Addendum to Retention and Severance Agreement between Adaptive Broadband Corporation and George Arena

Summary

This addendum, effective July 5, 2000, modifies the retention and severance agreement between Adaptive Broadband Corporation and employee George Arena. It allows Mr. Arena to serve as a director on the board of Moseley Associates without affecting his severance pay, unless his compensation from that role exceeds $20,000 in a 12-month period, in which case the excess will reduce his severance dollar-for-dollar. Serving as a director elsewhere does not impact his severance. All other terms of the original agreement remain unchanged.
