taxes, assessments or other
charges, except that we express no opinion with respect to income taxes or
franchise taxes.  No taxes or other impositions of the State of New York, or any
jurisdiction therein, will be imposed upon, or be payable by, the Trustee or any
Purchaser as a precondition to the enforcement of its rights and remedies under
any of the Collateral Documents.

      9.  The offer, issue, sale and delivery of the Mortgage Notes under the
circumstances contemplated by the Note Agreement constitute exempt transactions

     Attached hereto is the opinion of our firm dated December 20, 1995; you are
entitled to rely on the opinions in paragraphs 3(b), 8 and 10 set forth therein,
subject to the assumptions and qualifications therein contained.

     The opinions herein expressed are limited in all respects solely to the
matters governed by the internal laws of the State of New York, the General
Corporation Law of the State of Minnesota, the Delaware Limited Liability
Company Act, the Delaware Revised Uniform Limited Partnership Act and the
Federal laws of the United States of America.

     The opinions herein expressed are subject to and affected by the following:

            (a) Applicable bankruptcy, insolvency, reorganization, receivership,
     moratorium, and assignment for the benefit of creditors' laws and other
     laws affecting the rights and remedies of creditors generally, including
     without limitation, laws regarding fraudulent transfers, fraudulent
     conveyances, preferences, avoidance, marshalling of assets, automatic stay
     and turn-over;

            (b) General principles of equity, including without limitation those
     governing the availability of equitable remedies, affording equitable
     defenses, requiring good faith, fair dealing and reasonableness in the
     performance and enforcement of a contract and affording defenses based upon
     unconscionability, lack of notice, impracticability or impossibility of
     performance;

            (c) Matters relating to election of remedies, the limits of
     severability, opportunity to cure, limitations on the enforceability of
     indemnification, contribution or exculpation provisions under applicable
     securities laws or which are in violation of public policy;

            (d) Certain of the remedial provisions of each Mortgage and the
     Security Agreements may be further limited or rendered unenforceable by
     applicable law, but such law would not make the remedies provided
     thereunder which are otherwise enforceable inadequate for the practical
     realization of the benefits purported to be provided thereunder, taken as a
     whole, except for the consequences of procedural or other delays;

            (e) This Opinion Letter is predicated solely upon laws and
     regulations in existence as of the present date and as they presently apply
     and to the facts as they presently exist.  We assume no obligation to
     revise or supplement this opinion if the present laws are changed by
     legislative action, juridical decision or otherwise;

            (f) The qualification of any opinion herein by use of the words "to
     our knowledge" or similar words means the actual knowledge of those
     attorneys of the undersigned who have represented the Loan Parties
     generally or in connection with the Transaction, without independent
     investigation.  We have relied solely upon the examination and inquiries
     recited herein and have not undertaken any investigation to

                                     B1-4

<PAGE>

     determine the existence or absence of such matters, documents or facts and
     no inference as to our actual knowledge should be drawn from the fact of
     our representation of the Loan Parties, or otherwise.  Alan Shapiro, a
     partner of this law firm, is an Assistant Secretary of Star Gas
     Corporation and of its corporate affiliates.  Knowledge obtained by him in
     his corporate capacity (other than actual knowledge) may not be imputed to
     the Firm.

            (g) This Opinion Letter is limited to the matters set forth herein
     and no opinion is intended to be implied or inferred beyond those expressly
     stated herein.  We have not been asked, and we do not undertake, to render
     any opinion with respect to any matters except as expressly set forth
     herein or to advise you in any matters that may hereinafter be brought to
     our attention.

     This Opinion Letter is based upon the following assumptions:

            (a) You have and will continue to satisfy those legal requirements
     that are uniquely applicable to you to the extent necessary to make the
     Operative Agreements enforceable.

            (b) The parties have complied and will continue to comply with all
     legal requirements pertaining to their status in New York, as such status
     relates to their rights to enforce the Note Agreement and the other
     Operative Agreements.

            (c) There has not been any mutual mistake of fact or
     misunderstanding, fraud, duress or undue influence.

            (d) The conduct of the parties has complied with any requirement of
     good faith, fair dealing and conscionability.

            (e) The parties have acted in good faith and without notice of any
     defense against the enforcement of any rights created under the Note
     Agreement and the other Operative Agreements.

            (f) Each party holds requisite title and rights to any property
     which is the subject of the Note Agreement and the other Operative
     Agreements.

