Plan Description In August 1997, the stockholders adopted, effective July 1, 1997, the Datron Systems Incorporated Employee Stock Purchase Plan (the "Stock Purchase Plan") under Section 423 of the Internal Revenue Code. The Stock Purchase Plan is intended to provide eligible employees with the opportunity to acquire an equity interest in Datron Systems Incorporated (the "Company") through the acquisition of purchase rights. Employees are eligible to participate in the plan if they have been employed a minimum of six months and work at least 20 hours per week. Eligible employees may use funds from accumulated payroll deductions to purchase shares of Company common stock at the end of six-month offering periods. They may contribute up to 10% of gross earnings toward such purchases, not to exceed $12,500 per offering period, and may purchase a maximum of 1,000 shares per offering period. The purchase price for the shares is 85% of the lesser of the fair market value of the common stock at the beginning of the offering period or at the end of the offering period. Shares purchased must be held for a minimum of three months before they can be sold. At the end of the first offering period on December 31, 1997, the Company issued 6,126 shares of common stock to employees at a purchase price of $7.33 per share.
