TABLE OF CONTENTS

HARLEYSVILLE GROUP INC.
NON-QUALIFIED EXCESS CONTRIBUTION AND MATCH PROGRAM

AMENDED AND RESTATED AS OF JANUARY 1, 2008

ARTICLE I -  PURPOSE

This Non-Qualified Excess Contribution and Match Program (the “Program”) permits certain employees of Harleysville Group Inc. (the “Company”), through an unfunded non-qualified deferred compensation plan, to receive the full Company contribution and match that otherwise would have been available under the Harleysville Retirement Savings Plus Plan (the “Retirement Plan”) but for the limitations, established by the Internal Revenue Code (the “Code”), on contributions, deferrals, and matches. The Program has the further objective of attracting and retaining senior management personnel of superior caliber and of affording them a means of participating in the overall success of the Company.  For purposes of the Employee Retirement Income Security Act of 1974, as amended, this Program is intended to be unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees. This amended and restated Program document is intended to satisfy the applicable requirements of Section 409A of the Code.

ARTICLE II -  DEFINITIONS

For the purposes of this Program, the definitions found in the Retirement Plan shall govern except as otherwise provided herein.

The Harleysville Retirement Savings Plan Administrative Committee (the “Committee”) shall have responsibility for the implementation and administration of this Program. The Committee shall interpret the Program and shall establish rules and regulations governing the Program’s administration. The Committee shall have discretion to determine, without limitation, which employees are eligible to participate in this Program, and the amounts payable to Participants under this Program.  Any decision made or action taken by the Committee, arising
