                               FINANCING AGREEMENT


                  This FINANCING AGREEMENT, dated as of November 5, 1997 (the
"Agreement"), is between AmeriGas Propane, Inc., a Pennsylvania corporation
("AGP"), and AmeriGas Propane, L.P., a Delaware limited partnership ("APLP").


                                   BACKGROUND

                  A. AGP is the sole general partner of APLP.

                  B. AGP has agreed to make available to APLP a revolving credit
facility, upon the terms and conditions set forth in this Agreement, to finance
APLP's working capital, capital expenditures and interest and distribution
expenses.

                  C. Capitalized terms used herein and not otherwise defined
shall have the respective meanings assigned to them in that certain Amended and
Restated Credit Agreement dated as of September 15, 1997 among AGP, APLP,
Petrolane Incorporated, Bank of America National Trust and Savings Association,
as Agent, First Union Capital Markets Corp., as Syndication Agent, and the other
financial institutions party thereto (the "Credit Agreement").

                  NOW, THEREFORE, in consideration of the premises and covenants
contained herein, and intending to be legally bound hereby, the parties hereto
agree as follows:

                  1. Credit Line Terms.

                           (a) Credit Limit. AGP agrees, on the terms and
conditions set forth herein, to make loans ("Loans") to APLP from time to time
on any Business Day during the period from the date hereof to the Revolving
Termination Date, in an aggregate principal amount not to exceed at anytime
outstanding of $20,000,000 (the "Commitment"). Subject to the other terms and
conditions hereof, APLP may borrow under this Section 1(a), prepay under Section
1(d) and reborrow under this Section 1(a). The Commitment shall automatically be
terminated (i) upon the occurrence of an Event of Default (as defined in Section
4 below) unless waived in writing by AGP or (ii) if AGP is no longer the sole
general partner of APLP. Upon the termination of the Commitment, subject to the
provisions of Section 15 below, APLP shall pay to AGP all amounts owing or
payable under this Agreement, without presentment, demand, protest or any other
notice of any kind, all of which are expressly waived by APLP.
<PAGE>   2
                           (b) Procedure for Borrowing. Each borrowing by APLP
pursuant to Section 1(a) shall be made upon APLP's written notice delivered to
AGP one Business Day prior to the requested borrowing date specifying the
requested borrowing amount and date. All advances by AGP hereunder shall be
noted on the Master Promissory Note provided for in Section 3 hereof.

                           (c) Voluntary Termination or Reduction of Commitment.
APLP may, upon prior written notice to AGP, terminate the Commitment or
permanently reduce the Commitment by an aggregate minimum amount of $1,000,000
or any multiple of $1,000,000 in excess thereof. At no time shall the amount of
outstanding Loans exceed the amount of the Commitment.

                           (d) Optional Prepayment. APLP may at anytime, upon
prior notice to AGP, prepay Loans, together with all accrued and unpaid interest
thereon, in whole or in part.

                           (e) Repayment. APLP shall repay to AGP on the
Revolving Termination Date the aggregate principal amount of Loans outstanding
on such date, together with all accrued and unpaid interest thereon.

                           (f) Interest. Each Loan shall bear interest on the
outstanding principal amount thereof from the applicable borrowing date to the
one month anniversary of the borrowing date at a rate per annum equal to the
Offshore Rate, with an Interest Period of one month, on such borrowing date,
plus the Applicable Margin for Offshore Rate Loans - Revolving Loans (the
"Interest Rate"). On each one month anniversary of any Loan (the "Reset Date"),
such Loan shall bear interest on the outstanding principal amount thereof until
the next one month anniversary date at a rate per annum equal to the Interest
Rate on the Reset Date. The Interest Rate shall change during any Interest
Period as a result of changes in the Applicable Margin. Interest on each Loan
shall be paid in arrears on the last day of each month and on the Revolving
Termination Date.

                           (g) Default Interest. During the existence of any
Event of Default, interest shall be paid upon demand by AGP. The foregoing
notwithstanding, if any amount of principal of or interest on any Loan, or any
other amount payable hereunder, is not paid in full when due, APLP agrees to pay
interest on such unpaid amount, from the date such amount becomes due to the
date such amount is paid in full, and after as well as before any entry of
judgment thereon to the extent permitted by law, payable on demand (but not more
frequently than once per week), at a fluctuating rate per annum equal to the
Base Rate plus 2%.

                           (h) Facility Fees. APLP shall pay to AGP on the last
day of each calendar quarter a facility fee from the date hereof through the
Revolving Termination Date, on the daily average amount of the Commitment
(whether or not used), at the rate per annum set forth below for each pricing
tier as such pricing tier is applicable.

                           (k) Computation of Fees and Interest. All

Master Promissory Note, substantially in the form attached hereto as Exhibit A;

indebtedness (principal and interest) then outstanding to AGP hereunder.

                  4. Events of Default. It shall be an "Event of Default" under
this Agreement if (a) APLP shall fail to pay to AGP any amount of principal of

                  15. Subordination. (a) The indebtedness ("Subordinated Debt")
evidenced by this Agreement is subordinate and junior in right of payment to all
Senior Debt (as defined in subdivision (b) hereof) of APLP to the extent
provided herein.

                  (b) For all purposes of these subordination provisions the
term "Senior Debt" shall mean all principal of and Make Whole Amount, if any,
and interest on (i) APLP's First Mortgage Notes, Series A through C, originally
issued in the aggregate principal amount of $518,000,000, pursuant to separate
Note Agreements, dated as of April 12, 1995 as amended, between APLP, AmeriGas
Propane, Inc., a Pennsylvania corporation and Petrolane Incorporated, a
California corporation and the institutional investors listed on Schedule I
thereto (and any notes issued in substitution therefor), (ii) those obligations
outstanding under the Credit Agreement, and (iii) all other indebtedness of APLP
for borrowed money unless, under the instrument evidencing the same or under
which the same is outstanding, it is expressly provided that such other
indebtedness is junior and subordinate to other indebtedness and obligations of
APLP. The Senior Debt shall continue to be Senior Debt and entitled to the


                                      -6-
<PAGE>   7
benefits of these subordination provisions irrespective of any amendment,
modification or waiver of any term of or extension or renewal of the Senior
Debt.

