(c) any other form of insurance and such higher limits as the lessor requires from time to time in the form, amount and risks of insurance against which a prudent lessee would insure. A model certificate of insurance is attached as Appendix “C”. The Tenant and its licensees and guests are bound by all appropriate arrangements that the Lessor may make from time to time, which shall be communicated in writing to the Tenant, including those referred to in Annex “B”. All these provisions are considered to be an integral part of the rental agreement. Nothing in this rental agreement is interpreted in such a way that the lessor is required to impose such rules on other tenants in the building, and the lessor is not held liable to the tenant for violations of the rules by these tenants or by their invited or licensed holders. If ninety (90) days before the extension period, the lessor and the tenant have not reached an agreement on the amount of that basic rent, that basic rent shall be decided by binding arbitration in accordance with Article 21.2, provided that the annual base rent to be paid during the extension period is not less than the basic annual rent to be paid during the the last year of the term; 10. Modifications, additions or modifications made to the partitions or subdivisions of the premises during the term of the rental contract are the responsibility of the lessee, at the request of the lessee, but are subject to the authorization and instructions of the lessor. At the end of the term of a fixed-term rental contract, the owner and the tenant can agree on another temporary term or the lease continues from month to month. . . .
