9.1          Arbitration.  


 


(a)          Any
dispute arising out of or relating to this Agreement (including the Exhibits referenced herein, and the Ancillary Agreements) that
cannot be resolved in thirty (30) days through good faith negotiation and discussion among the Parties shall be finally settled
by arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules using the Expedited
Procedures then in effect (the “Arbitration Rules”).  The arbitration shall be conducted in the County
and State of New York, unless otherwise agreed by the Parties in writing.  The arbitration shall be conducted in the
English language. 


 


(b)          The
arbitration shall be conducted by a single, neutral arbitrator (“Arbitrator”) selected as follows: Within ten
(10) days after receipt of an arbitration notice from a Party, the Parties shall attempt in good faith to agree on an Arbitrator.  If
the Parties do not agree on an Arbitrator within ten (10) days after receipt of an arbitration notice, the Parties shall exchange
lists containing the names of three (3) candidates proposed by each Party to serve in such capacity.  No later than the
five (5) days after the exchange of each Party’s list of candidates, each Party shall deliver to the other a list ranking
all six (6) candidates proposed by the Parties in order of preference (one (1) being the most preferred and six (6) being the least

preferred).  The
candidate with the lowest aggregate ranking on the Parties’ lists shall serve as the Arbitrator (with the candidate whose
last name comes first alphabetically being chosen in case of a tie).  If any candidate selected in accordance with the
procedures provided in this Section is unable or unwilling to act as the Arbitrator, the candidate whose ranking is next lowest
shall be approached until an Arbitrator is selected.  If none of the candidates proposed by the Parties is capable or
willing to serve as the Arbitrator, the Parties may either agree to repeat the process until an Arbitrator is selected or, at the
election of either Party, proceed in accordance with the Arbitration Rules.  


 


(c)          The
decision or award of the Arbitrator shall be final, binding and incontestable and may be used as a basis for judgment thereon in
any jurisdiction. The Parties hereby expressly agree to waive the right to appeal from the decision of the Arbitrator. Accordingly,
there shall be no appeal to any court or other authority (government or private) from the decision of the Arbitrator, and the Parties
shall not dispute nor question the validity of such decision or award before any regulatory or other authority in any jurisdiction
where enforcement action is taken by the Party in whose favor the decision or award is rendered, except in the case the decision
or award was procured by fraud.  The Arbitrator shall, upon the request of either Party, issue a written opinion of the
findings of fact and conclusions of law and shall deliver a copy to each of the Parties.  Each Party shall bear its own
costs and attorneys' fees, and the Parties shall equally bear the fees, costs, and expenses of the Arbitrator and the arbitration
proceedings; provided, however, that the Arbitrator may exercise discretion to award costs, including reasonable and necessary
attorneys' fees, to the prevailing Party. 


 


9.2          Jurisdiction/Venue/Enforcement
of Award.  The Parties consent and submit to the exclusive personal jurisdiction and venue of the Supreme Court of
the State of New York and the United States District Court for the Southern District of New York, each located in County of New
York, State of New York, to compel arbitration in accordance with this Agreement, to enforce any arbitration award granted pursuant
to this Agreement, including, any award granting equitable or injunctive relief, and to otherwise enforce this Agreement and carry
