                                AMENDED AGREEMENT

         Amended Agreement ("Agreement") made as of July 27, 1999, among UGI
Utilities, Inc., a Pennsylvania corporation (the "Company"), its corporate
parent, UGI Corporation, a Pennsylvania corporation ("UGI") and Robert J. Chaney
(the "Employee").

         WHEREAS, UGI and the Employee entered into an Agreement as of June 28,
1996, to provide for certain payments to be made to the Employee in the event of
a change of control of UGI; and

         WHEREAS, UGI and the Employee amended the Agreement as of July 29, 1997
and February 23, 1999, as permitted by Section 16 of the Agreement; and

         WHEREAS, the board of directors of the Company has approved, as of July
27, 1999, the assumption by the Company of all of the liabilities and
obligations of UGI under the Amended Change of Control Agreement dated as of
February 23, 1999 between UGI and the Employee, except for obligations, if any,
arising under Section 5 thereof; and

         WHEREAS, the Company and the Employee wish to provide for such
assumption; and

         WHEREAS, the Company and the Employee also wish to amend the Agreement,
as permitted by Section 16; and

         WHEREAS, the Company considers it essential to foster the employment of
well qualified key management personnel, and, in this regard, the board of
directors of the Company recognizes that, as is the case with many corporations,
the possibility of a

<PAGE>

change in control affecting UGI or the Company may exist and that such
possibility, and the uncertainty and questions which it may raise among
management, may result in the departure or distraction of key management
personnel to the detriment of the Company; and

         WHEREAS, the board of directors of the Company has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of key members of the Company's management to their
assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of UGI or the
Company, although no such change is now contemplated; and

         WHEREAS, in order to induce the Employee to remain in the employ of the
Company, the Company agrees that the Employee shall receive the compensation set
forth in this Agreement in the event his employment with the Company is
terminated subsequent to a "Change of Control," as defined in Section 1 hereof,
as a cushion against the financial and career impact on the Employee of any such
Change of Control;

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, the Company hereby assumes and
agrees to discharge and perform all obligations and liabilities of UGI under the
Amended Agreement dated as of February 23, 1999 between UGI and the Employee,
except for obligations, if any, arising under Section 5 thereof; and UGI hereby
agrees to perform all its liabilities and obligations under Section 5 hereof;
and the parties hereto agree that the Agreement shall read as follows:

beginning of such period whose election or nomination for election by the UGI
stockholders was approved by a vote of at least a majority of the directors then
comprising the Incumbent UGI Board shall be considered as though such individual
were a member of the Incumbent UGI Board, but excluding, for this purpose, any
such individual whose initial assumption of office is in connection with an

(less than 12 months); and

                  (vi)     the Employee being required to undertake business
travel to an extent substantially greater than the Employee's business travel
obligations immediately prior to the Change of Control.

         (h)      "Normal Retirement Date" shall mean the first day of the
calendar month coincident with or next following the Employee's 62nd birthday.

         (i)      "Subsidiary" shall mean any corporation in which the Company,
directly or indirectly, owns at least a 50% interest or an unincorporated entity
of which the Company, directly or indirectly, owns at least 50% of the profits
or capital interests.

         (j)      "Termination Date" shall mean the date of receipt of the
Notice of Termination described in Section 2 hereof or any later date specified
therein, as the case may be.

         (k)      "Termination of Employment" shall mean the termination of the

         2.       Notice of Termination. Any Termination of Employment following
a Change of Control shall be communicated by a Notice of Termination to the

                                      -9-
<PAGE>

other party hereto given in accordance with Section 14 hereof. For purposes of
this Agreement, a "Notice of Termination" means a written notice which (i)
indicates the specific provision in this Agreement relied upon, (ii) briefly
summarizes the facts and circumstances deemed to provide a basis for the
Employee's Termination of Employment under the provision so indicated, and (iii)
if the Termination Date is other than the date of receipt of such notice,
specifies the Termination Date (which date shall not be more than 15 days after
the giving of such notice).

         3.       Severance Compensation upon Termination.

         (a)      Subject to the provisions of Section 11 hereof, in the event
of the Employee's involuntary Termination of Employment for any reason other
than Cause or in the event of a Good Reason Termination, in either event within
three years after a Change of Control, the Company shall pay to the Employee,
upon the execution of a release, in the form required by the Company of its
terminating executives prior to the Change of Control, within 15 days after the
Termination Date (or as soon as possible thereafter in the event that the
procedures set forth in Section 11(b) hereof cannot be completed within 15
days), an amount in cash equal to 1.5 times the Employee's Base Compensation,
subject to customary employment taxes and deductions.

