THE COMMITTEE

Sec. 7.01 Appointment and Tenure of Administrative Committee Members.

Any Administrative Committee member may resign by delivering his or her written resignation to the Compensation/Pension Committee. Vacancies arising by the death, resignation or removal of an Administrative Committee member may be filled by the Compensation/Pension Committee.

Sec. 7.02 Meetings; Majority Rule. Any and all acts of the Administrative Committee taken at a meeting shall be by a majority of all members of the Administrative Committee. The Administrative Committee may act by vote taken in a meeting (at which a majority of members shall constitute a quorum). The Administrative Committee may also act by unanimous consent in writing without the formality of convening a meeting.

Sec. 7.03 Delegation. The Administrative Committee may, by majority decision, delegate to each or any one of its members, authority to sign any documents on its behalf, or to perform ministerial acts, but no person to whom such authority is delegated shall perform any act involving the exercise of any discretion without first obtaining the concurrence of a majority of the members of the Administrative Committee, even though such person alone may sign any document required by third parties. The Administrative Committee shall elect one of its members to serve as Chairperson. The Chairperson shall preside at all meetings of the Administrative Committee or shall delegate such responsibility to another Administrative Committee member. The Administrative Committee shall elect one person to serve as Secretary to the Administrative Committee. All third parties may rely on any communication signed by the Secretary, acting as such, as an official communication from the Administrative Committee.

Sec. 7.04 Authority and Responsibility of the Administrative Committee. The Administrative Committee shall have only such authority and responsibilities as are delegated to it by the Compensation/Pension Committee or specifically under this AGP SERP. The Administrative Committee shall have full power and express discretionary authority to administer and interpret the AGP SERP, to make factual determinations and to adopt or amend such rules and regulations for implementing the AGP SERP and for the conduct of its business as it deems necessary or advisable, in its sole discretion.

(g) promulgation of procedures for determination of claims for benefits.

Sec. 7.05 Compensation of Administrative Committee Members. The members of the Administrative Committee shall serve without compensation for their services as such, but all expenses of the Administrative Committee shall be paid or reimbursed by AGP.

Sec. 7.06 Committee Discretion. Any discretion, actions or interpretations to be made under the AGP SERP by the Administrative Committee or by the Compensation/Pension Committee on behalf of AGP shall be made in its sole discretion, not acting in a fiduciary capacity, need not be uniformly applied to similarly situated individuals, and shall be final, binding and conclusive upon the parties. All benefits under the AGP SERP shall be provided conditional upon the Participant’s acknowledgement, in writing or by acceptance of the benefits, that all decisions and determinations of the Administrative Committee shall be final and binding on the Participant, his or her beneficiaries and any other person having or claiming an interest under the AGP SERP.

Sec. 7.07 Indemnification of the Committees. Each member of the Administrative Committee and each member of the Compensation/Pension Committee shall be indemnified by AGP against costs, expenses and liabilities (other than amounts paid in settlement to which AGP does not consent) reasonably incurred by the member in connection with any action to which the member may be a party by reason of the member’s service on the applicable Committee, except in relation to matters as to which the member shall be adjudged in such action to be personally guilty of gross negligence or willful misconduct in the performance of the member’s duties. The foregoing right to indemnification shall be in addition to such other rights as the Administrative Committee member or the Compensation/Pension Committee member may enjoy as a matter of law or by reason of insurance coverage of any kind, but shall not extend to costs, expenses and/or liabilities otherwise covered by insurance or that would be so covered by any insurance then in force if such insurance contained a waiver of subrogation. Rights granted hereunder shall be in addition to and not in lieu of any rights to indemnification to which the Administrative Committee member or the Compensation/Pension Committee member may be entitled pursuant to the by-laws of AGP. Service on the Administrative Committee or the Compensation/Pension Committee shall be deemed in partial fulfillment of the applicable Committee member’s function as an employee, officer, or director of AGP, if the Committee member also serves in that capacity.

ARTICLE VIII

AMENDMENT AND TERMINATION

Sec. 8.01 Amendment. The provisions of the AGP SERP may be amended at any time and from time to time by a resolution of the Board; provided, however, that no such amendment shall serve to reduce the benefit that has accrued on behalf of a Participant as of the effective date of the amendment, and, provided further, however, that the Compensation/Pension Committee may make such amendments as are necessary to keep the AGP SERP in compliance with applicable law and minor amendments which do not materially affect the rights of the Participants or significantly increase the cost to AGP, AmeriGas Partners, L.P. or AmeriGas Propane, L.P.

Sec. 8.02 AGP SERP Termination. While it is AGP’s intention to continue the AGP SERP indefinitely in operation, the right is, nevertheless, reserved to terminate the AGP SERP in whole or in part at any time for any reason without either the consent of or prior notice to any Participant. No such termination shall reduce the benefit that has accrued on behalf of a Participant as of the effective date of the termination, but AGP may immediately distribute all accrued benefits upon termination of the AGP SERP in accordance with section 409A of the Code.

Sec. 10.03 Severability of Provisions. If any provision of the AGP SERP shall be held invalid or unenforceable, such validity or unenforceability shall not affect any other provisions hereof, and the AGP SERP shall be construed and enforced as if such provision had not been included.
