Exhibit 10.17 [AIRSPAN LOGO] 15 February 2001 Private and Confidential David Brant Airspan Communications Ltd Dear David Congratulations on your appointment to the Executive Level Team. I would like to confirm that the board of directors has ratified a grant of 75,000 share options for you at the close of market price on February 7th, 2001, under the normal terms of the 1998 Airspan Stock Option Plan. Human Resources will be forwarding documentation related to this grant shortly. Furthermore, as a member of the Executive Level Team, you are entitled to 9 months of severance in the unlikely event that your employment is terminated without cause. I would also like to confirm that an increase to your base salary of 6700 Sterling has been approved to be incorporated in the April 1st pay adjustment. Your handling of the Alcatel issue is deserving of specific recognition and exceeds even the high standards which you have established for the department. I am delighted to inform you that Airspan is paying you a bonus of 6000 Sterling, grossed up for taxes, in recognition of your work in bringing the Alcatel bond to closure. This bonus will be paid immediately and hopefully can offset some of the cost of a well deserved vacation.
