* Information solely in accordance with the license granted hereunder. In any
* event, You and Your Affiliates shall treat Confidential Information as strictly
* confidential and shall use the same care to prevent disclosure of such

* 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

* Nothing in this Agreement shall impair, limit or curtail Realsee's right to
* continue with its development, maintenance and/or distribution of Realsee's
* technology or products.
* 11. GENERAL.
* 11.1 Export Control. You may not use or otherwise export or re-export the SDK
