use obligations with respect to the Confidential Information shall terminate five (5) years after the termination date of this Agreement. Notwithstanding anything to the contrary in this Agreement, 2 Blades may disclose Confidential Information of CPS (a) to the extent required by [*****], and (b) provided by CPS in its reports to 2 Blades pursuant to Section 2.8, as such information relates directly to TAL Nucleases or any invention disclosed or claimed in the Licensed Patents, in 2 Blades’ reporting and marketing activities in a form approved in writing by CPS (which approval shall not be unreasonably withheld).

9.3 Disclosures to Employees. The recipient agrees to advise its officers and employees who need to know Confidential Information of these confidentially and limited use obligations and further agrees, prior to any disclosure of Confidential Information to such individuals, to cause them to be bound by the same obligations of confidentially and limited use as those contained in this Agreement.

9.4 Return of Confidential Information.

ARTICLE 10 DISPUTE RESOLUTION

10.1 Meeting. In the event of any dispute relating to this Agreement, including the validity, scope, interpretation or application of this Agreement, each Party agrees to notify the other Party of the nature of the dispute in writing and arrange to meet and confer at the senior management level to try to resolve such dispute by good faith negotiations. If the Parties have not resolved the dispute within ninety (90) days of the date of written notice, the Parties agree to proceed by arbitration under the Rules of Arbitration (“Rules”) of the International Chamber of Commerce (Paris) (“ICC”) by a single arbitrator appointed in accordance with said Rules, if not otherwise stipulated in Section 10.2.

10.2 Arbitration Procedures. There shall be one arbitrator, who shall be selected jointly by the Parties within twenty (20) days of receipt by respondent of a copy of the demand for arbitration. Any arbitrator not timely appointed shall be appointed by the ICC from the ICC’s large, complex case panel, using the listing, ranking and striking procedure in the Rules, with each Party having a limited number of peremptory strikes. Any arbitrator appointed by the ICC shall have significant experience with the arbitration of similar large, complex, commercial disputes. The arbitration proceeding shall be conducted in the English language. The arbitration proceeding shall be held in Chicago, Illinois, USA; provided that the Parties may agree in writing to conduct individual hearings in other locations, in accordance with the Rules of the ICC. The Parties agree that only documents directly relevant to the issues in dispute must be produced in any such arbitration. The arbitration shall be conducted as expeditiously as practicable, and the Parties and the arbitrator shall use their best efforts to hold the hearing on the merits no later than ninety (90) days after the appointment of the arbitrator, and the arbitrator shall use its best efforts to issue a final award within twenty (20) days after the close of the hearing. In addition to damages, the arbitral tribunal may award any remedy provided for under applicable law and the terms of this Agreement, including specific performance or other forms of injunctive relief. The arbitral tribunal is not empowered to award damages in excess of compensatory damages, and each Party hereby irrevocably waives any right to recover punitive, treble or similar damages with respect to any arbitrated dispute. The arbitration award shall be in writing and shall briefly state the findings of fact and conclusions of law on which it is based. The arbitration award shall be final and binding on the Parties. The award may be entered and enforced in any court having competent jurisdiction. The administrative charges, arbitrators’ fees, and related expenses of any arbitration shall be paid equally by the Parties, but each Party shall be responsible for any costs or expenses incurred in presenting such Party’s case to the arbitrators, such as attorney’s fees or expert witness fees; provided, however, that if in the opinion of the arbitrator any claim by a Party hereto or any defense or objection thereto by the other Party was unreasonable, the arbitrator may in its sole discretion assess as part of the award all or any part of the arbitration expenses of the other Party as applicable (including reasonable attorneys’ fees) and the fees and expenses of the

arbitrator and the ICC against the Party raising such unreasonable claim, defense or objection. Notwithstanding the Parties’ agreement to arbitrate, the Parties hereby agree that either Party may apply to any court of law or equity of competent jurisdiction for specific performance or injunctive relief to enforce or prevent any violation of the provisions of Article 9 of this Agreement. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitral tribunal shall have full authority to grant provisional remedies and to direct the Parties to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any Party to respect the arbitral tribunal’s orders to that effect.

10.3 IP Matters. Notwithstanding the Parties’ agreement to arbitrate, unless the Parties agree in writing in any particular case, claims and disputes between the Parties relating to or arising out of, or for which resolution depends on a determination of the interpretation, validity, enforceability or infringement of, patents or trademarks or the misappropriation of trade secrets, shall not be subject to arbitration under this Agreement, and the Parties may pursue whatever rights and remedies may be available to them under law or equity, including litigation in a court of competent jurisdiction, with respect to such claims and disputes.

ARTICLE 11 MISCELLANEOUS

11.1 Relationship of Parties. The relationship of the Parties is that of independent contractors, and nothing herein shall be construed as establishing one Party or any of its employees as the agent, legal representative, joint venture, partner, employee, or servant of the other Party.

11.2. Assignment. This Agreement and the licenses granted herein are not assignable by either Party to any person or entity without the prior written consent of the other Party (which consent shall not unreasonably be withheld), provided, however, that either Party may assign this Agreement, without such consent, upon a transfer or sale of all or substantially all of the business of such Party to which this Agreement relates to a Third Party (the “Transfer or Sale”), whether by merger, sale of stock, sale of assets or otherwise, provided in each case that (i) such Party notifies to the other Party within thirty days of a Transfer or Sale and assignment of this Agreement, and (ii) the assignee delivers to the other Party a written instrument unconditionally agreeing to be bound by this Agreement; provided further that in any case the non-assigning Party shall retain all the benefits of the rights and licenses granted to it under this Agreement. The terms and conditions of this Agreement will be binding on and inure to the benefit of the successors and permitted assigns of the Parties. Any attempted assignment in violation of this Section 11.2 shall be null and void.
