The injunction stays a landlord's termination of a leasehold while the propriety of the underlying default is litigated. The injunction does not nullify the remedies to which a landlord is otherwise entitled under the parties' contract. Instead, it maintains the status quo so that a commercial tenant, when confronted by a threat of termination of its lease, may protect its investment in the leasehold by obtaining a stay tolling the cure period so that upon an adverse determination on the merits the tenant may cure the default and avoid a forfeiture. In order t o obtain a Yellowstone injunction, the tenant must demonstrate that (1) it holds a commercial lease; (2) it received from the landlord either a notice of default, a notice to cure, or a threat of termination of the lease; (3) it requested injunctive relief prior to both the termination of the lease and the expiration of the cure period set forth in the lease and the landlord's notice to cure; and (4) it is prepared and maintains the ability to cure the alleged default by any means short of vacating the premises.
