(C) Landlord agrees that it shall reimburse Tenant for Work Cost (as hereinafter defined) for work performed by Tenant (“Tenant’s Initial Work”) performed in the demised premises, as provided in this subparagraph:

(i) Tenant’s Initial Work shall consist of the labor and materials and architectural services (exclusive of labor and materials and such services used to furnish or install trade fixtures, furniture, furnishings, moveable equipment and any personal property whatsoever) used by Tenant to construct permanent leasehold improvements and alterations, including without limitation, the furnishing and installation of air-conditioning units) and the installation of bathrooms in order to prepare the Substitution Space for its initial occupancy.

(a) From time-to-time, but not more than once a month, Tenant may give Landlord a Requisition for so much of the Work Cost as arose since the end of the period to which the most recent prior Requisition related, or, with respect to the first Requisition, for the initial Work Cost.

(b) If Tenant is not in material default under this Lease, within thirty (30) days after Landlord receives a Requisition, Landlord shall pay Tenant ninety percent (90%) of the Work Cost reflected in such Requisition and shall withhold the remaining ten percent (10%) of Work Cost (the “Retainage”); within thirty (30) days after Tenant furnishes Landlord with its final Requisition, which final Requisition shall reflect that all Tenant’s Initial Work has been completed and paid for in full by Tenant, Landlord shall pay Tenant all the Retainages.

(iv) The total payment to be made by Landlord shall not exceed the lesser of the total Work Cost or $400,000.00 (“Landlord’s Maximum Contribution”). The balance of the Work Cost shall be borne by Tenant.

(D) Tenant’s Final Plans shall comply with all rules and regulations and other requirements of any governmental authorities having or asserting jurisdiction over the demised premises or the building.

(E) Tenant may from time-to time prior to completion of Tenant’s Initial Work make such changes in the Tenant’s Initial Work as it deems appropriate, provided that with regard to any material changes (other than that required by governmental agencies) that would pursuant to Article 3 or 38 require Landlord’s consent, Landlord’s consent shall be obtained. Any such changes made prior to completion of Tenant’s Initial Work shall be considered part of Tenant’s Initial Work.

(F) Worker’s Compensation, public liability insurance, and property damage insurance, all in amounts and with companies and on forms reasonably satisfactory to Landlord, shall be provided and at all times maintained by Tenant’s contractors engaged in the performance of Tenant’s Initial Work and, before proceeding with the Tenant’s Initial Work, certificates of such insurance shall be furnished to Landlord.

With respect to each and every one of the insurance policies herein required to be procured by Tenant, on or before the commencement date and before any such insurance policies shall expire, Tenant shall deliver to the Landlord a duplicate original or certified copy of each such policy or a certificate of the insurer, certifying that such policy has been issued, providing the coverage required by this

In particular, if Tenant uses the demised premises for the preparation of food, Tenant shall reimburse Landlord or demand, for any part of the premium for insurance coverage required to be paid on account of such use of the demised premises.

(C) Landlord and Tenant hereby release and waive all rights of recovery against each other, their officers, directors, shareholders, partners, joint venture partners, employees and agents for any loss arising from any cause covered by any insurance required to be carried by each of them pursuant to this Article, or any other insurance actually carried by each of them even if the loss is due to the negligence of the other.

Each party shall cause its insurers to waive all rights of recovery by way of subrogation against the other in connection with any damage covered by any such policy.”

