2010 LONG-TERM INCENTIVE PLAN

ON BEHALF OF AMERIGAS PARTNERS, L.P.

PERFORMANCE UNIT GRANT LETTER

This PERFORMANCE UNIT GRANT, dated January 1, 2012 (the “Date of Grant”), is delivered by AmeriGas Propane, Inc. (the “Company”) to              (the “Participant”).

RECITALS

WHEREAS, the AmeriGas Propane, Inc. 2010 Long-Term Incentive Plan on Behalf of AmeriGas Partners, L.P. (the “Plan”) provides for the grant of performance units (“Performance Units”) with respect to common units of AmeriGas Partners, L.P. (“APLP”);

WHEREAS, the Plan has been adopted by the Board of Directors of the Company, and approved by the common unit holders of APLP (“Unitholders”);

WHEREAS, a Performance Unit is a performance unit that represents the value of one common unit of APLP (“Common Unit”);

WHEREAS, the Compensation/Pension Committee of the Board of Directors of the Company (the “Committee”) has decided to grant Performance Units to the Participant on the terms described below;

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 a target award of              Performance Units (the “Target Award”). The Performance Units are contingently awarded and will be earned and payable if and to the extent that the Performance Goals (described below) and other conditions of the Grant Letter are met. The Performance Units are granted with Distribution Equivalents (as defined in the Plan).

2. Performance Goals.

(a) The Participant shall earn the right to payment of the Performance Units if the Performance Goals described below are met for the Performance Period, and if the Participant continues to be employed by the Company through December 31, 2014. The Performance Period is the period beginning January 1, 2012 and ending December 31, 2014. The Total Unit Holder Return (“TUR”) goals and other requirements of this Section 2 are referred to as the “Performance Goals.”

(b) The Target Award level of Performance Units and Distribution Equivalents will be payable if APLP’s TUR equals the median TUR of the comparison group designated by the Committee (the “Peer Group”) for the Performance Period. The Peer Group is the group of master limited partnerships that comprises the Alerian MLP Index as in effect as of the beginning of the Performance Period; provided that if a company is added to the Alerian MLP Index during the Performance Period, that company is not included in the TUR calculation. A company that is included in the Alerian MLP Index at the beginning of the Performance Period will be removed from the TUR calculation only if the company ceases to exist as a publicly traded entity during the Performance Period, consistent with the methodology described in subsection (c) below. The actual amount of the award of Performance Units may be higher or lower than the Target Award, or it may be zero, based on APLP’s TUR percentile rank relative to the companies in the Alerian MLP Index Peer Group, as follows:

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

(c) TUR shall be calculated by the Company using the comparative returns methodology used by Bloomberg L.P. or its successor at the time of the calculation. The price used for determining TUR at the beginning and the end of the Performance Period will be the average price for the 90-day period preceding the beginning of the Performance Period (i.e., the 90-day period ending on December 31, 2011) and the 90-day period ending on the last day of the Performance Period (i.e., the 90-day period ending on December 31, 2014), respectively. The TUR calculation gives effect to all dividends throughout the three-year Performance Period as if they had been reinvested.

(d) The Target Award is the amount designated for 100% (50th TUR rank) performance. The Participant can earn up to 200% of the Target Award if APLP’s TUR percentile rank exceeds the 50th TUR percentile rank, according to the foregoing schedule.

(e) At the end of the Performance 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 the Company or its Affiliates (as defined in the Plan) on December 31, 2014 in order for the Participant to receive payment with respect to the Performance Units.

2

3. Termination of Employment or Service.

(a) Except as described below, if the Participant’s employment with the Company terminates before December 31, 2014, the Performance Units and all Distribution Equivalents credited under this Grant Letter will be forfeited.

(b) If the Participant terminates employment on account of Retirement (as defined below), Disability (as defined in the Plan) or death, the Participant will earn a pro-rata portion of the Participant’s outstanding Performance Units and Distribution 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 Performance Period, based on achievement of the Performance Goals, multiplied by a fraction, the numerator of which is the number of calendar years during the Performance Period in which the Participant has been employed by the Company or its Affiliates 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.

