84 publicly perform, sublicense, copy, create derivative works of,
85 and make modifications to LTX-2, for any purpose, subject to the
86 restrictions set forth in Attachment A; provided however, that
87 Entities with annual revenues of at least $10,000,000 (the
88 "Commercial Entities") are required to obtain a paid commercial
89 use license in order to use LTX-2 and Derivatives of LTX-2,
90 subject to the terms and provisions of a different license (the
91 "Commercial Use Agreement"), as will be provided by the Licensor.
92 Commercial Entities interested in such a commercial license are

95 Entities not in accordance with this Agreement and/or the Commercial
96 Use Agreement is strictly prohibited and shall be deemed a material
97 breach of this Agreement.
98 Such material breach will be subject, in addition to any license
99 fees owed to Licensor for the period such Commercial Entity used
100 LTX-2 (as will be determined by Licensor), to liquidated damages,

263 prior to termination, including payment obligations under
264 Section 2. In addition, if You commence a lawsuit or other
265 proceedings (including a cross-claim or counterclaim in a lawsuit)
266 against Licensor or any person or entity alleging that LTX-2 or
267 any Output, or any portion of any of the foregoing, infringe any
268 intellectual property or other right owned or licensable by you,
269 then all licenses granted to you under this Agreement shall
270 terminate as of the date such lawsuit or other proceeding is filed.
271
272 14. Disputes and Arbitration. All disputes arising in connection with
273 this Agreement shall be finally settled by arbitration under the

276 the ICC Rules. The seat of arbitration shall be New York, NY, USA,
277 and the proceedings shall be conducted in English. The arbitrator
278 shall be empowered to grant any relief that a court could grant.

282 action.
283
284 15. If any provision of this Agreement is held to be
285 invalid, illegal