7. Upon Tenant’s written request, Landlord agrees to install a building standard skylight (“Skylight”) upon the Building’s roof in accordance with the provisions of this Article. Tenant expressly acknowledges that Tenant shall be responsible for fifty (50%) percent of any and all costs incurred by Landlord in connection with the Skylight (“Skylight Work”), including without limitation, the installation thereof, and such costs shall be paid upon demand therefor, provided that Landlord has delivered to Tenant evidence of such costs incurred and shall be deemed additional rent under the Lease. Landlord shall obtain two (2) bids from contractors for the performance of Skylight Work. Landlord’s solicitation of bids for the performance of Skylight Work, may include contractors designated by Tenant in writing, provided that such contractors are reasonably acceptable to Landlord for the performance of Skylight Work, and provided further, however, that Landlord’s previous experience with any such contractor may form a basis upon with Landlord may reasonably refuse to accept such contractor. Landlord shall forward to Tenant a copy of the accepted bid and within five (5) business days thereafter Tenant shall have the option to either (i) accept said bid in which event Tenant shall be responsible for the costs relative to the Skylight Work in accordance with the provisions of this Article; or (ii) reject such bid. If Tenant rejects the bid, Landlord will then submit to Tenant another bid for its consideration, provided however, that if Tenant rejects more than two (2) bids, Landlord shall have no further obligation to perform such Skylight Work. Supplementing the provisions of Article 4 of the Lease, Landlord shall be responsible for the repair of the Skylight, at Landlord’s, expense provided that any required repairs thereto are not occasioned by Tenant’s acts or omission. In addition, all repairs made by Landlord pursuant to this Article shall be conducted, to the extent practicable (but without the necessity of incurring overtime wages or other additional costs) in such manner so as to minimize interference with Tenant’s use of the demised premises.

8. Landlord represents that there is currently 150 amps 3 phase electric current available to service the Substitution Space. Anytime after the Substitution Space Commencement Date, Tenant may provide Landlord with a load letter, reasonably satisfactory to Landlord, evidencing Tenant’s need for additional electric power, up to a maximum of an additional 350 amps, with respect to the Substitution Space, and

5

Landlord shall make available such additional power to service the Substitution Space. Notwithstanding anything to the contrary contained herein, Landlord may, at its option, anytime during the term of the Lease, including without limitation the period of time immediately after which Tenant submits its load letter, have its electrical engineer survey Tenant’s electric current requirements and consumption thereof and issue a load letter as to the status of Tenant’s power requirement and consumption thereof. If said load letter states that (i) Tenant requirements and its then consumption level of electric current with respect to the Substitution Space, is less than the amount of amps then being distributed to Tenant, then in such event, Landlord may redistribute the balance of such power (i.e. the difference between Tenant’s then current consumption in amps and the amount of amps then being distributed to Tenant) and to other tenants in the Building or for Landlord’s Building systems; or (ii) is less than the amount of the amps reflected in Tenant’s load letter, then Landlord shall only be required to provide the additional amps as reflected in the load letter submitted by Landlord’s electrical engineer.

9. Promptly subsequent to the full execution of this Fourth Modification between parties hereto, Landlord agrees to provide Tenant with an ACP-5 certificate, or comparable certificate providing in effect that plans for alterations to be performed to the Substitution Space may be filed with the New York City Department of Buildings as a “no asbestos” project and that no action need be taken regarding asbestos with respect to the Substitution Space. In addition, Landlord will be responsible, at its sole cost and expense, to promptly encapsulate or remove any friable asbestos in the Substitution Space, provided however that any violations of laws relating to asbestos caused by Tenant’s construction shall be remedied by Tenant at its sole cost and expense.

10. In addition to the foregoing, the Landlord shall not be bound by any representations, understandings, promises or agreements not contained in the Lease or in this Fourth Modification, and this Fourth Modification shall not bind the Landlord and the Tenant until executed and delivered.

11. This Fourth Modification may not be changed, modified or canceled orally and shall be binding upon and inure to the benefit of the respective parties hereto, their successors, and except as otherwise provided in the Lease, their assigns. As modified and extended by the terms of this Fourth Modification, the Lease is hereby ratified and confirmed in all respects.

IN WITNESS WHEREOF, the parties hereto have executed this Fourth Modification as of the day and year first above written.

They shall incorporate all information which may be needed by Landlord to let the contracts for the performance of the work, and shall be fully dimensioned working drawings.
