Section 1 - Business and Operations

Item 1.02 - Termination of a material definitive agreement.

On May 15, 2006, the Board of Directors of the Company terminated the 2003
Employee Stock Purchase Plan ("Plan"), effective immediately. The Plan
originally was to continue in effect until all shares of the Company's common
stock reserved for issuance under the Plan had been purchased unless terminated
prior thereto by the Board of Directors of the Company. The Plan allows the
Board of Directors to terminate the Plan at anytime without prior notice to the
participants and without liability to the participants. The Plan allowed
eligible employees to participate in the Plan by purchasing up to an aggregate
of 1,500,000 shares of the Company's common stock through payroll deductions.
The Plan authorized the purchase of shares at an exercise price of 85% of the
market price of common stock on the offering date or the exercise date,
whichever is lower. A total of 96,380 shares had been purchased under the Plan
prior to the Plan's termination. The Plan provides that upon termination, the
balance, if any, then standing to the credit of each participant in the
participant stock purchase account shall be refunded to the participant.
