Institution may not store or use the Material at any facility outside the control of Institution. Institution shall comply with all applicable laws and regulations, and all written instructions from Lixte, in the storage, handling, use, return, and disposal of the Material. Institution agrees not to transfer the Material to any third party without the prior written permission of Lixte. Institution shall at all times be responsible for the compliance with this Agreement by Institution’s employees, representatives and/or any other person under its control and supervision who has access to the Material or Information. For the avoidance of doubt, no right is granted hereunder for any individual who leaves the employ of Institution to transfer or use any Material or Confidential to with any subsequent employer or institution.

5.       Intellectual Property Rights.

5.1.       Institution and Oncode acknowledge and agree that the Compound, Material, and Information are valuable business property of Lixte, subject to intellectual property rights owned by or licensed to Lixte. If the use of the Material or Information results in any Invention (defined below), Institution and Oncode agree to disclose promptly to Lixte any such Invention in confidence before otherwise disclosing the same publicly or to any third party, so that Lixte can determine whether such Invention should be the subject of a patent application. “Invention” means any invention, process, substance, or improvement, whether or not patentable, based on work conducted in the Study or otherwise invented through the use of, derived from, or which incorporates or comprises use of, any Material or Information, including without limitation any new use or improvement to any Material and/or any substance isolated, and all intellectual property rights therein and relating thereto.

5.2.       Inventorship of an Invention shall be determined in accordance with U.S. patent law. Except as otherwise specified in this Section 5, an invention shall be solely owned by Institution if conceived, reduced to practice or otherwise invented (“Invented”) solely by a representative of Institution, and jointly-owned by both Institution and Lixte if invented jointly by representatives of both Institution and Lixte, provided that any Invention that, in whole or part, comprises, or relates to or derives from the use of, the Compound (whether invented solely by Institution or jointly with Lixte or NKI) shall be jointly-owned by both Institution and Lixte.

5.3.       With respect to any Invention owned in whole or part by Institution (a “Institution Invention”), Institution and Oncode hereby grant to Lixte: (i) a non-exclusive, royalty-free and fully paid up, worldwide, irrevocable, non-transferable (except to the successor to Lixte’s business, whether by sale of all or substantially all of the equity or assets, by merger or otherwise) license under its rights in an Institution Invention to make, have made, use, import and otherwise practice such Institution Invention for any purpose relating to internal research or development activities and for any purpose related to the exploitation of the Compound and (ii) the exclusive option to obtain an exclusive license under Institution’s rights in any such Institution Invention for all purposes (including without limitation the commercial manufacture and sale of products and services) on reasonable commercial terms (the “Option”). Upon Lixte’s exercise of its Option, the Parties will promptly commence good faith negotiations in an attempt to reach an exclusive license agreement at a reasonable royalty rate satisfactory to both Parties (the approval of which is not to be unreasonably withheld, delayed or denied by Institution) and otherwise on other standard license terms. Should Lixte fail to exercise its Option within one (1) month, or the Parties negotiate in good faith but do not mutually agree and execute an exclusive license as set forth above within six (6) months from exercising the Option, Institution may grant a license under its rights in any such solely-owned Institution Invention to one or more third parties without Lixte’s consent, provided that for a period of six (6) months after the expiration of the negotiation period with Lixte, Institution may not offer to license any solely owned or jointly-owned Institution Invention to any third party on materially better terms than those last offered to Lixte without first offering such terms to Lixte, in which case Lixte will have a period of thirty (30) days in which to accept or reject the offer and provide further that Lixte shall have no obligation to grant to such third party licensee any license under the Compound or any Lixte patents. For the avoidance of doubt, in the event Lixte elects not to exercise the Option, or if the parties enter into an exclusive license but such exclusive license expires or is terminated for any reason, Lixte shall retain the perpetual non-exclusive license specified in subsection (i) above. Notwithstanding anything to the contrary herein, and to the extent Institution is legally able to do so, Lixte shall solely own any Invention made through activities in breach of this Agreement, including without limitation any use of the Compound, Material or Information outside the scope of the license granted hereunder.