(c) For purposes of this Grant Letter, “Retirement” means the Participant’s separation from employment upon or after attaining (i) age 55 with at least 10 years of service with the Company or its Affiliates, or (ii) age 65 with at least 5 years of service with the Company or its Affiliates.

(d) 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 Performance Period, pursuant to Section 5 below.

(e) The Committee may apply the Plan provisions applicable to transfers of employment and reduction of responsibilities as the Committee deems appropriate.

4. Coordination with Severance Plan.

(a) Notwithstanding anything in this Grant Letter to the contrary, if the Participant receives severance benefits under a Severance Plan (as defined below) and the terms of such benefits require that severance compensation payable under the Severance Plan be reduced by benefits payable under the Plan, any amount payable to the Participant with respect to Performance Units and Distribution Equivalents after the Participant’s termination of employment 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, if permitted by section 409A of the Internal Revenue Code or an exception.

(b) For purposes of this Grant Letter, “Severance Plan” means any severance plan maintained by the Company, UGI Corporation or an Affiliate of the Company or UGI Corporation that is applicable to the Participant.

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, between January 1, 2015 and March 15, 2015, Common Units equal to the number of Performance Units to be paid according to achievement of the Performance Goals, provided that the Company may withhold Common Units to cover required tax withholding in an amount equal to the minimum statutory tax withholding requirement in respect of the Performance Units earned.

6. Distribution Equivalents with Respect to Performance Units.

(a) Distribution 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. Distribution Equivalents shall be credited with respect to the Target Award of Performance Units from the Date of Grant until the payment date. If and to that extent the underlying Performance Units are forfeited, all related Distribution Equivalents shall also be forfeited.

(b) While the Performance Units are outstanding, the Company will keep records of Distribution Equivalents in a bookkeeping account for the Participant. On each payment date for a distribution paid by APLP on its Common Units, the Company shall credit to the Participant’s account an amount equal to the Distribution Equivalents associated with the Target Award of Performance Units held by the Participant on the record date for the distribution. No interest will be credited to any such account.

(c) The target amount of Distribution Equivalents (100% of the Distribution Equivalents credited to the Participant’s account) will be earned if APLP’s TUR rank is at the 50th TUR percentile rank for the Performance Period. The Participant can earn up to 200% of the target amount of Distribution Equivalents if APLP’s TUR rank exceeds the 50th TUR percentile rank, according to the schedule in Section 2 above. Except as described in Section 3(b) above, if the Participant’s employment with the Company terminates before December 31, 2014, all Distribution Equivalents will be forfeited.

(d) Distribution Equivalents will be paid in cash at the same time and on the same terms as the underlying Performance Units are paid, after the Committee determines that the conditions to payment have been met.

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, any federal (including FICA), state, local or other taxes that the Company is required to withhold with respect to the payments under this Grant Letter.

8. Change of Control. If a Change of Control (as defined in the Plan) occurs during the Performance Period, the outstanding Performance Units and Distribution Equivalents shall be paid in cash in an amount equal to the greater of (i) the Target Award amount or (ii) the award amount that would be paid as if the Performance Period ended on the date of the Change of Control, based on the Company’s achievement of the Performance Goals as of the date of the Change of Control, as determined by the Committee. If a former Participant is entitled to receive a prorated award for the Performance Period pursuant to Section 3(b) above, the award will be the prorated portion of the amount described in the preceding sentence. The Performance Units and Distribution Equivalents shall be paid on the closing date of the Change of Control.

The right of the Company to terminate at will the Participant’s employment at any time for any reason is specifically reserved.

Neither the Participant, nor any person entitled to receive payment in the event of the Participant’s death, shall have any of the rights and privileges of a Unitholder with respect to the Common Units related to the Performance Units, unless and until certificates for the Common Units have been issued to the Participant or successor.

12. Assignment and Transfers.
