2.2. Exclusivity. The License is exclusive for Institute Patent Rights, Institute Technical Information (and for Improvements to the extent they are not embodied in issued patent claims) in the Field of Use, except that Institute may use the Institute Patent Rights, Improvements and Institute Technical Information for its own non-commercial educational and research purposes. On or after the Effective Date, Institute shall have no right to grant a license to the Institute Patent Rights or Institute Technical Information in the Field of Use to any person or entity.

2.3. U.S. Government Rights. Licensee or its Affiliates acknowledge that pursuant to Public Laws 96-517, 97-256 and 98-620, codified at 35 U.S.C. 200-212, the United States government retains certain rights in intellectual property funded in whole or part under any contract, grant or similar agreement with a Federal agency.

The License is expressly subject to all applicable United States government rights as provided in the above-mentioned laws and any regulations issued under those laws, as those laws or regulations may be amended from time to time.

2.4. Sublicense Conditions. The right to sublicense granted to Licensee under Section 2.1 is subject to the following conditions:

2.4.2 Within [**] days after Licensee enters into any Sublicense, Licensee shall deliver to Institute a complete copy of the Sublicense written in the English language (receipt of a Sublicense shall not constitute an approval of the Sublicense or a waiver of any of Institute’s rights or Licensee’s obligations under this Agreement).

Licensee shall consult with Institute in such prosecution and maintenance, and shall diligently seek strong and broad claims under the Institute Patent Rights and shall not abandon prosecution of any Institute Patent Rights without first notifying Institute in a timely manner of Licensee’s intention and reason therefore, and providing Institute with reasonable opportunity to assume responsibility for prosecution and maintenance of the Institute Patent Rights. Licensee shall identify all claims (or potential for claims it is aware of) which are wholly or partially outside of the Field of Use, and abide by all requests of Institute regarding prosecution of claims which are wholly or partly outside of the Field of Use. If the Institute believes, in good faith and after consultation with Licensee, that Licensee is not fulfilling its duties under this Article, then Institute may resume responsibility for prosecution of the patents, and Licensee shall reimburse Institute for all costs expended by Licensee in prosecuting the patents.

ARTICLE 7

7.2. Prosecution by Licensee. Licensee may prosecute such infringement at its own expense. Licensee shall not settle or compromise any such suit in a manner that imposes any obligations or restrictions on Institute without Institute’s prior written permission, which permission shall not be unreasonably withheld (provided however that no permission shall be required for Licensee to grant a non-royalty bearing Sublicense as part of such settlement if Licensee reasonably determines that such grant is necessary or appropriate to avoid litigation or similar controversy).

BY WAY OF EXAMPLE BUT NOT OF LIMITATION, INSTITUTE MAKES NO REPRESENTATIONS OR WARRANTIES: (a) OF COMMERCIAL UTILITY; (b) OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE; OR (c) EXCEPT AS SET FORTH IN SECTION 8.1.1, THAT THE USE OF THE INSTITUTE PATENT RIGHTS, INSTITUTE TECHNICAL INFORMATION, INSTITUTE LICENSED PRODUCTS OR ANY TECHNOLOGY LICENSED UNDER THIS AGREEMENT WILL NOT INFRINGE ANY PATENT, COPYRIGHT, TRADE SECRET OR TRADEMARK OR OTHER PROPRIETARY OR PROPERTY RIGHTS OF OTHERS. INSTITUTE SHALL NOT BE LIABLE TO LICENSEE, AFFILIATES, LICENSEE’S SUBLICENSEES OR THEIR RESPECTIVE SUCCESSORS OR ASSIGNS OR ANY THIRD PARTY WITH RESPECT TO: ANY CLAIM ARISING FROM USE OF THE INSTITUTE PATENT RIGHTS, INSTITUTE TECHNICAL INFORMATION, INSTITUTE LICENSED PRODUCTS OR ANY TECHNOLOGY LICENSED UNDER THIS AGREEMENT OR FROM THE MANUFACTURE, USE OR SALE OF INSTITUTE LICENSED PRODUCTS; OR ANY CLAIM FOR LOSS OF PROFITS, LOSS OR INTERRUPTION OF BUSINESS, OR FOR INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES OF ANY KIND EXCEPT TO THE EXTENT THAT ANY SUCH CLAIM IS ATTRIBUTABLE TO A BREACH BY INSTITUTE OF SECTION 8.1.1.

