CESI's payment obligations commence upon the Effective Date of this Agreement and will terminate on the Payment and Royalty Termination Date, or until the cumulative payments, royalties, license fees and license royalties and sub-license fees and sub-license royalties paid to WGC hereunder total US $15,000,000 (Fifteen Million US Dollars), whichever occurs first. 2.4 License and Sub-Licenses. CESI may grant sub-licenses under ------------------------ Section 2.2 only as described in this Section 2.4. Prior to granting a sub-license under Section 2.2 or a license under the 793 Patent to gas turbine manufacturers and third party controls systems manufacturers for the sole purpose of such sub-licensees or licensees developing, manufacturing, selling, offering for sale, using, importing or servicing a control system for Xonon-equipped gas turbines (each such sub-license or license, a "Control System License," and each such sub-licensee or licensee, a "Control System Licensee"), CESI shall first use reasonable efforts to make the potential Control System Licensee aware of the benefits of purchasing such controls systems from WGC. Each Control System License must be subject to the following conditions: 2.4.1 the Control System Licensee may not sub-license any rights granted under a Control System License to this Agreement; and 2.4.2 the Control System License will only apply to control systems, or components thereof, for use with Xonon Systems. 2.5 Nomination Process. Prior to granting a Control System License to ------------------ any third party control systems manufacturer: 2.5.1 CESI shall provide WGC with a letter from a gas turbine manufacturer nominating that third party control systems manufacturer to provide controls systems for that gas turbine manufacturer; and 2.5.2 such Control System License will only apply to controls systems provided by the nominated third party controls systems manufacturer to that gas turbine manufacturer. 2.6 Control System License Fees.
