Websense, the provider of security software products mainly for larger companies, agreed to be acquired May 20.

Completion of the tender offer is subject to conditions, including the satisfaction of a minimum tender condition, the expiration or termination of waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the receipt of proceeds under executed bank commitments, the companies said.

The tender offer and withdrawal rights are scheduled to expire June 25 unless extended or terminated earlier in accordance with the terms of the agreement, the companies said.