8.2. Indemnification. Licensee shall indemnify, defend and hold harmless Institute, its trustees, officers, agents and employees (individually, an “Indemnified Party”, and collectively, the “Indemnified Parties”), from and against any and all liability, loss, damage, action, claim or expense suffered or incurred by the Indemnified Parties (including attorneys’ fees and expenses) (individually, a “Liability”, and collectively, the “Liabilities”) that results from or arises out of: (a) the development, use, manufacture, promotion, sale or other disposition of any Institute Technical Information, Institute Patent Rights, or Institute Licensed Products by Licensee, its Affiliates, its assignees, Sublicensees, vendors or other third parties; (b) any breach by Licensee or its Affiliates or Sublicensees of this Agreement; and (c) the enforcement by an Indemnified Party of this Section 8.2.

8.2.1 Any product liability or other claim of any kind related to the use by a third party of a Institute Licensed Product that was manufactured, sold or otherwise disposed by Licensee, its Affiliates, its assignees, Sublicensees or vendors;

8.3.2 A claim by a third party that the Institute Technical Information or Institute Patent Rights or the design, composition, manufacture, use, sale or other disposition of any Institute Licensed Product infringes or violates any patent, copyright, trade secret, trademark or other intellectual property rights of such third party, except to the extent such claim is attributable to a breach of Section 8.1.1; and

8.2.3 Clinical trials or studies conducted by or on behalf of Licensee, its Affiliates, its assignees, Sublicensees or agents relating to the Institute Technical Information, Institute Patent Rights or Institute Licensed Products, including, without limitation, any claim by or on behalf of a human subject of any such clinical trial or study, any claim arising from the procedures specified in any protocol used in any such clinical trial or study, any claim of deviation, authorized or unauthorized, from the protocols of any such clinical trial or study, and any claim resulting from or arising out of the manufacture or quality control by a third party of any substance administered in any clinical trial or study provided, that Licensee shall have no obligation to indemnify any Indemnified Party to the extent that any loss or damage is attributable to the negligence or misconduct of such Indemnified Party or its employees or representatives.

-14-

8.3. Rights of Institute in Liability Action.

If Licensee fails or declines to assume the defense of any such claim or action within [**] days after notice thereof, then Institute may assume the defense of such claim or action for the account and at the risk of Licensee, and any Liabilities related thereto shall be conclusively deemed a liability of Licensee. The indemnification rights of Institute or other Indemnified Party contained herein are in addition to all other rights that such Indemnified Party may have at law or in equity or otherwise.

8.4. Insurance.

8.4.1 Licensee and any Affiliate shall procure and maintain a policy or policies of comprehensive general liability insurance, including broad form and contractual liability, in a minimum amount of $[**] combined single limit per occurrence and in the aggregate as respects personal injury, bodily injury and property damage arising out of such party’s performance of this Agreement.

Such certificates shall provide that the insurance carrier(s) notify Institute in writing at least [**] days prior to cancellation or material change in coverage.

8.4.4 Institute may periodically review the adequacy of the minimum limits of liability insurance specified in this Section, and Institute reserves the right to request Licensee and any Affiliate to adjust the liability insurance coverages. Licensee will consider any reasonable request to adjust the liability insurance coverages. The specified minimum insurance amounts do not constitute a limitation on the obligation of Licensee and any Affiliate to indemnify Institute under this Agreement.

Without limiting the foregoing, it is understood that this Agreement may be subject to United States laws and regulations controlling the export of technical data, computer software, laboratory prototypes and other commodities, articles and information, including the Arms Export Control Act as amended in the Export Administration Act of 1979, and that the parties’ obligations are contingent upon compliance with applicable United States export laws and regulations. The transfer of certain technical data and commodities may require a license from the cognizant agency of the United States Government and/or written assurances by Licensee, its Affiliates and/or Sublicensees that Licensee shall not export data or commodities to certain foreign countries without prior approval of such agency. Institute neither represents that a license is not required nor that, if required, it will issue.