         (b)      In the event the Employee's Normal Retirement Date would occur
prior to 18 months after the Termination Date, the aggregate cash amount
determined as set forth in (a) above shall be reduced by multiplying it by a
fraction, the numerator of which shall be the number of days from the
Termination Date to the Employee's Normal Retirement Date and the denominator of
which shall be 548 days.

                                      -10-
<PAGE>

         4.       Other Payments.

                  The payments due under Section 3 hereof shall be in addition
to and not in lieu of any payments or benefits due to the Employee under any
other plan, policy or program of the Company, and its Subsidiaries or
Affiliates.

         5.       Trust Fund. UGI sponsors an irrevocable trust fund pursuant to
a trust agreement to hold assets to satisfy obligations under this Agreement.
Funding of such trust fund shall be subject to the discretion of the UGI Board
of Directors or the Executive Committee of the UGI Board of Directors, as set
forth in the agreement pursuant to which the fund has been established.

         6.       Enforcement.

         (a)      In the event that the Company shall fail or refuse to make
payment of any amounts due the Employee under Section 3 hereof within the
respective time periods provided therein, the Company shall pay to the Employee,
in addition to the payment of any other sums provided in this Agreement,
interest, compounded daily, on any amount remaining unpaid, from the date
payment is required under Section 3 until paid to the Employee, at the rate from
time to time announced by Mellon Bank, N.A. as its "prime rate" plus 1%, each
change in such rate to take effect on the effective date of the change in such
prime rate.

         (b)      It is the intent of the parties that the Employee not be
required to incur any expenses associated with the enforcement of his rights
under this Agreement by arbitration, litigation or other legal action because
the cost and expense thereof would substantially detract from the benefits
intended to be extended to the Employee hereunder. Accordingly, the Company
shall pay the Employee on demand the amount

                                      -11-
<PAGE>

necessary to reimburse the Employee in full for all reasonable expenses
(including all attorneys' fees and legal expenses) incurred by the Employee in
enforcing any of the obligations of the Company under this Agreement.

         7.       No Mitigation. The Employee shall not be required to mitigate
the amount of any payment or benefit provided for in this Agreement by seeking
other employment or otherwise, nor shall the amount of any payment or benefit
provided for herein be reduced by any compensation earned by other employment or
otherwise.

         8.       Non-exclusivity of Rights. Nothing in this Agreement shall
prevent or limit the Employee's continuing or future participation in or rights
under any benefit, bonus, incentive or other plan or program provided by the
Company, or any of its Subsidiaries or Affiliates, and for which the Employee
may qualify.

         9.       No Set-Off. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim, recoupment, defense or other right which
the Company may have against the Employee or others.

         10.      Taxes. Any payment required under this Agreement shall be
subject to all requirements of the law with regard to the withholding of taxes,
filing, making of reports and the like, and the Company shall use its best
efforts to satisfy promptly all such requirements.

         11.      Certain Increase in Payments.

         (a)      Anything in this Agreement to the contrary notwithstanding, in
the event that it shall be determined that any payment or distribution by the
Company to or

                                      -12-
<PAGE>

for the benefit of the Employee, whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise (a
"Payment"), would constitute an "excess parachute payment" within the meaning of
Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), the
Employee shall be paid an additional amount (the "Gross-Up Payment") such that
the net amount retained by the Employee after deduction of any excise tax
imposed under Section 4999 of the Code, and any federal, state and local income
and employment tax and excise tax imposed upon the Gross-Up Payment shall be
equal to the Payment. For purposes of determining the amount of the Gross-Up
Payment, the Employee shall be deemed to pay federal income tax and employment
taxes at the highest marginal rate of federal income and employment taxation in
the calendar year in which the Gross-Up Payment is to be made and state and
local income taxes at the highest marginal rate of taxation in the state and
locality of the Employee's residence on the Termination Date, net of the maximum
reduction in federal income taxes that may be obtained from the deduction of
such state and local taxes.

         (b)      All determinations to be made under this Section 11 shall be
made by Coopers & Lybrand (or, at the Company's option, the Company's
independent public accountant immediately prior to the Change of Control (the
"Accounting Firm")), which firm shall provide its determinations and any
supporting calculations both to the Company and the Employee within 10 days of
either (i) the Change of Control or (ii) the Termination Date, as the case may
be. Any such determination by the Accounting Firm shall be binding upon the
Company and the Employee. Within five days after the Accounting Firm's
determination, the Company shall pay (or cause to be paid) or

                                      -13-
<PAGE>

distribute (or cause to be distributed) to or for the benefit of the Employee
such amounts as are then due to the Employee under this Agreement.

         (c)      In the event that upon any audit by the Internal Revenue
Service, or by a state or local taxing authority, of the Payment or Gross-Up
Payment, a change is finally determined to be required in the amount of taxes
paid by the Employee, appropriate adjustments shall be made under this Agreement
such that the net amount which is payable to the Employee after taking into
account the provisions of Section 4999 of the Code shall reflect the intent of
the parties as expressed in subsection (a) above, in the manner determined by
the Accounting Firm.

