Early Termination in BP lease documents?

[Curran D Bishop]

I have a tenant in Illinois who needs to break his lease 2 months early. I'm not looking to make money off him; but do need to have the discussion with him that he's breaking the lease and there are consequences to that. We're just using the Illinois lease that BP puts out (https://app.box.com/s/r0b3spxpse7jc0qe42tz95f056yand9h), but I can't find any specific penalties for early termination in there. Throughout the lease it's clear that the lease is in force until terminated, but I can't find specific enforcement/termination clauses. Can anyone point me to the right part of the document? Is this just an oversight?
