Summary:
WIN's only two options in bankruptcy are an assumption or rejection of the lease.
Outside of bankruptcy, WIN and UNIT could negotiate a new lower lease payment but it's too late for that and wouldn't stave off a BK filing.
A payment default under the lease would be deemed a lease termination under the Master lease and allow UNIT to put WIN's business to another party.
Practical seniority of the UNIT lease with WIN.
