A negotiated co-tenancy clause for use in a shopping center retail lease. This Standard Clause provides tenant protection by giving the tenant certain rights if a certain percentage of the other tenants in the shopping center cease operations during that tenant's lease term. This Standard Clause has integrated notes with important explanations and drafting and negotiating tips for both landlords and tenants. While retail leases are generally governed by state law, this jurisdictionally neutral clause is useful and relevant in every state.
