Executive Incentive Compensation Plan (collectively, the “Plans”);

WHEREAS, Executive’s participation in the Plans requires execution of this Agreement in order to be eligible to receive benefits under such Program; and

WHEREAS, Executive previously entered into an Employment Agreement with DPL and DP&L (collectively, the “Company”), dated September 17, 2003, and a Change of Control Letter Agreement with the Company, dated July 1, 2004 (the “Prior Agreements”);

NOW THEREFORE, in consideration of the promises and agreements contained herein and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, and intending to be legally bound, Executive agrees as follows:

1.             Effective Date.  This Agreement is effective on the date hereof and will continue in effect as provided herein.

2.             Participation in the Plans.  DPL confirms that Executive (a) has been designated by the Committee and the Board to participate in each of the Plans pursuant to the terms thereof, contingent on her execution of this Agreement and, with respect to the EPIP, its approval by the shareholders of the Company at their annual meeting on April 26, 2006, and (b) is eligible to receive additional benefits as such are provided to other similarly situated employees of the Company from time to time.

3.             Termination of Prior Agreements.  Executive, for herself and her dependents, successors, assigns, heirs, executors and administrators (and her and their legal representatives of every kind), and the Company hereby agree that, upon execution of this Agreement, the Prior Agreements shall terminate and have no further force and effect.

4.             Remaining Rights.  Notwithstanding the terms of Section 3 of this Agreement, Executive and the Company hereby agree that nothing in this Agreement negates or diminishes Executive’s rights under any agreement other than the Prior Agreements, including, the rights (a) with respect to any stock incentive units granted under DP&L’s Management Stock Incentive Plan, subject to the terms and conditions contained in the Non-Competition Agreement between the Company and Executive, dated October 3, 1996, a copy of which is attached hereto as Exhibit A, and as further described in the Letter Agreement between the Company and Executive, dated April 27, 2001, a copy of which is attached hereto as Exhibit B, and (b) to purchase from DPL, to the extent not yet purchased, up to a total of 50,000 common shares of DPL at an exercise price of $29 5/8 per share pursuant to the terms of Executive’s Management Stock Option Agreement, dated January 1, 2001, a copy of which is attached hereto as Exhibit C.

5.             Perquisite Allowance.  By executing this Agreement, Executive shall be entitled to receive a perquisite allowance in the amount of $20,000 per year (the “Perquisite Allowance”), for each year that (a) Executive remains designated by the Committee as eligible to receive the Perquisite Allowance and (b) DPL continues to make the Perquisite Allowance available to executive-level employees of the Company.  Executive has been designated by the Committee as eligible to receive the Perquisite Allowance for 2006.  The Perquisite Allowance for 2006 shall be paid as soon as practicable after the Effective Date.  The Perquisite Allowance for years after 2006 shall be paid to Executive as soon as practicable after the Committee designates Executive as eligible to receive the Perquisite Allowance for that year.  The Perquisite Allowance will not be deemed “compensation,” as that term is defined under any of the Plans, nor under any other plan, practice, program or policy of the Company or any of its affiliates, as in effect from time to time.

6.             Non-Solicitation.  As a condition to her eligibility to participate in the Program, Executive hereby agrees that during her employment and for a period of two years following her termination of employment with the Company, Executive will not (a) solicit for employment with herself or any firm or entity with which she is associated, any employee of DPL, its subsidiaries or affiliates, or otherwise disrupt, impair, damage or interfere with DPL’s, its subsidiaries’ or affiliates’ relationships with their employees or (b) solicit for Executive’s own behalf or on behalf of any other person(s), any retail customer of DPL, its subsidiaries or affiliates, that has purchased products or services from the DPL, its subsidiaries or affiliates, at any time (i) with respect to solicitation during employment, during the Executive’s employment or (ii) with respect to solicitation after termination of employment, in the twelve months preceding the date on which
