CONFIDENTIAL

AGREEMENT AND RELEASE





This Agreement and Release (Agreement) is dated _____________ (Today).  It is between Catherine B. Strauss (you) and Harleysville Group Inc., a Delaware corporation and Harleysville Mutual Insurance Company, a Pennsylvania corporation (collectively the Company).





You and the Company intend to be legally bound by this Agreement, and are entering into it in reliance on the promises made to each other in this Agreement.  Effective January 2, 2007, you are taking early retirement from the Company and, thus, your employment relationship with the Company will end.  In light of the many years of service you have provided as a senior executive to the Company, the Company will pay you certain benefits described in this Agreement.  In turn, as set forth in this Agreement, you are releasing legal claims against the Company.



1.

Your Separation Date.  Your employment will end on January 2, 2007 ("Separation Date").



2.

Officer Status.  You resign as and are no longer an officer, plan administrator, and/or director of the Company, or any affiliate or a member of any committee after your Separation Date.



3.

Pay and Benefits until Separation Date.

a.

From Today until your Separation Date, the Company will pay you your current regular salary and you may continue to participate in the Companys employee benefits programs.



b.

Within 30 days after your Separation Date, the Company will pay you (less applicable withholding in a lump sum) for 22 days of accrued but unused vacation time, constituting all vacation pay due to you up through your Separation Date.

---

c.

If you die before the Separation Date, the date you die will automatically become your new Separation Date, and neither you nor your estate will receive the payments set forth below in Paragraph 5.a.



4.

Career Transition Services.  The Company will pay for the cost of six (6) months of career transition services, commencing on the date this Agreement is signed by you.   The Companys payment for such career transition services will be limited to $9,500.00 for that six-month period.  In the event that you have not found new employment upon the expiration of that six-month period, the Company will extend payment for your career transition services, on a monthly basis, for an additional period of six months or until you find new employment, whichever occurs first.



5.

Your Benefits After Separation Date.  Once this Agreement becomes effective in accordance with Paragraph 14 below, you will receive the following payments and benefits after the Separation Date:

a.

The Company will make payments to you from the day after your Separation Date at your bi-weekly salary rate in effect on your Separation Date until July 2, 2007.  Payments will be made in bi-weekly installments on regular paydays in accordance with normal Company payroll practices and subject to applicable federal, state, and local withholding.  If by July 2, 2007 or at any point between July 2, 2007 and January 2, 2008, you obtain employment as a senior level executive with a for-profit company with annual revenues in excess of $100,000,000, then the Company will stop making payments to you as of the date your new employment commences.  If by July 2, 2007, you have not obtained new employment, then the Company will continue making payments to you at the same rate for up to an additional six months, until January 2, 2008.  However, if by July 2, 2007 or at any point between July 2, 2007 and January 2, 2008, you obtain new employment teaching, working for a non-profit company, or working for a for-profit company with annual revenues of $100,000,000 or less, or are self-employed, then the Company will continue making payments to you, but the Company will subtract from the payment the compensation you receive from the new employment after July 2, 2007, thereby offsetting your new compensation from the Companys payment, for up to an additional six months, until January 2, 2008. You have a duty to inform Robert A. Kauffman, in writing, at 355 Maple Avenue, Harleysville, PA 19438, within 5 calendar days of obtaining



2

employment.  The period you receive these bi-weekly payments is your Payment Period.



b.

If you die before the end of the Payment Period, any and all payments due to be paid to you in the future under this Agreement as of the date of your death will be paid in a lump sum within ninety (90) days after your death to your surviving spouse.  If you have no surviving spouse, the payment will be made to your estate.



c.

Beginning on January 3, 2007, you may elect to continue your medical and dental coverage under COBRA.  If you do elect to do so, the Company will pay the full cost of continuing your medical and dental coverage as of Today under COBRA throughout the earlier of the end of the Payment Period and the date on which you obtain such benefits through other employment.



d.

You may convert your group life insurance coverage to individual coverage in accordance with the terms of the Companys group life insurance plan.  The Company will provide you with sufficient information to enable you to convert your group life insurance coverage within thirty-one (31) days after your Separation Date.



e.

You may be entitled to benefits under the Company's Pension Plan, Supplemental Executive Retirement Plan, Retirement Savings Plus Plan, the Non-Qualified Deferred Compensation Plan, the Equity Incentive Plan, the Long Term Incentive Plan, or the Senior Management Incentive Plan.  Any and all benefits due under these plans shall be paid to you in accordance with the terms of those plans.  Without limiting the foregoing, the Company agrees:



(1)

Your payment under the Senior Management Incentive Plan (SMIP) for 2006 will consist of: (i) full payment due under the formulaic component (Part A) of the SMIP; and (ii) 50% of the payment due under the discretionary component (Part B) of the SMIP at target.

---

(2)

If there is a payout under the 2004-2006 Long-Term Incentive Plan, you will receive the full amount of payment to which you are entitled, based on 36 months of employment.



(3)

If there is a payout under the 2005-2007 Long-Term Incentive Plan, you will receive a pro rata portion of the payment, based on 24 months of employment, rather than 36 months of employment.



(4)

You will receive three-fifths of the restricted stock award granted to you on April 26, 2006.  The total number of restricted stocks granted to you on April 26, 2006 totaled 1520; therefore, you will receive 912 shares of the restricted stock granted to you on April 26, 2006 upon your Separation Date.  The remaining two-fifths of the restricted stock award granted on April 26, 2006, totaling 608 shares, will be forfeited.



f.

The Company will pay you no other money or supply any other benefits except as described in this Agreement.  You shall not be eligible for, or be entitled to receive awards or compensation under, any existing incentive, retirement, pension, or other employee-related plan of the Company for calendar year 2007, notwithstanding the Separation Date of January 2, 2007.



g.

The Company will issue a statement to the employees in the form attached hereto as Exhibit A.  In response to any reference requests on your behalf, the Company will provide information consistent with Exhibit A, as well as your job title and dates of employment, and will state that early retirement was the reason for your separation from the Company.  You and the Company will direct all requests for references for you to the Companys head of Human Resources.  The Company and its officers (i) shall not make any statements about you that are untrue or disparaging; and (ii) shall not take any actions intended to damage your reputation, cause you any embarrassment or humiliation or otherwise cause or contribute to you being held in disrepute by the general public or the Companys employees, agents, clients, or customers.  The provisions of this Paragraph shall survive termination of the Payment Period.
