I have a paragraph for example below
Either party may terminate this Agreement by written notice at any time if the other party defaults in the performance of its material obligations hereunder. In the event of such default, the party declaring the default shall provide the defaulting party with written notice setting forth the nature of the default, and the defaulting party shall have thirty (30) days to cure the default. If after such 30 day period the default remains uncured, the aggrieved party may terminate this Agreement by written notice to the defaulting party, which notice shall be effective upon receipt.

and then I need the Entity label and Entity value
Entity value = thirty (30) days
Entity label = Termination Notice Period
and I want to frame it as a Entity recognition task, So could you please tell me how would you have been approached?