5.4.       Institution shall not file any patent application for any Invention without giving adequate prior notice to Lixte of such Invention. If notwithstanding the foregoing, Institution files in its own name any application for patent for any Invention, it shall, and hereby does, assign to Lixte ownership or co-ownership, for as far as applicable, in accordance with this Section 5, more specifically Section 5.2.

5.5.       Lixte shall control the prosecution of all patents for any Inventions, at Lixte’s cost, with the cooperation of Institution, provided that Institution shall control the prosecution of any Invention that is solely owned by Institution and for which Lixte declines to exercises its licensing Option, in which case it is at the discretion of Institution whether or not to continue the prosecution or maintenance of such patents. Lixte shall keep Institution reasonable information of the progress of such patent prosecution.

5.6.       Notwithstanding anything to the contrary herein, the Parties have agreed to collaborate with respect a patent application that will cover the research conducted by the research group of Prof. R. Bernards (“Principal Investigator”) only prior to the Effective Date and directly relating to the subject matter of the Study, to include information and contributions by both Parties, and to file such application as a jointly-owned Invention. Such Invention and patent application shall be subject to the terms of this Agreement, including without limitation Section 5.3. Each Party shall execute and cause to be executed by its employees and agents all documents, and perform all acts, including providing reasonable assistance with the filing and prosecution of any patents, necessary to effect or evidence the ownership of any Invention as set forth in this Agreement, at the request and expense of the other Party.

6.       Confidentiality.

6.1.       Paragraphs 1 through 3 of the Reciprocal Non-Disclosure Agreement between the Parties dated ● (attached hereto as Exhibit B) are incorporated herein by reference as if full stated herein, with the term “Lixte” substituted for “Provider” and “Institution” substituted for “Recipient.” The Parties agree that the Compound, Material and Information (whether disclosed in writing, orally or through visual inspection) are the Confidential Information of Lixte, and the Study Results are the Confidential Information of both Parties, in each case including all copies of the foregoing and all summaries and notes thereof or derived therefrom whether created by Lixte or Institution.

6.2.       A recipient of Confidential Information hereunder shall use such information solely for purposes of this Agreement, and hold in confidence and not disclose to any third party such Confidential Information during the term hereof and for a period of five (5) years from the termination of this Agreement.

7.       Study Results and Publications.

7.1.       Institution shall keep Lixte reasonably informed about the progress of the Study and the research results thereof. Within sixty (60) days of completing the Study, Institution shall provide Lixte with a copy of the data, materials and other research results obtained from the use of the Compound or Confidential Information (“Study Data”).

7.2.       In order to protect Lixte’s proprietary and/or patent rights to the Compound and Information, Institution agrees to provide Lixte with an advance copy of any proposed publication or public disclosure (including abstracts, or presentation to a journal, editor, meeting, seminar or other third party) that makes reference to the Compound or Information, at least thirty (30) days prior to the proposed publication or public disclosure. If in the opinion of Lixte any such publication describes a patentable invention, Lixte shall have an opportunity to request that Institution delay the proposed publication or public disclosure until after a U.S. patent application has been filed. In no event shall the delay exceed sixty (60) days from the date that Institution provides Lixte with the advance copy of the proposed publication or public disclosure that makes reference to the Compound and Information. If Lixte determines such proposed publication or public disclosure contains any Confidential Information of Lixte, it shall notify Institution within such thirty (30) day review period and Institution shall delete such Lixte Confidential Information before proceeding with its planned publication. If a publication results from work using the Compound or Information, or based on any direct contribution made to the work by any Lixte scientists, Institution agrees to acknowledge Lixte and/or give credit to Lixte scientists as scientifically appropriate.

8.5.       Except under the indemnities in this Section 8, the aggregate liability of any Party for damages as described in Section 8.4 will not exceed in total the Budget.

9.       Term and Termination. This Agreement will commence on the Effective Date and terminate on its third anniversary, unless terminated earlier as permitted hereunder. Either Party may terminate this Agreement upon written notice in the event that the other Party is in material breach of this this Agreement and has failed to cure sure material breach within thirty (30) days of written notice of breach from the other Party. Lixte may terminate this Agreement immediately upon written notice in the event of a violation of law or Section 4.3 by Institution. Termination shall terminate all rights of Institution to use the Compound, Material and Information, but shall not relieve Institution of its obligations under this Agreement.