            (g) As to Operative Agreements which are not governed by New York
     law, that such Operative Agreements would be valid and binding if they
     would be valid and binding under the laws of the State of New York.

To the Parties named in
  Schedule I attached hereto

    Re:  $12,500,000 8.67% First Mortgage Notes, Series A, due March 30, 2012
         $15,000,000 8.72% First Mortgage Notes, Series B, due March 30, 2015
                                         of
                     Star Gas Propane, L.P. and Star/Petro, Inc.
         --------------------------------------------------------------------

Ladies and Gentlemen:

     We have acted as special counsel to you (the "Purchasers") in connection
with the execution and delivery of the Note Agreement, dated as of March 30,
2000 (the "Note Agreement"), between Star Gas Propane, L.P., a Delaware limited
partnership ("Star Gas"), Star/Petro, Inc., a Minnesota corporation
("Star/Petro"; and together with Star Gas, the "Obligors"), and you, and the
issuance and sale by the Obligors of $27,500,000 aggregate principal amount of
their First Mortgage Notes comprised of $12,500,000 aggregate principal amount
if the 8.67% First Mortgage Notes, Series A, due March 30, 2012 and $15,000,000
aggregate principal amount of the 8.72% First Mortgage Notes, Series B, due
March 30, 2015 (collectively, the "Notes").  Capitalized terms used in this
opinion without definition have the respective meanings specified in the Note
Agreement.  Star Gas, Star Gas LLC, a Delaware limited liability company (the
"General Partner"), and Star/Petro, are collectively referred to as the "Loan
Parties."

     In that connection, we have examined the following:

            (a)  The Note Agreement;

            (b) A copy of the Certificate of Limited Partnership of Star Gas,
     the Certificate of Formation of the General Partner, and the Articles of
     Incorporation of Star/Petro and all amendments thereto certified by the
     Secretary of State of the State of organization of such Loan Party and the
     Certificate of the Secretary of State of the State of organization of such
     Loan Party evidencing that such Loan Party is in good standing in such
     state (each a "Good Standing Certificate");

            (c) A copy of the Limited Partnership Agreement of Star Gas, the
     limited liability company agreement of the General Partner and the By-laws
     of Star/Petro, as amended to the date hereof, and a copy of the resolutions
     adopted by each Loan Party with respect to the authorization of the Note
     Agreement, the issuance, sale and delivery of the Notes and related
     matters, each as certified by the Secretary of each Loan Party;

                                  Exhibit B2
                             (to Note Agreement)

<PAGE>

            (d) The opinion of Phillips Nizer Benjamin Krim & Ballon LLP,
     special counsel to the Loan Parties, dated the date hereof and delivered
     responsive to Section 4.4(a) of the Note Agreement;

            (e) The Notes delivered on the date hereof;

            (f) Such certificates of officers of each Loan Party and of public
     officials as we have deemed necessary to give the opinions hereinafter
     expressed; and

            (g) Such other documents and matters of law as we have deemed
     necessary to give the opinions hereinafter expressed.

     We believe that the opinion referred to in clause (d) above is satisfactory
in scope and form and that you are justified in relying thereon.  Our opinion as
to matters referred to in paragraph 1 below is based solely upon an examination
of the Certificate of Limited Partnership, Certificate of Formation or Articles
of Incorporation, as the case may be, the Limited Partnership Agreement, limited
liability company agreement or By-laws, as the case may be, and the Good
Standing Certificate of each Loan Party and the limited partnership law, limited
liability company law or general business law of the State of organization of
such Loan Party.  We have also relied, as to certain factual matters, upon
appropriate certificates of public officials and officers of each Obligor and
upon representations of each Obligor and you delivered in connection with the
issuance and sale of the Notes.

     Based upon the foregoing, we are of the opinion that:

            1. Each of Star Gas, Star/Petro and the General Partner is a limited
     partnership (in the case of Star Gas), a corporation (in the case of
     Star/Petro) or a limited liability company (in the case of the General
     Partner) validly existing and in good standing under the laws of the
     jurisdiction of its organization and each Loan Party has the organizational
     power and the organizational authority to execute and deliver the Note
     Agreement and to issue the Notes.

