qualified under Section&#160;401(a)&#160;of the IRC, and exempt from taxation. Although the Plan has been amended since receiving the determination letter, the Plan administrator believes that the Plan is designed, and is currently being operated, in compliance with the applicable requirements of the IRC and, therefore, believes that the Plan is qualified, and related trust is tax exempt. Once qualified, the Plan is required to operate in conformity with the IRC to maintain its qualification.