         (d)      All of the fees and expenses of the Accounting Firm in
performing the determinations referred to in subsections (b) and (c) above shall
be borne solely by the Company. The Company agrees to indemnify and hold
harmless the Accounting Firm of and from any and all claims, damages and
expenses resulting from or relating to its determinations pursuant to
subsections (b) and (c) above, except for claims, damages or expenses resulting
from the gross negligence or wilful misconduct of the Accounting Firm, which
firm shall provide its determinations and any supporting calculations both to
the Company and the Employee within 10 days of either (i) the Change of Control
or (ii) the Termination Date, as the case may be. Any such determination by the
Accounting Firm shall be binding upon the Company and the Employee.

         12.      Term of Agreement. The term of this Agreement shall be for
five years from the date hereof and shall be automatically renewed for
successive one-year periods unless the Company notifies the Employee in writing
that this Agreement will not be renewed at least sixty days prior to the end of
the current term; provided, however, that

                                      -14-
<PAGE>

(i) after a Change of Control during the term of this Agreement, this Agreement
shall remain in effect until all of the obligations of the parties hereunder are
satisfied or have expired, and (ii) this Agreement shall terminate if, prior to
a Change of Control, the employment of the Employee with the Company or any of
its Subsidiaries, as the case may be, shall terminate for any reason.

         13.      Successor Company. The Company shall require any successor or
successors (whether direct or indirect, by purchase, merger or otherwise) to all
or substantially all of the business and/or assets of the Company, by agreement
in form and substance satisfactory to the Employee, to acknowledge expressly
that this Agreement is binding upon and enforceable against the Company in
accordance with the terms hereof, and to become jointly and severally obligated
with the Company to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession or
successions had taken place. Failure of the Company to notify the Employee in
writing as to such successorship, to provide the Employee the opportunity to
review and agree to the successor's assumption of this Agreement or to obtain
such agreement prior to the effectiveness of any such succession shall be a
breach of this Agreement. As used in this Agreement, the Company shall mean the
Company as hereinbefore defined and any such successor or successors to its
business and/or assets, jointly and severally.

         14.      Notice. All notices and other communications required or
permitted hereunder or necessary or convenient in connection herewith shall be
in writing and shall be delivered personally or mailed by registered or
certified mail, return receipt requested, or by overnight express courier
service, as follows:

may be, shall designate by notice to the other party hereto in the manner
specified in this Section; provided, however, that if no such notice is given by
the Company following a Change of Control, notice at the last address of the
Company or to any successor pursuant to Section 13 hereof shall be deemed
sufficient for the purposes hereof. Any such notice shall be deemed delivered
and effective when received in the case of personal delivery, five days after
deposit, postage prepaid, with the U.S. Postal Service in the case of registered
or certified mail, or on the next business day in the case of overnight express
courier service.

         15.      Governing Law. This Agreement shall be governed by and
interpreted under the laws of the Commonwealth of Pennsylvania without giving
effect to any conflict of laws provisions.

         16.      Contents of Agreement, Amendment and Assignment. This
Agreement supersedes all prior agreements, sets forth the entire understanding
between the parties hereto with respect to the subject matter hereof and cannot
be changed, modified, extended or terminated except upon written amendment
executed by the Employee and the Chairman of the Company. The provisions of this
Agreement may

                                      -16-
<PAGE>

require a variance from the terms and conditions of certain compensation or
bonus plans under circumstances where such plans would not provide for payment
thereof in order to obtain the maximum benefits for the Employee. It is the
specific intention of the parties that the provisions of this Agreement shall
supersede any provisions to the contrary in such plans, and such plans shall be
deemed to have been amended to correspond with this Agreement without further

of the Company.

equitable remedy such as an injunction, the parties shall be required to have
the dispute, controversy or claim settled by arbitration in Reading,
Pennsylvania, in accordance with the commercial arbitration rules then in effect
of the American Arbitration Association, before one arbitrator who shall be an
executive officer or former executive officer of a publicly traded corporation,
selected by the parties. Any award entered by the arbitrator shall be final,
binding and nonappealable and judgment may be entered thereon by either party in
accordance with applicable law in any court of competent jurisdiction. This
arbitration provision shall be specifically enforceable. The arbitrator shall
have no authority to modify any provision of this Agreement or to award a remedy
for a dispute involving this Agreement other than a benefit specifically
provided under or by virtue of the Agreement. The Company shall be responsible
for all of the fees of the American Arbitration Association and the arbitrator
and any expenses relating to the conduct of the arbitration (including
