In consideration of the City's agreement to permit me to participate in this Dig, the receipt and sufficiency of which is hereby acknowledged, I agree as follows: 

1. I represent and warrant that I will be covered throughout the Dig by a policy of comprehensive health and accident insurance which provides coverage for illnesses or injuries I sustain or experience.

2. I, individually, and on behalf of my heirs, successors, assigns, and personal representatives, hereby release and forever discharge the City and its employees, agents, servants, officers, trustees, and representatives (in their official and individual capacities) and WMU from any and all liability, loss or damage that they or any of them incur or sustain as a result of any claims, demands, actions, causes of action, judgments, costs, or expenses, including attorney’s fees, which arise out of, result from, occur during, or are connected in any manner with my participation in the Dig and/or any travel incident thereto. 
3. I, individually, and on behalf of my heirs, successors, assigns, and personal representatives, hereby agree to indemnify, defend, and hold harmless the City and its employees, agents, servants, officers, trustees, and representatives (in their official and individual capacities) and WMU from any and all liability, loss, or damage that they or any of them incur or sustain as a result of any claims, demands, actions, causes of action, judgments, costs, or expenses, including attorney's fees, which arise out of, occur during, or are in any way connected with my participation in the Dig or any travel incident thereto.