            2. The Note Agreement has been duly authorized by all necessary
     organizational action on the part of each Obligor, has been duly executed
     and delivered by each Obligor and constitutes the legal, valid and binding
     contract of each Obligor enforceable against each Obligor in accordance
     with its terms, subject to bankruptcy, insolvency, fraudulent conveyance
     and similar laws affecting creditors' rights generally, and general
     principles of equity (regardless of whether the application of such
     principles is considered in a proceeding in equity or at law).

            3. The Notes have been duly authorized by all necessary
     organizational action on the part of each Obligor, and the Notes being
     delivered on the date hereof have been duly executed and delivered by each
     Obligor and constitute the legal, valid and binding obligations of each
     Obligor enforceable against each Obligor in accordance with their terms,
     subject to bankruptcy, insolvency, fraudulent conveyance and similar laws
     affecting

                                    B-2-2

<PAGE>

     creditors' rights generally, and general principles of equity (regardless
     of whether the application of such principles is considered in a
     proceeding in equity or at law).

            4. The issuance, sale and delivery of the Notes under the
     circumstances contemplated by the Note Agreement do not, under existing
     law, require the registration of the Notes under the Securities Act of
     1933, as amended, or the qualification of an indenture under the Trust
     Indenture Act of 1939, as amended.

     Our opinion is limited to the laws of the State of New York, the General
Corporation Law of the State of Minnesota, the Delaware Limited Liability
Company Act, the Delaware Revised Uniform Limited Partnership Act and the
Federal laws of the United States of America and we express no opinion on the
laws of any other jurisdiction.

                                 Respectfully submitted,

                                    B-2-3

$___________________

     For Value Received, the undersigned, _______________________, a
____________ organized under the laws of the State of ________________________
(the "Debtor"), hereby promises to pay to the order of [General Partner/Public
Partnership/Borrower], a ____________ organized under the laws of the State of
__________________ (the "Subordinated Creditor"), at 2187 Atlantic Street,
Stamford, CT 06902, (i) the principal amount of $__________, or, if less, the
aggregate unpaid principal amount of each loan or advance made by the
Subordinated Creditor to the Debtor at any time upon demand by the Subordinated
Creditor in lawful money of the United States of America in immediately
available funds and (ii) interest from the date hereof on the principal amount
hereof from time to time outstanding, in like funds, at a rate per annum equal
to the rate applicable at such time to ABR Tranche A Revolving Loans pursuant to
Section 2.06 of the Credit Agreement referred to below.  Indebtedness of the
Debtor to the Subordinated Creditor is hereinafter referred to as "Subordinated
Debt." This Note may be prepaid in whole or in part at any time without premium
or penalty.  Amounts prepaid on this Note may be reborrowed.  Terms used herein
and not otherwise defined herein shall have the meanings assigned to them in
Annex A attached hereto.

     The Debtor promises to pay interest, on demand, on any overdue principal
and, to the extent permitted by law, overdue interest from their due dates at
the rate per annum applicable pursuant to the preceding paragraph, plus 2.00%.

     The Debtor and any and all sureties, guarantors and endorsers of this Note
and all other parties now or hereafter liable hereon, severally waive grace,
presentment for payment, protest, notice of any kind (including notice of
dishonor, notice of protest, notice of intent to accelerate and notice of
acceleration) and diligence in collecting and bringing suit against any party
hereto, and agree (a) to all extensions and partial payments, with or without
notice, before or after maturity, (b) to any substitution, exchange or release
of any security now or hereafter given for this Note, (c) to the release of any
party primarily or secondarily liable hereon and (d) that it will not be
necessary for the Subordinated Creditor or any of its successors or assigns, in
order to enforce payment of this Note, to first institute or exhaust their
remedies against the Debtor or any other party liable therefor or against any
security for this Note.  The nonexercise by the holder of any of its rights
hereunder in any particular instance shall not constitute a waiver thereof in
that or any subsequent instance.

     The outstanding principal balance of the loans and advances evidenced by
this Note shall automatically become immediately due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are
expressly waived by the Debtor, upon the occurrence of an Event of Default under
the Credit Agreement.

