Dear In case you have not had an opportunity to read through the Master Lease, please note that there is an insurance clause that requires the tenant to carry public liability insurance of $000,000/$0,000,000 and property damage insurance of $000,000. The landlord , (name), must be named as additional insured. Inasmuch as we are sub-leasing these offices to you, please have (name) named also, and ask your agent to send us a notice to that effect. Thank you very much.
