Amended and Restated Stock Incentive Plan; (ii) Verint Systems Inc.

Accordingly, the Company hereby terminates the effectiveness of the Registration Statements and, pursuant to the undertakings contained in the Registration Statements to remove from registration by means of a post-effective amendment any shares of Common Stock that had been registered for issuance but remain unsold at the termination of the offering, the Company hereby removes from registration any remaining Common Stock that was registered for issuance pursuant to the Registration Statements and that remain unsold as of the date hereof. The Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such Common Stock.
