Early lease Termination

[Gracy Josh]

I have rented a house to a tenant and the lease agreement states that 1 month rent + 2 months notice in case of early termination. The current lease ends on oct 31 2014. The tenant has given notice today and since they will be obliged for 2 months notice till oct 4th and the balance days for lease ending is 27 days for which they are asking to waive the early termination fee. I'm new to the rental process, Please help me on how to handle this case?
