It is agreed by Institution that (without limitation) publication of an article substantially containing the information in the draft article provided to Company by Institution counsel on or about June 30, 2015 shall constitute such publication of Study results. After such publication of Study results, Company shall be free to disclose publicly information in the Deliverables in compliance with all applicable laws and Study consent forms. Institution shall provide Company with copies of Institutional Review Board approved informed consent templates for the Study, and, at the request of Company within the next 2 years from the CTA Amendment Effective Date, redacted copies of the Study informed consent forms in the possession of the Institution, or study sites, with fully-burdened costs and overhead to be pay by the Company. It is agreed, however, that under no circumstances will Company state or overtly imply in any publication or other published announcement that Institution has approved any product. Institution hereby grants Company (and its Affiliates and Sublicensees, as defined in the License Agreement) the non-exclusive perpetual, transferable rights, sublicenseable through multiple tiers of sublicensees, to use all information in the Deliverables for all purposes relating to development, registration and commercialization of Licensed Products in the Field of Use, but subject to the foregoing confidentiality obligations (prior to publication of the Study results), and in compliance with all applicable laws and Study consent forms. Institution hereby grants Company (and its Affiliates and Sublicensees, as defined in the License Agreement) the rights of reference to the Institution's IND for the Study and the Deliverables for the development, registration and commercialization of products licensed to Company under the License Agreement in accordance with the terms in Section 3.4. Initial Study data validation and review shall be done on behalf of Company promptly after receipt of the Deliverables by a third party consultant selected by and employed with Company (after consultation with UCLA), separate and apart from consultant hired to Institution’s research team as set forth in 3.1 above. Company shall own all reports, results and analysis resulting from its consultant's analysis and review (the "Analysis") and the MRI Analysis of the third party in 3.1 (g), and Institution assigns to Company its entire rights in the Analysis (but excluding any patent rights and any rights in the Study data). Institution covenants that it shall not conduct any review or analysis of the MRI Analysis until the date 90 days after delivery of the MRI Analysis to Company under Section 3.1(g). Company and its affiliates and sublicensees may use such Analysis with respect to Estriol in Field of Use, shall have the rights to disclose it to its Affiliates and Sublicensees (as those terms are used in the License Agreement), and to entities whom are believed in good faith to be potential development partners, subject to appropriate confidentiality obligations and other identified state and federal regulatory constraints, including but not limited to, HIPAA and CMIA. Company shall disclose the Analysis to the Institution in confidence, and shall ensure that the Deliverables and Analysis are not publicly disclosed until Principal Investigator is given a reasonable opportunity to publish on the clinical data, subject to the right of Company to remove Company Proprietary Information, and to request that patent applications be filed by the Regents based on any data, as provided in Article 4 below. Notwithstanding the foregoing, the Institution can use the Analysis in order to ensure the health and safety of the subjects enrolled in the Study."

Such costs include but are not limited to the costs incurred to redact patient identifying information from databases and patient case report forms, and (if applicable) training Company or a third party consultant to use the databases. The Institution shall invoice Company promptly for such costs, accompanied by such supporting documentation for such costs as Company may reasonably request."

The Institution shall provide to Company copies of all such regulatory documentation filed with the FDA under the IND upon reasonable request, which shall redacted in order to comply with laws and regulations regarding privacy of patient information, such redactions at Company's sole expense, including 26% overhead at the Institution, and subject to applicable law or regulation. The Regents will use reasonable good faith efforts to determine if they can agree not to grant to any other commercial party a right of reference to any such regulatory documentation filed with the FDA regarding the FDA in the Field of Use, to the extent permitted by law, contractual obligations, and The Regents’ policy, for a period of up to 5 years. At Company's request, and provided that Institution can so agree, The Regents will provide Company such written agreement, for the maximum period (not to exceed 5 years) that The Regents can so agree not to grant such rights to other commercial parties."
