Fixed Rent for the Storage Space shall be payable by check drawn on a bank that is a member of the New York Clearinghouse Association, or on any other bank reasonably acceptable to Landlord either having an office in New York City or which is chartered as a national banking association, or by wire transfer of immediately available funds.

     3. Electricity; Elevator Service.

     (a) Landlord shall provide, at no additional cost to Tenant, electricity sufficient for the lighting of the Storage Space.

2

required). Such elevator service shall be subject to such rules and regulations as Landlord may promulgate from time to time with respect thereto. Landlord shall have the right to change the operation or manner of operation of any of the elevators in the Building, to temporarily discontinue the use of any one or more cars in any of the passenger, freight or truck elevator banks, and/or to permanently or temporarily discontinue the use of any one or more cars in any of the freight or truck elevator banks, provided that Tenant shall continue to be provided with adequate freight elevator service, taking into account Tenant’s use of the Storage Space for the uses permitted hereunder.

     (c) Except as provided in this Section 3, Landlord shall not be required to provide any services to the Storage Space.

     4. Condition of Storage Space; No Landlord’s Work. Tenant has examined the Storage Space and agrees to accept possession of the Storage Space in its “as is” condition on the Effective Date, and further agrees that Landlord shall have no obligation to perform any work, supply any materials, incur any expenses or make any installations in order to prepare the Storage Space for Tenant’s use. The taking of possession of the Storage Space by Tenant shall be conclusive evidence as against Tenant that at the time such possession was so taken, the Storage Space was in good and satisfactory condition.

     5. Consents and Approvals. Each of Landlord and Tenant represents and warrants to the other that there are no consents or approvals of any individual or entity which have not been obtained and which are required for the entering into of this Amendment and the completion of the transactions contemplated hereby on the part of Landlord or Tenant, as the case may be.

     6. Brokerage. Each of Landlord and Tenant represents and warrants to the other that it has dealt with no broker, agent or other person in connection with this transaction and that no broker, agent or other person brought about this transaction, other than Landlord’s leasing agent for the Building, CB Richard Ellis Real Estate Services, Inc., and Tenant’s agent, Newmark & Company Real Estate, Inc. (collectively, “Broker”). Landlord has agreed to pay a fee to Broker in connection with this Amendment and the transactions contemplated hereby pursuant to a separate written amendment. Each of Landlord and Tenant agrees to indemnify and hold the other harmless from and against any claims by any other broker, agent or other person claiming a commission or other form of compensation by virtue of having dealt with the indemnifying party with regard to this transaction. The provisions of this Section 6 shall survive the expiration or sooner termination of the Lease.

     7. Relocation. Landlord may at its option, at any time during the Term on not less than thirty (30) days prior notice to Tenant (except in the event of an emergency) relocate the Storage Space to another area of the Building designated by Landlord (the “Substitute Space”), provided that the Substitute Space is of a comparable size to the Storage Space, and such relocation is performed at Landlord’s expense. Landlord shall use reasonable efforts to minimize the duration of the relocation of the Storage Space to the Substitute Space, provided that Landlord shall have no obligation to employ contractors or labor at overtime or other premium pay rates or to incur any other overtime costs or additional expenses whatsoever. If Landlord moves Tenant to the Substitute Space, the Lease, as modified by this Amendment,

3

and each of the terms, covenants and conditions thereof and hereof shall remain in full force and effect and be deemed applicable to the Substitute Space in lieu of the Storage Space, and the Substitute Space shall thereafter be deemed to be the Storage Space as though Landlord and Tenant had entered into an express written amendment of the Lease with respect thereto.

     8. No Liability Of Landlord. Except and to the extent otherwise expressly provided in the Lease, Landlord shall not have any obligations with respect to any of Tenant’s Property Tenant stores in the Storage Space, nor shall Landlord be responsible for any damage that may be caused to such Tenant’s Property.
