A restriction in the language of a conveyance that causes the created interest to expire automatically upon the occurrence of a stated event. The restriction supplies a terminability beyond the normal duration of the estate. Words such as so long as, while, during, or until typically signal the presence of the restriction.
Serena Soto conveyed Blackacre to Silverline Industries by deed stating that the land was granted so long as it remained used for manufacturing.

…employment context. We discern no basis for departing from otherwise applicable general contract principles. The doctrine that special limitations should be placed on the enforceability of employment security agreements arose during the late 19th century in the context of interpretation of contracts which promised "permanent"…
