*The employment agreement for Mr. Tsui is not available in electronic format. Below is a description such agreement:
In September 1988, we entered into an employment letter with Mr. Tsui pursuant to which Mr. Tsui serves as Chief Executive Officer. In addition to providing for an annual base salary and bonus arrangements, the letter provides that in the event of a change in control of Lattice, any unvested options to purchase our common stock held by Mr. Tsui shall become fully vested. Additionally, in the event Mr. Tsui is involuntarily terminated, other than for cause, we must continue to pay his salary for up to six months, or until Mr. Tsui begins employment elsewhere, whichever occurs sooner, and options vesting during that period are exercisable.
