Upon termination without cause, the Company is required to pay the amount of severance due under the employment agreement, if any. The Company also requires its vice presidents to agree in their employment letters and their employment agreement, if applicable, not to compete with the Company during the term of their employment, and for a certain period after their employment ends.

The Company is currently not a party to any litigation which, if resolved adversely against the Company, would, in the opinion of management, after consultation with legal counsel, have a material adverse effect on the Company’s business, financial position or results of operations.
