* Information solely in accordance with the license granted hereunder. In any
* event, You and Your Affiliates shall treat Confidential Information as strictly

* shall ensure that Your Affiliates comply with the provisions of this Section 3,
* and You shall be liable for any breach of this Section 3 resulting from the act

* copyrights, trade secrets, trademarks or any other rights in respect to the
* items in the SDK.
* 5. TERM AND TERMINATION.
* 5.1 This Agreement is effective until terminated. Realsee has the right to

* OR OTHERWISE) AND EVEN IF REALSEE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
* DAMAGES. IN NO EVENT WILL REALSEE’S TOTAL LIABILITY TO YOU FOR ALL DAMAGES
* EXCEED ONE HUNDRED DOLLARS ($100.00). THE FOREGOING LIMITATIONS WILL APPLY EVEN