     The Subordinated Creditor and the Debtor agree that the Subordinated Debt
is and shall be subordinate, to the extent and in the manner hereinafter set
forth, to the prior payment in full of

                                     C-2

<PAGE>

(a) the Borrower obligations in respect of the due and punctual payment of
principal of and interest on the Loans and all amounts drawn under the Letters
of Credit, when and as due, whether at maturity, by acceleration, upon one or
more dates set for prepayment or otherwise, (b) all Fees, expenses, indemnities
and expense reimbursement obligations of the Borrower under the Credit
Agreement or any other Loan Document, (c) all other obligations, monetary or
otherwise, of the Borrower or any other Loan Party under any Loan Document to
which it is a party, in each case, whether now owing or hereafter existing, (d)
the principal of and premium, if any, and interest on the Mortgage Notes, (e)
all other Indebtedness and obligations of the Borrower under the Note
Agreements, the Mortgage Notes, the Trust Agreement and the Collateral
Documents and (f) all Indebtedness of the Borrower and the Restricted
Subsidiaries (i) permitted to be incurred under Sections 6.01(b), (f) and (i)
of the Credit Agreement and Sections 10.1(b), (f) and (i) of the Note
Agreements and (ii) permitted to be secured in accordance with Section 6.02(g)
or (h) of the Credit Agreement and Section 10.2(h) or (i) of the Note
Agreements (such obligations, being, collectively, the "Senior Debt"). The
Senior Debt shall not be deemed to have been paid in full until (a) all of the
Senior Debt shall have been indefeasibly paid in full in cash, (b) the
Commitments have been terminated and (c) all Letters of Credit have been
cancelled or have expired and all Letter of Credit Disbursements have been
indefeasibly reimbursed in full in cash ("Payment in Full").

     In the event of any dissolution, winding up, liquidation, arrangement,
reorganization, adjustment, protection, relief or composition of the Debtor or
its debts, whether voluntary or involuntary, in any bankruptcy, insolvency,
arrangement, reorganization, receivership, relief or other similar case or
proceeding under any Federal or state bankruptcy or similar law or upon an
assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Debtor or otherwise, the Secured Parties shall be
entitled to receive Payment in Full of the Senior Debt before the Subordinated
Creditor having any Subordinated Debt outstanding to the Debtor is entitled to
receive any payment of all or any of such Subordinated Debt, and any payment or
distribution of any kind (whether in cash, property or securities) that
otherwise would be payable or deliverable upon or with respect to such
Subordinated Debt in any such case, proceeding, assignment, marshalling or
otherwise (including any payment that may be payable by reason of any other
indebtedness of the Debtor being subordinated to payment of the Subordinated
Debt) shall be paid or delivered directly to the Trustee under the Trust
Agreement for the account of the Secured Parties for application (in the case of
cash) to, or as collateral (in the case of non-cash property or securities) for,
the payment or prepayment of the Senior Debt until the Senior Debt shall have
been indefeasibly paid in full in cash ("Paid in Full").

     In the event that (i) any occurrence and continuation of a default in the
payment of any principal of, interest on or fees relating to any of the Senior
Debt or (ii) any judicial proceeding shall be pending with respect to any
default or event of default with respect to any of the Senior Debt, then no
payment (including any payment that may be payable by reason of any other
indebtedness of the Debtor being subordinated to payment of the Subordinated
Debt) shall be made by or on behalf of the Debtor for or on account of any
Subordinated Debt, and the Subordinated Creditor shall not take or receive from
the Debtor, directly or indirectly, in cash or other property or by set-off or
in any other manner, including, without limitation, from or by way of
collateral, payment of all or any of the Subordinated Debt.

                                     C-3

<PAGE>

     In the event that any default or event of default (other than as referred
to in clauses (i) and (ii) of the preceding paragraph) with respect to any of
the Senior Debt shall have occurred and be continuing and the Trustee under the
Trust Agreement gives written notice thereof to the Subordinated Creditor, then
no payment (including any payment that may be payable by reason of any other
indebtedness of the Debtor being subordinated to payment of the Subordinated
Debt specified in such notice) shall be made by or on behalf of the Debtor for
or on account of the Subordinated Debt specified in such notice, and the
Subordinated Creditor shall not take or receive from the Debtor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
including, without limitation, from or by way of collateral, payment of all or
any of the Subordinated Debt specified in such notice, unless and until the
Senior Debt shall have been Paid in Full.

     In the event that any Subordinated Debt is declared due and payable before
its stated maturity, the Secured Parties shall be entitled to receive Payment in
Full of all amounts due or to become due on or in respect of all the Senior Debt
before the Subordinated Creditor is entitled to receive any payment (including
any payment which may be payable by reason of the payment of any other
indebtedness of the Debtor being subordinated to the payment of the Subordinated
Debt) by the Debtor on account of the Subordinated Debt.

