ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

     Following is a description of compensation arrangements that were approved
by the Board of Directors of Harleysville Group Inc. (the "Company"), upon
recommendation of the Compensation and Personnel Development Committee of the
Company's Board of Directors (the "Committee").

Establishment of Incentive Award Opportunities under the 2006 Senior
Management Incentive Compensation Plan

     On February 21, 2006, the Committee approved incentive award opportunities
for 2006 for the Senior Management Incentive Compensation Plan ("2006 Bonus
Plan"). The 2006 Bonus Plan establishes target bonuses that are a percentage of
base salary paid in 2006 while in an eligible position. The target bonuses are
50% and 35% of base salary for the CEO and other executive officers,
respectively.

     Forty percent of the target award is based on the Company's combined ratio,
30 percent is based on the Company's operating return on equity, and 30 percent
is based on performance of individual objectives.

     The 2006 Bonus Plan provides for actual bonuses ranging from 0% to 200% of
the target bonuses depending upon the extent to which corporate and individual
objectives are attained. For bonuses to be paid, the Company must achieve a
minimum operating return on equity. Payment of the bonuses, if any, is expected
to be made in March 2007.

Long Term Incentive Award Opportunities

     Also on February 21, 2006, the Committee decided that it would not
establish target awards under the Company's Long Term Incentive Compensation
Plan for the three-year performance period commencing in 2006. The Committee
intends to provide long-term incentive compensation to executives in the form of
stock options and restricted stock under an Amended and Restated Equity
Incentive Plan that will be presented for shareholder approval at the Company's
Annual Meeting on April 26, 2006. The Committee intends to grant stock options
and restricted stock to executives following the Company's 2006 Annual Meeting.

Revisions to Non-Qualified Deferred Compensation Plan

     On February 22, 2006, upon recommendation of the Committee, the Board
approved amendments to the Company's Non-Qualified Deferred Compensation Plan
(the "Plan"). The Plan was amended to change the provisions regarding payment of
benefits and the definition of retirement and some minor changes to the
definition of unforeseeable emergency, to comply with the requirements of
Internal Revenue Code section 409A.


Change in Control Agreements

     On February 21, 2006, the Committee approved Change in Control agreements
between the Company and each of the following Section 16 reporting officers:
Allen Becker, Senior Vice President and Chief Actuary, Deborah A. Neuscheler,
Senior Vice President - Performance Excellence and Kevin Toth, Senior Vice
President - Claims. The Change in Control Agreements have the same terms that
are described in Item 1.01 of the Company's Report on Form 8-K originally filed
with the Securities and Exchange Commission on January 6, 2005, and the form of
which is attached thereto as Exhibit 10.1 and incorporated herein by reference.
