to submit the matter to arbitration pursuant to Arizona law.
 
1.2. Applicable Law and Venue. This Agreement shall be interpreted
pursuant to the laws of the State of Arizona. Any arbitration or
litigation between the Parties shall be conducted in Pima County,
ARIZONA, and LICENSEE hereby submits to venue and jurisdiction in
Pima County, ARIZONA.
 
1.3. Non-Discrimination. The Parties agree to be bound by state and
federal laws and regulations governing equal opportunity and non-
discrimination and immigration.
 
1.4. Appropriation of Funds. The Parties recognize that performance
by ARIZONA may depend upon appropriation of funds by the State