     The Subordinated Creditor agrees as follows:

            (a) If any proceeding referred to above is commenced by or against
     the Debtor,

                  (i) the Trustee under the Trust Agreement is hereby
          irrevocably authorized and empowered (in its own name or in the name
          of the Subordinated Creditor having Subordinated Debt outstanding to
          the Debtor or otherwise), but shall have no obligation, to demand, sue
          for, collect and receive every payment or distribution referred to
          above and give acquittance therefor and to file claims and proofs of
          claim and take such other action (including, without limitation,
          voting such Subordinated Debt or enforcing any security interest or
          other lien securing payment of such Subordinated Debt) as it may deem
          necessary or advisable for the exercise or enforcement of any of the
          rights or interests of the Secured Parties hereunder; and

                  (ii) the Subordinated Creditor having Subordinated Debt
          outstanding to the Debtor shall duly and promptly take such action as
          the Trustee may request (A) to collect such Subordinated Debt for the
          account of the Secured Parties and to file appropriate claims or
          proofs of claim in respect of such Subordinated Debt, (B) to execute
          and deliver to the Trustee such powers of attorney, assignments, or
          other instruments as the Trustee may request in order to enable the
          Trustee to enforce any and all claims with respect to, and any
          security interests and other liens securing payment of, such
          Subordinated Debt and (C) to collect and receive any and all payments
          or distributions which may be payable or deliverable upon or with
          respect to such Subordinated Debt.

                                     C-4

<PAGE>

            (b) All payments or distributions upon or with respect to the
     Subordinated Debt which are received by the Subordinated Creditor contrary
     to the provisions hereof shall be received in trust for the benefit of the
     Secured Parties, shall be segregated from other funds and property held by
     the Subordinated Creditor and shall be forthwith paid over to the Trustee
     for the account of the Secured Parties in the same form as so received
     (with any necessary indorsement) to be applied (in the case of cash) to, or
     held as collateral (in the case of non-cash property or securities) for,
     the payment or prepayment of the Senior Debt in accordance with the terms
     of the Credit Agreement.

            (c) The Trustee is hereby authorized to demand specific performance
     of this Agreement, whether or not the Debtor shall have complied with any
     of the provisions hereof applicable to them, at any time when the
     Subordinated Creditor shall have failed to comply with any of the
     provisions hereof applicable to it.  The Subordinated Creditor hereby
     irrevocably waives any defense based on the adequacy of a remedy at law,
     which might be asserted as a bar to such remedy of specific performance.

     The Subordinated Creditor agrees that, so long as the Senior Debt shall not
have been Paid in Full, the Subordinated Creditor will not sue for payment of
all or any of the Subordinated Debt, or commence, or join with any creditor
other than the Secured Parties in commencing, or directly or indirectly cause
the Debtor to commence, or assist the Debtor in commencing, any proceeding
referred to above.

     The Subordinated Creditor agrees that no payment or distribution to the
Secured Parties pursuant to the provisions hereof shall entitle the Subordinated
Creditor to exercise any right of subrogation in respect thereof until the
Senior Debt shall have been Paid in Full.

     The Subordinated Creditor will not:

            (a) cancel or otherwise discharge any of the Subordinated Debt owing
     to it (except upon Payment in Full thereof), convert or exchange any of
     such Subordinated Debt into or for any other indebtedness or equity
     interest or subordinate any of the Subordinated Debt to any indebtedness of
     the Debtor other than the Senior Debt;

            (b) sell, assign, pledge, encumber or otherwise dispose of any of
     the Subordinated Debt owing to it; or

            (c) permit the terms of any of the Subordinated Debt owing to it to
     be changed in such a manner as to have, directly or indirectly, in the
     reasonable judgment of the Trustee, an adverse effect upon the rights or
     interests of the Secured Parties hereunder.

     The Subordinated Creditor shall promptly notify the Trustee of the
occurrence of any default under the Subordinated Debt owing to it.

     The Debtor agrees that it will not make any payment of any of the
Subordinated Debt, or take any other action, in contravention of the provisions
hereof.

                                     C-5

<PAGE>

     All rights and interests of the Secured Parties hereunder, and all
agreements and obligations of the Subordinated Creditor and the Debtor
