This PHANTOM UNIT GRANT, dated January 9, 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 Phantom Units (“Phantom 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 (the “Board”), and approved by common unit holders of APLP (“Unitholders”);

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

WHEREAS, the Board has decided to grant Phantom 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 Phantom Units.

(a) Subject to the terms and conditions set forth in this Grant Letter, the Board hereby awards the Participant an award of 500 Phantom Units (as defined in Section 4). The Phantom Units are granted with Distribution Equivalents (as defined in Section 4).

(b) The Company shall keep records in an Account (as defined in Section 4) to reflect the number of Phantom Units and Distribution Equivalents credited to the Participant. Fractional Phantom Units shall accumulate in the Participant’s Account and shall be added to other fractional Phantom Units to create whole Phantom Units.

2. Distribution Equivalents with Respect to Phantom Units.

(a) Crediting of Distribution Equivalents. From the Date of Grant until the Participant’s Account has been fully distributed, 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 Equivalent associated with the Phantom Units credited to the Participant on the record date for the distribution.

(b) Conversion to Phantom Units. On the last day of each Plan Year (as defined in Section 4), the amount of the Distribution Equivalents credited to the Participant’s Account during that Plan Year shall be converted to a number of Phantom Units, based on the Unit Value (as defined in Section 4) on the last day of the Plan Year. In the event of a Change of Control (as defined in the Plan) or in the event the Participant dies or Separates from Service (as defined in Section 4) prior to the last day of the Plan Year, as soon as practicable following such event, and in no event later than the date on which Phantom Units are redeemed in accordance with Section 3, the Company shall convert the amount of Distribution Equivalents previously credited to the Participant’s Account during the Plan Year to a number of Phantom Units based on the Unit Value on the date of such Change of Control, death or Separation from Service.

3. Events Requiring Redemption of Phantom Units.

(a) Redemption. The Company shall redeem Phantom Units credited to the Participant’s Account at the times and in the manner prescribed by this Section 3. When Phantom Units are to be redeemed, the Company will determine the Unit Value of the Phantom Units credited to the Participant’s Account as of the date of the Participant’s Separation from Service or death. Except as described in subsection (c) below, an amount equal to 65% of the aggregate Unit Value will be paid in the form of whole Common Units (with fractional Common Units paid in cash), and the remaining 35% of the aggregate Unit Value will be paid in cash.

(b) Separation from Service or Death. In the event the Participant Separates from Service or dies, the Company shall redeem all the Phantom Units then credited to the Participant’s Account as of the date of the Participant’s Separation from Service or death. In the event of a Separation from Service, the redemption amount shall be paid within 30 business days after the date of the Participant’s Separation from Service. In the event of death, the redemption amount shall be paid to the Participant’s estate within 60 business days after the Participant’s death.

(c) Change of Control. In the event of a Change of Control, the Company shall redeem all the Phantom Units then credited to the Participant’s Account. The redemption amount shall be paid in cash on the closing date of the Change of Control (except as described below). The amount paid shall equal the product of the number of Phantom Units being redeemed multiplied by the Unit Value at the date of the Change of Control. However, in the event that the transaction constituting a Change of Control is not a change in control event under section 409A of the Code (as defined in Section 4), the Participant’s Phantom Units shall be redeemed and paid in cash upon Separation from Service or death on the applicable date described in subsection (b) above (based on the aggregate Unit Value on the date of Separation from Service or death as determined by the Board), instead of upon the Change of Control pursuant to this subsection (c). If payment is delayed after the Change of Control, pursuant to the preceding sentence, the Board may provide for the Phantom Units to be valued as of the date of the Change of Control and interest to be credited on the amount so determined at a market rate for the period between the Change of Control date and the payment date.

2

(d) Deferral Elections. Notwithstanding the foregoing, pursuant to the Deferral Plan, the Participant may make a one-time, irrevocable election to elect to have all of the Participant’s Phantom Units credited to the Participant’s account under the Deferral Plan on the date of the Participant’s Separation from Service, in lieu of the redemption and payments described in subsection (b) above. If the Participant makes a deferral election, the Participant’s Phantom Units will be credited to the Participant’s account under the Deferral Plan at Separation from Service and the amount credited to the Deferral Plan shall be distributed in accordance with the provisions of the Deferral Plan. If the Participant makes a deferral election under the Deferral Plan and a Change of Control occurs: (i) subsection (c) above shall apply if the Change of Control occurs before the Participant’s Separation from Service and (ii) the terms of the Deferral Plan shall apply if the Change of Control occurs after or simultaneously with the Participant’s Separation from Service. An election under the Deferral Plan shall be made in writing, on a form and at a time prescribed by the committee that administers the Deferral Plan and shall be irrevocable upon submission to the Corporate Secretary. A deferral election shall be made in accordance with section 409A of the Code.
