                                         Party</B>&rdquo; (subject to this Section 7.3(b)). The Entrusted Party shall provide
                                         the other party reasonable opportunity to review and comment on such prosecution efforts
                                         regarding such Joint Patents. The Entrusted Party shall provide the other party with
                                         a copy of material communications from any patent authority regarding such Joint Patents,
                                         and shall provide the other party with drafts of any material filings or responses to

                                         its sole discretion to abandon or not maintain any Patent within the Joint Patents anywhere
                                         in the world, then such Party shall provide the other Party (the &ldquo;Second Party&rdquo;)
                                         with thirty (30) days&rsquo; prior written notice of such determination (or such longer
                                         period of time reasonably necessary to allow the other party to assume such responsibilities)
                                         and shall provide the Second Party with the opportunity to prosecute and maintain such
                                         Patent at the Second Party&rsquo;s sole expense, and if the Second Party so requests,
                                         the First Party shall assign such Patent to the Second Party (if the Second Party is
                                         Rhizen, such Patent shall be included in the Rhizen Patents or if the Second Party is
                                         TGTX, in which case such patent will be included in the TGTX Patents).&nbsp; If one Party
                                         (the &ldquo;First Party&rdquo;) desires to file, in a particular jurisdiction, a patent
                                         application that claims priority from a Patent within the Joint Patents, the First Party
                                         shall provide written notice to the other Party (the &ldquo;Second Party&rdquo;) of such
                                         desire. Within fifteen (15) days of such written notice, the Second Party shall provide
                                         written notice to the First Party as to whether the Second Party agrees to file a patent
                                         application in such jurisdiction or not. In the event the Second Party agrees to such
                                         a filing, the Entrusted Party shall file such patent application in such jurisdiction.
                                         In the event the Second Party does not desire to file in such jurisdiction, the Second
                                         Party shall (i) provide the First Party with the opportunity to file and prosecute such

                                         application or a right to file such patent application to the First Party; and the First
                                         Party may file such patent application in such jurisdiction at its sole expense (in which

On determination of such an event, the JSC may have an option to provide TGTX with an extension of 12 months if TGTX pays Rhizen
