* 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

* 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

* breached any provision of the Agreement; or (B) Realsee is required to do so by
* law; or (C) Realsee decides to no longer provide the SDK or certain parts of the
* SDK to users in the country in which You are resident or from which You use the
* service, or the provision of the SDK or certain SDK services to You by Realsee
* is, in Realsee's sole discretion, no longer legally or commercially viable.
* 5.3 When the Agreement comes to an end, all of the legal rights, obligations and
* liabilities that You and Realsee have benefited from, been subject to (or which
* have accrued over time whilst the Agreement has been in force) or which are
* expressed to continue indefinitely, shall be unaffected by this cessation, and

* rights, obligations and liabilities indefinitely.
* 6. DISCLAIMER OF WARRANTY.
* YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT, TO THE EXTENT PERMITTED BY APPLICABLE
* LAW, USE OF THE SDK (OR ANY PART THEREOF) IS AT YOUR SOLE RISK AND THAT THE
* ENTIRE RISK AS TO SATISFACTORY QUALITY, PERFORMANCE, ACCURACY, AND EFFORT IS

* MAKES NO REPRESENTATION WITH RESPECT TO THE ADEQUACY OF ANY ITEMS IN THE SDK,
* WHETHER OR NOT USED BY YOU IN THE DEVELOPMENT OF INTEGRATED PRODUCT, FOR ANY
* PARTICULAR PURPOSE OR WITH RESPECT TO THEIR ADEQUACY TO PRODUCE ANY PARTICULAR
* RESULT. REALSEE AND ITS LICENSORS SHALL NOT BE LIABLE FOR LOSS OR DAMAGE ARISING
* OUT OF THIS AGREEMENT OR FROM THE DISTRIBUTION OR USE OF INTEGRATED PRODUCT
* CONTAINING PORTIONS OF THE SDK. REALSEE AND ITS LICENSORS DISCLAIM ALL
* WARRANTIES, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED

* 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
* IF THE ABOVE STATED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. THE LIMITATIONS

* applicable open source or third party agreement, the open source or third party
* agreement will control solely with respect to the open source software or third
* party software. Moreover, You shall not subject any items (including not limited
* to source code, object code, and any software) included in the SDK to any open
* source license.

* and products in the future that have or may have design and/or functionality
* similar to Integrated Product that You may develop based on Your license herein.
* 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
* (or any part thereof) except as authorized by United States law and the laws of

* particular, but without limitation, the SDK may not be exported or re-exported
* (i) into any U.S. embargoed countries or (ii) to anyone on the U.S. Treasury
* Department's list of Specially Designated Nationals or the U.S. Department of
* Commerce Denied Person's List or Entity List. By using the SDK (or any part
* thereof), You represent and warrant that You are not located in any such country
* or on any such list.
* 11.2 Governing Law. This Agreement and the rights of the parties hereunder shall
* be governed by and construed in accordance with the laws of People’s Republic of
* China (for purpose of this Agreement, excluding Hong Kong, Taiwan, and Macau),
* without reference to its conflict of laws principles. Any dispute, controversy
* or claim arising from or in connection with this Agreement, or the breach,
* termination or invalidity thereof, shall be submitted to China International
* Economic and Trade Arbitration Commission (“CIETAC”) for arbitration in Beijing
* which shall be conducted in accordance with the CIETAC's arbitration rules in
* effect at the time of applying for arbitration. The arbitral award is final and
* binding upon both parties.
* 11.3 Severability. If any provision of this Agreement is held by a court of

* without notice to You, to make revisions to this Agreement in our sole and
* absolute discretion. The most current version of this Agreement will supersede
* all previous versions and shall be made available on the website where the SDK
* is made available, or by such other means as Realsee may determine in its
* discretion. Any modified versions of this Agreement hereto shall take effect
* from the time that it is made available. You shall be responsible for regularly
* checking for notice of any such modifications. You agree that Your continued use
* of the SDK constitutes Your agreement to the modified Agreement.
* 11.5 Relationship of the Parties. This Agreement will not be construed as
* creating an agency, partnership, joint venture, fiduciary duty, or any other
* form of legal association between You and Realsee, and You will not represent to
* the contrary, whether expressly, by implication, appearance, or otherwise.
* 11.6 Entire Agreement; Governing Language. This Agreement constitutes the entire
* agreement between You and Realsee with respect to the use of the SDK licensed