                  (c) Upon the happening of an event of default with respect to
any Senior Debt, as defined therein or in the instrument under which the same is
outstanding, which occurs at the maturity thereof or which automatically
accelerates or permits the holders thereof to accelerate the maturity thereof,
then, unless and until such event of default shall have been remedied or waived
or shall have ceased to exist, no direct or indirect payment (in cash, property
or securities or by set-off or otherwise) other than Permitted Payments shall be
made on account of the principal of, or premium, if any, or interest on any
Subordinated Debt, or as a sinking fund for the Subordinated Debt, or in respect
of any redemption, retirement, purchase or other acquisition of any of the
Subordinated Debt. For purposes of these subordination provisions, "Permitted
Payments" shall mean (i) payments of in-kind interest and (ii) payments of
Permitted Securities (as defined below) pursuant to paragraph (d) below.

                  (d) In the event of

                  (i)      any insolvency, bankruptcy, receivership,
                           liquidation, reorganization, readjustment,
                           composition or other similar proceeding relating to
                           APLP, its creditors as such or its property,

                  (ii)     any proceeding for the liquidation, dissolution or
                           other winding-up of APLP, voluntary or involuntary,
                           whether or not involving insolvency or bankruptcy
                           proceedings,

                  (iii)    any assignment by APLP for the benefit of creditors,
                           or

                  (iv)     any other marshalling of the assets of APLP,

all Senior Debt (including any interest thereon accruing at the legal rate after
the commencement of any such proceedings and any additional interest that would
have accrued thereon but for the commencement of such proceedings) shall first
be paid in full before any payment or distribution, whether in cash, securities
or other property (other than Permitted Payments), shall be made to any holder
of any Subordinated Debt on account of any Subordinated Debt. Any payment or
distribution, whether in cash, securities or other property (other than
securities ("Permitted Securities") of APLP or any other entity provided for by
a plan of reorganization or readjustment the payment of which is subordinate, at
least to the 


                                      -7-
<PAGE>   8
extent provided in these subordination provisions with respect to Subordinated
Debt, to the payment of all Senior Debt at the time outstanding and to any
securities issued in respect thereof under any such plan of reorganization or
readjustment), which would otherwise (but for these subordination provisions) be
payable or deliverable in respect of this Subordinated Debt shall be paid or
delivered directly to the holders of Senior Debt in accordance with the
priorities then existing among such holders until all Senior Debt (including any
interest thereon accruing at the legal rate after the commencement of any such
proceedings and any additional interest that would have accrued thereon but for
the commencement of such proceedings) shall have been paid in full.

                  (e) In the event that any holder of Subordinated Debt shall
have the right to declare any Subordinated Debt due and payable as a result of
the occurrence of any one or more defaults in respect thereof, under
circumstances when the terms of subdivision (d) above are not applicable, such
holder shall not declare such Subordinated Debt due and payable or otherwise to
be in default and, solely in its capacity as a holder of such Subordinated Debt,
shall take no action at law or in equity in respect of any such default unless
and until all Senior Debt shall have been paid in full.

                  (f) If any payment or distribution of any character or any
security, whether in cash, securities or other property (other than Permitted
Payments), shall be received by a holder of Subordinated Debt in contravention
of any of the terms hereof before all the Senior Debt shall have been paid in
full, such payment or distribution or security shall be received in trust for
the benefit of, and shall be paid over or delivered and transferred to, the
holders of the Senior Debt at the time outstanding in accordance with the
priorities then existing among such holders for application to the payment of
all Senior Debt remaining unpaid, to the extent necessary to pay all such Senior
Debt in full. In the event of the failure of any holder of any Subordinated Debt
to endorse or assign any such payment, distribution or security, each holder of
Senior Debt is hereby irrevocably authorized to endorse or assign the same.

                  (g) No present or future holder of any Senior Debt shall be
prejudiced in the right to enforce subordination of Subordinated Debt by any act
or failure to act on the part of APLP. Nothing contained herein shall impair, as
between APLP and the holder of this Subordinated Debt, the obligation of APLP to
pay to the holder hereof the principal hereof and interest hereon as and when
the same shall become due and payable in accordance with the terms hereof, or
prevent the holder of any Subordinated Debt from exercising all rights, powers
and remedies otherwise permitted by applicable law or hereunder upon a default
or event of default hereunder, all subject 


                                      -8-
<PAGE>   9
to the rights of the holders of the Senior Debt to receive cash, securities or
other property (other than Permitted Payments) otherwise payable or deliverable
to the holders of Subordinated Debt.

                  (h) Upon the payment in full of all Senior Debt, the holders
of Subordinated Debt shall be subrogated to all rights of any holders of Senior
Debt to receive any further payments or distributions applicable to the Senior
Debt until the Subordinated Debt shall have been paid in full, and, for purposes
of such subrogation, no payment or distribution received by the holders of
Senior Debt of cash, securities or other property to which the holders of the
Subordinated Debt would have been entitled except for these subordination
provisions shall, as between APLP and its creditors other than the holders of
Subordinated Debt, on the one hand, and the holders of Subordinated Debt, on the
other, be deemed to be a payment or distribution by APLP to or on account of
Senior Debt.


                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed as of the date first above written.
