The policies of liability insurance shall name UNOCAL and Hallwood, as defined in the SubLease Agreement, as an additional insured: with a Cross Liability Clause (Severability of Interest), and shall not exclude or restrict coverage based upon alleged or actual negligence of an additional insured. Sub-Lessee shall deliver to UNOCAL a certificate evidencing the policies, that UNOCAL and Hallwood are named as an additional insured under the policies and that coverage will not be canceled or materially changed prior to thirty (30) days' advance written notice to UNOCAL.

Any deductible amount is the responsibility of the Sublessee.
