terms or conditions of this Agreement and shall not limit or affect the meaning or construction of the terms and conditions hereof. 
 7.9 Word
Meanings. Words such as herein, hereinafter, hereof and hereunder refer to this Agreement as a whole and not merely to a section or paragraph in which such words appear, unless the context otherwise requires. The
singular shall include the plural, and each masculine, feminine and neuter reference shall include and refer also to the others, unless the context otherwise requires. 

7.10 Conflict or Inconsistency. In the event of any conflict or inconsistency between the terms and conditions of this Agreement and any terms
or conditions set forth in any purchase order or other document relating to the transactions contemplated by this Agreement, the terms and conditions set forth in this Agreement shall prevail.

 7.11 Counterparts. This Agreement may be executed in multiple counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and the same instrument. 
 7.12 Force Majeure. “Force
Majeure” means acts of God, wars (declared or undeclared and including the continuance, expansion or new outbreak of any war or conflict now in existence), revolution, civil commotion, acts of public enemy,
labor strikes (other than employees of the Affected Party, as defined herein), terrorism, embargo or acts of government in its sovereign capacity. Except as otherwise provided in this Agreement, in the event that a delay or failure of a Party (the
“Affected Party”) to comply with any obligation created by this Agreement is caused by Force Majeure, the Affected Party will, after giving prompt notice to the other Party ( the “Disadvantaged
Party”), be excused from such performance on a day-to-day basis during the continuance of such prevention, restriction, or interference (and
the Disadvantaged Party will likewise be excused from performance of its obligations on a day-to-day basis during the same period), provided, however, that the Affected
Party will use its best efforts to avoid or remove the causes of nonperformance and both Parties will proceed immediately with the performance of their obligations under this Agreement whenever the causes are removed or cease. If Force Majeure
conditions continue for more than 45 consecutive days or an aggregate 90 days in any 12-month period, then the Disadvantaged Party may terminate this Agreement in accordance with Section 6.4(c). 

7.13 Further Assurances. Each Party covenants and agrees that, subsequent to the execution and delivery of this Agreement and without any
additional consideration, it will execute and deliver any further legal instruments and perform any acts that are or may become reasonably necessary to effectuate the purposes of this Agreement. 

7.14 Dispute Resolution. 
 (a) Any disputes arising under
this Agreement or connected herewith that the Parties are unable to resolve amicably within thirty (30) days after written notice thereof from one Party to the other shall be settled, solely and exclusively, by an arbitration to be conducted by
one arbitrator in accordance with the Rules of Conciliation and Arbitration of the International Chamber of Commerce then in effect, excepting those disputes requiring injunctive relief, which shall be governed by Section 7.14(b). If the
Parties are unable to agree on a single arbitrator, then such binding arbitration shall be conducted before a panel of three (3) arbitrators that shall be comprised of one (1) arbitrator designated by each Party and a third arbitrator
designated by the two (2) arbitrators separately designated by the Parties. Unless the Parties agree otherwise, the arbitration proceedings shall take place in San Francisco, CA and, the arbitrator(s) shall apply the laws of the State of New
York and the United States without reference to conflicts of law rules that would result in the application of the laws of another jurisdiction, to all issues in dispute. All arbitration proceedings shall be conducted in English. The findings of the
arbitrator(s) shall be final and binding on the Parties. Judgment may be entered in any court of appropriate jurisdiction, or application may be made to that court for a judicial acceptance of the award and an order of enforcement, as the Party
seeking to enforce that award may elect. 
 (b) In the event of any breach by either Party of any of the provisions of this Agreement that would cause
immediate and irreparable injury to the other Party, the non-breaching Party shall be entitled to seek injunctive relief and any or all other remedies applicable at law or in equity in any court of applicable
jurisdiction.

 7.15 Attorneys’ Fees. If any arbitral or other proceeding is initiated by either of the
Parties, the prevailing Party shall be entitled to recover from the other Party reasonable attorneys’ fees and arbitration or proceedings costs in addition to any other relief that may be awarded. 

7.16 Remedies. All remedies set forth in this Agreement are cumulative and are in addition to any and all other remedies provided to either
Party at law or in equity. The failure of a Party to enforce, at any time, or for any period of time, any of the provisions of this Agreement, or of any breach hereof, shall not be construed as a waiver of such provision or subsequent breach of the
same or any other provision or of the rights of such Party thereafter to enforce such provision, nor shall either Party’s continued dealing with the other Party following a breach of any provision hereof be deemed to be a waiver of such or any
other breach.
