Sono-Tek will continue your employment as Controller, reporting to the CEO of the Company. 2. Your compensation will consist of a base salary and a bonus plan based on the overall financial performance of the Company.

You currently have no options to purchase shares of common stock of . 1 Sono-Tek The Company has been advised by legal counsel that the 1983 Incentive Stock Option plan for key employees is flawed. In addition, the 1,000,000 shares reserved for issuance under the Plan is out of line with generally accepted levels.
