grant of the Options, but intend that, except to the extent set forth herein,
all of the terms and conditions of the Options shall be as contained in the
Plan.

covenants and agreements contained herein and in the Plan, the parties hereto
hereby agree as follows:

         1. THE OPTIONS. Subject to the terms and conditions set forth herein
and in the Plan, the Company's Incentive Compensation Committee has granted the
Participant Options to purchase 100,000 shares of the Common Stock (the
"Shares") at an exercise price of $2.8125 per Share (the last reported sale
price of the Common Stock on August 2, 1999) exercisable immediately for a
period of five (5) years from the date of this Agreement.

         2. EXERCISE. The Options may be exercised by the Participant only at
the times and in the manner set forth herein and in the Plan.

forth herein, all of the terms and conditions of the Options are contained in
the Plan and there are no other agreements, written or oral, with respect
thereto. Neither this Agreement nor the existence of the Options shall be
construed as giving Participant any right to be retained in the employ of the
Company or any of its affiliates.

         7. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Indiana.
