If we want a love message to be heard, it has to be sent out. To keep a lamp burning, we have to keep putting oil in it.
An exculpatory clause is a contract provision that relieves one party of liability if damages are caused during the execution of the contract. The party that issues the exculpatory clause is typically the one seeking to be relieved of the potential liability. For example, a venue may print an exculpatory clause on tickets it sells for a concert, indicating that it is not responsible for personal injury caused by employees or others during the show.
