                                 UGI CORPORATION
                      2004 OMNIBUS EQUITY COMPENSATION PLAN
                          PERFORMANCE UNIT GRANT LETTER

This PERFORMANCE UNIT GRANT, dated as of January 1, 2004 (the "Date of Grant"),
is delivered by UGI Corporation ("UGI") to _____________ (the "Participant").

                                    RECITALS

      The UGI Corporation 2004 Omnibus Equity Compensation Plan (the "Plan")
provides for the grant of performance units ("Performance Units") with respect
to shares of common stock of UGI ("Shares"). The Compensation and Management
Development Committee of the Board of Directors of UGI (the "Committee") has
decided to grant Performance Units to the Participant.

      NOW, THEREFORE, the parties to this Grant Letter, intending to be legally
bound hereby, agree as follows:

1. Grant of Performance Units. Subject to the terms and conditions set forth in
this Grant Letter and in the Plan, the Committee hereby grants to the
Participant __________ Performance Units. The number of Performance Units set
forth above is the target award of Performance Units. The Performance Units are
contingently awarded and will be earned and payable if and to the extent that
the performance goals and other conditions of the Grant Letter are met. The
Performance Units are granted with Dividend Equivalents (as defined in Section
9).

2. Performance Goals.

      (a) The Participant shall earn the right to payment of the Performance
Units if the performance goals described in subsection (b) below are met for the
measurement period, and if the Participant continues to be employed by, or
provide service to, the Company (as defined in Section 9) through December 31,
2006. The measurement period is the period beginning January 1, 2004 and ending
December 31, 2006.

      (b) The target award level of Performance Units and Dividend Equivalents
will be payable if UGI's Total Shareholder Return (TSR) equals the median TSR of
a peer group for the measurement period. The peer group is the group of
companies that comprises the S&P Utilities Index during the measurement period.
The actual amount of the award of Performance Units may be higher or lower than
the target award, or even zero, based on UGI's TSR percentile rank relative to
the companies in the S&P Utilities Index, as follows:

<TABLE>
<CAPTION>
UGI's TSR Rank (Percentile)              Percentage of Target Award Earned
---------------------------              ---------------------------------
<S>                                      <C>
       Highest                                         200%
       90th                                            175%
       75th                                            150%
       60th                                            125%
       50th                                            100%
       40th                                             50%
       less than 40th                                    0%
</TABLE>

The target award percentage earned will be interpolated between each of the
measuring points.

      (c) TSR shall be calculated by UGI using the comparative returns
methodology used by Bloomberg L.P. or its successor at the time of the
calculation. The share price used for determining TSR at the beginning and the
end of the measurement period will be the average price for the 90-day period
preceding the beginning of the measurement period (i.e., the 90-day period
ending on December 31, 2003) and the 90-day period ending on the last day of the
measurement period (i.e., the 90-day period ending on December 31, 2006).

      (d) The target award is the number of Performance Units set forth in
Section 1 above, which is the amount designated for 100% (50th TSR rank)
performance. The Participant can earn up to 200% of the target award if UGI's
TSR rank exceeds the 50th TSR rank, according to the foregoing schedule.

      (e) At the end of the measurement period, the Committee will determine
whether and to what extent the performance goals have been met and the amount to
be paid with respect to the Performance Units. Except as described in Section 3
below, the Participant must be employed by, or providing service to, the Company
on December 31, 2006 in order for the Participant to receive payment with
respect to the Performance Units.

3. Termination of Employment or Service.

      (a) Except as described below, if the Participant's employment or service
with the Company terminates on or before December 31, 2006, the Performance
Units and all Dividend Equivalents credited under this Grant Letter will be
forfeited.

      (b) If the Participant terminates employment or service on account of
Retirement (as defined in Section 9), Disability (as defined in Section 9) or
death, the Participant will earn a pro-rata portion of the Participant's
outstanding Performance Units and Dividend Equivalents, if the performance goals
and the requirements of this Grant Letter are met. The prorated portion will be
determined as the amount that would otherwise be paid after the end of the
measurement period, based on achievement of the performance goals, multiplied by
a fraction, the numerator of which is the number of calendar years during the
measurement period in which the Participant has been employed by, or provided
service to, the Company and the denominator of which is three. For purposes of
the proration calculation, the calendar year in which the Participant's
termination of employment or service on account of Retirement, Disability, or
death occurs will be counted as a full year.

                                       2
<PAGE>

      (c) In the event of termination of employment or service on account of
Retirement, Disability or death, the prorated amount shall be paid after the end
of the measurement period, or at an earlier date determined by the Committee.

4. Coordination with Severance Plan. Notwithstanding anything in this Grant
Letter to the contrary, if the Participant receives severance benefits under a
Severance Plan (as defined in Section 9) and the terms of such benefits require
that severance compensation payable under the Severance Plan be reduced by
benefits payable under this Plan, any amount payable to the Participant with
respect to Performance Units and Dividend Equivalents after the Participant's
termination of employment or service shall be reduced by the amount of severance
compensation paid to the Participant under the Severance Plan, as required by,
and according to the terms of, the Severance Plan.

5. Payment with Respect to Performance Units. If the Committee determines that
the conditions to payment of the Performance Units have been met, the Company
shall pay to the Participant, after the end of the measurement period, (i)
Shares or cash, or a combination of the two, as the Committee determines, equal
to the amount to be paid according to achievement of the performance goals, up
to the target award specified in Section 1 above, and (ii) cash in an amount
equal to the Fair Market Value (as defined in the Plan) of the Shares with
respect to the amount to be paid in excess of the target award.

6. Dividend Equivalents with Respect to Performance Units.

      (a) Dividend Equivalents shall accrue with respect to Performance Units
and shall be payable subject to the same performance goals and terms as the
Performance Units to which they relate. Dividend Equivalents shall be credited
with respect to the target award of Performance Units from the Date of Grant
until the payment date. If the underlying Performance Units are forfeited, all
related Dividend Equivalents shall also be forfeited.

      (b) While the Performance Units are outstanding, the Company will keep
records in a bookkeeping account for the Participant. On each payment date for a
dividend paid by UGI on its common stock, the Company shall credit to the
Participant's account an amount equal to the Dividend Equivalents associated
with the target award of Performance Units held by the Participant on the record
date for the dividend. No interest will be credited to any such account.

      (c) The target amount of Dividend Equivalents (100% of the Dividend
Equivalents credited to the Participant's account) will be earned if UGI's TSR
rank is at the 50th TSR rank for the measurement period. The Participant can
earn up to 200% of the target amount of Dividend Equivalents if UGI's TSR rank
exceeds the 50th TSR rank, according to the schedule in Section 2 above. Except
as described in Section 3(b) above, if the Participant's employment or service
with the Company terminates on or before December 31, 2006, all Dividend
Equivalents will be forfeited.

      (d) Dividend Equivalents will be paid in cash at the same time as the
underlying Performance Units are paid, after the Committee determines that the
conditions to payment have been met. Notwithstanding anything in this Grant
Letter to the contrary, the Participant may not

                                       3
<PAGE>

accrue Dividend Equivalents in excess of $1,000,000 during any calendar year
under all grants under the Plan.

7. Withholding. The Participant shall be required to pay to the Company, or make
other arrangements satisfactory to the Company to provide for the payment of,
