Section 9.02. This Agreement does not in any way create a relationship of principal and agent, partnership or
joint venture between the Parties. Neither Party shall under any circumstances act as, or represent itself to be, the other Party. 

Section 9.03. Any notice, report or other document required or
permitted hereunder shall be written in English, and shall be sufficiently given when personally delivered, delivered by overnight courier or mailed prepaid first class registered or certified mail and addressed to the Party for whom it is intended

 Section 9.04.
Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement or portion thereof, or the application thereof to any person or
circumstance or in any country contravenes a law of any country (or political subdivision thereof) in which this Agreement is effective or is held to any extent invalid or unenforceable by a court of competent jurisdiction, the remaining provisions
of this Agreement (or of such provision) and the application thereof to other persons or circumstances or in other countries shall not be affected thereby, and this Agreement shall be modified with respect to its application in such jurisdiction,
but not in jurisdictions where such provision is valid, to conform with such law.

the subject matter hereof and supersedes all prior agreements, express or implied, and oral or written.

original, but all of which together shall constitute a single instrument. 
 Section 9.10. Any
dispute, controversy or difference arising out of, in relation to or in connection with, this Agreement shall be settled in good faith between the Parties. If the Parties fail to resolve such dispute, controversy or difference through the good faith
negotiations, it shall be finally settled by arbitration in Tokyo, Japan in accordance with the Rules of Arbitration of the International Chamber of Commerce for the time being in force by a panel of three (3) arbitrators. The language of the
arbitration shall be English. The prevailing Party shall be entitled to receive from the losing Party reimbursement for all costs incurred in such arbitration proceedings, including reasonable attorneys’ fees. The decision and award of the
arbitration shall be final and binding, and shall be enforceable in any court of competent jurisdiction.

disclose or transfer, without the prior written consent of the other Party, such terms or any part thereof to any third party, except 
 (a)
as otherwise may be required by law, order or regulation; or 
 (b) to any competent court, regulatory authority or governmental agency
which has ordered the same to be produced; provided, however, that the Party who has been so ordered shall promptly notify the other Party of such order and use its best efforts to preserve the confidentiality thereof to the extent possible
