The Parties agree that, in the event of breach or threatened breach or intended breach of the Agreement, each Party, in addition to any other rights and remedies available to it at law or in equity, may seek injunctive or equitable relief without the necessity of posting bond or proving that it has no adequate remedy at law.

7. PATENTS, COPYRIGHTS AND TECHNOLOGY RIGHTS

7.1 Title to Inventions conceived and reduced to practice solely by University shall reside in University (“University Inventions”).  Title to all Inventions conceived and reduced to practice solely by Sponsor shall reside in Sponsor (“Sponsor Inventions”).  Title to all inventions and discoveries conceived and reduced to practice jointly by Sponsor and University shall reside jointly in Sponsor and University (“Joint Inventions”).  University hereby grants to Sponsor an exclusive first option to negotiate a royalty- bearing exclusive license for any invention or discovery that is conceived or reduced to practice during the term of this Agreement directly resulting from the performance of research hereunder to the extent that University is able to do so under applicable law.  It is contemplated that, in the majority of instances, Sponsor will be asked to determine whether it will exercise its option prior to the filing of the first patent application.  University reserves for itself a royalty-free, irrevocable license to make and use such University Inventions and Joint Inventions for its own research and educational purposes, but not for commercial purposes during the option period.  If a University Invention or Joint Invention arises from the Research Program, the Principal Investigator shall promptly submit an invention disclosure (xxxx://xxx.xxx.xxxxxx.xxx/XxxxxxxxXxxxx.xxx) to University’s Office of Technology Commercialization (“OTC”).  University will provide to Sponsor a full copy of such disclosure promptly after such disclosure is received by OTC.  Sponsor may review (and University shall provide to Sponsor) any and all patentability and freedom to operate opinions that have been commissioned by the University.  A Sponsor Entity shall then have ninety (90) days from receipt of such disclosure of any University Invention or Joint Invention to notify University of its desire to enter into such a license agreement, and a non-binding term sheet and thereafter a license agreement shall be negotiated in good faith within a period not to exceed six (6) months (“License Option Period”) from the applicable Sponsor Entity’s notification to University of its desire to enter into a license agreement, or such period of time as the parties shall mutually agree in writing.  The parties agree to negotiate, in good faith, a license agreement with terms and conditions substantially similar to existing license agreements between the parties, to the extent allowed by current law, University policy, and reasonable updates to financial terms.  During the License Option Period, University agrees that it will not offer its rights in University Inventions or Joint Inventions to any third party or negotiate with third parties with respect to those rights.  If the parties fail to enter into a license agreement within the License Option Period under the provisions of this Section 7.1, University rights in University Inventions and Joint Inventions shall be disposed of in accordance with University policies with no further obligations to Sponsor.

7.2 “Background Intellectual Property” (“BIP”) means intellectual property and the legal rights therein (including, but not limited to, inventions, patent applications, patents, copyrights, and any information embodying proprietary data such as technical data and computer software) of University developed or created by Principal Investigator(s) before the Effective Date of the Research Program and necessary for the full exercise of all intellectual property which is related to the Research Program.  University BIP is listed in Attachment B of this Agreement.  The Parties agree that nothing in this Agreement grants either Party any rights to any background intellectual property of the other Party created before the Effective Date of the Agreement.

7.3 The applicable Sponsor Entity has the right to elect to have patent applications filed on any University Invention or Joint Invention, and if it does so, then such Sponsor Entity shall reimburse University for all documented, out-of-pocket patent expenses incurred by University, including those for patentability opinions, within thirty (30) days of such Sponsor Entity’s receipt of an invoice from

5

University.  Such patent expenses shall include, but not be limited to, the cost of any prior activities investigating patentability of said invention before exercise of the option, such as search and opinion for patentability, that may have been performed by University pursuant to its arrival at a judgment of commercially exploitable status.  Following expiration of the License Option Period, and in the event that University grants a license to any University Inventions to a third party (the “Third Party License”), University shall pay to the applicable Sponsor Entity its reasonable costs incurred in connection with the preparation, filing, prosecution and maintenance of the licensed University Inventions or Joint Inventions paid under the Third Party License with the following priority for payment: i) in one full payment from the fees reimbursed to University by a third party under the executed license; or if necessary, ii) on a quarterly basis, a royalty (the “Third Party Royalty”) equal to one hundred percent (100%) of University’s net licensing revenue attributable to the Third Party License (including license fees, royalties, revenue sharing, milestone payments and other monetary payments) until such time as University has paid to such Sponsor Entity aggregate Third Party Royalties equal to such Sponsor Entity’s reasonable costs incurred in connection with the preparation, filing, prosecution and maintenance of the licensed University Inventions.

7.4 At its discretion, University may allow the applicable Sponsor Entity to instruct Prosecution Counsel directly for University Inventions and Joint Inventions, provided, that prior written approval is obtained and the Prosecution Counsel remains counsel to the University with an appropriate contract (and shall not jointly represent such Sponsor Entity unless requested by such Sponsor Entity and approved by University, not to be unreasonably denied, and an appropriate engagement letter and conflict waiver are in effect).  If such Sponsor Entity wishes to instruct Prosecution Counsel directly or change Prosecution Counsel, such Sponsor Entity may request to do so by following the University’s procedures for such.  Subject to the terms herein University reserves in its sole discretion the ability to change Prosecution Counsel and to approve or disapprove any requested changes by such Sponsor Entity.  The Parties agree that they share a common legal interest to get valid enforceable patents in strategically important countries and that both Parties will maintain as privileged all information received pursuant to this Section 7.  Each Party agrees to cooperate fully in the preparation, filing, and prosecution of any patent and any joint patent, as described herein.  Such cooperation includes without limitation executing all papers and instruments, or requiring its representatives to execute such papers and instruments, so as to effectuate the ownership of such intellectual property rights.

7.5 Notwithstanding anything to the contrary set forth herein, , University hereby grants to Sponsor a perpetual, irrevocable, worldwide, non-exclusive, royalty free right and license, with the right to sublicense to third parties through multiple tiers, to use the Data and Results for any and all purposes.  Data and Results mean all data, information and results arising from the Research Program that are included in the Research Program deliverables but are not inventions and discoveries for which a patent invention disclosure is made.

8. LIABILITY

8.1 Sponsor agrees to defend (and subject to the statutory duties of the Texas State Attorney General to defend University, if applicable),indemnify and hold harmless System, University, their Regents, officers, agents and employees from any liability, loss or damage they may suffer as a result of third party claims, demands, costs or judgments against them arising out of the activities to be carried out pursuant to the obligations of this Agreement, including but not limited to the use by Sponsor of the results obtained from the activities performed by University under this Agreement; provided, however, that the following is excluded from Sponsor’s obligation to defend, indemnify and hold harmless:
